2、Here she comes.她来了。二、现在进行时 1.表示正在进行的动作。2.表示按计划安排即将发生的动作。例如:She is leaving for Beijing.她要去北京。He is working as a teacher tomorrow.从明天起他要做老师。My father iscoming to see me this Saturday.这个星期六我爸爸要来看我。3.代替一般现在时,描绘更加生动。例如:The Changjiang River isflowing into the east.江水滚滚向东流。The sun is rising in the east.太阳从

4、,往往和“for”,“since”表述的一段时间状语连用。例如:He has learned English for six years./Theyhave worked here since they left college.3.现在完成时与一般过去时的区别:1)用两种时态来表述发生在过去的某一动作,现在完成时强调这一过去动作对现在产生的影响或结果,而一般过去时只表达过去的动作或状态,和现在关系不大。例如:She has cleaned the room.Its very clean now.(此句 has cleaned就不能改为 cleaned.一是因为 cleaned 与现状无关,二
5、是因为一般过去时不可突然跳到 Its这样的一般现在时。)2)汉语中的“了”、“过”、“曾”等词常用完成表达,如:I have seenthat film.(我看过那部电影了。)但是如果是在特定的过去时间“看了”、“做过”,就不可用完成时而必须用一般过去进来表达。例如:When did you see thatfilm?I saw it yesterday.(你什么时候看了那部电影?我昨天看的。)不能说:-When have you seen that film?I have seen it yesterday.4.表示“曾经到过某地(人已回来)”用“have/has been to”,表示“到
6、某地去了(还未回来)”用“have/has gone to”.例如:Where is Li Hua?He has gone to the reading-room.She knows a lot about Shanghai.She has been there.5.短暂动词(即瞬间动词),join,lose,buy,borrow,leave,go,come,arrive,die,marry,finish,complete,begin,start,break out 等,在完成时态中,其肯定式不能和表示一段时间的状语连用。例如不能说:He hasfinished the work for th
7、ree hours.要翻译“他已完成工作三小时了。”可采用 1)“ago 法”:He finished the work three hours ago.2)“延续法”:He has been through(with)the work for three hours.3)“since 法”:It is/hasbeen three hours since he finished the work.四、现在完成进行时 1.用来表示从过去某一时刻开始一直持续到现在(或今后还要继续一去)的动作。例如:He has been doing the maths problems since 8:00./I
8、t hasbeen raining for two days.2.凡是不能用于现在进行时的动词均不能用于现成完成进行时。五、一般过去时表达特定的过去时间内发生的动作或存在的状况,或过去某一时间内经常发生或反复发生的动作或行为。六、过去进行时 1.表示过去某一时刻或某一段时间内正在进行的动作(这一过去时间须用时间状语表示)。例如:He was preparing his lecture all day yesterday.2.表示动作在另一过去动作发生时进行。例如:They were still workingwhen I left.3.用在两个过去进行时动作同时发生。例如:I was writ
9、ing while he waswatching TV.4.表示过去将来动作。例如:He said she was arriving the next day.七、过去完成时 1.表示在过去某一时间以前已经完成的动作。例如:He had shut the doorbefore the dog came up./Everything had been all right up till this morning.2.表示动作或状态从过去某个时刻开始一直延续到另一个过去时刻才完成,甚至还要继续下去。例如:At the age of ten,he had learned 500 Englishwor
10、ds.He had been ill for a week when we learned about it.3.常用 hope,expect,think,intend,want,suppose 等动词的过去完成时来表示未实现的希望、打算或意图。例如:We had expected that you would beable to win the match.八、一般将来时一般将来时表示将来要发生的动作和存在的状况。有下列一些形式:-1.will/shall do(侧重将来行为,不突出计划安排去做某事)2.be going to do(主观上打算或客观上可能发生)3.be doing(按计划将
11、要发生,常和表示最近的将来时间连用)4.be about to do(按计划即将发生)九、将来完成时用来表示在将来某个时刻(前)将完成的动作。常和 by 短语,when,before引起的时间状语连用。例如:We will have finished senior Book 2 by the endof this term.时态考点分析1Can I join your club,dad?You can when you_a bit older.(NMET)A.get B.will get C.are getting D.will have got析:“You can”是将来意,when 引导的
12、时间状语从句要用一般现在时表将来所以此题答案为 A.2Oh,its you!I_you.Ive just had my hair cut and Im wearing new glasses.A.didnt recognizeB.hadnt recognizedC.havent recognizedD.dont recongnize析:从“Oh,its you!”可知说话时已认出对方。“没有认出”是在此之前为过去情况,所以应选 A.3.I dont think Jim saw me;he_into space.(NMET)A.juststaredB.wasjuststaringC.hasjus
13、tstared D.had just stared析:在空白处应选一个与“saw”相配,能解释 Jim didnt see me 这一原因的选项,只有着眼于 A、B。若选 A 不能体观他“当时正在做”某事,故排除 A 而选 B。这样因为“他正在望宇宙天空”所以“未看到我”。4._my glasses?Yes,I saw them on your bed a minute ago.(NMET)A.Do you see B.Had you seen C.Would you seeD.Have youseen析:现在完成时可表过去发生的事情对现在产生的影响或结果,问话人以这样的时态发问可作现焦急的心
14、情。故答案为 D。5.You dont need to describe her.I_her several times.(NMET)A.had met B.have met C.met D.meet析:答案 B。道理同 4。6.Do you know our town at all?No,this is the first time I_here.-A.was B.have been C.came D.am going析:根据 this/it is the first/second/time sb.has done sth.句型,可定答案为 B。又如:This is the second t
