Many children use the Internet to get useful knowledge and information, and to relax in their free time. But some of them are not using in a good way. Here are some rules to make sure you are safe and have fun on the Internet.

Make rules for Internet use with your parents. For example, when you can go online, for how long and what activities you can go online.

Don’t give your password (密码) to anyone else, and never leak out the following information---your real name, home address, age, school, phone number or other personal information.

Check with your parents before giving out a credit (信用) card number.

Never send a photo of yourself to someone in e-mail unless your parents say it’s OK.

Check with your parents before going into a chat room. Different chat rooms have different rules and attract different kinds of people. You and your parents must make sure it’s a right place for you.

Never agree to meet someone you met on the Internet without your parent’s permission (允许). Never meet anyone you met on line alone.

Always remember that people online may not be who they say they are. Treat everyone online as strangers.

In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.

Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.

Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods(方法), more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.

We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.

We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.

What can we do to solve these problems?

If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.
