问题补充：

He was watching a failmthe scene reminded him ofhe had experienced in France.

A. that, what

B. when, what

C. whose, that

D. while, which

答案：

A. that, what

(答案→)B. when, what

C. whose, that

D. while, which

解析：第一空考查句型： be doing …when,正在做某事，正在那时，第二空考查名词性从句，从句中he had experienced后缺少宾语，所以用what,故选B。
