In the past, scientists have produced exact genetic copies of sheep and a few other animals. They 1 these clones from a single cell of an adult animal.
Recently, a private group of scientists has announced 2 to make an exact copy of a human being. Doctor Zavos, an American member of the team, says he and 3 will soon begin to clone humans and they hope to produce the world’s forst cloned 4 within the next two years.
Doctor Zavos says the new 5 group plans to offer human cloning to women unable to become 6 and produce children. The 7 would be similar to that used to clone animals. It would 8 clearing genetic material from a woman’s egg. Doctors then would 9 genetic material from the woman’s husband into the egg 10 putting it in the women’s uterus(子宫).
Doctor Zavos says his 11 plans to do its work in a country near the Mediterranean Sea, but he did not 12 the country. He days an Italian reproductive expert, Severino Antinori, is 13 the team. Doctor Antinori has made 14 efforts to help many older women become pregnant. He is known for 15 pregnancies in women as old as sixty.
Many medical experts and other groups 16 the idea of cloning humans. Several doctors criticized the 17 by Doctor Zavos. They say doctors do not know if cloning humans is 18 or safe.

They invited all the most famous experts in this field to discuss and quite a few suggestions were 4 (put) forward. Some of the top experts picked out those suggestions and tested them to see whether they were 5 (avail). Doctor Zhong chose one patient who was seriously ill and had little hope of picking 6 and had the new medicine 7 (test) on him. To his great joy, this patient recovered! He made his way 8 his office and telephoned to the top official, 9 (tell) him this exciting news. For convenience, he moved to live in his office. His method 10 make sense.

