⾼级英语答案(全)⾼级英语答案UNIT 1Part 1 Text-processingTeacher-aided WorkLead-inListen to the recorder and take notes. Then fill in each gap in the following passage with ONE word according to what you have heard. Finish your work within 10 minutes.Tape script:E. B. White was born in 1899 in Mount Vernon, New York. He served in the army before going to Cornell University. There he wrote for the college newspaper, the Cornell Daily Sun. After he graduated, he worked as a reporter for the Seattle Times in 1922 and 1923. As he put it, he found that he was ill-suited for daily journalism, and his city editor had already reached the same conclusion, so they came to an amicable parting of the ways.In 1927 he became a writer for The New Yorker magazine, where he became well k nown. He wrote columns for Harper’s magazine from 1938 to 1943, which resulted in an anthology entitled One Man’s Meat and published in 1942.White’s career had already brought him much fame, but he was about totry something new. His nieces and nephews always asked him to tell them stories, so he began writing his own tales to read to them. In 1945 he started publishing these stories as books. All three, Stuart Little (1945), Charlotte’s Web (1952) and The Trumpet of the Swan (1970), are now considered cla ssics of children’s literature.His best essays appear in three collections: One Man’s Meat (1944), The Second Tree from the Corner (1954) and The Points of My Compass (1962).In 1959, White edited and updated The Elements of Style. This handbook of gramm atical and stylistic dos and don’ts for writers of American English had been written and published in 1918 by William Strunk Jr., one of White’s professors at Cornell. White’s rework of the book was extremely well received. The volume is a standard tool for students and writers, and remains required reading in many composition classes.In 1977 he was awarded a Pulitzer Prize for his lifetime’s work.White died on October 1, 1985 at his farm home in North Brooklin, Maine, after a long fight with Alzheimer's Disease. He was cremated, and his ashes were buried beside his wife at the Brooklin Cemetery.A leading essayist and literary stylist of his time, White is known for his crisp, graceful, relaxed style. To him, “style not only reveals the man, it reveals hi s identity, as surely as would his fingerprints.” (The Elements of Style) The subtlety, the sentiment, the facility and sensitivity withwords—all mark him out from his fellow essayists.“Once More to the Lake”, selected from E. B. White’s One Man’s Meat, is the story of a man returning to his younger days by revisiting a lake from his childhood. Throughout the trip he hovered between being an older man and a younger boy and felt that “the years were a mirage and there had been no years.” But throughout the story, there are small hints that are just enough not to let him fall completely into his dream and to remind him that man is mortal after all.Passage for gap-filling:E. B. White, an American writer, was born in 1899. After his graduation from Cornell University in 1822, he reported for a newspaper. In 1927 he became a writer for The New Yorker magazine. He wrote 1) columns for Harper’s magazine from 1938 to 1943. In 1945 he started publishing 2) tales he had written for his nieces and nephews in book form. White wrote a large number of 3) essays, and the best of them were published in three collections. In 1959, he edited and updated The Elements of Style, a handbook by one of his professors at Cornell. In 1977 he was awarded a Pulitzer Prize for his lif etime’s work, and he died in 1985.“Once More to the Lake”, selected from his One Man’s Meat, is the story of a man returning to his younger days by coming back to a lake he had visited when a boy. Throughout the trip he felt that he had a 4) double identi ty and that “there had beenno years.” But throughout the story,there are just enough hints to remind him that time passes and man must 5) die after all.In-depth Comprehension1. Questions1) Para 1: What happened to the author’s father when he was in a canoe? Was it good or bad? How do you know?His father’s canoe overturned and he fell into the lake with all his clothes on. That was something bad, for it is mentioned together with another bad thing—getting ringworm, and is excluded from what made the visit a success.2) Para 1: What does “a saltwater man” mean? Since when has the author become a saltwater man? Give your reasons.“Saltwater” here refers to seawater, which is salty. “A saltwater man” doesn’t mean a man who drinks saltwater, but one who bathes in the sea, because the intention in going to the seaside was to vacation there. (Attention: One should be careful about the actual relation between a noun as modifier and the noun modified) Most probably, the author has gone to the seaside for vacation instead of the lake in Maine since he got married and had a family of his own.3) Para 2: What does the author mean by saying his son “had never had any freshwater up his nose” and “had seen lily pads only from trainwindows?”He means that the boy had always gone with him to the seaside for his holidays and never bathed in a freshwater lake where you often find lily pads, that is, water lily with its large, floating leaves. He had only seen them from train windows. The author here states the result (freshwater up his nose) rather than the cause (swimming in freshwater), which is a case of metonymy.4) Para 2: How could the tarred road, which had no life, have “found out” the lake? What is the author’s real meaning? Was it good or bad in the author’s o pinion? What is your reason for this conclusion?The lifeless tarred road is here personified (compared to a human being) by the use of the verb “found out”. The author’s real meaning is that the tarred road must have extended to the lake. He views it as a bad thing, because he mentions it together with “other ways it (the lake) would be desolated.”5) Para 2: How can a person’s mind move in grooves, which are physical? How would the author have said it in plain words?A groove is a long narrow hollow path or track in a surface, esp. to guide the movement of something. Here a person’s mind is compared to something that moves in grooves. In plain words, the author would have said “Once you recall the past.”6) Para 2: What does “clear” in “extend clear to” me an? How would theauthor have probably described the partitions if he had used an affirmative sentence? What is the author’s intention in describing the partitions?Here “clear” means “all the way”. Using an affirmative sentence, the author would probably have said “The partitions in the camp were thin and there were blanks between their tops and the top of the rooms.” He