i can't stopped 这是错的
可以用
i couldn't stopped 或者 i can't stop
不能现在时和过去式混用
语法是 i can't stop to do sth 我不能停下去做某事
或者 i can't stop doing sth 我不能停止做某事
Excuse me, I can't stop to talk. I'm rushing for a train.
对不起,我不能停下来谈谈了。我去赶火车。
I miss you, so I can't stop blinking to prevent my tears from flowing.
我想你了,于是我不停的眨眼,因为我不想让泪水流出来。
