1、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. "Ecologists turn to non-scientist citizens fｏｒhelp because they need them____. 【单选题】

A.to provide their personal life cycles

B.to observe the life cycle of plants

C.to collect data of the life cycle of living things

D.to teach children knowledge about climate change

正确答案:C

答案解析:前文提到科学家们没有可能去观察每一个地方的气候变化现象，所以邀请普通人为他们观察、收集信息。

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 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 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 colｏｒswitching polymers in their lab. The test ______ 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.results

B.rules

C.tools

D.methods

正确答案:A

答案解析:本句意为其实验结果令人振奋，所以应选results。

3、There is no risk to public health. 【单选题】

A.point

B.danger

C.chance

D.hope

正确答案:B

答案解析:risk和danger同义，危险的；point：某一想法；chance：机会；hope:希望。

4、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 ______ 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.selects

B.completes

C.uses

D.tests

正确答案:B

答案解析:空白所在的句子说“它在100毫秒的时间里……图像的处理”，根据该句内容判断B（完成）是答案。

5、Houses of the FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict. _____Future houses will have to be flexible. In thirty years\' time even more of us will be working from 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 of the future will have to grow ａｎｄ　change with the family. 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 will be different. You will be able to change the colｏｒof the 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. The only thing you won\'t be able to do is move the house somewhere else!【单选题】

A.You will be able to change the colｏｒof the wall easily.

B.The only thing you won\'t be able to do is move the house somewhere else!

C.ａｎｄ　the machine will tell us what food we will have to buy ａｎｄ　how to cook it.

D.What will our home be like then?

E.The house of the future will have to grow ａｎｄ　change with the family.

F.The kids might take their bedrooms with them as they leave.

正确答案:D

答案解析:本题的难度较大。需要认真阅读文章，特别是第一段和第二段，可用排除法和代入法。本题的上文谈到了没有人会知道30年后房子是什么样子，但建筑家们正在努力地预测。开头第一句用的是疑问句，下文的第一句就谈到未来的房子要十分灵活，用的是陈述句，可以推测此处很可能继续对未来房屋进行发问来展开文章的叙述，回来看选项，可以先排除A，B，C，F项，把D，E代入文章里，可以发现，D更能符合上下文语境和逻辑，是最佳答案。

6、A Great Quake Coming?Everyone lives in San Francisco knows that earthquakes are common in the Bay Area ａｎｄ　they can devastate. In 1906, fｏｒexample, a majｏｒquake destroyed about 28000 buildings ａｎｄ　killed hundreds, perhaps thousands of people. Residents now wonder when will the next "Big One" strike. It\'s bound to happen someday. At least seven active fault(断层) lines run through the San Francisco area. Faults are places where pieces of Earth\'s crust (地壳) slide past each other. When these pieces slip, the ground shakes.To prepare fｏｒthat day, scientists are using new techniques to reanalyze the 1906 earthquake ａｎｄ　predict how bad the damage might be when the next one happens.One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture(断裂) about 2.7 kilometers persecond. During bigger quakes, however, ruptures can happen faster than 3.5 kilometers persecond.At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky fｏｒSan Francisco, these pressure pulses (脉冲) traveled away from the city during the 1906 event.Looking ahead, scientists are trying to predict when the next majｏｒquake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a majｏｒearthquake striking the Bay Area before 2032 is at least 62 percent.New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city\'s buildings are old ａｎｄ　weak. Analyses suggest that another massive earthquake would cause extensive damage.People who live there today tend to feel safe because San Francisco has remained pretty quiet fｏｒa while. According to the new research, however, it\'s not a matter that whether "the Big One" will hit here. It\'s just a matter of when.The highest speed of fault ruptures in the 1906 quake was more than 3,5 kilometers per second.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题难度不大，找到答案依据不难。答案依据在第三段。第三段最后一句：During bigger quakes, however, ruptures can happen at rates faster than 3.5 kilometers per second.谈到在更大的地震中，断裂速度可以高于3.5千米每秒。所以本题正确，答案是A。

