　　Ⅳ.阅读理解

　　A

　　Scientists in the United States have developed a computer program that they say could provide an early warning of major earthquakes. The new system is designed to give warnings seconds before an earthquake strikes.

　　That may not sound like very long. However, it could give people time to get under a table or take shelter someplace safe.The flow of electric power or gas could be cut off. Air traffic controllers could warn away pilots.Even so­called“smart buildings”could be designed to get ready.

　　The system uses a mathematical program to measure information collected by instruments deployed across the Los Angeles area. Southern California has more than 150 seismic(地震的)stations that measure movements within the ground.The information they collect is sent to a high­speed computer.

　　An earthquake shakes the ground with two kinds of waves. The new system uses information from a low­energy wave that moves quickly but causes little damage. Experts call this the P­wave.The slower but stronger S­wave is the main threat to life and property. Japan has a system based on P­waves. There，the warnings are used to slow down high­speed bullet trains.Other countries have warning systems that measure S­waves.

　　The new system is designed to estimate the strength of the earthquake once the shaking starts. Areas directly above the center of the earthquake would have the least warning. Distant places might have as long as forty seconds.

　　The scientists are still testing their proposed system in the Los Angeles area. Professor Allen notes that an early warning system for earthquakes would require a major campaign of public education.

　　【解题导语】 美国的科学家开发了一种新的计算机程序，该程序可在大型地震来临前提供预警。

　　1．Which of the following is TRUE about the new earthquake warning system?

　　A．It can give people enough time to run away from earthquakes.

　　B．It can give people seconds to take immediate measures.

　　C．It is developed in Japan.

　　D．It is a system based on S­waves.

　　答案　B　[细节理解题。由第一段最后一句可知选B。]

　　2．Which of the following can benefit from the new system most?

　　A．Areas far away from the center of the earthquake.

　　B．Areas directly above the center of the earthquake.

　　C．The Los Angeles area.

　　D．High­speed bullet trains.

　　答案　A　[推理判断题。由倒数第二段第二句知，距离震中越近的地区would have the least warning，故离震中愈远，受益愈大。]

　　3．From what Professor Allen notes in the last paragraph we can infer that________.

　　A．it's very important for people to become educated

　　B．it's very important to warn people before an earthquake starts

　　C．it's very important for people to know about earthquakes

　　D．it's very important for people to know about the new system

　　答案　D　[由全文最后一句可知选D。]

　　4．What do we learn from the passage?

　　A．People could cut off electric power or gas immediately after the new system gives a warning.

　　B．A low­energy wave may move slowly and cause little damage.

　　C．Japan has a warning system based on S­waves to slow down bullet trains.

　　D．The new system has been employed in warning of major earthquakes all over the United States.

　　答案　A　[细节理解题。答案见文中第二段第三句。]

　　B

　　A maths talent who won fame this week for giving up a million­dollar prize is living with his mother in a simple flat in St Petersburg，co­existing on her￡30­a­month pension，because he has been unemployed for many years.

　　The Sunday Telegraph tracked down the strange recluse (隐士)who shocked the maths world when he solved a century­old puzzle known as the Poincare Conjecture.

　　Grigory Perelman's trouble comes from a split with a leading Russian mathematical institute, the Steklov, in 2003.When the Institute in St Petersburg failed to re­elect him as a member，Dr Perelman was left feeling an“absolutely ungifted and untalented person”，said a friend.He became unconfident and cut himself off.

　　Other friends say he cannot afford to travel to the International Mathematical Union's congress in Madrid，where many people want him to receive the maths equivalent(等价物)of the Nobel Prize，and that he is too modest to ask anyone to pay for his trip.

　　Interviewed in St Petersburg，Dr Perelman insisted that he was unworthy of all the attention, and was uninterested in the prize.“I do not think anything that I say can be of the slightest public interest，”he said.“I am not saying that because I value my privacy，or that I am doing anything I want to hide.There are no top­secret projects going on here.I just believe the public has no interest in me.”

　　He continued：“I know that self­promotion happens a lot and if people want to do that，good luck to them，but I do not regard it as a positive thing. I realised this a long time ago and nobody is going to change my mind.Newspapers should be more discerning(有洞察力的)over who they write about. They should have more taste.As far as I am concerned，I can't offer anything for their readers.”

　　Dr Perelman has some small savings from his time as a lecturer，but is apparently unwilling to increase them with the $1 million offered by the Clay Mathematics Institute in Cambridge，Massachusetts，for solving one of the world's seven “Millennium Problems.”

　　【解题导语】 数学天才Perelman博士因没有被选进俄罗斯数学研究所和母亲隐居在圣彼得堡，虽然他由于解决数学界世纪难题而震撼了数学界，却放弃了一百万美元的奖励金，Perelman坚持说自己不值得媒体和公众的关注。

　　5．Grigory Perelman lives with his mother because________.

　　A．he has to look after her

　　B．his mother has a million dollars

　　C．he has been out of work for a long time

　　D．he is badly paid at the mathematical institute

　　答案　C　[细节理解题。第一段介绍Grigory Perelman生活状况及原因，他和母亲住在圣彼得堡一所简陋的房里和母亲一起靠她一个月30英镑的退休 金过日子，因为他已多年没有工作。由此看出本题C项正确。]

　　6．The phrase“absolutely ungifted and untalented person”shows that Dr Perelman felt________.

　　A．angry

　　B．discouraged

　　C．proud

　　D．confident

　　答案　B　[语义理解题。第三段解释Perelman生活艰苦的原因：由于圣彼得堡的数学研究所没有选中他，据他朋友说，他就感觉自己是一个绝对没有天赋不聪明的人。从那时起他便不再有自信、与世隔绝，由此看出Perelman感觉没有信心，失望。]

　　7．Grigory Perelman refused to accept the prize because______.

　　A．he thought the prize was worthless

　　B．he didnt't believe the news

　　C．he couldn't afford to travel to Madrid

　　D．he showed no interest in it

　　答案　D　[细节理解题。第四段说明Dr Perelman放弃奖金的原因。第一句“在圣彼得堡家中接受采访时Dr Perelman坚持说他不值得关注，并且对奖金不感兴趣。”所以本题D项正确。]

　　8．From the passage, we can infer that Grigory Perelman

　　________.

　　A．solved the most difficult maths problem

　　B．has a strong personality

　　C．wanted to make himself known to all

　　D．didn't get on well with the press

　　答案　B　[归纳推理题。短文第一段介绍Perelman尽管生活困难，但他放弃了一百万美元的奖金，第五、六段写他尽管解决了数学界的世纪难题，但他不想成为人们关注的焦点，不想引起人们对他的注意。所以本题B项正确。]
