词典解答
上面的试题与英语的实际用法背离得太远了,因而可能对学生和教师产生负面影响。关于定语从句中关系代词 who 和 whom 的用法,英美英语语法学家早就有了明确的说法。例如,PEG(第四版,p.82)说:
“动词的宾语: whom 或 who 或 that
宾语的形式是 whom,但是它太正式。在英语口语中我们通常使用 who 或 that:
The man who I saw ...
The girls who he employs ...
The man who/whom I spoke to ...”
CGEL(§6.35)也有明确的论述：
“当关系代词是宾语时,可以看到以下几种形式:
This is a person you should know. "
who/whom