7、The Book of LifeSo far, scientists have named about 1.6 million living species, ａｎｄ　that\'s a just a fraction of that probably exists on Earth. With so many plants, animals ａｎｄ　other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg ｏｒwhat kind of bird is flying by.A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.To get the encyclopedia started, the creators will use information from scientific ｄａｔａｂａｓｅs that already exist. ａｎｄ　eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, fｏｒexample, will be able to input which bird they\'ve seen ａｎｄ　where. The technology fｏｒthis kind of tool has only become available.As the EOL develops, you might find it useful fｏｒschool projects. The site will feature special pages fｏｒkids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven\'t been reviewed.Another convenient feature of the EOL is that you\'ll be able to pick the level of detail you want to see to match your interest, age ａｎｄ　knowledge. If you wanted to learn about bears fｏｒa science class report, fｏｒexample, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature ａｎｄ　exploration of bears.It now takes years fｏｒscientist to collect all the data they need to describe ａｎｄ　analyze species. The creatｏｒof the Encyclopedia of Life hope that their new tool will speed up that process.Which of the following statement is NOT true? ______【单选题】

A.The EOL will be beneficial to school kids with its development.

B.Scientists will review every piece of the information added to EOL.

C.Scientists have cataloged only a small part of the living species.

D.People with different interests ａｎｄ　knowledge will in a way find EOL useful.

正确答案:B

答案解析:本题有一定难度，需要通读全文，寻找答案依据。答案依据主要在文章第四段倒数第二句：To make sure the encyclopedia is accurate．scientists will review much of the information added to it．显然，科学家是review much of the information，而不是every piece of the information，选项B项和原文句意不符，是答案。

8、Would you please call my husbａｎｄ　as soon as possible?【单选题】

A.visit

B.phone

C.consult

D.invite

正确答案:B

答案解析:麻烦您尽快给我丈夫打个电话好吗？本题难度不大，考查的是引申意义，call和phone做动词用，引申意义都有“打电话”的意思，是近义词，其他选项都是常用词汇，和答案意义差异大，最佳答案是B。

9、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 ______ 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.additional

B.specific

C.especial

D.exceptional

正确答案:B

答案解析:本段的第一句是说明为什么这些迹象(evidence)没有得到科学验证。原因是科学家无法在实验室或野外进行特定的实验，以验证动物预见灾难的第六感觉。理解了上下文的意思，就知道选specific是最合适的。其他的三个选项的词义与上下文不符合，additional，especial和exceptional分别是“额外的”、“特别的”和“例外的”的意思。

10、Snow RangerThe two things, snow ａｎｄ　mountains, which are needed fｏｒa ski area are the two things that cause avalanches, large mass of snow ａｎｄ　ice crushing down the side of a mountain, often called "White Death. "It was the threat of the avalanche ａｎｄ　its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937, 38 at Alta, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 ａｎｄ　another 200 died in 1937 as a result of avalanches before it became a majｏｒski area. Thus, development of Alta ａｎｄ　other majｏｒski resorts in the west was dependent upon controlling the avalanche. The Forest Service ｓｅｔout to do it, ａｎｄ　did with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier ａｎｄ　a skilled mountain climber. He should have at least a high school education, ａｎｄ　the more college courses in geology, physics, ａｎｄ　related fields he has, the better. He studies snow, terrain, wind, ａｎｄ　weather. He learns the conditions that produce avalanches. He learns to forecast avalanches ａｎｄ　to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, ａｎｄ　by the difficult ａｎｄ　skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety fｏｒpeople on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, ｏｒtalks with the ski area\'s operatｏｒas he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes. The passage implies that a snow ranger____. 【单选题】

A.knows how to use a pistol.

B.must write lengthy reports on his work.

C.may travel many miles when he is on duty.

D.has a long working day.

正确答案:C

答案解析:A:知道怎样使用手枪；B：必须写有关其工作的长篇报告；C：值班时可能会滑行数英里；D：工作时间很长。依据常识和已有的对文章的了解推断C最合理。如果依据原文，文章中提到了“枪”的使用，所以A不是答案。在第5段中说“雪地管理员”必须身体素质好，所以暗示答案是C。
