    After years of hearing drivers complain about scratches on their cars, Japan's Nissan Motor Company has officially announced the next big thing---a paint that not only resists scratches and scrapes, but actually repairs itself within a few days.
    The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin(弹性树脂) that is able to heal minor marks caused by car wash equipment, parking lot encounters, road debris (石头碎片) or even on-purpose destruction. The automaker admits its results vary depending on the temperature and the depth of the damage, but adds this is the only paint like it in the world, and tests prove it works. Minor scratches, the most common type, are said to slowly fade over about a week. And once they're gone, there is no trace that they were ever there. The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period.
    Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents. But the complete auto-healing won't come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 U.S. to the price of a car. It plans to use its new chemical mixture only on its X - Trail SUVs in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven't been made yet, if it's a hit there, you can be almost sure market forces will drive it to these shores, as well.

    1. 1.

      From the article, we can find that_______.

      1. A.
        the paint has already been used on cars by now
      2. B.
        it beats other products of its kind in its lengthy effect
      3. C.
        car damage is mainly caused by scratches and scrapes
      4. D.
        marketing this paint in Europe is not under way

      The paint used on cars can______.

      1. A.
        last 3 years before it is re-applied again
      2. B.
        fade only in a few days
      3. C.
        help to protect cars from minor paint damage
      4. D.
        reduce car scrape incidents to 20 percent
    3. 3.

      What can be inferred from the article?

      1. A.
        The paint was developed by Nissan Motor Company.
      2. B.
        The paint might work better in summer than in winter.
      3. C.
        The mark on the car could disappear as soon as the paint is applied.
      4. D.
        The paint is very popular in Japan.

    It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other parts.
    The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
    And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.

    1. 1.

      The first paragraph tells us that _____.

      1. A.
        all living things in nature depend on each other
      2. B.
        everything in nature can’t exist without the help of man
      3. C.
        man has known the importance of the balance of nature for a long time
      4. D.
        no living thing can live naturally
    2. 2.

      In the second paragraph the examples given are used to prove that _____.

      1. A.
        all forms of life belong to a system in which all the parts can be changed for one another
      2. B.
        it is only during the last few years that man has generally known the balance of nature
      3. C.
        there are some living things which can exist by themselves without change
      4. D.
        we can’t change one form of life without destroying the balance of nature
    3. 3.

      The last paragraph suggests that in order to get his immediate benefits(利益) _____.

      1. A.
        man is always anxious to control his activities within limits
      2. B.
        man is always too eager in planning for distant future
      3. C.
        man often fails to think about their future results of his action
      4. D.
        man often feels that he will have to give up in despair
    4. 4.

      Which of the following is true according to the passage?

      1. A.
        Cutting down woods does little harm to human beings.
      2. B.
        Man has to pay much more attention to the future results of his present action.
      3. C.
        Oxygen comes from forests.
      4. D.
        The passage tells us to try our best to get as much as possible immediately.

    In a family where the roles of men and women are not sharply separated and where many household tasks are shared to a greater or lesser extent, notions (观念) of male superiority are hard to maintain.
    The pattern of sharing in tasks and in decisions makes for equality, and this in turn leads to further sharing. In such a home, the growing boy and girl learn to accept that equality more easily than their parents did and to prepare more fully for participation in a world characterized by cooperation rather than by the “battle of the sexes”.
    If the process goes too far and man's role is regarded as less important and that has happened in some cases 一 we are as badly off as before, only in reverse.
    It is time to reassess (重新确定) the role of the man in the American family. We are getting a little tired of“Momism”一 but we don't want to exchange it for a “neopopism”. What we need, rather, is the recognition that bringing up children involves a partnership of equals. There are signs that psychiatrists, psychologists, social workers, and specialists on the family are becoming more aware of the part men play and that they have decided that women should not receive all the credits 一 nor all the blame. We have almost given up saying that a woman's place is in the home. We are beginning, however, to analyze man's place in the home and to insist that he does have a place in it. Nor is that place irrelevant(不相关的 ) to the healthy development of the child.
    The family is a cooperative enterprise for which it is difficult to lay down rules, because each family needs to work out its own way for solving its own problems.
    Excessive authoritarianism (权力主义 ) has unhappy consequences, whether it wears skirts or trousers, and the ideal of equal rights and equal responsibilities is pertinent (有关系的 ) not only to a healthy democracy (民主 ) but also to a healthy family.

    1. 1.

      Sharing the tasks and decisions in the home leads to        

      1. A.
        A masculine (男子气的) women  
      2. B.
        inequality    
      3. C.
        effeminate men 
      4. D.
        further sharing
    2. 2.

