1、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!Paragraph 3 ______【单选题】

A.Cell phones ａｎｄ　the family

B.Commercial cell phone systems

C.Cell phones in everyday life

D.Cell phones fｏｒteenagers

E.History of cell phones

F.Problems with cell phones

正确答案:C

答案解析:本题难度不大，主旨句比较明显，就是第二段的第一句：手机在我们日常生活中非常普遍。后面是对其的具体阐述，介绍了手机在日常生活里发挥的作用。C项Cell phones in everyday life是本段主旨句的同义解释，是答案。

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 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 ______ work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

A.a part of

B.a type of

C.a lot of

D.a part of

正确答案:C

答案解析:意思应该是在变色分子可用于实践之前，Sottos和她的团队还需要做很多的努力。所以选a lot of合适。

3、Dung to DeathFields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food ａｎｄ　water, helping to create a new generation of antibiotic-resistant "superbugs". The warning comes from a researcher in Switzerlａｎｄ　who looked at levels of the drugs in farm slurry His findings are particularly shocking because Switzerlａｎｄ　is one of the few countries to have banned antibiotics as growth promoters in animal dead.Some 20,000 tons of antibiotics are used in the European ｕｎｉｏｎａｎｄ　the US each year. More than half are given to farm-animals to prevent disease ａｎｄ　promote growth. But recent research has found a direct link between the increased use of these farmyard drugs ａｎｄ　the appearance of antibiotic-resistant bugs that infect people. Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end. up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute fｏｒEnvironmental Science ａｎｄ　Technology in Dubendorf. ａｎｄ　manure contains especiaily high levels of bugs that are resistant to antibiotics he says.With millions of tons of animals manure spread onto fields of crops such as wheat ａｎｄ　barley each year, this pathway seems an equally likely route fｏｒspreading resistance, he said. The drugs contaminate the crops, which are then eaten. ______Mueller is particularly concerned about aｇｒｏｕｐof antibiotics called sulphonamides. They do not easily degrade ｏｒdissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously. There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged ａｎｄ　are not broken down by conventional sewage treatment.【单选题】

A.They do not easily degrade ｏｒdissolve in water.

B.ａｎｄ　manure contains especiaily high levels of bugs that are resistant to antibiotics he says.

C.Animal antibiotics is still an area to which insufficient attention has been paid

D.But recent research has found a direct link between the increased use of these farmyard drugs ａｎｄ　the appearance of antibiotic-resistant bugs that infect people.

E.His findings are particularly shocking because Switzerlａｎｄ　is one of the few countries to have banned antibiotics as growth promoters in animal dead.

F.They could also be leaching into tap water pumped from rocks beneath fertilized fields.

正确答案:F

答案解析:选项F中的also 一词说明前面应讲到过一个类似的内容。这句讲的是这些药物可能从施过肥料的农田下面的岩石沥滤到自来水里去；前面一句讲的是受到这些药物污染的谷物被人食用，这两句讲的都是这些药物如何对人类造成威胁。

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. The designers of the VLT are surprised at____. 【单选题】

A.its detecting power

B.millions of light years away in space

C.the location of the VLT

D.as an example

E.the birth of the earth

F.the rotation of the earth

正确答案:A

答案解析:文章第2段最后一句也概括提到了这句话的意思。

5、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.Paragraph 2 ______【单选题】

A.Where do hurricanes usually happen?

B.What damages can a hurricane cause?

C.What should you do during a hurricane?

D.What is a hurricane?

E.What are different names of hurricanes?

F.How do you know a hurricane is coming?

正确答案:E

答案解析:本题有一定难度，需要吃透文章句意，段落主旨句比较明显，在文章第二段的第一句：Hurricanes are given a different label，depending on where they occur.回来看选项，E项简单概括了第一段的主要意思，是答案。

6、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

正确答案:D

答案解析:本题难度不大，到文章里定好位，考生会很快确定答案依据。找到文章第六段，最后一段开头谈到，两个小伙都说有机会赚钱是让人兴奋。回来看选项，D项是近义解释，是答案。做本题时也可以先看选项，得到信息提示。

7、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.The half - life of C - 14 is about 25 ,000 years.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题有较大难度，答案依据不明显，需要通读全文作出判断。通读全文后可以发现文章并未提及碳的半衰期是25，000年，所以本题是未提及的，答案是C。

8、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 ______ 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 ｏｒdown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】

A.basison

B.baseon

C.basingon

D.basedon

正确答案:D

答案解析:Alarms是主语，have already been installed是谓语，所以要填的动词应该是分词形式做定语，所以4个答案只有D可能。be based on:以……为基础。

9、Human facial expressions differ from those of animals in the degree to which they can be deliberately controlled ａｎｄ　modified. 【单选题】

B.noticeably

C.intentionally

D.absolutely

正确答案:C

答案解析:deliberately和intentionally同义：有意地、故意地；sufficiently：充分地、足够地；noticeably：显而易见地、明显地；absolutely：绝对地、完全地。

10、Some Unusual CelebrationsSome holidays are well - known all around the world. Among them are New Year\'s Eve celebrations. Also common are days in honｏｒof love ａｎｄ　friendship, like Valentine\'s Day. Each country has its own special holidays too, often to mark important events in its history. Schools, banks ａｎｄ　government offices all close on days like these. _____ A few of them are really very strange.Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool\'s Day, fｏｒexample. No one knows when ｏｒwhy it began. Today it is celebrated in many countries—France, Englａｎｄ　ａｎｄ　Australia, among others. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you?Dyngus Day in Polａｎｄ　seems strange too. On this day, it is traditional fｏｒboys to pour water over the heads of girls. Here is the strangest part, they do it to girls they like.Other unusual celebrations take place in a single city ｏｒtown. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. Then begins the world-s biggest food fight. Fｏｒtwo hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains ａｎｄ　catch a wild goat. They bring him back to town, put a crown on his head, ａｎｄ　make him king fｏｒthree days.There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea fｏｒa new holiday ａｎｄ　tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 29. That is supposed to be Toothache Day.Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.【单选题】

A.They bring him back to town, put a crown on his head, ａｎｄ　make him king fｏｒthree days.

B.Some of the days people celebrate, however, are less serious.

C.That is supposed to be Toothache Day.

D.Then begins the world-s biggest food fight.

E.Some people have fun imagining new holidays.

F.Jokes are supposed to be funny, but these jokes do not make everyone laugh.
