We have learned more about protecting our environment. Will you still do this like the person?

Now we ‘ll talk about another topic in this unit.

From the second picture, you may think of the world famous cloned

sheep--- Dolly.

Do you know sth. about cloning?

What do you know about them?

“Cloning” is a new technology which produces an exact copy of an animal

or a plant from its own cells. Dolly was the first cloned mammal created by a Scottish scientist and his group

in 1996.She was exactly the same as mother, in appearance and in genes.

What do you think of the new kind of technology? Does it have advantages or disadvantages?

The new kind of technology has caused widespread discussion. It can help cure many diseases, save lots of people’s lives and even prevent some endangered animals from dying out.. However, on the other hand, if it is used to clone human beings, that is against the laws of nature.

Look at the following pictures and study them. Can you tell what is the main feature of cloning?

can you identify the differences between the cloned animals and normal ones?

Dolly is together with her mother.

The mule in the picture is the world’s first cloned mule. It was born on 4 May 2003. His name is Idaho Gem.

The kitten in the picture is called Cc. Its name is from “Copycat”. It was born in December 2002.

These female pigs are also cloned. They are born on Christmas Day 2001. They are Noel, Angel, Star, Joy and Mary.

The pair of calves were born on 5 July 1998 in Ishikawa, Japan. They were two years younger than Dolly, being second adult animal clones in the world.

The name of the cloned monkey is ANDi. It is from “ inserted DNA” spelt backwards.

It is the first genetically modified monkey. The technology is different from that used

for Dolly.

The cloned animals or plants are exactly the same as the original ones.

can you identify the differences between the cloned animals and normal ones?

In your opinion, can the mule in Picture 2 run as fast as his brother?

Do you think it would be a good idea to clone humans some day? Why or why not?

If possible, do you want another person to be exactly the same as you?
