2、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."Which statement about Barth is NOT true? ____【单选题】

A.He is 33 years old now.

B.He works at a Goodwill thrift shop.

C.He works at a Salvation Army thrift shop.

D.He was a college student many years ago.

3、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 _____ 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 impossible 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.opened

B.occurred

C.opposed\'

D.operated

正确答案:B

答案解析:本段叙述地球上记录到的最低温度是-91℃，本段最后一句的后半句显然是交代这一最低温度是在南极洲出现的，所以occurred（发生、出现）是正确的选择。其他三个选项的词义与上下文的意思相去甚远。

4、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 2 ____【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:F

答案解析:本段要表达的中心意思是：livestock排出的甲烷也是温室效应的一个主要源头。

5、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.Why was the first heart transplant controversial?【单选题】

A.Because it was not so successful as people had thought.

B.Because some people argued it was not moral to do so.

C.Because the recipient died on the operation table.

D.Because it was the most difficult operation ever known.

正确答案:B

答案解析:由第1段可知，全球范围的moral debate是因为捐者一定会死的。这不同于肾脏移植，因此违背道德。
