Have you ever hoped a toy balloon? They are very light. But there are much bigger balloons can fly very high up in the sky. They are big enough to carry people. They are called hot-air balloons.
To make a hot-air balloon go up, turn on the burner(燃烧器). That will make the air inside the balloon hotter. Then the balloon will go up.
To make the balloon go down, turn off the burner. The air inside the balloon will get cooler. Then the balloon will go down. Underneath(在….下面) the balloon there is a large basket. That is where the pilot and the passengers go.
The burner is just above the basket. You can stand in the basket and turn the burner on and off. The balloon will go where the wind is blowing the right way! Do you want the balloon to go somewhere special? First make sure the wind is blowing the right way!
People have been flying in hot-air balloons for over two hundred years. Before planes it was the only way of flying. Today people fly in hot-air balloon for fun. Some people like to race hot-air balloons.

解析：更大的气球在天空中飞得很高。他们是大到足以携带人。他们被称为热气球。打开燃烧器。这将使气球内的空气更热。然后气球就上去了。关闭燃烧器。气球内的空气冷却器。然后，气球会往下走。在热气球的下面有一大筐。这是飞行员和乘客乘坐的地方。
你想气球去什么特别的地方吗？首先确保风吹正确的方式！人们一直在热气球飞行两百多年。在飞机发明之前，它是唯一的方式飞行。今天，人们在热气球飞行是为了乐趣。有些人喜欢热气球比赛。
【小题1】细节理解题，根据文中语句“Have you ever hoped a toy balloon? But there are much bigger balloons can fly very high up in the sky. They are big enough to carry people. They are called hot-air balloons.”理解可知。热气球比玩具球要大得多，故选B。
【小题2】细节理解题，根据文中语句“Underneath(在….下面) the balloon there is a large basket. That is where the pilot and the passengers go.”理解可知。人坐在下面的篮子里，故选A。
【小题3】细节理解题，根据文中语句“To make a hot-air balloon go up, turn on the burner(燃烧器). That will make the air inside the balloon hotter.”理解可知。想让气球高飞，必须给气球里的空气加热，故选C。
【小题4】细节理解题，根据文中语句“To make the balloon go down, turn off the burner. The air inside the balloon will get cooler. Then the balloon will go down.”理解可知。想让气球下降，必须使气球里的空气温度降低，故选D。
【小题5】细节理解题，根据文中语句“Do you want the balloon to go somewhere special? First make sure the wind is blowing the right way!”理解可知。气球升空后，有风向决定到底去哪里，故选C。
