1．It is said that many people are worried about the year 2012，________they think the earth will be destroyed by disasters.
A．when B．where
C．as D．which
解析：考查定语从句。句意：据说很多人担心2012年，他们认为那一年地球会被灾难摧毁。关系副词when引导非限制性定语从句修饰2012，when在从句中作时间状语。
答案：A
2．I have never heard ________stories ________he told.
A．such；which B．such；as
C．such；like D．so；that
解析：考查定语从句。先行词由such修饰时，定语从句的关系代词常用as，本题中as作told的宾语。句意：我从未听过他所说的这类故事。
答案：B
