第一节:阅读表达(共5小题;每小题2分,满分10分)

You are in a beautiful place enjoying the landscape, maybe fishing, but suddenly the peace and quiet is interrupted by the noisy sound of a cell phone! Cell phones are everywhere, and some people don’t know what the limits of cell phone use are.

Nowadays,that’s the biggest problem. People disturb other people, first with the ringing of their cell phones and then with their conversations because they usually speak very loudly. Not everybody in a public place should have to listen to private conversations.

People need to learn how to use cell phones correctly. If there is an emergency, cell phone are acceptable; but remember that just a few years ago few people had cell phones and the whole society survived! Nowadays people can’t seem to live without using the cell phones. They talk in restaurants, in restrooms, in hospitals, and at parties. It’s incredible!

It’s like smoking. Just as people don’t want to be bothered by smokers, they don’t want to be disturbed by cell phone talkers. Our society has to learn to respect other people. It would be great if loud talking was seen as really bad manners. The use of cell phones must be restricted in places such as cinemas, theatres, museums, classrooms, and hospitals.

Nowadays, people just laugh when a cell phone rings in these places, but it’s just the beginning. So in the future I think things are going to change. They should have got tickets when they use them in inappropriate places, like people get parking tickets when they park in inappropriate places. So, we have to write some rules to restrict, or even prohibit, cell phone use in some places. New rules of etiquette (礼仪) are needed for new behaviors in our lives such as using cell phones. It’s going to have to be part of our education in the future.
