二、宾语从句的语序：

宾语从句的语序是陈述语序，即“连接词+主语+谓语+其它成分”。特别强调：它的主语和谓语的语序是陈述语序，而不是疑问句的倒装结

构。

Can you tell me who(m) do we have to see?(╳)

Can you tell me who(m) we have to see?( √)

The teacher asked the students what they were doing.(思考: what在从句中的成分)

陈述句变为宾语从句时,要注意人称和时态的变化,语序不变。 eg. She said, “I will leave a message on the desk.” à She said

she would leave a message on the desk.

一般疑问句和特殊疑问句变为宾语从句时,也要注意人称和时态的变化,后面接陈述语序。Eg. “Where are the tickets?” I asked him.

à I asked him where the tickets are.

三、宾语从句的时态呼应：

宾语从句中谓语动词的时态，常常受到主句谓语时态的制约，此为时态呼应。如果主句谓语是一般现在时或将来时，从句谓语的时态不受

限制;如果主句谓语的时态是一般过去时，从句一般要随着改为相应的过去时态(一般过去时、过去进行时、过去将来时、过去完成时)。

eg. I thought (that) you are free today. (╳)

I thought (that) you would be free today. ( √)

【注意】当宾语从句叙述的是客观真理时，不管主句谓语的时态如何，从句都用一般现在时。

eg. The teacher told us (that) the earth moves around the sun.

四、其他需要说明的问题：

1、标点由主句决定，如主句是陈述句、祈使句，则用句号;是疑问句则用问号。

eg. I heard she had been to the Great Wall. Can you tell me which bus I should take?

2、要注意个别句子中主从句人称的一致。

▲五、宾语从句和状语从句的区分：

eg. 1) I will go out tomorrow if it is fine tomorrow.

2) I don’t know if the train has arrived.

句1中if引导的是状语从句。这个从句表示“条件”，修饰主句。整个句子的意思是如果明天天气好，我就出去。句2中if引导的是宾语从

句，充当谓语动词don’t know的宾语。整个句子的意思是我不知道火车是否已到达。
