What is cloning ?
There are different types of cloning, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism. The three types of cloning technologies are: (1) recombinant DNA technology or DNA cloning(基因重组克隆技术), (2) reproductive cloning(再生克隆技术), and (3) therapeutic cloning(干细胞疗法克隆技术).

Celebrity Sheep Dolly (1)

Dolly, the first mammal to be cloned from adult DNA, was put down by lethal injection on Feb. 14, 2003. Prior to her death, Dolly had been suffering from lung cancer and crippling arthritis.

Celebrity Sheep Dolly (2)
Although most Finn Dorset sheep live to be 11 to 12 years of age, postmortem examination of Dolly seemed to indicate that, other than her cancer and arthritis, she appeared to be quite normal. The unnamed sheep from which Dolly was cloned had died several years prior to her creation. Dolly was a mother to six lambs, bred the old-fashioned way.

What animals have been cloned? (1)
Scientists have been cloning animals for many years. In 1952, the first animal, a tadpole, was cloned. Before the creation of Dolly, the first mammal cloned from the cell of an adult animal, clones were created from embryonic cells. Since Dolly, researchers have cloned a number of large and small animals including sheep, goats, cows, mice, pigs, cats, rabbits, and a gaur. All these clones were created using nuclear transfer technology(细胞核移植技术).

What animals have been cloned? (2)

Dolly First cloned mule

Cloned monkeys

First cloned horse

First cloned cat

Cloned twin goats

What are the risks of cloning? (1)
Reproductive cloning is expensive and highly inefficient. More than 90% of cloning attempts fail to produce viable offspring. More than 100 nuclear transfer procedures could be required to produce one viable clone. In addition to low success rates, cloned animals tend to have more compromised immune function and higher rates of infection, tumor growth, and other disorders.

What are the risks of cloning?(2)
Japanese studies have shown that cloned mice live in poor health and die early. About a third of the cloned calves born alive have died young, and many of them were abnormally large. Many cloned animals have not lived long enough to generate good data about how clones age. Appearing healthy at a young age unfortunately is not a good indicator of long term survival. Clones have been known to die mysteriously.

Group Discussions (1)
1. As far as you know, what are the advantages and disadvantages that cloning brings to us?

Some fatal diseases can be cured with the application of cloning; the rate of success in organ transplant will be greatly improved; and the infertile couples are hopeful to have their own babies, etc. However, it may bring confusion and fear to us; it will threaten human society and dignity; and those clones may feel miserable if they are treated as organ donors instead of independent human beings.

Group Discussions (2)
2. Should Humans be cloned? Due to the inefficiency of animal cloning and the lack of understanding about this technology, I’m strongly against it. Not only do most attempts to clone mammals fail, several cloned animals have died prematurely from infections. Moreover, we don’t know how cloning could impact mental development, which is crucial for the development of healthy humans. With so many unknowns concerning reproductive cloning, the attempt to clone humans at this time is considered potentially dangerous and ethically irresponsible.

Comprehension of the Text (1)
1. How did the world react to the first successfully cloned sheep?

The world was amazed by the news at first, then worried about and puzzled over a long list of wild possibilities.

Comprehension of the Text (2)
2. What are the two broad categories human cloning situations often fall into? One of the situations is that parents want to clone a child who can serve either as a transplant donor or as a substitute for the original. The second is that adults want to clone themselves for a variety of reasons.

Comprehension of the Text (3)
3. According to the author, why are twins more alike than clones? Because clones are only physically identical while twins share the same environment within the mother and are usually raised in the same family.

Comprehension of the Text (4)
4. Biologically speaking, what is the only possible major difference between a clone and the original? The only possible major difference is bearing children, as scientists are not sure if Dolly will be able to have lambs.

Comprehension of the Text (5)
5. Why do some parents want to save their fatally ill child through cloning?
Because cloning would increase the chances for a tissue match from 25 percent to nearly 100 percent. 6. Could cloned animals be used as organ donors? If technology was improved, this could be realized.

Comprehension of the Text (6)
7. How did Judith Martin suggest referring to one’s DNA donors?
It might be proper to refer to them as “Most honored sir or madam”. 8. What is the gravest concern about human cloning for society? The creation of a new and disrespected social class: the clones.

Text Analysis (1)
Main idea of the text When a world with human clones was suddenly within reach, people’s reactions to it were strong and varied. They puzzled over a number of questions about the legal and moral implications that had arisen from cloning.

Text Analysis (2)
Main Ideas of Each Part
Part I (Para. 1)

With the success of cloning an adult mammal, the world was suddenly brought into the reality of human cloning. This part is about the world’s strong and immediate responses in the wake of Wilmut’s announcement. This part offers complete or partial answers, from the up-to-date knowledge, to the six questions on the legal and moral implications of cloning. This part is intended to reaffirm the author’s opinion that, although the list of questions could go on, people are just beginning to wonder about the future of the world after cloning.

Part II (Paras. 2-3)

Part III (Paras. 4-18)

Dear Mr. Ng, It is a pleasure to write this letter because it gives me an opportunity to tell you how much I enjoyed your hospitality last weekend. It was my first visit to an American family and, at first, I was very anxious about my limited English and my knowledge of American customs. Then I saw you and your children waiting for me at the station with warm smiles of welcome and your wonderful family put me at ease right away.

Reference Model
There are many happy memories of the weekend that I will keep with me forever. I will remember that you made me feel at home. There were so many new and different things for me to see and do. I particularly enjoyed driving through the countryside and seeing the charming colors of the leaves on the trees. I liked playing baseball with your lovely son and daughter, Chain and Linda. They were patient with me and full of fun. Tell them I will teach them how to play soccer next time.

Reference Model
I also had a good time at the community square dance on Saturday night. It was my first square dance, and I cannot forget how friendly and kind everyone around was. I am back at school now and I am very happy because I know now a real American family and it is one of the nicest families I have ever met. Because my English is still not very good, I cannot express my feelings better. I can only say "thank you" and hope that someday you will visit my country and I can return your hospitality.
Sincerely yours, Wendy Wu
