         The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures(生
    物) from the earth.This idea may sound like something from a science fiction (科幻小说), but it is
    actually being taken seriously by many researchers.
         This suggested future for the "red planet" will be the main topic for discussion at an international
    conference hosted by NASA (美国宇航局) this week.Leading researchers as well as science fiction
    writers will attend the event.It comes as NASA is preparing a multibilliondollar Mars research programme."Turning Mars into a little earth has long been a topic in science fiction,  "said Dr Michael Meyer, NASA's senior scientist for astrobiology (太空生物学). "Now, with scientists exploring the reality, we can
    ask what are the real possibilities of changing Mars."
         Most scientists agree that Mars could be turned into a little earth, although much time and money
    would be needed to achieve this goal.
         But many experts are shocked by the idea."We are destroying our own world at an unbelievable
    speed and now we are talking about ruining another planet,  " said Paul Murdin, of the Institute of
    Astronomy, Cambridge, UK.Over the past months, scientists have become increasingly confident they
    will find Martian life forms.Europe and America's robot explorers have found proof that water, mixed
    with soil, exists in large amounts on the planet.
         In addition, two different groups of scientistsannounced on March 28 that they had found signs of
    methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and
    could be produced by microbes (微生物) living in the red planet's soil.
         But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be
    put in danger by the little earth project."Before we have even discovered if there is life on Mars, we are
    talking about carrying out projects that would destroy all these native life forms, all the strange microbes
    that we hope to find buried in the soil,  " said Dr Pratt.This view is shared by Monica Grady, a planetary
    scientist at the Natural History Museum, London."We cannot risk starting a global experiment that would wipe out the precious information we are looking for." she said, "This is just wrong."

         Margaret Cook is a professional, married woman with two young children. The elder, who is four, has
    just started at a local primary school. It is a school that she was eager for her daughter to attend because
    it has a mix of racial and social cultures. As a white from a middle-class family, she thought it important for her daughter to go to a local school that was representative of the cultural and social mix of the society in
    which we live. Having met, however, some of the other parents and children, she's becoming increasingly
    unsure about her choice. She is worried that along with the accent and vocabulary of her classmates, her
    daughter will also pick up what appears to be a very narrow-minded, uneducated attitude. She wants her
    daughter to be able to adapt and to fit in with her friends at school, but not necessarily to model her
    behaviour on theirs. She wants her to like them but not be like them.
         Is she worrying unnecessarily? Or should she abandon her principles and send her children to private
    school? A report, published by the Independent Schools Council, shows record numbers of parents want
    to send their children to private schools that stress "moral standards" and classroom discipline as they lose
    faith in state education, even many Labour voters would consider going private for the first time if they
    could afford the fees.
         But is it right without question to see private schools as heavens where moral standards are high,
    teachers are models of correctness and learning, children all come from open-minded families, and where
    our little ones will be protected from the ills of the world? The only difference is that those who can afford
    school fees are in the habit of making expensive mistakes. One of my colleagues who sends all his children to private schools tells stories of drug abuse, troublemakers, the decline of discipline and ever younger
    age of rebellion (叛逆).
         It's an excellent plan to send our children to a mixed school. Placed in an entirely new environment,
    they are at the risk of rejection, bullying (欺负) and maybe long-term alienation (疏离).But as soon as
    our children step out of the front door they are faced with a challenging world where boundary between
    the good and bad is so complex that young people have difficulty telling them apart. For this reason I
    believe that Cook is better advised to bring her children up in the real world.
    1. From this passage we know that the woman's daughter _______.
    A. is changing others' behavior          
    B. is mixing with trouble-makers
    C. is attending a mixed school          
    D. is applying for a private school
    2. The mother wants her daughter to be _______.
    A. popular and attractive              
    B. a fighter against social ills
    C. a model for her classmates          
    D. open-minded and well-educated
    3. What does the writer think of the private school?
    A. It's a heaven of pleasure.            
    B. It is going from bad to worse.
    C. It is experiencing moral decline.      
    D. It's a place of high moral standard.
    4. The writer suggests sending kids to a mixed school because he thinks _______.
    A. it is well managed                  
    B. it is close to the real world
    C. kids there are well protected            
    D. the competition there isn't fierce

    With the possible exception of equal rights, perhaps the most heated argument across the United States today is the death penalty (死刑).Many argue that it is an effective deterrent（威慑）to murder, while others think there is no enough proof that the death penalty reduces the number of murders.

    The argument advanced by those opposed to the death penalty is that it is cruel and inhuman punishment, that it is the mark of a bad society and finally that it is of questionable effectiveness as a deterrent to crime anyway.

    In our opinion, the death penalty is a necessary action. Throughout recorded history there have always been those peculiar persons in every society who made terrible crimes such as murder. But some are more dangerous than others.

    For example, it is one thing to take the life of another in time of blind anger, but quite another to coldly plan and carry out the murder of one or more people in the style of a butcher. Thus, murder, like all other crimes, is a matter of different degree. While it could be argued with some reason that the criminal in the first instance should be merely kept from society, such should not be the fate of the latter type murderer.

    The value of the death penalty as a deterrent to crime may be open to discussion. But the majority of people believe that the death penalty protects them. Their belief is proved by the fact that the death penalty prevents murder. For example, from 1954 to 1963,when the death penalty was carried out from time to time in California, the murder rate remained between three and four murders for each 100 000 population. Since 1964 the death penalty has been done only once, and the murder rate has risen to 10.4 murders for each 100 000 population. The sharp climb in the state’s murder rate, which began when killings stopped, does not happen by chance. It certainly shows that the death penalty does deter many murderers. If the law about death penalty is vetoed(否决),some people will be murdered—some whose lives may have been saved if the death penalty were in effect. This is really a life or death matter. The lives of thousands of people must be protected.

    1.The main purpose of this passage is to ______.

    A. speak for the majority

    B.support a veto

    C.speak ill of the government

    D.argue for the value of the death penalty

    2.Which of the following is among the heated arguments across the USA besides death penalty?

    A. Air pollution.　　　　　　　　　　　　　　　　　　　　　　    B.The war against Iraq.

    C.Equal rights.　　　　　　　　　　　　　　　　　　　　　　　　 D.Election of president.

    3.The numbers in the last paragraph show that______.

    A. if they stick to death penalty, the number of murders will be reduced

    B.death penalty almost stopped from 1954 to 1963

    C.the population of California has risen

    D.death penalty is of little value

    4.It can be inferred that the writer thinks that ______.

    A. the death penalty is the most important problem in the United States today

    B.the second type of murderers(in Paragraph 4) should be sentenced to death

    C.the veto of the law about death penalty is of little importance

    D.the value of the death penalty as a deterrent to crime is not to be discussed
