《世纪金榜高中全程学习方略》北师大版英语选修6 Unit17

It was Guo Meimei ______ the Red Cross should thank for her “contributions” to the construction of the organization.

A. who     B. whom     C. which     D. that

    书后给的答案是D, 解释为本句为强调句，被强调部分是 “Guo Meimei”,在句子中作宾语，故不能用who，所以用that。但是笔者认为此种说法是错误的，“that”虽然正确，但是“whom”也是正确的，甚至 “who”在非正式的情况下也是可以的。

     例如：在《实用英语语法》书中，张道真认为在强调宾语或介词宾语时，若是人，关系代词用whom，间或用that。强调主语时，若为人，可用who（间或用that）引导后面部分。

    It was your sister whom Nancy saw in Tokyo last week.（强调宾语）

    It was Jim in whom she still had her faith.

    It was Peter with whom I first came in contact.
