我感冒好了 = I got over the cold. = My cold is gone. = I'm over the cold. = I'm over my cold. = I got over my cold. = I've recovered from the cold. = I've recovered from my cold.
以上是以普遍程度排序,最普遍的為優先,the cold 比 my cold 常用。
I overcame the cold = 我戰勝了感冒,表示我的感冒好了,此說法較不普遍,但美國人聽的懂。
如果感冒一直沒好,可以用 linger 這個字,例如:
If your cold lingers, you may have something more serious.
