A private group of scientists has announced plans to make an exact copy of a human being. An American member of the team says he and the others will soon begin a serious effort to clone humans. Panos Zavos says the team hopes to manufacture the world’s first cloned baby within the next two years.
In recent years, scientists have produced exact genetic copies of sheep and a few other animals. They created these clones from a single cell of an adult animal.
Three years ago, another American doctor, Richard Seed, announced plans to clone a human being. However, there is no evidence that he has been successful.
Doctor Zavos says the new international group plans to offer human cloning only to women who are currently not able to become pregnant or produce children. He says the aim is to assist people who want to have their own biological child.
The technology would be similar to that used to clone animals. It would involve cleaning genetic material from a woman’s egg. Doctors then would place genetic material from the woman’s husband into the egg before putting it into the woman’s uterus(子宫).
Doctor Zavos says his group plans to do the work in a country near the Mediterranean Sea. He did not name the country. He says an Italian reproductive expert, Sevorino Antinori, is leading the team. Doctor Antinori has led the efforts to help many older women become pregnant. He is known for establishing pregnancies in women as old as sixty.
Many medical experts and other groups are opposed to the idea of cloning humans. Several countries ban or restrict work on human cloning. Several doctors criticize the announcement by Doctor Zavos. They say doctors do not know if cloning humans is possible or safe. They say it would be irresponsible to attempt to clone a human being. That is because the chances of success are too small and the risks are too great.

Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman’s shoe of a style popular in the 1890s. But what is unique(独特的) about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outface? Or did she throw away goods that she didn’t need in order to travel lighter?
Over 100, 000 people with “gold fever” made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildness. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.
The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks(背包) each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century.
1. The ordinary woman’s leather shoe is considered unusual because _______.
A. it was an important clue to life in the past B. it was found on a famous trail
C. it at one time belonged to a VIP D. it was a fashionable shoe at that time
2. According to this passage, many people who went to Alaska _______.
A. eventually became millionaires B. brought with them many shoes
C. had conflicts with the Eskimos D. were not properly equipped
3. The Canadian government made gold seekers bring one year’s supplies with them so that _______.
A. they would not die of hunger and cold
B. the army would have enough food for fighting a war
C. they would change these goods with the Eskimos
D. the supplies would make Alaska rich
4. No matter what happened to the woman who owned the shoe, _______.
A. she must have lived a happy life
B. she certainly dropped the shoe on purpose
C. her adventurous spirit is definitely admired
D. her other shoes were equally fashionable
(B)
Listen carefully, working people, we would like to tell you something that could save your precious time and money! Best of all, it is free!
It’s “no”.
What do you ask? We’ll say it again: “No”.
Sweet and simple “no”.
Say “no” at your office and see how quickly that pile of work on your desk disappears.
“Saying ‘no’ to others means you are saying ‘yes’ to yourself, ” said Leslie Charles, a professional speaker from East Lansing, Michigan.
“Time is precious. People are spending money buying time. And yet we are willing to give up our time because we can’t say ‘no’.”
Susie Watson, a famous writer, said people who always say “yes” need to say “no” without guilt(内疚)or fear of punishment. “I would rather have someone give me a loving ‘no’ than an obligated(强制的) ‘yes’, ” she said.
Susie Watson says she feels “no” obligation to give an explanation when she says “no” either socially or professionally. Does she feel guilty about it? “Not at all, ” said Watson, who is director of advertising and public relations at Timex Corp in Middlebury, Conneticut. “Most people are afraid of saying ‘no’… My advice is to say ‘yes’ only if you don’t mean ‘no’.”
Watson said “no” is the most effective weapon against wasting time. “Every year there are more demands on your time… Other people are happy to use up your time, ” Watson said. Time saving appears to be “no’s” greatest friend.
“No” can be your new friend, a powerful tool to take back your life. “No” may even take you further in the business world than “yes”.
