老师好!
I am very sorry for all the trouble this has caused you.
本句中this has caused you如何理解?干什么成分?
盼解惑!
理解以下两个使用方法就OK了:
be sorry for:对/因......感到抱歉。
cause you all the trouble:cause 可以跟双宾语,意为“给你带来所有这类麻烦”。cause 接双宾语的使用方法跟give, bring, offer 等相似。
因此,this has cuased you 是定语从句,修饰 all the trouble,省略了关系代词。
我举几个类似的例句:
These are all the books I have brought you.
This is all the advice she has given us.
They are grateful for all the help we have offered them.
