He never went out without bodyguards, whose job it was to kill anyone who displeased him.為什么不是whose job was to...,請解釋it.

熱心網友

whose job引出一個定語從句， it 作從句的形式主語， to kill....不定式短語作從句的真正的主語。用it 作形式主語， 以免頭重腳輕。 此句等于： He never went out without bodyguards,and it was their job to kill anyone who displeased him.這是個并列句。你說出的句子是個含非限制性定語從句的復合句。 當然也可以寫成你上面說的句子--- ...,whose job was to kill.... 這時to kill...不定式短語作定語從句的表語了。 三句話表達方式不同， 但意思是一樣的。 不知道你清楚了沒有？
