“be used to doing”是英语中常用的短语,核心含义是“习惯于做某事”,强调对某种行为或状态的适应。以下是具体解析:
表示主语(通常是人)对某件事(动作或状态)已经“习惯、适应”,不觉得陌生或困难。
结构中的“to”是介词,而非不定式符号,因此后面必须接动名词(doing)或名词/代词。
“be”动词会根据主语的人称、时态(现在/过去/将来)调整:
现在时:I am used to... / You are used to... / He/She is used to...
过去时:I was used to... / They were used to...
将来时:I will be used to... / Will you be used to...?
否定:在“be”动词后加“not”,如:I am not used to staying up late.(我不习惯熬夜。)
疑问:将“be”动词提前,如:Are you used to the cold weather here?(你习惯这里的冷天气吗?)
需注意与另外两个形似短语的区别,避免误用:
短语 | 含义 | 结构特点 | 例子 |
---|---|---|---|
be used to doing | 习惯于做某事 | to是介词,接doing/sth. | She is used to drinking coffee.(她习惯喝咖啡。) |
used to do | 过去常常做某事(现在不做) | to是不定式,接动词原形 | He used to smoke a lot.(他过去常抽烟。) |
be used to do | 被用来做某事(被动语态) | to是不定式,接动词原形 | Knives are used to cut things.(刀被用来切东西。) |
动名词:After moving to London, I got used to driving on the left.(搬到伦敦后,我习惯了靠左开车。)
名词:She is used to the busy life in the city now.(她现在习惯了城市的忙碌生活。)
过去时:I wasn't used to eating spicy food when I first went to Sichuan.(刚去四川时,我不习惯吃辣。)
将来时:Will you be used to working from home?(你会习惯居家办公吗?)
“be used to doing”的关键是“适应/习惯”,核心是“to”作为介词,后接动名词或名词。记住与另外两个短语的区别,就能准确使用啦!
