A. That; why

B. What; when

C. What; where

D. That; how

答案：

A. That; why

(答案→)B. What; when

C. What; where

D. That; how

解析：B句意：当你不喜欢一件事情时，你应该做的是改变它。不要抱怨。“you are supposed to do”为主语从句，该从句缺少宾语，表示“事物”且语境中并无选择含义，故用what引导；“you don like a thing”为时间状语从句，作are supposed to do的状语，说明其时间，故用when引导。因为主语从句“What you are supposed to do”中含实义动词do，故is后的表语需为省去不定式符号的不定式，故change作表语。
