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.

ips with more than a limited number of people. No matter how hard the Internet tries to put you in communication, its best efforts will be defeated by your mind.The problem is twofold（双重的）. First, there is a limit on the number of people we can hold in mind and have a meaningful relationship with. That number is about 150 and is set by the size of our brain. Second, the quality of your relationships depends on the amount of time you invest in then. We invest a lot in a small number of people and then distribute what’s left among as many others as we can. The problem is that if we invest little time in a person, our engagement with that person will decline until eventually it dies into “someone I once knew”.
This is not, of course, to say that the Internet doesn’t serve a socially valuable function. Of course it does. But the question is not that it allows you to increase the size of your social circle to include the rest of the world, but that you can keep your relationships with your existing friends going even though you have to move to the other side of the world.
In one sense, that’s a good thing. But it also has a disadvantage. If you continue to invest in your old friends even though you can no longer see them, then certainly you aren’t using your time to make new friends where you now live. And I suspect that probably isn’t the best use of your time. Meaningful relationships are about being able to communicate with each other, face to face. The Internet will slow down the rate with which relationships end, but it won’t stop that happening eventually.
小题1:The number of friends we can keep relationships with is decided by__________.
| A．the Internet | B．the time we have | C．the place we live | D．the mind |
nd paragraph probably means “__________”.| A．appointment | B．connection | C．interview | D．agreement |
| A．the Internet helps to keep in touch with friends far away |
| B．the Internet determines the quality of social relationships |
C．the Internet greatly increases the size of social circles |
| D．the Internet is of no value in social communication |
| A．To keep in touch with old friends when we have moved away. |
| B．To chat with friends often on the Internet. |
| C．To make more new friends face to face. |
| D．To stop using the Internet to make new friends. |
| A．He thinks it useless | B．He is hopeful of it. |
| C．He approves of it. | D．He doubts it. |
Considering that 15 percent of American children aged 6 to 18 are overweight, supporters say more money and thought must be put into phys ed curriculum. In many cases, that may mean not just replacing the old gym-class model with fitness programs but also starting up phys ed programs because school boards often "put P.E. on the chopping block (砧板), cutting it entirely or decreasing its teachers or the days it is offered," says Alicia Moag-Stahlberg, the executive director of Action for Health Kids. The difference in phys ed programs is partly due to the lack of a national standard. "Physical education needs to be part of the core curriculum," she added.
The wisdom of the new approach has some scientific support. Researchers at the University of Wisconsin have showed how effective the fit-for-life model of gym class can be. They observed how 50 overweight children lost more weight when they cycled and skied cross-country (越野)than when they played sports. The researchers also found that teaching sports like football resulted in less overall movement, partly because some reluctant（不情愿的）students were able to sit on the bench.
Another problem with simply teaching group sports in gym class is that only a small percentage of students continue playing them after graduating from high school. The new method teaches skills that translate to adulthood.
小题1:According to the passage, what is usually taught in the old gym class?
| A．Lift weights | B．Climb a rope | C．Cycle | D．Have a balanced diet |
| A．Schools do not pay enough attention to P. E.. |
| B．Schools welcome P. E. but do not have time for it. |
| C．Schools put P.E. in the first place. |
| D．Schools cut down other subjects’ time for P. E.. |
| A．More teenagers are overweight. |
| B．Traditional group sports teaching is not effective. |
| C．Students need to learn some skills to help them lead a physically active life. |
| D．Phys ed programs need less money to support. |
| A．Two | B．Three | C．Four | D．One |
| A．The Phys ed teaches group sports. |
| B．The Phys ed provides more fitness programs. |
| C．The Phys ed teaches tools and skills which could be used in the future life. |
| D．The Phys ed has more support from the government. |
However, watchmakers optimistically say that watches regain popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality timepiece that doesn"t just keep good time. Fifty years ago, watchmakers boasted(自夸) about their products" accuracy. But in recent years, the watch industry has transformed itself into an accessory(附件，配件) business. And for many today, the image(外形) a watch communicates has become more important than the time it tells.
"Complications" ─ features that go beyond simple timekeeping ─ are an important part of a watch"s image. Today"s watches offer a host of features that suit almost any personality. These features include altitude trackers(追踪器), compasses(指南针), lunar calendars, USB drives, and even devices that measure the effectiveness of golf swings!
