　　Here’s a story about Ming’s life on the waters. Ming has lived all his life on a wide r  1   in China. His home is a large house-boat with a roof, one of hundreds that move up and down. In about six years he has not once been on l   2     but he is never lonely. He is a strong swimmer. In fact, he could swim before he could walk. When he wants to play with his f   3    he just swims across to their boats or asks them to v  4    him.

　　Ming’s father is a fisherman, but he never u5     a line or a net（网）. Great black birds called cormorants do the fishing for him. Rings（圈）have been put around the birds’ n  6   so that they cannot eat the fish they catch. They have been t   7    to bring the fish to people. And then people reward（奖励）them with a fine big fish as soon as their work is f   8    Ming loves watching the cormorants, but better still he likes going s  9    with his mother. The shops, of course, are boats very like his o   10   .

　　Can animals be made to work for people? Some scientists think that one day animals may be trained to do a number of simple jobs i  1    of people. They say that at a circus（杂技场）,for example, we may see elephants, monkeys, dogs and other animals doing q  2    skillful（熟练的）things. Perhaps you have seen them on the television or in a film. If you watch closely, you may find that the trainer always g  3   the animal some sugar o4   a piece of fruit as a reward. The scientists say that many d  5   animals may be trained to do a lot of simple things if they know they will get a reward f  6  doing that.

　　Of course, as we know, dogs can be trained to look after a house, and soldiers in both old and modern t  7   have u  8   geese to give warning（警报）by m9   a lot of noise when an enemy comes near. And also it may be possible to train animals to work in families or f   10   .
