题目内容

They demanded that the books ________to the school library at once．

[　　]

A．return

B．should return

C．was returned

D．be returned

答案：D
解析：

受主从句时态一致性的影响，本题易误选C项。Demand与request，require的意思相同，接宾语从名作它们的宾语时，从句中都就用虚拟语气谓语动词形式。

提示：

demand 后接宾语从名时，从名中的谓语动词应用 should ＋动词原形或直接用动词原形。又因句中return与the book之间在逻辑上含有被动关系，因此return要用被动式。
