     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(评论) 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 (绰号) instead of __________, to protect your identity(身份).

     ◎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 if problem

arise.

     ◎Try to use the language you are studying in the classroom in your communication(交流) with others.

     ◎Ask proper 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.
