英语语法点：宾语从句中的人称变化和标点的实用

　　1. 从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；假如是第二人称，则与主句的宾语一致；如果是第三人称，不用变革的英语语法点。如：

　;May I use your knife?” He asked me. →He asked me if he might use my knife.

　　“Do you know her telephone number?” He asked me.

内容来自

　　→He asked me if I know her telephone number.

　　2. 宾语从句的标点均由主句决定。主句是陈述句，用句号；主句是疑难句，用问号。英语语法点如：

　　Who will give us a talk? I don’t know. →I don’t know who will give us a talk.

　　Do you know? Where does he live? →Do you know where he lives?
