　Tom liked to find out how things worked very much.

　One morning when young Tom was five, he went out 　1　 his playmates. But no one was in the street. So he went to ask the boy of his neighbour (邻居). When he walked into the gate of the neighbour's, he saw they 　2 　breakfast. So he 　3 　wait out of the room.

　Suddenly he saw a hen (母鸡) sitting in an old basket by the window. He was 　4 　. Why was she sitting there? What 　5 　earth was she doing? He went over as he was thinking. The hen was frightened and ran away. Tom sat down and 　6 　carefully. He put his hands on the eggs. They were warm. After a while he saw a young chick climbing out of an egg. He understood that the hen was hatching (孵鸡). The 　7 　could make a chick 　8　 from an egg. So he ran home at once, took out some eggs, put them in a basket, sat on them and then began hatching. When his father saw this at noon, he asked 　9 　Tom was doing that for. Tom said 　10 　. Instead, he asked his father why he was not able to hatch chicks while hens could.