describes the partitions to imply that they were not soundproof and that that was the reason for his soft actions.7) Para 2: Is it possible that there is a cathedral on the shores of the lake? If not, what does “cathedral” really refer to? And why does the author call it a cathedral?A cathedral is a big church that serves as the official seat of a bishop, which is usually located in a fairly large town or city. So it is impossible that there is a real cathedral by the lake. The author here is comparing the lake, which is holy to him, to a cathedral.8) Para 3: What is the author’s intention in saying “you would live at the shore and eat yo ur meals at the farmhouse?”He says this to imply that the farmhouses were very near to the shore of the lake, which in turn supports the idea that the lake had never been what you would call a wild lake.9) Para 5: What is a mirage? What does the author m ean by “the years were a mirage and there had been no years?”A mirage is an optical effect sometimes seen at sea or in a desert caused by bending or reflection of light by a layer of heated air (海市蜃楼). Here it refers to something unreal, illusory. The author means that the years that had passed appeared to be unreal because nothing of consequence had really changed.10) Para 5: Does a rowboat really have a chin? What does “chucking the rowboat under the chin” mean?Both the rowboat and the lake are personified by the use of the words “chuck” and “chin”. “Chuck”, here meaning “stroke gently with the hand”, refers actually to “beat very lightly”, and “chin” here refers to that part of the bow (the front part) which protrudes over the water.11) Para 5: Which does “catch” in “the dried blood from yesterday’s catch” refer to, an action or things? What is your reason?“Catch” here does not mean the action of catching, but what is caught, referring specifically to fish that had been caught, because “yesterday’s catch” could shed blood.12) Para 5: Was it really the author’s hands that held his son’s rod, his eyes that were watching? If not, what does he mean?“It was my hands that held his rod, my eyes watching” simply repeats what is meant by “I began to sustain the illusion that he was I” in Paragraph 4.13) Para 6: Which is usually bigger and stronger, a bass or a mackerel?Give your reasons.A bass is usually bigger and stronger than a mackerel, because the angler usually has to use a landing net when pulling in a bass, while he does not have to do so when landing a mackerel.14) Para 6: Can a lake move to another place? If not, why does the author say “the lake was exactly where we had left it?”Here “the lake” refers to the level of the body of water. If the level rises, it will cover a wider area, and will seem to have moved.15) Para 6: What does “attendance” mean? How is the attendance doubled?“Attendance” usually means the number of people present on a particular occasion, but here refers to the number of minnows swimming in the water. The attendance was doubled by their shadows.16) Para 6: What does “cultist” mean? Whom does “this cultist” refer to in this context?“Cultist” means “a follower of a particular custom”, here referring to the person always washing himself with a cake of soap.2. Multiple-choice Questions1) The author would like it better _______A________.A. if the lake were completely wildB. if there were more farmhouses near the lakeC. if the lake were more easily accessible by carD. if they could eat right in their campExplanation:The phrase “wish for the placidity of a lake in the woods” and the sentence “I was sure the tarred road would have found it out and I wondered in what other ways it would be desolated” show that the author likes a wild lake which is not spoilt by human activity.2) The arrival of the author and his family at the lake is described in Paragraph _______C_______.A. 2B. 3C. 4D. 5Explanation:Paragraph 4 begins with “I was right about the tar: it led to within half a mile of the shore” and that indicates that the a uthor is beginning to describe what he actually saw of the lake area on this trip, while the previous paragraphs only tell about hisrecollections and guesses.3) What is common to Paragraphs 4, 5, and 6 is _______D_______.A. that they are about the same lengthB. that they are of the same degree of difficultyC. that they tell about the experiences of the same peopleD. that they describe the illusion of the exact repetition of the same scenesExplanation:“It was going to be pretty much the same as it had been before” in Para4, “everything was as it always had been” in Para 5, “there had been no years” in Para 6 and the frequent repetitions of the word “same” in these paragraphs show that the answer is D.4) Which of the following is false? _______A_______A. Paragraph 3 describes the lake as the author sees it when he visits it this time.B. Paragraph 4 tells about the resemblance of the father and son of the present to those of the past.C. Paragraph 5 focuses on the sameness of the scenes of fishing at different times.D. Paragraph 6 emphasizes the unchangeableness of the lake.Explanation:“That’s what our family did” and “there were places in it which, to a child at least, seemed infinitely remote and primeval” hint that the author is describing his impressions of the lake when he came as a child with his father, not as a father on this trip.5) From this excerpt we can see that the author ________B________.A. is a conservativeB. is a nostalgic nature-loverC. is a muddle-headed person who cannot tell the present from the past.D. lives a double life.Explanation:The author loves the wild lake, and hates it’s being spoilt by human activity. He indulges in recollections of the past and often feels as if there had been no years. So we say that he is a nostalgic nature-lover.Extension from the Text1. SpeakingBased on clues in the text alone, say something about the author (his nationality, the approximate date of his birth, his age when he wrote this essay, his family, etc.) and give reasons for what you say.The author was American because when he was still a boy his family often visited a lake in Maine, which is a state of the US. In the year 1904, he was still a teenager, so he was probably born around 1890. When he wrote this essay he had a son about the same age as he had been when he went with his father to the lake, so he was now about forty. Most probably, he had a family of three, because he had only one son and must have hada wife though he never mentions her.2. ClozeUp to the farmhouse to dinner through the teeming, dusty field, the road under our sneakers was only a two-track road. The middle track was missing, the 1) one with the marks of the hooves and the splotches of dried, flaky manure. There had always