题目内容
15.-This plane have taken off half an hour ago.-I'm terribly sorry,madam.( )
A. | must | B. | could | C. | should | D. | would |
分析 -飞机半个小时前就应该起飞的.
-非常抱歉,女士.
解答 答案:C
句意表达的是与事实相反的假设,should have done本该做而没有做的事;must一定,表示推测,could能够,should应该,would将会;从答语的道歉中可以知道,飞机没有起飞,本来应该在半个小时前起飞的.故选C.
点评 虚拟语气是表示与事实相反的假设,构成方式有:对现在或将来,条件句中用一般过去时态,主语用情态动词加动词原形;对过去,条件句中用过去完成时态,主语用情态动词加完成时态.学习时,要牢记构成方式.
