Read the passage carefully and fill in each of the blanks by choosing the right word or phrase from thelist given below. Write your answer on the Answer Sheet II. Capitalize theword when it is necessary. The words and phrases listed are twice as manyas the blanks. Once a word or phrase is chosen, it must be used only once.Many of the most damaging and life-threatening types of weather—torrential rains, severe thunderstorm, and tornadoes—began quickly, strike suddenly, and dissipate rapidly, devastating small regions 21 leaving neighboring areas untouched. One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado 22 $ 250 million, the highest 23 for any Canadian storm. Conventional computer models of the atmosphere have limited value in predicting short-lived local storms 24 the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that 25 these storms. In most nations, for example, weather-balloon observations are taken just 26 every twelve hours at locations typically 27 by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions 28 they do forecasting specific local events.Until recently, the observation—intensive approach needed for accurate, very short-range forecasts, or “Nowcast”, was not 29 . The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. 30 , scientific and technological advances have 31 most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly 32 observations over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and 33 , and modern computers can quickly compile and analyze this large volume of weather information. Meteorologists and computer scientists now work3together to design computer programs and video equipment capable of 34 raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. 35 meteorologists have begun using these new technologies in weather forecasting offices, nowcasting is becoming a reality.Section B (20 questions×1.5 points= 30 points)Directions: Read the following passages carefully and then select the best answer from the four choices given to answer each of the questions or complete each ofthe statements that follow each passage. Mark the letter of your choice onyour Answer Sheet I.Passage 1For centuries, the gravel and sand of Georges Bank and the great canyons, muddy basins, and shallow ledges of the Gulf of Maine have supported one of the world’s most productive fishing regions. But big boulders have historically protected a 1050-square-kilometer region at the bank’s northeastern tip from dredging boats in search of scallops and trawlers hunting down groundfish. However, those boulders are becoming less of a deterrent against improved and sturdier gear. So when geologist Page Valentine of the U.S. Geological Survey in Woods Hole, Massachusetts, stood before his colleagues last month and defended his proposal to safeguard this rare, undisturbed gravel bed, he knew that he was also standing at the crossroads of science and politics. Valentine’s presentation was part of a 2-day workshop held at the New England Aquarium here to build support for Marine Protected Areas (MPAs), a controversial concept aimed at preserving biodiversity in coastal waters. The meeting, organized by Elliott Norse, founder of the Marine Conservation Biology Institute in Redmond, Washington, featured talks by 21 experts across a range of marine habitats and species and represented the marine community’s biggest push fo r MPAs.The discussion generated a map that nominated 29% of the ocean floor off the coast of New England and Canada’s Maritime Province for protection, as well as 25% of pelagic (open-ocean) waters. The next step will come in the fall, when the scientists discuss the plan with government officials, commercial stakeholders, and environmental activists—meetings that are likely to be contentious. “The conservation groups will want to see if various species are covered. And various fishermen will be convinced that their livelihood is threatened,” says Mike Pentony, an analyst for the New England Fishery Management Council, who was an observer at last month’s workshop. The areas could be established by the National Marine Fisheries Service or under existing U.S. and Canadian laws to protect endangered species and habitats.36. Which of the following can be the best title of the passage?A.Fishery Industry in New England.B.Plan to Protect Coastal waters of New England.C.Restoration of Marine Life in the Gulf of Maine.D.Problems Critical to Ecological Balance in Georges Bank.37. The abundance of fish in the area has been a result of ________.A.the perpetual fishery closureB.the stringent ban on overfishingC.the effective fishery management4D.its unique geographic features38. Boulders used to be a deterrent to ________.A.scallopB.groundfishC.fishing boatsD.improved gear39. At the two-day workshop, the scientists reached an agreement on ______.A.the marine areas to be preservedB.how to rescue the endangered speciesC.the guarant ee of the fishermen’s livelihoodD.what to discuss with the government officials40. Which of the following CANNOT be concluded from the last paragraph?A.The fishermen will be worried about their livelihood.B. A decision is soon to be made on the protected areas.mercial stakeholders may be at odds with scientists.D.Conflicting interests will arise between