Module5 Unit3 Science and natureReading The perfect copy Scientists have announced that they have cloned the first human embryo . This has caused much debate round the world .On the one hand , some scientists point out that if you clone an embryo , you can produce valuable human tissues- such as bone or lung tissue- that could be used to save human lives . On the other hand , many people , including some scientists , disagree and are afraid that , if mankind toys with nature in this way , we may be on our way to producing a real-life Frankensteins monster. Cloning is producing an exact copy of a plant or an animal using its cells .The first mammal to be cloned successfully from an adult cell was Dolly the sheep. She was born in 1966 and died in early 2003 , at a much younger age than normal . When she was born , many people were worried that cloning would lead to more diseases in the animal world . However , in general the scientists were praised for their wonderful scientific were praised for their wonderful scientific advance . Lan Wilmut , the Scottish scientist who created Dolly , is shocked that some scientists are now considering cloning human beings . Although he researches cloning , his intention has never been to create copies of humans . Instead , he thinks research efforts should concentrate on creating new tissues and organs that can be used to cure diseases like cancer . However , some people believe that cloning human embryos with the intention of destroying them shows no respect for human life . Even though human cloning is causing a lot of anxiety , it is good news for Faye Wilson , a 41-year-old saleswoman who cannot have a baby . “ I am anxious to have a child of my own,” she says , “ I dont want to adopt someone elses child -if I had the chance, I would have a cloned baby right now .” While cloning human embryos is not legal in many countries , some scientists are already pushing ahead with research in order to produce a cloned human baby . Severino Antinori , an Italian physician , has declared that he wants to be the first to clone a human being . In China , scientists have focused their efforts on cloning animals , as well as cloned tissues to be used in medical treatment .China has succeeded in producing clones of cows and goats , and continues to research ways in which cloning can benefit mankind . Module 5 Unit 3 Reading完美的复制科学家们宣布他们已经克隆出第一个人类胚胎。这引起了世界范围内的很多争论。一方面，一些科学家指出如果克隆人类胚胎，你就可以制造出宝贵的人体组织如骨组织或肺组织它们可以用来拯救人类的生命。另一方面，包括一些科学家在内的许多人持有不同意见，他们担心人类如果如此戏弄自然，我们可能将制造出一个现实生活中的费兰肯斯坦怪物。克隆是用某种植物或动物的细胞制造出一模一样的植物或动物。第一个成功地用成年动物细胞克隆出的哺乳动物是多利羊。她1996年被克隆出来，2003年初死亡，寿命要比普通的羊短很多。当她被克隆出来的时候，许多人担心克隆会导致动物世界中的更多疾病。然而，总体来说，这些科学家还是因为其杰出的科学进展获得人们的赞誉。克隆出多利的苏格兰科学家伊恩威尔莫特对于有些科学家正在考虑克隆人类感到非常震惊。尽管他研究克隆技术，但他的目的从来就不是制造人类的复制品。相反，他认为克隆研究应该注重创造用于治疗的新组织和器官，这些新组织或器官能被用来治疗像癌症这样的疾病。但是，有些人认为怀着摧毁人类胚胎的意图来克隆人类胚胎是对人类生命的不尊重。 尽管克隆人引起了很多不安，但对于不能生育的41岁女销售员费依威尔逊来说却是个好消息。“我渴望有一个我自己的孩子，”她说：“我不想领养别人的孩子如果我有这个机会，我会立即要一个克隆婴儿。”尽管克隆人类胚胎在很多国家还不合法，但一些科学家已经在加紧研究，以制造出克隆的人类婴儿。一位名叫塞维里诺安蒂诺里的意大利医生宣称他想成为第一个克隆人类的人。在中国，科学家们把精力集中在研究克隆动物上，以及用于医疗的克隆组织上。中国已经成功克隆出牛和羊，将继续研究能够造福人类的克隆方式。Dear Editor I believe that human cloning is wrong . If we toy with nature , we will have to deal with the consequences . Who knows what could happen ? Human life would just become a crop to be harvested or a product for sale . The human race is using up the Earths natural wealth. We should be having fewer babies in order to reduce the Earths population , not cloning more. I felt sorry for the lady who cannot have a baby , but I would like to point out that there are many children in the world with no parents who would be delighted to have a mother . Pauline Carter亲爱的编辑：我认为克隆人类是错误的。如果我们戏弄自然，我们就会不得不处理其后果。谁知道会发生什么呢？人类生命将变得像可以收割的庄稼或可供买卖的产品一样。人类正在耗尽地球的自然资源，为了减少地球的人口数量，我们应该少生孩子，而不是克隆出更多的人。我为那位不能生育的女士难过，但是我要指出的是世界上有许多没有父母的孩子，如果能有一位妈妈，他们一定非常高兴。 波林卡特Dear Editor I would like to comment on your article , “The perfect copy “ . I think the scientific advances mentioned in your article are fantastic ! I am in complete agreement with human cloning . After all , scientists have been challenging moral ideas for centuries . Why should we stop them now ? On a personal note , cloning would totally tansform my life .Seven years ago , my 10-year-old daughter died of heart failure . She was beautiful , cheerful and bright . I miss her every single day. If I had the chance , I would clone her immedia
