It was on my way to school this morning I picked up this wallet.

A. where

B. that

C. when

D. how

答案：

A. where

(答案→)B. that

C. when

D. how

解析：考查强调句型。强调句型基本结构：It is/was被强调成分that/who其它成分；强调句型最大的特点是把it is/was…that/who…去掉，句子仍然成立。本题强调的是on my way to school this morning.句意：就是在我上学的路上，我捡到了这个钱包。故B正确。
