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 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 _____ 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 a lot of work to do before the color- changing molecules can be used outside the lab.【单选题】

D.where
正确答案:C
答案解析:本题难度不大,考查宾语从句引导词what的用法,本题可以先看选项,得到信息提示,很明显,答案是C。
2、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. ______ 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】
A.However
B.So
C.But
D.Nevertheless
正确答案:B
答案解析:四个选项中只有B是正确选择,连接了其前后两个句子,使其形成因果关系:她思考微量DNA是否会停留在手机上,所以,她与同事们一起对10名志愿者的翻盖手机进行了分析研究。A、C、D都是转折的意义关系。
3、What Do Dreams Tell Us?Why do we dream? Do dreams have meanings? These are questions which have troubled man forthousands of years. The oldest surviving book on the interpretation of dreams is Egyptian and is nearly 4,000 years old. In ancient Greece, it was thought that people who were ill could be cured by telling their dreams. They would relate their dreams to their doctors who would tell them what they meant and then give them medicine to make them well. The ancient Chinese believed that if a pregnant woman dreamed of a bear, she would have a son, and if she dreamed of a snake, she would have a daughter. There are many stories about dreams foretelling (预言) the future.We certainly do not now believe that dreams foretell the future. Most scientists believe that dreams are based on events in our own life and on our feelings. The events are usually very recent, mostly within the last two days. Our emotions, on the other hand our wishes, hopes and fears may go back many years, even to early childhood.In a dream, events are altered. A dream may contain parts of many real-life events. Most importantly, something that cannot be shown directly may be shown indirectly. Forexample, you might dream of driving a large car. This could mean not that you want to have a larger car, but that you desire power, and maybe you want to control other people. Again, you may dream that you are an actorin a play. The play is about to start, but you have completely forgot your lines. This dream may seem strange because you are not interested in acting, and you never want to be in a play. But the dream may mean that you have some other problem that you feel is too difficult foryou to solve.Psychologists believe that dreams may be helpful to us. Indeed, people who have been allowed to sleep in experiments, but not allowed to dream, have become anxious and restless. and when they are later allowed to sleep as much as they like, they dream more than ever to make us forthe lost "dream time". Paragraph 1 ______.【单选题】
A.Structure and interpretation of a dream
B.Ancient views on dreams
C.Babies dream less than older children
D.Dreaming may be good forour health
E.Dreams can not foretell the future
F.Healthy people do not dream
正确答案:B
答案解析:第一段主题句为第三句:These are questions which have troubled man forthousands of years. 这些问题已经困扰了人类几千年。段中则分别提到了古代埃及、希腊和中国对梦的理解。而B选项Ancient views on dreams(古人对梦的观点)与其意思一致,故B为正确答案。
4、Dung to DeathFields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs". The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry ______Some 20,000 tons of antibiotics are used in the European unionand the US each year. More than half are given to farm-animals to prevent disease and promote growth. But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people. Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end. up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute forEnvironmental Science and Technology in Dubendorf. and manure contains especiaily high levels of bugs that are resistant to antibiotics he says.With millions of tons of animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route forspreading resistance, he said. The drugs contaminate the crops, which are then eaten. They could also be leaching into tap water pumped from rocks beneath fertilized fields.Mueller is particularly concerned about agroupof antibiotics called sulphonamides. They do not easily degrade ordissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously. There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged and are not broken down by conventional sewage treatment.【单选题】
A.They do not easily degrade ordissolve in water.
B.and manure contains especiaily high levels of bugs that are resistant to antibiotics he says.
C.Animal antibiotics is still an area to which insufficient attention has been paid
D.But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.
E.His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.
F.They could also be leaching into tap water pumped from rocks beneath fertilized fields.