been 2) three tracks to choose from in choosing which track to walk in; now the 3) choice was narroweddown to two. For a moment I 4) missed terribly the middle alternative. But the way led past the tennis 5) court, and something about the way it lay there in the sun reassured me; the tape had loosened along the backline, the alleys were green with plantains and other 6) weeds, and the net (installed in June and removed in September) sagged in the dry noon, and the whole place steamed with midday 7) heat and hunger and emptiness. There was a choice of pie for dessert, and one was blueberry and one was apple, and the 8) waitresses were the same country girls, there having been no 9) passage of time, only the illusion of it as in a dropped curtain—the waitresses were still fifteen; their hair had been washed, that was the only 10) difference—they had been to the movies and seen the pretty girls with the clean hair.Explanations:1) “The . . .” is in apposition to “the middle track” and refers to it. “One” is used to avoid the repetition of “track”.2) “A two-track road” and “the middle track was missing” tell us that there had been three tracks before.3) “Three tracks to choose from” and “. . . was narrowed down to two” show that the blank must refer to “the number of things to choose from”, which is the meaning of “choice”.4) As the middle track was missing, the relation between the author and the track can only be mental, and the word “terribly”shows that it isemotional—regretting the absence of something one loved. So “missed” is the right word.5) “The way led past . . .” and “it lay there” indicate that “the tennis . . .” refers to a location related to the game of tennis, so it must be the tennis “court”. This is further proved by the description of the “tape”, “alleys” and “net”.6) “Plantain” is a weed, “other . . .” must be “other weeds”.7) “June”, “September”, “noon”, “steamed” and “midday” all connote high temperature. In “steamed with . . . “, the blank states the reason for “steaming”, which can only be “heat”.8) The subject of “. . . were the same country girls” must refer to females. These females must be related to the supply of such foods as blueberry pie and apple pie. So they were either cooks or waitresses. But “the whole place” was not the author’s home,so the females were not cooks, but waitresses, who are further described later in the passage.9) In “no . . . of time”, the blank must refer to a phenomenon with “time”, which is either “passage” (a noun derived from the verb “pass”) or “stopping”, or “waste” or “saving”. “No passage of time” is reasonable because “the waitresses were the same country girls.”10) The waitresses were the same as those of the past in age—still fifteen. But they had washed their hair because they had been to the movies and seen the pretty girls with the clean hair, whereas the waitresses of the pasthad had no chance of seeing movies, which did not appear until 1911. So the clean hair was a “difference.”3. TranslatingTranslate the underlined part of the following passage into Chinese. Summertime, oh summertime, pattern of life indelible, the fade-proof lake, the woods unshatterable, the pasture with the sweet fern and the juniper forever and ever, summer without end; this was the background, and the life along the shore was the design, the cottagers with their innocent and tranquil design, their tiny docks with the flagpole and the American flag floating against the white clouds in the blue sky, the little paths over the roots of the trees leading from camp to camp and the paths leading back to the outhouses and the can of lime for sprinkling, and at the souvenir counters at the store the miniature birch-bark canoes and the post cards that showed things looking a little better than they looked. This was the American family at play, escaping the city heat, wondering whether the newcomers in the camp at the head of the cove were “common” or “nice,” wondering whether it was true that the people who drove up for Sunday dinner at the farmhouse were turned away because there wasn’t enough chicken.……这⼀切是底⾊,湖四周的⽣活是这底⾊上的图案。

Earlier this month, workers gathered buds from tall, old trees on the grounds of George Washington’s home, Mount Vernon. It is in the state of Virginia, near Washington, D-C. The experts hope to produce genetic copies, or clones, of the trees and plant them on the property.Tree experts David Milarch (MILL-ark) and his son, Jared, are leading the efforts. They gained experience in cloning old trees through the Champion Tree Project. They started the project to produce genetic copies of the largest trees in the United States. Over the next ten years, the project plans to provide Mount Vernon with one-thousand trees for planting in nearby wooded areas.During the past century, Mount Vernon has lost more than seventy trees that were planted when George Washington was alive.As a special project, David and Jared Milarch offered to make clones of the thirteen oldest trees at Mount Vernon. They are huge, beautiful trees. George Washington supervised the planting of these trees more than two-hundred years ago.The Milarch family plans to grow fifty copies of each tree in tree nurseries in Alabama and Oregon. They will return the trees to be planted at Mount Vernon in two years. Some copies of the trees will be sent to the Arnold Arboretum at Harvard University in Cambridge, Massachusetts for safe keeping.Grafting is the name of the process used to clone trees. It has been done for thousands of years. A method called the T-bud technique often is used to copy trees.Workers begin by cutting the bark, or covering, on the side of a young tree. The cut is made in the shape of a cross, or the letter T. Next, the workers find a bud, or small growth, on the tree to be copied. A small piece of wood under the bud is carefully removed from the tree. The bud is then put into the hole on the other tree. The bud is tightly tied in place and begins to grow.Mount Vernon officials say George Washington was interested in his tree collection. The officials add that he was a strong environmentalist. They say the old trees are important because they existed when America’s first president was alive.This VOA Special English Science Report was written by George Grow..» » Publishers: Please contact us if you would like to use our scriptsE-mail: special@ Web: /specialFax: 202-619-2543VOA Special English Washington, D.C. 20237 USA.。

