點睛

本句包含兩個分句。前一個分句的主干是I was eating lunch，其前的About six years ago是介詞短語作狀語，其后的when a woman and a young boy sat down at the next table為狀語從句。后一個分句的主干是I couldn't help overhearing parts。

couldn't help doing是個固定表達(dá)，意為“禁不住做某事，情不自禁地做某事”。如：

She couldn't help smiling. 她禁不住笑了起來。

overhear意為“無意中聽到，偷聽到”。如：

I happened to overhear what he said. 我碰巧聽到他說的話。