fishermen and scientists.Passage 2Some people are accustomed to thinking that facts must either be believed or they must be disbelieved—as if beliefs were like a light switch with only two positions, on or off. My use of the bathtub hoax is intended to illustrate that belief does not have to operate as a simple yes or no choice, all or nothing. Belief can be more conditional; it can be something that we d ecide to have “up to a point.” And so, the question we might ask ourselves while reading does not have to be “Should I believe it or not?” but instead can be “How much should I believe it?” This later question implies that the belief we have in any given fact, or in any given idea, is not determined by whether it sounds right or whether the source is an authority. It means that our beliefs are determined by the reasons that justify them. Belief is not a mechanical action, brought about by invariable rules of nature. It is a human activity, the exercise of judgment. With this in mind, we might say that we perform this action better when we know what the reasons are that have led to our belief, and why they are good reasons.These observations do not deprive us of our ability to believe in what we read. They are not intended to transform you from credulous believers into stubborn doubters. The process of weighing beliefs against the quality of reasons is one that you already go through all the time, whether you are aware of it or not. We all do. The practice of critical reading is the exercise of this kind of judgment on purpose. By doing it, we protect ourselves from being led into belief for inadequate reasons, but at the same time we open up our minds to the possibility of arriving at belief for adequate ones. If we decide to grant or withhold consent based on the quality of the reasons that we are given we admit at the same time that two things are possible: We admit that we might consent less in the future if we discover that the reasons are not so good after all; and we admit that we might consent more if we are ever presented with better reasons than we had formerly known. This attitude is not pure skepticism any more than it is pure credulity. It is somewhere in between. It is the attitude of an open-minded thinker, of someone who wishes to be responsible for deciding for herself or himself what to believe.541. The author’s use of the bathtub hoax is meant to suggest that __________.A. facts must be believed unconditionallyB. belief is more than a simple yes or no choiceC. nothing should be believed or disbelievedD. belief is nothing but a light switch42. To believe or disbelieve what you read should be based on ________.A. the facts that you are givenB. whether the author is an open-minded authorityC. the quality of reasons provided by the materialD. the assumption that you know everything about it43. As a human activity, weighing the facts about something is actually _______.A. determined by the rules of natureB. a performanceC. brought about even at birthD. experienced by everyone44. According to the author, which of the following is true?A. Our attitude toward what we read may change if we are given better reasons.B. An open-minded thinker is responsible for what he or she says.C. Critical reading can make us believe more in what we read.D. We ought to question the value of what we read if its source is not authoritative.45. What is the topic of this passage?A. Judgment and Responsibility.B. Reading and Belief.C. Trust and Faith.D. Reading and Human Activity.Passage 3Things don’t come easily to Matteo, a 4-year-old New Yorker with brown bangs and cowboy bandanna. Afflicted by cerebral palsy, he moves awkwardly. He thinks slow ly and doesn’t talk much. Small frustrations upset him terribly. But when Matteo visits Clive Robbins, his music therapist, he bangs gleefully on a snare drum, placing one hand on the rim to steady himself, he uses the other to rap in tempo to Robbins’s improvised song. As the tune progresses, Matteo moves his act to the piano, banging along with one or two fingers and laughing excitedly. By following the rhythm, he is learning to balance his body and coordinate the movement of his limbs. He’s also learning to communicate. “He is grown much more motivated and intent,” says Robbins, the co-founder of New York University’s Nordoff-Robbins Center for Music Therapy.Disabled children aren’t the only ones feeling the therapeutic power of music. A 79-year-old stroke survivor listens to Viennese waltzes on his headphones to help him to relearn to walk. A woman in labor had LeAnn Rimes’ country tunes blaring from a stereo to help her keep in step with her contraction. And, yes, ostensibly healthy people are listening to airy New Age discs, and maybe lighting a candle or two, to lessen stress and promote well-being. They may all be on to something. Mounting evidence suggests6that almost any musical stimulus, from Shostakovich to the Spice Girls can have therapeutic effects.Music therapy isn’t mainstream health care, but recent studies suggest it can havea wide range of benefits. In 1996, researchers at Colorado State University tried giving10 stroke victims 30 minutes of rhythmic stimulation each day for three weeks. Compared with untreated patients, they shared significant improvements