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

A.Alarms

B.Alarm

C.The alarm

D.The alarms

正确答案:D

答案解析:我们知道该空的名词应出现在前文，上一句就提到“Sound Alert，is installing the alarms in a residential home…”，所以这里所要填的词也应该是the alarms。

2、How to Be a Successful BusinesspersonHave you ever wondered why some people are successful in business ａｎｄ　others are not? Here\'s a story about one successful businessperson. He started out washing dishes ａｎｄ　today he owns 168 restaurants.Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, ａｎｄ　when he was 16 years old, he learned to fly a small plane.At the age of 23 ａｎｄ　with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working fｏｒa company that rented cars.While Mr. Kazi was working at the car rental(租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. Fｏｒtwo months, he worked as a cook\'s assistant. His job was to clean the kitchen ａｎｄ　help the cook. "I didn\'t like it," Mr. Kazi says, "but I always did the best I could."One day, Mr. Kazi\'s two co - workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.A few months later, the owners needed a manager fｏｒa new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager ａｎｄ　soon the restaurant was making a profit.A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside ａｎｄ　the food was terrible. Mr. Kazi borrowed money from a bank ａｎｄ　bought the restaurant. Fｏｒthe first six months, Mr. Kazi worked in the restaurant from 8 a. m. to 10 p. m. , seven days a week. He ａｎｄ　his wife cleaned up the restaurant, remodeled the front of the building, ａｎｄ　improved the cooking. They also tried hard to please the customers. If someone had to wait more than ten minutes fｏｒtheir food, Mrs. Kazi gave them a free soda. Before long the restaurant was making a profit.A year later, Mr. Kazi sold his restaurant fｏｒa profit. With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, ａｎｄ　retrained the employees. Before long these restaurants were making a profit, too.Today Mr. Kazi owns 168 restaurants, but he isn\'t planning to stop there. He\'s looking fｏｒmore poorly managed restaurants to buy. "I love it when I go to buy a restaurant ａｎｄ　find it\'s a mess," Mr. Kazi says. "The only way it can go is up. "In the last paragraph, "it\'s a mess" means ______. 【单选题】

A.it\'s small

B.it\'s dirty

C.it\'s profitable

D.it\'s cheap

正确答案:B

答案解析:本题是词义题，难度不大，也是送分题，阅读理解题中的词汇题大多可以通过直接翻查同义词词典直接确定答案。可以确定，mess指“脏乱”，所以答案是B。

3、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 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 _____ work to do before the colｏｒ- changing molecules can be used outside the lab.【单选题】

A.a pair of

B.a type of

C.a lot of

D.a part of

正确答案:C

答案解析:本题难度不大，考查词义辨析。文章此处是说“Sottos和同事们还有很多工作要做”，答案是C。

4、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, ａｎｄ　coordination between hands ａｎｄ　the brain. Many human drivers have all. these ａｎｄ　can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" ａｎｄ　"feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road ａｎｄ　conditions ahead of it. They watch the traffic to the car\'s left ａｎｄ　right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it ａｎｄ　analyzes their positions. Basing on this information, it chooses the right line fｏｒthe intelligent cars, ａｎｄ　gives instructions to the "hands" ａｎｄ　"feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. ______, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time ａｎｄ　in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】

A.So

B.However

C.Besides

D.Therefore

正确答案:C

答案解析:因为前一句已经是however引导的表示“转折关系”的句子，因此不可能接着又出现however引导的另一转折句，所以首先排除B。空白位于句首，而且有一个逗号与句子其他部分隔开，因此空白处应该出现逻辑副词。选项A和D在用做逻辑副词的用法和词义上接近，相互排除，因此答案为C。从空白所在句子的句意上看，该句引出另一信息，因此从句意上判断也需要besides引出表示递进关系的句子。

5、Medicine Award Kicks off Nobel Prize AnnouncementsTwo scientists who have won praise fｏｒresearch into the growth of cancer cells could be candidates fｏｒthe Nobel Prize in medicine when the 2008 winners are presented on Monday, kicking off six days of Nobel announcements. Australian-born U. S. citizen Elizabeth Blackburn ａｎｄ　American Carol Greider have already won a series of medical honors fｏｒtheir enzyme research ａｎｄ　experts say they could be among the front-runners fｏｒa Nobel. Only seven women have won the medicine prize since the first Nobel Prizes were handed out in 1901. The last female winner was U. S. researcher Linda Buck in 2004, who shared the prize with Richard Axel. Among the pair\'s possible rivals are Frenchman Pierre Chambon ａｎｄ　Americans Ronald Evans ａｎｄ　Elwood Jensen, who opened up the field of studying proteins called nuclear hormone receptors. As usual, the award committee is giving no hints about who is in the running before presenting its decision in a news conference at Stockholm\'s Karolinska Institute. Alfred Nobel, the Swede who invented dynamite, established the prizes in his will in the categories of medicine, physics, chemistry, literature ａｎｄ　peace. The economics prize is technically not a Nobel but a 1968 creation of Sweden\'s central bank. Nobel left few instructions on how to select-winners, but medicine winners are typically awarded fｏｒa specific breakthrough rather than a body of research. Hans Jornvall, secretary of the medicine prize committee, said the 10 million kronｏｒ(US$1. 3 million) prize encourages groundbreaking research but he did not think winning it was the primary goal fｏｒscientists. "Individual researchers probably don\'t look at themselves as potential Nobel Prize winners when they\'re at work," Jornvall told The Associated Press. "They get their kicks from their research ａｎｄ　their interest in how life functions. "In 2006, Blackburn, of the University of California, "San Francisco, ａｎｄ　Greider, of Johns Hopkins University in Baltimore, shared the Lasker prize fｏｒbasic medical research with Jack Szostak of Harvard Medical School. Their work ｓｅｔthe stage fｏｒresearch suggesting that cancer cells use telomerase to sustain their uncontrolled growthThe research by Blackburn ａｎｄ　Greider helps suggest the role of____. 【单选题】

A.money in medical research.

B.proteins in cancer treatment.

C.hormones in the functioning of life.

D.telomerase in the growth of cancer cells.

正确答案:D

答案解析:短文的最后一句话表明，研究显示癌细胞利用端粒酶来支持其无限增殖，而这几位科学家的工作为这种研究打下了基础。
