初中英語(yǔ)要如何學(xué)習(xí)句型轉(zhuǎn)換的句子呢?下面是學(xué)習(xí)啦小編為大家?guī)?lái)的關(guān)于中考英語(yǔ)句型轉(zhuǎn)換口訣，供大家參考。
中考英語(yǔ)句型轉(zhuǎn)換口訣：
句型變化很簡(jiǎn)單， / 先把句中動(dòng)詞看：/ be may must will can，/ 否定句not加后邊。/ 一般問(wèn)句也不難，/ 助情動(dòng)詞放句前;/ 兩種回答yes no，/ 句首動(dòng)詞人后面。/ 沒(méi)有現(xiàn)成怎么辦?/ do does did來(lái)相伴，/ 三單式過(guò)去要還原。/ 特殊問(wèn)句更簡(jiǎn)單，/ 疑問(wèn)詞后跟一般。/ 事物職業(yè)等what，/ who人where問(wèn)地點(diǎn)，/ whose誰(shuí)的所有權(quán)。/ 數(shù)量how many復(fù)后邊，/ how much不可數(shù)和價(jià)錢。/ why問(wèn)原因慢慢談，/ what time when時(shí)間， / how old歲數(shù)多少年?/ how be人身永康健!
中考英語(yǔ)句型轉(zhuǎn)換口訣例析：
上述口訣表明：句型變化的關(guān)鍵是識(shí)別和取決于句中的動(dòng)詞。如果句中有現(xiàn)成的 be ，have，used，may ，must ，will ，can等助動(dòng)詞或情態(tài)動(dòng)詞，則在其后直接加上not即構(gòu)成否定句;將其提于句首則成為一般疑問(wèn)句，在簡(jiǎn)略回答中，除there be句型外，在yes或no后邊一般要使用“人稱代詞主格+助動(dòng)詞或情態(tài)動(dòng)詞成分”，其中的助動(dòng)詞或情態(tài)動(dòng)詞應(yīng)該與問(wèn)句保持一致。
(1) That’s her grandfather over there(改為否定句和一般疑問(wèn)句并回答)。根據(jù)口訣，我們發(fā)現(xiàn)句中有現(xiàn)成的 be動(dòng)詞is ，不需要其他的助動(dòng)詞來(lái)協(xié)助，故本句的否定句為：That’s not her grandfather over there;一般疑問(wèn)句及回答為：Is that her grandfather over there?Yes，he is;/ No，he isn’t.
(2) Tom used to read Chinese histories.(改為否定句和一般疑問(wèn)句并回答)，句中的used是一個(gè)突破口，故否定句為Tom used not to read Chinese histories;一般問(wèn)句和回答為Used Tom to read Chinese histories ?Yes，he used;/ No，he usedn’t. 但根據(jù)傳統(tǒng)習(xí)慣，本句也可以將used視為行為動(dòng)詞 use的過(guò)去式，故其否定句和一般疑問(wèn)句及回答分別是Tom didn’t use to read Chinese histories和Did Tom use to read Chinese histories ?Yes，he did;No，he didn’t .