The Dual Axis Motor Drive is essential for users wanting electronic RA tracking capabilities on their Meade LX70 and those interested in beginning astro-photography. In addition, the Dual Axis Motor Drive gives elec-tronic control of both axes enabling fi ne slow motion slewing control to the user through a keypad. For both the novice user and budding astro-photographer, use of the optional Meade #670010 Polar scope is recommended.Before beginning the below installation procedure it’s recommended to remove the optical tube and counterweight from the mount. When completed, reinstall the optical tube and counterweight, then perform a polar alignment on the night sky as described in your mount’s user manual.Tools Needed:• Phillips screw driver • 4 mm hex wrench • 2 mm hex wrench • 5 mm hex wrench Installing the RA motor drive1. Remove both front and rear latitude adjustment knobs on the LX70 mount so the mount head can pivot its full range of motion. See Figure2.2. Remove the RA motor cover by removing the small Philips screw located on the bottom side of the cover. Set the motorcover and Philips screw aside. See Figure 3.3. Using your hand or slow motion control cable, rotate theRA worm shaft until the fl at portion at the shaft end faces in the direction of the front north tripod leg. See Figure 4.4. Attach the brass spur gear assembly onto the shaft on the left side of the mount and secure with the 2mm hexwrench. The setscrew must be tightened against the fl atsurface on the shaft end. See Figure 4.5. Pivot the mount head downward until it stops. This will be at a latitude scale reading near 25°.6. Using the 4mm hex key and 35mm long screw, insert the long screw into the mount as shown in Fig 6. Use the hexkey to hold the screw in place.7. Place the RA motor assembly onto the mounting plate lo-cated on the front of the mount. The mounting plate should be positioned so the brass gears align and mesh well with each other. See Figure 7 & 8. 8. Using the 4mm hex key and 35mm long screw, securethe RA motor in place. See Figure 6 & 7.9. Pivot the mount head upward until it stops. This will be at a latitude scale reading near 60°.Figure 6Figure 4Figure 5Figure 7Figure 1Batterybox DEC Motor Assembly RA Motor Assembly 35mm longscrew Hand Controller RA & DEC Spur Gears 2mm wrench 5mm wrench 4mm wrenchScrewdriver15mm longscrewFigure 2RemoveRemove Figure 3Remove screw, then motor coverInstall spur gearonto shaft Use 2mm wrenchto tightenInstall 35mm screw into mountInstall RA MotorAssembly10. If desired, remove the black plastic oval on the RA motor cover side and slide the RA motor cover back onto the mount. Secure in place with the Philips screw.11. The RA slow motion control cable and latitude adjustment knobs that came with the mount can now be secured as described in the LX70 instructional manual. See Figure 9.Installing the DEC motor drive1. Using your hand or slow motion control cable, rotate the DEC worm shaft until the fl at portion at the shaft end faces outward. See Figure 10.2. Attach the brass spur gear onto the longer DEC worm shaft and secure with the 2mm hex wrench. The setscrew must be tightened against the fl at surface on the shaft end. See Figure 10.3. Place the Dec motor assembly against its mounting plate and insert the 15mm long hex screw on the top side hole lightly securing the motor assembly in place using the 5mm hex wrench. See Figure 11. Adjust the motor assembly until the two brass gears are aligned before fi rmly tightening the screw. See Figure 8 & 12.4. The DEC slow motion control cable that came with the mount can now be secured as described in the LX70 instruc-tional manual. See Figure 13.Connecting the hand controller1. Locate the hand controller and note the two cables at the bottom. Connect the cable labeled DEC to the connector at-tached to the DEC motor assembly. See Figure 14.2. Connect the cable labeled RA to the RA motor assembly by inserting the cable thru the hole on the bottom side of the RA motor cover. See Figure 15.3. Next connect the cable attached to the battery holder to the hand box port labeled 6V DC Power. See Figure ing the motor drive & hand controller (Reference Figure 16)The Meade LX70 Dual Axis Motor drive requires 4 “D” size batteries. Begin by installing the batteries into the battery box and note the correct polarity markings shown in the battery holder. If not already connected, connect the battery box to the hand controller port labeled 6V DC Power. See Figure 16.Figur e 8Figure 9Figure 10Figure 11Figure 13Ensure proper gear meshInstall RA Slow Motion Control CableInstall spur gear onto shaftInsert 15mm screwInstall DEC Slow Motion Control CableFigure 15Connect RA Hand Controller CableFigure 14Connect DEC Hand Controller CableTo turn on the motor drive, users in the northern hemisphere should slide the on/off switch to “N”. Users in the southern hemisphere should slide the on/off switch to “S”. When the drive is powered, a green LED will illuminate on the hand con-troller and the RA motor will begin to turn slowly.NOTE: The DEC motor will not move until commanded by the hand controller.When the battery power gets low, the LED will begin to fl ash indicating they should be replaced. A set of new alkaline bat-teries should last several nights of observing under normal conditions.T o use the motor drive to its fullest potential a proper polar alignment on the night sky is needed. Follow the instructions in your LX70 mount manual to perform this alignment. If using the optional Meade #670010 polar scope, follow the included instructions. Once the telescope is accurately polar aligned, the dual axis motor drive can be used to track night sky ob-jects at the sidereal rate.With the motor drive installed, each axis can be engaged/disengaged from the motors by locking/unlocking the friction clutch. T urn the clutch knob clockwise to engage the motor drive and allow the hand controller to control each axis. See Figure 18.NOTE: When the motor drive clutch is engaged, the slow motion control cables cannot be used.T urn the clutch knob counter-clockwise to disengage the motor drive system and allow the slow motion control knobs to move the axis. When use of the slow motion control cable is complete, re-engage the drive clutch by turning the clutch knob clockwise.T o move the mount using the hand controller, lock both mount RA and Dec locks and motor drive clutch knobs for each axis. See Figure 18 & 19. Then select the desired motor speed on the hand controller using the switch labeled 2X-4X-8X at the top of the hand controller. See Figure 16. Press and hold the direction button desired. When the motor is being driven, a red LED will illuminate on the hand controller.Note the following motor speeds:• 2X sidereal speed will drive the mount at 1/2° per minute.• 4X sidereal speed will drive the mount at 1° per minute.• 8X sidereal speed will drive the mount at 2° per minute.Locate night sky objects by moving the mount as described in the LX70 instructional manual.

