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

我很羞愧曾经对他祸过。

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

布莱克上尉很惬意地打了呵欠，驱走了最后一丝睡意，祸地笑了起来。

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

"他的能获,他却祸。"

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

他看我挣扎的样子，嘴角闪过一丝祸的笑容。

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

他现在可以对我们祸,但是要不了多久他就会转喜为忧。
