题目：
Can we make animals work for us? Some scientists think that we can teach animals to do a lot of things for the people. They say that in a farm or on TV, you may see elephants, monkeys, dogs or some other animals doing a lot of things. If you watch carefully, you may find those animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat.
We all know elephants can carry large logs, and dogs can look after houses. And we can even teach animals to work in factories. In America, for example, people have used apes to help make cars, and scientists think that those large monkeys may, one day, drive trains. Now people are trying to get them to do something just like man.
