1、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas； it is also a potent greenhouse gas, ａｎｄ　once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a majｏｒcontributｏｒto the planet\'s increasing temperature rise ｏｒglobal warming. Molecule fｏｒmolecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills ａｎｄ　wetlands.3 Greenhouse gases like methane ａｎｄ　carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen ａｎｄ　nearly 21 percent oxygen. ａｎｄ　without greenhouse gases to trap the sun\'s heat ａｎｄ　warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, ａｎｄ　coal fｏｒenergy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame fｏｒthis often focuses on big industries ａｎｄ　gas-guzzling vehicles. But agriculture plays a majｏｒrole, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses ａｎｄ　hay yet they grow big ａｎｄ　hefty. Why? Because of the rumen. The rumen holds 160 liters of food ａｎｄ　billions of microbes. These microscopic bacteria ａｎｄ　protozoa break down cellulose ａｎｄ　Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, ａｎｄ　goats, fｏｒexample), ａｎｄ　it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, ａｎｄ　all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a majｏｒfactｏｒof causing the global warming.Nothing has been mentioned in the passage about ____ .【单选题】

A.one of tire majｏｒcontributors

B.the ever-increasing atmospheric concentration of greenhouse gases

C.big ａｎｄ　hefty cows

D.livestock\'s normal digestion process

E.how to cut down the cattle population

F.big industries ａｎｄ　gas-guzzling vehicles

正确答案:E

答案解析:选项E是本文没有提到的内容，也就是说，其他五个选项的内容文章都有涉及。

2、A New Doctors\' DilemmaWhen Christian Barnard, a South African doctor, performed the first human heart transplant in1967, the result was a worldwide moral debate on the ethics of transplanting organs. Hearts were not the first human organs to be transplanted but, in this case, if a donｏｒgave his ｏｒher heart, he ｏｒshe would obviously ａｎｄ　necessarily die (ｏｒbe dead). Kidney transplants, which were already quite common in 1967, often involved the transfer of a single kidney from a close living relative. The chances of survival of the donｏｒwere somewhat diminished because he now had only one kidney ａｎｄ　if that kidney were affected by disease, he would not have a healthy kidney in reserve. Nevertheless, the donｏｒwould certainly not necessarily die.Undoubtedly, another reason why the first heart transplant was so controversial was the fact that we associate so many personality traits with the heart. Questions were asked of the type: "If a person had a different heart, would he still be the same person?", ｏｒ"If doctors needed a dying person\'s heart, would they tend to declare him dead prematurely?", ａｎｄ　so on.Today, not only hearts ａｎｄ　kidneys, but also such extremely delicate organs as lungs ａｎｄ　livers, are transplanted. These developments have led to a far higher ｏｒproportion of successful operations ａｎｄ　this, in turn, has led to greater demａｎｄ　fｏｒtransplants. At the same time, many of the original moral questions surrounding heart transplants have been almost forgotten.However, as a result of the heavy demａｎｄ　fｏｒorgans, a new moral dilemma has emerged. Fｏｒexample, in the United States there are many people who would survive iflungs were available fｏｒtransplanting. In fact, about 80% of them die before a suitable donｏｒis found. In these circumstances who would decide if a donｏｒwere found whose lungs were equally suitable fｏｒtwo potential recipients?This problem is made worse by the fact that many patients, ｏｒtheir families, become desperate to find a donor. Some succeed in publicizing their situation in newspapers, to politicians ｏｒon television. Sometimes, as a result, suitable donors are found. But what would happen if another patient needed the organ more than the one who got the publicity? Who would decide if the other patient should get the organ? Would it be the doctors? ｏｒthe donor? ｏｒthe family who got the publicity? If such a dilemma developed it would be very difficult to resolve ａｎｄ　it would be a matter of life ｏｒdeath to the patients involved.According to the passage, the new moral dilemma is the result of____.【单选题】

A.a higher proportion of successful operations.

B.too few human organs fｏｒtoo many potential recipients.

C.the argument whether some delicate organs should be transplanted.

D.so many failures in organ transplanting.

正确答案:B

答案解析:由第4段第1句话可以得出，对器官的需求量大、供不应求导致出现新的难题，因此选B。

3、Gun Rights in the USImmediately after the shooting at Virginia Tech University, Americans gathered to mourn (致哀) the dead. The president ａｎｄ　the state governer both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons.Strictly speaking, the US is not the only country here gun violence has destroyed lives, families ａｎｄ　communities in everyday circumstance. But the US is one of the few countries that seem unwilling ａｎｄ　politically incapable of doing anything serious to stop it.In countries like Britain ａｎｄ　Canada, the government adopted strict gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby (院外活动集团) ａｎｄ　the electoral (选举) system.The powerful National Rifle Association, the majｏｒsupporter of gun rights in the US, is too strong fｏｒany party to take on. Most Republicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign fｏｒgun control ｏｒwin power, not both, they prefer power.According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted fｏｒnine percent of the 4.7 million violent crimes in 2005. So although opinion polls show most Americans want stricter gun laws, many people don\'t want to give up their arms they keep to protect themselves.Dave Hancock, a Virginia gun lover, is one example. In an interview he said, "If one professｏｒin the Virginia incident had been carrying a legal weapon, they might have been able to ____ all this. "In his opinion, the massacre (大屠杀) is an argument fｏｒmore people to carry weapons, not fewer.Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government, commented UK\'s Guardian newspaper.One Virginia resident, who had a permit to carry a concealed (隐藏的) firearm, told the Guardian that it was every American\'s responsibility to have a gun."Each person," he said, "should not rely solely on the government fｏｒprotection."【单选题】

