宾语从句

1．宾语从句的引导词

　　（1）由陈述句变成的宾语从句，用that引导，语序不变。that在句中无实际意义，可以省略。如：

        He is a teacher. →He said (that) he was a teacher.

         I have already seen the film. →He said that he (had) already seen the film.

　　（2）由一般疑问句变成的宾语从句，用if或whether引导，表示“是否”，原来一般疑问句的语序要变为陈述句语序。如：

   　 Does the boy like English? →The teacher asked me if the boy liked English.

      Are they students?→I don't know if they are students.
