意见 文理分科指导河道管理范围浙江建筑工程概算定额教材专家评审意见党员教师互相批评意见 。e.g.Whatshallwedothisevening?2)shall用于第二、三人称，。e.g.Youshallfailifyoudon’tworkhard.(警告)HeshallhavethebookwhenIfinishit.(允诺)Heshallbepunished.(威胁)-Excuseme,butIwanttouseyourcomputertotypeareport.--YouAhavemycomputerifyoudon'ttakecareofit.A.shan'tB.mightnotC.needn'tD.shouldn't3）shall用于第一，第三人称疑问句中，。e.g.Shallwebeginourlesson?Whenshallwebeabletoleavethehospital?4）should,oughtto表示“应该”，oughtto表示义务或责任，比should语气重。e.g.Ishouldhelpherbecausesheisintrouble.Yououghttotakecareofthebaby.5)表示劝告、建议和命令。should,oughtto可通用，但在疑问句中常用should。e.g.Youshould/oughttogotoclassrightaway.ShouldIopenthewindow?6)should表示主观推测，“估计”“按道理应该”e.g.Heoughtto/shouldbehomebynow.Theyshouldfinishitbynow.7）“should+havedone”用于虚拟语气，表示。e.g.Youshouldhavearrivedhere5minutesearlier.8）特殊用法：“竟然”“居然”表示说话人感到意外，赞叹，愤怒，惊异等感情。e.g.Youcan’timaginethegentlemanshouldbeathief.e.g.我不知道为什么你竟然认为是我做的。“倒是”，用于第一人称时表示说话人的一种谦逊，客气，委婉的语气。e.g.Ishouldthinkitwouldbebettertotryitagain.Ishouldadviseyounottodothat.六、will,would1)will表示请求、建议等，would更委婉。e.g.Will/Wouldyoupassmetheball,please?2)will表示意志、愿望和决心。e.g.Iwillneverdothatagain.Theyaskedhimifhewouldgoabroad.3)would表示过去反复发生的动作或某种倾向。would表示过去习惯时比usedto正式，且没有“现已无此习惯”的含义。e.g.Duringthevacation,hewouldvisitmeeveryotherday.Thewoundwouldnotheal.4)would表示估计和猜想。e.g.Itwouldbeaboutteno’clockwhenshelefthome.5）would用在虚拟语气中（参考虚拟语气语法）。e.g.Ifitshouldrain,thecropwouldbesaved.七、情态动词+不定式完成式（havedone）1)can/could+havedone在肯定句中表示“本来可以做而实际上未能做某事”，是虚拟语气；在疑问句或否定句中表示对过去行为的怀疑或不肯定,表示推测。e.g.Youcouldhavedonebetter,butyoudidn’ttryyourbest.（虚拟语气）Hecan’thavebeentothattown.（推测）Canhehavegotthebook?（推测）2)may/might+不定式完成式（havedone）表示对过去行为的推测。不能用于疑问句中。might所表示的可能性比may小。e.g.Hemaynothavefinishedthework..Ifwehadtakentheotherroad,wemighthavearrivedearlier.3）must+不定式完成式（havedone）用于肯定句中，表示对过去行为的推测。意为“一定、想必”。其疑问、否定形式用can，can’t。can/could+havedone表示推测。e.g.YoumusthaveseenthefilmTitanic.HemusthavebeentoShanghai.4）should+不定式完成式（havedone）用于肯定句中，表示对过去行为的推测。e.g.Heshouldhavefinishedtheworkbynow。表示“本应该做而实际上没有做某事”，其否定式表示某种行为本不该发生却发生了。可以与oughtto+不定式完成式（havedone）互换。e.g.Yououghtto/shouldhavehelpedhim.(butyoudidn’t.)Sheshouldn’thavetakenawaymymeasuringtape,forIwantedtouseit.5)needn’t+不定式完成式（havedone）表示“本来不必做而实际上做了某事”。e.g.Youneedn’thavewateredtheflowers,foritisgoingtorain.6)will+不定式完成式（havedone）主要用于第二、三人称，表示对已完成的动作或事态的推测。e.g.Hewillhavearrivedbynow.Hedidnotpasstheexamination.Asagoodstudent,he　B　.　A.mustn'thavefailed　B.maynothavefailedC.needn'thavefailed　D.shouldn'thavefailedII虚拟语气1、虚拟语气用在简单句中，表示“强烈的祝愿或命令的语气”。常用“May+主语+动词原形”或“主语+动词原形”。