【文章內容簡介】 their first in appearance, but all the evidence suggests the two would have very different personalities. Twins separated at birth do sometimes share personality characteristics, but such characteristics in a cloned son or daughter would only be reminders of the child who was lost. 課文閱讀 隨 筆 課文縮寫 結構分析 Text Analyzing and Reading Back 預習 小結 導入 寫作 Para. 10a Even in terms of biology, a clone would not be identical to the ―master copy‖. The clone’s cells, for example, would have energyprocessing machinery that came from the egg, not from the person who was cloned. But most of the physical differences between originals and copies are so minor that detection of them would require a sophisticated laboratory. The one possible exception is bearing children. 課文閱讀 隨 筆 課文縮寫 結構分析 Text Analyzing and Reading Para. 10b The scientists responsible for the successful cloning 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 11 What if parents decided to clone a child in order to harvest organs?

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.

Pigs, for example, have organs similar in size to humans’. But the human body attacks and destroys tissue from other species. To get around that, one pany is trying to alter the pig’s geic code to prevent pig organs from being attacked. If the pany’s technicians succeed, it may be more efficient to produce such pigs by cloning than by current methods.

Para. 15a ―Mom‖ is not right, because the woman who supplied the egg and gave birth to the infant would more appropriately be called Mother. ―Dad‖ isn’t right, either. A traditional father supplies only half the DNA in a child.

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‖.

Specifically, some experts are concerned about the creation of a new (and disrespected) social class: ―the clones‖.

With Dolly brought into the world, a world with human clones was suddenly within reach. In the wake of that news, therefore, governments hurried to draft guidelines for the unknown, a future filled with incredible possibilities.