in their ability to walk steadily. People with Parkinson’s disease enjoyed similar benefits. A musical beat from any genre seemed to provide a rhythmic cue, stimulating the brain’s mot or systems.Other body systems seem equally responsive. Scottish researchers have found, for example, that a daily dose of Mozart or Mendelssohn significantly brightens the moods of institutionalized stroke victims. Using psychological tests, the Scottish team showed that patients receiving 12 weeks of daily music therapy were less depressed and anxious, and more stable and sociable, than other patients in the same facility. Music therapy has also proved useful in the management of Alzheimer’s and other neu rological diseases. And Deforia Lane, a music therapist at University Hospitals in Cleveland, has shown that music can boost immune function in children. That’s consistent with a 1995 finding by Louisiana researchers that preemies exposed to lullabies in the hospital went home earlier.46. Which of the following would be the best title for this passage?A.Why Music is PowerfulB.Music and Pain MedicationC.Music and Disabled ChildrenD.The Medical Power of Music47. What does the passage say about Matteo?A. He is suffering a paralysis of the brain.B. He is late in his ability to walk and talk.C. He plays music better by taking the advice.D. He’s ambitious to become a professional drummer.48. Paragraph 2 mainly tells that ________________.A.music helps pregnant women undergo contractionsB.music stimulates promotion of people’s well-beingC.music seems to have therapeutic effects on all peopleD.sick people benefit a lot from listening to music49. By mentioning the Spice Girls, the author gives an example of musicA.which is popular among children.B.which is good for health.C.which may harm one’s health.D.which is losing popularity.50. According to the context, the word “preemies” probably means________.A.sick children coming to see a doctorB.children with infectious diseasesC.newly recovered young patients7D.premature babiesPassage 4In terms of lives lost and property destroyed, the Civil War was the most terrible armed conflict Americans have ever known, but that has not prevented them from remembering it with enduring fondness. The Civil War remains the most written-about period in American history, and it provides boundless entertainment in the United States and around the world. Instead of an object lesson in the dangers of political polarization, racial inequality, and human cruelty, fans consider their favorite war an exercise in nobility—a bloodbath that somehow forged the unbreakable bonds of American national identity.Most Civil War historians were reared in this romantic tradition, and they have yet to fully free themselves from it. They still view the struggle through rose-colored glasses, making excuses for flawed heroes who have the reputations they never deserved. With the publication of While in the Hands of the Enemy: Military Prisons of the Civil War, Charles W. Sanders has distinguished himself as one of the few scholars capable of addressing the Civil War with utter frankness. His brilliantly researched book is a ringing indictment of the prisoner-of-war (POW) systems maintained by both sides of that war, as well as the politicians and soldiers who deliberately sent thousands of men to needless suffering and death. There are no heroes in this study, just too many unnecessary victims.Sanders sets his study in context by first tracing the evolution of POW policy during the American Revolution, War of 1812, and Mexican War. Americans knew that POWs were vulnerable to mistreatment, and the quickest way to improve their lot was to negotiate exchanges with the enemy. At the outset of the Civil War, neither side was prepared to cope with the many foes their armies captured, and prisoners inevitably suffered from inadequate housing, food, medical care, and other necessities. Abraham Lincoln delayed the implementation of general exchanges until July 1862 for fear it would allow rebellious southerners to claim de facto recognition of the Southern sovereignty. Once implemented, the exchange system quickly emptied prisons in the North and South, but it began breaking down by the end of the year.51. Most Civil War historians would agree that the Civil War may haveA. taught a useful lesson about human nature.B. started political struggles in America.C. raised the awareness of the race issue.D. strengthened American national identity.52. Civil War historians usual ly believe that “flawed heroes”A. should be forgiven.B. should be criticized.C. should be studied further.D. should be evaluated objectively.53. According to Charles W. Sanders, the Civil WarA. created various heroes.B. brought pointless misery.C. started the first POW system.8D. was brutal but inevitable.54. In the early days of the Civil War,A. the POWs were in difficult situations.B. the number of the POWs was small.C. the POW exchanges were frequent.D. both sides used the POWs for political purposes.55. What does the passage say about the POW exchange system of 1862?A. It had been postponed deliberately.B. It put the South at a political advantage.C. It became a successful model for later time.D. It raised the public awareness of the POW problem.Section