T: Of course, we should turn on our computers and connect to the Internet. Then open the e-mail program. OK, let’s know the buttons. First, this button写信 means writing a letter. Click here, another box will appear and then click on 收件人 . It means the receiver’s e-mail address. The third step is to click on 主题, which means subject. Type the title of your e-mail. The fourth step is to write your e-mail in this big and empty box on your screen. The last step is to click on 发送 , which means sending. Now, do you understand? Can anybody send an e-mail now? Once again … OK? S11, please! Think it over and try it, please.
S11: OK, let me have a try.
(让学生演示一遍，确保学生都明白发邮件的具体步骤。教师板书生词，释义，领读并要求掌握。)
