一般疑问句否定句特殊疑问句的改法

1、简易英语语法动词的分类Be 动词：is, am, are, was, were助动词： do, does, did, has, have, had动词 情态动词： can, must, may, should,等-实义动词： run, eat, play, like, 等等。陈述句改为一般疑问句的改法：一般疑问句：以be动词、助动词、情态动词为句首，句末有问号（？）的句子。例如：Is she a doctor.她是一名医生吗？Has she got any grapes?她有些葡萄吗？（这里的has是助动词，got（ get的原形）是有的意思。Can you fly?你会飞吗？当句子中的谓语只

2、有实义动词，没有be动词、助动词、情态动词的时候，句子变一般疑问句时要加do、does、did （do、dose的过去式）其中之一。如： The fox likes grapes.句子的 谓语没有be动词、助动词、情态动词，只有 likes， like是实义动词，因此，句首要加助动 词；又因为the fox是第三人称单数，句首的助动词就用 does.句子的就变成 Does the fox like grapes?注意原来likes中的s,要删除。一般疑问句主语和 be动词、助动词、情态动词倒装。没有这三类词时要加助动词。如：a doctor.a doctor?She usually goes

3、to school at seve n.Does she usually go to school at seven?记住：实义动词始终在主语的后面。注意：述句（句子后面只有句号的句子）给成一般疑问句时，一般情况下，还要把第一人称I、we、my、our 改成 you、your，把 some 变成 any。如:I have got some apples.I am mak ing my aeropla ne.变成:got any apples?mak ingaeropla ne?We are watching TV.变成：Are you watching TV?还要注意：如果 has have、

4、had、do、does、did后面是名词时，has、have就不是助动词了, 他们是实义动词。改一般疑问时不能提前（一般情况下，所有实义动词都不能提到主语前面） 要根据时态加助动词 do、does、did。女口： She has breakfast everyday.练习，把下列的句子改成一般疑问句。1. His father is an En glish teacher.2.

9、s?19. Has you got a bird?20. Have Kitty and Tom got a dog?21. Do you have breakfast every morning?这里的 have 是吃的意思。22. Do they do their homework after school?do their homework 中的 do 是做的意思。否定句的改法首先要认清“否”就是“不”的意思，在英语中就是not或not的省略形式n'。否定句是在be动词、助动词、情态动词后加not或not的缩略形式n'。人称不变化。实义动词不能直接加否定词，须加助动词doe

10、s nt （第三人称单数）、don ' did n't。例如：I am English teacher. 改成：I am not （aren ' 也可以） English teacher. She has got some apples. 改成： She hasn ' （ has not 也可以）got any apples.注意：一些否定词 hardly （几乎不）few （很少可数）little （很少不可数）nothing （没有） none （没有人或物）等也是否定词。含有此类否定词的句子也是否定句。am not的否定缩略形式是aren 't如：
