题型:不详难度:来源:
They received demands that the work ________ at once.
A.must be doneB.would be doneC.had been doneD.be done

答案
D
解析

试题分析:考察虚拟语气。名词demand后面的同位语从句中要使用虚拟语气,使用should+动词原形;should可以省略。句意:他们收到这个命令,这份工作要立刻被做。故D正确。
点评:英语中有4——四个表示“要求”的词,require, ask ,tell, demand;3——三个表示“建议”的词,suggest, recommend, advice;2——两个表示“命令”的词,order, command ; 1——一个表示“坚持”的词,insist。他们后面接 should+动词原形 的虚拟语气。Should可以省略。这些动词转换的名词后面的从句也要使用虚拟语气。
