“I might shoot through.”就是“我可能先走了”

在澳大利亚口语里，“I might shoot through.”通常表示“我可能先走了”或“我得赶快离开”，不是“射穿”。shoot through 比 leave 更随意，也更强调迅速；有时还暗示为避开某事而走。

A: Are you staying for another coffee?
B: No, I might shoot through. I’ve got an early start.

朋友聚会或熟悉同事之间这样说很自然。正式会议或需交代去向时，用“I’ll need to leave at three.”更清楚，免得显得突然溜走。
