    In most situations, light helps us see. But when it comes to looking at the night sky, light is actually a kind of pollution. It prevents our view of some of life’s most striking sights: stars, planets, and even galaxies.
    “When I was a little boy, I loved the night sky. I remember looking up and the sky was filled with stars. I became an astronomer because I was amazed by their beauty,” says Robert gent, “Now in most big cities kids can’t see the stars like I did.”
    Normally, about 2,500 individual stars are visible to the naked eye without using any special equipment. But because of light pollution, you actually see just 200 to 300 and fewer than a dozen from some cities. Only one in three Americans can see our own galaxy (星系) with the naked eye. Those people live far away from the lights of big cities, office building, and shopping malls.
    Fortunately, there’s an inexpensive and useful way. If we shine lights down at the ground instead of up into the sky, and use lower brightness levels, we can save big amounts of energy and keep the beauty of the night skies. Many cities and towns have passed laws limiting lights at night, making sure enough shine for safety without creating much light pollution.
    Light pollution affects more than our view of the heavens and can harm wildlife. Migrating (迁移) birds sometimes fly over cities and become confused by the brightness, flying in circles until they drop from exhaustion. Sea turtles need dark beaches for nesting and won’t approach bright lights. Too much light at night may even affect human health. For all these reasons, researchers are working on ways to use light only when and where they are truly needed. Everyone deserves to look up at the sky.
    小题1:According to the text, using our naked eyes, ______________.
    A．people in remote areas can see more stars than those in big cities
    B．over one third Americans can see our own galaxy
    C．about one in three Americans in big cities can see our own galaxy
    D．Americans can only see 200 to 300 stars
    小题2:Many cities and towns have passed laws limiting lights at night mainly to _________.
    A．save the electricityB．make sure of cities’ safety
    C．let you count the number of starsD．avoid much light pollution
    小题3:In how many ways will the light pollution do harm?
    A．OneB．TwoC．ThreeD．Four
    小题4:The underlined word “exhaustion” in the last paragraph means “_________”.
    A．air pollutionB．tirednessC．breathD．brightness

    In America, drivers’ education is part of the regular high school curriculum. Every student in his or her second year of high school is required to take a class in driver’s education. However, unlike other courses, it is not given during the regular school year. Instead it is a summer course.?
    The course is divided up into two parts: class time for learning laws and regulations and driving time to practise driving. Class time is not unlike any other class. The students have a text from which they study the basic laws they must know to pass the written driving test that is given to anyone wanting to get a driver’s license.?
    Driving time is a chance for the students to get behind the wheel (steering wheel) and practice starting steering, backing up, parking, switching lanes, turning corners, and all the other maneuvers (操作) required to drive a car. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. The instructor and “driver” sit in the front seats and the other three students sit in the back.?
    Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver’s side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over. The car also has another special feature. On the top of the car is a sign that reads: STUDENT DRIVER. That lets nearby drivers know that they should use extra caution(小心) the student driver is a beginning driver, not very experienced and prone to driving slowly.?
    After the student has passed the driver’s education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), they can go to a designated state office to take their driver’s test, which is made up of an eye examination, a written test, and a road test. The person must pass all three tests in order to be given a driver’s license. If the person did well in his or her driver’s education class, he or she will pass the test with flying colors and get a driver’s license.?
    1. In America, the driver’s course mentioned above___________.
    A. is considered as part of the advanced education?
    B. is given to anyone wanting to get a driver’s license?
    C. is carried on at the same time as other courses?
    D. is offered to all the students of Grade 2 in high schools
    2. To prevent accidents, a drivers Ed car______________.?
    A. has a sign inside it                                B. has two sets of brakes?
    C. is big enough to hold five persons           D. can’t run very fast
    3. We can infer that the students are required to ______ in their whole driving practice.
    A. go out driving for twelve times                     B. spend at least six hours driving?
    C. drive for two hour blocks of time           D. get half an hour driving
    4. Which of the following does not agree with the requirements for the students wanting to get their driver’s license? ?
    A. They must be 16 years of age
    B. They should go to have their driver’s test
    C. They must have their eyes examined
    D. They ought to do well in their driver’s course
    5 In the last sentence, “with flying colors” means______________.?
    A. happily                                                B. successfully           
    C. colorfully                                                D. quickly

