　　Man always wanted to fly. For hundreds of years they watched birds flying and wished that they could fly too. Birds fly very easily. Then they spread (展开) their wings and float (漂浮) on the air. The air keeps them up. Men knew how to make kites hundreds of years ago. Kites could stay in the air for many hours. “If birds and kites can stay up in the air, perhaps we can,” they thought.

　　At first they made wings like birds. Then they jumped off high buildings in order to fly. Many men did this but they all failed. After many failures (失败) they stopped trying to fly with wings. Then two brothers tried another way. They tried balloons (气球). “Hot air is lighter than cold air,” they said, “That is why hot air goes upwards. If we fill a balloon with hot air, it will go upwards.

　　After many experiments, they made two men go up in a balloon full of hot air. A great crowd of people watched. The balloon rose to a height (高度) of 900 metres. The wind blew it along for nine kilometres. Then it came gently back to earth. For the first time man travelled through the air!
