·范文·
    Recently the phenomenon, waste on campus has become a more and more serious problem which has become a heated topic. We can easily see many students dump a lot of food into the garbage can. Some students spend a lot of money buying fashionable clothes, shoes and so on.
    The negative effects of waste can be shown in the following aspects. Firstly, it makes some students dependent on their parents for money, which is harmful to their development. If they don't learn to support themselves, they will be "useless people" when they graduate. Secondly, it is not easy for our parents to arrange for our schooling. Last but not the least important, there is no denying the fact that our country is still poor. There are many people who cannot go to university and many poor people still need our help.
      My opinion is that I should set a good example to reduce waste on campus. First of all, I will refrain from wasting anything, from food to stationery. What's more, I'm determined to call on more schoolmates to fight against waste. Only through these measures can we hope to reduce waste on campus.
Part Ⅱ  Reading Comprehension(Skimming and Scanning)
·文章大意·    人类是不是唯一掌握语言的动物?如何来给"语言"下定义，必将影响到这个问题的答案。科学家们对不同的生物进行了实验，结果发现有些生物确实能够"交换信息"，但它们却做不到"组合符号以交换信息"。这一问题很复杂，目前仍没有定论。
1. Y 见文中第三段第3句 "The tail-wagging dance is used when the food is more than ten meters away"。
2. NG文中第八段讲述了对Lana进行的实验，只说了实验地点，但文章并没有提及实验者的名字。
3. N文中第五段和第六段中都提到海豚具有交换信息的能力，只不过与人相比非常有限而已。"For communication，however，the dolphin's system is much more limited than a person's. The dolphin has three kinds of calls or noises to tell other dolphins about food, danger, or other things. " (Para. 5) 和 "It seems that bees and dolphins communicate, …"(Para. 6)。
4. N文中第一段和第九段都提到要想回答动物是否具有语言，必须要看语言是如何来定义的。"It is a very difficult question to answer．A person must have a good definition of 'language'." (Para. 1)和"of course，the answer to this question depends on how 'language' is defined." (Para. 9)。另外，在第九段结尾又指明"This is not their usual language, however." 这毕竟不是它们常用的语言。
5. distinguish根据本文第五段中"The dolphin has three kinds of calls or noises to tell other dolphins about food, danger, or other things", 由此可知海豚可以区分这三种不同的叫声。
6. much similar to/much like 见本文第五段中"The dolphin has been studied because its general behavior is much like that of humans."。
7. mouth and throat根据本文第六段"Part of the problem with this experiment is that monkeys do not have the same kind of mouth and throat as humans. They are not really able to make human speech sounds.", 由此可知猴子不具备与人相同的发音器官。
8. make sentences见本文第八段中"The scientists who are working with Lana are studying her ability to make sentences."。
9. unusual文中第九段最后一句"This is not their usual language, however.", 指明这毕竟不是猴子常用的语言。
10. exchange information文中第九段中提到语言的两种定义: "any system for exchanging information"和"a system for exchanging information by making new combinations of symbols"；在第十段中又指出动物语言是一个复杂的事物，还需要进一步实验才有可能说得清楚。

     The Golden Gate Bridge joins the beautiful city of San Francisco with the suburbs to the north. Each day about one hundred thousand automobiles cross the bridge taking people to and from the city. More than haft of them cross the bridge during the morning and evening rush hours when traffic is so heavy the trip is not pleasant. Now however there is at least one group of happy commuters. These are the people who travel under the bridge instead of on it. They go to work by boat and enjoy it so much that most of them say they will never go by car again. The ferry, they take is spacious, quiet and comfortable. Commutes, can enjoy the sun on deck. In the morning they can have breakfast in the coffee shop. And in the evening they can order a drink in the bar while looking at the beautiful scenery. The trip takes only 30 minutes and is not very costly. Best of all, being on a boat seems to make people more friendly toward each other.  There has already been a marriage of two commuters who met on the ferry. Because the ferry has been so successful, there are plans to use other still larger boats. There is also a proposal for a high speed boat that will make the trip in only 15 minutes. But not everyone is happy about that. A lot of people feel that half an hour is just enough time to relax.

