每年的中考試卷中，“句型轉(zhuǎn)換”題所占分值較大，是為了全面考查學(xué)生在初中階段所學(xué)的詞匯（同義或反義）、短語、句型和語法等方面的知識及其它的之間的靈活運用能力。
Ⅰ.題型介紹
所謂“句型轉(zhuǎn)換”就是先給一個完整的句子A，再根據(jù)括號內(nèi)的要求（有時沒有明確，須自己觀察），在第二個句子B的空白處填上適當(dāng)?shù)脑~來完成的句型轉(zhuǎn)換。
Ⅱ.題型分類
從形式上看，有如下幾種形式：①某一詞或詞組的轉(zhuǎn)換；②詞組與句子的轉(zhuǎn)換；③同義句型的轉(zhuǎn)換；④為糾正常犯語言錯誤而設(shè)計的題目。
從內(nèi)容上看，此題型涉及的面較廣，主要有：①句子功能方面的轉(zhuǎn)換。包括陳述句（肯定與否定）、四種題疑問句、祈使句、感嘆句的轉(zhuǎn)換；②句子結(jié)構(gòu)方面的轉(zhuǎn)換。即簡單句、復(fù)合句、并列句之間的轉(zhuǎn)換；③語態(tài)的轉(zhuǎn)換。即主動語態(tài)與被動語態(tài)之間的轉(zhuǎn)換；④常用句型與詞匯手段的轉(zhuǎn)換。
Ⅲ.具體分類如下
一、陳述句與疑問句、祈使句、感嘆句間的轉(zhuǎn)換
1、陳述句中肯定句變?yōu)榉穸ň洌蟛糠质怯胣ot來改變謂語結(jié)構(gòu)，但也有借用否定意義的詞，如nothing, nobody, none, neither, little, few, never, hardly等，例如：：
A：Tom does well in maths.
B：Tom doesn’t do in maths.
A：He has much to do.
B：He has nothing to do.
A：All of my classmates like art.
B：None of my classmates likes art.
2、改為疑問句。根據(jù)上下句的結(jié)構(gòu)和詞的減少，來判斷變?yōu)槟囊环N形式的疑問句。例如：
A：My brother often has breakfast at school.
B： Does your brother often have breakfast at school?
A：Tom’s already weak in English.
B：Tom’s already weak in English, isn’t he ?
A：The red light changes every two minutes.
B：How often does the red light change?
3、改為感嘆句。根據(jù)所給的句子結(jié)構(gòu)和單詞的詞性，來確定使用哪一種感嘆句的形式，例如：
A：This is an interesting book.
B：What an interesting book this is!
或 How interesting this book is!
二、同義句轉(zhuǎn)換。
根據(jù)上句，寫出一個意思相同（或相近）的下句，此類形式繁多，內(nèi)容復(fù)雜，涉及面廣，歸類如下：
1、同義詞或詞組之間的轉(zhuǎn)換。（通常上下句時態(tài)保持一致）。
常見的同義詞或詞組有：(1)四個“花費”（spend-take-cost-take）；(2)三個“到達(dá)”（get to-reach-arrive in/at）；(3)四個“收到…來信”（hear from-get a letter from-receive a letter from-have a letter from）；(4)兩個“擅長于…”（be good at -do well in）；(5)兩個“有空”（be free-have time）；(6)三個“入睡”（go to sleep-get to sleep-fall asleep）；(7)兩個“玩得開心”（enjoy oneself-have a good time）；(8)“給…打電話”（call sb-telephone sb-ring sb. a call-make a telephone to sb.）(9)“飛往…”（fly to…-go to…by air/plane）(10)“自學(xué)”（teach oneself-learn…by oneself）(11)在…方面幫助help…with…-help… (to)do…(12)在…差be weak in…-do badly in…(13)能/會…can-be able to(14)更喜歡…like…better than…-prefer…to…(15)充滿了…be full of…-be filled with…(16)放棄干…give up doing…-stop doing…(17)不再… no longer-not …any longer(18)照顧/保管 take care of…-look after(19)展覽 on show-on display(20)阻止…干…stop…from doing-keep/prevent…from doing…(21)由于 thanks to-because of…(22)舉手hands up-put up one’s hands(23)最后，終于at last-in the end(24)與…不同 be different from…-be not the same as…(25)從…借入… borrow…from…-lend…to…(26)乘公汽/火車/的士 go to…by bus/train/taxi-take a bus /train/taxi to…(27)乘自行車去… go to…by bike-ride a bike to…(28)為…感到自豪 be proud of…-be the pride of…(29)步行去… walk to…-go to…on foot (30)獨自地by oneself -alone等。例如：
A：The children had a good time in the park.
