九、比拟构造比拟构造中要留意两点:1、倒装性;2、对称性
例1:Western Nebraska generally receives less 却没有从句主语。正确答案〔B〕看似没有从句引导词,事实上是省略了引导词that,应选〔B〕。that they can capture, that引导定语从句在句子中做capture的宾语。
例2:A majority of people in the United States can get all the calcium their bodies----from the food they eat. (A) require (B) requires (C) requiring (D)to require 分析:此题明显缺从句谓语动词,故首先解除〔C〕和〔D〕。〔B〕为第三人称单数形式,与主语bodies相冲突,故也可解除,因此选择A。 their bodies require from the food they eat是定语从句修饰calcium, 省略了that; 事实上they eat也是定语从句省略了that修饰the food“介词+名词”在定语从句中做表语时,关系代词和be动词可以同时省略,剩下的形容词短语做名词的后置定语。例3:To produce one pound of honey , a colony of A bees must fly a distance equals to twice around B C D the world. 分析:句子中事实上是省略了that is, a distance that is equal to, 因此equals to 应当改为equal to
例4: A neutron star forms when a star much more massive A B C than the Sun dies and exploded. D 分析:句中省略了which is, a star which is much more
