Question

求助虚拟语气各种情况的例句举例和解析~

Answer 1

第一步：掌握对现在,对过去,对将来的虚拟的固定时态
对现在的虚拟：
If he were free,he would help us.要是他有空的话,它会帮助我们的.
注意,虚拟中的is,都用were
注意,主句用would +动词原型,从句用过去式
对过去的虚拟
If I had seen the film,I would have told you about it.我如果看过这场电影,我会把电影内容告诉你了
注意时态：主句用would +现在完成时,从句用过去完成时
对将来的虚拟
If he were to come here,he would tell us about it.
如果他要来的话,他会通知我们一声.
或,if he came here...
if he should come here.
主句用would +动词原型,从句分三种：过去式,were to,should
第二步：掌握错综虚拟,即主从句的动作（看时态提示词）,有错综
If he were free today,we would have sent him to Beijing.
如果他今天有空的话,我们会已经派他去北京了.
本来主句用了would +现在完成时,说明是对过去氏好凳的虚拟,从句本来应该用过去完成时,但是,由于从句中有个时态提示词,today,则套用对现在的虚拟的公式,用过去式
If he had been working hard,he would be working in the office now.
要是他工作一直努力的话,他现在已进了办公室了.
从句用了过去完成时,说明死对过去的虚拟,本来主句要用would +现在完成时,可是,主句里有个时态提示词,now,则主句套用现在的虚拟,用would +动词原型
这样根据主袜姿句,从句不同的时态,针对不同时间的虚拟,叫错综虚拟
第三步,含蓄虚拟语气,就是把if 省略,用倒装
Were she here,she would agree with us.如果她在这儿的话,她会同意我们的.
=if she were here,she would agree with us
第四步,虚拟语气再名词性从句中的应用
对于表建议,命令,要求的词,虚拟比较固定,一律用should +动词原型,但是should 可以省略
advise,ask,demand,desire,decide,insist(坚决要求) ,order,
propose,request,suggest(建议) 表示请求、要求、命令或建议歼旅等意义的动词所接的宾语从句一般用虚拟语气,其虚拟语气的结构为：(should) + 原形动词.如：
The teacher advised that we （should） make good use of every minute here.
老师劝我们要好好地利用在这儿的每一分钟.