Designing and Manufacturing an Appropriate Technology Shredder in a Developing CountryJeffrey P. WeissAn Engineering Project submitted to the faculty of the School of Engineering in partial fulfillment of the requirements of the Masters of Manufacturing Systems Engineering degreeUniversity of St. ThomasSt. Paul, MinnesotaDecember 2005AbstractThe focus of this project was to redesign a simple manual shredding machine used to shred breadfruit for the Republic of Haiti. A breadfruit shredder previously designed by a student senior design team was used as the basis for this project. The objective was to apply manufacturing principles, such as Design for Manufacturing and Assembly (DFMA), to simplify and reduce the cost of this machine so that it would be more accessible to poor farmers in Haiti. Each part of the shredder was examined using the DFMA methodology to determine if it could be eliminated or redesigned to simplify it while still making a quality product that met the performance criteria. The limitations of manufacturing a product in a developing country were also taken into consideration and played a key role in the outcome of the design. The result was a design that had a reduced number of parts, was more robust, easier to clean, simpler to build in a developing country, used materials that were more commonly available, and cost less to make.Revised Tommy Breadfruit ShredderAcknowledgementsI would like to acknowledge and send my sincerest thanks to my Project Committee of Dr. Camille George, Dr. Fred Zimmerman, and Mr. John Walker. They contributed numerous ideas during both the project phase and during the writing process. This resulted in a much better product that will hopefully improve the lives of people around the world. Dr. George also spent a great deal of time correcting and critiquing the writing of someone who was unaccustomed to writing in the academic thesis style.Many other people also lent a voice to the project during the research and design review phases. This would include Karl Mueller, Bruce Humphrey, Hank Garwick, Dave Elton, John Schevenius, Gary Olmstead, Fred Hegele, Pat O'Malley, Troy Pontgras, Yvonne Ng, and Clay Solberg. These people took the time to help and offered ideas that had previously been missed, resulting in a better product.I would also like to acknowledge the contribution of Dr. Mike Hennessey at the University of St. Thomas and the work of five of his undergraduate students. Justin Jackelen, Michael Boston, Angela Wachira, Keli Lais, and Matt Ellision took on the task of turning the revised breadfruit shredder drawings into computer animated Solidworks models. This contributed greatly to the visual understanding of the project and presentation. They also provided the fabrication prints that accompany this paper.Table of ContentsChapter I: Introduction (1)The Haitian Situation (2)Breadfruit (3)The Tommy Shredder (5)The Beneficiaries (5)Project Motivation (6)Chapter II: Research and Prior Work (7)UST Senior Design Team Work (7)Literature Search (9)Compatible Technology, International (11)Institutional Libraries (15)Research and International Organizations (15)Expert Inquires (17)Chapter III: Project Proposal (18)Project Objectives (18)Alternative Methods (20)Project Constraints (21)Project Budget (23)Financial Justification (23)Chapter IV: Findings and Results (24)Redesign Process (25)Design for Manufacture and Assembly Process (25)Alternative Designs (29)Design Reviews (30)Design Modifications (33)Fabrication Lessons (38)Design Variations (40)Shredder Blade Project (41)Testing the Redesigned Shredder (45)Redesign Results (47)Schedule (50)Final Budget (51)Chapter V: Discussion and Ramifications (52)Project Dissemination (52)Implementing the Shredder in Developing Countries (53)Project Obstacles (54)Bibliography: (57)Appendices (60)Appendix 1: Revisions 1 and 2 (60)Appendix 2: Revisions 3 and 4 (61)Appendix 3: Revisions 5 and 6 (62)Appendix 4: Revision 7 and 8 (63)Appendix 5: Breadfruit Shredder Exploded Layout (64)Appendix 6: Bill of Materials – Breadfruit Shredder (65)Appendix 7: Frame Plate Fabrication (67)Appendix 8: Drive Shaft Fabrication (69)Appendix 9: Feeder Tube Fabrication (70)Appendix 10: Blade Mount Fabrication (71)Appendix 11: Shredder Press Weight Fabrication (73)Appendix 12: Shredder Assembly Instructions (74)Appendix 13: Original Project Schedule (77)Appendix 14: Revised Project Schedule (78)Appendix 15: Preliminary Sketch by John Walker (79)Appendix 16: Contributions by Karl Mueller (80)Appendix 17: Drawing #001 – Frame Plate (82)Appendix 18: Drawing #002 – Drive Shaft (83)Appendix 19: Drawing #003 – Feeder Tube (84)Appendix 20: Drawing #004 – Drive Shaft Bearing (85)Appendix 21: Drawing #005 – Handle (86)Appendix 22: Drawing #006 – Blade Mount (87)Appendix 23: Drawing #007 – Center Divider (88)Appendix 24: Drawing #008 – Center Divider Spacer Tube (89)Appendix 25: Drawing #009 – Shredder Press Weight (90)Table of FiguresFigure 1: Map of the Republic of Haiti (CIA Fact Book, 2005) (3)Figure 2: Fruit of the Breadfruit Tree () (4)Figure 3: Senior Design Team Shredder (8)Figure 4: Garwick/Elton Breadfruit Shredder (13)Figure 5: Garwick/Elton Bicycle Drive Mechanism (14)Figure 6: Original Tommy Shredder Exploded View (28)Figure 7: Handle/Drive Shaft Changes (34)Figure 8: Drive Shaft Bearing Changes (35)Figure 9: Frame Plate Changes (35)Figure 10: Center Divider Changes (36)Figure 11: Blade Mount Changes (37)Figure 12: Combined Feeder Tube Hoop and Spacer (38)Figure 13: Alignment of Bushing Supports (39)Figure 14: Wooden Bushing Variation (41)Figure 15: Shredder Blade Profile Die, Profile Punch, and Hole Template (43)Figure 16: Fabricated Blade (45)Figure 17: The Revised Tommy Shredder (48)Table of TablesTable 1: Haiti Facts (CIA Fact Book, 2005) (2)Table 2: Proposed Budget (23)Table 3: Shredder Punch Hole Test (44)Table 4: Final Budget (52)Chapter I: IntroductionThis project will focus on redesigning for manufacture a simple breadfruit shredder for the Republic of Haiti. As one of the poorest nations in the Western hemisphere, Haiti is a country that lacks a stable government, education system, manufacturing base, or infrastructure. Malnutrition is a problem to the extent that the United States Department of State estimated that the child malnutrition rate was 22 percent in 2000(). Breadfruit is a natural food resource that is underutilized because it rots quickly and is difficult to store using traditional methods. Drying breadfruit can extend its shelf life and this process is best done when the shreds are even and consistent.A simple manual shredder was developed to produce consistent shreds for the inhabitants of Haiti by a group of senior engineering students at the University of Saint Thomas (UST) in conjunction with Compatible Technology International (CTI), an international non-profit organization. The student version of the shredder was designed and tested and found to meet all of the criteria that they had established. Despite meeting the requirements, the machine had the potential to be optimized to better reflect the manufacturing capabilities available in a developing country. This paper will document the redesign process and look at the manufacturing principles that drove this process. The end result was a machine that was simpler to build with the basic machine tools that would normally be found in a developing country such as Haiti, used materials that were more commonly available, had a reduced number of parts, was more robust, was easier to clean, and had a reduced cost.The Haitian SituationHaiti is considered to be the poorest and most destitute country in the Western hemisphere (CIA Fact Book, 2005). A majority of its population lives in poverty and relies on subsistence