Global reading
1. Text Analysis: Main Idea and Devices for Developing It
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.

Devices for developing it:
Listing(列举法):
In the main part (the third part) of the passage, the author lists as many as 6 puzzles on the issue of cloning.
Why would anyone want to clone a human being in the first place? (Para. 4)
Will it be possible to clone the dead? (Para. 6)
Would a cloned human be identical to the original? (Para. 8)
What if parents decided to clone a child in order to harvest organs?(Para. 11) How would a human clone refer to the donor of its DNA? (Para. 14)
What are the other implications of cloning for society? (Para. 17)

Discussion(讨论法): The author deals with the 6 common puzzles by offering different opinions from different experts through the device of discussion.

Puzzle 1: Why would anyone want to clone a human being in the first place? (Para. 4)
Discussion: Most experts consider the human cloning falls into two broad categories: 1) parents clone a child to provide transplants for a dying child or to replace that child, and 2) adults might want to clone themselves. (Para. 5)

Puzzle 2: Will it be possible to clone the dead? (Para. 6)
Discussion: Perhaps, if the body is fresh, says one expert. The cloning method used by Wilmut’s lab requires combining an egg cell with the nucleus of a cell containing the DNA of the person to be cloned. And that means that the nucleus must be intact. Cells die and the cell nucleus begins to break apart after death. But, yes, in theory at least it might be possible. (Para. 7)

Puzzle 3: Would a cloned human be identical to the original? (Para. 8)
Discussion: Most of the physical differences between originals and copies are so minor that detection of them would require a sophisticated laboratory. The only possible exception is bearing children. Wilmut and his coworkers are not sure that Dolly will be able to have lambs.They will try to find out once she’s old enough to breed. (Para. 10)

Puzzle 4a: What if parents decided to clone a child in order to harvest organs? (Para. 11)
Discussion: Most experts agree that it would be psychologically harmful if a child sensed he had been brought into the world simply as an organ donor. But some parents already produce second children with nonfatal transplants in mind, and many experts do not oppose this. Cloning would increase the chances for a tissue match from 25 percent to nearly 100 percent. (Para. 12)
Puzzle 4b: What if cloned animals could be used as organ donors? (Para. 13)
Discussion: …But the human body attacks and destroys tissue from other species. To get around that, one company is trying to alter the pig’s genetic code to prevent pig organs from being attacked. If the company’s technicians succeed, it may be more efficient to produce such pigs by cloning than by current methods. (Para. 13)

Puzzle 5: How would a human clone refer to the donor of its DNA? (Para. 14)
Discussion: …Judith Martin, in her writings under the name of “Miss Manners”, suggests the phrase, “Most honored sir or madam”. Why? “One should always respect one’s ancestors,” she says, “regardless of what they did to bring one into the world.”…The editorial director of one dictionary says that the noun “clonee” may sound like a good term, but it’s not clear enough. Instead, he prefers “original” and “copy”. (Paras. 15-16)

Puzzle 6: What are the other implications of cloning for society? (Para. 17)
Discussion: …Specifically, some experts are concerned about the creation of a new (and disrespected) social class: “the clones”. One expert believes the situation could be comparable to what occurred in the 16th century, when Europeans puzzled over how to classify the unfamiliar inhabitants of the Americas, and endlessly debated whether or not they were humans. (Para. 18)

2. Structure Analysis
Part I (Para. 1): With the success of cloning an adult mammal, the world was suddenly brought into the reality of human cloning.
Devices for developing it: Induction (归纳法) (Para. 1)
Specific statements: S.1-5 of Para. 1 + Conclusion: S. 6 of Para. 1
Part II (Paras. 2-3): This part is about the world’s strong and immediate responses in the wake of Wilmut’s announcement.
Devices for developing it:
Exemplification (举例法) Para. 2 Comparison (比较法) Para. 3
Part III (Paras. 4-18): 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.
Devices for developing it:
Classification (分类法), Comparison (比较法), Argumentation (议论法).
Part IV (Para. 19): 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.
Devices for developing it: Reiteration(重申法)

Unit 8 Section B
Who will take advantage of cloning

Teaching objectives:
1. to learn the reading skill;
2. to learn various attitudes toward and the use of cloning technology
3. to learn some words and phrases

Reading Skills: Identifying the Writer’s Purpose (II)
Do exercise XV on P. 235
When you read Passage B, scan it for clues that help you identify the writer’s aim. Use the questions below to guide your scanning, then decide: Is the text informational, persuasive or meant mainly to entertain?
1. The title is actually a question. By using a question as a title, the author tries his best to attract the readers’ attention. Obviously, it’s about the possibility or even legality of human cloning. The author gives us a thorough analysis as to who will take advantage of human cloning.
2. The language is formal and serious. Besides, it is emotional. The evidence for this is the repeated employment of rhetorical questions.
3. Altogether, there are seven questions, including the one in the title. Of the seven, four are rhetorical questions. They appear respectively at the end of Paragraph 2, Paragraph 3, Paragraph 4, and at the beginning of Paragraph 6.
4. Rhetorical questions are mainly intended to stir up the listeners’ or readers’ emotions, to put them off guard, making them ready to accept the speaker’s or writer’s opinion. Rhetorically, this is called emotional appeal. By using rhetorical questions four times, the author of this text is appealing to the readers to accept her idea “Don’t just say no to human cloning”. With all the above in view, we can see that the text is persuasive.
