八年级英语重要知识点

一般疑问句

一、不用疑问词,但需要用yes或no回答的疑问句,叫一般疑问句。句末用问号“?”。

一般疑问句的基本用法及结构一般疑问句用于对某一情况提出疑问,通常可用yes和no来回答,读时用升调。其基本结构是“be / have / 助动词+主语+谓语(表语)”:

Is he interested in going? 他有兴趣去吗?

Have you ever been to Japan? 你到过日本吗?

Does she often have colds? 她常常感冒吗?

Did you ask her which to buy? 你问没问她该买哪一个?

二、陈述句变一般疑问句的方法

1.动词be的疑问式:动词be根据不同的时态和人称可以有am, is, are, was, were等不同形式,可用作连系动词(表示“是”、“在”等)和助动词(用于构成进行时态和被动语态等),但不管何种情况,构成疑问式时,一律将动词be的适当形式置于句首:句型:Be动词+主语~?

Is your father angry?你父亲生气了吗?

Yes,he is.是的,他生气了。

No,he isn't.不,他没生气。

Were the babies crying last night?(进行时)

昨天晚上这些孩子们一直在哭吗?

Yes,they were.是的,他们在哭。

No,they weren't.不,他们没哭。

Is English spoken all over the world?(被动语态)

全世界都说英语吗?

Yes,it is.是的。

No,it isn't.不。

初二期末英语语法知识点总结归纳

1.由that引导,由于that没有任何意义,也不充当任何句子成分。因此that在非正式文体中可以省略。这类宾语从句通常表达一种陈述意义。

e.g.He told me (that) he would go to Wuhan.

Tom says (that) he must study hard.

She told me (that) she was a student.

(1)如果由and连接两个并列的宾语从句时,第二个that则不能省略。

e.g.She said she liked English very much and that she didn’t like math at all.

(2)常接that引导的宾语从句的谓语动词有:believe, expect, explain, feel, hear, hope, imagine, prefer, promise, report, say, see, tell, think, understand, warn, wish等。

2.由连接代词或连接副词who, whose, what, which, when, where, how, why引导,含有“谁、什么、哪个、什么时候、什么地方、怎样、为什么”等特殊疑问意义。

e.g.Do you know who they’re talking about?

Can you tell me what they’re looking for?

I don’t know where she has gone.

I wonder how she can find us.

She didn’t tell me where her hometown was.

3.由从属连词whether和if引导,含有“是否,能否,对否,有否”等一般疑问意义。

e.g.She asked me if I could help her.

Jim wanted to know whether I had taken his English book.

Please tell me whether you can come or not.

在这类宾语从句中要注意两点:

(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.