“No” is power and strength. “No” now seems completely correct. “Saying ‘no’ isn’t easy. But finally it’s greatly liberating,” Charles said. But, he added, a “no” project needs to be worked on every day because it is hard to change long-term habit.
But, he also warns: “Don’t go to extremes. Don’t find yourself saying ‘no’ to everything. In return you should learn to hear ‘no’.”
5. The sentence “Saying ‘yes’ to yourself” means _______.
A. you can have more time to play with others
B. you needn’t care about other’s feeling if you are happy
C. you are selfish and treat others rudely
D. you can deal with your business as you have planned
6. When you say “no” to others you should say it in a _______.
A. secret way B. polite way
C. proud way D. guilty way
7. In Watson’s opinion, people can save much time on condition that _______.
A. they say “no” at a suitable time
B. they say “no” as much as possible
C. they are afraid of saying “no”
D. they make others angry at them
8. If a person says “no” to everything, the result he or she receive may be that he or she _______.
A. enjoys a wonderful life B. makes a lot of money
C. faces difficulty in life D. forgets to say “yes” in the end
(C)
A characteristic of American culture that has become almost a tradition is to respect the self-made man — the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.
This attitude toward manual(体力的) labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously (豪华地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional man may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.
9. From paragraph 1, we can know that in America _________.
A. people tend to have a high opinion of the self-made man
B. people can always rise to the top through their won efforts
C. college professors win great respect from common workers
D. people feel painful to mention their fathers as labors.
10. According to the passage, the hostess cooks dinner herself mainly because _________.
A. servants in American are hard to get
B. she takes pride in what she can do herself
C. she can hardly afford servants
D. It is easy to prepare a meal with canned food
11. The expression “ wait on table” in the second paragraph means “_________”.
A. work in a furniture shop B. keep accounts for a bar
C. wait to lay the table D. serve customers in a restaurant
12. Which of the following may serve as the best title of the passage?
A. A Respectable Self-made Family B. American Attitude toward Manual Labor
C. Characteristics of American Culture D. The Development of Manual Labor

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物种). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
17. The aim of “Noah’s Ark” project is to _______.
A. make efforts to clone the endangered pandas
B. save endangered animals from dying out
C. collect DNA of endangered animals to study
D. transfer the nuclear of one animal to another
18. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
A. available panda eggs B. host animals
C. qualified researchers D. enough money
19. The best title for the passage may be _______.
A. China’s Success in Pandas Cloning
B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas
D. China —the Native Place of Pandas Forever
20. From the passage we know that _______.
A. Kraemer and his team have succeeded in cloning a dog
B. scientists try to implant a panda’s egg into a rabbit
C. Kraemer will work with Chinese scientists in clone researches
D. about two thousand of species will probably die out in a century
查看习题详情和答案>>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 discussed 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 these two diseases can 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 span(寿命) can be prolonged. www.zxxk.com
Gene technology can help people to give birth to 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 about hereditary diseases. But gene technology can solve this problem perfectly. The scientist 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 manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the government 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. The two diseases of cancer and heart disease.
D. Hereditary diseases and cancer.
2.What’s the main idea of the third paragraph?
A. How gene technology can be applied in the field of treating hereditary diseases.
B. Gene technology can be used to clone human babies.
C. Gene technology can help people to give birth to a baby.
D. Gene technology can help the English imperial family out.
3.In what way gene technology can help to treat hereditary diseases?
A. Using gene technology, people with hereditary diseases can have more living days.
B. Using gene technology, the scientist finds the wrong gene and corrects it.
C. Using gene technology, human babies can be cloned.
D. Doctors can cure cancer and heart disease with the help of gene technology.
4.What is the main purpose of writing this passage?
A. Expressing the writer’s idea that gene technology will benefit people.
B. Telling people the disadvantages of gene technology.
C. Telling the readers that gene technology will not benefit people.
D. Explaining that gene technology will also do harm to the humanity.
