C
A light emitting diode （发光二极管）, or L．E．D．, is a device that shines when electricity passes through it．But it works differently than traditional kinds of light bulbs．Light emitting diodes use less energy and last much longer than bulbs with a filament （灯丝） inside．L．E． D．’s are also cooler to the touch, and shine a lot brighter than they used to．
Red L．E．D．’s have long been used as signal lights on electronic equipment．But now light emitting diodes also come in blue and other colors．Colored L．E．D．’s are used to show images on everything from wireless phones to huge video signs．And white L．E．D．’s are being used increasingly to replace traditional lighting systems．
But all these require electricity．In poor countries, people often burn fuel to produce light．But the smoke can make people sick．So an electrical engineering professor from Canada started a project to produce L．E． D．lighting systems for the developing world．These lights are powered by batteries that can be recharged with energy from the sun．The batteries can also be charged through other ways, such as wind power and water power．
Professor David Irvine-Halliday tells the story of how he got the idea．In 1997, while climbing in the Annapurna mountains in Nepal, he saw a small school．All the children were outside．He looked through a window and saw that inside the school was dark．The school had a sign that read: "We have no teachers．If you want to stay and teach for a few days, we would be very pleased．" Professor Irvine-Halliday says that experience had a big effect on him．Back at the University of Calgary, he was on the Internet one day．He saw a company in Japan selling bright white L．E． D．’s．So he built a light with some．This is how he began the Light Up the World Foundation．
48．Compared with traditional kinds of light bulbs, L．E．D．’S________．
A．waste a lot of energy B．need shorter time to make
C．shine much brighter D．are warmer to touch
49．According to the passage, we know that L．E．D．’s________．
A．will replace all the lights B．will be more and more popular
C．will be only colored ones D．will be only used in developing countries
50．According to the passage, we can infer that the purpose of the Light Up the World Foundation is to________．
A．develop L．E．D．lighting system for the developing world
B．sell bright white L．E．D．’s
C．collect money for developing countries
D．earn money by selling L．E．D．’s

B
Rome-Doctors and medical groups around the world last weekend reacted with strong opposition to the news that an Italian specialist is on the point of cloning the first human baby．　　
Dr．Severino Antinori, who is the head of a hospital in Rome, has been referred to in an Arab newspaper as claiming that one of his patients is eight weeks pregnant （怀孕的）with a cloned baby．　　
Antinori refused to comment on the reports, but in March 2001 he said he hoped to produce a cloned embryo （卵）for implantation within two years．So far seven different kinds of mammals have already successfully cloned, including sheep, cats and most recently rabbits．　　
Doctors showed their doubt and were strongly opposed although they admit that human cloning would finally come true unless there was a world wide ban on the practice．　　
Professor Rudolf Jaenisch of the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology said: “I find it astonishing that people do this where the result can be foretold that it will not be a normal baby．It is using humans as guinea pigs．It makes people feel sick．” But Ronald Green, director of the Ethics institute at Darmouth College in the US, said it is unlikely that an eight-week-old pregnancy would lead to a birth．　　
So far all cloned animals have suffered from some different serious disorders, many of them dying soon after their births ．　　
Doctors are opposed to human cloning because they are worried about the welfare of the cloned child if there is one．　　
“There are no benefits of cloned human beings, just harm,”said Dr．Michael Wilks of the UK．
45．What is the doctors’ general attitude to cloning of humans according to the passage?
A．They are against it． B．They support it．
C．They welcome it． D．They pay no attention to it．
46．Which of the following statements is true according to the passage?
　 A．Doctor Severino Antinori is strongly opposed to cloning human beings．
　 B．Up to now, seven kinds of animals have been cloned, including sheep, cats, humans and rabbits．
　 C．Professor Rudolf Jaenisch is carrying on an experiment on cloning an eight-week-old embryo．
　 D．Ronald Green doubts about the future successful birth of the so-called cloned embryo．
47．Which is the best title for the passage?
　 A．The Success of Cloning Humans B．The Anger at Cloning Humans
　 C．Failure of Cloning Humans D．First Cloned Human?

