Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene（基因）is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument，in terms of morality or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations. Then the other clone would be as well. The latter could foe inserted in the woman and allowed to ripen to term. Moreover，cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single(or more) organ(s）.It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle”of life. There would be a large number of same genes., which reduce the chances of improvement，and, in turn, development-the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappea. Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as “objects” rather than people in the society.Scientists haven’t 100 percent. guaranteed that the first cloned will be normal. Thus this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades: of it. I believe that cloning is only legal if its purpose is for cloning organs, not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable.

4.Which of the following shows the structure of the passage
American society is not nap (午睡)-friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine, “There’s even a prohibition against admitting we need sleep”. Nobody wants to be caught napping or found asleep at work. To quote a proverb: “Some sleep five hours, nature requires seven, laziness nine and wickedness eleven.”
Wrong. The way not to fall asleep at work is to take naps when you need them. “We have to totally change our attitude toward napping,” says Dr. William Dement of Stanford University, the godfather of sleep research.
Last year a national commission led by Dement identified an “American sleep debt” which one member said was as important as the national debt. The commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, President Clinton is trying to take a ha1f-hour snooze (瞌睡) every afternoon.
About 60 percent of American adults nap when given the opportunity. We seem to have “a mid afternoon quiet phase,” also called “a secondary sleep gate.” Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap.
We Superstars of Snooze don't nap to replace lost shut-eye or to prepare for a night shift.Rather, we “snack” on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, cars, planes and on boats; on floors and beds; and in libraries, offices and museums.
1.It is commonly accepted in American society that too much sleep is .
A．unreasonable B．criminal C．harmful D．costly
2.The research done by the Dement Commission shows that Americans ________.
A．don't like to take naps
B．are terribly worried about their national debt
C．sleep less than is good for them
D．have caused many industrial and traffic accidents
3.The purpose of this article is to .
A．warn us of the wickedness of napping
B．explain the danger of sleepiness
C．discuss the side effects of napping
D．convince the reader of the necessity of napping
4.The underlined phrase “American sleep debt” in Para. 3 is the result of .
A．the traditional misconception the Americans have about sleep
B．the new sleep policy of the Clinton Administration
C．the rapid development of American industry
D．the Americans' worry about the danger of sleepiness
5.The second sentence of the last paragraph tells us that it is .
A．preferable to have a sound sleep before a night shift
B．good practice to eat something light before we go to bed
C．essential to make up for cost sleep
D．natural to take a nap whenever we feel the need for it
Drunken driving sometimes called American's socially accepted form of murder has become a national epidemic（流行病）．Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past ten years．A drunken driver is usually referred to as one with 0．10-blood alcohol content or roughly three beers, glasses of wines or shots of whisky drunk within two hours．Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts, but the drunken killing has recently caused so many well-publicized tragedies, especially concerning young children, that public opinion is no longer tolerant．
Twenty states have raised the legal drinking age to 21, reversing a trend （逆转潮流） in the 1960s to reduce it to 18．After New Jersey lowered it to 18, the number of people killed by 18-20-year-old drivers more than doubled, so the state recently upped it back to 21．
Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop "responsible attitudes" about drinking and teach them to resist peer pressure to drink．
Some states are punishing bars for serving customers too many drinks．A bar in Massachusetts was fined for serving six or more double brandies to a customer who was "obviously drunk" and later drove off the land, killing a nine-year-old boy．
As the accidents continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years national prohibition （禁令） of alcohol that began in 1919, which President Hoover called the "noble experiment"．They forget that legal prohibition didn't stop drinking, but encouraged political corruption （腐败） and organized crime．As with the booming drug trade generally, there is no easy solution．

A．It may cause organized crime．
B．The new laws can stop heavy drinking．
C．There should be no bars to serve drinks．
D．It is difficult to solve the problem．
Drunken driving—sometimes called America’s socially accepted form of murder—has become a national epidemic（流行病）. Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past ten years. A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beer glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts, but the drunken killing has recently caused so many well-publicized tragedies, especially concerning young children, that public opinion is no longer so tolerant（忍受）.
Twenty states have raised the legal drinking age to 21, reversing a trend（逆转潮流）in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18—20-year-old drivers more than doubled, so the state recently upped it back to 21.
Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop “responsible attitudes” about drinking and teach them to resist peer pressure to drink.
Though new laws have led to increased arrests and tests in many areas already, to a marked drop in accidents, some states are also punishing bars for serving customers too many drinks. A bar in Massachusetts was fined for serving six or more double brandies to a customer who was “obviously drunk” and later drove off the road, killing a nine-year-old boy.
As the accidents continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years national prohibition（禁令）of alcohol that began in 1919, which President Hoover called the “noble experiment”. They forgot that legal prohibition didn’t stop drinking, but encouraged political corruption（腐败）and organized crime. As with the booming drug trade generally, there is no easy solution.
