我已经习惯了I am used to it为什么不是I’m used to do it

我已经习惯了I am used to it为什么不是I’m used to do it I am used to it为什么解释为我习惯了?be used to 不是被用于的意思吗? i'm used to it为什么要加am I'm used to it. I am used to it now I am used to travelling by air.I am_______to it. i am used to.. i am used to... Finally I also used to it 最后我也习惯了.是这样翻译的么 有语法错误么. I am not used to it,always endured not to be good I only to I am used to lonely 英语翻译I am used to loving you是不是 翻译为 爱你是一种习惯?I am used to love
