问题 选择题

Stephen Hawking believes that the earth is unlikely to be the only planet _______ life has developed gradually.

A.that

B.where

C.which

D.whose

答案

答案:B

题目分析:考查定语从句:先行词是the only planet,定语从句缺少地点状语,用where引导定语从句,句意:Stephen Hawking认为地球不可能是生命逐渐发展的唯一星球。选B.

点评:定语从句的考查主要就是考查关系词的辨析,关系代词that, which, whose, whom, as, who在句中做主语,宾语,表语或者定语;where, why, when在句中做状语。要分析句子成分,看缺少什么成分,就选用相应的关系词。
