【题目】– Where did you find the wallet I lost yesterday?
-- It was on the playground ______ we played basketball.
A. that B. where C. which D. when
在线课程【答案】B
【解析】
试题分析：句意：——你昨天在哪里找到我丢失的钱包的？——在我打篮球的操场上（发现的）。这一道题很有可能会选择A，误以为是强调句，其实，这句话是个省略句，后面省略掉了that I found the wallet.这题考察的还是定语从句，先行词为playground作地点状语。故选B。
