Question

---Where did you come across our Chinese teacher ?
--- It was in the supermarket ______I purchased mooncakes．

A．that

B．which

C．where

D．when

Answer 1

C

试题分析：考查定语从句：句意：--你是在哪儿遇到我们的语文老师的？--是在我买月饼的超市。说明是定语从句，先行词是the supermarket，定语从句缺少的是地点状语，用where引导定语从句。选C。
点评：这是一个易错题：考生容易当成是强调句。实际上这是省略的强调句：完整句子是：It was in the supermarket that I purchased mooncakes that I came across our chemistry teacher. 要填的词是强调部分所带定语从句的引导词。
