装 订 线 班级： 学号： 姓名： 第 6 页 共 6 页 A multimeter is a general-purpose meter capable of measuring voltage, , , and in some cases, decibels. There are two types of meters: using a standard meter movement with a needle (see Fig 3.1(a)), and , with an electronic numerical display (see Fig 3.1(b)). Both types of meters have a (+) jack and a jack (-) for the test leads， to select dc voltage, ac voltage, dc current, ac current, or ohms and for accurate readings. The meters may also have other jacks to measure (1 to 5 kV) and current (up to 10A) there are some variations to the functions used for specific meters. 1)Resistance 2)placed across (in parallel) 3)be removed 4)in series with 5)mechanical adjust 6)automatic indicator 5)properly 8) test leads 9)correct 10)be opened Besides the function and range switches (sometimes they are in a single switch.) The analog meter may have a polarity switch to facilitate reversing the test leads. The needle usually has a screw for to set it to zero and also a zero adjust control to compensate for weakening batteries when measuring . An analog meter can read positive and negative voltage by simply reversing the or moving the polarity switch. A digital meter usually has an for polarity on its display. Meters must be connected to a circuit to ensure a reading. A voltmeter is always the circuit or component to be measured. When measuring current, the circuit must and the meter inserted the circuit or component to be measured. When measuring the resistance of a component in a circuit, the voltage to the circuit must and the meter placed in parallel with the component.
三.Read the following passage and answer the questions.（5*8=40） Robots Robots produce mechanical motion that,in most cases,results in manipulation or locomotion.For example,industrial robots manipulate parts or tools to perform manufacturing tasks such as material handing,welding,spray painting,or assembly;automated guided vehicles are used for transporting materials in factories and warehouses.Telerobots provide astronauts with large mainipulators for remotely performing spacecraft maintenance. Robots perform repetitive,high-precision operations 24 hours a day without fatigue.Robots on this automobile assembly line weld body parts together.The General Motors corporation uses about 16,000 robots to weld,assemble,and paint automobiles. Walking robots explore active volcanoes.Mechanical characteristics for robots include degrees of freedom of movement,size and shape of the operating space,stiffness and strength of the structure ,lifting capacity,velocity ,and acceleration 第 5 页 共 6 页
under load.Performance measures include repeatability and accuracy of positioning,speed,and freedom from vibration. A robot is made up of sensors,actuators,and computatlonal elements(a microprocessor).Actuators for moving joints of a robot are usually electric servomotors.In the past ,larger robots were built with hydraulic actuation due to their high payload capacity and ability to work in explosion-prone environments.In the 1990s,there was a trend by the major manufacturers to use electric actuators in most of their industrial robots. A robot is an automatically controlled, reprogrammable, multipurpose, manipulating machine with several reprogrammable axes, which may be either fixed in place or mobile for use in industrial automation applications. The key words are reprogrammable and multipurpose because most single-purpose machines do not meet these two requirements. The term “reprogrammable” implies two things: The robot operates according to a written program, and this program can be rewritten to accommodate a variety of manufacturing tasks. The term “multipurpose” means that the robot can perform many different functions, depending on the program and tooling currently in use. Over the past two decades, the robot has been introduced into industry to perform many monotonous and often unsafe operations. Because robots can perform certain basic tasks more quickly and accurately than humans, they are being increasingly used in various manufacturing industries. 1.What industrial robots can do for people?

