Question

Spelling Bee is a contest _____ competitors, usually children, are asked to spell as many  words as possible.

A．which

B．where

C．what

D．when

Answer 1

B

试题分析：考查定语从句：先行词是a contest，定语从句中不缺主宾表，缺少地点状语，用关系副词where引导定语从句，句意：Spelling Bee是个参与者，通常是儿童，被要求尽可能多的拼写单词的比赛。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。
