每年的中考試卷中，“句型轉換”題所占分值較大，是為了全面考查學生在初中階段所學的詞匯（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“句型轉換”就是先給一個完整的句子A，再根據括號內的要求（有時沒有明確，須自己觀察），在第二個句子B的空白處填上適當的詞來完成的句型轉換。
Ⅱ.題型分類
從形式上看，有如下幾種形式：①某一詞或詞組的轉換；②詞組與句子的轉換；③同義句型的轉換；④為糾正常犯語言錯誤而設計的題目。
從內容上看，此題型涉及的面較廣，主要有：①句子功能方面的轉換。包括陳述句（肯定與否定）、四種題疑問句、祈使句、感嘆句的轉換；②句子結構方面的轉換。即簡單句、復合句、并列句之間的轉換；③語態的轉換。即主動語態與被動語態之間的轉換；④常用句型與詞匯手段的轉換。
Ⅲ.具體分類如下
一、陳述句與疑問句、祈使句、感嘆句間的轉換
1、陳述句中肯定句變為否定句，大部分是用not來改變謂語結構，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。根據上下句的結構和詞的減少，來判斷變為哪一種形式的疑問句。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。根據所給的句子結構和單詞的詞性，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、同義句轉換。
根據上句，寫出一個意思相同（或相近）的下句，此類形式繁多，內容復雜，涉及面廣，歸類如下：
1、同義詞或詞組之間的轉換。（通常上下句時態保持一致）。
常見的同義詞或詞組有：(1)四個“花費”（spend-take-cost-take）；(2)三個“到達”（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”（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引導的時間狀語從句的轉換 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引導的條件狀語從句的轉化。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、現在完成時態中的一句多譯。在現在完成時態中，結束性動詞不能與時間段連用，必須改成相應的延續性動詞。常見的動詞轉換有：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、簡單句與復合句之間的轉換。
①含賓語從句的復合句與簡單句的轉換。例如：
A：I saw they were playing football on the playground.
B：I saw them playing football on the playground.
A：The teacher found that she was very clever.
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/副詞引導的賓語從句可轉化為“疑問句+不定式”結構。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引導的時間狀語從句可轉化為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+數詞+years old→at the age of+歲數
A：When he was twelve years old, Edison started writing his own newspaper.
B：At the age of twelve, Edison started writing his own newspaper.
③由so…that…引導的結果狀語從句可轉化為too…to do或…enough to do……例如：
A：The box is so heavy that I can’t carry it.
B：The box is too heavy for me to carry.
或：The box isn’t light enough for me to carry.
A：The child is so old that he can go to school.

⑤由because 引導的原因狀語從句可轉化為because of…例如：
