When is the word versus usually used?
It is China versus Brazil in the volleyball final.
We were wondering who would win in the case of
the ill family versus the factory who polluted
their water.
Versus is usually used when discussing sports
competitions or the law, which means that two
teams or sides are against each other.
3
Why versus is used here?
Do you think there is conflict between science
and nature? What might the conflict be? What kind
of topics might be discussed in this unit?

Look at the pictures and have a discussion.
the worlds first cloned mammal created by
Scottish scientists in 1996 sparked worldwide
interest and concern after its birth died in 2003
because of lung cancer

Idaho Gem the worlds first cloned mule born on 4
May 2003 He is an identical genetic copy of his
brother, a champion racing mule called Taz . only
got the 3rd in a competition

created it with a cell taken from its mother,
Rainbow. It was born in December 2002.

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

backwards) first genetically modified monkey

The technology is different from that used for
Dolly.

Discussion

• From just the pictures, can you identify the
  differences between the cloned animals and normal
  ones?
• 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? For example, does the mule in Picture 2
  run as fast as his brother?

12
What do you know about cloning?
Cloning is a new biotechnology which produces an
exact copy of an animal or a plant from its own
cell. There have been disputes on the possible
effect on its application(??) in human society.
Some people believe cloning technology can be
used to cure the patients with genetic diseases
and save a lot of peoples lives. However, other
people insist that cloning technology will cause
ethical problems and violate human rights. No one
can predict how negative the consequences could
be. We have to take cautious approach.
13
What other cloned animals do you know about?
Since Dolly was born, over 500 mammals, e.g.,
cow, cats, goats, mice, have been cloned
successfully. Many countries, including Germany,
France, Canada, Switzerland, Austria, Norway and
South Africa, have banned human cloning since
Dollys birth, so no human being has been cloned
successfully yet.
14
Do you think it would be a good idea to clone
humans some day? Why or why not?
I dont think it is a good idea to clone humans
even though we might have the ability to do so in
the future. The disadvantages outweigh the
advantages. It may bring about great confusion.
