But selfishly, I'm more fascinated by Michelle Obama and what she might be able to do, not just for this country, but for me as an African-American woman. (09.12 Passage 1)
分析主干:I'm fascinated (by...)
1.by 有两个宾语,它们用and 并列。by 的第二个宾语是what 引导的从句,主干部分用了do (what) for 结构。两个表示对象的for 介词短语又由not... but 结构并列,“不只是能够为这个国家做些什么,而且是要为我做些什么”。