Creativity is also a key element in today"s watches. For example, Japanese watchmaker Tokyoflash makes watches that don"t even look like watches. The company"s popular Shinshoku model uses different color lights to tell the time. It looks more like a futuristic bracelet(手镯) than a watch. Another Japanese watchmaker, EleeNo, makes a "handless" watch. Using a ring of circles to keep time, this watch makes an excellent conversation piece.
Whether a watch communicates fashion sense, creative flair or a love of sports, consumers want their timepieces to stand out. Nowadays, everyone has the same kind of gadget in their bags, so people want to make a statement with what"s on their wrists(手腕). Will this interest in wrist fashion last? Only time will tell!
小题1:Why aren’t watches popular with young people as before?
| A．Because watches cannot keep good time as cell phones, mini laptops and MP3 players. |
| B．Because watches are featured by the disadvantages of simple function |
| C．Because watches are too expensive to afford. |
| D．Because watches don’t have beautiful appearance as other modern time telling tools. |
| A．Watching-making is facing a survival crisis challenge. |
| B．Watching-making is faced with the developing opportunity. |
| C．Watching-making becomes the sun rising industry. |
| D．Watching-making has a specific development target. |
| A．people will gradually lose interest in watches as they grow older |
| B．watchmakers hardly change the development strategy for watches |
| C．today’s watches are better than those in the past in quality |
D．customers used t o be more concerned with the quality of a watch than with its image. |
| A．multifunction | B．accuracy | C．nice design | D．low price |
| A．Watches and Teenagers | B．The History of Watches |
| C．The Accuracy of Watches | D．Watches Tell More Than Time |
One theory is that wolves howl to bond better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behaviour.
Indeed, there have been times when wolves have been seen one moment howling in a chorus, and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be “punished” for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status a
mong its members? —Why do wolves howl for sure?What is clear, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering.
Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of “roll call” where wolves all howl together to report their presence.
小题1:What is the possible similarity between wolves’ howling together and humans’ singing in chorus?
| A．The act of calling each other. | B．The sense of accomplishment. |
| C．The act of hunting for something. | D．The sense of belonging to a group. |
| A．Wolves separate from each other after howling. |
B．Wolves tend to protect their huntin g grounds. |
| C．Wolves sometimes have quarrels after howling together. |
| D．Wolves of low rank are encouraged to join in the chorus. |
| A．show their ranks | B．find their companions |
| C．report the missing ones | D．express their loneliness |
| A．howling is a signal for hunting |
| B．howling is a way of communication |
| C．howling often occurs in the morning |
| D．howling spreads from one to another |
The major reason I see for studying history is that we can learn from the past．I am convinced that the world would be a much better place if more people understood the successes and failures of the past and the things that made these successes and failures．However, as the unfortunately true statement goes "the one thing we seem to learn from history is that we don"t seem to learn from history". Perhaps at least in teaching history, to my children I can do a small part in changing this．
A second major reason for studying history is th
at it is hard to understand the current political climate in the absence of an understanding of its historical context．We can’t even understand why we are and where we are without history, much less （更不必说） try to figure out where we are going or how we should get where we want to be．I teach my children history, for one more reason．I purchased a set of historical audio （录音机） tapes for our children．My seven-year-old son listened to them over and over．It was my hope that he would become inspired by the accomplishments of people like the Wright brothers to accomplish things by himsel
f．I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr．if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what he accomplished．I also think that by studying people like Adolph Hitler, people can learn to stand against the things that he stood for．小题1:What message can we get from the underlined sentence in Paragraph 2 ?
| A．Many people aren"t clever enough to learn well from the past． |
| B．Many people fail to make good use of history and make the same mistakes． |
| C．Many people feel it hard to understand history． |
| D．Many people have no interest in studying history． |
| A．It makes the current political situation go smoothly |
| B．It helps us realize the importance of historical events |
| C．It helps us understand why things are the way they are |
| D．It helps people accept the present situation where they live |
| A．People can be inspired to do good, while also learning to fight against evil |
| B．People may also learn from bad historical figures |
| C．More celebrations should be held to honor their achievements |
| D．Today’s people can also achieve what they achieved |
| A．How to teach history effectively． |
| B．Some negative reasons for studying history． |
C．Ho w to get more people to study history． |
| D．Some bad historical figures． |
| A．inspire the parents to teach their children history |
