初中宾语从句知识点：从句中人称与标点的变化

　　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;如果是第二人称，则与主句的宾语一致;如果是第三人称，不用变化。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. 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;主句是疑问句，用问号。如：

　　Who will give us a talk?I dont know. I dont know who will give us a talk.

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