正确答案:E
答案解析:本句中包含he这个代词,故上文中必定有它的先行词,his findings又表明此人应该是从事科研工作的,句中又提到Switzerland,考虑这种种因素,填入E是正确的。
5、Will We Take Vacation in Spaces?When Mike Kelly first setout to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits fora two-hour, $98, 000 space tour tentatively and somewhat dubiously (可疑地) setto actorby 2005. Gene Meyers of the space Island Group says: "Space is the next exotic(风光奇特的) vacation spot. "This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support orreturn trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. and that doesn\'t include the oust of insuring rich and possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entiregroupof entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive forthe little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe and reliable. Kelly Space\'s prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles and an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can\'t be too prepared, fora trip to that galaxy far, far away. Forthose who are intent on joining the 100-mile high club, Hilton and Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, and if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite. It sounds great that soon there will be space residence, although it is still a tentative plan. 【单选题】
A.Right
B.Wrong
C.Notmentioned
正确答案:C
答案解析:文中没有提及与此相关的信息,文章只提及了太空旅行的相关情况及发展前景,并未提及在太空定居。
6、Meet Your Memory1. Memory is something that cannot be seen, touched orweighed. It is thought to be abstract. It is a setof skills rather than an object. Neither is there a single standard forjudging a good orpoormemory. There are a number of different ways in which a person may have a good memory.2. Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the brain until it is needed; (3) retrieval (提取) refers to getting the material back out when it is needed:3. Memory consists of at least two different processes: short - term memory and long - term memory. Short - term memory has a limited capacity and a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), orgrouping separate bits of information into larger chunks. Long - term memory has an almost unlimited capacity.4. One measure of memory is recall, which requires you to produce information by searching the memory forit. In aided recall, you are given cues (提示) to help you produce the information. In free - recall learning you recall the material in any order. In serial learning you recall it in the orcerit was presented and in paired - associate learning you learn pairs of words so that when the first word is given you can recall the second word. A second measure of memory is recognition, in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time and how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Paragraph 4 ______【单选题】
A.Why do we forget things?
B.How do we measure memory?
C.What are the stages memory consists of?
D.What is the difference between short - term memory and long - term memory?
E.What is memory?
F.Who may have a poormemory?
正确答案:B
答案解析:本题有一定难度,没有明显的主旨句,需要较强归纳能力。文章第四段主要论述了测量记忆力的三种方法,回来看选项,B项How do we measure memory?简单概括了本段主要意思,是答案。
7、The Value of AdvertisementMoney spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide forexport at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need forlabor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus orsubway would cost more. and perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people fora little while through misleading advertising. He will not do so forlong, forthe public has the good sense not to buy the poorgoods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised forit, and that it has good value. Advertising does more forthe good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its messages were nothing but information, that would be difficult to get more people to buy, foreven the choice of the colorof a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.Which of the following is the most important advantage according to the passage?【单选题】
A.Reducing the cost of your daily newspaper.
B.Lowering the price of your television program.
C.Making it possible to provide forexport at good price.
D.Providing a promise of reasonable value in the products and services you buy.
正确答案:D
答案解析:选项A、B、C、D都是提到的好处,但是从文章第2段第1句可知,最重要的是广告能提供产品和服务的价值承诺。因此选D。
8、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack orstroke later in life and could prevent hundreds of ______ of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections and allergies and are less prone to obesity. British scientists have now shown that breastfeeding and slow growth in the first weeks and months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol and increasing their tendency to diabetes and obesity-the four main risk factors forstroke and heart attack." said ProfessorAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure and cholesterol later in life are greater than anything adults can do to control the risk factors forcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack and strokes, each year, according to the World Health Organization. Lucas and his colleagues compared the health of 216 teenagers who as babies had either been breastfed orgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol and lower concentrations of a protein that is a marker forcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks and months of life, the greater was their later risk of heart disease and stroke. The effect was the same forboth boys and girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【单选题】
A.hundreds
B.thousands
C.millions
D.numbers
正确答案:B
答案解析:hundreds ofthousands of是固定搭配,表示“成千上万”之意。
9、Houses of FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict what our home will be likeE. Future houses will have to be flexible. In thirty years\' time even more of us will be working at home. So we will have to be able to use areas of the house forwork forpart of the day and forliving forthe rest. Families grow and change with children arriving, growing up and leaving home. The house ofthe future will have to grow and change with the familyF, nothing will be as fixed as it is now. The house will always be changing to meet changing needs. Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "we\'ll be having a party this weekend. What food shall we cook?" and the machine will tell us what food we will have to buy and how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check. The house of the future will be personal-each house, you will be able to change the colorofthe wall easily, you won\'t have to paint them, you\'ll be able to tell the wall to change the color! and if you don\'t like the colorthe next day, you will be able to have a new one. ______.【单选题】

D.what our home will be likeE
E.The house ofthe future will have to grow and change with the familyF
F.he kids might take their bedrooms with them as they have
正确答案:B
答案解析:意思是“也许唯一一件你不能改变的事就是把房子移到其他地方去而已”,与上文中可以随心所欲做任何事相符。
10、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all.______ 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 at least 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.these
B.them
C.this
D.that
正确答案:A
答案解析:根据all的习惯搭配:all+指示代词,因此首先排除B(人称代词)。结合前句内容,空白处的代词应该指代前句中提到的“敏锐的眼睛和耳朵、反应迅速的大脑、手和大脑之间的协调”,因此应该选择指代复数的指示代词these。
