2、for的用法
（1）do sth for sb,为某人做某事，He's waiting for the bus. I do this for you.
（2）do sth for sth,为了某事而做某事，表目的，He went home for his book. She works hard for success.
英语不用for doing sth来表示目的，如He went there to visit her uncle. Wrong: He went there for visiting her uncle. 除非该动词ing已名词化，如He went there for swimming.
（3）表用途，The knife is ended for cutting things.
（4）表原因，Thank you for coming to see me. He can't speak for laughing.
for doing 不能表示目的