AMy wife, daughter, and I moved into our home nine years ago and we spent a lot of time and energy in the yard to get it looking like the way it does today. We live on a corner, higher than street level, and the entire side of the yard is surrounded by a professionally built rock wall. The front of the house though is another story because instead of a wall along the sidewalk, the rocks appear to be just thrown up onto the dirt as if someone were in a hurry to finish.We did the best we could with what we had to work with and called this area our “rock garden”. Whenever we had leftover flowers or plants, Denise or I would stick them out front, just to bring some color to the area. We would do all of the yard work on our own, even the tiring weed-pulling.Last summer I had reached the end of the rock garden and found a tiny little plant that I could not immediately identify, I knew I didn’t plant it and Denise claimed that she didn’t either. We decided to let it continue growing until we could figure out what it was.Weeks passed and as I made my way back to the mystery plant, it appeared to be aSunflower with a tall skinny stalk（茎，杆）and only one head on it. I decided to baby it along andweed around it. As I pulled rocks from the area to get to the weeds, I noticed something unusual. Array The Sunflower had not started where I saw the stalk begin. It actually had begun under a big rock and grown under and around it to reach the sun.That’s when I realized that if a tiny little Sunflower didn’t let a big rock stand in its wa y of developing, we too have the ability of doing the same thing. Once our environment begins to see that we believe in ourselves like that little Sunflower, we can attain the same nourishment（营养）and growth as well.Stand tall like the Sunflower and be proud of who and what you are and the environment will begin to support you. You will find a way to go under or around your big obstacle in order to reach your desires.1、We can know from the first paragraph that ______.A．the author finished building his home hurriedlyB．the author’s family have lived in this home for nine yearsC．the author’s home is made of rock wallsD．there is a wall along the sidewalk2、The author found it unusual that ______.A．the mystery plant turned out to be a SunflowerB．the Sunflower had a tall stalk and only one headC．the Sunflower grew under and around a big rockD．the Sunflower had started where the stalk was seen3、Which of the following best describes the Sunflower?A．Brave and stubborn B．Confident and persistentC．Optimistic and modest D．Mysterious and devoted4、What can be inferred from this passage?A．Human beings are able to remove obstaclesB．The universal truth made the sunflower surviveC．A big rock blocked out the sunlight of the sunflowerD．We can achieve success as long as we are self-confidentBOne evening at a busy crossroads, I noticed a sister struggling to keep her little kid under Array control while she talked on the pay phone. She wanted him to stay still next to her, but he wanted to run and play by the road, close to rushing buses and taxis. One could sense the woman’s frustration, that she was pulled in too many directions: She was angry at the person on the telephone and shouting at the younger that she would “snap（折断）his leg” if he moved again. As I waited for the traffic light to change, the child began to complain and struggle to free himself from the woman’s grasp. She dropped the phone, seized（抓住）the neck of his tiny. T-shirt and gave him a back-hand blow across the face that I know made his little head spin.The light changed, and passers-by continued on their way. But I stood there, fixed to the pavement. I knew this extremely upset woman would carry through on her threat of violence to the child. Before, I had wanted to get close to her and offer to watch the youngster while she dealt with the troubling situation on the phone. Now I wanted to comfort the little boy. I also wanted to speak to the sister to calm her and to caution（告诫）her, as I wish someone had cautioned me when I was passing my pain on to my daughter and causing her emotional suffering. But I was chicken. I thought, she may think I’m out of line, or I may be her next target.Oft en I’ve thought about that child and the many others abused（虐待）by adults. I wonder how they will internalize（使……藏在心底）their pain, and if it will crush their spirits. Will this little boy grow up to be an abusive man? Will he be gloomy（阴郁的，沮丧的）and withdrawn （孤僻，内向的）? Will he find it hard to communicate with women, with other men? Or will he survive and be sensitive, caring and determined not to continue the cycle?There is too much cruelty（残忍）in the world, too much cruelty between people. I tremble at the increasing verbal（言语的）bitterness and violence among Black girls, and among young mothers trying to discipline their children. This behavior isn’t class-or age-related: I hear sharp words from Black women from all walks of life who are overworked and stressed out and have grown impatient. At times I, too, become impolite to others, or, like the sister on the phone, strike out at（抨击）those closest to me.Often we’re tired because we've made the wrong choices. Young girls who still need mothering are loaded with ch ildren. We sisters easily get hurt and annoyed when we don’t compromise with our own sense of self. Our personal fulfillment requires knowing what is bestfor us, setting our boundaries（界限）and keeping them undamaged. We will always be asked todo more than we are comfortable doing. When we know our boundaries, we can decline Array comfortably. People—and we ourselves—will act in ways we don’t like. But they, like us, are still worthy of love.Whatever irritates（激怒）us about a person should be examined. Is the person reflecting behavior in us that needs to be changed? Often, when I find people irritating, I find they mirror something about me that I need to correct.What’s needed in our personal relationships is a return to gentleness and tolerance（容忍）. We must allow one another our learning experiences. Just as violence results to violence, verbal violence—the hard words and sharp tones we use to release inner stress—adds to the distance between us.What we people of African root must do to become, and continue to be strong begins with love, sensitivity and our ability to work together. We Black women have these spiritual resources in abundance（丰富）. Now we must encourage them to create a peaceful place—for ourselves, our children, our men.1、We can learn from the passage the mother of the little kid must be ________. A．frustrated and hot-tempered B．cruel and talkativeC．confused and quick-minded D．considerate and sensitive2、By saying “She may think I am out of line”, the author meant the woman might say ________. A．“You’re not standing in the queue.”B．“You can watch and comfort my kid.”C．“Walk away. It’s none of your business.”D．“You are walking in the wrong direction.”3、The wrong choices the author mentions in Paragraph 5 include ________.a. We sisters refuse to marry youngb. We aren’t satisfied with ourselvesc. We have our boundaries damagedd. We decline others’ requests for helpA．a, b B．c, dC．a, d D．b, c4、According to the author, when we find a person irritating, we should ________.A．return to gentleness and tolerance Array B．reflect on our behavior that needs correctingC．avoid the hard words and sharp tonesD．examine if anything is wrong with him第三部分语言知识运用（共两节）第一节（每小题1分，满分20分）阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项．The other day I was offered two tickets to a special preview of the latest movie for free. I wasn’t interested, 1 I knew my two boys would be.That evening, we were a bit 2 for time. So instead of having dinner at home, we had fast food near the movie theater Oscar. There went the 3 of eight movie tickets.Then I met up with a friend and we sat around 4 for a while , and another movie ticket went into a cup of coffee, After that, we figured we might as well 5 around until the movie ended to pick up the boys.

