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 at 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 ______ 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】

A.closes

B.breaks

C.increases

D.bums

正确答案:B

答案解析:前文为bond，意为联系，后文说到变红，说明不是在常态之下，那么联系是常态，联系断开才与红相对应，所以选break。

2、Lakes, Too, Feel Global WarmingThere\'s no doubt, In the last few decades, the average temperature on Earth has been higher than it has been in hundreds of years. Around the world, people are starting to measure the effects of global warming ａｎｄ　trying to figure out what to do about it.Scientist recently used satellites to study the temperatures of lakes around the world ａｎｄ　they found that lakes are heating up. Between 1985 ａｎｄ　2009, satellites recorded the night time temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius in just 10 years. That difference may seem small you might not even notice it in your bath. But in a lake, slightly warmer temperatures could mean more algae (水藻) ａｎｄ　algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming. The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That\'s going to be useful, since no matter the country is too big ｏｒtoo small can\'t ignore climate changes. Scientists aren\'t the only ones concerned. Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse(温室) gases we put into the air.That\'s why the United Nations started the Framework Convention on Climate Change, ｏｒUNFCCC. Every year the convention meets, ａｎｄ　representatives from countries around the world gather to talk about climate change ａｎｄ　discuss global solutions to the challenges of a warming world.Scientists generally focus on air temperatures when studying global warming.【单选题】

5、Light Night, Dark StarsThousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, ｏｒartificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文学家) with the University Corporation fｏｒAtmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they\'re lucky to see 150 stars.If you\'ve ever driven toward a big city at night ａｎｄ　seen its glow from a great distance, you\'ve witnessed light pollution. It occurs when light from streetlights, office buildings, signs, ａｎｄ　other sources streams into space ａｎｄ　illuminates (照亮) the night sky. This haze (朦胧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.Dust ａｎｄ　particles of pollution factories ａｎｄ　industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."Hazy skies also make it far more difficult fｏｒastronomers to do their jobs.Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使变模糊) the faint (微弱的) light give off by distant stars. ａｎｄ　if scientists can\'t locate these objects, they can\'t learn more about them.Light pollution doesn\'t only affect star visibility. It can harm wild life too. It\'s clear that artificial light can attract animals, making them go off course. There\'s increasing evidence, fｏｒexample, that migrating (迁徙) birds use sunsets ａｎｄ　sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破坏性的) influence." Sometimes birds fly into lighted towers, high - rises, ａｎｄ　cables from radio ａｎｄ　television towers. Experts estimate that millions of birds die this way every year.On a clear night, people can see ______.【单选题】

A.150 stars

B.hundreds of stars

C.one thousａｎｄ　stars

D.more than 14,000 stars

正确答案:D

答案解析:本题难度不大，答案依据比较明显，在文章第一段第二句，这句话主要谈到，在晴朗的夜晚人们能看到14，000多颗星星，回来看选项，D项符合原文句意，是答案。

6、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 ______ 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 certainly 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】

A.waves

B.tides

C.winds

D.rivers

正确答案:A

答案解析:本句说的是海的巨浪将洪水带到离海岸远超2英里的东南部内陆Yala国家公园。正确答案应该是waves。

7、Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle event-flowering, the appearance of leaves, the first frog calls of the spring all around the world. But ecologists can\'t be everywhere so they\'re turning to non-scientists, sometimes called citizen scientists, fｏｒhelp. Climate scientists are not present everywhere. Because there are so many places in the world ａｎｄ　not enough scientists to observe all of them, they\'re asking fｏｒyour help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people too observe a very specific research interest-birds, trees, flowers budding, etc. ａｎｄ　send their observations to a giant ｄａｔａｂａｓｅ to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready fｏｒthe conditions where they live. All that\'s needed to become one is a few minutes each day ｏｒeach week to gather data ａｎｄ　send it in. Aｇｒｏｕｐof scientists ａｎｄ　educators launched an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group\'s first efforts relies on scientists ａｎｄ　non-scientists alike to collect data about plant flowering ａｎｄ　leafing every year. The program, called Project BudBurst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone record their observations on the Project BudBurst website. "People don\'t have to be plant experts, they just have to look around ａｎｄ　see what\'s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we\'ll be able to make an estimate of how plants ａｎｄ　communities of plants ａｎｄ　animals will respond as the climate changes. "What is NOT true of Project BudBurst?【单选题】

A.Only experts can participate in it.

B.Everybody can participate in it.

C.It collects life cycle data on a variety of common plants.

D.It has its own website.

正确答案:A

答案解析:文章全文都在说普通人参与科学研究的项目，因此只有选项A不符合。其他选项都能在文中找出。

A.results

B.rules

C.tools

D.methods

正确答案:A

答案解析:本题难度不大，考查的是词义辨析。很明显，文章此处的意思是“结果”，答案是A。

9、Radiocarbon DatingNowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), ｏｒcarbon - 14 dating. One key to understanding how ａｎｄ　why something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) ａｎｄ　six neutrons (中子) in its nucleus (原子核). Carbon - 14, ｏｒC - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons ａｎｄ　energy from the nucleus.In Libby\'s radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detectｏｒａｎｄ　counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.Carbon - 14 is produced in the Earth\'s atmosphere when nitrogen(氮) - 14, ｏｒN - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful fｏｒdating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, ａｎｄ　the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases ａｎｄ　the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.An atom of ordinary carbon has. six protons ａｎｄ　eight neutrons.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题难度不大，答案依据比较明显，主要答案依据在文章第二段第二句：An atom of ordinary carbon，called carbon - 12，has six protons ａｎｄ　six neutrons谈到普通碳原子有6个质子和6个中子，显然，题干和答案依据不符，答案是B。

10、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.All the following advantages of advertising are mentioned in the first paragraph except that____.【单选题】

A.it raises standards of living

B.it reduces the cost of many services

C.it makes products much better

D.it provides more jobs

正确答案:C

答案解析:提高生活水平、降低许多服务成本、提供更多岗位在第1段中都可以找到，因此选C。
