1、Seeing Red Means Danger AheadThe colｏｒred often means danger ａｎｄ　by paying attention, accidents can be prevented. In the future, the colｏｒred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports ｏｒother kinds of materials could one day contain a colｏｒswitching material. It will turn red before a structure collapses ｏｒfalls apart. The secret behind the colｏｒswitching material is a particular type of molecule. A molecule is aｇｒｏｕｐof atoms held together by chemical bonds. Molecules come ______ all shapes ａｎｄ　sizes, ａｎｄ　make up everything. You can see, touch ｏｒfeel. How a molecule behaves depends on what kinds of atoms it contains, ａｎｄ　how they\'re held together. When a polymer (聚合物) containing a colｏｒswitching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" ｏｒweak, one of the mechanophore bonds breaks ａｎｄ　the material turns red. "It\'s a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos ａｎｄ　her team tested the colｏｒswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colｏｒlight when a bright light is shone on the mechanophore. The broken bond is fixed ａｎｄ　the red colｏｒdisappears. This "self-healing" may be a problem fｏｒengineers. They need to use the colｏｒchanger in big construction projects that will be outside in sunlight. ａｎｄ　sunlight will make the mechanophore\'s warming system useless. Sottos ａｎｄ　her fellow scientists still have a lot of work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

4、Shopping at Second - hａｎｄ　Clothing StoresWhen 33 year 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 mean 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 Slocum, 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 that waste from going to landfills (垃圾填埋场). They give clothing a second life, 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.What does Akins do? ______【单选题】

A.She is a soldier.

B.She is an accountant.

C.She is a saleswoman.

D.She is a road sweeper.

正确答案:B

答案解析:本题难度不大，答案依据不难找到。带着题干信息到文章定位，认真阅读文章第四段。第四段第一句话谈到，Akins是旧货店的一名会计，所以答案是B。

5、Dairy Price-fixing ScandalTesco is preparing a legal battle to clear its name of involvement in the dairy price-fixing scandal that has cost consumers ￡270 million. Failure to prove that it had no part in collusion with other supermarkets ａｎｄ　dairy processors may lａｎｄ　it with a fine of at least ￡80 million. The Office of Fair Trading (OFT) said yesterday that Asda, Sainsbury\'s ａｎｄ　the former Safeway, plus the dairy companies Wiseman, Dairy Crest ａｎｄ　Cheese Company, had admitted being in a cartel to fix prices fｏｒmilk, butter ａｎｄ　cheese. They were fined a total of just over ￡116 million as part of a leniency deal offered by the watchdog to companies that owned up quickly to anti-competitive behaviour.Officials at the OFT admitted privately that they did not think they would ever discover which company ｏｒindividual had initiated the pricing formula. But the watchdog recognises that at the time supermarkets were under pressure from politicians ａｎｄ　farmers to raise the cost of milk to save dairy farming, though it is not certain that money found its way to farmers. The OFT claimed in September that it had found evidence that the retail chains had passed future milk prices to dairy companies, which then reached a fixed price among themselves.The average cost to each household is thought to be ￡11.25 over 2002 ａｎｄ　2003, Prices went up an extra 3p on a pint of milk, 15p on a quarter of a pound of butter ａｎｄ　15p on a half pound of cheese. There is no direct recompense fｏｒconsumers, however, ａｎｄ　the money will go to the Treasury. The National Consumer Council gave warning that the admissions would dent consumer confidence in leading high street names ａｎｄ　that people would become sceptical of their claims. Farmers fｏｒAction, theｇｒｏｕｐof farmers that has led protests over low milk prices since 2000, is seeking legal advice on whether it can now bring a claim fｏｒcompensation.The OFT investigation is continuing, however, in relation to Tesco, Morrisons ａｎｄ　the dairyｇｒｏｕｐLactalis McLelland, ａｎｄ　any legal action is expected to be delayed until that is completed. Tesco was defiant ａｎｄ　said that it was preparing a robust defence of its actions. Lucy Neville-Rolfe, its executive director, said: "As we have always said, we acted independently ａｎｄ　we did not collude with anyone. Our position is different from our competitors ａｎｄ　we are defending our own case vigorously. Our philosophy is to give a good deal to customers."Morrisons has supported the OFT in inquiries into the former safeway business that it took over, but in a statement said that it was still making "strong representations" in its defence. A spokeswoman fｏｒLactalis McLellａｎｄ　said that the company was "co-operating" with the OFT. Industry insiders suggested that the three companies were deliberately stalling the OFT investigation.Sainsbury\'s admitted yesterday that it had agreed to pay ￡26 million in fines, but denied that it had sought to profiteer. Justin King, the chief executive, said he was disappointed that the company had been penalised fｏｒactions meant to help farmers but recognised the benefit of a speedy settlement. Asda declined to say how much it would pay in fines ａｎｄ　also said that its intention had been to help farmers under severe financial pressure.The word "defiant" (line 3, paragraph 4) most probably means ______.【单选题】

A.resisting

B.angry

C.deficient

D.confident

正确答案:A

答案解析:猜词题。根据上下文可以看出，Tesco声称自己正在为自己的行为准备最坚决的辩护，可见其采取一种抵抗的态度，对比四个选项，只有resisting符合此意。
