1、英语助动词有shall, will, should, would, be, have, do等。The students are playing football now. (构成现在进行时) He does not like playing football. (构成否定句) Do you like playing football? (构成一般疑问句) Do come here tomorrow! (构成强调句 )典型错句解析1. You must look after yourself and keep health.解析 healthhealthy. keep作系动词用时,后接形容词。
2、2. He will become a pianist.解析will becomebecame become作系动词用时,一般不用于“将来成为”的意思。此句又可改为 He has become a pianist.3. You will twenty-five years old next month.解析 willwill be。助动词will本身没有词义,可用在各种人称的将来时态中。 Will在将来时态中后接动词原形。 will + be才能构成完整的谓语。4.He works even harder than you work.解析 workdo。助动词do代替主要动词,以避免重复。二代
3、词 代词是用来代替名词或名词词组的词,因此代词在句子中的功能和名词一样,可作主语、宾语和表语,有些代词还可修饰名词。 英语代词可分为人称代词、物主代词、指示代词、反身代词、疑问代词、关系代词、连接代词、不定代词、相互代词等九种。现把学过的六种代词介绍如下:代 词单 数复 数第一人称第二人称第三人称人称代词主格Iyouhe, she, itwethey宾格mehim, her, itusthem物主代词形容词性myyourhis, her, itsourtheir名词性mineyourshis, hers, itsourstheirs反 身 代 词myselfyourselfhimself, h
4、erself, itselfourselvesyourselves themselves指 示 代 词this, thatthese, those不定代词可数 each, one, many, (a)few, both, another, either, neither不可数 much, (a) little可数、不可数 all, some, none, such, any, other复合不定代词 anybody(one, thing), somebody(one, thing), nobody(thing), everybody(one, thing)疑 问 代 词 who, whom,
5、whose, which, what 1人称代词 表示“我”、“你”、“他”、“她”“它”“我们”、“你们”、“他们”等的词,叫做人称代词。人称代词的排列有以下几种; 我、你、他 第二人称第三人称第一人称 即:you,he and I 她和老师 名词人称代词 即:the teacher and she 我、他和一些别的人 人称代词其他代词 即: he,I and some others 第三人称两性(性别)并用时,如:他和她;即:he and she 人称代词的主格作主语,宾格作及物动词宾语或介词宾语。作表语时,书面语用主格,口语中则用宾格。You must speak English as
6、often as possible He told me the bad news He didnt listen to me Whos going to go? (以上代词在句中分别作什么成份?)2物主代词 物主代词表示所有关系,分为形容词性和名词性两种,形容词性物主代词作定语,名词性物主代词作主语、宾语和表语。形容词性物主代词后要跟名词。名词性物主代词可以单独使用,其作用相当于一个形容词加上一个名词。物主代词有人称和数的区别。例:This is my dictionaryYours (=Your dictionary)is on the desk 一Is this your classro
7、om? NoIts theirs(=their classroom)3反身代词 表示动词所表达的动作反回到施动者本身,一般是由第一、二人称的形容词性物主代词或第三人称代词的宾格加上self (复数selves) 构成,起强调作用,反身代词可作动词宾语、介词宾语、同位语等。Please help yourself to some fish(作动词宾语) He thinks more of himself than“others(作介词宾语) I myself did it(作同位语) I spoke to the manager himself(作同位语)注:反身代词常接在动词enjoy, hu
8、rt, help等词后。4指示代词 指示代词是将所指事物与同类中的其他事物区分开来的一种代词。表示:“这个”、“那个”、“这些”、“那些”等指示概念。指示代词在句中相当于名词、形容词的作用,可作主语、宾语、定语、表语等。This(That) is what I want to say(作主语) We should always keep this(these) in mind(作宾语) For these(those) reasons,I was late(作定语) The reason is this(作表语)5不定代词 不定代词用来代替或修饰任何不定数量和不定范围的人和事物。不定代词可代替
9、名词或形容词,在句中作主语、宾语、表语和定语。下面举例说明: some和any some(一些)、any(一些、任何)修饰可数名词和不可数名词。some用在肯定句中,any多用于疑问句和否定句中。There are some books in the desk There are not any books in the desk Have you any money?注意:some可用于表示邀请、请求的疑问句或用于说话者希望得到肯定回答的疑问句中,any有时也用于肯定句,表示“任何的”“任何一个”“任何一些”等。Would you like some tea? (希望对方肯定回答) Yes,
10、 thank you. Could I ask you some questions? Of course, you can. You can ask me any questions.(任何问题) little、a little、few、a few little、a little修饰不可数名词,few、a few修旆可数名词;a little、a few表示肯定的概念,即:尽管少但“有”;few、little表示否定的概念,表示“没有”。There is a little water in the river.

I have a few friends in AmericaI often write to them. each、every、everybody、everyone、everything。 each相当于名词和形容词,用作定语或单独使用作主语、宾语、定语、同位语等。every不可单独使用,它必须放在名词等前,只能作定语。each与every的区别: 1)each侧重于单个,every侧重于全体 、整体。 2
12、)each用于二者或二者以上,every用于三者或三者以上。everybody与everyone相同,意思是“每人、人人”。everything意思是“一切”“每件事”。Two boys came into the classroomEach wore a red coat. Every student has a new book Everybody knows this thing(dont they? Everything goes well(doesnt it? (把上面两个句子改为反意疑问句,注意用什么代词代替everybody, everything) both、either、ne
13、ither both、either、neither都与“两个”有关。 both “(两者)都-”全”,指两个人或事物,可作主语、宾语、定语。 例如:Both books are good There are a lot of trees on both sides of the road. either (两个中间的)任何一个,这个或那个”,可作主、宾、定语。There are two books. You may take either of them Would you like a cup of tea or coffee? Either is OK. neither “(两者之间) 一
14、个也不-”,neither是either的否定形式,可作主语、宾语、定语。 例如:Neither of them knows Japanese Either Li or Wang knows English none、no、nobody、no one、nothing none、no、nobody、no one、nothing都与“无”有关。 none用于指人或物,可与of短语连用,用作单数或复数,而且常用于习语中。 nothing“没有东西;没有什么 (=not anything)”,若作主语,谓语动词用单数形式。Is there nothing in the box? No. Its emp
15、ty 一How many elephants did you see there? None What did you see in the zoo yesterday? Nothing.以上两句中的答句None, Nothing不可相互替代。 no表示“没有(任何的)-”,等于not any- 或 not a(an)-。 He has no money(= He has not any money.) We have no lessons on Sundays. (= We have not any lessons on Sundays.) She has no brother. (= Sh
16、e has not a brother.) nobody或no one后不可接of短语来表示“某些人当中”;a11 a11作形容词且与名词连用时,名词前需加the或ones,即:all the(ones) + 名词。I will teach English all my life All the people are here 当all代替可数名词作句子主语时,谓语动词用复数;当all代替不可数名词作句子主语时,谓语动词用单数。All are hereLets begin our meeting. (all代替所有参加会议的人) All is well that ends well.(all代
