1、Arctic MeltEarth\'s North and South Poles are famous forbeing cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But formany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drepin end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. and it\'s a very large 23 percent below the previous record low, which was setjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons forthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.It can be learned from the last sentence that ______.【单选题】
A.the ice melt in the Arctic may never stop
B.scientists are trying hard to stop the ice melt in the Arctic
C.scientists are delighted to find out what is going on in the Arctic
D.the warming trend in the Arctic can be reversed in the near future
正确答案:A
答案解析:本题难度不大,最后一句话的句意不难理解。文章最后一句谈到,科学家们担心北极处于变暖趋势,而且不能挽回,答案是B。
2、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。
3、Animal\'s "Sixth Sense"A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" fordisasters, experts said.Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island\'s coast clearly missed wild beasts, with no dead animals found."No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy directorof Sri Lanka\'s Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka\'s biggest wildlife reserve and home to hundreds of wild elephants and several leopards."There has been a lot of scientific evidence about dogs barking orbirds migrating before volcanic eruptions orearthquakes. But it has not been proven," said Matthew van Lierop, an animal behaviorassistant at Johannesburg Zoo. "There have been no specialist studies because you can\'t really test it in a lab orfield setting," he told Reuters. Other authorities concurred with this assessmetn."Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.Animals ______ rely on the known senses such as smell orhearing to avoid danger such as predators. The notion of an animal "sixth sense" -orsome other mythical power-is an enduring one which the evidence on Sri Lanka\'s ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers orattributes.【单选题】

4、How to Interview PeopleInterviewing (采访) is one of those skills that you can only get better at. You will never again feel so ill at ease when you try it forthe first time, and probably you\'ll never feel entirely comfortable trying to get from another person answers that he orshe may be too shy to reveal. But at least half of the skill is mechanical. The rest is instinct, which can all be learned with experience.The basic tools foran interview are paper and two orthree well-sharpened pencils. But keep your notebook orpaper out of sight until you need it. There\'s nothing less likely to relax a person than the arrival of someone with a note-taking pad. Both of you need time to get to know each other. Take a while just to chat, judging what sort of person you\'re dealing with, getting him orher to trust you.Never go into an interview without doing whatever homework you can. If you are interviewing a town official, know his voting record. If it\'s an actor, know what plays he has been in. ______Many beginning interviewers are afraid that they are forcing the other person to answer questions and have no right to inquire about his personal secrets. This fear is almost 103 percent unnecessary. Unless the person really hates being interviewed, he is delighted that somebody wants to interview him. Most men and women lead lives that are uninteresting, and they grasp any chance to talk to an outsider who seems eager to listen.This doesn\'t necessarily mean that it will go well. In general you will be talking to people who have never been interviewed before, and they will get used to the process awkwardly, perhaps not giving you anything that you can use. Come back another day; it will go better. You will both even begin to enjoy it-proof that you aren\'t forcing your victim to do something he doesn\'t really want to.【单选题】
A.Come back another day; it will go better.
B.But at least half of the skill is mechanical.
C.As one philosopher interviewed in the film notes, they lack irony.
D.You will not be liked if you inquire about facts that you could have learned in advance.
E.This fear is almost 102 percent unnecessary.
F.Both of you need time to get to know each other.
正确答案:D
答案解析:空句前一直在说要提前进行准备,If it\'s an actor, know what plays he has been in,当然如果在采访一个人之前对被采访者没有任何了解肯定不会受欢迎。

7、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" 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 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 _____ work to do before the color- changing molecules can be used outside the lab.【单选题】
A.a pair of
B.a type of
C.a lot of
D.a part of
正确答案:C
答案解析:本题难度不大,考查词义辨析。文章此处是说“Sottos和同事们还有很多工作要做”,答案是C。

9、Inventorof LEDWhen Nick Holonyak setout to create a new kind of visible lighting using semiconductoralloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, orLEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights and other everyday technology. On April 23,2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the lOth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. "Anytime you get an award big orlittle. It\'s always a surprise. " Holonyrak said. Holonyak, 75, was a student of john Bardeen, an inventorof the transistor, in the early 1950s. After graduate school, Holonyak worked at Ben Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches. Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and effective. Holonyak, now a professorof electrical and computer engineering and physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn\'t realize how many uses they would have. "You don\'t know in the beginning. You think you\'re doing something important. You think it\'s worth doing, but you really can\'t tell what the big payoff is going to be, and when, and how. You just don\'t know, "he said. The Lemelson. MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award forher work on a new generation of "molecular sieves", that can separate molecules by size. Edith Flanigen is the only co-inventorof LEDs.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:C
答案解析:题干中出现的特征词Edith Flanigen作为答案线索,发现答案相关句,内容是说Edith Flanigen对新一代的“分子筛”的研制做出了杰出的工作,但没有说她是LEDs的合作发明者。
