1.You _________ the book to show me because I have just bought one from the bookstore.( )A. | needn't have brought | B. | can't have brought | ||
C. | shouldn't have brought | D. | wouldn't have brought |
分析 你本不必带这本书给我看,因为我刚刚从书店买了一本.
解答 答案是A.
本题考"查情态动词+have done"的结构.needn't have done是虚拟语气,表示"本不必做而实际上却做了";"can't have done表示推测"不可能已经…"; shouldn't have done是虚拟语气,表示"本不应做但事实上做了";wouldn't have done是虚拟语气,表示"本不会做但事实上做了";根据题意,我已经买了一本,所以你"本不必带来";由此判断答案选择A.
点评 在掌握虚拟语气的规则的基础上,判断题干属于什么类型的虚拟,然后根据语境,选用恰当的动词形式表达虚拟.
