1. 【2012北京市西城区第一学期期末】The Great Wall is the place ____ almost all tourists would like to visit when they come to Beijing．
A．why B．which C．when D．where
【答案】B
【解析】考查定语从句，先行词place 在从句中作谓语动词visit的宾语，所以要用关系代词which。如果不注意分析句子的结构，就会受思维定势的干扰而误选D。
2. 【2012上海青浦高三期终调研】 Researchers are now conducting hibernation experiments and can use chemicals to put living cells into sleep-like state ______ they don’t age.
A. for which B. that C. where D. which
【答案】C
【解析】考查定语从句的关系词。先行词state在这里表示状态，属于抽象的地点，语境为：在这种状态下，这些细胞不会衰老，所以用where相当于in which。
