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. ”

2、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.Sophia wrote about her experiences in notebooks.【单选题】

3、African wild dogFinding a babysitter while you go out to work is, fｏｒexample, an inconvenience. Fｏｒthe African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life ａｎｄ　death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food ａｎｄ　stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution ａｎｄ　unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, ａｎｄ　the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults ａｎｄ　pups, only the dominant male ａｎｄ　female breed. The remaining animals help raise the pups, cooperating to hunt prey ａｎｄ　defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions ａｎｄ　hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey ａｎｄ　to defend the kill. There is also one less stomach in which to carry food back to the den, ａｎｄ　one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups ａｎｄ　still spare a babysitter. But with smaller packs, either the hunting ｏｒthe babysitting suffers, ｏｒthe animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals ｏｒfewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poｏｒreproduction ａｎｄ　low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " ａｎｄ　deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.The remaining lions will die out within decades.【单选题】

A.Right

C.Not mentioned

正确答案:C

答案解析:文章第5段提到了“狮子”，但没有说狮子也是濒于灭绝的一种大型食肉动物，尽管事实确是如此。

4、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly _____ to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

A.reasonable

B.wonderful

C.impossible

D.necessary

正确答案:C

5、Shopping at Second - hａｎｄ　Clothing StoresWhen 33 years old Pete Barth was in college, shopping at second - hａｎｄ　clothing stores was just something he did－"like changing the tires on his car." He looked at his budget ａｎｄ　decided he could save a lot of money by shopping fｏｒclothes at thrift shops."Even new clothes are fairly disposable (用后即丢掉的) ａｎｄ　wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons fｏｒshopping fｏｒsecond - hａｎｄ　clothing. Some people, like him, shop to save money. Some shop fｏｒa crazy - looking shirt. ａｎｄ　some shop as a means of conserving energy ａｎｄ　helping the environment.Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, fｏｒher, shopping at thrift shops is a way to help the environment."When my daughter was little, we looked at it as recycling," Akins said: "Also, why pay 30 dollars fｏｒa new coat when you can get another one fｏｒa lot less?"Akins said that the SA has shops all over the US－"some as big as department stores". All of the clothes are donated (捐赠), ａｎｄ　when they have a surplus (盈余), they\'ll have "stuff a bag" specials, where customers can fill a grocery sack with clothes fｏｒonly 5 ｏｒ10 dollars.Julia Stocum, 22, points out, however, that the huge amount of second - hａｎｄ　clothing in the US is the result of American wastefulness."I\'d say that second - hａｎｄ　stores are the result of our wasteful, materialistic culture," said Slocum, who works fｏｒa pro - conservation organization, the center of a New American Dream. "Thrift shops prevent waste from going to landfills (垃圾填埋场), They give clothing a second life ａｎｄ　provide cheaper clothing fｏｒthose who can\'t afford to buy new ones ａｎｄ　generate (创造) income fｏｒcharities. They also provide a way fｏｒthe wealthy ａｎｄ　middle classes to shed (摆脱) the guilt fｏｒtheir level of consumption."When Barth was a college student, he often shopped at thrift shops ____【单选题】

A.to save money.

B.to save energy,

C.to help the environment.

D.to make friends with poｏｒpeople.

7、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。

9、RobotsThe most sophisticated (先进的) Japanese robots, which have vision systems ａｎｄ　work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America ｏｒEurope.Although industrial robots were originally developed as devices fｏｒsimply handling objects, today their commonest uses are fｏｒmore skilled work like welding (焊接), spray-painting ａｎｄ　assembling components.In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive ａｎｄ　partly because engineers now have more experience with robots ａｎｄ　are more aware of the difficulties of introducing them effectively.It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan. The reliability of robots is measured in their MTBF ｏｒmean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day fｏｒtwo years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately ａｎｄ　consistently than humans, who can get tired ａｎｄ　bored.Even the most sophisticated Japanese robots are________.【单选题】

A.too much energy

B.based on American designs

C.they are too costly

D.they are not reliable

E.quality control

F.free of charge

正确答案:B

答案解析:根据题干中的线索词the most sophisticated Japanese robots可定位到第一段第一句话：The most sophisticated（先进的）Japanese robots，which have vision systems ａｎｄ　work at very high speeds, are still based on American designs. B选项“based on American designs”是原句复现。显然B为正确答案。

10、The Race into SpaceAmerican millionaire Dennis Tito will always be famous. He was the first tourist in space. "I spent sixty years on Earth ａｎｄ　eight days in space ａｎｄ　from my viewpoint, it was two separate lives," Tito explained. He loved his time in space. "Being in space ａｎｄ　looking back at earth is one of the most rewarding experiences a human being can have."This kind of experience isn\'t cheap. It cost $ 20 million. However, Tito achieved his dream, so he was happy. "Fｏｒme it was a life dream. It was a dream that began when didn\'t have any money," he told reporters.On 30 April 2002, Mark Shuttleworth became the world\'s second space tourist. Shuttleworth is a South African businessman. At the age of twenty - eight, he also paid $ 20 million fｏｒthe eight - day trip.Both Tito ａｎｄ　Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list fｏｒflights into space. The spaceship to take them doesn\'t exist yet.Many of the customers are people who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because it’s so expensive, only very rich people can go into space. They want space travel to be available to more people.That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an islａｎｄ　in Tonga. The company promises a package that includes forty-five days of astronaut training in Russia ａｎｄ　California, seven days in space, ａｎｄ　a vacation in Tonga, fｏｒ$2 million.However, space flight is still very dangerous. Bill Readdy is NASA\'s deputy assistant administratｏｒfｏｒspace flight. He says that the chances of dying are about 1 in 500. Because of this, it may take time before space tourism really takes off. You might be able to go up, but will you come down?Space Adventures already has a spaceship.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题有一定难度，本题又回到第四段出题，考生需要从第四段寻找答案依据。带着题干提示词Space Adventures迅速回到文章定位。第四段最后一句谈到，运载他们的太空飞船还不存在，所以本题错误，答案是B
