1、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. ______ 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. 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】

答案解析:四个选项中只有B是正确选择，连接了其前后两个句子，使其形成因果关系：她思考微量DNA是否会停留在手机上，所以，她与同事们一起对10名志愿者的翻盖手机进行了分析研究。A、C、D都是转折的意义关系。

2、DietPersons who are overweight should watch their diet carefully in ｏｒｃｅｒto lose pounds. The best way to do this is to start a weight control program. At first it is wise to talk with your doctor. He can advise you of the number of calories you should have in your meals each day. He can tell you about exercising while on your diet. A good rule is to lose slowly. A loss ofa pound ｏｒtwo is plenty. Plan meals around foods you know. This means that it is wise to include foods that you are used to ａｎｄ　that are part of your regular eating habits. When you have lost the weight you wish, simple items can be added to your diet so that you can maintain the weight you want. While you are dieting, try to build a pattern of eating that you can follow later to maintain your desired weight. When dieting, choose low-calorie foods. Avoid such items as fats, fried food, sweets, cakes, cream ａｎｄ　soft drinks. Try to take coffee ａｎｄ　tea without sugar ｏｒcream. Snacks can be part of your diet. Fｏｒexample, a piece of fruit ｏｒa simple dessert saved from mealtime can be eaten between meals. Keep busy! This way you will not be tempted to go off the diet. Make full use of opportunities to exercise. Try walking instead of riding whenever possible. Happy dieting !According to the passage, which of the following statements is NOT true?【单选题】

A.While dieting, you should ask the doctｏｒso that you can lose your weight quickly.

B.Plan meals means to have some foods you like ａｎｄ　take them as your daily eating habits.

C.When you have lost your weight, you can have some coffee ａｎｄ　tea without sugar ｏｒcream.

D.As you are dieting, don\'t forget exercise.

正确答案:A

答案解析:第1段末尾，作者建议“A good rule is to lose slowly A loss ofa pound ｏｒtwo is plenty”，应该慢慢地减肥，选项A（医生会建议你迅速减肥）是错误的。

3、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 3 ______【单选题】

A.Where do hurricanes usually happen?

B.What damages can a hurricane cause?

C.What should you do during a hurricane?

5、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 ______. 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 a lot of work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

A.color

B.trouble

C.what

D.where

正确答案:A

答案解析:前文一直提示分子变红色，所以在此情景下，选颜色是符合全文主题的。

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.Scientists will be able to predict the exact time of an earthquake soon.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题难度较大，没有明显的答案依据，需要通读全文，做出判断。第五段第一句：Looking ahead, scientists are trying to predict when the next majｏｒquake will occur.{炎到展望未来，科学家正努力预测下次大地震的发生，但全文只谈到在积极预测地震，没有提及是否能够预测出准确的时间，所以本题未提及，答案是C。

7、The GuitarThe Museum of Fine Arts in the eastern city of Boston recently began showing a collection of guitars. The exhibit is called Dangerous Curves: The Art of the Guitar. It shows how the instrument developed during the past four centuries. Probably no other musical instrument is as popular around the world as the guitar. Musicians use the guitar fｏｒalmost every kind of music. Country ａｎｄ　western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. ａｎｄ　rock ａｎｄ　roll music would almost be impossible without this instrument. Music experts do not agree about where the guitar first was played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than a thousａｎｄ　years ago. Some other experts say that the ancestｏｒof the modern guitar was brought to Spain from Persia sometime in the twelfth century. The guitar continued to develop in Spain. In the seventeen-hundred it became similar to the instrument we know today. Many famous musicians played the instrument. The famous Italian violinist Niccolo Paganinni played ａｎｄ　wrote music fｏｒthe guitar in the early eighteen hundred. Franz Schubert used the guitar to write some ofhis famous works. One guitar in the Boston Fine Arts display was played by Les Paul. It is a very old electric guitar. Mister Parl began experimenting with ways to make an electric guitar in the nineteen-thirties. The Gibson Guitar Company began producing its famous Les Parl Guitar in 1952. The instrument has the same shape ａｎｄ　the same six strings as the traditional guitar, but it sounds very different. The guitar has always been important to blues music. The electric guitar Mister Paul helped develop made modern blues music possible. There have been many great blues guitarists. Yet, music experts say all blues guitar players are measured against one man ａｎｄ　his famous guitar. That man is B-B King. Every blues fan knows that years ago B-B King named his guitar Lucille. Lucille is so important to American music that the Smithsonian Institution in Washington D-C has asked fｏｒit. They want to display the large, beautiful black guitar in one of the museums because it is a part ofAmerican culture. John Denvｏｒis one of the specialists in playing the guitar. 【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:C

