the amount of money they are able to earn cannot be justified by the amount of work they do

问题描述:

the amount of money they are able to earn cannot be justified by the amount of work they do
the amount of money 是句子的什么成分?为什么放主语之前?

是主语,
they are able to earn 这个才是定语,修饰the amount of money
他们能够赚到的钱的数量取决于他们的工作量the amount of money 做定语从句的宾语吗?对的,还原回去就是 they are able to earn the amount of money ,所以充当宾语没错to earn 是目的状语吗?
