2、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, ａｎｄ　the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds ａｎｄ　storm surges(风暴潮). The storm surges ａｎｄ　heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, ｏｒthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia ａｎｄ　in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding ａｎｄ　huge waves crashing on to the shore. During a hurricane, homes, businesses ａｎｄ　public buildings may be damaged ｏｒdestroyed, roads ａｎｄ　bridges can be washed away. A powerful hurricane can kill more people ａｎｄ　destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives ａｎｄ　not be able to get to a safe harbｏｒif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm ａｎｄ　find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane ａｎｄ　go to a safer place near the center of your home. Cover yourself with a blanket ａｎｄ　be sure to keep away from windows ａｎｄ　glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.A powerful hurricane may become the most destructive ______.【单选题】

A.different labels

B.window ａｎｄ　glass doors

C.inlａｎｄ　flooding

D.early warning

E.natural disaster

F.a constant speed

正确答案:E

答案解析:本题有一定难度，需要认真寻找答案依据，答案依据在文章第三段的倒数第二句：A powerful hurricane can kill more people ａｎｄ　destroy more property than any other natural disaster。回来看选项，E项符合原文句意，是答案。

3、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 are citizen scientists asked to do?【单选题】

A.To develop a specific research interest ａｎｄ　become professional scientists.

B.To send their research observations to a professional ｄａｔａｂａｓｅ.

C.To increase their knowledge about climate change.

D.To keep a record of their research observations.

正确答案:B

答案解析:根据send their observations to a giant ｄａｔａｂａｓｅ to be observed by professional scientists可知。

4、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.As a measure of memory, relearning is more sensitive than ______.【单选题】

A.short - term memory

B.relearning

C.needed

D.coded

E.recognition

F.slow forgetting rate

正确答案:E

答案解析:本题难度不大，答案依据比较明显，在文章第四段倒数第二句：Relearning is generally a more sensitive measure of memory than is recognition because…谈到作为测试记忆力的方法来说，再学习比识别更灵敏，回来看选项，E项recognition符合原文句意，是答案。

5、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 San Francisco area is located above several active fault lines.【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。答案依据在第一段第五句：At least seven active fault lines run through the San Francisco area，至少有七条断层地带穿越旧金山，所以本题正确，答案是A。

6、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 _____ 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】

A.closes

B.breaks

C.increases

D.burns

正确答案:B

答案解析:本题有一定难度，关键在理解好文章上下文意义，文章此处要表达的是“断开”的意思，答案是B。

7、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。

8、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second ______ six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.any

B.each

C.some

D.every

正确答案:D

答案解析:本题有一定难度，考查不定代词every的用法，干扰项有一定的干扰。根据上下文逻辑，文章此处是说“……每六百万年仅差一秒”，each后面不能跟复数名词，因此最佳答案是D。

9、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.

A.nothing

B.anyone

C.someone

D.everything

正确答案:D

答案解析:本题难度不大，考查不定代词everything的用法，本题可以先看选项，得到信息提示，很明显，答案是D。

10、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 ______ 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.upon

B.back

C.without

D.with

正确答案:B

答案解析:根据上下文的理解，应该选择back：手机拥有者拿回了手机，再使用一个星期。