答案解析:本题说的是约翰丹佛，吉他演奏专家之一。文章提到了B-B King，但没有提及约翰丹佛，尽管我们知道他确实是吉他演奏专家。

8、Inventｏｒof LEDWhen Nick Holonyak ｓｅｔout to create a new kind of visible lighting using semiconductｏｒalloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, ｏｒLEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights ａｎｄ　other everyday technology. On April 23,2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the lOth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. "Anytime you get an award big ｏｒlittle. It\'s always a surprise. " Holonyrak said. Holonyak, 75, was a student of john Bardeen, an inventｏｒof the transistor, in the early 1950s. After graduate school, Holonyak worked at Ben Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches. Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, ａｎｄ　are more environmentally friendly ａｎｄ　effective. Holonyak, now a professｏｒof electrical ａｎｄ　computer engineering ａｎｄ　physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn\'t realize how many uses they would have. "You don\'t know in the beginning. You think you\'re doing something important. You think it\'s worth doing, but you really can\'t tell what the big payoff is going to be, ａｎｄ　when, ａｎｄ　how. You just don\'t know, "he said. The Lemelson. MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award fｏｒher work on a new generation of "molecular sieves", that can separate molecules by size. Holonyak was the inventｏｒof the transistｏｒin the early 1950s.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:答案相关句：Holonyak, 75，was a student of John Bardeen，an inventｏｒofthe transistor，in the early 1950s（该句所反映的内容是：John Bardeen是20世纪50年代初期晶体管的发明者），问题句的内容与原文的内容不一致，因此选B。

9、HalloweenHalloween is an autumn holiday that Americans celebrate every year. It means "holy evening", ａｎｄ　it comes every October 31, the evening before All-Saints Day. It used to be thought the most wonderful night of the year. It was the night when witches ａｎｄ　evil spirits came back on earth. People kept up many strange old customs in an effort to keep these evil things away. Farmers used to light big fires in their fields, ａｎｄ　the farm workers ａｎｄ　their families would walk around the fields singing old songs. Sometimes they would stop to hear the local priest offer prayers to the good spirits, ａｎｄ　ask them to help keep the evil ones away. Great care was taken that none of the farm animals were left in the fields. They would all be locked up safely in their stables, ａｎｄ　over each of the stable doors a few rowan leaves would be hung. Witches ａｎｄ　evil spirits would not go anywhere near the rowan tree. In more recent times, Halloween has become a time fｏｒthe parties, when children dress up as witches ａｎｄ　play all kinds of special games. After the games there is often a big supper with plenty of pumpkin pie, cakes ａｎｄ　a lot of other delicious things to eat. But fｏｒthe most part the children enjoy the fun of dressing up ａｎｄ　playing their favorite game of "Trick ｏｒTreat". They run down each street knocking on the doors crying loudly "Trick ｏｒTreat! Money ｏｒeat!", ａｎｄ　most people have some sweets ｏｒmoney ready to give them. Those that do not can expect maybe to have a tyre flattened, ｏｒtheir windows covered in soap. ｏｒthe children may just knock on the doｏｒａｎｄ　run away. Some children think of other people on Halloween. They carry boxes fｏｒUNICEF (The United Nations International Children\'s Emergency Fund). They ask fｏｒmoney to help poｏｒchildren all around the world. Of course, every time they help UNICEF, they usually receive a treat fｏｒthemselves, too. Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins ａｎｄ　put lights inside. It looks like there is a person looking out of the pumpkin! These lights are called jack-o\'-lanterns, which means "Jack of the lantern". But in this modern age many of the pumpkins are being replaced with plastic electric ones that can be brought out each year. Why did Halloween use to be thought the most wonderful night of the year?【单选题】

A.Because people thought at that night witches ａｎｄ　evil spirits came back on earth.

B.Because it was the time fｏｒparties.

C.Because it was an autumn holiday that Americans celebrated every year.

D.Because farmers were allowed to light big fires ａｎｄ　sing songs at that night.
