accustomed这个单词怎样用啊?
这几个句子:
1:I have accustomed myself to working long hours.
2:I am accustomed to waking up earlier in the morning.
3:The child was accustomed to have her way.
4:to be accustomed to work hard.

1和2是常用的用法,to是介词,后面跟名词或动名词.而根据牛津高级词典,accustom还有主动的意思,表示:
To habituate,familiarize (a person or thing to (in,into,for,with obs.) something,or to do something).
因此3和4是这个用法下的被动形式,表示(在外部影响下)形成了习惯
