be use for doing sth

【used to do sth】和【be used to do sth】 ①used to do 过去常常（表示现在不再） eg: I used to swim in the lake near my village when I was young. ②be used to do 被用于。。。=④be used for sth./doing sth. eg: Wood can be used to make paper. ③be used to doing习惯于做某事 eg: My grandpa is used to going for a walk after dinner. ③和①②很容易区别，而②可以认为和be used for doing sth意思一样。 【be used to do 和be uesd for sth /doing sth.都可以表示“被用来……（表目的）”区别如上， 动词的形式不同。 e.g. The knife is used to cut apples. =The knife is used for cutting apples. 】 Originally posted by ashao at 2010-02-09 2250: be used to do貌似这个易和be used to doing sth——过去常常做某事or习惯于——混淆，呵呵

第一个用于做某事 第二个过去常常做某事 第三个习惯做某事

常常干，
