Question

—When is he willing to lend somebody some money?

—Only when    hard enough.

A.to press B.pressing C.pressed D.presses

Answer

C

【解析】

考查状语从句的省略。句意：——他什么时候愿意借钱给别人？——只有当压力足够大的时候。回答为when引导的状语从句省略句，原句应为He is willing to lend his friends some money when he is pressed hard enough，主语he和动词press是被动关系，所以此处用了被动语态，主句和从句主语一致，且从句谓语动词是be动词，所以从句中的主语和be动词可省略，留下过去分词pressed。故选C项。
