Question

Can you think of some cases __________drivers obviously knew the traffic rules but did not obey them.

A．which

B．as

C．where

D．that

Answer 1

C

考查定语从句的关系词。先行词是some cases，后面从句__________drivers obviously knew the traffic rules but did not obey them缺少状语，当case，situation,position,condition等这类抽象名词作先行词，且后面定从缺少状语时，定从通常用where引导。所以选C。
