    It's not the flashiest car in the world. Not even close. But the 1971 Volkswagen named Helioscan do something most cars can't: nm on solar energy – energy from the sun's light and heat!
    Joshua Bechtold, 14, and the other students at the Riverside School in Lyndonville, Vermont, worked many months to get Helios ready for the 1999  American Tour de Sol （"Sol" is the Latin word for "sun"）. They named their car after Helios, the sun god in Greek mythology（神话）.
    The 4-year-old Tour de Sol encourages the use of "green", or environmentally friendly, cars to help reduce pollution and save energy. It’s not a race. Cars are  judged on fuel efficiency（耗油量） rather than speed. In the week-long event, 44 cars took the 350-mile tour from Waterbury, Connecticut, to Lake George, New York. Of the 23 student cars, Helios was the only one built by middle school students.
    A teacher drove Helios, but the children talked with people wherever they stopped along the mad. "That was my favorite part," says Anna Browne, 15. "We explained how the car runs.”
    Due in part to old, inefficient batteries（电池）, Helios finished fourth - out of four - in its kind, the sun-powered class. "We were there for the fun of it," Anna says. "We're proud of Helios," says Ariel Gleicher, 14. "It's a car that's good for the environment."
    64. What is special about the car Helios in the text?       
    A. It was built by middle school students.
    B. It has an attractive design.
    C. It was made in 1971.
    D. It won the fourth prize.
    65. How many sun-powered cars took part in the race?      
    A. 1.       B. 4.     C. 23.    D. 44.
    66. What would be the best title for the text.'?       
    A. The Making of Helios
    B. 1999 American Tour de Sol
    C. Sun-powered Cars on the Road
    D. Use of Green Cars in Connecticut
    67. The students felt proud of Helios because______.
    A. it could run as far as 350 miles     B. it was favored by many children
    C. it had high-quality batteries         D. it was driven by clean energy

    64---67   ABCD

    People and the sources of air pollution are found in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes from cars. Statistics show that 93 percent of all auto trips are within cities. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country.
    On the average, we throw away more trash and garbage than the year before. The burning of garbage contributes to air pollution. Many major industries are also responsible for the dirty air in the around cities. The fumes from iron, steel, chemical, and petroleum production add particles to the air.
    The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy for traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode. In some of the larger cities, these fumes endanger the live of human beings by contributing to lung diseases and causing early death.
    15．The key point of the passage is that _________.
    A. the cause of air pollution is people
    B. the causes and the effects of air pollution are both found in cities
    C. the effects of air pollution range from headaches to death
    D. air pollution is caused by dirty air
    16．What is the purpose of this passage?
    A. to persuade people to stop polluting the air
    B. to tell the causes of air pollution
    C. to tell why cities are bad places to live

    The science of physics today is as current as the morning newspaper. Indeed,as
    a result of new advances in physics and their rapid application to inventions designed to satisfy man's wants, the world ?itself? has been changing rapidly. Space technology, industrial technology, and the technology of the home, the farm, the office, the bank, and the department store have all been revolutionized.
    Clearly, every grown?up today would understand the world he lives in much better if he knew something about physics. Whether it be Congress(美国国会) voting huge sums of money for new ?warships,? space exploration, or atomic energy；the office staff learning to use a new computer；son Bobby wanting to know about going to the moon；or the housewife learning to operate a new electric stove physics seems to be everywhere.
    Teachers in thousands of schoolrooms in America are trying to communicate some of the excitement and importance of these new developments to their students.
    They know that some of their eager students will someday be scientists and will them selves then contribute(贡献) to the development of new knowledge or its application to new things.
    But in any case, they can be sure that if they bring a knowledge of science(any science) to their students in meaningful and stimulating ways, they have contributed much to helping each one live a more meaningful life.
    1.The application of new advances in physics to inventions ________ .
    A.may solve all the problems in teaching

