Question

______ you are supposed to do ______ you don't like a thing is ______ it. Don't complain.

A．That; what; change	B．When; that; to change
C．What; when; change	D．What; that; changing

Answer 1

C

試題分析：句意：當你不喜歡一個東西的是時候，你應該做的是改變它。不要抱怨。第一空填what連接主語從句，在主語從句中what做賓語，第二空填when，引導時間狀語從句，第三空是省略to的不定式做表語，因為前面主句有do。所以選C。
