________ you are supposed to do ________ you don"t like a thing is change it. Don"t complain.

A．That; why	B．What; when
C．What; where	D．That; how

答案

B

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"t 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。