    Move Earth—it’s no science fiction
    LONDON-Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets（彗星）in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
    This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA） engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
    The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams
    ,needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
    “Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,”Laughlin said.
    Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
    In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）—by cooking us.
    That’s why the group decided to try to save Earth.
    The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.
    There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position it is “most likely the Moon would be stripped away from Earth,” it states. This would greatly change our planet’s climate.
    1. What makes the scientists plan to move Earth?
    A. A few comets are moving to the direction of Earth.
    B. Earth’s working life is coming to an end soon.
    C. Earth will become too hot for mankind to keep alive.
    D. The moon is moving farther and farther away from Earth.
    2.If the plan is successful, Earth will have a working life of ______years.
    A.12 billion                  B.6 billion                    C.18 billion                  D.24 billion
    3.What serious problems might the plan cause according to the passage?
    A. The comet might hit Earth and man might lose the moon.
    B. Earth might be moved too far away and man might be frozen to death.
    C. The comet might hit Jupiter or Saturn and never return to Earth.
    D. Earth’s working life might be greatly shortened.
    4.What does the underlined word “compromise” mean?
    A. provide                    B. benefit              C. share     D. endanger
    5.Which of the following best shows how the plan would work?

    How Long Can People Live?
    She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121 st birthday.
    When it comes to long life, Jeanne Calment is the world’s record holder. She lived to the ripe old age of 122. So is 122 the upper limit to the human life span（寿命）? If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150－or beyond?
    Researchers don’t entirely agree on the answers. “Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135,” says Jerry Shay at the University of Texas.
    Steve Austad at the University of Texas agrees. “People can live much longer than we think,” he says. “Experts used to say that humans couldn’t live past 110. When Calment blew past that age, they raised the number to 120. So why can’t we go higher?”
    The trouble with guessing how old people can live to be is that it’s all just guessing. “Anyone can make up a number,” says Rich Miller at the University of Michigan. “Usually the scientist who picks the highest number gets his name in Time magazine.”
    Won’t new anti-aging techniques keep us alive for centuries? Any cure, says Miller, for aging would probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the life span of mice by 50 percent at most. So, if the average human life span is about 80 years, says Miller, “adding another 50 percent would get you to 120.”
    So what can we conclude from this little disagreement among the researchers? That life span is flexible（有弹性的）, but there is a limit, says George Martin of the University of Washington. “We can get flies to live 50 percent longer,” he says. “But a fly’s never going to live 150 years.” Of course, if you became a new species （物种）, one that ages at a slower speed, that would be a different story, he adds.
    Does Martin really believe that humans could evolve （进化）their way to longer life? “It’s pretty cool to think about,” he says with a smile.
    72. What does the story of Jeanne Calment prove to us?
    A. People can live to 122.       B. Old people are creative.
    C. Women are sporty at 85.     D. Women live longer than men.
    73. According to Steve Austad at the University of Texas, ______.
    A. the average human life span could be 110
    B. scientists cannot find ways to slow aging
    C. few people can expect to live to over 150
    D. researchers are not sure how long people can live
    74. Who would agree that a scientist will become famous if he makes the wildest guess at longevity?
    A. Jerry Shay.          B. Steve Austad     C. Rich Miller     D. George Martin
    75. What can we infer from the last three paragraphs?
    A. Most of us could be good at sports even at 120.
    B. The average human life span cannot be doubled
    C. Scientists believe mice are aging at a slower speed than before.
    D. New techniques could be used to change flies into a new species

    Diane Arbus is known for creating intense black and white photographs of very unusual people. She used a special camera that produced square shaped images. One art expert said Diane Arbus turned photography inside out. Instead of looking at her subjects, she made them look at her.
    Diane Arbus was born in 1923 to a wealthy family in New York City. After finishing high school at the age of 18, Diane married Allan Arbus. Mr. Arbus worked in the advertising department of her father’s store.
    It was Mr. Arbus who gave Diane her first camera. Diane soon decided to take a class with the famous photographer Berenice Abbott. The Arbuses eventually started taking photographs of clothing. These images were used as advertisements for Diane’s father’s store. After the birth of their daughter, Doon, the Arbuses started a business together. Their purpose was to photograph clothing fashions. Diane Arbus was the stylist. She would prepare the hair and faces of the fashion models who wore the clothing being photographed. Allan Arbus took the pictures.
    The couple soon had jobs from important fashion magazines such as “Vogue” and “Harper’s Bazaar”. Their work was very successful during the 1950s. They became part of a group of artists that were helping to redefine visual culture. They were breaking with past traditions to create a new look for a new decade, the sixties.
    But Diane was not satisfied with her secondary role. She wanted a more active part in making photographs. She wanted to explore her own artistic expression and freedom. To do this, she stopped working with her husband. Then she started taking photography classes at the New School in New York City.
    Arbus’ teacher, Lisette Model, influenced her in many ways. She showed Diane how to use a camera like an expert. She also taught Diane to use her art to face her doubts and fears. Miss Model once said that Diane soon started “not listening to me but suddenly listening to herself.”

