PETS3 语法笔记PETS 语法辅导:虚拟语气16. 虚拟语气1) 概念虚拟语气用来表示说话人的主观愿望或假想,所说的是一个条件,不一定是事实,或与事实相反。

2) 在条件句中的应用条件句可分为两类,一类为真实条件句,一类为非真实条件句。

非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。

16.1 真实条件句真实条件句用于陈述语气,假设的情况可能发生,其中 if 是如果的意思。

时态关系句型: 条件从句主句一般现在时 shall/will + 动词原形If he comes, he will bring his violin.典型例题The volleyball match will be put off if it ___.A. will rainB. rainsC. rainedD. is rained答案B。

真实条件句主句为将来时,从句用一般现在时。

注意:1) 在真实条件句中,主句不能用be going to表示将来,该用shall, will.(错) If you leave now, you are never going to regret it.(对) If you leave now, you will never regret it.2) 表示真理时,主句谓语动词便不用shall (will) +动词原形,而直接用一般现在时的动词形式。

16.2 非真实条件句1)时态:可以表示过去,现在和将来的情况。

它的基本特点是时态退后。

a. 同现在事实相反的假设。

句型 : 条件从句主句一般过去时 should( would) +动词原形If they were here, they would help you.b. 表示于过去事实相反的假设。

句型: 条件从句主句过去完成时 should(would) have+ 过去分词If she had worked harder, she would have succeeded.The rice would not have been burnt if you had been more careful.If my lawyer had been here last Saturday, he would have prevented me from going.If he had come yesterday, I should / would have told him about it.含义:He did not come yesterday, so I did not tell him about it.If he had not been ill and missed many classes, he would have made greater progress.含义: He was ill and missed many lessons, so he did not make greater progress.c. 表示对将来的假想句型: 条件从句主句一般过去时 should+ 动词原形were+ 不定式 would + 动词原形should+ 动词原形If you succeeded, everything would be all right.If you should succeed, everything would be all right.If you were to succeed, everything would be all right.16.3 混合条件句主句与从句的动作发生在不同的时间,这时主,从句谓语动词的虚拟语气形式因时间不同而不同,这叫做混合条件句。

公共英语三级主要语法点

公共英语三级主要语法点

Dear同学们,以下是公共英语三级的主要九个语法点。

希望同学们有时间看看。

第一,虚拟语气。

第二,定语从句。

第三,反意疑问句。

第四,倒装句。

第五,主谓一致。

第六,强调句。

第七,连词的辨析。

第八,省略句。

第九,现在分词作状语。

第一,虚拟语气。

它主要可分为以下情况:A,表建议,要求,命令的动词,及与其相关的名词、形容词或分词,后面的从句中都要用should+动词原形作谓语,should可省略。

B,某些特殊的形容词,后面常跟虚拟语气。

这一点要尤其注意。

C,wish后表示与现实相反的愿望时要用虚拟语气。

D,would rather后若加从句则要用过去式表示虚拟语气,也可以直接加do sth宁愿做…。

E,If引导的条件状语中,表示与现在情况相反的假设,表示与过去情况相反的假设时。

虚拟语气这个考点在近两年当中出现的考分这两年稍微偏高,这一点尤其大家要格外的关注一些。

第二,定语从句。

这次考试对定语从句的考察是重点考察关系词选择和非限定性定语从句。

关系词的选择关键要从其在从句中担任着的成分决定的,而不是在主句中的。

非限定性定语从句通常由逗号与修饰的名词相隔开,而且只能由which,who,whom,whose引导,其中which既可以指物,也可以指前面一整句话,这一点大家一定要注意。

