选择题
He said it was this classroom _______ he found his lost watch and _____ he would take good care of it from then on.
A．where; /
B．when; what
C．that; what
D．where; that
答案
答案：D
题目分析：考查定语从句及宾语从句。第一空考查定语从句，先行词为classroom，在从句中作地点状语，故用关系副词where引导。第二空考查宾语从句，宾语从句中and之后的that不可以省略。句意：他说，就是在这个教室他发现丢失的手表并从那时起保管好它。故D正确。
