　 C. where did she live　　　　 D. where she lived

　 [解析]答案：D。该题考查的是宾语从句的语序和时态。宾语从句应用陈述句的语序和时态，所以应选D。

2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态(一般过去时， 过去进行时， 过去将来时，过去完成时)。例如：

He asked what time it was.

He told me that he was preparing for the sports meet.

He asked if you had written to Peter.

He said that he would go back to the U.S. soon.

1. 如果主句的时态是一般现在时，宾语从句该用什麽时态就用什麽时态。

如：

I don’t think (that) you are right.

Please tell us where he is.

Can you tell me how I can get to the railway station?

宾语从句的语序应为陈述句的语序。例如：

I hear (that) physics isn’t easy.

I think (that) you will like this school soon.

Can you tell me how I can get to zoo?

Please tell me when we’ll have the meeting.

3. 由if或whether引导的宾语从句。If和whether在句中的意思是“是否”。例如：

I want to know if (whether) he lives there.

He asked me whether (if) I could help him.

2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如：

Do you know who (whom) they are waiting foe?

He asked whose handwriting was the best.

Can you tell me where the No.3 bus stop is?

I don’t know why the train is late.

宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或

形容词的宾语。根据引导宾语从句的不同连词，宾语从句可分为三类。

1. 由that引导的宾语从句。That只有语法作用，没有实在的意义，在口语

和非正式文体中可以省略。例如：

He said (that) he wanted to stay at home.

She doesn’t know (that) she is seriously ill.

I am sure (that) he will succeed.