另外介词和上面的关键词连用构成符合关系词的情况也很多。

第三,反意疑问句。

可以有两点,句子本身含有否定意义的时候,比如seldom后面用肯定形式的反问。

第二,考察祈使句的反问,对陈述部分是肯定句的祈使句。

第三,I think,I believe,I suppose等表示主观看法的句子,其反意疑问句由后面的宾语从句相对应。

第四,倒装句。

倒装句一共有三项应该注意:A,only后面加状语,并放于句首时,句子用倒装;而当其修饰其它成分时不倒装。

B,表示否定意义的副词或短语,如seldom,never,rarely,in no time。

C,注意Hardly/scarcely/barely had sb done…when这一句型,表示一——就…(as soon as后不加倒装)第五,主谓一致。

全国英语等级考试pets3三级常见语法解析

2019 年全国英语等级考试 pets3三级常有语法分析(4)虚假语气表示与客观事实相反的假设,由 if 虚假条件从句和主句构成。

一、虚假语气的基本内容依照虚假与其这类与事实相反的假设所对应的时间不一样样,虚假语气的 if 虚假条件从句与主句的谓语动词分别有三类构成形式:假设种类If 虚假条件从句主句与现在事实相反Did/were Would/should do与过去事实相反 Had done Would/should have done与将来事实可能相反Were to do/did/should do Would/should do例: 1、I wouldn't talk that way if I were Peter.2、If the whole operation had not been planned beforehand, a great deal of time and moneywould have been lost3、Jean doesn't want to work right away because shethinks that if she were to get a job she probably wouldn ’t be able tosee her friends very often.4、I would ask George to lend us the money if I knew him.5、Do you think there would be less conflict ( 战斗、斗争) in the world if all people spoke the same language.6、If Bob had come with us, he would have had a goodtime.二、 if 的省略形式( 又称虚假语气的倒装结构)在if 虚假条件从句中,若是谓语部分包含were,should ,had等词,则能够把这些词放到主语前,省略 if ,构成虚假语气的倒装结构。

语法:情态动词情态动词是表示有能力、义务、必要、猜测等说话人的语气或情态等的词类。

所表示的情态包括命令、请求、愿望、拒绝、可能、需要、敢于等。

情态动词本身有一定的意义,但不完全,不能单独作谓语,只能和不带to的动词不定式(ought等除外)一起构成复合谓语。

情态动词有:can/could, may/might, shall/should, ought/ought, will/would, must/must、need/needed, dare/dared, have(has) to/had to, used to等。

三级统考中,重点不是考试情态动词+原形动词,重点是考试下面四种比较复杂结构:1、must have done表示对过去的动作比较有把握的猜测。

如The road is wet.It must have rained last night.地是湿的,昨晚一定是下雨了。

另外,may have done 也表示对过去事实的猜测,但可能性比较小。

如He isn’t here yet.He may have forgotten about the meeting.他还没来,可能是忘了这次会议了。

2、should (not) have done / ought (not) have done表示过去应当做的动作由于某种原因没有做到,含有责备之意,其中should (not) have done语气较重一些。

如:You should have got up earlier.你本来应该早起的。

She ought to have seen a doctor about her headache a week ago.她本应一周前去看头痛病的。

3、would have done也表示过去没有实现的动作,与should have done 相比,would have done不可以单独使用,必须和虚拟语气中的条件从句连用;再者should have done有批评意味,而would have done没有批评意味。

;第一节动词的时态一、一般现在时:1、由when、as soon as、the minute、the moment、till、until等引起的时间状语从句,以及由if、unless、provided that等引起的条件状语从句常常用一般现在时态表示将来的动作,而主句则用一般将来时态。

例:They will go home for winter vocation as soon as they finish their exams.2、当表示普遍的真理或者众所周知的客观事实,常常用一般现在时态。

例:The earth is round. 地球是圆的。

二、一般过去时:区分三个短语的用法:1、used to do sth:过去常常做某事。

2、be/get used to doing sth:习惯做某事。

,3、be used to do sth:被用于做某事。

三、一般将来时:1、be to+动词原形:表示安排或计划好了的动作。

例:The Third-Ring Road is to be open to traffic before National Day.2、be about to+动词原形:表示即将发生的动作。

例:The lecture is about to begin.讲座即将开始。

3、一些表示动作趋势,如开始、终结,以及一些表示动作方向,如往来的动词,常常用现在进行时态表示按照安排将于将来发生的事情,这类动词常见的有如:start,go,leave,come,arrive等。

例:We are leaving for Beijing tomorrow. 我们明天动身去北京。

四、进行时态:重点区分when和while引起的时间状语的用法。

When表示时间上的点,在考试中其引导的时间状语从句多翻译为“这时”,主句多用进行时态;while引导的时间状语从句多翻译为“正当……时”,该从句用进行时态。

例:One of the guards was sleeping when the general came in, which made him very angry.'I fell and hurt myself while I was playing tennis.五、现在完成时:重点区分have (has) been to:某人去过某地,表示一种经历,强调状态,可以和once,twice,often,never,ever连用;Have (has) gone to:某人在去某地的途中或已在某地,强调动作。

此句型不能与上述时间状语连用。

例:He has gone to America.他已经去了美国。

He has been to America twice.他去过美国两次。

六、过去完成时:1、强调一个动作发生在另外一个过去的动作之前时,用过去完成时。

2、It was the first/second/last time that 在该句型,that从句用过去完成时态。

七、将来完成时:)常常标志性地由by、by the time、by the end of引起一个表示将来时间段的时间状语,主句用将来完成时态。

第二节感官动词、使役动词的用法及英语中常考的两个句式结构一、感官动词的用法及其被动语态:在英语中,常见的感官动词有“五看二听一感觉”(see、watch、look、notice、observe;hear、listen to、feel),在主动语态中用动词原形或现在分词作宾补,如see sb do/doing sth,改为被动语态时则要加to,如sb be seen to do sth.二、使役动词的用法及其被动语态:在英语中,常见的使役动词有make、let、have,在主动语态中用动词原形做宾补,如make sb do sth,改为被动语态时则要加to,如sb be made to do sth,两种形式都表示使/让某人做某事的意思。

