Question

Those successful deaf dancers think that danc--ing is an activity ________ sight matters more than hearing.

1. A.
   when
2. B.
   whose
3. C.
   which
4. D.
   where

Answer 1

D
句意：那些成功的聋哑舞蹈家认为舞蹈是一件视力比听力更重要的事情。依题意所填之空应为定语从句的关系词。四个选项中A、D两项为关系副词。B、C两项为关系代词。依据语法规则关系代词在定语从句中只能作主语或宾语，而题干中定语从句主、宾均已出现。因此可排除B、C，又因A．when在从句中只能作时间状语，而D．where才可作状语表范围或空间概念。where=in this activity。故选D。
