         "In only six days I lost seven pounds of weight."
         "Two full inches in the first three days!"
          These are the kinds of statements used in magazine,newspaper,radio and television ads,
    promising new shapes and new looks to those who buy the medicine or the device.The
    promoters of products say they can shape the legs,slim the face,smooth wrinkles,or in some
    other way to add to beauty or desirability.
          Often such products are nothing more than moneymaking things for their promoters.The
    results they produce are questionable,and some are dangerous to health.
    To understand how these products can be legally promoted to the public,it is necessary to
    understand something of the laws covering their regulation.If the product is a drug,FDA
    (Food and Drug Administration)can require proof under the Food,Drug,and Cosmetic Act
    that is safe and effective before it is put on the market.But if the product is a device,FDA
    has no authority to require premarketing proof of safety or effectiveness.If a product already
    on the market is a danger to health,FDA can request the producer or distributor to remove it
    from the market voluntarily,or it can take legal action,including seizure(查封)of the product.
         One notable case a few years ago involved an electrical device called the Relaxacisor,which
    had been sold for reducing the waistline.The Relaxacisor produced electrical shocks to the body
    through contact pads.FDA took legal action against the distributor to stop the sale of the device
    on the grounds that it was dangerous to health and life.
         Obviously,most of the devices on the market have never been the subject of court proceedings
    (法律诉讼),and new devices appear continually.Before buying,it is up to the consumer to judge
    the safety or effectiveness of such items.
    1．It can be inferred that the ads mentioned in the text are________.
    A．objective  
    B．costly
    C．unreliable  
    D．illegal
    2.Which of the following is TRUE according to the text?
    A．The court is in charge of removing dangerous products.
    B．New products are more likely to be questionable.
    C．The production of a device must be approved by FDA.
    D．The promoters usually just care about profits.
    3．FDA can ask for the proof of safety and effectiveness of a product________.
    A．if it is a drug
    B．if it is a device
    C．if its consumers make complaints
    D．if its distributors challenge FDA's authority
    4．The Relaxacisor is mentioned as________.
    A．a product which was designed to produce electricity
    B．a product whose distributor was involved in a legal case
    C．a successful advertisement of a beauty product
    D．an example of a quality beauty product
    5．The author intends to________.
    A．make consumers aware of the promoters' false promises
    B．show the weakness of the law on product safety
    C．give advice on how to keep young and beautiful
    D．introduce the organization of FDA

         In 2006,I spent 3 glorious weeks in South Africa.It was my first time traveling on the African continent and truly each day was filled with one adventure after another.That was the craziest and the most
    dangerous experience I have ever had.
         On the morning of the excursion,I met with my friends for breakfast,with little conversation.I supposed
    we were nervous about the day ahead of us.The coach then drove us from Cape Town to Dyer Island in
    Gansbaii.
         As soon as we got to our destination,we were quickly pushed into a boat.About 2 hours into the boat
    we spotted our first shark.It was one of the world's deadliest predators(食肉动物)-a Great White shark
    Our guide told us that we had to get into the water immediately.Without any formal preparation or
    instruction,we put our thick wet suits on and jumped into the iron cage.
         There I was in this tiny cage with 3 Great White sharks circling around me.I tried desperately to take
    pictures with my underwater camera,not letting my hands and feet drift(漂)out of the cage.
         When I took a breath,life above the water seemed chaotic(混乱的)．But,I would drop back under
    the water and life would seem to stop existing.And the sharks that always appeared frightening on TV or
    in photographs actually appeared peaceful in person.
         After an hour,I decided it was probably time for me to get out once the sharks started to become
    really aggressive.I waited until the very last second I could,since I knew I would probably never do this
    again.

        In college , Spring Break (春假) is usually associated with the beach, parties and sleepless nights,
    bringing about relaxation, free time and friends. Students who wish to spend their break doing
    something productive and rewarding, however, may choose to participate in the Altemative Break

    opportunity to learn about members of communities and broaden their view. In turn, they will
    incorporate (融合) their experiences and lessons learned into their own communities. In a word ,
    the Program aims to encourage students to be active citizens and engage themselves in making a
    difference in society.

