They have helped us a lot,but we really fell sorry that we have nothing to give them in return.
What did he do in return for your kindness?
请问老师,两句例句中的in return分别是干什么成分? 而in return for后接的内容是作为目的还是定语?
They have helped us a lot,but we really fell sorry that we have nothing to give them in return. （方法状语）“以报答的方法” 回报他们。
What did he do in return for your kindness? （目的状语）“为了回报你的好意” 而做某事。
状语的名字，一般是依据某成分在句中的“语义”，而命名的。诸如：时间、地址、缘由、条件、目的、让步、比较、方法、随着等。
