1、Cell Phone Lets Your Secret OutYour cell phone holds secrets about you. Besides the names ａｎｄ　numbers that you\'ve programmed into it, traces of your DNA linger on the device, according to a new study.DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you- because you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, ｏｒhair left behind at the scene of a crime. The results often help detectives identify ______ ａｎｄ　their victims. Your cell phone can reveal more about you than you might think.Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone ａｎｄ　later dropped the device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. So she ａｎｄ　colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs to collect invisible traces of the users from two parts of the phone: the outside, where the user holds it, ａｎｄ　the speaker, which is placed at the user\'s ear.The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back fｏｒanother week. Then the researchers collected the phones ａｎｄ　repeated the swabbing of each phone once more.The scientists discovered DNA that belonged to the phone\'s speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won\'t remove all traces of evidence from a criminal\'s device. So cell phones can now be added to the list of clues that can clinch a crime scene investigation.【单选题】

答案解析:根据上下文的理解，研究结果是用来帮助侦探识别罪犯和受害人的，B、C、D都不能表达这一层意思。

2、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 colｏｒ- changing material. It will turn red before a structure collapses ｏｒfalls apart.The secret behind the colｏｒ- changing material is a particular type of molecule (分子). A molecule is aｇｒｏｕｐof atoms (原子) held together by chemical bonds. Molecules come in 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 colｏｒ- changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces a color. When a polymer with mechanophore molecules becomes "injured" ｏｒ_____, 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 colｏｒ- changing polymers in their lab. The test results proved encouraging.There is a way to get rid of the red colｏｒlight. When a bright light is shone on the mechanophore, the broken bond is fixed ａｎｄ　the red colｏｒdisappears. Thus "self - healing" may be a problem fｏｒengineers. They need to use the colｏｒ- changer in big construction projects that will be outside, under sunlight. ａｎｄ　sunlight will make the mechanophore\'s warning system useless.Sottos ａｎｄ　her fellow scientists still have a lot of work to do before the colｏｒ- changing molecules can be used outside the lab.【单选题】

A.strong

B.soft

C.weak

D.hard

正确答案:C

答案解析:本题有一定难度，关键在理解好文章上下文意义，文章此处的or表明后面用词要和injured相近，答案是C。

3、The GuitarThe Museum of Fine Arts in the eastern city of Boston recently began showing a collection of guitars. The exhibit is called Dangerous Curves: The Art of the Guitar. It shows how the instrument developed during the past four centuries. Probably no other musical instrument is as popular around the world as the guitar. Musicians use the guitar fｏｒalmost every kind of music. Country ａｎｄ　western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. ａｎｄ　rock ａｎｄ　roll music would almost be impossible without this instrument. Music experts do not agree about where the guitar first was played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than a thousａｎｄ　years ago. Some other experts say that the ancestｏｒof the modern guitar was brought to Spain from Persia sometime in the twelfth century. The guitar continued to develop in Spain. In the seventeen-hundred it became similar to the instrument we know today. Many famous musicians played the instrument. The famous Italian violinist Niccolo Paganinni played ａｎｄ　wrote music fｏｒthe guitar in the early eighteen hundred. Franz Schubert used the guitar to write some ofhis famous works. One guitar in the Boston Fine Arts display was played by Les Paul. It is a very old electric guitar. Mister Parl began experimenting with ways to make an electric guitar in the nineteen-thirties. The Gibson Guitar Company began producing its famous Les Parl Guitar in 1952. The instrument has the same shape ａｎｄ　the same six strings as the traditional guitar, but it sounds very different. The guitar has always been important to blues music. The electric guitar Mister Paul helped develop made modern blues music possible. There have been many great blues guitarists. Yet, music experts say all blues guitar players are measured against one man ａｎｄ　his famous guitar. That man is B-B King. Every blues fan knows that years ago B-B King named his guitar Lucille. Lucille is so important to American music that the Smithsonian Institution in Washington D-C has asked fｏｒit. They want to display the large, beautiful black guitar in one of the museums because it is a part ofAmerican culture. John Denvｏｒis one of the specialists in playing the guitar. 【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:C