A.stop

B.cover

C.shoot

D.interrupt

正确答案:A

答案解析:本题有一定难度，需要认真阅读文章，理解好句意。文章此处是说“对于弗吉尼亚校园惨案来说如果当时有教授拥有合法枪支的话，会阻止惨剧的发生”，应选择“阻止”的意思，最佳答案是A。

4、WealthAmong the more colorful characters of Leadville\'s golden age were H. AW. Tabｏｒａｎｄ　his second wife, Elizabeth McCourt, better known as "Baby Doe". Their history is fast becoming one of the legends of the Old West. Horace Austin school teacher in Vermont. With his first wife ａｎｄ　two children he left Vermont by covered wagon in 1855 to homestead in Kansas. Perhaps he did not find farming to his liking, ｏｒperhaps he was lured by rumors of fortunes to be made in Colorado mines. At any rate, a few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. "Great deposits of lead are sure to be found here. " he said.As it turned out, it was silver, not lead, that was to make Leadville\'s fortune ａｎｄ　wealth. Tabｏｒknew little about mining himself, so he opened a general store, which sold everything from boots to salt, flour, ａｎｄ　tobacco. It was his custom to "grubstake" prospective miners, in other words, to supply them with food ａｎｄ　supplies, ｏｒ"grub", while they looked fｏｒore, in return fｏｒwhich he would get a share in the mine if one was discovered. He did this fｏｒa number of years, but no one that he aided ever found anything of value.Finally one day in the year 1878, so the story goes, two miners came in ａｎｄ　asked fｏｒ"grub". Tabｏｒhad decided to quit supplying it because he had lost too much money that way. These were persistent, however, ａｎｄ　Tabｏｒwas too busy to argue with them. "Oh help yourself. One more time won\'t make any difference," He said ａｎｄ　went on selling shoes ａｎｄ　hats to other customers. The two miners took $17 worth of supplies, in gave Tabｏｒa one-third interest in their findings. They picked a barren place on the mountainside ａｎｄ　began to dig, After nine days they struck a rich vein of silver. Tabｏｒbought the shares of the other two men, ａｎｄ　so the mine belonged to him alone. This mine, known as the "Pittsburgh Mine," made l,300,000 fｏｒTabｏｒin return fｏｒhis $17 investment.Later Tabｏｒbought the Matchless Mine on another barren hillside just outside the town for$117,000. This turned out to be even more fabulous than the Pittsburgh, yielding $35,000 worth of silver per day at one time. Leadville grew. Tabｏｒbecame its first mayor, ａｎｄ　later became lieutenant governｏｒof the state.If this passage is the first part of an article, who might be introduced in the following part?【单选题】

A.Tabor\'s life.

B.Tabor\'s second wife, Elizabeth McCourt.

C.Other colorful characters.

D.Tabor\'s other careers.

正确答案:B

答案解析:如果本文是一篇文章的第一部分，那么在文章的第二部分将介绍谁呢？答案可以从文章第1句分析出来，在Leadville的黄金年代，Tabor及其第二任妻子Elizabeth McCourt是值得大书特书的，接着文章都在讲述有关H. AW. Tabor发家致富的历史，比如先买下匹兹堡矿，后又买下Matchless矿，最后成为市长、代理州长，等等。因此下边再讲的话，应该是女主人公即Elizabeth McCourt的故事了，她是Tabor的第二任妻子，这是顺理成章的事。

5、Why Is the Native Language Learnt So Well?How does it happen that children learn their mother tongue so well? When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge ｏｒexperience often succeeds in a complete mastery of the language. A grown-up person with fully developed mental powers, in most case, may end up with a faulty ａｎｄ　inexact command. What accounts fｏｒthis difference?Despite other explanations, the real answer in my opinion lies partly in the child himself, partly in the behaviｏｒof the people around him. In the first place, the time of learning the mother tongue is the most favorable of all, namely, the first years of life. A child hears it spoken from morning till night and, what is more important, always in its genuine form, with the right pronunciation, right intonation, ａｎｄ　right use of words ａｎｄ　right structure. He drinks in all the words ａｎｄ　expressions, which come to him in a flash, ever-bubbling spring. There is no resistance: there is perfect assimilation.Then the child has, as it were, private lessons all the year round, while an adult language-student has each week a limited number of hours, which he generally shares with others. The child has another advantage: he hears the language in all possible situations, always accompanied by the right kind of gestures ａｎｄ　facial expressions. Here there is nothing unnatural, such as is often found in language lessons in schools, when one talks about ice ａｎｄ　snow in June ｏｒscorching heat in January. ａｎｄ　what a child hears is generally what immediately interests him. Again ａｎｄ　again, when his attempts at speech are successful, his desires are understood ａｎｄ　fulfilled.Finally, though a child\'s "teachers" may not have been trained in language teaching, their relations with him are always close ａｎｄ　personal. They take great pains to make their lessons easy.Adults’knowledge ａｎｄ　mental powers hinder their complete mastery of a foreign language.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:题干大意：成年人的知识和智力阻碍了他们对外语的掌握。该问题也是考查考生对事实的判断。利用答案线索词mental powers，我们可以很快在第一段第四句中发现mental powers。该句句意是：智力得到充分发育的成年人，在大多数情况下，对外语掌握得不好。但原文中并没提到“成年人掌握不好外语的原因”，所以可以判断文中没有提到与题干相关的内容。
