病好了 的英文怎么说?

[1] be over it
  be over a disease[2] get over it
  get over a disease[3] overcome

我病好了 = I'm over it now.

over 後面也可以加病的名稱，如:

I'm over the flu.

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.
