Question

Last week, only two people came to look at the house, ____ wanted to buy it.

A．none of them	B．neither of whom
C．none of whom	D．both of them

Answer 1

B

试题分析：考查定语从句。本定语从句的先行词是two people, whom指代先行词在句中作为of的宾语，因为是两者之间，排除AC，none指三者或三者以上。D项不是定语从句。故B正确。
点评：关系代词在句中作主语，宾语，表语或者定语；关系副词在句中做状语。所以要分析句子中缺什么成分来确定使用何种关系词。
