“雪上加霜”，意思是在雪上还加上了一层霜（literally snow plus frost），常用来比喻接连遭受灾难（one disaster after another），损害愈加严重。与英文习语“add insult to injury”意思相近，表示“ to make a bad situation worse”。

例句：

今天早上我的车差点没发动起来，雪上加霜的是开到车道上车胎也漏气了。

My car barely started this morning, and to add insult to injury, I got a flat tire in the driveway.

俱乐部不仅拒绝了他，还公布了一份被拒绝的申请者名单，真是雪上加霜。

Not only did the club refuse him, but it published a list of the rejected applicants-that's adding insult to injury.
