"敷衍"用英语可以翻译为 "to go through the motions" 或者 "to half-heartedly do something". 这个词的来源可能源自中文语言，它指的是在做某事时表面上装作在努力，实际上并没有真正专注或尽心。

例句：

He just went through the motions during the presentation, not really engaging with the audience. 他在演讲中只是敷衍了事，没有真正与听众互动。

She half-heartedly did the assignment, not putting in any real effort. 她在做作业时只是敷衍了事，没有真正付出努力。
