40. It has come to be realized _____particular matters in the air expose us to life's real danger a.what b. which c. when d. that

解题思路：见下
解题过程：
选B。which在这里是作定语修饰particular matters，是“哪些”的意思。整句话是it做形式主语，然后which引导的从句做真正主语，称作真正主语从句。expose sb/sth/yourself to sth是短语搭配，意思是;使面临，使遭受（危险或不快）。句意：人们逐渐意识到空气中哪些特别的物质使我们遭受危险。
而what是“什么”或“...的（事/话/东西等）的意思。所以根据句意说明大家已经知道哪些物质对人们有危险了，所以不能用what。when往往在从句中做时间状语； that引导名词性从句不做成分，也没有汉语意思，所以这些答案都不对，最佳答案选B。