第二部分：阅读理解（共两节，满分30分）

Americans spend their free time in various ways．
America is a country of sports — of hunting, fishing and swimming, and of team sports like baseball and football．Millions of Americans watch their favorite sports on television．They also like to play in community orchestras （管弦乐队）, make their own films or recordings, go camping, visit museums，attend lectures, travel, garden, read, and join in hundreds of other activities．The people also enjoy building things for their homes, sewing their own clothes, even making their own photographs．They do these things for fun as well as for economy．
But as much as Americans enjoy their free time, the country is at the same time a “self-improvement” country．More than 25 million adults continue their education, chiefly by going to school in the evening, during their own free time, at their own expense．Added to the time spent on personal activities, Americans a1so devote a great amount of their time to the varied needs of their communities．Many hospitals, schools, libraries, museums, parks, community centers, and organizations that assist the poor depend on the many hours citizens devote to these activities, often without any pay．Why do they do it?
There are several answers．The idea of cooperating and sharing responsibility with one another for the benefit of all is as old as the country itself．
When the country was first founded in 1776, it was necessary for the settlers to work together to live．They had crossed dangerous seas and risked all they had in their struggle for political and religious freedom．There remains among many Americans a distrust of central government．People still prefer to do things themselves within their communities, rather than give the government more control．
Sometimes people offer their time because they wish to accomplish something for which no money is paid, to do something that will be of benefit to the entire community．It is true that some people use their leisure because they are truly interested in the work; or they are learning from the experience．
No matter what the reason is, hundreds of thousands of so-called leisure hours are put into hard, unpaid work on one or another community need．
1．This passage is mainly about ________．
A．why America is a country of sports
B．how Americans spend their free time
C．why America is a “self-improvement” country
D．how Americans are devoted to their community activities
2．The writer mentions the foundation of the country in order to indicate ________．
A．the early history of America
B．the American people’s determination to live
C．the reason for Americans’ willingness to cooperate and share responsibility
D．the American people’ s love for freedom
3．Which of the following best explains the meaning of the underlined word “leisure”?
A．work time B．energy C．effort D．spare time
4．What can we infer from the text?
A．The first settlers left their hometown for political and religious reasons．
B．Many Americans don’t trust the central government．
C．American people enjoy building things for their homes just for fun．
D．Americans continue their education at their own expense．

“I sat-in at a restaurant for six months, and when they finally agreed to serve me, they didn’t have what I wanted”---so went a famous line. In reality, the sit-in movement was not a joke. It began in Greensboro, North Carolina, at 4:30 P. M. , on the afternoon of February 1, 1960. On that day, Ezell Blair Jr. , Joseph McNeil, David Richmond, and Franklin McClain entered an F. W. Woolworth store. They sat down at a segregated（隔离的）lunch counter, ordered coffee, and then refused to leave when told, ‘We don’t serve Negroes. ”
The four young men had expected not to be served. What no one had expected, however, was that they would sit there and politely, but firmly, refuse to leave. This was 1960, and throughout the South black people were not allowed to sit at the same lunch counters with whites, swim at the same beaches, use the same water fountains, or worship at the same churches. Segregation was the law, and it meant separation of the races in every way.
The next day, the four returned to Woolworth’s---this time accompanied by sixteen other students. Again they sat at the lunch counter and requested service. Again they were refused. And again, they declined to leave. On Wednesday, February 3, seventy students filled the Woolworth’s store. This time, the group included white students as well as black. Many brought school books and studied while they waited. By this time, their protest had become known nationwide as a “sit-in”.
On Thursday, there was trouble. An angry group of white teenagers began shoving（推搡） and cursing them but were quickly removed by the police. By February 10, the sit-in movement had spread to five other states.
By September 1961, more than 70,000 people, both black and white, had participated in sit-ins at segregated restaurants and lunch counters, kneel-ins at segregated churches, read-ins at segregated libraries, and swim-ins at segregated pools and beaches. Over 3,600 people had been arrested, and more than 100 students had been driven away. But they were getting results. On June 10, 1964, the U. S Senate passed a major civil rights bill outlawing（宣布为非法）racial discrimination in all public places. President Lyndon Johnson signed it on July 2, and it became law. But the highest credit still goes to the four brave students from North Carolina who first sat-in and waited it out.
68. In this passage, “sit-in” refers to _________.
A. an activity where people sit together and drink coffee freely
B. a bill which outlaws racial discrimination in all public places
C. a form in which people peacefully sit and decline to leave
D. a polite behavior that everyone enjoys
69. Which statement can be concluded from the fifth paragraph in the passage?
A. The sit-in movement was not successful.
B. The sit-in movement had a positive result.
C. Only black people participated in sit-ins.
D. A lot of protesters were arrested, with some students driven away from school
70. What was the purpose of the civil rights bill passed in 1964?
A. The highest credit went to the four brave students.
B. It declared that segregation was a law.
C. The students were allowed to participate in sit-ins.
D. It made racial segregation against the law in all public places.
71. What is the passage mainly about?
A. Segregation was the law in the South.
B. The first sit-in was in 1960.
C. The sit-ins helped to end segregation.
D. The civil rights bill was passed in 1964 by the U. S. Senate.
