初中英語句型轉(zhuǎn)換課件

1、句型轉(zhuǎn)換,DE,答題技巧,句型轉(zhuǎn)換是句子類別的轉(zhuǎn)換。該題的目的在于檢測(cè)學(xué)生運(yùn)用各種句型的表達(dá)能力。要求學(xué)生對(duì)所學(xué)的句子結(jié)構(gòu)和詞形的變化做到概念清楚，運(yùn)用準(zhǔn)確。,例1The little girl was so tired that she couldnt go farther.

2、ake good care of sb.,例2 It took him two hours to do these exercises yesterday. He _ two hours _ these exercises yesterday.,該句的句型是It takes sb sometime to do sth. 英語表達(dá)該意思的還有spendon句型。,例3 I must look after my sister well at home. I must _ _ _ _ my sister at home.,很明顯，這是兩個(gè)簡(jiǎn)單句之間的轉(zhuǎn)換，可用not strong enough來填空

3、。,例4They were tired, so they had a rest. They had a rest _ they were tired.,該句由并列句轉(zhuǎn)換為復(fù)合句，可用because來連接，表示因果關(guān)系。,例5He was too weak to carry the heavy box. He was _ _ _ to carry the heavy box.,從近年來的考題趨勢(shì)來看，句型轉(zhuǎn)換從單純測(cè)試語法知識(shí)向改變句子結(jié)構(gòu)填空，填詞后使句意不變或與要求相符的方向發(fā)展。其中許多屬于常用句型?？蓺w納如下：,2要熟悉常用句型的轉(zhuǎn)換規(guī)律。,例3We can fly to the moo
