老师好!A of B 这种结构中,A的单复数是否需要根据B发生变化?如:The proportion of aging populatiom in X and Y is very high. 这里想表达x和y两个国家的老龄化人口都很高。还是要用The proportions of aging populatiom in X and Y are
very high.谢谢老师!
The principal decisions to be made by auto insurance buyers are what coverage to buy, what amounts of insurance to buy, and what agent and company to buy from.
请问这个句子中的what的用法是什么?
as per sth(following sth that has been decided)中的as应该是介词吧。还有as per usual,这里的as词性。The work was carried out as per instruction.It also require grain purchasers to conduct quality checks as per national rules.
