Swallows
简介
(1) 本文简单介绍了燕子的生活习性。
(2) 对小动物的介绍一般都是从细节到它的生活习性。
There are different kinds of swallows. Some swallows make their homes in the sand; others build their nests under the roofs. They make their nests of earth and grass.
It takes them several days to build a nest. They have to work in the early morning. The swallow lays five or six eggs at a time. The mother bird sits on them, and the father bird watches by her side and gives some food to her.
You must not think that when swallows fly over your head, they aren't working. No! Life is work to them. The young swallows eat a lot and they are busy catching the insects for them. So they have to work from early morning till late at night. At last the young birds can fly well, but the old ones can't rest. They began to think about their second family, for they have two broods every season.
When the second brood can fly, too, it's time to think about going to the warmer countries, and when spring comes, they'll return.
