B．to which

C．which

D．that

答案

B

解析

试题分析：句意：当你写作文的时候，这些是你必须重视的词汇。这里是定语从句，先行词是words，attach… to把……附加于；which在这里做介词to的宾语，判断用哪个介词可以根据先行词或在定语从句中的谓语动词连用的介词，故选B.
点评：本题难度适中。定语从句是英语语法中非常重要的内容，在阅读和理解过程中起着极其重要的作用。定语从句的考查关键在于定语从句的成分分析，需要考生有分析理解复杂的句子结构的能力。这里考生容易误选A。
即学即练：It was two decades ago ______  I was in my teens______ the Chinese government decided to reform the social economic system.
A. when; when    B. that; which     C. when; that    D. before; that
解析：C。考查定语从句和强调句的混用。when引导时间状语从句，强调句型It was ...that对when引导的从句进行强调，故选C。
