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)

全世界都说英语吗?
Yes,it is.是的。
No,it isn't.不。
2.动词have的疑问式:动词have根据不同的时态和人称可以有have, has, had等形式,可以用作实意动词和助动词,分以下情况讨论:
①用作实意动词表示状态,如表示拥有、患病或用于have to表示“必须”等,在构成构成式时可以直接将have, has, had置于句首,也可根据情况在句首使用do, does, did:
Does he have [Has he] anything to say? 他有什么话要说吗?
Do you have [Have you] to leave so soon? 你必须这么早走吗?
Did you have [Had you] any friends then? 他当时有朋友吗?
②用作实意动词表示动作,如表示“吃(=eat)”、“喝(=drink)”、“拿(=take)”、“收到(=receive)”、“度过(=spend)”等,构成疑问式时不能将have提前至句首,而应在句首使用do, does, did:
Does he have breakfast at home? 他在家吃早餐吗?
Did you have a good time at the party? 你在晚会上玩得高兴吗?
③完成时的一般疑问句
句型:Have(Has)+主语+动词的过去分词+~?

No,I haven't.不。
过去完成时的一般疑问句

words before he came here?
他来这里以前就已经学了大约两千个单词了吗?
Yes,he had.是的。
No,he hadn't.不。

Yes,I can.是的,可以。
No,I can't.不,不可以。
Can you speak English? 你会说英语吗?

4.实意动词的疑问式:一般实意动词的疑问式,通常应根据不同时态和人称在句首加助动词do, does, did等:
句型:Do(Does,Did)+主语+动词原形~?

Does the boy like dancing? 这男孩喜欢唱歌吗?
Did you see the film last night? 你昨晚看了这部电影吗?
Did he do morning exercises yesterday?
昨天他做早操了吗?
Yes,he did.是的,他做了。
No,he didn't.不,他没做。
特殊疑问句
用疑问词引导的疑问句叫做特殊疑问句。回答特殊疑问句时不能用yes或no。用降调。为了便于理解、掌握特殊疑问句,我们把疑问词分为三类:
疑问代词:what,who,Which,whose,whom
疑问副词:when,where,why,how
疑问形容词:what(which,whose)+名词
一、疑问代词的用法
1.what引导的疑问句
此类疑问句可以对主语、表语和宾语提问。

这个问题可以有两种回答:

在口袋里有一个蛋。
b:An egg is(in it).
一个蛋(在里面)。
There are a lot of chairs in it.
=A 1ot of chairs are in it.有许多椅子。
注意
回答此句型的问题时,答句的单复数根据实际情况而定。
B.对宾语提问
What did you buy?你买了什么?
C.对表语提问
What is this?这是什么?
It's a bench.这是一条长凳。
What is your mother?你妈妈是干什么的?
2.Who,whom,whose引导的疑问句
此类疑问句可以对主语、表语和宾语提问。
Who broke the window?(对主语提问)
谁打破了窗户?
who可以对主语和表语提问。whom是who的宾格,对宾语提问,但在口语中who可以代替whom。
Li Ming did.李明打破的。
Who is that woman?(对表语提问)
那个女人是谁?
She is my mother.她是我妈妈。(关系)
或者:She is Rose.她是罗思。(姓名)
二、疑问形容词的用法
what,which,whose后面跟上名词时,这三个疑问词起形容词作用。
What sports do you like?(对宾语提问)

右边的那一张是我拍的。
三、疑问副词的用法
句型:疑问副词+一般疑问句的语序~?
(疑问副词在句中作状语,所以它们不可能对主语提问)
when引导的疑问句:询问时间
When were you born?你何时出生?
(I was born)on June 5,1962.
我是1962年6月5日出生的。
