use to do和use doing 和use for doing sth有什么区别以及中文解释

亲,想问的是不是 used to do 和 be used doing 和be used for doing这几个词组呢?
1.used to do 翻译为“过去常常做某事”,
例如:I used to play ball.过去我常常踢球.
2.be used to doing 翻译为“习惯于做某事”,
例如:I am used to playing ball after dinner.我习惯于晚饭后踢球.
3.be used to do = be used for doing 翻译为“被用来做某事” ,
例如:The computer is used to work.= The computer is used for working.