例如：祝愿我们的友情天长地久。Yougoout！你出去！2、虚拟语气在宾语从句中的用法。由及物动词wish引导的宾语从句常表示说话人的一种强烈的却暂时无法实现的愿望。我多么希望她能站在我一边啊！我多么希望我能帮助他啊！HowIwishIhadwatchedthecloseNBAgamelastnight.另外，在表示“命令”、“坚持”、“要求”或“建议”等意义的及物动词（order,command,demand,require,insist,suggest,propose,advise）之后的宾语从句中的谓语动词同样常使用虚拟语气，表示说话人的要求，其结构为：主语+should+动词原形，其中的should常可省略。例如：Theheadteacherdemandedthatwe(should)finishthetaskintimetoday.注意：insist作“坚持”说时，要用陈述语气；作“坚决主张；坚决要求”讲时，用虚拟语气。suggest表示“暗示”或“表明”之意时，宾语从句用陈述语气，表示“建议”时，用虚拟语气。试比较：我父母坚持我应该上重点大学。Myparentsinsistedthattheyright.Thesoldier’spalefacesuggestedthathehappytohavegivenhislifetohismotherland.Themonitorsuggestedthatweaclassmeetingtomorrowafternoontodiscusstheproblem.3、虚拟语气用在主语从句中。在句型"Itisimportant(necessary,strange,natural,apity,suggested,advised,demanded,commanded,ordered)that...."中，that后面的从句中的谓语动词常用：“should+动词原形”。例如：我们有必要出去散散步。她这样做是很自然的。重要的是我们要照顾好病人。同理，在表示“命令”、“坚持”、“要求”或“建议”等意义的名词前后的主语从句、表语从句和同位语从句中的谓语动词同样用虚拟语气，既：“主语+(should)+动词原形”的句型。例如：Hissuggestion/adviceisthatweshouldstartearlytomorrowmorning.3、虚拟语气用在状语从句中。虚拟语气最多地用在表示条件的状语从句和表示结果的主句中。在表示与事实相反的虚拟语气时，动词有三种虚拟形式，即虚拟条件现在式，过去式和将来式。虚拟条件现在式：表示与现在事实相反的假设及根本不可能的假设或结果：条件状语从句主句If主语+动词过去式（be用were）2)虚拟条件过去式：表示与过去事实相反的假设或结果：条件状语从句主句主语+should/would/could/might+have+过去分词。3）虚拟条件将来式：表示与将来事实相反的假设或结果：条件状语从句结果主句主语+should/would/could/might+动词原形如果我是你，我就买了它。IfIhadtimenow,IwouldstudyFrench.如果我现在有时间，我会学习法语的。如果你早一点起床，就会赶上火车。如果明天天气好，我将和朋友们一起去买东西。4、有关虚拟语气的几个附加问题：1)有时if引导的状语从句可以省略if，而把条件状语从句中的动词were,had或should移到主语前面，使用部分倒装语序。例如：.如果她年青点，她就会干这件事了。.如果他知道她的地址，他会去看她的。要是明天能下雪的话，那就太棒了。有时表示虚拟语气的条件从句或者主句都可以省略，而只剩下一个主句或者一个条件从句。IfIhadtime.我要有时间该多好啊。Sheshouldhavecometotheparty.她应该来参加聚会。3)虚拟语气中，条件从句的动词动作可以和主句的动词动作时态不一致，这种句式就被称作为“混合虚拟条件句”。If+had+主语+过去分词，主语+should/would/could/might+动词原形Iftheyhard,theyiteasilynow.如果他们以前努力学习的话，现在干的就会容易些。Ifhemyadvice,heitmuchbetterlikethis.如果他不听取我的建议，他就不会干得这样好。4）特殊句型：It’s(high)time(that)sb.shoulddo/过去式Sb.wouldrather(that)sb+过去式5）含蓄虚拟条件句含蓄条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常来表示含蓄虚拟条件的手段有：（1）介词或介词短语，如butfor,butthat,without,incaseof,undermorefavorablecondition等。______B______theleadershipoftheparty,wecouldnotbelivingahappytoday.=Iftherehadn’tbeentheleadershipoftheparty,wecouldnotbelivingahappytoday.A.InspiteofB.ButforC.BecauseofD.AsforButthatshewasafraid,shewouldhavesaidno.6)虚拟语气用于asif（though）引起的方式状语从句和表语从句中，其动词形式与wish宾语从句的形式相同。eg：Sheoftenlaughsspontaneously,andhergoodhumorbreaksoutasbrightlyasifitwereapartofthesunshineabove.她常常发出发自内心的微笑，而且她那美好的情绪像天上一道明亮的阳光一样，常常流露出来。Theytalkedasiftheyhadbeenfriendsforyears.他们交谈着，就好
