This method saved half the labor that
will be needed
to move all the books downstairs.
选项
A、would need
B、would be needed
C、would have needed
D、would have been needed
答案
D
解析
(1)画线部分错误分析。
本题考查含蓄式虚拟语气的用法。题干中的that从句表示与过去事实相反的情形,应当选用表过去时间的虚拟语气;此外,that引导的定语从句,其先行词为labor,它在从句中作主语,根据句意,定语从句应选用被动语态。
(2)选项分析。
根据上述分析,that从句中谓语动词应当用被动语态,由此可知选项A和选项C不可选;would be needed是表示对现状的虚拟,因而选项B可排除;根据句意需要选用表示过去的虚拟形式would have been needed,因此选项D正确。
【知识拓展】语法拓展:含蓄条件句。
很多情况下,在表示假设的虚拟语气中,有时假设的条件并不以条件从句的形式表达,而是通过上下文或句中内在的逻辑关系,或用其他形式表达出来,我们称之为“含蓄条件句”。含蓄条件句主要通过名词、连接词、不定式、分词、动名词短语、介词短语及分句来暗示。常用来表示虚拟条件的介词有with,without,in,under, but for等,它们表示的虚拟条件都可以被if从句替换。
e.g.Without air, there would be no living things.(without air=if there were no air)
没有空气,便没有生物。
But that I saw it(=If I had not seen it),I could not have believed it.
要不是亲眼所见,我是不会相信的。
Seen from a high mountain(=If it were seen from a high mountain),the field in which wheat is growing would look like a great green sea.
倘若从高山上看,麦田就像一片碧绿的大海。
An honest man would not say this.(=If the man were honest,he wouldn’t say this.)
诚实的人不会说这种话。
