Most children now chat daily either online or through their mobile phones. They are connecting to a huge number of other children all over the world. Some are shy “in real life” but are confident to commun icate with others online; others find support from people of their own age on relationship issues, or problems at home.

Sometimes the online world, just like the real world, can introduce problems, such as arguments. Going online is great fun, but there are also a few people who use the Internet for offensive (冒犯性的) or illegal aims. Children must be made aware of both the good things and the dangers.

To keep children safe your management must cover the family computer. Just as you decide which TV pro-grams are suitable, you need to do the same for the websites and chat rooms your children visit. Remind your children that online friends are still strangers. Re-minding them of the risks will keep them alert (警惕).

Computer studies are part of schoolwork no w, so it’s likely that your children may know more than you do. We get left behind when it comes to the latest gad-gets and the interactive areas of websites, like chat rooms and message boards, which are especially strange. The language of chat is strange to many parents, too. Chatters love to use abbreviations (缩写) such as: atb — all the best, bbfn — bye bye for now, cul8er — see you later, gr8 —great, Idk —I don’t know, imbl — it must be love, kit — keep in touch, paw — parents are watching, lol — laugh out loud, xlnt — excellent!
