9、于否定句和疑问句和条件状语从句中。当句中含有任何的意思时，any可用于肯定句。Here are three novels.You may read any.这有三本小说，你可任读一本。五、one,ones 为复数形式 ones必须和形容词连用。如果替代的名词时无形容词在前，则用some,any，而不用ones。Have you bought any rulers?Yes，I ve bought some.Only在句首要倒装的情况 Only in this way,can you learn English well.Only after being asked three times did

10、 he come to the meeting.如果句子为主从复合句，则主句倒装，从句不倒装 Only when he is seriously ill,does he ever stay in bed.不定代词every、no、all、both、neither、nor的用法 1）不定代词有all,both,every,each,either,neither,more,little,few,much,many,another,other,some,any,one,no 以及some,something,anything,everything,somebody,someone,anybody,a

14、。May God bless you!He might be at home.注意：might 表示推测时，不表示时态。只是可能性比may 小。2）成语：may/might as well，后面接不带to 的不定式，意为不妨。If that is the case,we may as well try.典型例题 Peter _come with us tonight,but he isnt very sure yet.A.mustB.may C.can D.will 答案B.表可能性只能用may.此句意可从后半句推出。though,although的用法 注意：当有though,althoug

15、h时，后面的从句不能有but，但是 though 和yet可连用 Although its raining,they are still working in the field.虽然在下雨，但他们仍在地里干活。He is very old,but he still works very hard.虽然他很老，但仍然努力地工作。Though the sore be healed,yet a scar may remain.伤口虽愈合，但伤疤留下了。（谚语）典型例题 1）_she is young,she knows quite a lot.A.WhenB.However C.Although

17、 will,he never seems able to do the work satisfactorily.=Though he tries hard,he never seems虽然他尽了努力，但他的工作总做的不尽人意。3)ever if,even though.即使Well make a trip even though the weather is bad.4)whetheror-不管都Whether you believe it or not,it is true.5)no matter+疑问词 或疑问词+后缀everNo matter what happened,he would

18、 not mind.Whatever happened,he would not mind.替换：no matter what=whateverno matter who=whoeverno matter when=wheneverno matter where=whereverno matter which=whicheverno matter how=however 注意：no matter 不能引导主语从句和宾语从句。（错）No matter what you say is of no use now.（对）Whatever you say is of no use now.你现在说什么

19、也没用了。(Whatever you say是主语从句)（错）Prisoners have to eat no matter what theyre given,（对）Prisoners have to eat whatever theyre given.囚犯们只能给什么吃什么。从so do I 谈起 两人对话，乙方对甲方的问话常可用简短回答作出 反应。例如：Do you like it?-Yes，I do.这同样适用于陈述句的场合：You worry too much-No，I dont.在后一种情况下，乙方也能Sodo主语之类 的结构表示看法。例如甲方说我喜欢苹果，乙方 如果想表示我也喜欢

20、苹果，英语可以说：A：I like apples.B：So do I（I like apples，too。）这里的so在意义上相当于in the same way，即同样、也那样，作简短反应表示同样看法时常用之。就诸如此类的四种结构略作介绍。1Sodo主语结构 在简短反应中表示我也如此或另外一个人也 如此时，也就是主语不同于上文的主语以及上 文并无可用于构成倒装的动词（即操作词时），可用此结构。例如：A：I like playing football.B：So do I./So does my brother./So did my father.如果上文有可用于构成倒装的动词时，则用相同 的动

21、词或根据不同人称用同类的动词。I must go-So must I.John can speak French-So can I.Ive got a new car-So has John.She is clever.-So is he.2Neither/Nor do 主语 结构 如果上文表示否定意义而在简短反应中表示同样 看法时，可用此结构。例如，甲方说I cant swim，乙方如果想表示我也不会游泳，英语可以说 Neither can I./Nor can I（I cant either）。又例如：A：He doesnt speak French.B：Neither/Nor do I.

