(Student's sample) I have always considered college life is easy and colorful. But the idea disappeared when I go to college. College teachers are normal and they can not well teach us. So I am absent from class, I decide to learn by myself. I work very very hard and I have a dream to be the best student. When I graduate from college, my teacher said to me you are the best student. (Improved sample) I had thought that college life was easy and colorful. But when I went to college, I found I was wrong. College teachers were far from experts as I had expected and some even could not teach us well. So I began to be absent from class and decided to learn by myself instead. I worked very hard in the hope of being the best student. Finally, my dream came true when my teachers told me I was the top student upon my graduation.
Part Ⅱ Reading Comprehension (Skimming and Scanning) Directions:In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1 - 7, mark Y (for YES) if the statement agrees with the information given in the passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. For questions 8 - 10, complete the sentences with the information given in the passage. Before humans came on the scene, the world changed only slowly. The climate warmed and cooled, new plants and animals evolved (进化) and became extinct in their turn, and sea levels rose and fell over periods of thousands, if not millions, of years. But during the last two thousand years there have been very great changes. Forests have disappeared, river courses have been changed, and large areas of natural vegetation have turned into farmland and cities. There are serious problems for the survival of the human race. The Greenhouse Effect It may be cold outside, but on a sunny day it can be hot in a greenhouse. Some of the gases in the Earth's atmosphere act like the glass in a greenhouse. Radiant heat from the Sun can pass through them to warm the Earth below. But the ground also loses heat by radiation (辐射). The "'greenhouse gases" send some of this heat back towards the Earth's surface and help to keep it warm. However, by burning fuels and forests, we are putting larger and larger amounts of these greenhouse gases into the atmosphere. As a result, the Earth is slowly warming up. This is called the greenhouse effect. The greenhouse effect could cause dry weather in some parts of the world. If the polar icecaps melt and sea levels rise, many areas of the world will be flooded. Scientists believe that the only way to slow the greenhouse effect is for us to produce less of the gases which cause it. Air Pollution and Acid Rain Pollution is caused when what we do damages our surroundings. Factories, power stations and motor vehicles send waste gases and soot (烤烟) into the air. The polluted air damages people's lungs. Some petrol had lead in it. The lead comes out in car exhaust fumes and it can cause brain damage in children. The waste gases coming from burning coal, oil and petrol include sulphur (硫黄) dioxide and nitrogen (氮) dioxide. These gases may dissolve (溶解) in water in the atmosphere to form weak acids. They later fall to the Earth as acid rain, sometimes hundreds of kilometers from where they were formed. Much of the acid rain in Canada is caused by smoke from factories and power stations in the USA; the acid rain in Scandinavia may come from Britain. Acid rain attacks trees and other plants, and kills the fish and water animals living in lakes and rivers. Acid rain and polluted air also damage the bricks and stonework of buildings, and corrode (Neck) the metalwork of steel bridges and railings. Acid rain is difficult to control because it spreads so far. And the ways of avoiding acid rain are all expensive. The Ozone Hole Ozone (臭氧) is a gas which forms a layer around the planet at about 20 to 50 km above the Earth's surface. The ozone layer prevents the Sun's dangerous ultraviolet radiation reaching the Earth where it would damage our skin and cause cancers. Many scientists are worried that the ozone layer is being destroyed by the CFCs which are used in refrigerators and freezers. These chemicals are also important greenhouse gases. At certain times of the year the ozone layer becomes extremely thin near the north and south poles. Already skin cancers are increasing in Australia. Many countries are trying to stop the production of CFCs and to find other chemicals to do the same thing. Radioactive Waste Nuclear power stations produce waste which is radioactive. Some of this waste is released by the power stations into the air or water; some is stored. It can be carried long distances by wind or by water. Many scientists worry about the long-term effects of this type of pollution on humans and wildlife.
1. The greenhouse effect is caused by radiant heat from the Sun, which passes through the glasses and thus warms the Earth below.
