He didn't speak to me today, either in response to my vacant expression or because he was still angry about our squabble yesterday.

他今天没有跟我说话，也没有对我空白的表情作出任何反应，也许他还在为我们昨天的口角生着闷气。

He was simply in disbelief. Usually very agreeable, he now quit speaking altogether and no amount of words could penetrate the vacant expression he wore on his face.

他就是不能相信父亲去世这一事实。通常，他是一个令人愉快的人，现在却一言不发，无论说多少话都不能透过他木然的脸部表情了解他的心事。

As it is difficult to do two things at the same time, the marquis answered Mathilde with a vacant expression as though he were reciting a lesson.

由于很难同时做两件事，侯爵一脸茫然地回答玛蒂尔德，就像在背课文一样。

An hour later Dad was no longer grinning. Tyler had not repeated his wish to go to college, but he had not promised to stay, either. He was just sitting there, behind that vacant expression, riding it out.

一个小时后，爸爸不再咧嘴笑了。泰勒没有再提他上大学的愿望，但也没答应留下来。他只是出神地坐在那里，安然承受。

I don't know what Shawn saw on my face—whether it was shock, anger or a vacant expression. Whatever it was, he was delighted by it. He'd found a vulnerability, a tender spot. It was too late to feign indifference.

我不知道肖恩在我的脸上看到了什么——是震惊、愤怒还是茫然的表情。不管是什么，他都为此感到高兴。他终于发现了一个弱点，一个痛处。再假装漠不关心已经太迟了。
