       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, 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 will get something in return.

       Of course, as we know, dogs can be used to guard a house, and elephants can be used to do some