Read the passage and decide each of the statements is true or false, and mark a T for a true statement and an F for a false one.Passage 1Questions 1 to 5 are based on the following passage:Most people think of a camel as an obedient beast of burden, because it is best known for its ability to carry heavy loads across vast stretches of desert without requiring water. In reality, the camel is considerably more than just the Arabian equivalent of the mule. It also possesses a great amount of intelligence and sensitivity.The Arabs assert that camels are so acutely aware of injustice and ill treatment that a camel owner who punishes one of the beasts too harshly finds it difficult to escape the camel’s vengeance. Apparently, the animal will remember an injury and wait for an opportunity to get revenge.In order to protect themselves from the vengeful beasts, Arabian camel drivers have learned to trick their camels into believing they have achieved revenge. When an Arab realizes that he has excited a camel’s rage, he places his own garments on the ground in the animal’s path. He arranges the clothing so that it appears to cover a man’s body. When the camel recognizes its master’s clothing on the ground, it seizes the pile with its teeth, shakes the garments violently and tramples on them in a rage. Eventually, after its anger has died away, the camel departs, assuming its revenge is complete. Only then does the owner of the garments come out of hiding, safe for the time being, thanks to this clever ruse.1. ( ) The camel is more than an obedient beast of burden.2. ( ) The camel is insensitive but vengeful.3. ( ) Camels are generally vicious towards their owners.4. ( ) When an Arab realizes that he has excited a camel’s rage, he’d better channel it toescape the camel’s revenge.5. ( ) It is dangerous to keep a camel as a domesticated animal.Section BDirections:In this section there are two passages followed by ten questions, each with four suggested answers marked A, B, C and D. Choose the ONE that you think is the best answer.Passage 2Questions 6 to 9 are based on the following passage:The destruction of our natural resources and contamination of our food supply continue to occur, largely because of the extreme difficulty in affixing legal responsibility on those who continue to treat our environment with reckless abandon. Attempts to prevent pollution legislation, economic in-centimes and friendly persuasion have been met by lawsuits, personal and industrial denial and long delays--not only in accepting responsibility, but more importantly, in doing something about it.It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative for change. Where is industry’s and our recognition that protecting mankind’s great treasure is the single most im portant responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now.We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge.We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer afford to be tunnel-versioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion. I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can accomplish these three goals in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages.6. We can infer from the first two paragraphs that the industrialists disregard environmental protection chiefly because _____.A. They are unaware of the consequences of what they are doing.B. They are reluctant to sacrifice their own economic interests.C. Time has not yet come for them to put due emphasis on it.D. It is difficult for them to take effective measures.7. The main task now facing ecologists, environmental activists and conservationists is _____.A. to prevent pollution by legislation, economic incentives and persuasionB. to arouse public awareness of the importance of environmental protectionC. to take radical measures to control environmental pollutionD. to improve the quality of life by enforcing environmental standards8. The word tunnel-versioned (Line 2, Para.4) most probably means ____.A. narrow-mindedB. blind to the factsC. short-sightedD. able to see only one aspect9. Which of the following, according to the author, should play the leading role in the solution of environmental problems?A. Legislation and government interventionB. The industry's understanding and supportC. The efforts of environmental health professionalsD. The cooperation of ecologists, environmental activists and conservationistsPassage 3Questions 10 to 14 are based on the following passage:Locusts, which can consume their own weight in food each day, have a large neuron called the locust giant movement detector (LGMD) located behind their eyes. The LGMD releases bursts of energy whenever a locust is on a collision course with another locust or a predatory bird.A few years ago Rind and her colleagues studied the activity of the LGMD as locusts watched action scenes from the movie Star Wars. The team found that the LGMD releases more energy when something is coming directly at the locust.These spikes of energy, called action potentials, prompt the locusts to take evasive action. The entire process from motion detection to reaction takes about 45 milliseconds--or 45 thousandths of a second.