C (10 points)Directions: There are two passages in this section. In each of the passages, five sentences have been removed from the original text. They are listed from A toF and put below the passage. Choose the most suitable sentence from the listto fill in each of the blanks numbered 56 to 60 and 61 to 65. There is onesentence that does not fit in any of the blanks. Mark your answers on yourAnswer Sheet I.Passage 1China’s growth is not uniformly high. Like every other e conomy in the world, China’s is shaped by its geography, in this case an east-west divide and a north-south divide. ___56___ China’s east coast is the Pacific Ocean, and some of the most important port cities in the world can be found there, including (from north to south) the ports of Tianjin, Shanghai, Guangzhou, Hong Kong, and Hainan Island. The coastal provinces have the advantage of proximity, both in time and transport costs, to major world markets by sea-based trade. ___57___ Both are forbidding borders, with enormous transport costs and great distances to major world trading centers. It is not surprising that the western provinces have been growing much less rapidly than the eastern provinces, and that foreign investors focus their investments almost entirely on the eastern coastal provinces____58____ This is economic geography, and the east-west growth divide is natural. It won’t go away. It will be addressed partly through an internal migration of job seekers leaving the west and heading east. This trend has already produced the largest migration occurring in the world today, with perhaps 150 million people having moved either permanently or seasonally between the interior and the coastal provinces. ___59___ These investments will help improve infrastructure, industrial development, and social development, through better schools and better health services.The Chinese north-south divide is a little bit less conspicuous, but it is also very significant. The north is dry compared to the south. ___60___ Already China is talking about spending tens of billions of dollars to divert rivers from the south to the north in three great canals whose costs, effectiveness, and ecological effects are hard to assess with precision, but the risks are very large.910Passage 2Doctors have long known that lung cancer, which kills 160,000 Americans each year, takes a heavier toll among black Americans, particularly black men, than among whites. ___61___ It also has to do with differences in income and access to medical care. But there has always been a lingering suspicion that some of the gap might be due to either overt or subconscious discrimination. A study in last week’s New England Journal of Medicine appears to support that disturbing conclusion.___62___ Even so, about 20% of lung-cancer patients are found to have a tumor whose biological characteristics and small size give them a good chance of being cured if the malignant growth is surgically removed.Researchers at the Memorial Sloan-Kettering Cancer Center in New York City and the National Cancer Institute in Bethesda, Md., looked at data from more than 10,000 white and black Medicare patients whose tumors were found early enough to make them candidates for surgery. About 77% of the white patients underwent the procedure, compared with 64% of blacks. The difference was sufficiently large to reduce the overall survival rate for black patients to 26% after five years, compared with 34% for whites. ___63___ “People are dying needlessly,” says Dr. Peter Bach of Memorial Sloan-Kettering,who led the study. He suspects “some combination of the procedure not being offered or pushed by doctors, and patients not accepting it.”___64___ So getting the word out that there is a proven treatment could help close the gap. It’s also vital for doctors and patients to make sure they understand each other.Better communication will be even more important as treatments become more complex . Currently there’s no screening test for finding lung cancer early. (Chest X rays almost always catch it too late.) But Dr. Claudia Henschke of the Weill Medical College at Cornell University in New York City and her colleagues believe they have found a way to identify very small tumors with low-dose CAT scans. ___65___PAPER TWOSection A (10 points)Directions:Read the following article and write a summary of between 120 and 150 words on your Answer Sheet II. You should NOT copy the original sentences This year, like every other year within the past couple of decades, uncountable trillions of mosquitoes will inject malaria parasites into human blood streams billions of times. Some 300 to 500 million full-blown cases of malaria will result, and between 1 and 3 million people will die, most of them pregnant women and children. That’s the official figure, anyway, but it’s likely to be a substantial underestimate, since most malaria deaths are not formally registered, and many are likely to have escaped the estimators. Very roughly, the malaria death toll rivals that of AIDS, which now kills about 3 million people annually.But unlike AIDS, malaria is a low-priority killer. Despite the deaths, and the fact that roughly 2.5 billion people (40 percent of the world’s population) are at risk of contracting the disease, malaria is a