句型轉(zhuǎn)換解題技巧點(diǎn)撥

句型轉(zhuǎn)換綜合考查學(xué)生對(duì)課本知識(shí)點(diǎn)的理解、記憶和靈活運(yùn)用的能力，它能較好地反映出同學(xué)們對(duì)英語基本句型的熟悉和運(yùn)用程度。其考查的主要形式有三種：

一、 按要求轉(zhuǎn)換句型

做這種題，首先應(yīng)明確每一種時(shí)態(tài)、語態(tài)的語法結(jié)構(gòu)，疑問句及否定句的構(gòu)成，當(dāng)然還要掌握一些特殊用法。

1.肯定句、否定句、疑問問、感嘆句、祈使句之間的轉(zhuǎn)換

①M(fèi)y father put his bike under the tall tree.(改為否定句)(2006年宿遷市)

My father ______ ______ his bike under the tall tree.(didn’t put)

②Miss Green regards her pet as her good friend.(改為一般疑問句)(2006年甘肅省)

③Most information on the Internet is in English，______ ______ ?(改為反意疑問句) (2006年甘肅省)(isn’t it)

④People on the hill are working very hard. (改為感嘆句)(2006年蘇州市)

______ ______ people on the hill are working!(How hard)

2.簡(jiǎn)單句與復(fù)合句之間的轉(zhuǎn)換

3.主動(dòng)語態(tài)變?yōu)楸粍?dòng)語態(tài)

①Students can’t take magazines out of the reading-room.(改為被動(dòng)語態(tài))(2006年重慶市)

②The villagers built a watchtower on the top of the hill， so they could find the fire in the forest early. (改為被動(dòng)語態(tài))(2006年山東省)

A watchtower ______ ______ on the top of the hill， so the fire in the forest

______ early.(was built， could be found)

二、 對(duì)劃線部分提問

這類題要求把陳述句變成特殊疑問句。首先根據(jù)劃線部分確定疑問詞，然后變成一般疑問句，應(yīng)注意時(shí)態(tài)、助動(dòng)詞的變化。

疑問詞的種類有：①疑問代詞：who，whom，what，whose，which。②疑問副詞：when，where，how，why。③短語：how many，how much，how long，how far，how soon，how often，how many times，how old，what colour等。疑問代詞在句子中作主語或主語的定語時(shí)，其句子結(jié)構(gòu)與陳述句相同，不加助動(dòng)詞；疑問代詞在句子中作其他成分時(shí)，都必須放在句首。如：

①Kate usually goes to her office by bike.(對(duì)劃線部分提問)(2006年濟(jì)南市)

______ ______ Kate usually ______ to her office?(How does， go)

②I collect toys because they are beautiful. (對(duì)劃線部分提問)(2006年重慶市)

______ ______ you collect toys?(Why do)

三、同義句轉(zhuǎn)換

一般來說，這類題目有以下四種情況：

1．簡(jiǎn)單句之間的轉(zhuǎn)換

簡(jiǎn)單句之間的轉(zhuǎn)換通常有：用同義詞(詞組)、反義詞(詞組)替換相關(guān)的詞語，或用意思相同的句型替換。如：

①M(fèi)y parents prevent me from playing computer games.(改為同義句)(2006年合肥市)

My parents don’t ______ me ______ play computer games.(allow， to)

②Alice didn’t know how she could draw horses well. (改為同義句) (2006年重慶市課改實(shí)驗(yàn)區(qū))

Alice didn’t know how ______ ______ horses well.(to draw)

2．復(fù)合句之間的轉(zhuǎn)換

復(fù)合句之間的轉(zhuǎn)換通常用不同的詞改寫或改變句子結(jié)構(gòu)。如：

①Ann has decided to be a vet when she grows up. (改為同義句)(2006年桂林市)

Ann has ______ a ______ to be a vet when she grows up.(made， decision)

②Yao Ming received thousands of letters from his fans after his leg was broken. (改為同義句)(2006年鹽城市)

Yao Ming ______ ______ thousands of his fans after his leg was hurt.(heard from)

3．復(fù)合句轉(zhuǎn)換成簡(jiǎn)單句

復(fù)合句轉(zhuǎn)換成簡(jiǎn)單句多用動(dòng)詞不定式、介詞短語替換從句或用相同的句型替換。如：

①It is three years since I became a middle school student. (改為簡(jiǎn)單句)(2006年孝感市)

I ______ a middle school student three years ______ .(became， ago)

②If you work hard， you will do well in physics. (改為簡(jiǎn)單句)(2006年孝感市)

______ ______ ， and you will do well in physics.(Work hard)

4．并列句或兩個(gè)簡(jiǎn)單句轉(zhuǎn)換成復(fù)合句

這類題目一般運(yùn)用并列連詞、不定式或一些關(guān)聯(lián)詞。

①“Don’t spend too much time on computer games.” Mr. Wang said to Tony.(改寫句子，句意不變)(2006年濟(jì)南市)

Mr. Wang ______ Tony ______ ______ spend too much time on computer games.(told， not to)

②Be quick， or you will be late for school again. (改寫句子，句意不變)(2006年泰州市)

______ ______ be quick， you will be late for school again.(If don’t)

【技巧點(diǎn)撥】

1.注意時(shí)態(tài)。

2.句子的成分不變。原句的句子在改變句型時(shí)仍不可缺少，否則句子不完整，但有一個(gè)例外，在陳述句改為感嘆句時(shí)，要增加句子成分，感嘆詞what和how分別為按句子的要求而增加的定語或狀語，句子其他成分不變。

3.反復(fù)推敲，確保無誤。改變后要看看意思是否與要求相符，有沒有語法和習(xí)慣用法方面的錯(cuò)誤。
