Many students want to find friends on the Internet as a way of practising their language skills and learning more about new cultures. Traditional pen pals were the primary source for such contacts, and students could write each other letters. With the Internet, finding friends has become much easier，and such relationships are called key pals. However，care and consideration should be given when finding friends on the Internet：
Search the Internet for reputable(有信誉的）services. Look for reviews of such sites to learn more about other students' experiences. Don't join a service until you have done your research.
Check to see if you can use a nickname ，instead of _______，to protect your identity.
Never give personal information to anyone, including your home address ，phone number, and birthday.
.Stop contact with others if you feel uncomfortable with the topics of conversation. Again, if you protect your identity , this will be easier to do. Tell your teachers, parents, or even local law enforcement (执法组）if problems arise.
.Try to use the language you are studying in the classroom in your communication with others.
.Ask appropriate(适当的）questions that will also help you learn about other cultures. Remember that someone's personal experience might help you to understand a whole culture. You have to talk to many different people ，and this will get you started.
