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.Paragraph l ____【单选题】

A.Life of Macroscopic Bacteria in Livestock\'s Rumen

B.Ways to Reduce Methane\'s Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane

E.Methane as a Strong Greenhouse Gas

F.Livestock as a Prime Factｏｒof the Greenhouse Effect

正确答案:E

答案解析:本段的第3句点出了“methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide. ”

3、Longer Lives Are Happier Lives1 In recent years, scientists have been studying ways to change the body\'s chemistry to reduce the signs ａｎｄ　effects of aging.2 0neｇｒｏｕｐof researchers in Britain has performed experiments on a kind of worm. They have managed to increase the worm\'s normal life span of 20 days by up to 400%. They hope that they will be able to use this research to help humans live longer. However, this is a long way in the future. Another disadvantage is that when (ｏｒif) the new technology is successfully developed, it will probably be very expensive. The chance to live longer will only be available to a very few, very rich people.3 Anotherｇｒｏｕｐof scientists is studying people who have reached a very old age. They believe that this may show what has kept these people healthy ａｎｄ　alive fｏｒso long. So, if we look at people who have lived into very old age, what do they have in common? Usually they have led a physically active life. This does not mean going to a gym ｏｒrunning ten miles every day. Simple, enjoyable activities like walking seem to be more likely to keep you healthy. Very old people also eat a good, varied diet. Simple foods like vegetable, rice, pasta ａｎｄ　fish are the best.4 However, there may be one thing even more important than physical factors like diet ａｎｄ　exercise. Research shows that personality, ａｎｄ　the way a person thinks, play an important part in how long they will live. People who live into very old age always seem to enjoy life. They have a sense of humｏｒａｎｄ　get satisfaction from simple things. They do not constantly think about the past, but are interested in the present ａｎｄ　the future. They do not let life get boring, but have interests ａｎｄ　hobbies which keep their minds active ａｎｄ　they are open to new ideas. One Japanese man who lived to be 120 commented that the secret of his long life was "not worrying". To express it simply, people who are happy ａｎｄ　positive about life are more likely to live longer.5 So, eat well, exercise well, ａｎｄ　enjoy life, ａｎｄ　you will have a good chance of living to a healthy, happy old age.Paragraph 2 ____【单选题】

A.How to live happy old age

B.Disadvantages of the project

C.The study of old people

D.Personality ａｎｄ　other mental factors are more important

E.Worms live longer than humans

F.Live simple lives

正确答案:B

答案解析:由“Another disadvantage is…”可以看出一共说了两个弊端，以此说明想让人们活的长久的这个实验是不可行的。

4、Britain\'s Solo SailorEllen MacArthur started sailing when she was eight, going out on sailing trips with her aunt. She loved it so much that she saved her money fｏｒthree years to buy her first small sailing boat. When she was 18, she sailed alone around Britain ａｎｄ　won the "Young Sailｏｒof the Year" award.Ellen became famous in 2001. Aged only 24, she was one of the only two women who entered the Vendee Globe round the world solo race, which lasts 100 days. Despite of many problems, she came the second in the race out of 24 competitors ａｎｄ　she was given a very warm welcome when she returned.Ambition ａｎｄ　determination have always been a big part of Ellen\'s personality.

It took her many hours to make the repairs, Ellen says: "I was exhausted when came down. It\'s hard to describe how it feels to be up there. It\'s like trying to hold onto a big pole, which fｏｒme is just too big to get my arms around, with someone kicking you all the time ａｎｄ　trying to shake you off".But in her diary, Ellen also describes moments which is worthwhile (值得的) :"A beautiful sunrise started the day, with black clouds slowly lit by the bright yellow sun. I have a very strong feeling of pleasure, being out here on the ocean ａｎｄ　having the chance to live this. I just feel lucky to be here."In the Vendee Globe race, Ellen won ____.【单选题】

5、Travel Across AfricaFｏｒsix hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks ａｎｄ　sａｎｄ　ａｎｄ　baking sun. Knowing our journey was ending, Daniel ａｎｄ　I just wanted to remember all we had seen ａｎｄ　done. He used a camera. I used words. I had already finished three notebooks ａｎｄ　was into the fourth, a beautiful leather notebook I\'d bought in a market in Mozambique.Southern Africa was full of stories ａｎｄ　visions. We were almost drunk on sensations. The roaring (咆哮) of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.ａｎｄ　then the other things, dogs in the streets, whole families in Soweto livng in one room, a kilometre from clean water.As we drove towards the setting sun, a quietness fell over us. The road was empty ａｎｄ　we hadn\'t seen another car fｏｒhours. ａｎｄ　as I drove, something caught my eye. Something moved close enough to touch them, to smell their hot breath. I didn\'t know how long they had been there next to us.I shouted to Dan: "Look!" But he was in a deep sleep, his camera lying useless by his feet. They raced the car fｏｒa few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened."Wild horses?" he said. "Why didn\'t you wake me up, Sophia?""I tried, but they were gone after a few seconds.""Are you sure you didn\'t dream it?""You were the one who was sleeping!""Typical," he said, "The best photos are the ones we never take."We checked into a dusty hotel ａｎｄ　slept the sleep of the dead.While driving Daniel ａｎｄ　Sophia saw wild horses.【单选题】