答案解析:本题说的是约翰丹佛，吉他演奏专家之一。文章提到了B-B King，但没有提及约翰丹佛，尽管我们知道他确实是吉他演奏专家。

4、The orangutanAmong all the animals, the ape is most like human beings. Both people ａｎｄ　apes have the similar brain structure, the similar nerve system, ａｎｄ　the similar kind of blood. There are four kinds of apes: the chimpanzee (黑猩猩), the orangutan (猩猩), the gorilla (大猩猩), ａｎｄ　the gibbon (长臂猿). They live in the deep forests ａｎｄ　warm tropical regions of Africa ａｎｄ　of Southeast Asia, including Indonesia. All apes are covered with brown, reddish-brown, ｏｒblack hair everywhere on their bodies except their faces, feet, ａｎｄ　hands. Their hands each have four fingers ａｎｄ　a thumb that helps them grip things the way our thumbs help us. But they also have a thumb on each foot instead of a big toe. Thus they can hold things with their feet also. Having short, weak legs, apes do not walk on the ground very much. However, their arms are very strong. This enables them to swing from branches ａｎｄ　travel very quickly from tree to tree. These animals live in small family groups that move from place to place in search of vegetables ａｎｄ　fruits. They also eat eggs, small animals, nuts, ａｎｄ　insects. When they are tired, they build nests in the trees. But they rarely sleep there fｏｒmore than a night ｏｒtwo. Then they move on to look fｏｒmore food. There are some differences among the following three kids of apes. The gibbon is never more than three feet high ａｎｄ　weight only about fourteen pounds. The gorilla grows to be six feet tall ａｎｄ　weight up to 600 pounds. The orangutan is smaller than the gorilla. It stands three to five feet tall ａｎｄ　weight up to 200 pounds. Chimpanzees are the smartest of all apes. They can be taught to sit at a table ａｎｄ　eat, to dress themselves, ａｎｄ　to do things that human children can do. Which of the following sentences is TRUE?【单选题】

A.All apes are brown ｏｒblack.

B.All parts of apes\' bodies are covered with hair.

C.Apes have weak legs but very strong arms.

D.Apes\' arms are strong enough to swim.

正确答案:C

答案解析:由文章第3段倒数第2句和第3句可知，猿的腿短而无力，但手臂很强壮，故选C。倒数第1句说强壮的手臂使得猿能够swing而不是swim，排除D。由该段第1句和第2句可排除A、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.We may infer from Morrisons\' statement that ______.【单选题】

A.Morrisons was uncooperative with OFT

B.Morrisons was reluctant to support the inquiries into the former safeway business

C.Morrisons was trying to delay the OFT investigation

D.Morrisons was working hard to defend its interests

正确答案:D

答案解析:推理题。注意句中but表示的转折关系。行动上是一种合作态度，但还是要竭力维护自己的利益，故正确答案为D。

6、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, ａｎｄ　coordination between hands ａｎｄ　the brain. Many human drivers have all. these ａｎｄ　can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" ａｎｄ　"feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road ａｎｄ　conditions ahead of it. They watch the traffic to the car\'s left ａｎｄ　right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it ａｎｄ　analyzes their positions. Basing on this information, it chooses the right line fｏｒthe intelligent cars, ａｎｄ　gives instructions to the "hands" ａｎｄ　"feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver ______ needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time ａｎｄ　in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】

A.at least

B.at most

C.at last

D.at best

正确答案:A

答案解析:选项B和D是近义短语结构，因此相互排除掉。空白所在的句子说“然而，世界上最好的司机作出反应……需要1秒钟”，因此判断A（至少）是答案。第60题和第61题所在的句子把“虚拟司机”和“人类最好的司机”进行反应速度的对比（虚拟司机反应速度快），显然这是利用具体事实的分析以论证该段开头部分的观点句(He reacts quickly)，由此进一步肯定第58题的答案是quickly。

7、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to _____ the killer virus in the last two labs, one in the US ａｎｄ　one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). ａｎｄ　the last "official" stocks of live Virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines(疫苗). So once again there\'s a good reason to the virus, just in keep the disease puts in a reappearance.How do we case with the mistrust of the US ａｎｄ　Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn\'t mean the idea is rejects. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【单选题】

A.destroy

B.improve

C.change

D.transport

正确答案:A

答案解析:本题有一定难度，考查词义辨析，干扰项有一定的干扰。文章此处是说“当天花病毒从世界上完全被消灭时，科学家也想消灭在最后两个实验室拥有的这种致命病毒”，此处要用“消灭”的意思，答案是A。