Passage Two
How many teeth have you had filled in the past two years? If you follow the advice of Dr. Faustick you may be able to reduce the number of your visits to a dentist. Dr. Faustick conducted a two-year survey to find out how to prevent or reduce dental decay. 946 students took part in an experiment. 523 students cleaned their teeth within ten minutes of eating when possible they used a toothbrush, when this was impossible they washed their mouth thoroughly with water. The remaining 423 students merely cleaned their teeth when they went to bed and when they got up in the morning. All the students had their teeth X-rayed at the end of the first and second years. At the end of the first year, the night and morning group had three times as many decayed teeth as the clean after each meal group. At the end of the second year the latter group had 53 percent fewer decayed teeth than the former group. Dr. Faustick has cleaned his teeth after every meal for thirteen years and has not had a single decayed tooth. He pointed out that sugar is a major agent in dental decay. Particularly the sugar in sweets, cakes, and soft drinks. Ideally you should keep a tooth brush in your pocket and use it immediately after you have finished eating. When this is impractical you can at least make sure that you have a drink of water and let the water through your teeth to force out any particles of food. 7 out of 10 people loose at least half of their teeth by the time they are fifty. Many have a complete set of false teeth by that time. In any case neither toothache nor a visit to a dentist is very pleasant. So it is worthwhile making an effort to keep your own teeth as long as possible. The main preventative agent is simply water.
29. Q: According to the passage what kind of food is most likely to cause dental decay? A)Coca Cola．
细节推理题。Dr. Faustick指出，糖是导致龋齿的主要因素，尤其是糖果，蛋糕和软饮料中的糖
分，选项A是软饮料的一种。
30. Q: What does the passage tell us about the condition of Dr. Faustick's teeth? B) He doesn't have  a single decayed tooth. 推理判断题。文中提到Dr. Faustick 13年来坚持饭后刷牙．所以至今没有一颗龋齿．
31. Q: What does Dr. Faustick suggest to prevent dental decay?
   D) Clean your teeth shortly after eating.
细节判断题。Dr. Faustick的调查结果表明，早晚 刷牙的人龋齿的数量是每顿饭后刷牙的人的3
倍，所以预防龋齿的办法就是饭后清洁牙齿。
Passage Three
    The worldwide organization of the Red Cross stems from the idea of Henri Dunant, a Swiss Banker. In 1838 at the age of ten, Dunant was taken by his father to visit a prison, there he saw  prisoners chained together exercising in the yard and breaking stones along the road. This experience left a deep impression on him.And made him determined to do something for convicts and slaves and for all who were oppressed and deprived of their liberty. On 24th June 1859 while on his way from Geneva to France, Dunant witnessed the battle between the French and Austrian armies. It was one of the fiercest battles of the 19th century. Shocked by the lack of medical supplies and attention given to the wounded, Dunant decided that volunteer service had to be organized. He gathered together a number of women who attended the hundreds of wounded soldiers of all nationalities and helped the surgeons as best they could. From that battle' Dunant determined to form a body of people who would rally together in times of war and attend to the needs of wounded and dying. Dunant held that a suffering human being should be helped for his own sake only, without regard to race, religion, or political beliefs. Many Europeans states supported him and on 22nd August 1864 the first Geneva Convention was signed. This lays down that once a soldier is wounded he and everyone else who comes to his help ceases to be an enemy. A symbol by which the relief workers could be recognized was devised. As a tribute to Switzerland, the symbol was the Swiss flag reversed. That is a red cross on a white ground. So the Red Cross was born.
32. Q: What first led Henri Dunant to think of helping the oppressed? A)A visit to a prison. 细节辨识题。文章开始说到，Dunant 10岁的时候，父亲带他去监狱的经历使他决心为囚犯、奴隶以及所有受压迫和被剥夺自由的人做些事情。
33. Q: What did Henri Dunam do during the battle between the French and Austrian armies? C) He recruited volunteers to care for the wounded. 细节辨识题。法国和奥地利战争期间，Dunant看到伤员得不到医疗救助，决定组织志愿服务，召集志愿者照顾伤员。
34. Q: What was Henri Dunant's belief when he found the Red Cross? D)A suffering person is entitled    to help regardless of race, religion or political beliefs.细节辨识题。Dunant认为，救助伤员应该为伤员本身着想，不应考虑他的种族、宗教或政治信仰。
35. Q: Why was the symbol of the Red Cross designed with a red cross on a white ground? C)To pay tribute to Switzerland. 细节辨识题。文章最后提到，为了表达对瑞士的感激与尊敬，将瑞士国旗反过来作为红十字组织的标志，即白底红色十字标志。

Section C
    President Clinton later today joins (36)former presidents Ford, Carter and Bush at " the president's summit for America's future" (37) aimed at recruiting one million volunteer tutors to provide after-school weekend and summer reading help for up to three million children. Mr. Clinton will ask Congress this coming week for nearly three (38)billion dollars to fund a five-year program called "America Reads".
     The program would fund the (39)coordination efforts of 20 thousand reading (40)specialists and would also give (41)grants to help parents help children read by the third grade, or about age eight. During his Saturday radio (42)address, the president explained why the (43)program is important. "We need  'America Reads' and we need it now. Studies show that if the fourth-graders fail to read well, (44) they are likely to drop out of school, and less likely to succeed in life. But, 40 percent of them still can't read at a basic level. "
     Volunteer tutors, who provide community service in exchange for college funding, are being used in literacy and tutoring programs. (45)The programs, initiated by President Clinton have been criticized by some members of Congress.
