問題詳情:
Can animals be made to work for us? Some scientists think that one day animals may be taught to do a number of simple jobs. They say that in a film or on TV we may see elephants, or monkeys, dogs, bears, or other animals doing a lot of things. If you watch carefully, you may find that those animals are always given something to eat in return for doing them. The scientists say that many different animals may be taught to do a number of simple jobs if they know they will get something to eat in return.
Of course, as we know, dogs can be used to guard a house, and elephant can be used to do some heavy jobs. And we can also teach animals to work in factories. Apes(猿猴), for example, have been used in America to help make cars and scientists believe that these large monkeys may one day get in (收割)crops and even drive trains.

A. they have enough food to eat
