It might be proper to refer to them as “Most honored sir or madam”. The creation of a new and disrespected social class: the clones. 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.

This part is about the world’s strong and immediate responses in the wake of Wilmut’s announcement. This part offers plete or partial answers, from the uptodate 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. implication prohibit mount resemble minor fatal deliberate classify word that…/of… succeed in doing draft guidelines for fall into in theory be identical to/with in terms of be concerned about be parable/similar to Words and Expressions Structures 1.

The three types of cloning technologies are: (1) rebinant DNA technology or DNA cloning（ 基因重組克隆技術(shù)） , (2) reproductive cloning（ 再生克隆技術(shù)） , and (3) therapeutic cloning（ 干細(xì)胞療法克隆技術(shù)） . What is cloning ? Dolly, the first mammal to be cloned from adult DNA, was put down by lethal injection on Feb. 14, 2023. Prior to her death, Dolly had been suffering from lung cancer and crippling arthritis. Celebrity Sheep Dolly (1) 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 Celebrity Sheep Dolly (2) prior to her creation. Dolly was a mother to six lambs, bred the oldfashioned way. 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（ 細(xì)胞核移植技術(shù)） . What animals have been cloned? (1) Dolly Cloned monkeys First cloned mule What animals have been cloned? (2) Cloned twin goats First cloned horse First cloned cat 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 promised immune function and higher rates of infection, tumor growth, and other disorders. What are the risks of cloning? (1) 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. What are the risks of cloning?(2) 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 an transplant will be greatly improved。 it will threaten human society and dignity。t believe me. 他微微一笑 ,但這一笑暗示著他不相信我的話。 prohibit vt. fobid, esp. by law or rule。 make impossible 禁止，使不可能，阻止 Smoking is strictly prohibited in the process of handling explosive materials. 在處理易爆物時(shí) , 嚴(yán)格禁止吸煙。 mount vi./vt.