     The president says many of the Philadelphia summit's corporate sponsors will recruit tutors. (46) Dozen of colleges and Universities are preparing to send thousands of their students in support of the Program.
Part IV  Reading Comprehension( Reading in Depth)
Section A
文章大意·    本文从一次团队水上旅行说起，阐述了团队合作的重要性，并以此引申开来，提出了团队合作是实现任何梦想的必要条件。
47. They were accustomed to being spoiled and indulged 见文章第一段最后一句，本句句意为在河上仅仅两天之后，这些习惯于被迁就的人们就形成了一支队伍，一起来对付那些河流中突现的漩涡和转弯。可见作者对他们漩涡和转弯。可见作者对他们的描述是"accustomed to being spoiled and indulged of the river".
48. Because of the twists and turns of the river. 从文章第一段可以知道，遇到湍流的时候，我们已经无法顾及面子，只有尽力才能使小船免受倾覆之灾。在第一段最后一句也提到，大家要一起对付河流中突现的漩涡和转弯。
49. It was in adversity 从文章第二段最后一句；可知,这支球队到了90年代才被从逆境中扭转过来,成为一个重要的竞争者。可见，80年代时,球队还处在困境中。
50. The lack of teamwork 文章第四段和第五段对比说明了使用团队合作策略前后的通用公司出现的两种-截然不同的状态由此可以推导出由于缺乏团队合作而导致了矛盾。
51. Teamwork 文章第五段第1句 "…based on teamwork", 基于团队合作,可见是-种团队合作精神。
Section B
Passage one
·文章大意· 本文探讨了妇女外出工作对婚姻和家庭的影响。第一段引出两种不同的观点：一些未来学家提出一种假设，职业女性的剧增可能预示着妇女对婚姻说不；另一种观点则认为一个家庭中两个人赚钱的前景会促使结婚人数增加。接下来，作者具体分析了女性工作对婚姻的正、负面影响。
52. The word " portend" is closest in meaning to  "___________" B) signal 词义推理题。解答此类题目时应抓住上下文，分析其逻辑关系：portend在文章第l句，是主题句，说明职业女性和婚姻的关系；文章第2句是支撑句，意思说根据这个假设，许多妇女将宁愿工作而不愿结婚，据此可推测职业女性数量的增加与拒绝婚姻是因果关系，所以选B项 signal (显示、预示)。
53. It is said in the passage that when the economy slides, _______________D) more people would prefer to remain single for the time being 细节理解题。本题可定位到第一段的倒数第二句中的economic downturns(经济滑坡)，该句句意为：有数据表明，经济下滑会使婚姻延期，因为双方没有经济能力建立一个家庭或者双方担心未来经济拮据的日子。D项中remain single for the time being(暂时保持单身)就相当于原文中的postpone marriage(推迟结婚)。故D项正确。
54. If women find fulfillment through work outside the home, ______________  C) their marriage ties can be strengthened 细节判断题。根据题干可定位到文章第三段的最后一句：如果她能够通过在外工作获得满足感，那么工作和婚姻会一起创造一个更强大、更稳定的联盟。C 项符合文意，且原文中的形容词stronger转化为C项中的动词strengthen，属同义转述。
55. One reason why women with no career may seek a divorce is that ____________. A) they feel that they have been robbed of their freedom 细节理解题。根据题干关键词with no career, seek a divorce可定位到第三段的第2句中blocked from a career(不外出工作)和第3句，可知家庭妇女离婚原因之一就是她们觉得像被关在笼子里一样，这是一种形象的说法，考生应注意理解。因此选A项，feel
caged=feel that they have been robbed of their freedom
56. Which of the following statements can best summarize the author's view in the passage? D) The impact of the growing female workforce on marriage varies from case to case. 综合分析题。作者在最后一句表达了自己的观点：夫妻双方如何应对这种新形势将决定夫妻关系是更稳定还是会出现新的不安定因素。D项(职业女性的增加对婚姻的影响是不尽相同的)与作者的态度相吻合。
Passage Two
·文章大意·    本文针对"人类天性"这个问题进行了探讨。大部分思想家认为是人性构成了
人类的本质，尽管对什么构成了人性有不同的观点，但是大家一致认为人性是存在的，由此人才是人，才是一个合理的存在，是社会动物。但近来这种传统观点已经开始受到质疑。而作者认为从进化的角度可以对人性这个问题有新的理解。