    阅读理解下面的短文，然后根据短文内容，指出能完成所给句子或回答所提问题的最佳答案。
    Astronomy (天文学) is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about heavens (天堂). But the six planets that he could see with his eyes alone limited man.
    The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.
    Each new tool added to the field of astronomy helped man reach out into space. Until there were telescopes (望远镜), man did not know much about the moon. He did not know that the planet called Saturn (土星) had rings around it. His sight was so limited that he could not see all the planets. In the early 1700s, people thought there were only six planets. Pluto (冥王星), the last of the nine planets to be discovered was seen until 1930.
    Before the spectroscopes (分光镜), man didn’t know what kind of gas was in the sun or other stars, without radio telescopes (射电望远镜), we did not know that radio noise came from far in space.
    Today, astronomy is a growing science. We have learned more in the past fifty years than in the whole history of astronomy.
    1Thousands of years ago, man watched ____ with his eyes.
    A. the moon       B. the stars         C. the universe    D. all the planets
    2 When the Greeks watched the stars, they could ____ .
    A. know what the stars were made of     B. not see their places in the sky

    Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.
    Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
    This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
    1.The most important points of trees to man is ________.
    A. they help him to make money               B. they give him cool
    C. they give him wood and other things       D. they help him to stop drought and floods
    2.In many places forests slowly disappear because ________ .
    A. many trees have been cut down by man
    B. new trees are not well looked after
    C. man has not paid enough attention to planting trees
    D. all the above
    3.Land becomes desert after all trees are cut down because ________ .
    A. roots of trees break up the soil   
    B. there are too many rainfalls
    C. strong winds bring a lot of sand
    D. there are no longer trees to keep the rain and protect the top-soil.
    4.Which title best fits the passage?
    A. Trees and Man                                      B. The Function of Tree Wood
    C. How do People do with Trees?                  D. The Usage of Tree Roots

    Animation(动画) means making things which are lifeless come alive and move.
    Since earliest times, people have always been surprised by movement. But not until this century have we managed to take control of movement, to record it, and in the case of animation, to retranslate it and recreate it. To do all this, we use a movie camera and a projector.
    In the world of cartoon animation, nothing is impossible. You can make the characters do exactly what you want them to do.
    A famous early cartoon character was Felix the Cat, created by Pat Sullivan in America in the early nineteen twenties. Felix was a wonderful cat. He could do all sorts of things no natural cat could do like taking off his tail, using it as a handle and then putting it back.
    Most of the great early animators lived and worked in America, the home of the moving picture industry. The famous Walt Disney cartoon characters came to life after 1928. Popeye the Sailor and his girl friend Olive Oyo were born at Max Ficischer in 1933.
    But to be an animator, you don’t have to be a professional. It is possible for anyone to make a simple animated film without using a camera at all. All you have to do is to draw directly on to an empty film and then run the film through a projector.
    64. Which of the following statements is TRUE?
    A. People were unable to cause the movement to last or record it in the last century.
    B. Pat Sullivan was a famous early cartoon character.
    C. It is impossible to make cartoon characters do what they are designed to do.
    D. In ancient times people were surprised by movement.
    65. According to the passage, Felix the Cat________.
    A. was created by the American cartoonist Felix
    B. was designed by Pat Sullivan in the early twentieth century
    C. was unable to do what natural cats could not do
    D. was created in the United States in the nineteenth century
    66. It can be inferred from the passage that ________.
    A. Walt Disney’s cartoon characters were born earlier that Pat Sullivan’s
    B. only professionals can create cartoon characters
    C. Popeye the Sailor and Olive Oyo were famous cartoonists
    D. the cartoon industry started in the United States
    67. Which of the following statements best describes the author’s attitude towards cartoon making?
    A. Cartoon making is an easy job. Anyone can do it.
    B. Only trained people can be employed in cartoon making industry.   
    C. Anyone can make cartoons under the instructions of professionals.
    D. Cartoon making is no easy job. You have to spend much time drawing onto the empty film.