“Locusts, like most insects, can see many more images per second than we do. This means they can react in time to things that are approaching very rapidly and so make their escape before collision,” Ring said.The locusts’ ability to see many more images per second than humans gives them a remarkable view of the world. For humans, it would be like watching everything go by in slow motion, Rind added.And because the insects only detect things that are on a collision course with them, the locusts are ignorant of all other movements. It’s a particularly useful trait, as the locusts travel in dense swarms akin to rush hour traffic.“The (LGMD) system is complemen ted by the brain of the locust, which provides the necessary experience and knowledge to really react according to the situation,” said Jorge Cuadri, a project engineer with Spain’s National Center of Microelectronics. Cuadri is helping to develop the circuitry for the locust-inspired crash avoidance technology.Cuadri and his colleagues are responsible for adapting the locust collision-avoidance system to the automotive environment.Their adapted system is based on a single, integrated step that combines visual optics and electronics. The conventional way of doing this would involve two steps: First, a camera would capture the image. Second, a digital processor would analyze it.The two-step approach, which uses radar images, is expensive and currently limited only to luxury cars, Rind said.（357 words）10. One of the reasons why human beings are unable to react in time to avoid car collisions themselves is that _____.A. They have no LGMD behind their eyes.B. Cars are not advanced enough yet.C. Their visual is too limited.D. Their brain is never good at functioning in this way.11. What would immediately happen if human beings were endowed with the power to seea good many images in quite a short instant?A. Every movement would become so easily observable that it is just like in slow motion.B. Human beings would be ignorant of all other movements except things that are on a crash route with them.C. Everything around would pass by at a lower speed.D. Human beings would be very sensitive to those cars that are about to bump.12. In the 7th paragraph, what does “complement” mean here?A. CombineB. ExtendC. ExpandD. Complete13. What kind of field is covered when Cuadri adapts the locust collision-avoidance system to the automotive environment?A. Visual optics and electricsB. Electronics and visual opticsC. Visual optics and visual electronicsD. Physics and chemistry14. The passage will most probably be followed by a discussion of _____.A. how to decrease the price of this adapted systemB. how to derive new methods from other insectsC. what problems researchers would face and the future development of crash-avoidancecircuitryD. the further analysis of LGMDSection CDirections: In this section there are two passages followed by nine questions. Answer each question with one or more statements.Passage 4Questions 11 to 15 are based on the following passage:Imagine a world in which there was suddenly no emotion--a world in which human beings could feel no love or happiness, no terror or hate. Try to imagine the consequences of such a transformation. People might not be able to stay alive: knowing neither joy nor pleasure, neither anxiety nor fear, they would be as likely to repeat acts that hurt them as acts that were beneficial. They could not learn: they could not benefit from experience because this emotionless world lacks rewards and punishments. Society would soon disappear: people would be as likely to harm one another as to provide help and support. Human relationships would not exist: in a world without friends or enemies, there could be no marriage affection among companions, or bonds among members of groups. Society's economic underpinnings would be destroyed: since earning $10 million would be no morepleasant than earning $10, there would be no incentive to work. In fact, there would be no incentives of any kind. For as we will see, incentives imply a capacity to enjoy them.In such a world, the chances that the human species would survive are next to zero, because emotions are the basic instrument of our survival and adaptation. Emotions structure the world for us in important ways. As individuals, we categorize objects on the basis of our emotions. True, we consider the length, shape, size, or texture, but an object's physical aspects are less important than what it has done or can do to us--hurt us, surprise us, anger us or make us joyful. We also use categorizations colored by emotions in our families, communities, and overall society. Out of our emotional experiences with objects and events comes a social feeling of agreement that certain things and actions are "good" and others are “bad”, and we apply these categories to every aspect of our social life--from what foods we eat and what clothes we wear to how we keep promises and which people our group will accept. In fact, society exploits our emotional reactions and attitudes, such as loyalty, morality, pride, shame, guilt, fear and greed, in order to maintain itself. It gives high rewards to individuals who perform important tasks such as surgery, makes heroes out of individuals for unusual or dangerous achievements such as flying fighter planes in a war, and uses the legal and penal system to make people afraid to engage in antisocial acts.15. Why might people not be able to stay alive in a world