1、1一般疑问句、否定句、特殊疑问句的改法(150308)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
2、。Can you fly? 你会飞吗？当句子中的谓语只有实义动词，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
3、。如：She is a doctor. She usually goes to school at seven.Is she a doctor? 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 making my aeroplane.变成：Have you got any apples? Are you makin
4、g your aeroplane?We are watching TV. 变成：Are you watching TV?还要注意：如果 has、have、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。如：She has breakfast everyday. Does she have breakfast everyday?练习，把下列的句子改成一般疑问句。21. His father is an English teacher.
5、 2. These cats are crying. 3. They can swim. 4. I like to read English. 5. I go to school on foot. 6. He likes English. 7. His father goes to work by bus. 8. He is crying under the tree. 9.

7、ot a dog.21.I have breakfast(早饭) every morning.322.They do their homework after school(放学).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 nt。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 nt。人称不变化。实义动词不能直接加否定词，须加助动词 doesnt（第三人称单数）、dont、didnt。例如：I am English teacher. 改成：I am not （arent 也可以） English teacher.Sh
8、e has got some apples. 改成：She hasnt（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 arent如：Su yang often plays football.可以改成：Su yang doesnt play football (at all).Su yang seldom plays football.Su yang never plays fo
9、otball.Some 改成否定句一般也要改成 any。练习，将下列句子改为否定句。1. His father is an English teacher. 2. These cats are crying. 3. They can swim. 4. I like to read English. 5. I go to school on foot. 6. He likes English. 7. Mrs. Li and Kitty watch television at night. 8. I do my homework after school.9.I have got some gra
10、pes.10.Toms got a bird.11.I have breakfast(早饭) every morning.412.They do their homework after school(放学).13. Kitty often goes to the cinema（去看电影）.特殊疑问句的改法：以特殊疑问词开头，对陈述句中的某一部分提出疑问 / 进行发问, 回答时针对问句中的代词和副词来回答，不用 yes 或 no,的句子叫特殊疑问句。特殊疑问句是以特殊疑问词为句首，句末有问号的句子。特殊疑问词包括 what（什么）、when（什么时候）、who（谁）、which（哪个）、whe

12、几次）、how old（多大，年龄大小）、how far（多远，距离）、how many/much（多少数量，many+复数，much+不可数）等。注意：特殊疑问句和一般疑问句一样，一般情况下要有倒装。如：I am reading.What are you doing?但如果对主语的提问，则主语谓语不倒装。如：Kitty likes grapes.Who likes grapes?What 是对名词的提问。Whats your nam?
