On 5 July 1996, a lamb was born in a shed in Scotland．It was called Dolly and it was an exact copy, or clone of another sheep．A clone is a method of copy a living thing．Scientists have been able to clone plants and bacteria(细菌)for a long time．Now that Dolly has been born, we can clone adult animals and probably even humans as well! In July 1998, scientists cloned twenty-one mice using the same method that was used to make Dolly．These proved that this way of cloning really works．

Making a copy of a living thing is much more difficult than making a copy of something that isn’t living(1ike a mountain bike)．For many years, people have tried to make robots that look and behave like humans．But in real life, scientists haven’t been very successful．Some countries are passing laws to stop scientists cloning humans, because it is such a terrifying thing to do．Robots still look like hunks of metal．They don’t move like we do, and they don’t think like we do．
