The woman (who, whom) we thought to be her turned out to be her sister.
答案选whom
可wh-不管在主句和从句中都是做主语,为什么选择whom宾格呢? 不定式后补语是her不是wh-吧?
谢谢您。
There’s the man (that) / (who) we met in the pub last night.
那就是我们昨晚在酒吧里碰见的那个人。
在正式文体里,更常用 whom。
She married a man whom she met at a conference.
她嫁给了她在会议上遇见的一个男人。
(以上摘自《牛津英语用法指南》第四版626节)
所以,在下面的句子中,选择who 或者whom 或者省略,都是正确的:
The woman (who, whom) we thought to be her turned out to be her sister.
(who或者whom 是thought 的宾语)
