7.There was something wrong with the network,or the e-mail_______ earlier.( )A. | could have been sent | B. | might be sent | ||
C. | need have been sent | D. | must be sent |
分析 网络出了问题,否则这封电子邮件早就发出去了.
解答 答案是A.本题考查的是含蓄的虚拟条件句.英语中表示条件时常常没有连词if,而是用otherwise、or、but、but for等形式表达条件,这种类型的虚拟语气被称之为含蓄的虚拟条件.本题中or表示"否则",相当于一个虚拟条件句.这里要表达的意思是"如果网络不出问题的话",由句中的was判断这是一个与过去事实相反的虚拟;与过去事实相反的虚拟条件句中往往用过去完成时,而主句中则用"would/should/could/might+have done",由此判断答案是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.