relatively low public health priority on the international scene. Malaria rarely makes the news. And international funding for malaria research currently comes to a mere $150 million annually. Just by way of comparison, that’s only about 5 percent of the $2.8 billion that the U.S. government alone is considering for AIDS research in the next fiscal year.The low priority assigned to malaria would be at least easier to understand, though no less mistaken, if the threat were static. Unfortunately it is not. It is true that the geographic range of the disease has contracted substantially since the mid-20th century, but over the past couple of decades, malaria has been gathering strength. Virtually all areas where the disease is prevalent have seen drug-resistant strains of the parasites emerge—a development that is almost certainly boosting death rates. In countries as various as Armenia, Afghanistan, and Sierra Leone, the lack or deterioration of basic infrastructure has created a wealth of new breeding sites for the mosquitoes that spread the disease. The rapidly expanding slums of many tropical cities also lack such infrastructure; poor sanitation and crowding have primed these places as well for outbreaks—even though malaria has up to now been regarded as predominantly a rural disease.What can current policy offer in the face of these threats? The medical arsenal is limited; there are only about a dozen anti-malarial drugs commonly in use, and there is significant malaria resistance to most of them. In the absence of a reliable way to kill the parasites, policy has tended to focus on killing the mosquitoes that bear them. And that has led to an abundant use of synthetic pesticides, including one of the oldest and most dangerous: dichlorodiphenyl trichloroethane, or DDT.11Section B (15 points)Direction:Now China has a growing number of old people. How will this trend affect China? Write an English essay of at least 200 words to explain your answer.

The B/L is marked “freight paid” and “free out”, would this be acceptable3.an L/C calls for FOB shipment and B/L marked “freight collect”, the B/L is marked “freight collect” and “free in”, would this be acceptable4.an L/C calls for an ocean B/L and delivery on FOB terms. Would a B/L be acceptable if marked “freight payable as per charter party”5.an L/C calls for an AWB showing “actual flight date”. When received, the AWB shows this information but in a box marked “for carrier’s information only”. Would this be acceptable6.under “documents required”and L/C lists both “certificate of origin” and “GSP form A”. only the latter document is presented by the beneficiary. Would this be acceptable7.an L/C calls for a certificate regarding the vessel “to be issued by the carriers”. The B/L has been issued by Borneo Shipping Pte Ltd as agents for the carrier, Nyk Line. Borneo Shipping has also issued the certificate as agents for Nyk Line. Would this be acceptable8.an L/C calls for presentation of a copy telex/fax to the applicants giving certain information. The document presented is the beneficiary’s signed certificate that they have sent such a telex to the applicant (the certificate also lists the information sent which is accurate and complete). Would this be acceptable9.an L/C calls for “commercial invoice”, when presented, the invoice, which has been computer-generated, is not marked “original”, it does however bear an original manual signature. Would this be acceptable10. A beneficiary presents documents within the expiry date of the L/C but they contain discrepancies. The beneficiary collects the offending documents for correction (leaving the rest with the bank) and in due course presents correct documents, however, in the interim the L/C has expired. Should the bank now reject the documents for “credit expired”11.an L/C (which allows transshipment) calls for shipment from a UK airport. The AWB shows goods on a flight from Paris to London then transshipment to another flight from London to the ultimate destination as specified in the L/C. would this be acceptable12.an L/C issued in favour of a beneficiary in Galle, Srilanka calls fora certificate of origin issued by the “local chamber of commerce”, whenpresented it has been issued by the chamber of commerce in Colombo, srilanka. Would this be acceptable13.an L/C calls for ocean shipment from “western Europe to south korea”. In full utilization of the L/C, the documents presented include 3 sets of ocean B/L all showing the same vessel/voyage but 3 different ports of loading (all within western europe) and 3 different ports of discharge (all in south korea). Does this constitute evidence of partial shipment14.an L/C subject to UCP600 specified that the L/C number must be quoted in all documents presented. The commercial invoice did not quote the L/C no. and issuing bank refused payment. Is the issuing bank correct in its refusal15.is the following invoice acceptable or notDescription of the goods in an L/C is: 1000 pieces of towelsL/C amount: USD1000Invoice presented shows: Towels: 1000 piecesTotal value: USD 1000Samples of cap: 20 free of chargePart Four 判断正误1.Having transferred the full shipment/expiry dates and presentation period and made the L/C available in the transferee’s country, the first beneficiary