for與to的區(qū)別:
In English, prepositions are used to indicate the relations between the predicate and its arguments. For, when used for this purpose, indicates the benefactive relation, i.e. some one who benefits from the event specified by the predicate.But TO is used to indicate the dative relation, i.e.the goal to which the action is directed. Compare the following two sentences:
(a) John gave a gift to his girlfriend.
(b) John gave his life for his country.
簡(jiǎn)單來說就是,for更注重目的,表示有一方受益,to更注重指向