farming for survival. It has a long history of political upheaval and unrest since it gained its independence from France in 1804. The rotation of various governments and civil wars has hindered investment in the country and led to high unemployment and dismal living conditions for its inhabitants. The education system is broken or non-existent and there has been an exodus of knowledge from the island as people flee the dire conditions and turmoil.Table 1: Haiti Facts (CIA Fact Book, 2005)Population (Estimate, 2004): 8,121,622Land Area: 27,750 sq kmAverage Life Expectancy: 53 yearsPopulation Below Poverty Line: 80%Percentage of Population in Agriculture: 66%Unemployment Rate (no formal job): 66%Average Literacy Rate: 52%Figure 1: Map of the Republic of Haiti (CIA Fact Book, 2005)Most of the original Haitian forests have been cut down for fuel and the desire to cultivate more land. The weak governments have been unable or unwilling to confront this problem and it has continued unchecked. This deforestation has resulted in massive land erosion in the mountainous country and a net loss of arable land (CIA Fact Book, 2005). Breadfruit trees are abundant throughout the island and are one of the few trees that have survived the deforestation process.BreadfruitBreadfruit is an important food source and has become a staple for the inhabitants of warmer islands in the Caribbean Sea and Pacific Ocean. It has some nutritional value anda high starch content (Adebowale, 2005). Typical ways of preparing breadfruit are grilling, roasting, adding it to soups, and mashing.Figure 2: Fruit of the Breadfruit Tree ()One of the unique properties of breadfruit is its limited shelf life. Once it ripens and comes off of the tree, it will last between one and three days ( ). The breadfruit trees of Haiti produce fruit twice a year for a three week period (six weeks per year). Much of the fruit rots on the ground because of the inability to consume it all for the short time that it is in season (Capecchi, 2005). Typical preservation methods for fruit, such as canning, can be done but these value-adding processes are not common in Haiti and will increase the price of the food. A more economical way of preserving the breadfruit needed to be developed to utilize its potential to alleviate long-term hunger on the island.The Tommy ShredderThe development of a breadfruit harvesting process was taken on by two groups of senior mechanical engineering students as their Senior Design Projects in the 2003-2004 academic year. The first team attempted to devise a solar drier to quickly dehydrate the shredded breadfruit. The drying project showed that the shredded fruit could be successfully air-dried with an optimal shred size of ½” wide (Emiliusen, Mauritzen, McGruder, and Torgerson, 2004). The dried product can be stored for up to a year.The second team worked on developing a small, economical shredder that could efficiently and quickly process the breadfruit down into shreds so that it could be dried (Anderson, Fox, Rick, and Spah, 2004). The concept and methodology for the basic shredder design was done by the senior design team as was the testing to prove out the final design and will not be repeated in this paper. The purpose of this project was to examine and simplify the design, focusing primarily on its manufacturability.The BeneficiariesThe target beneficiaries of this shredder will be women’s cooperative groups based in Haiti. CTI, whose mission is to bring appropriate technologies to help increase food supplies and storage capacities in the developing world, has been working with the Methodist Church missions in Haiti on preserving breadfruit. Dried breadfruit can be ground into flour and local CTI volunteers have created several recipes using this breadfruit flour as the bulk material. UST teamed up with CTI to develop a simple shredder that could be used to shred the breadfruit. The goal of this joint project was tocreate a shredder that was simple to use and economical to manufacture so that local versions could be bought with micro-loans managed by the Methodist Church of Haiti. CTI also planned on helping set up a program to buy the shredded/ground breadfruit and process it into a cereal for Haitian school children (Capecchi, 2004). The plan was to take a resource, preserve it and add value, and then process it to create a commercial good. The objective of this undertaking is to give the women’s co-ops a starter model shredder that would allow them to generate some income from a readily available raw material.This shredder is also capable of processing a variety of different produce. There have been inquiries into its ability to shred cassava, sweet potatoes, and red peppers. The alternative uses of the shredder will not be explored here but the final design for this project will be made readily available and has potential uses worldwide. It will also be submitted to appropriate technology journals to broaden its dissemination.Project MotivationThe author of this master’s engineering project has spent time in developing countries and realized that there are often raw materials that are not fully utilized and exploited. The people generally lack the knowledge to manufacture items in large volumes and have limited manufacturing equipment, start-up money, a reliable source of power, or an infrastructure to transport the goods (Obi, 1999). However, these people are extremely creative and will adapt what they have on hand to work in almost any situation (Humphrey, 2005). The motivation for this project was to help the people develop theirown economy and hopefully raise their standard of living. This project will not only benefit the women of Haiti, it will help the local machine shops, provide work at the processing plant, and give the children of Haiti a stable, year around diet.Chapter II: Research and Prior WorkThe research for this project consisted of searching major journals, books on manufacturing in developing countries, contacting major research libraries, and personal contacts with experts in various fields. Many avenues for help were explored to gather information to improve the final design. The research phase of this project found that the work done by the UST senior design team was one of the few to address the issue of constructing a simple shredder for manufacture and use in a developing country.UST Senior Design Team WorkThis project is based on the work previously done by a University of Saint Thomas (UST) senior engineering design team whose goal was to develop the original breadfruit shredder based on the needs of the country of Haiti and the criteria established by Compatible Technology, International (CTI). The purpose of the original project was to “find the most efficient means of mechanically shredding breadfruit to best prepare the fruit for the drying process” (Anderson et al, 2004). The team developed concepts and tested many different methods of shredding the breadfruit and the mechanical actuators that would be needed for each prototype. The concepts were evaluated and ranked and the team chose the method best suited for their needs. The ‘Tommy Shredder’ developedby the student senior design team is shown in Figure 3 and their paper can be found on the UST website at /cmgeorge/breadfruit_shredder/.Figure 3: Senior Design Team ShredderThe senior design team had originally planned on testing the shredder in its target environment of Haiti but that country was not accessible at the time due to political unrest. A prototype shredder was built and brought to the Caribbean island of St. Vincent where there was an ample supply of breadfruit and established contacts. On the island of St. Vincent, the design was field-tested using breadfruit and the results