[精品课件]201x-201x学年高中英语 Unit 3 Science versus natureSection Ⅰ Welcome to the unit & R_图文

The Chinese scientist behind the development of the world's largest cloning factory in Tianjin, China, claims (声称) that the facility ( 设 备 ) possesses the technology to clone humans. He added that the only thing holding them back from cloning a person is the fear of how the public would react to it.

The giant cloning factory, which is due to open within the next seven months, is backed by Boyalife group in collaboration with South Korean company Sooam Biotech Research Foundation. It plans to be cloning 1 million cows a year by 2020, and also aims to clone other animals such as racehorses and police dogs. “Everything in the supermarket looks good — it's almost all shiny, good-looking, and uniformly shaped. For animals, we weren't able to do that in the past. But with our cloning factory, we choose to do so now,” Boyalife CEO Xu Xiaochun said.

There are different opinions when it comes to whether the cloned beef is safe for human consumption. The US Food and Drug Administration says it is, but the European parliament (议会) disagrees and has backed a ban on cloned animals and produce in the food chain, reports the Daily Mail.

I believe that human cloning is

wrong. If we toy with nature, we will

have to deal with ①


consequences②. Who knows what

could happen? Human life would just become a crop to be harvested③

[原文译文] 亲爱的编辑: 我认为克隆人类是错误的。如果我们戏弄自然,我们将不
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感到难过,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,他们一定会 非常高兴。
