文档简介
课件13张PPT。Unit3 Science versus nature
Welcome to the unitLead-inScience 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?
Explanation
Clone: produce an exact copy of an animal or a plant from its own cells Dolly the world's first cloned
adult animal. The
scientists who cloned
Dolly are to stop
experiments involving
genetically modifying
pigs for human organ
transplants because
of concerns that deadly
new diseases could
be passed on to people. Picture-talk The world‘s first
cloned mule(驴),
was born on May
4. He is created
from a cell of
his brother.kitten Rainbow The world's first cloned cat, kitten, named
Cc. It was created using a cell taken from
an adult cat,Rainbow.The world's first cloned pigs were produced
from an adult
female pig using a different technique
from the one that produced Dolly. Five cloned pigsA pair of new-born cloned calves They are the second adult-animal clones research centre said the new technique would be used to breed better cattle
strains with higher-quality beef or greater milk capacity. The first cloned monkey is another incremental step toward designing and perfecting new treatments for human genetic disorders. From these pictures, can you identify
the differences between the cloned
animals and normal ones?Discussions
In your opinion, what might be the
differences between these cloned
animals and normal ones?
Can these cloned animals lead a
normal life as normal animals?
For example, does 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?
