For most of the twentieth century, people communicated by telephone or by mail. This is now changing, and email is becoming the preferred method of communication. It's faster than traditional mail. 1．   . As email is becoming popular, here are some rules we need to know.
 Be polite and friendly.
Start your message with a greeting. If you are writing to a friend, you can begin with Hi, Sandra. If you are writing to your teacher, begin with your message with Dear Mr. Atonso. 2．    Many people just type their names. Others say Bye, Cheers, or use abbreviations（缩略语）like BFN（bye for now）.
 Look good.
When someone receives an email message from you, they might not know anything about you. 3．  , so make yourself look good. Type your message, and then read it again. Sometimes sentences seem clear when you write them, but they don’t make sense when you read them back.
4．   
If you start to use your email several times a week, your message box will soon fill with mail. After a few weeks, you can have a list of 60 or 70 messages! It is easy to delete the message you don’t want any more. 5．   , you can save them in folders（文件夹）.If you don’t know how to do that, just ask your friends for help. It only takes a few minutes to learn.
