Passage 1If you travel by air across the center of Africa or South America, you fly over forests for thousandsof kilometers. These great forests are the oceans of trees. There are thousands and thousands of different kinds of plants and animals.However, the world's forests are getting smaller all the time. We are cutting down the trees because we need wood, and we need more farmland. Some people say that there will not be any forests like these in 20 or 30 years. What will happen if they disappear?If we cut down our forests, a lot of plants and animals will disappear from the world. In a lotof places the new farmland will soon look like the old deserts. Crops will not grow there. It willnot rain very often, and the weather will get very hot. Perhaps the climate of the world will change. This will be dangerous for everyone in the world. That is why we must take care of our forests.1、The passage mainly tells us about the importance of taking care of plants.所选答案： A.

T问题16 得 2 分，满分 2 分Passage 2Paper is one of the most important products ever invented by man. Wide spread use of written language would not have been possible without some cheap and practical material to write on. The invention of paper meant that more people could be educated because more books could be printed and distributed. Together with the printing press, paper provided an extremely importantway to communicate knowledge.How much paper do you use every year? Probably you cannot answer that question quickly. In 1900 the world's use of paper was about one kilogram for each person a year. Now some countries use as much as 50 kilograms of paper for each person a year. Countries like the United States,England and Sweden use more paper than other countries.Paper, like many other things that we use today, was first made in China. In Egypt and the West, paper was not very commonly used before the year 1400. The Egyptians wrote on a kind of material made of a water plant. Europeans used parchment for many hun-dreds of years. Parchment was very strong; it was made from the skin of certain young ani-mals. We have learnt of the most important facts of European history from records that were kept on parchment. (208 words)6.

What is the main idea of this short talk?所选答案： C.The invention of paper is of great significance to man.问题21 得 2 分，满分 2 分Passage 3What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result of where and how you live? These are very old questions and the answers to them are still not clear.We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle. It needs exercise. Mental exercise is particularly important for young children. Many child psychologists (心理学家) think that parents should play with their children more often and give them problems to think about. The children are then more likely togrow up bright and intelligent. If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent.Parents should also be careful with what they say to young children. According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the childis more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive things to their children, such as "That was a very clever thing you did." or "Y ou are such a smart child."11、The word "intelligent" in the 1st paragraph probably mean bright.所选答案： A.

We will argue over it and mayregardless of whether it is or isn’teven, as a nation, make some fairly solemn- sounding commitments to avoid it. But the moredramatic and meaningful these commitments seem, the less likely they are to be observed.ould put us onA1 Gore calls global warming an “inconvenient truth”, as if merely recognizing it ca path to a solution. But the real truth is that we don’t know enough to relieve global warming, and — without major technological breakthroughs —we can’t do much about it.6.4 billion to 9.1 billion, aFrom 2003 to 2050, the world’s population is predicted to grow from42% increase. If energy use per person and technology remain the same, total energy use andgreenhouse gas emissions (mainly, CO2) will be 42% higher in 2050.But that’s too low, because societies that grow richer use more ene rgy. We need economic growth unless we leave the world’sliving standards. With modest growth,poor to their present poverty and freeze everyone else’senergy use and greenhouse emissions will more than double by 2050.No government will adopt strict restrictions on economic growth and personal freedom (limits onelectricity usage, driving and travel) that might cut back global warming. Still, politicians want toshow they’re “doing something” Consider the Kyoto Protocol. It allowed countries that joined topunish those that didn’t.But it hasn’t reduced CO2 emissions (up about 25% since 1990), and-2012 targets.many signatories didn’t adopt tough enough policies to hit their 2008The practical conclusion is that if global warming is a potential disaster, the only solution is newtechnology. Only an aggressive research and development program might find ways of breakingour dependence on fossil fuels or dealing with it.reallyThe trouble with the global warming debate is that it has become a moral problem when it’an engineering one. The inconvenient truth is that if we don’t solve the engineering problem,we’re helpless.16．What is said about global warming in the first paragraph?所选答案： D.Very little will be done to bring it under control.问题27 得 2 分，满分 2 分17．According to the author’s understanding, what is Al Gore’s view on global warming?所选答案： C.It is a problem that can be solved once it is recognized.问题28 得 2 分，满分 2 分18．Greenhouse emissions will more than double by 2050 because of _______.所选答案： A.economic growth问题29 得0 分，满分 2 分19．The author believes that, since the signing of the Kyoto Protocol, _______.所选答案： D.international cooperation has contributed to solving environmental problems问题30 得0 分，满分 2 分20．What is the message the author intends to convey?所选答案： D.People have to give up certain material comforts to stop global warming.问题31 得 2 分，满分 2 分第三部分:词汇与结构（每小题2分，满分20分）此部分共有5个未完成的句子，针对每个句子中未完成的部分有4个选项，请从 A.B.C.D四个选项中选出正确选项。
