就是指名词同义词替换进行句子转换. 同义句转换是英语句型转换的一种重要形式,也是中考命题的一个热点.该题型主要考查同学们对英语词汇、句型的掌握情况和灵活运用的能力.其特点是涉及面广、语言点多、方式灵活、要求较高、难度较大. 一、用同义词(近义词)或词组改写 做此题型时,我们可以采用“词语替代法”,此法是指用词性相同的同义词、近义词或同义词组对原句的某些成分进行简单的替代,而句子结构保持不变.因此,我们在学习过程中要掌握尽可能多的同义词(组),如:be able to,can;arrive in(at),reach,get to;be good at,do well in;have a good time,enjoy oneself;look after,take care of;over,more than等等.具体运用时,还要注意它们在句中的位置,形式与转换后句中其他部分的相应变化.例如: 1.Every day,Wang Zhizhi receives emails from thousands of basketball fans. Every day,Wang Zhizhi _______ _______ thousands of basketball fans. 2.They will get to London in four days. They will _______ _______ London in four days. 答案:1.hears from 2.arrive in 二、运用反义词或词组改写 英语中有些反义词(组)具有非此即彼的排它性.因此其否定式与其对应的反义词(组)同义.如:same与different ,not same= different ,not different=same ,所以此类反义词(组)的否定式可以用于同义转换.另外,用反义词(组)替换,要注意上下句主语间的互换.例如: 3.The runner couldn't catch up with the others in the race. The runner _______ _______ the others in the race. 4.Tom borrowed a picture book from the boy just now. The boy _______ a picture book _______ Tom just now. 答案:3.fell behind 4.lent;to 三、用派生词或一词多义改写 此类题型可采用“词类转换法”,利用某些派生词或词性相异的词组来代替原句中的某些成分.此时句子结构会发生一些变化.例如: 5.The snow was heavy last night. It _______ _______ last night. 6.The foreigners have visited the Great Wall. The foreigners have been _______ _______ _______ to the Great Wall. 答案:5.snowed heavily 6.on a visit
