He isan identical geneticcopy of his brother, achampion racing mulecalled Taz, and thefirst clone to be bornin the equine family.MENUCc•The world's first clonedkitten, named Cc. It wascreated by scientists inTexas using a cell takenfrom an adult tortoiseshellfemale (see next picture).The photo, taken onDecember 22 2001 whenthe kitten was sevenweeks old, was madepublic in February 2002.MENUNoel, Angel, Star, Joy, Mary •Five cloned piglets,born in Virginia, USAon March 5 2000.

They were born exactly two years after Dolly, the British sheep that made history by becoming the first clone of an adult animal. They are the second adult-animal clones, and were produced by a similar technique. A spokesman for the Ishikawa prefectural livestock research centre said the new technique would be used to breed better cattle strains with higher-quality beef or greater milk capacity.MENU ANDi•ANDi (inserted DNA spelled backwards), the first genetically modified rhesus monkey, at the Oregon regional primate research centre in Oregon, USA. The birth of ANDi, the first rhesus monkey cloned by embryo splitting, is another incremental step toward designing and perfecting new treatments for human genetic disorders.The Process of CloningMENUMENUThe Process of Human CloningMENUMENULegal and Moral Implications of Cloning Legal and Moral Implicationsof CloningDiscussionWhat are the pros and cons of cloning?MENUReferencesPROS:•Produce animals with desirable traits.•Increase the efficiency of the livestock production. •Offset losses of among endangered species populations. •Enable better research for finding cures to many diseases.•Provide children for parents who would like a child but can't have one for various reasons.•Provide parents with an opportunity to clone a child who has died.MENUCONS:•Decline in genetic diversity.•Taking nature into our own hands. •Religious and moral reasons. •Physical problems, such as birth defects. •Possibility of mental and emotional problems of the clone.MENUThere are some movies about cloning.•第六日•导演：罗杰·斯波蒂伍德•主演：托尼·戈德温迈克尔·鲁克阿诺·施瓦辛格•《逃出克隆岛》•主演：伊万·麦克格雷格斯嘉丽·约翰逊杰曼·翰苏肖恩·宾迈克·克拉克·邓肯史蒂夫·布西密MENU天赐灵婴【导演】尼克.海姆【主演】格雷格.金内尔, 蕾贝卡•《月球》《银翼杀手》《机械公敌》•《别让我走》《重生校园》MENULegal and Moral Implicationsof CloningMENU NHCE-BIII-Unit 8 IV: Section A--Text 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 justbeginning to wonder about the future of the world after cloning.With the success of cloning an adult mammal, the world was suddenly brought into the reality of human cloning.1. Structure of TextPara.1Para. 2-3Para. 4-18Para.19MENUReference Words:1)The first cloned mammal.2)Cloned human is within reach.3)Science fiction is coming true.2. Questions to Comprehension1)what’s the meaning of Dolly’s success? (para.1)MENUReference Words:2) Why would anyone want to clone a human being in the first place? (para5.)1)parents who want to clone a child, either to providetransplants for a dying child or to replace that child.2)adults who for a variety of reasons might want toclone themselves.MENUReference Words:Perhaps, if the body is fresh . because the nucleus must be intact .3) Will it be possible to clone the dead?(para.7)MENUReference Words:Identical genes don't produce identical people. interms of biology ,a clone would not be identical to the "master copy". 4) Would a cloned human be identical to the original?(para.9,10)MENUReference Words:yes, some people are tryingto do it.5) Could cloned animals be used as organ donors? (para.13)MENUReference Words:It would be psychologically harmful if a child sensed he had been brought into theworld simply as an organ donor.6)What if parents decided to clone a child in order to harvest organs? (para.12)MENUReference Words:Not mother and father , some people suggests "Miss Manners“ or "original" and "copy".7) How would a human clone refer to the donor of its DNA? (para.15,16)MENUReference Words:some experts are concerned about thecreation of a new (and disrespected) social class: "the clones".8) What are the other implications of cloning for society? (para.18)。
