這個(gè)句子用了虛擬語氣--加入沒有你的及時(shí)幫助,我們就不能按時(shí)完成那份工作了.
虛擬語氣是由should could might were was 等構(gòu)成,不可以用can shall 等原型形式的.
你也說了是對(duì)過去的否定判斷,不錯(cuò),所以應(yīng)該選D.
We__the work on time without your timely help.( )
We__the work on time without your timely help.( )
A.had't had finished B.didn't have finished
C.can't have finished D.couldn't have finished
C,D同樣是對(duì)過去的否定判斷,句子中沒有時(shí)態(tài)應(yīng)該選C,為什么答案是D?請(qǐng)說明一下原因,
A.had't had finished B.didn't have finished
C.can't have finished D.couldn't have finished
C,D同樣是對(duì)過去的否定判斷,句子中沒有時(shí)態(tài)應(yīng)該選C,為什么答案是D?請(qǐng)說明一下原因,
