阅读理解。 I was born in a small river. When I was young, the river was my home. I didn't know my parents, but I had hundreds of brothers and sisters. I swam about and played all day with them. At that time I did not look like my parents. I had no legs, but I had a long tail. So I looked like a fish. Then my tail became shorter and shorter. And now I have four legs and a very short tail (尾巴). I know I'm going to have no tail at all soon. I'm going to be like my parents. Then I'm going to jump out of the water. I'm going to live on the land and in the water, too. I'm going to eat a lot of insects (昆虫)-a lot of bad insects.