recorded. The shredder met all of the target criteria established by CTI and the design team. It produced an average shred rate of 200 pounds/hour and cost less than $100 dollars U.S. to build (Anderson et al, 2004). This shredder became the baseline for the current project.Literature SearchA literature search done using the Compendex database at the University of Minnesota found several articles that were possibly related or relevant to the design of the breadfruit shredder. These articles were retrieved and analyzed with the result being that a majority were not related or did not contain information relevant to the design of an appropriate technology machine. Many of the applicable articles are referenced throughout this paper while those with less relevance to the project are cited in this section.In ‘Functional Properties of Native, Physically and Chemically Modified Breadfruit (Artocarpus Artilis) Starch’, Adebowale, Olu-Owolabi, Olawumi, and Lawal (2005) dealt with extracting starch from breadfruit. In the ‘Rediscovery of Local Raw Materials: New Opportunities for Developing Countries’, El-Mously (1997) discussed ways that developing countries could use local, undervalued resources to reduce their dependence on foreign imports. Breadfruit would be an undervalued resource on most Caribbean islands but the article did not provide information that would be relevant to the design of a shredder or this project. In the ‘Framework for Selecting and Introducing Appropriate Production Technology in Developing Countries’, Bruun and Mefford (1996) looked at working with the culture and education of developing countries when setting up a production facility. These are issues that will not be dealt with in this paper. In the ‘Role of Materials in Developing Countries’, Villas-Boas (1990) discussed the lack of use of new, high-tech materials in developing countries due to their cost and availability. Every effort was made to design the shredder using only common materials that would typicallybe available in a poor, developing country. In the ‘Supplier Selection in Developing Countries: a Model Development’, Motwani, Youssef, Kathawala, and Futch (1999) discussed issues involving selecting or qualifying vendors to produce a product. This will be the responsibility of the organization having the shredder built, and is beyond the scope of this project.A search of the Internet using the Google – Advanced Scholar provided more papers that had some relevance. Thakur, Varma, and Goldey (2001) in the ‘Perceptions of Drudgery in Agriculture and Animal Husbandry Operations: A Gender Analysis From Haryana State, India’ discusses the fact that women in developing countries spend much more time working in agriculture than men and the tasks given to them are more monotonous and tedious. The article supports the need for a device like the breadfruit shredder that has the potential to lift them out of that situation. In ‘A Framework for Implementing Appropriate Manufacturing Systems in Developing Economies’, Obi (1999) looked for explanations on why the Industrial Revolution passed by most developing countries and explored ways that these countries can start utilizing their vast manpower resources. He discusses the need to change workers attitudes. Finally, in ‘Meeting a Pressing Need’, Hynd and Smith (2004) discuss a simple oilseed ram press as an appropriate technology device for small scale extracting of oil from seeds and nuts. They examine some of the cultural issues that were associated with implementing the oilseed ram. The insights of this article could be used as a guide for undertaking the next phase of the shredder project; implementation into the Haitian culture. They briefly talk about some of themanufacturing difficulties, such as poor quality, associated with producing goods in a developing country.The best book relating to appropriate technology equipment used in developing countries is the ‘Appropriate Technology Sourcebook’ compiled by Darrow and Saxenian (1993). It is considered ‘The Bible’ by people in the appropriate technology field, such as those at CTI (Humphreys, 2005). The book is a resource listing appropriate technology machine books and papers that are available for purchase from other sources. It does not contain any designs of its own, but it does give a brief description of the contents of the papers and designs that are available for order. A search of this book and the updated website did not reveal any designs for manual shredders or grinders(/atnetwork/atsourcebook/index).Compatible Technology, InternationalCompatible Technology, International (CTI) () is an excellent local resource for dealing with appropriate technology in developing countries and has extensive connections throughout the world. It is an organization dedicated to using simple devices to improve food production and storage in the third world. They are a stakeholder in the design and development of the original shredder. The director of CTI is Bruce Humphreys who granted an interview on issues dealing with manufacturing in developing countries (2005). Some of the key points that he brought up were:Manufacturers in developing countries do not necessarily build parts to a fabrication print. Everything is custom and will look similar to what is desired,but is not quite the same.Creativity is not rewarded in many cultures and there is a desire to continue doing things the old way.Expectations in quality and standards will probably not be met. They do not typically produce to the same quality as is expected in the U.S.There are cultural norms and practices that will be slow to change and may not be overcome. This would primarily relate to the target market of women. Womentend to not use machines, thus the design must be easy to use and relatively toolfree.These assertions by Mr. Humphrey were reinforced in other literature relating to the topic (Obi, 1999).Hank Garwick and Dave Elton are the two CTI volunteers who are most closely tied into the Haiti mission. They have made several trips to Haiti on humanitarian missions associated with both CTI and the Methodist Church. The two offered insight into the Haitian mindset, manufacturing capabilities in Haiti, and experience in shredding breadfruit. Their comments on the manufacturing capabilities in Haiti were that “we would be lucky to find someone who could read a print, and even if they can they probably won’t follow it” (Garwick, 2005).Garwick and Elton were not satisfied with the work of the UST senior design team and continued to develop the shredder after the senior design team’s project ended. They made several small modifications to the design, built a prototype, and brought it down to Haiti to be tested (Fig. 4). The Garwick/Elton version of the shredder did not work as well as intended and did not produce the desired shred rate found by the UST engineering team (Garwick, 2005). It is unclear why this was the case. Several of the better design changes that they made to their shredder were incorporated into the current shredder design. These would include the sheet metal center divider and ideas on the retainer for the shredding blade.Figure 4: Garwick/Elton Breadfruit ShredderGarwick and Elton believed strongly that the prime power for the operation of the shredder should be a leg driven bicycle type mechanism instead of the current hand powered crank. Figure 5 shows a bicycle drive assembly that they added to a shredder (Garwick, 2005). This project is focused on producing a shredder for the poorest of people in Haiti and it was felt that a bicycle type mechanism would significantly add to the cost of the machine while making it unnecessarily complex. It is expected that this shredder will only be fully utilized