accustom(ed)
1.accustom用于主动语态和被动语态都可以。例如：
- I have accustomed myself to it.
- Necessity has accustomed me to it.
- I am accustomed to it.
- I have got accustomed to it.
但用在被动语态的多。注意各句里都用to。
2.accustomed 后面接不定式也有。例如：I am accustomed to do hard work. 接to和动名词也很普通，跟接不定式意思相同。例如：I am accustomed to doing hard work. 大概说简单的行为多用to和动名词，说复杂些的行为多用不定式。例如：
- I am accustomed to riding.
- I am accustomed to ride for an hour every morning.
- I am accustomed to speaking English.
- I am accustomed to speak English in public.
