The teacher made a request that all the homework ________ before class.
A. should hand in
B. must be handed in
C. be handed in
D. were handed in
题目解答
答案
C. be handed in
解析
本题考查虚拟语气的用法，核心在于掌握request后的从句结构。当主句动词为make a request时，其后的that从句需使用虚拟语气，即动词原形（通常省略should）。此外，还需注意被动语态的正确形式。
-
确定虚拟语气结构
主句动词为made a request，其后的that从句需用虚拟语气，形式为（should）+动词原形。由于主句为过去式，从句中的should可省略。 -
判断被动语态
homework是动作的承受者，需用被动语态，即be handed in（hand in的被动形式）。 -
排除干扰项
- A. should hand in：主动语态错误。
- B. must be handed in：must不符合虚拟语气要求。
- D. were handed in：过去完成时与语境不符。
- C. be handed in：符合虚拟语气（省略should）和被动语态的要求。