cannot now substitute documents after the L/C has expired or late presentation occurred.2.part shipments/drawings are prohibited unless otherwise stated in the L/C.3.unless otherwise stated in the L/C, transport documents must show the L/C beneficiary as shipper/ consignor.4.an L/C calls for invoices in triplicate. When presented, they are identical computer-generated documents none of which is marked original. However, this is acceptable as the L/C only stated triplicate, not original and two copies.5.an insurance policy is acceptable in lieu of an insurance certificate and vice versa.6.according to article 13 of UCP600, if the credit stipulates that a claiming bank must supply a certificate of compliance with the terms and conditions of the credit when making reimbursement claim, the reimbursing bank can disregard such a stipulation.7. a bill of lading with pre-printed wording to show that the goods have been loaded on board can simultaneously bear a dated on-board notation. In such a case the date of the on-board notation will be deemed to be the date of shipment whether it is earlier or later than the issuance date or the two are the same.8.if the bill of lading indicates a place of receipt or taking in charge different from the port of loading, the on board notation must also include the port of loading stipulated in the credit and the name of the vessel on which the goods have been loaded, even if they have been loaded on the vessel named in the bill of lading. This provision does not apply when loading on board thevessel is indicated by pre-printed wording on the bill of lading.9.terms such as “first class”, “well-known”, “independent”, “local”, “official”, “qualified”, “competent”and the like are ambiguous words in light of the UCP. If such terms are incorporated in the credit, banks will accept the relative document (s) as presented, provided that it appears on its face to be in compliance with the other terms and conditions of the credit.10.as for a charter party bill of lading, banks will not examine the charter party contract to which the bill of lading is subject. But if the credit requires beneficiary(ies) to present the contract along with other documents banks have to determine whether it is in compliance with the terms and conditions of the credit.11.under a freely negotiable and transferable credit any bank except the issuing bank is a nominated bank. Now that the relative article of UCP600 sets a rule that only the nominated bank has the right to make the transfer, thereof any bank exclusive of the issuing bank can transfer such a credit unless otherwise stipulated.12.without the agreement or authorization of the applicant, an issuing bank must issue a credit strictly as what the application says and cannot make any alteration even if to supplement or develop the terms in a manner necessary or desirable to permit the use of the credit.13.if a signature and/or endorsement is required to be on a document consisting of more than one page, the signature is normally placed on the first or last page of the document, but unless the credit or the document itself indicates where a signature or endorsement is to appear, the signature or endorsement may appear anywhere on the document14.if an L/C requires “invoice”or “one invoice”it will be understood to be a requirement for an original invoice. If an L/C requires “invoice in 1 copy”, it will be understood to be a requirement for a copy of an invoice.15.an L/C called for one copy of insurance certificate, the original to be sent to the applicant by the beneficiary outside the L/C. the beneficiary presented one original in place of one copy. The original indicated on its face in column: NUMBER OF ORIGINAL: ONE. The presentation is valid.16.description of goods: 100 tables, unit price: USD100 FOB shenzhen, total value: USD10000 partial shipment alloweddescription of goods in presented invoice:100 tables, unit price: USD 100 FOB ShenZhen10 tables first shipmenttotal value: USD1000the description of goods in presented invoice is not acceptable.17.the signature of the below bill of lading is complianceL/C requirement: ocean bill of lading18.UCP600 is quite clear in stating that for the purpose of the articles in UCP, branches of a bank in a different country is considered to be sepearate bank. It follows that a branch of a bank in the same country is considered to be the same bank.19. a credit requires the bill of lading to show on board notation which should be dated, stamped and countersigned. In this respect if the bill of lading is signed by the carrier, the notation should not be countersigned by the carrier.20. a credit subject to UCP600 calls for “international consignment not- copy for shipper”. An international consignment note is presented without the words or marking “copy for shipper”, neither does it show for whom the document has been prepared. The document without the words or making “copy for shipper”creates a discrepancy.SELF CHECKING ANSWER LISTPart 1 单项选择1C2C3B4A5A6A7B8A9A10A11B12B13A14AC15B16A17C18B19C20A21C22C23A24C25C26C27A28C29B30BPART 2 多项选择1AB2BCD3C4ACD5ACD6ABD7ACD8AD9ABD10D11C12AC13BD14AD15BC16AB17ABCD18A19BC20ACPART 3 判断是非1W2R3R4W5W6W7R8W9R10R11W12R13R14R15WPART 4 判断正误1F2F3F4F5F6F7T8F9F10F11F12F13T14F15T16F17T18T19F20F。
