一道英语改错题求解
题：If people cannot afford to buy their own house,they can rent property from a private landlord,as 10% of the population does,or from their local council.
这句话中的as 10% of the population does是错误的,应该改成as do 10% of the population,请问这里为什么要用倒装使用法?

答案

首先是10% of the population 是复数而不是单数,因为 population指“人口”总称,是集合名词时,常用单数.作主语,其谓语动词可以用单数,侧重整体；也可用复数,侧重个体.这里是侧重个体的.所以用do而不用does.
其次,as可以引导倒装句用于强调,在这句话中,as do 10% of the population 是对前面rent property from a private landlord这个的修饰,强调有10%的人会这样做.
