Question

American women usually consider their best friend as someone ________ they can talk frequently.

A．who	B．whom
C．about which	D．with whom

Answer 1

D

试题分析：句意：美国的妇女们常常将她们最好的朋友视为那种能够经常交谈的人。本题中存在定语从句，talk with sb 与某人交谈，with 提到定语从句的句首，后接whom 作为宾语，定语从句中缺少宾语，故选D.
点评：定语从句掌握好三个问题一是先行词，二是连接词，三是成分问题，定语从句的关系词判断是看从句中缺不缺成分，应将先行词带到从句中，如果句意语法符合即缺成分，那么定语从句用关系代词来引导，反之则用关系副词来引导定语从句。
