英语句子怎么改否定句和一般疑问句?~

1、改否定句:
先找句子的谓语动词,确定时态,找好这个时态的助动词(通常为do,does,did,will,shall,have,has,had还有动词be),这些词后面都可以加not来构成否定句。
2、改一般疑问句:
可以在后面直接加not的词(如时态助动词和情态动词)都可以放在句首构成一般疑问句。
变成特殊疑问句:在一般疑问句前面加上特殊疑问词即可。

一般疑问句:
以be动词, have /has/do等助动词、can/may等情态动词开头,以yes或no来回答的问句。 它的基本结构是:Be/Have /Has/Did等助动词(包括情态动词)+主语+谓语(包括表语)+?回答常用简略回答。
1、谓语动词是be动词、助动词、情态动词时,只要直接把这些词置于句首,句末改成问号。
2、谓语动词是行为动词时,必须在句首加上助动词Do、Does(三单)、Did(过去式)加上这些助动词后,句子中谓语动词必须用原形。

1. I don't want to go to the Great Wall. Do you want to go to the Great Wall? 2.They don't like green tea. Do they like green tea? 3.Jane didn't study in a high school. Did Jane study in a high school? 4.He didn't drive a bus. Did he drive a bus?

1. 由系动词am,is,are构成的句子:变一般疑问句时把am,is,are提到句子的前面,句尾用问号即可。变否定句时直接在am,is,are后面加not即可。例如:
肯定句:He is a student.
一般疑问句: Is he a student?
否定句: He is not a student.
反问句: He is a student, isn't he?
He isn't a student, is he?
画线提问: 对he提问: Who is a student?
对 a student 提问: What is he? or What does he do?

2. 由情态动词can, may, should等构成的句子: 变一般疑问句时把can,may,提到句子的前面,句尾用问号即可.变否定句时直接在can,may,后面加not即可. 例如:
肯定句: She can swim.
一般疑问句: Can she swim?
否定句: She can not swim.
反问句: She can swim, can't she?
She can not swim, can she?
画线提问: 对she提问: Who can swim?
对swim提问: What can she do?

3. 由行为动词构成的句子: 需要加助词do或does. 变一般疑问句时把do/does放在句子前面. 例如:

肯定句: They play football after school.
一般疑问句: Do they play football after school?
否定句: They don't (do not) play football after school.
反问句: They play football after school, don't they?
They don't play football after school, do they?
画线提问: 对they提问: Who play football after school?
对play football提问: What do they do after school?
对after school提问: When do they play football?

帮我个忙,用就是用反问句写出yes...或no... 帮个忙吧!

否定句:* 有be动词的句子,直接在be动词的后面加not 如:
she is not a teacher.
they were not watching tv.
* 没有be动词的句子,要用到助动词来完成否定 如
she doesn't like english.
they didn't want to watch tv.

疑问句: 有be动词的句子,将be动词提前,其余照抄,用问号结尾 如:
is she a teacher?
were they watching tv?

没哟be动词的句子,要用到助动词来构成疑问语序, 如:
does she want to be a teacher?
did they watch tv last night?
