Unit 3 Science versus natureSection Ⅰ Welcome to the unit

& Reading-Pre-reading

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, goodlooking, 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 2 produce in the food chain, reports the DailyMail.

The perfect copy

Scientists have announced① that

they have cloned② the first human embryo③. This has caused much debate round the

world. On the one hand④， some scientists

point out⑤ that if you clone an embryo,

you can produce valuable human tissues⑥ — such as bone or lung tissue — that

could be used to save⑦ human lives. On

the other hand⑧， many people, including

some scientists⑨， disagree and are

afraid that, if mankind toys with⑩

nature in this way⑪， we may be⑫on our way

to producing a reallife⑬ Frankenstein's

monster⑭.

Cloning is producing an exact⑮ copy

of a plant or an animal⑯using its cells⑰. The first mammal⑱ to be cloned

successfully⑲ from an adult cell was

Dolly the sheep⑳. She was born in 1996 and

died in early 2003, at a much younger age

than normal. When she was born, many

people were worried that cloning would

[第1～2段译文]

科学家们宣布他们已经克隆出第一个人类胚胎。这已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不同意见，他们担心人类如果用这种方式戏弄自然，我们可能将制造出一个现实生活中的弗兰肯斯坦怪物。

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。第一只成功地用成年动物细胞克隆出的哺乳动物是多利羊。她于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更多的疾病。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了人们的赞誉。

Ian 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.
