句型轉(zhuǎn)換口訣一 肯定句變一般疑問(wèn)句的四步曲1如果句子中有系動(dòng)詞（is, am ,are，was ,were），一般把系動(dòng)詞提前就可以。例如：She is a girl. - Is she a girl?2如果句子中有have(got), has(got)或情態(tài)動(dòng)詞can，就把它們（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 如果句子中沒(méi)有系動(dòng)詞，have(got), has(got)或情態(tài)動(dòng)詞can，先看時(shí)態(tài)，再來(lái)變一變。（1） 一般現(xiàn)在時(shí)，要用Do或Does來(lái)提問(wèn)，別忘后面動(dòng)詞回原形。例如：Tom goes to school by bus. - Does Tom goto school by bus?（2） 一般過(guò)去時(shí)，要用Did來(lái)提問(wèn)，別忘后面動(dòng)詞回原形。例如：He swamin water yesterday.- Did he swim in water yesterday? 4.要是遇到I或we，就要變成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?（注意大小寫(xiě)和標(biāo)點(diǎn)符號(hào)） 二肯定句變否定句三步曲1 如果句子中有系動(dòng)詞，直接在系動(dòng)詞后面加not。例如：She is a girl. - She is nota girl.2 如果句子中有，have(got), has(got)或情態(tài)動(dòng)詞can，直接在它們（have ,has和can）后面加not例如：They canmake cakes. - They can notmake cakes.
