Answer the questions according to the passage you read.
A great French writer said that we should help everyone as much as we can, because we often need help ourselves. Sometimes the small can help the great. And he told the following story.
An ant was drinking by a small river and fell in. She tried her best to reach the bank(岸), but she couldn’t move at all. The poor ant got too tried but was still doing her best. Then a big bird saw her. The bird threw a piece of wood into the water. With it the ant reached the bank again. While she was resting and drying herself on the grass, she heard a man coming up. The man was walking with a gun(枪) in his hand. As soon as he saw the bird, he wanted to kill her. But the ant bit(咬) him on one of his feet and at the moment the bird flew away at once.
The ant saved the bird’s life.
