阅读下面短文，并根据要求完成文章后的题目。

Chatting online can be great fun，but remember, you never really know who you are talking to online．It could be someone trying to trick you，some kind of weirdo（古怪的人），or someone really dangerous．Here are some tips to help you keep safe：

●  1. Never use your real name in chat rooms．

●  2. Never tell anyone personal things about yourself or your family—like your address or telephone number ，or the school or clubs you go to．That goes for sending them photos as well（that way if you don’t want to hear from them again，you only have to log off.） Remember, even if somebody tells you about themselves，never tell them things about you.

●  3. If you arrange to meet up with someone you’ve only spoken to once, remember that they might not be who they said they were，so only meet people in public places and take along an adult.

●   4. Never respond to nasty（淫秽的）or rude messages，and never send any either! If you feel uncomfortable about the way a conversation is going，or if it’s getting really personal，save a record of it and stop the conversation．That way you can show someone and ask what they think．

●  5. Be careful with any emails or links that people send you，they might contain nasty （淫秽的）pictures，or computer “viruses” that could ruin your computer．So if you____________                    , don’t open it．
