Science and technology have advanced at such a rate that cloning has now become a reality. The possibility of cloning humans is a serious issue(争论点) and raises ethical(伦理的) questions. In my opinion, cloning is useful for research into cures for disease. However, I think that it needs to be approached with caution and carefully monitored by governments.
Research into cloning and stem(严格的) cell production is primarily aimed at finding new treatments for currently incurable illnesses. While this would improve the quality of life for many, not enough is understood about what effects cloning would have on the world in the future. This is primarily because we do not understand enough about the results of cloning and both the physical and psychological effects that it is likely to have on cloned humans and on the rest of the world. Furthermore, it is thought that a cloned human would be unlikely to survive birth and would suffer from complications(并发症) resulting from malformed(畸形) organs .
There are also serious ethical issues in danger. In essence(在本质上), those who are against cloning would argue that scientists have no right to play God and to interfere(干扰)with natural processes. Producing embryos for the purpose of harvesting stem cells for research presents important questions about the nature and status of the embryo being produced. It may also make us question whether throwing it away after use reduces the value we place on human life.
In conclusion, I do not agree that research into cloning using human embryos should continue. This is not only because it may reduce the value we place on human life, but also because not enough is known about the effects. However, I do think that if there is a way to produce stem cells using cloning which does not put human life at risk, then governments should continue to support it.
1.What is the writer’s general opinion on cloning?
A. It is useful in every area of research.
B. It needs to be carefully controlled by governments.
C. It is useful for research into cures for disease if it is controlled.
D. It is only useful for research into cures for disease.
2.The underlined word “approach” in the first paragraph means “______”
A. reach a high level or amount B. move forward
C. come near D. deal with
3.The writer’s main reason against cloning is that ______.
A. not enough is known about the effects of cloning
B. a cloned human would be likely to die of malformed organs
C. cloning has negative physical and psychological effects on clones
D. it would affect the quality of life for many
4.In the last paragraph, the writer thinks governments should______
A. not put human life at risk
B. support all forms of research into stern cell production
C. not support any form of research into stern cell production
D. support research into stern cell production harmless to humans life

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic talked about by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only can these two diseases be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life can be longer.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary (遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing with hereditary diseases. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to make human beings in large quantities. In the past few years, scientists have succeeded in cloning babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
1.What does “these two killers” in the second paragraph refer to?
A. Gene technology and another treatment of the two diseases.
B. The two murderers who killed the cloned baby.
C. Hereditary disease and cancer.
D. Cancer and heart disease.
2.In what way can gene technology help to treat hereditary diseases?
A. Using gene technology, a scientist finds the wrong gene and corrects it.
B. Using gene technology, people with hereditary diseases can live longer.
C. Using gene technology, human babies can also be cloned.
D. Doctors can cure cancer and heart disease with the help of gene technology.
3.What is the main purpose of writing the text?
A. Explaining that gene technology will also do great harm to human race.
B. Telling the readers the positive effects gene technology has on people’s life.
C. Expressing the writer’s idea that gene technology will benefit people.
D. Informing people that gene technology helps clone babies in large quantities.

Remembering names is an important social skill．Here are some ways to master it．
Recite and repeat in conversation．
When you hear a person's name，repeat it．Immediately say it to yourself several times without moving your lips．You could also repeat the name in a way that does not sound forced or artificial．
Ask the other person to recite and repeat．
You can let other people help you remember their names．After you've been introduced to someone，ask that person to spell the name and pronounce it correctly for you．Most people will be pleased by the effort you're making to learn their names．
Admit you don't know．
Admitting that you can't remember someone's name can actually make people relaxed．Most of them will feel sympathy if you say，"I'm working to remember names better．Yours is right on the tip of my tongue．What is it again？"
Use associations．
Link each person you meet with one thing you find interesting or unusual．For example，you could make a mental note："Vicki Cheng…tall，black hair．"To reinforce（加强） your associations，write them on a small card as soon as possible．
Limit the number of new names you learn at one time．
When meeting a group of people，concentrate on remembering just two or three names．Free yourself from remembering everyone．Few of the people in mass introductions expect you to remember their names．Another way is to limit yourself to learning just first names．Last names can come later．
Go early．
Consider going early to conferences，parties and classes．Sometimes just a few people show up on time．That's fewer names for you to remember．And as more people arrive，you can hear them being introduced to others-an automatic review for you．
1.If you can't remember someone's name，you may ______ ．
A. tell him the truth B. tell him a white lie
C. ask him for pity D. ask others to help you
2.When you meet a group of people，it is better to remember ______ ．
A. all their names B. a couple of names first
C. just their last names D. as many names as possible
3.What does the text mainly tell us？ ______
A. Tips on an important social skill．
