Receive, message, somebody,
二、重点句型
1)How often do you write e-mails to your friends?
2)Your message will be sent to the person you address.
3)It’s always nice to hear from Wu Hong!
三、重点句子解析
1. E-mail lets you send and receive messages around the world in seconds!  电子邮件使你在几秒钟之内就可完成向世界各地发送或接收信息！
【巧解句构】1）句子的时态是一般现在时，描述一种事实。
2）句子中使用的是let sb. do sth.结构，意为“让某人做某事”。其中的do sth.指的是send and receive messages。
3）地点状语around the world = all over the world意为“全世界”。            4）时间状语in seconds意为“在几秒钟之内”。
2.Do you want to receive e-mail somebody has sent you?
你想收到某人寄给你的电子邮件吗？
【巧解句构】somebody has sent you为定语从句，在复合句中修饰e-mail。
【要点剖析】receive为动词，意为“收到，接收”，同义词是get, accept；反义词是send。
            Receive/get a letter=hear from
            例如：She received warm welcome.你将受到热烈欢迎。
                  She received a letter from her friend.她收到一封朋友的来信。
3.It’s always nice to hear from Wu Hong!
【巧解句构】句中it作形式主语，真正的主语是to hear from Wu Hong。
【要点剖析】always意为“一直，总是”，使表示频率的词，表示频率的词还有：usually通常  often经常  sometimes有时候  never从来不
