问题 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 本题考查虚拟语气的用法。will be needed应该采用虚拟，因为和已发生的saved这一现实相矛盾。saved是过去式．因此will be needed改成表过去时问的虚拟语气，即采用would have done的形式，而又因为主语是labor，故用被动语态，所以would have been needed符合要求。