57. The traditional view of " human nature" was strongly challenged by _________________. C) new insight into human behavior 综合归纳题。根据题干的challenge可定位到第二段第l句中questioned。由该段可知，传统的关于人性的观点遭到质疑的理由有两点：一是因为越来越强调从历史的角度来看待人；二是由于人性这个概念经常被人滥用，为一些野蛮的、非人道的行为做辩护。综上所述，提出质疑是从非传统的角度来理解人的行为，是对人类行为的新的理解，即c项。
58. According to the passage, anthropologists believe that human beings _______________. C) are born without a fixed nature 细节判断题。根据题干中anthropologist可以定位到第二段中"many anthropologists arrived at the concept that man is born as a blank sheet of paper on which each culture writes its text．"C项符合文意。
59. The author mentioned Aristotle, a great ancient thinker, in order to _________________. B) show that the concept of "human nature" was used to justify social evils 归纳判断题。典型的例证考题。请考生注意：当问到所举例子的目的时，答案一定指向该例子上面的作者观点句，也就是Another factor的内容，因此选B项。
60. The word " untenable" in the last paragraph of the passage most probably means _______. D) indefensible 归纳推理题。从第三段可知，另外一个对人性怀疑的理由可能是因为进化论的影响，一旦人类被看作是在进化的过程中发展的，那么人类具有某种本质性的东西的观点看起来就站不住脚了。既然作者认为从进化的角度来看，人性应该被质疑，那么可以推断untenable必定是表否定的贬义词，因此D项(不合理的。站不住脚的)正确。
61. Most philosophers believed that human nature _______________. A) is the quality distinguishing man from other animals细节归纳题。题目指向首句及其后内容，大意为大部分哲学家一致同意人类具有天性，因而人才成其为人，成为社会动物。言下之意，才和其它动物有所区
别。因此选A项。
Part V  Error Correction
·参考译文·Thomas Malthus在差不多200年前发表了他的《人口原理评论》。自从那时起，预测者们一直在警告说世界范围的饥荒就在眼前。他们认为，快速增长的人口对食品的需求将很快超过供应，导致广泛的食品短缺和饥饿。
    但实际上，世界总的谷物产量在过去许多年中一直在稳步上升。除了某些相对孤立的动荡地区，比如当今的索马里，还有偶尔某些年份的歉收，世界食品危机还只是继续在附近徘徊。大部分专家认为，这样的情形会继续下去，即使到二十一世纪中叶世界人口翻一番，尽管因为政治、经济和环境因素，养活100亿人不会容易。乐观者提出了一些产量持续增长的具体例子。在非洲，比如说，改善了的种子，更多的化肥和先进的种植技术已经在一次实验里使玉米和小麦产量翻了不止一番。在其它地区，菲律宾的水稻专家正在培育一种植株，拥有更少的茎和更多的种子。虽然无法保证植物培育人员能够继续开发出新的、产量更高的作物，但是大部分研究人员根据他们目前所取得的成功认为(人们)有理由(对此)抱有希望。
62. being→ been时态用法错误。现在完成进行时的标准形式是have been doing。
63. their→its物主代词用法错误。这里代词指代不可数名词food，应该用其单数形式its。
64. relative→relatively修饰形容词的副词用法错误。修饰形容词isolated，应该用副词relatively。
65. good→bad上下文语意理解错误。"偶尔有些年份歉收"，因此改为它的反义词。
66. as 删掉固定搭配用法错误。没有even as if的用法，根据文意，应该用even if(即使)，故去掉as。
67. politics→political形容词误用成名词。平行结构中并列的词，词性应一致。从该句来看，应都使用形容词。
68. by→for固定搭配用法错误。for instance意为"例如"。
69. double→ doubled谓语动词时态用法错误。现在完成时have后面应该接过去分词doubled。
70. few→fewer平行结构用法错误。连接词and前后都应该用比较级。
71. crop→ crops名词单复数错误。crop为可数名词，这里应该用其复数形式crops。
Part VI  Translation
72. The 1980s had seen 这个短语的翻译要注意两点：一是时间的翻译，"二十世纪八十年代"是"the 1980s"；其二，"见证"用"see"表示，为固定句型。另外，时态也需用完成时态。
73. Who feels like hearing the story again 关键在于"想"的翻译，不可使用"want to"，须用词组"feel like doing sth."表示。
74. If you happened to pass a baker "碰巧"的表示法有两种："it happened
that…"和"sb. happened to do sth."，在此处很显然用后者。
75. unless the price dropped to below 2000 yuan 这里考查的是双介词的使用方法，"降到两千元以下"的表示方法为"drop to below 2000 yuan"，两个介词缺一不可。
76. if not all of them "即便不是…"可用固定句型"if not…" 来表示。
