【题目】 Only when we realize how serious the environment is damaged, _______is usually ignored, ______ try our best to fight against it.

A, it; can we B. what; can we

C. which; we can D. which; can we

【答案】D

【解析】

试题分析:考查定语从句及倒装句。本题_______is usually ignored是非限制性定语从句,这个非限制性定语从句修饰前面的句子:how serious the environment is damaged。非限制性定语从句修饰整个句子用which引导。Only when we realize how serious the environment is damaged ______ try our best to fight against it.第二空考查倒装句。当only修饰状语(副词、介词短语)或状语从句时,主句部分用部分倒装。因此此处用部分倒装。句意:我们通常忽视环境被严重破坏这一事实。只有当我们意识到环境被破坏得多么严重,我们才能尽我们的能力去与破坏环境的行为作斗争。故D正确。
