Question

One million people of the city, ______ thought little of the event, were asleep as usual that night.

A．where

B．which

C．who

D．that

Answer 1

C

试题分析：考查定语从句。短定语从句who thought little of the event修饰One million people在句中做主语。B不能在句中做主语。B不能指人。That不能引导非限制性定语从句。故C正确。
点评：对于定语从句的考查要注意分析句子结构，看定语从句中缺什么样的成分，如果缺主语，宾语，表语，定语要使用关系代词，如果缺少状语，则要使用关系副词。同时注意只用that和只用who的一些特殊用法。
