Host: Hello! I'm Gavin from All Talk 970 FM. Welcome to our program. Today our topic is part-time jobs. Are they good for school children or not?

　　Headmaster (校长) : Certainly not. Children have got two full-time jobs already: growing up and going to school. Part-time jobs make them so tired that they fall asleep in class.

　　Mrs Bttck: I agree. I know school hours are short, but there's homework too, and children need a lot of sleep.

　　Mr Black: Young children perhaps, but some boys stay at school until they're eighteen or nineteen. A part-time job can't harm them. In fact, it's good for them. They themselves earn their pocket-money. And they see something of the world outside school.

　　Businessman: You're quite right. Boys learn a lot from a parttime job. And we mustn't forget that some families need the extra money. If the students don't take part-time jobs, they can't stay at school.

　　Host: Well, we have got two for, and two against. What do our listeners think?

阅读下面短文并根据短文内容，从短文后面每题所给的选项中选择最佳答案。

　　My uncle lives in New York City. He likes fishing. Every summer he goes fishing in the Adirondack Mountains.

　　One day this summer he took me to one of the beautiful lakes here. The sun was shining in the blue sky over the lake. My uncle caught some big fish, but I could not catch any. He said, “When I was a child, I caught a lot of fish here. But now there aren't many fish. In some of the lakes there are no fish at all.”

　　Then one day I read an article about acid(酸的) rain in a magazine. I learned many things. Gases(废气) from factories and cars go up into the sky, and the wind carries them far away. Later they come down with the rain in other places. That a acid rain.

　　Fish eggs and young fish are killed by even a little acid in the water. Today there are no fish in about 200 lakes in the Adirondack Mountains.

　　Acid rain is becoming a big problem all over the world today. Canada and some countries in northern Europe have the same problems. In Canada, for example, a lot of trees are dying(枯死) because of acid rain.

　　At the end of the article the writer says, “When I stand here and look at these lakes after ten years, what will I see and hear? Will fish jump again? Will birds sing their happy songs? Or will it be a silent spring?”

　　What should we do to stop acid rain? Is it too late now? No, I do not think so. All of us should work together to stop acid rain.