    However important we may regard school life to be, we can’t ignore the fact that children spend more time at home than in the classroom. Therefore the great influence of parents can’t be ignored or discounted by the teacher. They can become strong supports of the school or they can consciously or unconsciously prevent the school from accomplishing its aims.
    Administrators have been aware of the need to keep parents apprised of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program and developmental math.
    Moreover, the classroom teacher can also play an important role in explaining to parents what they should do. The informal tea and the many interviews carried on during the year, as well as new ways of reporting pupils’ progress, can significantly aid the interchanged of ideas between school and home.
    Suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent change his method. He might be persuaded to let Junior participate in discussing he family budget, buying the food, using a measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.
    If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in math and at the same time, enjoying the work.
    Too often, however, teachers’ conferences with parents are devoted to unimportant accounts of children’s wrongdoing, complaints about laziness and poor work habits, and suggestions for punishments and rewards at home.
    What is needed is a more creative approach in which the teacher, as a professional advisor, plants ideas in parents’ minds for the best use of the many hours that the child spends out of the classroom. In this way, the school and the home join forces in fostering the fullest development of youngsters’ competence.
    小题1:The underlined phrase “keep parents apprised of” (Line 1, Para. 2) probably means to let parents         .
    A．judgeB．knowC．designD．develop
    小题2:What is the purpose of the schools’ informal tea and interviews?
    A．To improve the relationship between teacher and parents.
    B．To explain to parents the change of the school curriculum.
    C．To report students’ misdoings and suggestions for punishments.
    D．To help develop good communication between school and home.
    小题3:Why does the author provide all example in Paragraph 4？
    A．To help parents to know the importance of home activities.
    B．To show how the teacher can guide in home training.
    C．To prove parents all non professional advisors.
    D．To advice parents to teach kids math at home.
    小题4:From the passage we learn that the author      .
    A．thinks teachers should do better as professionals
    B．is worried about children’s performance at home
    C．is satisfied with the present state of school education
    D．believes time spent out of the classroom has been wasted@m

    Most sharks are dangerous. The largest kind of sharks—the whale shark—has small teeth and is quite harmless to people. However, blue sharks, tiger sharks, white sharks and hammerheads are enemies of man.
    Man-eaters are always a danger to swimmers in shark waters. Sometimes, though, men have used strange methods when they’re suddenly faced with a shark.
    During world War Ⅱ, soldiers and sailors whose boats or planes were destroyed drifted(漂流) helplessly on the ocean in small rafts(筏子). While waiting to be saved, the men had to struggle to stay alive and were often attacked by sharks. In some cases, they had few weapons to protect themselves with. They found that just splashing(溅水) water seemed to help keep the sharks away.
    One sailor was swimming for his life in the Atlantic Ocean after his boat had been blown up. He saw a shark swimming towards him. He hit the shark with his bare fist, and that drove it off.
    Once, in Australia, a fisherman was fishing after sunset. He hooked a big fish and drew it towards the shore. His line broke when the fish was only a few yards from the shore. The fisherman waded(涉水) into the water to try to catch it with his hands. In the dim light, it looked like the kind of fish that could be dealt with without danger.
    He put his arms around the fish and wrestled with it. Dragging it to the beach turned out to be harder than he had expected, but at last he pulled it in. When he turned a light on it, he was amazed. He had caught a shark. It was small for a shark, but it was the man-eating type and was about as long as a tall man.In a word, the best way to deal with sharks is to keep far away from them.
    60. The shark that is least dangerous to man is the ________.
    A. white shark      B. whale shark   C. tiger shark     D. hammerhead shark
    61. This story tells you that sharks are usually ________.
    A. friendly         B. small         C. afraid of people     D. dangerous
    62. After the Australian fisherman found he had caught a shark, he was _________.
    A. surprised      B. frightened      C. unhappy      D. angry
    63. This story tells you that the best way to handle sharks is to ________.
    A. hit them with your fist                 B. keep far away from them
    C. splash water                         D. wrestle with them
    64. The passage mainly tells us something  ________.
    A. about fishing sharks                  B. about sharks
    C. how to eat  sharks                   D. that sharks are man’s enemies
