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 criminals 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. ______, 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】
A.Generally
B.Surprisingly
C.Disappointedly
D.Shortly
正确答案:B
答案解析:最后一段的第一和第二句告诉我们手机经过清洗后仍然有微量DNA出现。所以这里要用surprising这个副词,表示令人惊讶。
2、If headaches only occur at night, lack of fresh air is often the cause.【单选题】
A.deliver
B.fall
C.happen
D.arrive
正确答案:C
答案解析:题干大意:如果只是晚上头疼,那是因为缺氧。画线词occur:发生。选项中,happen:发生,和画线词一样都是不及物动词,因此可替换。deliver:传递。如:No time to chat. Urgent messages to deliver. 没有时间闲聊。有紧急信息要传送。fall:落下,跌倒。如:They might bump into things orfall over objects. 他们有可能撞到或跌倒在某些物体上。arrive:到达。如:Remember to call us when you arrive. 记得到达后给我们打电话。
3、The carCars are an important part of life in the United States. Without a car most people feel that they are poor. and even if a person is poorhe doesn\'t feel really poorwhen he has a car. Henry Ford was the man who first started making cars in large numbers. He probably didn\'t know how much the car was going to affect American culture. The car made the United Stated a nation on wheels. and it helped make the United States what it is today. There are three main reasons why the car becomes so popular in the United States. First of all, the country is a huge one and Americans like to move around in it. The car provides the most comfortable and cheapest form of transportation. With a car people can go anylace without spending a lot of money. The second reason cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long-distance trains have never been as common in the country as they are in other parts of the world. Nowadays there is a good system of air-service provided by planes. But it is too expensive to be used frequently. The third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don\'t like to wait fora bus, ora train oreven a plane. They don\'t like to have to follow an exact schedule. A car gives them the freedom to schedule their own time. and this is the freedom that Americans want most to have. The gas shortage has caused a big problem forAmericans. But the answer will not be a bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much gas. "A nation on wheels" means that____. 【单选题】
A.the country is producing the best cars in the world
B.everyone in this country owns a car
C.cars play a very important role in people\' lives
D.there are more cars than trains in this country
正确答案:C
答案解析:原文“The car made the United Stated a nation on wheels”说明,在美国汽车很受欢迎,汽车对于美国人来说是非常重要的。
4、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. ______Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron fora month. They found that 100 years later only between 2 and 13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer and better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same. Ocean fertilization is not the answer to global warming."【单选题】
A.Its opponents argue, however, that it will stop global warming.
B.Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.
C.As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.
D.They found that 100 years later only between 2 and 11 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.
E."These are newer and better models,"
F.Ocean fertilization is not the answer to global warming.
正确答案:B
答案解析:前句的句意(可以直接借助句子中的核心结构判断句子大意):“一些人鼓励浮游生物在海洋里生长,认为这有希望从大气中去除二氧化碳”,B中的opponents fear和空白前句中的some. . . encourage形成语意对比。
5、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.

8、Medicine Award Kicks off Nobel Prize AnnouncementsTwo scientists who have won praise forresearch into the growth of cancer cells could be candidates forthe Nobel Prize in medicine when the 2008 winners are presented on Monday, kicking off six days of Nobel announcements. Australian-born U. S. citizen Elizabeth Blackburn and American Carol Greider have already won a series of medical honors fortheir enzyme research and experts say they could be among the front-runners fora Nobel. Only seven women have won the medicine prize since the first Nobel Prizes were handed out in 1901. The last female winner was U. S. researcher Linda Buck in 2004, who shared the prize with Richard Axel. Among the pair\'s possible rivals are Frenchman Pierre Chambon and Americans Ronald Evans and Elwood Jensen, who opened up the field of studying proteins called nuclear hormone receptors. As usual, the award committee is giving no hints about who is in the running before presenting its decision in a news conference at Stockholm\'s Karolinska Institute. Alfred Nobel, the Swede who invented dynamite, established the prizes in his will in the categories of medicine, physics, chemistry, literature and peace. The economics prize is technically not a Nobel but a 1968 creation of Sweden\'s central bank. Nobel left few instructions on how to select-winners, but medicine winners are typically awarded fora specific breakthrough rather than a body of research. Hans Jornvall, secretary of the medicine prize committee, said the 10 million kronor(US$1. 3 million) prize encourages groundbreaking research but he did not think winning it was the primary goal forscientists. "Individual researchers probably don\'t look at themselves as potential Nobel Prize winners when they\'re at work," Jornvall told The Associated Press. "They get their kicks from their research and their interest in how life functions. "In 2006, Blackburn, of the University of California, "San Francisco, and Greider, of Johns Hopkins University in Baltimore, shared the Lasker prize forbasic medical research with Jack Szostak of Harvard Medical School. Their work setthe stage forresearch suggesting that cancer cells use telomerase to sustain their uncontrolled growthThe word "kicks" in line 6 from the bottom probably means____. 【单选题】
A.excitement.
B.income.
C.motivation.
D.knowledge.
正确答案:A
答案解析:从上下文不难看出,科学家搞研究的主要目的不是为了获奖,他们从其所从事的研究及生命运行的兴趣中获得很大快感。

10、Why Would They Falsely Confess?Why on earth would an innocent person falsely confess to committing a crime? To most people, it just doesn\'t seem logical. But it is logical, say experts, if you understand what can happen in a police interrogation room.Under the right conditions, people\'s minds are susceptible to influence, and the pressure put on suspects during police grilling is enormous. ______ "The pressure is important to understand, because otherwise it\'s impossible to understand why someone would say he did something he didn\'t do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess."Developmental psychologist Allison Redlich recently conducted a laboratory study to determine how likely people are to confess to things they didn\'t do. In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems. The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.Redlich\'s findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed. Redlich also found that the younger the participant, the more likely a false confession. Of the 15-to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds."There\'s no question that young people are more at risk," says Saul Kassin, a psychology professorat Williams College, who has done similar studies with similar results, "But adults are highly vulnerable too."Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-and still, most participants falsely confessed.Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. "In some ways," says Kassin, "false confession becomes a rational decision."【单选题】
A.In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems.
B."In some ways," says Kassin, "false confession becomes a rational decision."
C."It\'s a little like somebody\'s working on them with a dental drill," says Franklin Zimring, a law professorat the University of California at Berkeley.
D."But adults are highly vulnerable too."
E.How could an innocent person admit to doing something he didn\'t do?
F.Redlich also found that the younger the participant, the more likely a false confession.
正确答案:C
答案解析:解答此题时要注意,空格后是一段引文,而空格前又没有引文,所以此空格处一定是引用了某人的话,因此答案只可能在B、C、D中。但D只是一句引用的话,并没有提及是谁说的,这不符常理,故排除。B虽然提到了Kassin,但没有对其身份进行说明,这也不符“第一次提到某人时要有说明”的习惯(实际上他出现在第五段),故排除B。因此只能选C,从内容上看也符合。
