初中英语必备知识

1、宾语从句的语序问题

以上介绍了三种宾语从句,同学们一定要注意,在疑问词或if/whether引导的'宾语从句中,一定要用陈述句语序。

asked how old I was.

We don’t know where her office is.

My teacher wanted to know if I like English.

2、宾语从句的时态问题

一般情况下宾语从句的时态必须和主句的时态保持一致:

当主句的谓语动词是一般现在时时,宾语从句中的谓语动词不受时态限制。

says that she is a student.

She says that she was a student two years ago.

She says that she will be a college student soon.

She says that she has been a college student for 3 years.

当主句的谓语动词是过去时时,宾语从句中只能用过去的某种时态。

told me that he would leave soon.

He said that he was watching TV.

He didn’t tell me whether he had finished this homework.

但如果宾语从句中讲述的客观事实、一般真理或自然现象时,则不受它限制。

teacher told us that Yangtze River is the longest river in our country.

Father said (that) the sun always rises in the east.
