Spending a long time in front of the computer may cause headaches, eyestrain（眼睛疲劳）or other physical problems. Make sure that your child spends only one or two hours a day in front of a computer screen. Write a list of rules for using the computer and the Internet. Put the rules next to the computer. Here are some of the rules:

      ★Keep your computer in an open place where you can watch what your child is doing, and can control how long your child is on the computer.

      ★Discuss with your child which websites you are happy they are looking at, and have a look at your child’s favorite websites yourself.

      ★Make sure that your child doesn’t give personal information over the web (name, age, address, telephone number).

      ★Make sure that your child asks your permission before download（下载）anything.

      ★Make sure that your child doesn’t post any photos of his or hers on the web．

      ★If your child wants to use a chatroom（聊天室）, make sure that you have a look at it first. Be around when your child is chatting.

★Teach your child not to meet anyone that they have met on the  web. If he or she does meet someone, an adult should be with him or her and the meeting should be in a public place.

    Have you ever posted your photos on the Internet? Would you mind if people cut part of your photo, perhaps your face, and paste（粘贴）it into other photos as a joke? Most people would not like to be made fun of in this way. However, it is not uncommon for people to find such pictures of themselves on the Internet.

We are living in an age of information explosion. People work, play and communicate with others over the Internet. However, we must always bear in mind that some people may use others personal information for unpleasant purposes. A good example of this is what happened to a 25-year-old man. He received an e-mail that appeared to be from his bank, asking for his bank details. However, after he sent his account(账户) number to the sender, he found that money was  stolen out of his bank by online criminals.

This story warns us and reminds us never to tell strangers information such as our real names, parents names, telephone numbers or home addresses. Remember to remove any private information, like your photos, after using another person's computers. Also remember not to give out unnecessary but important information when filling in online forms. We need to learn to keep our private information safe. This is the key to protecting ourselves in a world where the Internet is becoming more and more important.