“沒(méi)有現(xiàn)成怎么辦”指的是句中沒(méi)有be ，have，used，may ，must ，will ，can等助動(dòng)詞或情態(tài)動(dòng)詞的情況。如果沒(méi)有，則要根據(jù)動(dòng)詞的時(shí)態(tài)和形式借用相應(yīng)的助動(dòng)詞 do(幫助行為動(dòng)詞原形)，does(幫助行為動(dòng)詞的第三人稱單數(shù)形式)或 did(幫助行為動(dòng)詞的過(guò)去時(shí)形式)來(lái)協(xié)助構(gòu)成否定句或問(wèn)句;“三單式過(guò)去要還原” 指的是在用 does或 did協(xié)助構(gòu)成否定句或問(wèn)句后，原句中的動(dòng)詞第三人稱單數(shù)形式或過(guò)去式必須改為動(dòng)詞原形，否則就犯了重復(fù)的錯(cuò)誤，這也是許多學(xué)生慣犯的一種錯(cuò)誤，令老師頭疼。
例(3) Li Ping goes shopping with her mother on Sundays(改為否定句和一般疑問(wèn)句并回答)。句中有三單式goes , 立刻就聯(lián)想到does的助動(dòng)詞功能，故本題的答案分別為L(zhǎng)i Ping doesn’t go shopping with her mother on Sundays和Does Li Ping go shopping with her mother on Sundays?Yes，she does;/ No，she doesn’t. 但要注意，do和have還有行為動(dòng)詞的功能，這是學(xué)生在做句型轉(zhuǎn)換練習(xí)時(shí)遇到的又一難題，誤將句中的do或have視為助動(dòng)詞而導(dǎo)致錯(cuò)誤的結(jié)果。
如(4) My brother does his homework in the evening(改為否定句和一般疑問(wèn)句)，能夠想到正確答案My brother doesn’t do his homework in the evening和Does your brother do his homework in the evening?的同學(xué)為數(shù)不多。
(5) Jim’s parents have lunch in the factory(改為否定句和一般疑問(wèn)句并回答)，許多學(xué)生就錯(cuò)解為Jim’s parents haven’t lunch in the factory和Have Jim’s parents lunch in the factory? Yes , they have ; / No , they haven’t . 而本句中的have是行為動(dòng)詞“吃” 的意思，正確做法應(yīng)該為Jim’s parents don’t have lunch in the factory和 Do Jim’s parents have lunch in the factory? Yes , they do ;/ No, they don’t .
“疑問(wèn)詞后跟一般”意思是特殊疑問(wèn)句由“疑問(wèn)代詞或疑問(wèn)副詞+一般疑問(wèn)句”構(gòu)成，只要學(xué)生掌握了一般疑問(wèn)句的轉(zhuǎn)換要點(diǎn)和各類疑問(wèn)代詞或疑問(wèn)副詞的意義和功能，特殊疑問(wèn)句以及其他的句型變化就會(huì)迎刃而解。例如，口訣中的“事物職業(yè)等what”，其意義功能指的是what用來(lái)對(duì)事物、職業(yè)、姓名、顏色等提問(wèn)
如(6) My e-mail address is cindyj@pep.com.cn(對(duì)畫線部分提問(wèn))為What is your e-mail address? “who人where問(wèn)地點(diǎn)”是指who用于對(duì)人物、身份、關(guān)系等句子成分提問(wèn)而where用于對(duì)地點(diǎn)狀語(yǔ)提問(wèn)
例(7) Kate’s shoes are under the bed(對(duì)畫線部分提問(wèn))為Where are Kate’s shoes? 而表面看起來(lái)很相似的另一個(gè)句子The shoes under the bed are Kate’s(對(duì)畫線部分提問(wèn))，學(xué)生做起來(lái)就又感到納悶了，是用where還是which提問(wèn)呢?其納悶的根本原因是沒(méi)有弄懂畫線部分under the bed在本句中是后置定語(yǔ)，故本題的正確解答應(yīng)為Which shoes are Kate’s? “數(shù)量how many復(fù)后邊”即對(duì)數(shù)量提問(wèn)用how many，后面接復(fù)數(shù)形式
例如(8) There are fifty-two students in Tom’s class(對(duì)畫線部分提問(wèn))為How many students are there in Tom’s class?How many后邊接的是復(fù)數(shù)形式students和are . how much用于對(duì)不可數(shù)名詞或價(jià)錢提問(wèn)
如(9) The black pants are (對(duì)畫線部分提問(wèn))為How much (money) are the black pants? 當(dāng)然，本句也可以表示為What’s the price of the black pants? “how be人身永康健”即How be sb.? 一般用于詢問(wèn)某人的身體健康狀況，如(10) ——How are you?—— I’m well, thank you .