B：The children enjoyed themselves in the park.
2、同義句型之間的轉(zhuǎn)化。常見的同義句型有①It seems that 從句→Somebody seems（to be）+adj/n ②It’s kind of sb. to do…→Somebody is kind to do… ③What does…mean?→What do you mean by…? 或What’s the meaning of…?④There is something wrong with…→Something is wrong with… ⑤not…until…與when/after/before引導(dǎo)的時間狀語從句的轉(zhuǎn)換 ⑥What’s wrong with…?→What’s the matter with…? ⑦How is…?→What’s…like…?⑧How do you like…?→What do you think of?⑧It’s time that…→It’s time for sb. to do…⑨It’s said that…→People say that…⑩Can I help you? →What can I do for you?
例如：
A：I went to bed after I finished my homework.
B：I didn’t go to bed until I finished my homework.
3、if引導(dǎo)的條件狀語從句的轉(zhuǎn)化。例如：
A：If it doesn’t rain tomorrow, they’ll go to the park.
B：Unless it rains tomorrow, they’ll go to the park.
A：If you don’t hurry, you’ll be late.
B：Hurry up, or you’ll be late.
A：Fish can’t live if there is no water.
B：Fish can’t live without water.
4、現(xiàn)在完成時態(tài)中的一句多譯。在現(xiàn)在完成時態(tài)中，結(jié)束性動詞不能與時間段連用，必須改成相應(yīng)的延續(xù)性動詞。常見的動詞轉(zhuǎn)換有：buy-have, borrow-keep, die-be dead, open-be open, join-be in+組織/be a +成員, begin-be on, leave-be away from, close-be closed, arrive in/ get to/ come/go to-be in/at, finsh-be over, go to sleep-be asleep，get up-be up.
例如：The old man died five months ago.
The old man has been dead since five months ago.
The old man has been dead for five months.
It’s five months since the old man died.
Five months has passed since the old man died.
5、簡單句與復(fù)合句之間的轉(zhuǎn)換。
①含賓語從句的復(fù)合句與簡單句的轉(zhuǎn)換。例如：

B：The teacher found her very clever.
A：He found that it was hard to learn English well.
B：He found it hard to learn English well.
A：We are sure that we will win to first match.
B：We are sure to win to first match.
由疑問代詞/副詞引導(dǎo)的賓語從句可轉(zhuǎn)化為“疑問句+不定式”結(jié)構(gòu)。例如：
A：Could you tell me how I can get to the railway station?
B：Could you tell me how to get to the railway station?
A：We don’t know what we should do next.
B：We don’t know what to do next.
②由when/after/before/while/since/until引導(dǎo)的時間狀語從句可轉(zhuǎn)化為when/after/before/while/sine/until + doing…
例如：
A：They went home after they finished their work.
B：The went home after finishing their work.
A：Mr Smith has taught English since he came to China.
B：Mr Smith has taught English since coming to China.
When sb. +be+數(shù)詞+years old→at the age of+歲數(shù)

⑤由because 引導(dǎo)的原因狀語從句可轉(zhuǎn)化為because of…例如：
A：We didn’t go to the park because it rained.
B：We didn’t go to the park because of the rain.
⑥定語從句可以轉(zhuǎn)化為介詞短語或分詞短語。例如：
