She was very upset at what to him was just a throwaway remark.
请老师剖析和翻译这个句子, 谢谢!
She was very upset at what to him was just a throwaway remark.
剖析：句中的 what 就是所谓的缩合连接代词或融合连接代词，在此等于 the thing that / which，其中 what to him was just a throwaway remark 为宾语从句，用作介词 at 的宾语。在宾语从句 what to him was just a throwaway remark 中，what 是主语，to him 是状语（表对象，意思是“在他看来”“对他来讲”），was 是系动词，a throwaway remark 是表语。
翻译：她对于他随口说说的事感到非常不开心。
类例：What to some people are matters of principle, to others seem merely straining at a gnat. 有的人觉得是带有原则性的问题，在另一些人看来只不过小题大作。
