_______she looked up,the strange man had disappered.which is wrong?
A.at the time B.when C.at the time when D.the moment

连接词when引导状从,在这里意思表述等同于the moment/the time/the minute等,后者其实后面省略了that,that后跟定语从句“she looked up”.C中when she looked up为定从,修饰前面的the time,为便于分析句子成分可省略不看.即At the time,the…… 其中At the time作状语成分
