题目内容

8．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

分析研究人员正在进行冬眠实验，并可以使用化学物质使活细胞进入类似冬眠的状态，在这种状态下，他们就不会衰老．

解答答案：C
分析句意可知，本句是定语从句；由于先行词 state"状态"属于抽象的地点名词，并且该从句中缺少状语；故用关系副词where；A．for which 通常表示原因或目的，表示原因时，可以用关系副词why替换；B．D关系代词that只能在定语从句中作主语或宾语；故选C

点评本题考查了关系副词where的用法：即在定语从句中，当先行词为抽象性的地点名词（如：point，case，activity，position，state等）时，应使用关系副词where；判断先行词为抽象性的地点名词的依据是：1．当定语从句中有主语和宾语，缺少状语时；2．先行词为既不表示原因也不表示时间的名词时．
