be used to表示“习惯”,意思是作为某个活动,状态或情况的“一般经常性行为”。通常是指一段时间来一直做某件事情。它和always或经常搭配使用,例如:I'm used to getting up early in the morning(我习惯于清晨起床)。
used to 和be used to相反,表示“过去经常”,意思是过去经常做某件事,但现在不再那么做了。因此, used to 后面的动词通常是过去式(不管任何时态都是过去式),例如:I used to speak English fluently(我以前会流利地说英语)。
总而言之,be used to表示现在经常性做某事,而used to表示过去经常性做某事,但现在不做了。
