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.

初三英语知识点归纳4

一般将来时

表示将要发生的动作或存在的状态,常与表示将来时间状语如 next year,tomorrow等连用。注意:在Will you …?问句中,回答必须是 Yes,I will.或 No,I won't而不能用Yes,I shall. No, I shan't.来回答过去将来时:过去将来时不可以单独使用,它一般在宾语从句中作间接引语,表示从过去某一时间看来将要发生的动作或存在的状态。如:They told me that they would go to work in Guangdong.

现在完成时

顾名思义,现在完成时表示的是已经完成的动作,但动作造成的影响还在,常被just,already,yet 等副词修饰。如:He has already gone to Tianjin. 对现在造成的影响是他已经不在这儿了。现在完成时还可用来表示过去发生的动作一直延续到现在,常带有for或since等表示一段时间的状语。如:Mr Wang has lived here since 1983.表示说话前发生过一次或多次的动作,我们常用"过"来表示,常带有twice, once, ever, never等时间状语。如:I've never seen that film.

过去完成时

我们可以用"过去的过去"来概括过去完成时,表示过去某一时刻或某一动作之前已经完成了的动作,通常与by,before等构成的短语或when, before, after引导的从句连用。也可表示过去某一时间开始,一直延续到过去另一时间的动作,常和for或since构成的时间状语连用。用法和现在完成时大致相同,只不过又向前推了一个时态。
