A developing country usually receives more public aids than ______ a developed country.
A. in B. it receives in C. does D. it does in
问题1: 答案里说 more...than 引导的比较状语从句“前后成分要对等;此处比较对象都为国家”是什么意思?前后成分对等是指than前面是句子后面也是句子,前面是名词后面也要是名词这个意思吗?
问题2: 比较对象是“国家”,那么“国家”这个词所做的成分也要一样吗?在than后面也必须做主语吗?
B选项可不可以改成 it is received in,it指代public aids?
C选项改成it is done in,it指代public aids?
A developing country usually receives more public aids than does a developed country.
比较分句采用了倒装结构,以突出比较分句的主语。如果不倒装则为
A developing country usually receives more public aids than a developed country does/receives,
主句的比较短语more public aids为比较项,其对应项在从句中作宾语必须省略。从句谓语动词receives通常用助动词替代,所以用does。需要说明的是,如果不倒装,谓语动词用does或receives都是可以的,但如果倒装,则只能是does,不能用receives。