例:We were made to study hardy.我们被要求努力学习。

三、英语中常考的句式结构一:sth need/ want/ require doing 某物需要(=sthneed/want/require to be done)(此句式主语为物)例:My room is a mess. It needs tidying up (整理)。

四、英语中常考的句式结构二:have/get sth done 请/让别人做某事(have/get后接宾语为物)例:I have taken many photos. I‘m going to get the filmdeveloped. 五、情态动词的被动语态,其构成为:情态动词+be+过去动词。

例:The work must be finished before lunch. 这项工作必须在午饭前干完。

第三节情态动词[常见的情态动词有can、could;may、might;must、need;should;ought to,对于情态动词常考其两方面的内容,一是情态动词用于推测句型,二是情态动词用于虚拟语气(该部分的讲解放在虚拟语气)一、情态动词用于对现在内容推测的常见句型有:1、Can/may do sth:表示对现在内容的可能性的推测;2、Must do sth:表示对现在内容的肯定性的推测。

二、情态动词用于对过去内容推荐的常见句型:1、can/may have done sth:表示对过去内容的可能性;2、must have done sth:表示对过去内容的肯定性的推测。

例:1、Mr Green must have failed to receive my letter, otherwise he would have replied.。

2、I believe he must have had an accident, otherwise he would have arrived on time.第四节虚拟语气虚拟语气表示与客观事实相反的假设,由if虚拟条件从句和主句构成。

一、虚拟语气的基本内容根据虚拟与其这种与事实相反的假设所对应的时间不同,虚拟语气的if虚拟条件从句与主句的谓语动词分别有三类构成形式:假设类型If虚拟条件从句主句与现在事实相反 Did/were Would/should do 与过去事实相反 Had done Would/should have done 与将来事实可能相反 Were to do/did/should do Would/should do例:1、I wouldn't talk that way if I were Peter.》2、If the whole operation had not been planned before hand, a great deal of time and moneywould have been lost3、Jean doesn't want to work right away because she thinks that if she were to get a job she prob ably wouldn’t be able to see her friends very often.4、I would ask George to lend us the money if I knew him.5、Do you think there would be less conflict (战斗、斗争) in the world if all people spoke the same language.6、If Bob had come with us, he would have had a good time.二、if的省略形式(又称虚拟语气的倒装结构)在if虚拟条件从句中,如果谓语部分包含were,should,had等词,则可以把这些词放到主语前,省略if,构成虚拟语气的倒装结构。

\三、主句与从句时间不一致时虚拟语气的构成当虚拟语气的if虚拟条件从句和主句的动作发生的时间不一致时,要根据各自表示的时间采用对应的虚拟语气的构成形式。

例:1、If I had attended the meeting yesterday, I would know what happened now.2、If you had taken our advice at that time, you would not be in trouble now.四、主观倾向性动词引导的虚拟语气的构成在英语中存在一些动词,表示建议、命令、要求等主观的倾向,由这些动词引导的that宾语从句中,从句的谓语动词要用should+动词原形,should可以省略。

这类常见的主观倾向性动词有“一坚持、二命令、三建议、五要求”,分别是:一坚持:insist 二命令:order、command 三建议:suggest、advise(n advice)、propose(提议、建议)五要求:ask、demand、require、request、desire例:1、The doctor advised that Mr. Malan have an operation right away so as to save his life.;2、His mother insisted that he put on the coat when going out. 同时,如果在题干中出现上面这些主观倾向性动词的名词和形容词形式,题干中从句部分的谓语动词也要用should+动词原形,should可以省略。

考试中常见的词汇有:order,command,suggestion,advice,proposal,demand,request,desire,advisable,desirable.五、wish that和if only引导的虚拟语气的构成Wish that引导的宾语从句和if only引起的感叹句都用虚拟语气来表示一种没有实现或无法实现的愿望,其中wish that句型往往翻译为:多么希望;if only表示的愿望较wish that更强烈,常翻译为但愿;要是就好了。

两者的用法基本相同。

两者的用法是:1、当表示与现在的事实相反的一种愿望时,wish that引导的宾语从句和if only引起的感叹句中谓语动词采用的形式是:did/were;2、当表示与过去的事实相反的一种愿望时,wish that引导的宾语从句和if only引起的感叹句中谓语动词采用的形式是:had done;3、当表示未来一时很难实现的一种愿望时,wish that引导的宾语从句和if only引起的感叹句中谓语动词采用的形式是:would do.六、would rather引导的虚拟语气的构成Would rather的意思是“宁愿、宁可”其引导的宾语从句(一般省去that)通常用虚拟语气表示一种与事实相反的假设。
