幸灾乐祸

I felt shame that I had ever joyed in his discomfiture or pain.

我很羞愧曾经灾乐祸过。

Captain Black yawned deliciously, rubbed the last lethargy from his eyes and laughed gloatingly.

布莱克上尉很惬意地打呵欠，驱走最后一丝睡意，灾乐祸地笑起来。

He gloated over his fellow student's failure to win the prize.

"的同学未能获,却灾乐祸。"

A smirk flickered at the corner of his mouth as he watched my struggle.

看我挣扎的样子，嘴角闪过一丝灾乐祸的笑容。

He may laugh at our discomfiture now,but before long he’ll be laughing on the other side of his face.

现在可以我们灾乐祸,但是要久就会转喜为忧。
