Question

 Those successful deaf dancers think that dancing is an activity_____sight matters more than hearing.

A.when              B.whose             C.which             D.where

Answer

 D

解析:where引导定语从句,作activity的定语,表示“视力比听力更重要”。where引导定语从句时,在从句中作状语,因为sight matters more than bearing是一个完整的句子,所以要用where引导。when引导定语从句时,意为“在……的时候”,其先行词常常是表示时间的名词。whose引导定语从句时,在从句中作定语,表示先行词与whose所修饰的名词之间是所属关系。which引导定语从句时,在从句中作主语、宾语或表语。
