句型转换口诀
一.肯定句变一般疑问句的四步曲
1如果句子中有系动词(is, am ,are,was ,were),一般把系动词提前就可以。
例如:She is a girl. ----→Is she a girl?
2如果句子中有have(got), has(got)或情态动词can,就把它们(have ,has 和can)提前就可以。
例如:They canmake cakes. -----→ Can they make cakes?
She has got a dog. -------→ Hasshe got a dog?
3 如果句子中没有系动词,have(got), has(got)或情态动词can,先看时态,再来变一变。
(1)一般现在时,要用Do或Does来提问,别忘后面动词回原形。
例如:Tom goes to school by bus. -------→Does Tom goto
school by bus?
(2)一般过去时,要用Did来提问,别忘后面动词回原形。
例如:He swamin water yesterday.-----→Did he swim in water yesterda y?
4.要是遇到I或we,就要变成you ( my---your, our----your)
例如:(1)I am a teacher.----→Am I a teacher?---→____ you a teacher?
---→Are you a teacher?
(2)This is my mother.--→Is this your mother?
(注意大小写和标点符号)
二.肯定句变否定句三步曲
1.如果句子中有系动词,直接在系动词后面加not。
例如:She is a girl. ----→She is nota girl.
2.如果句子中有,have(got), has(got)或情态动词can,直接在它们(have ,has和can)后面加not
例如:They canmake cakes. -----→They can notmake cakes.
She has got a dog. -------→She has not got a dog.
3.如果句子中没有系动词,have(got), has(got)或情态动词can,先看时态,再来变一变。
(1)一般现在时,要用don’t或doesn’t来否定,别忘后面动词回原
形。
Tom goes to school by bus. -------→Tom doesn’t goto school by
bus.
(2)一般过去时,要用didn’t来否定,别忘后面动词回原形。
He swamin water yesterday.-----→He didn’t swim in water
yesterday
三对划线部分提问(即变特殊疑问句)三步曲
1.先选好特殊疑问词
2.再在疑问词后面,加上一般疑问句。
3.去掉划线部分,检查提问和回答是否能对应。(如果划线是动词短语,有时需要加个词)
例如: He plays computer games every day.
(1)选疑问词What
(2)What加上一般疑问句does he play computer games every day?
(3)去掉划线部分what does he play every day?
再如:He plays computer games every day.
(1)选疑问词What
(2)What加上一般疑问句does he play computer games every day?
(3)去掉划线部分what does he every day?
(4)What does he doevery day? (如果划线是动词短语,有时需要加个词)
再如:He is playing computer gamesnow.
(1)选疑问词What
(2)What加上一般疑问句is he playing computer gamesnow ?
(3)去掉划线部分what is he now?
(4)What is he doing now? (如果划线是动词短语,有时需要加个词)