15、ime he has visited the Great Wall.7.Idon treallyworkhere.I_untilthenewsecretaryarrives.(NMET)A.just help out B.have just helped outC.am just helping out D.will just help out析:根据 I dont really work here.以及until the new secretary arrives,可知说话人所要做的事是计划安排行为,C、D 两个选项都表将来动作,但 D 非计划安排,C 则体现按计划去做,所以此题答案为 C。
16、8.Is this raincoat yours?No,mine_ there behind the door.(NMET)A.is hanging B.has hung C.hangs D.hung析:此题的“悬挂”是指现状而言,故表过去“挂”的 B、D 项可排除。C 项虽指“现在挂”,但侧重在常规,习惯。为了突出“你所指的那件雨衣不是我的,我的正挂在门后”这一意思,选 A 是极为合情理的。被动语态一、被动语态的句型 1.常见句式是:主语(受动者)be过去分词(by施动者)例如:He was scolded by the English teacher.2.主语get过去分词其它成分例如:T
17、he boy got drowned last summer./She got fired because of her faults.注意:使用这种结构不能带有“by施动者”3.带有双宾语(直接宾语和间接宾语)的主动句变为动句,其主语可以是直接宾语,也可以是间接宾语。例如:She lent me a bike.被动:1)I was lenta bike(by her).2)A bike was lent to me(by her).4.情态动词be过去分词例如:This problem must be worked out in half an hour.5.双重被动式:主语被动式谓语不定式
18、的被动式其它成分例 如;Thesemagazinesarenotallowedtobetakenoutofthereading-room./The murderer was ordered to be shot.二、主动表示被动的几种情况 1.不及物动词与状语连用,用以表示主语的品质和状态。常见动词是:cut,sell,read,write,fill,cook,lock,wash,drive,keep 等。例如:This knifecuts well.这把刀好切。These books sell well.这些书好卖。The pen writessmoothly.这支笔写起来流畅。Meat w
19、ont keep long in such hot weather.肉-在这样热的天气里放不长久。The cloth washes well.这种布好洗。2.一 些 连 系 动 词 的 主 动 式 形 容 词。常 见 动look,smell,taste,sound,feel,prove,turn out 等。例如:The apples tastegood./Theflowersmellswonderful./Thenewsproved/turnedouttrue./Cotton feels soft.注:prove 也可用于被动式,如:His answer(was)proved right.3
20、.不定式在某些形容词之后,且与主语有动宾关系。常见形容词有:hard,defficult,easy,heavy,fit,good,comfortable,convenient,impossible等。例如:The problem is easy to do./The question is difficult toanswer./The box is heavy to carry./The project is impossible to completein a year.比较:The problem is to be done./The question is to be answered
21、.没有形容词时,虽然不定式与主语是动宾关系,但必须用被动式。三、容易误用被动语态的几种情况:1.I teach myself French.不可变为 Myself is taught French.因为反身代词不可作主语。2.We help each other/one another.不可变为 Each other/One anotheris helped by us.因为相互代词不可作主语。3.He lost heart.不可变为 Heart was lost by him.因为象 loseheart,make a face,keep silence,lose in thought 这类动
22、宾结构的固定短语只能用于主动式,不能用被动式。4.She took part in the sports meet.不能变为 The sports meet was takenpart in by her.因为象 take part in,belong to,own,have,hate,fail,contain等表状态动词没有被动语态。被动语态考点分析1.I need one more stamp before my collection_.(NMET)A.hascompletedB.completesC.hasbeencompleted D.is completed析:complete 是及
23、物动词,“邮集”是被人完成的,须从表被动意的 C、D 中选择。又因 before 等引导的时间状语从句中谓语要用一般现在时表将来,所以此题答案为 D。2.Do you like the material?Yes,it_very soft.(NMET)A.is feeling B.felt C.feels D.is felt析:观察题干,空白线后无宾语,可知 feel 是不及物动词,表“(某物)摸起来”意思,是连系动词,不能用于被动式,也不用进行时。根据此题对话情景,是指某种材料的常规特性,要用一般现在时,不能用过去时,故答案为 C。feel作“感觉”、“认为”、“摸”等意时是及物动词,可带宾语
24、,有时态,语态等-变化。3Greatchanges_inthecity,andalotoffactories_.(NMET)A.have been taken placehave been set upB.have taken placehave been set upC.have taken placehave set upD.were taken placewere set up析:take place(发生)是不及物动词,不可用于被动语态,于是可排除 A、D,又因 set up(建造)是及物动词,在此题中应该用被动式,故排除 C,答案为 B。4.Mostoftheartists_toth
25、epartywerefromSouthAfrica.(NMET)A.invited B.to invite C.being invited D.had beeninvited析:首先可排除 B。因为它不表示“被邀请”。又因 D 项少引导词 who,也应排除。A 项who were invited,C项who were being invited,由象 invite 这类短暂动词的现在分词被动式不可作后置定语,故也应排除。因而可定答案为 A。5.I dont know the restaurant,but its_to be quite a goodone.(NMET)A.said B.told
