二、宾语从句的语序，

宾语从句的语序必须是陈述语序，既连接词+主语+谓语+其他成分

I believe that they will come soon.

特例：有下列常见的问句，作为从句出现，是“不改变语句顺序”的。

1. What's the matter?

2. What's wrong?

3. What's up？

4. What's the problem?

5. What's your trouble?

三、宾语从句的时态。

宾语从句的时态受主句的限制即：主句是一般现在时态，从句根据实际情况而定；主句是一般过去时态，从句用相应的过去的时态。如果从句的动作发生在主句之前，则从句要用过去完成时态。

1) She says that she is a student.→ She said that she was a student.

2) She says that she will fly to Japan in a week. → She said that she would fly to Japan in a week.

3) She says that she has finished her homework already. → She said that she had finished her homework already.

（1）如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一般现在时态。 The teacher said that the earth goes round the sun.

（2）Could you tell me…是用来征询对方的意见，语气委婉，并不表示过去。

Could you tell me when we will visit the Histury Museum?

注意事项：

（3）由陈述句变成宾语从句时，要注意人称的变化。

She said: “I have been to England before.” → She said that she had been to England before.

She asked me: “Do you like maths?” → She asked me if I liked maths.

（4）宾语从句与简单句的交换。

由连接代词和连接副词引导的宾语从句，如果宾语从句的主语和主句的主语是同一个人时，可以用“疑问词+不定式”做宾语的简单句结构。

I don’t know what I should do next. → I don’t know what to do next.

同位语从句

（一）一般来说，在主从复合句中，用作同位语的从句叫同位语从句。它通常跟在某些名词之后，用以说明或解释该名词表示的具体内容。可以跟同位语从句的名词通常有：advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word（消息），problem， question, doubt, thought等。

They were delighted at the news that their team had won.

当听到他们队获胜的消息时，他们欣喜若狂。

有时同位语从句可以不紧跟在被说明的名词后面，而被别的词隔开。 如：

The thought came to him that Tom might have returned the book.

他突然想起汤姆可能已经还了书了。

（二）引导词

1. The news that Mr. Li will be our new English teacher is true.

2. He hasn’t made the decision whether he will go there.

3. The question who should do the work is being discussed at the meeting.

4. I have no idea what the boy is doing in the next room now.

5. We haven’t yet settled the question where we are going to spend our summer vacation this year.