    Program.

    including trips to New Orleans, India and Dominican Republic. "I was a student who went on alternative
    break trips and had my life totally transformed by that experience , " she said. " Every year , we meet
    many students who have attended the Program. You can see changes in their life that are connected
    with their altemative break experiences. "
         The Program began in  1991. Today , it  has  become  increasingly popular with college students
    in the United States.

         In the United States,train transportation is unpopular compared with cars and airplanes. Most
    people like traveling by car or by air.
         Officials of the United States Department of Transportation made a study in 2001. The study is
    about how many miles Americans traveled by different means of transportation. They only studied
    trips longer than 50 miles. The study showed that fifty-six percent of all miles were traveled in
    personal vehicle. Forty-one percent were traveled in an airplane. Two percent were traveled in a
    bus. And less than one percent of miles were traveled in a train.
         Amtrak is the national provider of train transportation in the United States. In the past ten years,
    the number of its passengers has increased by eighteen percent. Although the number of passengers
    has increased,it is still very small now. In countries such as France,Germany,or Japan,more people
    use trains.
         There are several reasons why many people __________________________.
         Firstly,Americans love to drive their own cars. On highways,cars can travel as fast as trains.
    These highways connect all major cities in America. Secondly,many travelers like to be independent.
    When they use their own cars they can decide when to travel. Thirdly,many buses travel between
    major cities. Bus travel is less costly than train travel.
         In a huge country like the United States,cities are far away from each other. In some cases,trave
    l from one city to another by train may take more than a day. Airplanes can carry passengers over
    long distances much faster. People who do not want to spend long time traveling by train decide to
    fly. For these people saving time is the most important thing    .

         In bringing up children, every parent watches eagerly the child's acquisition of each new
    skill-the first spoken words, the first independent steps, or the beginning of reading and writing.
    It is often tempting to hurry the child beyond his natural learning rate, but this can set up
    dangerous feelings of failure and states of worry in the child. This might happen at any stage.
    A baby might be forced to use a toilet too early, a young child might be encouraged to learn
    to read before he knows the meaning of the words he reads. On the other hand, though, if a
    child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm
    for life and his desire to find out new things for himself.
         Parents vary greatly in their degree of strictness towards their children. Some may be
    especially strict in money matters, others are severe over times of coming home at night or
    punctuality for meals. In general, the controls imposed represent the needs of the parents and
    the values of the community as much as the child's own happiness.
         As regards the development of moral standards in the growing child, consistency is very
    important in parental teaching. To forbid a thing one day and excuse it the next is no foundation
    for morality (道德). Also, parents should realize that "example is better than precept". If they
    are not sincere and do not practice what they preach (说教),their children may grow confused
    and emotionally insecure when they grow old enough to think for themselves, and realize they
    have been to some extent fooled.
         A sudden awareness of a marked difference between their parents' principles and their
    morals can be a dangerous disappointment.
    1. Eagerly watching the child's acquisition of new skills         .
    A. should be avoided
    B. is universal among parents
    C. sets up dangerous states of worry in the child
    D. will make him lose interest in learning new things
    2. In the process of children's learning new skills parents          .
    A. should encourage them to read before they know the meaning of the words they read
    B. should not expect too much of them
    C. should achieve a balance between pushing them too hard and leaving them on their own
    D. should create as many learning opportunities as possible
    3. The second paragraph mainly tells us that         .
    A. parents should be strict with their children
    B. parental controls reflect only the needs of the parents and the values of the community
    C. parental restrictions vary, and are not always enforced for the benefit of the children alone
    D. parents vary in their strictness towards their children according to the situation.
    4. The underlined word"precept" in Para.3 probably means"         "
    A. idea    
    B. punishment        
    C. behaviour        
    D. instruction
    5. In moral matters, parents should         .
    A. observe the rules themselves
    B. be aware of the marked difference between adults and children
    C. forbid things which have no foundation in morality
    D. consistently ensure the security of their children
