一個高中英語語法的問題----高手幫忙000
八、強調介詞賓語時,要用whom而不用who/that.
It was Mary with whom Jackson first came in contack.
這個句子我看不懂,請高手寫出原句.

解答：

原句爲Jackson first came in contact with Mary.本題對Mary進行強調,
也可以將介詞with後置,It was Mary whom/that Jackson first came in contack with.這時,用whom或that都是正確的.
但當with 前置時,只能是It was Mary with whom Jackson first came in contack.沒有.with that.的用法.
