1、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 have been keeping records of lake temperatures fｏｒover 30 years.【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，在文章第二段第二句：Between 1985 ａｎｄ　2009，satellites recorded the nighttime temperatures of the surfaces of 1671 akes.很明显，是24年，而不是30多年，题干和原文句意不符，答案是B。

2、Easy ListeningStudents should be jealous. Not only do babies get to doze their days away, but they\'ve also mastered the fine art of learning in their sleep. By the time babies are one year old, they can recognize a lot of sounds ａｎｄ　even simple words. Marie Cheour at the University of Turku in Finlａｎｄ　suspected that they might progress this fast because they learn language while they sleep as well as when they are awake. To test the theory, Cheour ａｎｄ　their colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel sounds one that sounds like "oo"; another like "ee" ａｎｄ　the third boundary vowel peculiar to Finnish ａｎｄ　similar languages that sounds like something in between. EEG (脑电图) recording of the infants brains before ａｎｄ　after the session showed that the newborns could not distinguish the sounds. Fifteen of the babies then went back with their mothers, where the rest were split into two sleep-study groups. Oneｇｒｏｕｐwas exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to the other, easier-to-distinguish vowel sounds. When tested in the morning, ａｎｄ　again in the evening, the babies who\'d heard the tricky boundary vowels all night showed brainwave activity indicating that they could now recognize this sound. They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all. Cheour doesn\'t know how babies accomplish this nighttime learning, but she suspects that the special ability might indicate that unlike adults, babies don\'t "turn off" their cerebral cortex (大脑皮层) while they sleep: The skill probably fades in the course of the first years of life, she adds so forget the idea that you can pick up the tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders. Finnish vowels are easy to distinguish. 【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:C

答案解析:第4段最后一句是“while the others listened to the other, easier-to-distinguish vowel sounds”，其他的较容易区分的元音是指“oo”和“ee”这两个音。这两个音容易区分并不等于所有的元音都容易区分。

3、Sharing SilenceDeaf teenagers Orlando Chavez ａｎｄ　German Resendiz have been friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak ａｎｄ　hear.Orlando lost his hearing at the age of one. German was born deaf, ａｎｄ　his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kinder garten."We were in a special class with about 25 other deaf kids," German remembered. "Before then, I didn\'t know I was deaf ａｎｄ　I was different.""Being young ａｎｄ　deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understａｎｄ　us ａｎｄ　we didn\'t understａｎｄ　them. But we\'ve all grown up together, ａｎｄ　today, I\'m popular because I\'m deaf. Kids try to communicate with me."Some things are very difficult fｏｒthe two boys. "We can\'t talk on the phone, so if we need help, we can\'t call an emergency service," German signs. "ａｎｄ　we can\'t ｏｒｃｅｒfood in a drive - thru."Despite of their difficulties, the two boys have found work putting food in bags at a local supermarket.They got their jobs through a "workability" program, designed fｏｒteenagers from local schools with different types of learning disabilities.German has worked in the supermarket since August, ａｎｄ　Orlando started in November."The other people who work here nave been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we\'ve learned a lot ａｎｄ　we\'re getting better."The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute fｏｒthe Deaf in New York.The word "emergency" in paragraph 5 is closest in meaning to ______.【单选题】

A.food

B.alarm

C.crisis

D.quick

正确答案:C

答案解析:本题难度不大，干扰项干扰不强，考生会很快确定答案。emergency指“紧急”，和crisis“危机，紧急关头”是近义词。B项alarm指“警戒”，最佳答案是C。

4、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope ａｎｄ　is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) ａｎｄ　it will destroy itself in a few million years\' time. It is five times brighter than the sun ａｎｄ　when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that ｓｅｔout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, ａｎｄ　astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, ａｎｄ　we will have a much clearer picture of how our planet was born. Paragraph 3____【单选题】

A.Events That Took place Before the Earth Existed

B.Power of the Telescope

C.Details of Eta Carinae

D.Invention of a Time Machine

E.Biggest Telescope

F.Ultraviolet Laser Rays

正确答案:C

答案解析:文章第3段介绍了Eta Carinae的情况，故C为正确答案。

5、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 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. ______, 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.Generally

B.Surprisingly

C.Disappointedly

D.Shortly

正确答案:B

答案解析:最后一段的第一和第二句告诉我们手机经过清洗后仍然有微量DNA出现。所以这里要用surprising这个副词，表示令人惊讶。

6、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.When a hurricane arrives, fishermen are in great danger if they are at sea ａｎｄ　do not get ______.【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:D

答案解析:本题有一定难度，需要吃透文章句意，答案依据在文章第三段的倒数第一句：Fisherman are at special risk---they may be at sea－－ if they do not receive adequate warning.回来看选项，D项和原文句意相近，是答案。

7、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。

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 _____ 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 every 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.by

B.away

C.along

D.with

正确答案:B

答案解析:本题难度较大，考查词义辨析，干扰项干扰较大。根据上下文逻辑，文章此处是说“当我们飞离太阳时温度会变得更低”，答案是B。

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

A.until

B.although

C.after

D.before

正确答案:D

答案解析:本题有一定难度，干扰项干扰较大，考查介词before的用法，文章此处是说，“它在建筑物倒塌之前会变成红色”，此处要用“之前”的意思，答案是D。

10、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 1 ______【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:E

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。通读文章第一段可以发现，第一段主要对记忆力下了定义，围绕定义展开了阐述，回来看选项，E项What is memory?简单概括了第一段，是答案。
