Hespeaks lapanse very wellas if hewere a japanse
3if noly要是什么就好了onlyif只要
Wishthoughasif if only四者虚拟形式相同
Ifonly you hadlistened to me
4句1,or /otherwise,句2
Hurryup,otherwise,wewill belate.
现在例句ifmylivednow,he would giveusmore shows
过去例句ifqinghadnot goneback to qingdynasty,she would nothavemet him
下一个ifIhadbeenborn20 years earlier,Iwouldhavehadchanceto marryher
Iwished(that)Ihadmetjaychou
Would/could+do与将来相反
Iwish(that)theywould becomemyenemiesinthe future
三should+do的虚拟
Should可以省略在一些动词之后一个坚持二个命令四个建议四个要求一个宁愿 宁愿坚持建议命令要求一些动词之后+(that)+主+(should)+do
第二节介词短语仅代替从句without如果没有butfor要不是
Without me,what wouldyoudo ?本来应该为you would do但有what为疑问语气所以
Butforthe earthquakewe shouldnothavebought the salt crazily
Ifit hadnot been for其实就是withoutbut for与if作用一样
It isimportant that he (should)notcome
(should)不能省略itis (high|about)time that主+shoulddo该到做某事的时候了
Itishigh timethatweshould studyhard可以改成studied此句型中should do可以由该动词的一般过去式studied代替should dodied

一语法及基础知识第一节虚拟语气过去 现在将来
现在的为从句did原主句would shouldcouldmight +do
过去的从句为为had+did主句would could shouldmight +havedone
将来例句两个而且三字词提前了Iweretowin变成wereIto winIshouldwin变成
ShouldIwin qingchuan had not gonethe eighthsonofthe emperor
Have为实义动词时+n并且have不放在前面什么意思have为助动词时可以放在前面
被动语态be+donesuggest建议(should)do暗hatshewas(be)will
同源词用法相同suggestedtioningundesirable后面都是should+do一个词衍生好多个词,要掌握那一个词就行
2一个句型之后it isimportant/essential/ necessary/strange/natural /apity/ (should)do
5主句+lest免得/forfeer恐怕thatshould+do原型incase+that以防万一should+do此处should不可省略
可省略的情况should在1244之后长词important should+do(原)不省略should情况itis time
第二节倒装
将来的为从句为were to dodid wereshould+dodid主句为四大词+do
三个时态的虚拟分别于三个时间的事实相反
Wereshould had三个词可以提前放在一句话的第一位
判断将来时时注意关键的时间词现在时为now将来时为tomorrow
IfIhadtime ifqinghadgone
四其他类型虚拟语气1would rather11do12do ratherthando宁愿做而不愿意做13that+主语+did1与现在或将来相反21had gone与过去相反
Iwould ratherthat he had notheardit.
2主句+asif/though+主语+动词
现在did/were过去hadgone将来w/c+do
Prefer
Insist
Suggestadviseproposerecommend
Ordercommand
Require request demanddesire
注意insist后面要求应是shoulddo如果后面是认为 断言的意思后不虚拟
Thedoctorinsisted thatthe boywas(be)badlyhurtandinsisted thatheshould besent(send)to the hospital at once
第三届错综时间条件句 前后时间不一致
Ifyouhad taken my advise you wouldbe betternow有明显的时间状语
二表示愿望的虚拟为不可能实现的事
Hope可以实现的愿望wish不可以实现的愿望
Wish+that +主语+与现在过去将来事实相反
例子Iwish (that)从句everydayweremybirthday现在的
Otherwise前面的和后面的如果都是真实情况就不虚拟
He wasvery busy,otherwise,hewouldhave helpedyou 前面真后面假虚拟
两种用法1would+v原型与现在或将来相反2would +havedone与过去相反
过去好说一半或将来前面的was变后面的will跟着相应的变化不?