7. Scientists are having a hot discussion on how to solve the problems of radioactive waste because people will be largely dependent upon nuclear power in the future.
dry weather in some parts of the world and meanwhile floods in many areas of the world if the polar icecaps melt and sea levels rise

Part Ⅳ Reading Comprehension (Reading in Depth)
Section A Directions:In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once. Tourism was one of the fastest growing social and economic phenomena of the last century, and there is no sign of slowdown in the 1 century. The number of tourists will continue to increase, and they will come from wider socio-economic groups and a wider geographic spread than at 2 . 3 leisure time, cheaper travel and rising curiosity about other lands 4 a bright future for the tourism industry. For developing countries, tourism offers the 5 of economic stability and a better future for their citizens. Compared 6 other industries, tourism is thought of as a "smokeless industry". Its positive impacts are self-evident. To begin with, the economic effects of tourism can be 7 into four groups: the effects on income, on employment, on investment, and development. The evidence can be summarized in this way: 8 tourism to an area increases, rapid success and expansion may lead to yet more investment in both tourism and other industries in that area. 9 from its economic effects, tourism is also valuable in personal and social aspects because it satisfies the objectives of direct contact between people. Last but 10 least, the greatest social value of tourism lies in cross-cultural exchange. A. categorized I) not B. promise J) current C. now K) bring D. if L) hope E. more M) present F. at N) sort G. with O) apart H) besides
1.
J
此处需要一个形容词,且按照句意应与the last century“上世纪”相对,因此current为正确答案,the current century意为“本世纪”。present虽然也可以搭配,但下题中会作为名词出现,无法重复使用。
last but not least是固定短语,意为“最后的但非最不重要的”,通常用来引出最后一点。
Section B Directions:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.
Passage One Even though we have more choice of what to eat than forty years ago, the average diet of the average Briton is less healthy. In fact, according to recent research, British pets, eating specially prepared tinned food, have a healthier diet than most of their owners. Health ministers were alarmed at recent figures which show that Britain has the third worst record in Europe for heart disease. Cancer is also a growing cause of illness and death. This has led the government to try to launch a campaign to encourage healthier eating habits. Health ministers believe we should take a lesson from America, where death rates from heart disease have fallen. The American public is now much more aware of the link between diet and good health. The campaign will encourage the eating of less animal fat, salt and sugar than are consumed at present. It will show the advantages of eating more fresh fruit and vegetables. The Health Department is going to issue a booklet which will give guidance on what food to eat and what to avoid. Discussions are being held between the government and food manufacturers. Following these talks, food will be labeled so that consumers can clearly see how much fat, sugar and salt there is in the food products they buy.
1. Which of the following statements is TRUE?
A.British people had less choice of food and an unhealthier diet 40 years ago.
B.British people enjoy a better and healthier diet now than 40 years ago.
C.British people have more choice of food but don't eat as well as they did 40 years ago.
D.Things hardly change as far as what the British people eat is concerned.
A B C D
C
细节题。见文章第一段第一句Even though we have…,the average diet of the average Briton is less healthy(虽然相比40年前可供我们选择的食物多了,但普通英国人的一般饮食却不如以前那么健康了)。因此,C项为正确答案。
2. What made health ministers realize that they must encourage healthier diet?
A.The great number of people suffering from heart disease and cancer.
B.The discussions between the government and food manufacturers.
3. What kind of food does not cause heart disease?
A.Animal fat.
B.Salt.
C.Sugar.
D.Vegetables.
