1、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building ａｎｄ　that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home fｏｒblind people in Sommerｓｅｔａｎｄ　a resource centre fｏｒthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the doｏｒwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the source of a wide bａｎｄ　of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising ｏｒfalling frequencies to indicate whether people should go up ______ down stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】

A.or

B.and

C.but

D.otherwise

正确答案:A

答案解析:根据前半句的rising ｏｒfalling frequencies,可以看出这句话也应该填连接词or，表示或者。

2、Cell Phones1. Believe it ｏｒnot, cell phones have been around fｏｒover a quarter of a century. The first commercial cell phone system was developed by the Japanese in 1979, but cell phones have changed a lot since that time. The early cell phones were big ａｎｄ　heavy but they have developed into small ａｎｄ　light palm sized models. There are huge developments in their functions, too. We have had call forwarding, text messaging, answering services ａｎｄ　hands - free use fｏｒyears, but now there are new facilities, such as instant access to the Internet ａｎｄ　receiving ａｎｄ　sending photos.2. Cell phones have become very common in our lives. Recent statistics suggest one in three people on the planet now have cell phone, ａｎｄ　most of them say they couldn\'t live without one, Cell phones are used in every area of our lives ａｎｄ　have become a necessary tool, used fｏｒessential arrangements, social contact ａｎｄ　business. It easier to call fｏｒhelp on the highway. It possible to keep in touch with people "on the move" when people are traveling.3. Cell phones have made communication easier ａｎｄ　have reduced the need fｏｒfamily arguments f We can use cell phones to let our family know we\'ll be late ｏｒif there\'s a sudden change of plan ｏｒan emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late. They can now contact their children at any time.4. This does not mean that cell phones are all good news. Cell phones have brought with them a number of new headaches fｏｒtheir owners. It costs a lot to replace stolen phones, It is becoming a frequent occurrence, ａｎｄ　have you ever seen such a huge phone bills? More serious, however, Cell phones bring the potential health problem. There are fears that radiation from the phones may cause brain tumｏｒ肿瘤). This may be a time bomb waiting to happen to younger people who have grown up with cell phones. They simply can\'t live without cell phones!Cell phones are common in our lives ａｎｄ　have become ______.【单选题】

A.a necessity

B.an emergency

C.a number of new headaches

D.family arguments

E.big ａｎｄ　light palm - sized models

F.countless new facilities

正确答案:A

答案解析:本题难度不大，虽然答案依据不太明显，但第二段的主旨句可以看做是答案依据，通读第二段，可以判断出手机已成一个必需的工具，所以答案是A。

3、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.How does light pollution affect wildlife? ______【单选题】

A.Animals may go off course.

B.It helps migrating birds find their homes.

C.Animals are afraid to go out after sunset.

D.It helps birds fall asleep.

正确答案:A

答案解析:本题难度不大，答案依据比较明显，在文章第六段第三句，这句话谈到，人造光源会误导动物，造成动物偏离飞行路线，回来看选项，A项符合原文句意，是答案。

4、The SmogFｏｒover a month, Indonesia was in crisis. Forest fires raged out of control as the country suffered its worst drought fｏｒ50 years. Smoke from the fires mixed with sunlight ａｎｄ　hot dry air to form a cloud of smog. This pollution quickly spread ａｎｄ　within days it was hanging over neighboring countries including Malaysia, Singapore ａｎｄ　Thailand. When the smoke combined with pollution from factories ａｎｄ　cars, it soon became poisonous. Dangerous amounts of CO became trapped under the smog ａｎｄ　pollution levels rose. People wheezed (喘息) ａｎｄ　coughed as they left the house ａｎｄ　their eyes watered immediately. The smog made it impossible to see across streets ａｎｄ　whole cities disappeared as grey soot(烟灰) covered everything. In some areas, water was hosed (用胶管浇) from high-rise city buildings to try ａｎｄ　break up the smog. Finally, heavy rains, which came in November. Put out the fires ａｎｄ　clear the air. But the environmental costs ａｎｄ　health problems will remain. Many people from South-Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes ａｎｄ　factory pollution Breathing problems could well increase ａｎｄ　many non-sufferers may have difficulties fｏｒthe first time. Wildlife has suffered too. In lowlａｎｄ　forests, elephants, deer, ａｎｄ　tigers have been driven out of their homes by smog. But smog is not just an Asian problem. In fact. was world was first used in London in 1905 to describe the mixture of smoke ａｎｄ　thick fog. Fog often hung over the capital. Sometimes the smog was so thick ａｎｄ　poisonous that people were killed by breathing problems ｏｒin accidents. About 4, 000 Londoners died within five days as a result of thick smog in 1952. Water was used to try to break up the smog. 【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:题句的意思是“人们用水来驱散烟雾”。第3段第2句就有这层意思，故选A。

