这句话要有语境才能给你一个比较合理的答复。如果是对方询问身体健康情况,最好是说:“I am quite well. Thank you."
如果是日常会话,常见的说法是:”I am fine. Thanks"
I am quite good these days /I am ok these days /I am fine these days /Everything goes well these days /Everything is ok these days /Nothing goes wrong these days /Everything is perfect these days .
I'm fine,thanks
I'm fine,thank you.
