When the weather is hot， you go to a lake or an ocean. When you are near a lake or an ocean， you feel cool. Why? The sun makes the earth hot， but it can not make the water hot. Though the air over the earth becomes hot， the air over the water stays cool. The hot air over the earth goes up， then the cool air over the water moves in and takes the place of the hot air. When you are near a lake or an ocean， you feel the cool air when it moves in. You feel the wind and the wind makes you cool.

Of course， scientists cannot answer all of our questions. If we ask “Why is the ocean full of salt？” scientists will say that the salt comes from rocks. When a rock gets very hot or very cool， it cracks (崩裂) ， and rain falls into the cracks. The rain then carries the salt into the earth and the rivers. The rivers carry the salt into the ocean. But then we ask “What happens to the salt in the ocean？ The ocean does not get saltier every year. “ scientists are not sure about the answer to the question.

We know a lot about our world. But there are still many answers that we do not have， and we are curious(好奇的).

Unlike other people, my Olympic heroes are not Olympic champions or the important people on the Olympic Committee (委員會). They are just the ordinary ones who do the everyday things. They work without the recognition (公認) the famous people get. They are the Olympic volunteers.

These people aren't the great stars of sport. They just want to do their part for the Olympics by smiling and helping the Games go smoothly.The stars of the Games are like brightly colored sailboats on the sea, racing through the waves. How lovely to watch them! But the volunteers are the wind, which nobody sees. Without the wind the sailboats would not be able to move and no one would want to watch them. The volunteers breathe (發(fā)出) the wind of life into the athletes.

The volunteers may never win medals, but they always do their best to encourage the athletes, whether the athletes win or lose.Some might think what the volunteers do is boring, hardly worth mentioning (提及). But in my eyes, they are as important as the champions and the stars. They are just as much heroes, despite (盡管) not appearing in newspapers or on TV.

I truly admire them and I will always cheer for them. They are my Olympic heroes.

1.From the first paragraph we know that the writer’s heroes are .

A. Olympic champions

B. the important people on the Olympic Committee

C. the ordinary people who don’t do the everyday things

D. the Olympic volunteers

2.The writer compares the Olympic volunteers to.

A. brightly colored sailboats B. the wind

C. the sun D. the water

3.What does the underlined word “athletes” in Paragraph 3 mean in the passage?

A. 教練 B. 裁判

C. 運動員 D. 觀眾

4. What does the writer think of the volunteers’ work?

A. boring B. important

C. interesting D. excellent
