八年级上册英语语法总结

学习初中英语，语法是非常关键的一部分，下面总结了初二上册英语重点语法知识，供大家参考。

一般疑问句

1.will+主语+do? Will Sarah come to visit me next Sunday?

2.there be 结构的一般疑问句：Will there + be?

Will there be fewer trees? Yes, there will. / No, there won’t

否定句构成：will + not (won’t )+do

特殊疑问句

特殊疑问词+will +主语+?What will Sarah do next Sunday?

根据例句，用will 改写下列各句

例：I don’t feel well today. (be better tomorrow)

I’ll be better tomorrow.

过去进行时

过去进行时表示过去某一点时间正在进行的动作或者过去某一段时间内一直进行的动作。

1.构成

was /were + doing，例如：

I was watching TV at 9 o’clock last night.

2.过去进行时的标志词

at 8 o’clock last night, this time yesterday等。例如：

昨天的这个时候我正在吃午饭。

if引导的英语知识点

1.if引导宾语从句和状语从句的区别

if引导宾语从句时意为“是否”，从句中该用什么时态就应用什么时态。

if引导条件状语从句时意为“假如”，从句中应用一般现在时代替一般将来时。

e.g.She wanted to know if you were a teacher.

I don’t know if the letter is yours.

They’ll go boating if it is fine tomorrow.

I’ll give it to her if she comes next week.

2.if引导宾语从句时多数情况下可以与whether互换，但如果要突出“究竟是……还是不……”这层意思时，通常用whether，并在后面的加上“or not”，即一般要选择whether构成whether…or not的结构。

e.g.Please find out whether the money is his or not.

Let me know whether you can come or not.

I want to know whether you can help me or not.