22、Neither/Nor does my brother.Neither/Nor does my father.关于以上两种结构，有两点说明：第一，能用动词缩略形式。例如：Im going to London.-Sos John。(is)Ive been to New York.-Sos John.(has)Id have gone to Tokyo if I could-Sod John.(would)John hasnt got a visa.-Norve do I(have)Jim and Mary arent acting in the college play.-Neithers Pe

23、ter.(is)第二，上述甲乙对话如用and连成一句可出自一人 之口。例如：John can speak French and so cant I.John cant speak French and neither/nor can I.John speaks French and so do I.John doesnt speak French and neither/nor do I.上述斜体部分相当于and I can,too/and I cant either/and I do too/and I dont either 的意思。3So主语do结构 在简短反应中，对别人所说的情况加以肯

24、定以及 主语与上文主语相同时，可用此结构，注意，这 里不用倒装同序；so 的意义相当于indeed,certainly，即不错、对了。例如：A：John smokes a lot.B:So he does(=He smokes a lot indeed.)这类简短反应往往带有说话人的惊奇口吻。例如：A：Look，its raining!B:So it is.在这里，So it is的含义是 You are right!It is raining；and this surprises me.more than的用法a)接名词，意为“不仅，不止”，有and的意思。He was more than

25、a scientist,but was a poet.他不仅是为科学家，还是个诗人。b)接数词，意为“.以上”。More than twenty people were injured in the accident.20多人在事故中受伤。c)接形容词，意为“非常，十分”。He was more than pleased with her performance.他对她的表演非常满意。d)接含can的从句，意为“如此.不能；.得不”。The beauty of the place is more than I can describe.那地方美得无法形容。e)接动词，意为“不仅是.而且还.”。

26、They decide to do more than talk about the rise of the cheating.主谓倒装句的应用主语和谓语是句子的核心，它们之间有两种语序：一是主语在谓语之前称为自然语序（Natural Order）；二是主语在谓语之后则称为倒装语序（Inverted Order）。而倒装语序中又有全部倒装（Full Inversion）和部分倒装（Partial Inversion）两种情况。首先，在全部倒装的句子中，要把整个谓语放在主语的前面去而构成倒装语序。例如：There are large numbers of students in the lect

27、ure hall.在There be的句式中，There只是个引导词而不是主语，真正的主语是后面作表语的名词或者名词短语。因此，There be的句式都是全部倒装的句子。）演讲厅里有大量的学生。When he ran to the door,there stood a mid-aged man with a lantern in his hand.（此句是为了描述情节的需要，把倒装当着修辞的手段而写成了全部倒装句。句子的主语是a mid-aged man，谓语是stood。）当他向房门跑去时，那儿正立着一位手里拿着一盏灯笼的中年男人。另外，在部分倒装的句子中，只把谓语的一部分（如情态动词、助动

28、词、或是系动词 be）放到主语的前面去，构成倒装语序。例如：Are you going to take part in the football match against Accounting Department on Friday afternoon?（句子的谓语是are going to take part，are是句子的谓语的一部分；句子的主语是you。所以，此句是部分倒装的句子。疑问句都是部分倒装句。）你打算去参加星期五与会计系进行的足球赛吗？Hardly could he finish his test paper when the school bell rang.（由于语法要

29、求的原因，本句写成了部分倒装的句子。它的自然语序应该是：When the bell rang,he could hardly finish his test paper.）他还未做完试卷，下课铃就响了。了解了倒装语序的构成情况后，我们再来看看倒装语序在各种不同类句子中的使用情况：A.在疑问句中各种疑问句一般地说都是倒装语序。例如：Will they come to see us this weekend?这个周末他们将来看我们吗？Are you talking about the film you saw last Monday?你们是在谈论你们上周一看的那部电影吗？Can you speak

30、 another foreign language except English?除开英语，你还能说另一种外语吗？Where did you buy the dictionary,in the book store nearby or in Xinhua bookstore?你在哪儿买的这本词典，是在附近的书店还是在新华书店？She is not a student,isnt she?她不是个学生，对吗？B.在感叹句中某些感叹句也用倒装语序。例如：Isnt it a beautiful garden!多么美丽的花园啊！What a beautiful garden it is!多么美丽的花园啊

31、！（在这种句式中，主语在谓语之前，属于自然语序。对于主语和谓语而言，语序没有倒装。）Have you ever seen such a naughty kid like him!你见过那个孩子像他这么调皮！C.在陈述句中 陈述句在一般情况下用自然语序；但由于英语语法的某些原因，陈述句也要使用倒装语序。这些原因大致可以归纳)为了避免句子部分内容不必要的重复，常用so+be动词（助动词、情态动词）+主语或neither/nor+be动词（助动词、情态动词）+主语的倒装句式。其中第一个句式表示与前面所述的肯定情况相同，第二个句式表示与前面所述的否定情况相同。例如：His brother is a c

32、ollege student;so is mine.他弟弟是大学生，我弟弟也是。His brother is not a college student;nor is min.他弟弟不是大学生，我弟弟也不是。He used to have his further study abroad;so did I.他曾去国外深造过，我也去过。He didnt use to have his further study abroad;neither did I.他没去国外深造过，我也没有。One of my friends can speak three foreign languages;so can

