陈述句和一般疑问句_疑问句
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:
He was late for school. Was he late for school? 他上学迟到了吗?
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:
He has anything to say. Does he have [Has he] anything to say?
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:
He has breakfast at home. Does he have breakfast at home?
③ 用作助动词构成完成时态,其疑问式总是将have等置于句首:
He left when you arrive. Has he left when you arrived?
3. 情态动词的疑问式:情态动词的疑问式通常是将情态动词置于句首:
She can speak English. Can she speak English?
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:

陈述句
1. 陈述句概念和基本类型
陈述句是用来陈述一件事或表达一种看法的句子。根据句中动词的类型和后接宾语的情况,通常又可将陈述句划分成一下五种形式:
类型 常见谓语动词 例句
主语+不及物动词
S+Vi sleep, walk, happen, come,
go, stay, arrive, laugh,等 The boy slept for a long time.
那个男孩睡了很久。
主语+及物动词+宾语 raise, call, meet, eat, leave等 Everyone knows the rule.
❖ 重点:陈述句的五大基本结构;陈述句的句型转换;祈使句的含义。
❖ 难点:陈述句的否定。
1. 否定大多时候是找原句中的助动词作文章,如果有助动词或be动词就否定在它们身上,若没有需要判断时态和人称,借助do,
did, does进行否定;
2. think等表观点词的否定转移;
3. either...or等关联词的全否定。 第 2 页
❖ 注:S:主语;Vi:不及物动词;Vt:及物动词;P:表语;O:宾语;C:宾语补足语。
2. 陈述句的否定结构
陈述句的否定一般否定在be动词、助动词或情态动词上,如:
I am not a doctor but a teacher.
我不是一名医生而是一个老师。
I haven’t finished my homework yet.
我还没完成我的作业。
I can’t do it by myself.
我不能独立完成。
在以下几种情况下,句子否定比较特殊,需要特别注意。
1). 含有have的否定句
(1). have作实意动词,表“有”或“吃”时,否定在前,根据时态用don’t, doesn’t或didn’t否定,如:
I didn’t have lunch today.
今天我没吃午饭。