    Many years ago my student asked me the question, "Mrs. Kindred, why do you teach?" Without taking time to reflect, I answered, "Because someday I might say something that might make a difference in someone's life." Even though I was sincere, that wasn't a very good answer and my student didn't let it slide.
    "Let me get this straight," he said, "You went to college for four years so you could come here every day because you have the hope that someday you might say something that will influence someone?" He shook his head as if I were crazy and walked away looking confused. I'm one of those people who look back and wish they had said something smart or witty, or swift.
    Even though that particular student might no longer wonder why I teach, there are days when I wonder. On those days, I remind myself of the real reasons I teach:
    It's in my blood. My mother was my most influential teacher, and she was a 6th grade reading teacher until her death in 1990. She instilled(逐渐灌输) in me a love of reading and the knowledge that education opens doors.
    Teaching is a way to make a difference. If you throw a stone in a pond the ripples go on and on until they reach the shore. You can't have ripples without a "stone." Good teachers throw stones that make a positive difference, and that's what I strive to do.
    I genuinely love teenagers. I want to share with others what I know and what I have learned through the years. Life is full of ups and downs, and if I can help students avoid some potholes on the road of life, I want to do so. If they'll allow me to celebrate their victories with them, I want to do too.
    Teaching isn't for everyone, but I know I made the right career choice.
    小题1:Why did the student continue to ask the question about the writer’s being a teacher?
    A．Because he thought her answer was unbelievable.
    B．Because the writer was insincere.
    C．Because the student was naughty.
    D．Because the answer was difficult to understand.
    小题2:What do you think of the writer?
    A．Stupid. B．Honest.C．Conservative.D．Polite.
    小题3:According to the text, which of the following is NOT true?
    A．The writer’s mother has the greatest influence on her.
    B．The writer’s answer made the student confused.
    C．In the writer’s opinion, some people in the world are unfit to teach.
    D．The writer annoyed the student who asked the question.
    小题4:We can infer from the text that _________.
    A．the writer was also a good teacher in school
    B．the writer often plays with her students beside a pond
    C．the writer devotes herself to teaching and her students
    D．the writer often accompanies the students on their way home
    小题5:What’s the main idea of the text?
    A．A student’s silly question.B．A good teacher who likes students.
    C．A confused student.D．The reason why I teach.

    Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase of world population in countries continues at the present rate, there may be much greater harm to human beings. Some scientists speak of the increase in numbers of people as “population pollution.”
    About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2,000. If the population continues to grow at the same rate, there will be 25 billion in the world a hundred years from now.
    Man has been using the earth’s resources more and more rapidly over the past years. Some of them are almost used up. Now many people believe that man’s greatest problem is how to control the growth of the population. The material supplies in the world will be far from enough to support the human population, in time to come, if the present rate of increase continues. Already there is overcrowding in many cities and starvation in some countries. Should man’s population keep on growing so rapidly as before? Many people believe that human survival in the future depends on the answer to this question.
    59. The rapid increase in population is considered to be __________.
    A. the increase of resources          B. population pollution
    C. the development of mankind       D. the present rate
    60. The world population will be _________ by the year 2,000.
    A. 7 billion                  B. 250 million       C. 25 billion      D. 3.5 billion
    61. If the present rate of increase continue, ________________.
    A. the world is going to end
    B. the earth won’t be able to support the growing population in the future
    C. pollution has nothing to do with the rapidly increasing population
    D. there would be four billion in the world a hundred years from now
    62. Which of the following is WRONG according to the passage?
    A. In 1850 the world population reached a billion.
    B. Man must fight a battle against population pollution.
    C. The world’s population is increasing with years.
    D. All of the earth’s resources are gone now.
