高中英语语法- 动词时态-- 完成时

高中英语语法: 动词时态－－完成时完成时完成时是用来表示动作的完成与未完成的情况。

完成时包括现在完成时、过去完成时和将来完成时。

A．现在完成时．现在完成时的构成现在完成时的构成形式是“have / has +过去分词”。

现在完成时常被称为“与现在有联系的过去”，因此它不能与明确的过去时间状语连用。

as bwindow.有人把窗户打破了。

I haven'ulately.我最近不常见到她。

How long have they been married?他们结婚多长时间了？．现在完成时的用法①表示结果的现在完成时现在完成时着眼于过去的动作对现在产生的结果或影响。

这是现在完成时的“已完成”用法，表示动作或过程发生在说话之前就已完成，并与现在有联系。

这种联系实际上就是“过去的动作”对现在的影响或产生的结果。

I have bought a我买了一支笔。

（结果：I have apen now.）Tature has increased by 10℃.温度上升了10摄氏度。

（结果：It is quw.）Air pollution has talives of many people.空气污染已经夺去了很多人的生命。

（结果：Air polluvus now.）注意：现在完成时的上下文所指的时态必须呼应。

【误】I have bought a pen but I have lw.（have bought表示你现在已经有笔了，这和后面的have lost 有矛盾）【正】I bought a pen but I have lw.我（过去）买了一支笔，但我已经把它丢了。

【误】I have lbut I have found it now.（have lost 强调你现在已经没有笔了，与后面have found的意思有冲突）【正】I lbut I have found it now我丢了一支笔，但现在已经找到了。

②表示经历的现在完成时强调过去某一时刻到说话时这段时间中的经历。

thought.现在分词短语有时可以用作状语表示原因,相当于一个表示原因的状语从句.get in touch with her.Not knowing her address,we couldn’ｔSeeing nobody at home,she decided to leave them a note.want to go to the cinema.Having already seen the film twice,she didn’ｔ现在分词短语有时可用作时间状语,相当于when引起的从句:help thinking of those memorable days they spent together.Seeing those pictures,he couldn’ｔ如果两个动作是完全同时发生的,多用when或while加分词这种结构.Be careful when crossing the street.When leaving the airport,they waved again and again to us.She got to know them while attending a conference in Beijing.3)前面带有代词或名词的动名词结构:一个动名词前面可以加一个物主代词(或名词的所有格结构),来表示这个动名词逻辑上的主语.Their coming to help was a great encouragement to us.Our sole worry is your relying too much on yourself.Do you mind my reading your paper?They insisted on my staying there for supper.如果不是在句子开头,这个结构常常可以用名词的普通格(或人称代词宾格),这比用所有格更自然一些.I don’ｔm ind him going.She hates people losing their temper.help,mind,admit,enjoy,leave off, 4)只能用动名词作宾语的动词:suggest,finish,avoid,stop,can’ｔrequire,postpone,put off,delay,practise,fancy,excuse,pardon,advise,consider,deny,endure,

jewels,newly-arrived visitors用作后置修饰语的过去分词一般都带有修饰语或其他成分,在意义上相当于关系分句.Most of the people invited to the reception were old friends.2)句法作用a)作定语:distinguished guest贵宾,unknown heroes无名英雄,armed

after40or50years.d)独立结构:在用分词短语作状语时,它逻辑上的主语一般必须与句子的主语一.致.但有时它也可以有自己独立的逻辑上的主语,这种结构称为独立结构,一般表示一种伴随的动作或情况.He rushed into the room,his face covered with sweat.有时可以表示时间:Late that autumn,his work finished,he prepared to return to his institute.表示原因:Her eyesdimmed with tears,she did not see him enter.条件:All things considered,her paper is of greater value than yours.Ⅲ虚拟语气1.that从居中:1)wish,would

requirement is(was)that thy system be adjusted.2.在某些句型中1)it is time thatIt is time that we went(或should go)to bed.It is high time we(should)put an end to this controversy.2)as if(though)引起的从句:They talked(are talking)as if they had been friends for years.It seems as if it was(were)spring today.He acts(acted)as if(though)he were(was)an expert.3)以lest,for fear that和in case引起的从句(这时谓语多用should+动词原形):He took his raincoat with him lest it should rain.He put his coat over the child for fear that(或lest)he should catch cold.I’ll keep a seat for you in caseyou should needit.4)以whatever,whoever,no matter what这类代词或词组引起的从句(这时,谓语多用may加动词原形构成):Whatever defects he may have,he is an honest man.Come what may,we will go ahead.不管发生什么情况,我们都要干下去.I accept that he is old and frail;be that as it may,he’ｓs till a good politician.我承认他年老体衰,然而尽管如此,它仍是优秀的政治家.3.条件句1)虚拟条件句主要有下面两类:a)表示现在及将来情况(表示纯然假设或实现的可能性不大的情况):谓语主要形式如下(be多用were这个形式):从句主句过去式would+动词原形If I were you,I wouldn’ｔl ose

more votes,he would be our chairman now.got everything ready by now,we should be having a terrible time tomorrow.If we hadn’ｔ3)有时假设的情况并不以条件从句表示,而是通过一个介词短语来表示.Without music,the world would be a dull place.We could have done better under more favorable conditions.That would have been considered miraculous in the past.But for the storm,we should have arrived earlier.4)如果条件句从句中包含有were,had,should或could,有时可把if省略掉,并把were,had,should或could放在主语前面.Had we made adequatepreparation,we might have succeeded.Should there be a flood,what should we do?Were it not for

girl(who/that)I spoke to is my cousin.2)限制性定语从句如果修饰“物”,用关系代词that的时候较多,也有时用which..当这个代词在从句中是用作宾语时,在绝大多数情况下都是省略的,特别是口语中(尤其是当被。
