The man will do everything he can ------ a camera for his wi

The man will do everything he can （A.to get） a camera for his wife.
这男人会尽他的一切所能来给妻子买部照相机.
这一空的动词跟前面的can无关,不能用原形.
he can实际上是个定语从句,修饰everything.去掉后意思也还是通顺的.
The man will do everything （A.to get） a camera for his wife.
不定式to do在句中是作目的状语,说明他做一切是为了什么.