A B C D
D
细节题。见第二段最后两句The campaign will encourage…more fresh fruit and vegetables(活动将会号召大家少吃动物脂肪、盐和糖,并将向大家展示食用更多水果和蔬菜的好处)。由此可确定D项“蔬菜”为健康食品,不会导致心脏病。
4. We can safely draw the following conclusions EXCEPT that ______.
A.the specially prepared tinned food for pets is usually a healthier diet
B.it will be easier for the British to know which foods are bad for their health in the future
C.more Americans died of heart disease in the past than now
D.unhealthy diet is responsible for all diseases
A B C D
D
推断题。根据第一段的British pets,…diet than most of their owners,A项“为宠物准备的特殊罐装食物通常是更健康的饮食”是可推断出的结论。由于文中第四段的food will be labeled…there is in the food products they buy,可得出B项“将来英国人会更容易知道哪些食品对他们的健康有害”这一结论。而第二段的Health ministers believe…from heart disease have fallen. 明确地告之C项“过去更多的美国人死于心脏病”也是正确的推断。只有D项“所有疾病都源自于不健康的饮食”是文中内容从未涉及到的。因此,D项为正确选择。
5. The word "launch" (Line 3, Para. 2) can be best replaced by ______.
A.decide
B.start
C.order
D.send
A B C D
B
词义推断题。原句This has led the government to try to launch a campaign to encourage healthier eating habits应理解为“这就导致了政府设法要发动一场鼓励更健康的饮食习惯的运动”,因此launch a campaign是指“发动或发起运动或 活动”,这里launch意思与start一致。
Passage Two There were times when she was ill and could not leave her bed for months and even years. There were times when she worked day and night, visiting hospitals, making plans for the care of the poor and the sick, talking with important government officers, writing reports. Two great aims were ever before her: improving the conditions of the common soldiers in the army, and making nursing a well-paid, respected life-work for women. In both of these aims she had great success. Because of her, nursing is what it is today. The Nightingale Training School for Nurses was started near one of the large hospitals of England. The fine training that thousands of young women received here during the years that followed has greatly changed nursing all over the world. The little book on nursing which she wrote at this time is still interesting to read. It may contain little which is new to people today, but to the people of her day her ideas were most surprising. Thousands of copies were sent to mills, workshops, villages and schools, and it was translated into three European languages. The simple, direct advice on the care of sick people was much needed and most helpful.
1. Whom is the passage talking about?
A.Helen Keller.
B.Florence Nightingale.
C.Marie Curie.
D.George Washington.
A B C D
B
推断题。本文第一段谈论了一位勤奋工作的女性,她的工作与医务有关,她的目标之一是提高护理工作的薪水和地位。第二段第二句话谈到了Nightingale Training School for Nurses(南丁格尔护士培训学校),由此可知,本文谈论的女性是B项(弗罗伦斯·南丁格尔)。
2. She was successful in ______.
A.improving the pay and status of nursing
B.improving the conditions of the soldiers
C.translating her book on nursing into several languages
D.Both A and B
A B C D
D
细节题。见本文第一段后两句TWO great aims…great success(她面前始终有两大目标:一是改善军队普通士兵的条件;二是使护理成为薪金不薄且受人尊重的一种女性的终生职业。她在这两大目标方面都是成绩斐然),因此D项“提高护理工作的薪水和地位”、“改善士兵的条件”为正确答案。
3. What is the main idea of Paragraph 2?
A.The Nightingale Training School for Nurses.
B.The contribution she made to nursing.
C.The little book she wrote on nursing.
D.Her life.
A B C D
B
主旨题。第二段的第一句Because of her,nursing is what it is today(正是因为她,护理工作才有了今天这样的面貌)为这段的主题句,接下来作者谈到了南丁格尔护士培训学校和她编写的护理学小册子以支持此论点。因此,第二段主要谈论了B项“她对护理学作出的贡献”。
4. It can be inferred in the passage that ______.
A.the advice in the book on the care of sick people was helpful
B.people of her day accepted her ideas in the book well
C.the Nightingale Training School for Nurses played an important role in the changes of nursing all over the world
D.sometimes she was busy visiting hospitals, making plans for the care of the poor and the sick and so on
A B C D
C
推断题。见第二段第三句The fine training…the world,因此可推出C项“南丁格尔护士培训学校在改变全世界的护理学面貌上起到了重要作用”。文中第二和第一段分别明确提到A和D;而根据第二段第五句to the people of her day her ideas were most surprising,B项不符文意。因此C项为正确选择。
5. What is the author's attitude towards Nightingale?
