虚拟语气的练习题
Should it rain,the crops _____ .
A.would be saved B.would have been saved
C.will be saved D.had been saved
这题为什么选A?should可以表示“万一”,那么下雨就可能是真实条件,为什么不选C呢?庄家能被救到,下雨这个条件可以看做真实条件啊.
What should we do if it _____ tomorrow?
A.should snow B.would snow C.snow D.will snow
这题选A,同问为什么!天哪,该死的虚拟语气啊!
最后还有这题,--- “What will you do during the summer holiday?”
--- “I don’t know,but it’s high time _____ something.”
A.I’m deciding B.I’ll decide C.I decided D.I decide
为什么选C呢?为什么不选D啊!从句should+原型...
可是在从句中should不是可以省略吗？为什么要用动词过去式而不是动词原型呢？我指第三题
另外第一二题我也知道是跟将来事实相反，但是为什么这两句不可以被看成是真实条件句呢？

第一题：
与将来事实相反
条件句结构：
动词用过去式
were to 加动词原形
should 加动词原形
主句结构
should＋动词原形
would＋动词原形
第二题同一
第三题：
It is time that+主语+should+动词原形
It is time that+主语+动词过去式
都是一些死的语法,确实很头痛的,希望对你有用.
should如果可以省略,你觉得
It is time that+主语+should+动词原形
It is time that+主语+动词过去式
上面两句会不会有矛盾?
其实,这些语法的东西,基本套框框.
工作后你会发现没什么用的.
只是学生时代考试有用.
