be used to do的意思是被用来做某事;be used to doing的意思是习惯于做某事.
used to表示过去常常做某事.
例句:I used to play football after school.过去我常常在放学后踢球.
be used to do的意思是被用来做某事;be used to doing的意思是习惯于做某事.
be used to 被用来做
used to + do："过去常常"表示过去习惯性的动作或状态,但如今已不存在.
Mother used not to be so forgetful.
Scarf used to take a walk.(过去常常散步)
be used to + doing：对……已感到习惯,或"习惯于",to是介词,后需加名词或动名词.
He is used to a vegetarian diet.
Scarf is used to taking a walk.(现在习惯于散步)
use doing 没有这个用法
虽然你的原问中有错误,但这个问题的确是学生们常常碰到,并且是个考试的热门考点,问得很好.
used to do曾经/过去常常做某事,如：
He used to live in the country.他曾经住在农村.
be used doing习惯于做某事,这里的to 是介词,后面不跟动词原形,跟ing形式,如：
He is used to living in the country now.他现在习惯了住在农村.
be used to do被用于,如：
This knife can be used to cut things.这把刀能够被用于切东西.
