376. The boy's foolish question irritated his mother who was busy with housework and had no interest in talking.

译文　小男孩愚蠢的问题让他妈妈很生气，因为她当时正在忙着做家务，没兴致聊天。

点睛　短语be busy with意为“忙于”，相当于be engaged in。have no interest in doing sth.意为“没兴趣做某事”。irritate sb.是“激怒某人，惹恼某人”的意思。

考点归纳　interest一词可以作动词，表示“对……感兴趣”；也可以作名词，表示“兴趣”。如：

1) She no longer takes any interest in that book. 她对那本书不再感兴趣了。

2) What interested her most was the longitude line. 她最感兴趣的是那条经线。
