be used to doing和used to do的用法

be used to doing和used to do两个短语看起来很像，但在用法上有所区别，本次我们就来介绍两种用法的区别。

used to do 表示过去常常做某件事，be used to doing 表示习惯于做某事。

be used to与accustomed to在结构上相同，都表示”习惯于“，used是形容词，to是介词，只能接跟名词、代词或动名词，通常采用"ing"形式。例：He was used to the cold weather after he lived there for two years．

1）They got used to living in the countryside．他们已习惯于住在农村。

used to do中to跟动词原形，不需变换形态。例：We used to go there every year.
