The goals_____he had fought all his life no longer seemed important to him.after which, for which, with which, at which这个题是选for which没错吧， 把FOR提前是定语从句中常常看见的，但为什么提前它的语法意义，能给个解释吗？先谢谢各位了

在定语从句中，如果引导词在从句中作宾语且动词是及物的，直接用引导词就可以了，但如果动词是不及物的，引导词又作宾语的话，就要加个相应的介词在引导词前，具体加什么介词，关键取决于与动词的固定搭配。您说的就是这种情况，fight作“奋斗”讲时，常与for搭配，作“战斗”讲时，常与against搭配。fight for the goals是所奋斗的目标，翻译成：他为之奋斗一生的那些目标看来对他一点也不重要了。又如：The man to whom my father is talking to is our headmaster.(talk to) That is the wallet for which we have been looking.(look for)