A
Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That’s nothing more than a fiction.
But could we really
clone endangered animals?
To date, the
most successful attempt to do so was the cloning of a gaur, a rare ox-like
animal from southeast Asia. Scientists used a cow to bring the cloned baby
gaur, named Noah. Two days after birth, however, Noah died from a common
bacterial infection. Other endangered species that may be cloned include the
African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.
Next, could we really clone extinct animals?
In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother.
In reality? Probably
not. On the one hand, it’s not likely that extinct animals’ DNA could survive
undamaged for such a long time. Cloning extinct animals as wool mammoth,
Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly
well-preserved DNA. On the other hand, for example, a gaur can have a cow as a
surrogate mother, definitely not a monkey. But what about an extinct animals as
unique as the panda? What species could possibly serve as a surrogate mother?
Cloning presents
many exciting possibilities. However, even if extinct animals are brought back,
they could not survive in today’s world. Not only do most extinct animals have
no habitat to love in, but the other plants and animals they depended on for
food may also be gone as well.
1. It can be learned from the text that ________.
A. scientists have cloned the African bongo antelope
B. both the cheetah and the giant panda live in Asia
C. the gaur lives in Asia and is endangered
D. the gaur is an extinct species
2. The underlined words “a surrogate mother” probably refer to a female who ______.
A. contributes its eggs to another female B. gives birth to a baby for another female
C. gives birth to a baby of its own D. cannot give birth to a baby
3. The difficulty in cloning an extinct species is the lack of ______.
A. both the well-preserved DNA and plants to live on
B. both the habitat to live in and the well-preserved DNA
C. both habitat to live in and plants to live on
D. both the well-preserved DNA and a surrogate mother
4. In the author’s opinion, it is possible that ______.
A. some extinct species may be cloned, but not survive
B. extinct species may be cloned and easily survive
C. a gaur can have a monkey as a surrogate mother
D. all the extinct species may be cloned
B
Research advances over the past decade have told us that, with a little work, we humans can clone just about anything we want, from frogs to monkeys and probably even ourselves!
So, we can clone things, but why would we want to?
Of
all the reasons, cloning for medical purposes most probably benefit large
numbers of people. How might cloning be used in medicine?
1. Cloning animal models of disease
Much of what researchers learn about human disease comes from studying animal models such as mice. Often, animal models are genetically engineered to carry disease-causing mutations (变异) in their genes. Creating these transgenic(转基因的) animals is a process that requires trial-and-erro and several generations of breeding (培育). Cloning technologies might reduce the time needed to make a transgenic animal model, and the result would be a population of genetically identical animals for study.
2. Cloning stem cells (干细胞) for the treatment of diseases
Stem cells are the body’s bulding blocks, responsible for developing and repairing the body throughout life. As a result, they might be used to repair damaged or diseased organs and tissues. Researchers are currently looking up cloning as a way to create certain human stem cells for the treatment of diseases.
3. Cloning farm animals for drug production
Farm animals such cows, sheep and goats are currently being genetically engineered to produce drugs or proteins that are useful in medicine. Just like creating animal models of disease, cloning might be a faster way to produce large numbers of genetically engineered animals.
5. From Purpose One, we can infer that ______.
A. most transgenic animals are cloned
B. most animals carry engineered genes
C. most transgenic animal models are not cloned
D. most animals carry disease-causing mutations in their genes
6. It can be learned from Propose Two that cloning technologies can be mainly used to _____.
A. create damaged or diseased organs and tissues
B. clone genetically defined human stem cells
C. develop and maintain the body D. repair the body throughout life
7. According to Purpose Three, cloning technologies can be mainly used to ______.
A. speed up the producing of genetically engineered animals
B. produce drugs or proteins that are useful in medicine
C. raise genetically engineered cows, sheep and goats
D. produce large herds of animals for human beings
C
Difficult times often bring out the best in people. And this was the case for basketball star Yao Ming, who hosted a television show in Shanghai that raised US$300,000 to help researchers find a cure for SARS. Fundraising, or charity, is an act of goodwill towards others. Charities in the West have more flexible ways. Look at a typical day for Ruth, a wealthy woman in the UK, for example. Ruth wakes up in the morning and collects her post. There’s a letter addressed to her with a picture of a half-dead, beaten horse. It’s from a charity asking Ruth to donate money to save the animals. The door bell rings and there, on Ruth’s doorstep, is an old woman asking for money to help the aged. She turns on the television, hears sad music and sees a picture of a wide-eyed child dying of hunger in Africa with an appeal for money to help the child. Ruth then goes shopping for a dress to wear to that evening’s large party for the rich and famous. The ticket cost her a small fortune, but she doesn’t mind because most of the money is going to a charity that fights AIDS. She feels good about going because she’s helping the sick. Within five minutes of walking down the street, Ruth has passed a charity shop. She doesn’t stop because she doesn’t think she’d find a suitable dress there—it’s full of old, secondhand clothes. But, many other people enter and but all sorts of bargains. Edna, a little old lady, looks after the shop. Any profit it has made goes to a cancer charity. Now that she has retired, she has plenty of spare time to offer her services for free.
For people like Yao Ming, Ruth and Edna, charity is a virtue that holds the same importance in life as faith and hope. “As you look back on your life, the moments that stand out are the moments when you have done things for others,” said Scottish author Henry Drummond.
8. Which of the following is NOT mentioned in the story as a way of fundraising?
A. Charity party B. Charity post
C. Charity TV program D. Charity for beggars.
9. What does the word “raise” in the first paragraph mean?
A. Collect together B. Donate
C. Increase D. Bring to someone’s attention.
10. We can infer from the passage that .
A. Yao Ming donated US$300,000 to help researchers find a cure for SARS
B. Edna may not be a rich lady but she is willing to do something for others
C. Ruth leads a busy life and she feels very tired
D. Ruth is angry because so many people ask her for money every day
11. What’s the writer’s attitude towards charity?
A. The writer thinks it’s something only people like Ruth can afford to do
B. The writer just wants to inform us of the different ways to practice charity
C. The writer thinks it’s a virtue and admires the people who practice it
D. The writer doesn’t make it clear in the story
12. The underlined part in the last paragraph probably means that .
A. when you look back sometimes, you need stand out
B. when you want to do something for others, you need stand out
C. the moment you stand out, you can do something for others
D. what impresses people deeply is what they have done for others
D

No smoking, please!
Smoking is not only a bad habit but also bad for the health of smokers themselves and the people who are around them. In fact, many kinds of diseases are caused by smoking, as a result, millions of smokers die from smoking tobacco.
Smoking itself is a waste of money and it costs one so much money. Besides, many fires are often caused by careless smokers.
Young people, don’t join the group of people in hospital, the group of dying people, because they smoke.