33、 his wife.我的一个朋友会说三门外国语，他的妻子也会。One of my friends cannot speak three foreign languages;neither can his wife.我的一个朋友不会说三门外国语，他的妻子也不会。They are now preparing for their final examinations;so are we.他们正在为期末考试作准备，我们也一样。They are not now preparing for their final examinations;nor are we.他们没在为期末考试作准备，我们也没有。2）具

34、有否定意义的词或短语置于句首时（除否定词修饰主语外），句子一般要写成部分倒装句。这类词或短语常见的有：not,never,seldom,hardly,rarely,scarcely,by no means,under no circumstances,in no way,at no time,no sooner (than),hardly (when),not only (but also),not until,等。例如：Hardly had she sat down when she heard someone knocking at the door.她还没来得及坐下来，就听见有人敲门。N

35、ot until twelve oclock did he go to bed last night.他昨晚直到十二点钟才睡觉。Never have my sisters been to Hong Kong before.我的妹妹们以前从未去过香港。No sooner had I returned home from New Zealand than I bought a house and went to live there.我从新西兰一回国，就买了一栋房子并在那儿住下了。So far as I know,seldom does Mary come back to see her moth

36、er.就我所知，玛利几乎很难回来看她妈妈。Scarcely a drop of rain fell here last fall.（否定词修饰主语时，句子不用倒装。）去年秋天，这儿几乎没下一滴雨。英语中否定句的用法1)一般否定句I dont know this.No news is good news.There is no person/not a person/not any person in the house.2)特指否定He went to his office,not to see him.I am sorry for not coming on time.I dont thin

37、k/believe/suppose/feel/imagine you are right.3)部分否定I dont know all of them.I cant see everybody/everything.All the answers are not right.（并非所有答案都对。）All is not gold that glitters.（闪光的不一定都是金子。）Both of them are not right.（并非两人都对。）4)全体否定None of my friends smoke.I can see nothing/nobody.Nothing can be so

38、 simple as this.Neither of them is right.5)延续否定 You didnt see him,neither/nor did I.You dont know,I dont know either.He doesnt know English,let alone/to say nothing of/not to speak of French.6)半否定句 We seldom/hardly/scarcely/barely hear such fine singing.I know little English.I saw few people.7)双重否定

39、You cant make something out of nothing.Whats done cannot be undone.There is no sweet without sweat.No gain without pains.I cant help/keep/laughing whenever I hear it.No man is so old but(that)he can learn.8)排除否定 Everyone is ready except you.He did nothing but play.But for your help,I couldnt do it.9

40、)加强否定 I wont do it at all.I cant see it any more.He is no longer a boy Only在句首要倒装的情况 Only in this way,can you learn English well.Only after being asked three times did he come to the meeting.如果句子为主从复合句，则主句倒装，从句不倒装 Only when he is seriously ill,does he ever stay in bed.动词的几种语态 语态是动词的一种形式，它用来表示句中主语同谓语

41、动词之间的关系。英语有两种语态，主动语态和被动语态，主动语态表示主语是谓语动词动作的执行者，被动语态表示主语是谓语动词动作的承受者。例如：I have repaired the radio.我修好了收音机。The radio has been repaired.收音机被修好了。The students cleaned the classroom.学生们打扫了教室。The classroom was cleaned by the students.教室被学生们打扫了。被动语态的构成：be+过去分词A building was damaged by the storm.暴风雨毁坏了一座建筑物。Ou

42、r plate was made in China.我们的盘子是中国生产的。My bike was stolen.我的自行车被盗了。常用的被动语态的时态变化如下，以 ask 为例：一般进行完成现在I am asked,I am being asked,I have been asked过去I was asked,I was being asked,I had been asked将来I shall be asked,I shall have been asked 过去将来I shall be asked被动语态的疑问句是把助动词提前到句首。Has your TV set been repair

43、ed?你的电视机修了吗？Was the kite broken?风筝破了吗？Has the work been done?工作结束了吗？被动语态的否定式是在助动词后面加 not.The letter has not been sent out.信还没有发出去。The little boy has not been found out.小孩还没有找到。The cap has not been mended yet.帽子还没有补好。Their money has not been sent to them.他们的钱还没有送到他们手中。谢谢观赏WPS OfficeMake Presentation much more funWPS官方微博kingsoftwps