without emotion?16. According to the passage, why are people’s learning activities are possible in an emotional world?17. According to the passage, what is the economic foundation of society dependent on?18. Why are emotions significant for man's survival and adaptation?Passage 5Questions 19 to 23 are based on the following passage:Most growing plants contain much more water than all other materials combined. C. R. Barnes has suggested that it is as proper to term the plant a water structure as to call a house composed mainly of brick a brick building. Certain it is that all essential processes of plant growth and development occur in water. The mineral elements from the soil that are usable by the plant must be dissolved in the soil solution before they can be taken into to the root. They are carried to all parts of the growing plant and are built into essential plant material while in a dissolved state. The carbon dioxide(二氧化碳）from the air may enter the leaf as a gas but is dissolved in water in the leaf before it is combined with a part of the water to from simple sugars--the base material from which the plant body is mainly built. Actively growing plant parts are generally 75 to 90 percent water. Structural parts of plants, such as woody stems, due to longer actively growing, may have much less water than growing tissues.The actual amount of water in the plant at any one time, however, is only a very small part of what passage through it during its development. The processes of photosynthesis (光合作用), by which carbon dioxide and water are combined--in the presence of chlorophyll (叶绿素）and with energy derived from light-to from sugars, require that carbon dioxide from the air enter the plant. This occurs mainly in the leaves. The leaf surface is not solid but contains great numbers of minute openings, through which the carbon dioxide enters. The same structure that permits the one gas to enter the leaf, however, permits another gas-water vapor--to be lost from it. Since carbon dioxide is present in the air only in trace quantities (3 to 4 parts in 10,000 parts of air) and water vapor is near saturation in the air only in the air spaces within the leaf at 80°H, saturated air would contain about 186 parts of water vapor in 10,000 parts of air), the total amount of water vapor lost is many times the carbon dioxide intake. Actually, because of wind and other factors, the loss of water in proportion to carbon dioxide intake may be even greater than the relative concentrations of the two gases. Also, not all of the carbon dioxide that enters the leaf is synthesized into carbohydrates (碳水化合物).19. What does a growing plant need water for?20. What is the essential function of photosynthesis in terms of plant needs?21. What is the essential idea the second paragraph use facts to develop?22. How does carbon dioxide enter the plant?23. What factors result in the total amount of water vapor lost is many times the carbon dioxide intake?Part IV Summary Writing (15 points)Direction:There is one passage in this section.Read the passage and write a summary of it within 150 words.Those who distrust pills will take satisfaction in recent news from America’s National Institute of Health. On January 18th the NIH announced the results of two studies of the effects of taking vitamin A and beta-carotene (which the body turns into vitamin A) pills, both widely believed to protect people against lung cancer. For pills taker, the news was bad.In neither study did the pills live up to people’s expectations. In the mixed-sex testing, in fact, those who were given dummy pills that looked like the vitamin pills go on rather better — developing 28% fewer lung cancers — than those who took the real thing. Besides that, the death rate of the real vitamin takers was 17% higher from all causes and 26% higher from heart and blood-vessel diseases than that of the control group. All those showed no strong influence either way from taking vitamin pills.Taken together, the two studies suggest that non-smokers have nothing to gain from adding vitamin A or beta-carotene pills to their diets. For smokers and people at high risk for other reasons their use may be dangerous. Much the same conclusion emerged from an earlier study published in 1994, of nearly 30,000 male smokers in Finland. Here, the men who took beta-carotene pills daily for between five and eight years developed 18% more lung cancers and had a death rate 8% higher than the controls.With all this bad news, the cautious might be tempted to keep away from peaches,pumpkins, carrots and other natural sources of beta-carotene, as well as from pills. But they should not do so, in the opinion of Richard Klausner, director of the NIH’s National Cancer Institute.Population studies, he noted, have linked high dietary intake of beta-carotene in vegetables and fruit to a reduced risk of cancer, and in particular lung cancer. That, after all, is what got people excited about the stuff in the first place. But food rich in beta-carotene would seem to have additional, as-yet-unknown elements that help discourage the abnormal cell growth characteristic of cancer. The absence of these extra elements is likely to explain the failure of the beta-carotene and vitamin A pills to provide the same protection.英语阅读II 考试试卷A答题纸适用于考试日期：；试卷所需时间：120分钟； 闭卷； 总分：100分。
