你好:
否定句:一般情况下,在be、have 、情态动词上加上not
例如:She is a teacher.
She isn't a teacher.
若没有这些动词,则加上助动词。
I like swimming.
I don't like swimming.
一般疑问句:把动词提前(be、have、情态)
She is a teacher.
Is she a teacher?
若没有这些动词,在句子前加上助动词。
I like swimming.
Do you like swimming?
否定句:一般情况下,在be、have 、情态动词上加上not
例如:She is a teacher.
She isn't a teacher.
若没有这些动词,则加上助动词。
I like swimming.
I don't like swimming.
一般疑问句:把动词提前(be、have、情态)
She is a teacher.
Is she a teacher?
若没有这些动词,在句子前加上助动词。
I like swimming.
Do you like swimming?

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:
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 making 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?
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’t。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’t。人称不变化。实义动词不能直接加否定词,须加助动词doesn’t(第三人称单数)、don’t、didn’t。例如:I am English teacher. 改成:I am not (aren’t也可以)English teacher.She has got some apples. 改成:She hasn’t(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:Su yang often plays football.可以改成:Su yang doesn't play football (at all).Su yang seldom plays football.Su yang never plays football.
Some改成否定句一般也要改成any。