for several weeks a year during the breadfruit harvest and would not justify the higher cost. The current design is one such that a bicycle type drive could be added to the shredder at a later date if desired by the user.Figure 5: Garwick/Elton Bicycle Drive MechanismInstitutional LibrariesThe United States Military Academy at West Point has an extensive library relating to military manuals and papers. The U.S. military routinely performs operations in developing countries and the units typically tasked with helping the local population are the Civil Affairs units and the Special Operations Forces. These units are often involved in nation building and community development and have close contact with the people. Daniel Prichard, a research librarian at the library, was contacted about any pamphlets, articles, or papers that the library may have on a shredder or appropriate technologies in developing countries. Mr. Prichard found nothing relevant at the Academy’s library (Prichard, 2004).A search of the University of St. Thomas’s and the University of Minnesota’s library systems found no books or on-site literature that was relevant to the design of the breadfruit shredder.Research and International OrganizationsThe Hawaiian Breadfruit Institute is an organization based in Hawaii whose mission is “to promote the study and use of Breadfruit for food and reforestation”( ). It tracks and propagates the 120 known varieties of breadfruit found on the islands of the Pacific Ocean and Caribbean Sea. Dr. Diane Ragone, director of the Hawaiian Breadfruit Institute, was contacted regarding the shredding of breadfruit and the possible existence of similar devices. Dr. Ragone responded that she had not heard of any similar processing methods for breadfruit. Her primary concern for this wasthat the latex found naturally in breadfruit would ‘gum-up’ the machine and clog the shredding blade (Ragone, 2005). This issue was raised with Hank Garwick of CTI and he stated that most of the latex in breadfruit was found in the skin. The skin is removed before processing so this did not appear to be a concern for the shredder. The field tests in St. Vincent by the senior engineering student team did not report any excessive latex build up on the blades.The International Research Development Centre (IRDC) is a Canadian based organization whose purpose is ‘to build healthier, more equitable, and more prosperous societies’ (www.irdc.ca ). An e-mail was sent to IRDC explaining the project and asking about any information that they might have on shredders. The response was a link to their website which brought up nothing of value. A similar search of the United Nations Development Program (UNDP) provided no additional information ().Research was done with the United States Food and Drug Administration (FDA) to see if there were requirements or recommendations for the food industry regarding food processing equipment or the components used in them. The purpose was to find out which materials were considered “Food Grade” and suitable for food contact. The goal is to make the shredder as sanitary and safe as possible regardless of the standards that may be present in a developing country. It was found that the FDA does not keep a list of recommended materials, but has established a list of requirements that manufactures must meet in order to state that it is a material approved for food contact. The premise of therequirements are that if any of the material could ‘migrate’ to the food, it must not pose a threat to humans (FDA, 1999).Expert InquiresThe Minneapolis/St. Paul area is home to several large food producing companies such as General Mills. Food Safety personnel at General Mills were contacted to ask about standards for their food production equipment and any suggestions that would help to make the shredder more sanitary and suitable for food contact. These inquiries covered guidelines that are typical of the food processing industry. Gary Olmstead, Food Safety Instructor at General Mills stated that equipment should be durable and easy to clean (Olmstead, 2005). General Mills avoids having any pieces of equipment over the product because of the risk of parts falling into the food. Fred Hegele, also part of food safety at General Mills, was concerned about the durability of any plastics used in the equipment. He emphasized that the machine cannot have any recessed pockets or hard to clean areas. These would trap bacteria and make it unsafe and unsanitary (Hegele, 2005). John Schevenius, a former General Mills Engineer and founder of CTI, was contacted about suggestions for the shredder. Although he was familiar with the breadfruit program, he could not offer any suggestions for improvement (Schevenius, 2005).The research done here showed that there is a lack of availability of information regarding the design of an appropriate technology machine. The design methodology varies from organization to organization and no standardized process appears to have been completed and published in a major journal regarding the topic. Appropriate。

MOUNT VERNON
No visit to Washington, D.C., is complete without a trip to Mount Vernon, the home of George Washington, our nation's illustrious first president. It is located just a few miles south of our nation's capital, and its fine views, spacious lawns, shaded walks, and carefully tended gardens make it one of the most popular tourist attractions in the nation. More than a million people a year visit Mount Vernon, where they may pay their respects to the memory of our first president and his wife, the first lady, both of whom are buried there.
Mount Vernon had been in the Washington family for almost a hundred years when George Washington inherited the property in 1761. It comprised five separate farms as well as the house overlooking the Potomac river in which he lived with his wife and her two children from a former marriage. Because the house was too small for their needs, Washington added rooms and outbuildings. He hired the best workers he could find and supervised their work closely; by the time he had finished, Mount Vernon was the fine mansion visitors see today.
Although Washington was loath to leave his beautiful home, his duty to his country required him to be absent from Mount Vernon from 1775 until 1783, while he was leading the Continental army in the war against the British. In his absence, a distant cousin, Lund Washington, managed the property for him. We know a great deal about this period in the history of Mount Vernon because the correspondence between the two men has survived.
Washington gave his cousin considerable latitude in looking after the estate, and Lund was a competent manager. However, one incident aroused Washington's wrath. Lund wrote to him saying that a British warship had come up the river and that the crew had asked for food. Not wanting to antagonize them, Lund had complied with their request. Washington reprimanded his cousin and told him that he should have refused "even if they had burnt my house and laid the Plantation in ruins."
In 1789, Washington reluctantly left Mount Vernon once again to serve as the country's first president. He retired from public life after eight years and returned for the last time to his beloved home, where two years later he died. The property remained in the Washington family until 1858, by which time the house was in a sadly dilapidated state. In that year, the Mount Vernon Ladies Association, a group of private citizens, acquired the property. The association carefully renovated the house so that it now looks as it did when George Washington lived there. The Mount Vernon Ladies Association has maintained it ever since and opens it to the public every day of the
year.。
