when discussing sports Do you think there is conflict between competitions science and nature? or the law, which means that two teams What might the conflict be? or sides are against each This is an elephant versus another one. other.

Unit3 Science versus nature
Welcome to the unit
Lead-in

Science is developing so fast that sometimes it is beyond our imagination. Man has created many things such as Radios, TV sets and so on. What else has been created by man? Could you give us some examples?

Dolly was the first cloned mammal created by a Scottish scientist and his group in 1996.Dolly was exactly the same as her mother, in appearance and in genes. This new technology is called ‘cloning’, which produces an exact copy of an animal or a plant from its own cells.

Think about the relationship
between the title of the unit

Science versus nature and cloning technology.

The mule in the picture is the world’s first cloned mule. It was born on 4 May 2003. His name is Idaho Gem and his brother, Taz, was a racing mule that has won many competitions.

The kitten in the picture is called Cc. Its name is from ‘Copycat’. Scientists in the USA created it with a cell taken from its mother, Rainbow. It was born in December 2002.

I’m your Star. Love me please. Hi! I’m Joy. I’m happy-golucky everyday.

Just call me Noel, OK?

I’m the beautiful Mary

I’ m Angel, in your heart?

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

Form groups of four or six to discuss the further questions:
1. From just these pictures, can you identify the differences between the cloned animals and normal ones? 2. In your opinion, what might be the differences between these cloned animals and normal ones? Can these animals lead a normal life as normal animals? 3. Ask several groups to report their answers to the class. Allow different opinions and encourage further discussion.

Homework
Surf the Internet or refer to other sources for further information relevant to cloning technology, so as to finish the first two questions below the pictures. Make as many notes as possible.