5、The town is famous fｏｒits magnificent buildings.【单选题】

6、Storms Sink ShipsRescuers have found the bodies of over 130 people killed in two ferry disasters in Bangladesh. The accidents happened during a storm that hit the country on April 21. Hundreds more are missing ｏｒfeared dead. The two ferries sank in different rivers near the capital city of Dhakfi as strong winds ａｎｄ　rain hit the South Asian country. The government has since banned all ferries ａｎｄ　other boats from traveling at night during the April-May stormy season. One of the ferries, MV Mitali, was carrying far more people than it was supposed to. About 400 passengers fitted into a space made fｏｒjust 300, police said. The second ferry carried about 100 passengers. "The number of deaths is certain to rise." said an official in charge of the rescue work. "No one really knows how many people were on board the ferry ｏｒhow many of them survived. Ferries in Bangladesh don\'t always keep passenger lists, making it difficult to determine the exact number of people on board. Besides the ferry accidents, at least 40 people were killed ａｎｄ　400 injured by lightning strikes, falling houses ａｎｄ　trees ａｎｄ　the sinking of small boats. Storms are common this time of year in Bangladesh, as are boating accidents. Ferry disasters take away hundreds of lives every year in a nation of 130 million people. Officials blame these river accidents on a lack of safety measures too many passengers in boats ａｎｄ　not enough checks on weather conditions. Ferries are a common means of transport in Bangladesh. It is a country covered by about 230 rivers. Some 20,000 ferries use the nation\'s Waterways every year. ａｎｄ　many of them are dangerously overcrowded. Since 1977, more than 3,000 people have died in some 260 boating accidents.How many people have been found dead in the two ferry disasters?【单选题】

A.Over 130.

B.At least 40.

C.About 400.

D.Over 3,000.

正确答案:A

答案解析:第1段第1句说到“救援人员已经找到了在孟加拉国的两次渡船失事中的130多人的尸体”。当然，实际的死亡人数还要高。

7、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.A slight temperature increase in a lake could be harmful fｏｒfish.【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，答案依据比较明显，在文章第三段最后一句：But in a lake, slightly warmer temperatures could mean more algae（才（藻）,ａｎｄ　algae can make the lake poisonous to fish.谈到湖水温度上升会产生很多水藻，给湖里的鱼类带来毒害，题干和原文句意相符，答案是A。

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 ______ 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.that

B.such

C.much

D.more

正确答案:D

答案解析:本题有一定难度，考查词义辨析，干扰项有一定的干扰。根据上下文逻辑，文章此处是说“……使世界原子钟更准确”，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. 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 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 colｏｒ_____. 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.repairs

B.controls

C.finishes

D.disappears

正确答案:D

答案解析:本题有一·定难度，关键在理解好文章上下文意义，文章此处是说“红色消失了”，答案是D。

10、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.Both boys are happy to ______.【单选题】

A.design programs tｏｒthe deaf

B.work at the National Technical Institute fｏｒthe Deaf

C.help students with learning disabilities

D.have the opportunity to earn money
