用作宾语的从句叫做宾语从句(object clause)。宾语从句中的语序是陈述句的语序。在学习宾语从句时要得法，抓住要点。

　　一、宾语从句中的时态。

　　1.如果主句的时态是一般现在时或一般将来时，从句的时态则根据具体情况或具体意义来确定。如：

　　① I don't know when he came back.

　　② Do you know where they will go this summer holiday?

　　③He is worried about whether he has passed the English exam.

　　④ Please tell us what we should do next, OK?

　　⑤ Will you please tell me how I can get to the post office?

　　2.如果主句的时态是一般过去时，从句的时态则相应地使用一般过去时/过去将来时/过去完成时/过去进行时等。如：

　　① He said that he didn't find your lost pen.

　　② My parents told me that they would go to Beijing.

　　③ The policeman asked him what he was doing at midnight yesterday.

　　④ I told you yesterday that I had returned your book. Why do you ask for it again?

　　3.如果宾语从句所叙述的是客观真理、自然现象、名言警句或谚语等，不管主句是什么时态，从句都用原时态。如：

　　① Our geography teacher told us that the earth goes around the sun.

　　② When I was young, my father often told me that knowledge is power (力量).

　　二、宾语从句前通常需要有引导词。

　　1. 如果宾语从句是由陈述句转变而来的，其引导词用that，常可以省略。如：

　　I hope (that) I can study English better.

　　2. 如果宾语从句是由一般疑问句转变而来的，其引导词使用if / whether, 意为"是否"。 如：

　　Mr Chen asked , "Are you all here?"→Mr Chen asked if / whether we were all here.

　　3. 如果宾语从句是由特殊疑问句转变而来的，其引导词使用连接代词what / which /who / whose 或 连接副词when / where / why / how 等。这些连接词都要充当从句中的一个成分，故不能省略。如：

　　Tom asked me， "When did you begin to study English?"

　　→Tom asked me when I began to study English.