      The danger in the sharing of the household tasks by the mother and father is that __

      1. A.
        the role of the father may become an inferior (次要的) one
      2. B.
        the role of the mother may become an inferior one
      3. C.
        the children will grow up believing that life is a battle of the sexes
      4. D.
        the father will be less capable in his profession
    3. 3.

      The author states that bringing up children        

      1. A.
        is primarily the mother' s job            
      2. B.
        belongs among the duties of the father
      3. C.
        belongs to the one who is free more often   
      4. D.
        involves partnership of equals

    During the school year many parents take on the role of driver as they drive their children from one lesson to another .Understandably so. Many of us want our children to have a little taste of everything, from organized sports to music, dance and more. But we can overdo it, leaving our children feeling a little burnt out, and according to parent educator Diane Loisie ,it’s their school work which suffers the most. “After school, if they’re busy in a number of sporting events, besides they need to do their homework, then the time they’ll feel sleepy is in the classroom. Your child needs free time. So if you’re filling up that after school time, then it’s during the day that they’re going to be taking a break.”
    Professor Claire McDermott agrees that there’s a lot to be gained from sometimes putting those scheduled lessons and activities away. “Relaxing time is important for children. It’s time just to do the things they want to do. A child can go up to their room, or they can play around. It doesn’t look like productive time; parents certainly wouldn’t be saying ‘Wow, are they ever learning things now?’ But this relaxing time gives both the body and the brain just a wonderful chance to relax after a day. It helps a child prepare for sleep, but it also helps to understand the learning that’s gone on that day.”
    It’s hard to prevent signing our kids up for some activities and lessons. After all, many of us want our children to have a head start in life and the chance to join in great activities in the arts or sports is a part of that. However, Loisie feels that in the long run most children feel better with just a few key activities because it gives them an opportunity to master them. “When we get our children in too many activities because we want our children to experience everything, then what we’re doing is setting them up not to be good at one thing or gaining a skill.” So choose your children’s activities wisely. It may be one of the best things you’ve ever done for your kids… and for the family drivers!

        It is helpful
      3. C.
        It is a bad habit
      4. D.

    3. 3.

        Because children have no time

    Want to take an out-of-this-world trip? Richard Branson's Virgin Galactic plans to make that possible. Beginning in 2009, people should have the opportunity to become space tourists, traveling at about 3,000 mph to heights about 75 miles above Earth. Branson has high hopes for his latest plans. "It is just the start of what we believe will be a new age in the history of mankind—one day making the affordable exploration of space by human beings a real possibility," he said.  
    At the start, though, the trip won’t be cheap. Seats aboard Virgin’s first craft—VSS Enterprise—will cost about $200,000. Prices could drop after the first hundred space flights. Despite the current ticket cost, more than 30,000 people—including celebrities(名人) Sigourney Weaver and Victoria Principal—have expressed interest in getting onboard.  
    People who don't have an extra $200,000 still have a chance to get a seat aboard the craft. A computer game contest and a reality television show are in the works. Those who can’t afford a ticket will have an opportunity to win a seat.   
    Virgin is expected to be the first commercial spacecraft. It will hold six passengers and two pilots. Passengers will be able to see the Earth from many different viewpoints. The cabin will include 15 floor-to-ceiling windows, allowing for views that extend about 1,000 miles in any direction.
    Passengers will have three days of preflight preparation. On the big day, the spacecraft will take off from the Mojave Spaceport in the California desert. The craft will rocket passengers into space at four times the speed of sound. The journey will last about 2 1/2 hours. Passengers will wear spacesuits and helmets(头盔). They will be able to float around the cabin and do somersaults(空翻) during the five minutes of weightlessness they will experience in zero gravity. At the end of the flight, the craft will land on a runway.

    1. 1.

      Virgin Galactic could be _____.

      1. A.
        the engineer of the first commercial spacecraft
      2. B.
        the name of a series of spacecrafts
      3. C.
        the company of the first commercial spacecraft
      4. D.
        a passenger aboard the first commercial spacecraft
    2. 2.

      The space passengers will do all the following except that _____.

      1. A.
        they will receive a three-day training course
      2. B.
        they will wear spacesuits and helmets
      3. C.
        they will take about $200,000 with them
      4. D.
        they will experience weightlessness
    3. 3.

      Which statement is true according to the passage?

      1. A.
        More than 30,000 people have got to travel in spacecraft.
      2. B.
        Many people signed up for space travel in spite of the high ticket cost.
      3. C.
        Those without much money could also go space travel without occupying the seats.
      4. D.
        The first commercial spacecraft will have six persons on board.
    4. 4.

      What is the text mainly about?

      1. A.
        The exciting moment of the spacecraft’s launching.
      2. B.
        The living condition of space tourists in the craft.
      3. C.
        Preparations for a space travel.
      4. D.
        Plans for the first commercial space flight.
