1、2023中考英语语法详解很全很实用情态动词、系动词一、情态动词情态动词本身有一定的意义,但不能独立作谓语,要和动词原形一起构成谓语,表说话人的语气和态度。它没有人称和数的变化。常见的情态动词有:1.can表示能力,有“能”“会”的意思;表示可能性,多用在否定或疑问句中;表示请求和许可。如:The parrot can speak three languages.这只鹦鹉能讲三种语言。Can I borrow the book from the library?我可以从图书棺借这本书吗?Shanghai can be very cold in M arch.上海三月份可能会很冷。拓展延伸can还
2、有过去式could可表 能,会,又可以和be ableto替换,而be able to有 更多时态。如:He could swim when he was four.=He was able to swim whenhe was four.他四岁时就会游泳。在一般疑问句中,can/could常用来表示请求或征求对方意见,用could比用can语气更加委婉和客气。类似用法的还有Will/Would you(please)等句型。如:Could you tell me how I can get to the post office?你能告诉我怎样到邮局吗?Would you please tur
3、n up the radio?请你把收音机开大点,好吗?2.may表示 许可 时,相当于can,其否定回答用can t/mustnt;表推测时,常用在肯定句中,表“可能”。如:-M ay I borrow your ruler?我可以借用您的直尺吗?-No,you cant/mustnt.不行。She may be a teacher.她可能是一名教师。拓展延伸may可表示祝愿。如:M ay you succeed!祝你成功!3.must表示“必须;必要”,以“must”开头的一般疑问句其肯定回答用“must”,否定回答用“neednt或 dont have t。”。must表推测时,常用在肯
4、定句中,是“一定”的意思,其否定形式mustn t 表 禁止 的意思。如:-M ust I leave now?现在我必须离开吗?-No,you neednt/you dont have to.没有必要。This book must be Lucys.Look!Her name is on the bookcover.这本书是露西的。看!封面上还有她的名字。You mustnt draw on the wall.你不准在墙上画画。拓展延伸must表示说话人的主观看法,只有一般现在时;have to强调客观要求,有时态、人称和数的变化。如:M y mother is ill.I have to
5、look after her now.妈妈病了,我得去照看她。4.n e e d作情态动词时,常用在否定和疑问句中,表示“需要;要”的意思。如:N e e d w e f i n i s h t h e w o r k n o w?现在我们需要完成这项工作吗?T h e y n e e dn t l o o k a f t e r h i m.他们不需要照顾他了。拓展延伸n e e d还可以用作行为动词,可以用于各种句型。如:D o e s h e n e e d a n y h e l p?他需要帮助吗?T h e de s k n e e ds r e p a i r i n g.这张桌子
6、需要修理。5.s h a l l 用于第一人称,表示说话人征求对方意见,过去式为s h o u l d;w i l l 用手第二人称的疑问句中,表示说话人向对方提出请求和建议,过去式为w o u l d。如:S h a l l I g o s h o p p i n g w i t h y o u?我可以同你去购物吗?I do n t k n o w w h a t I s h o u l d do n e x t.我不知道下一步该干什么。W o u l d y o u p l e a se c o m e a l i t t l e e a rl i e r?请你来早一点好吗?6.情态动词h
7、 a d b e t t e r的.用法(l)h a d b e t t e r后接动词原形,表劝告、建议,意为“最好”。“Yo u d b e t t e r”含有强制命令的语气,对长辈不宜使用。如:Yo u d b e t t e r a sk t h a t p o l i c e m a n o v e r t h e re.你最好问一下那边的那个警察。慎用h a d b e t t e r!注意以下四条:h a d b e t t e r表达的是说话者强硬性的建议,告诫别人(包括自己)如何做。如:G ra n n y,t h e h o sp i t a l i s n o t v
8、e ry n e a r.W e db e t t e r c a t c h a b u s.奶奶,医院不是很近。我们最好坐公共汽车。h a d b e t t e r不用于礼貌的请求或征询,它隐含一种警告或威胁。如:Yo u 1 d b e t t e r f i n i sh t h e w o rk t o d a y a n d b ri n g i tt o m o rro w.你最好今天就把作业完成,明天带来。h a d b e t t e r意思接近sh o u l d,但它除了表示语气强硬以外,还表示马上要去做的事情,比sh o u l d 更紧迫。如:Yo u*d b e
9、t t e r se ea d o c t o r a t o n c e.你最好马上去看医生。h a d b e t t e r不含比较的意思,该结构表示“I t w o u l d b e g o o dt o ”,而不是 I t w o u l d b e b e t t e r t o”。二、系动词系动词有实际意义,但不能单独做谓语,必须与表语一起构成句子的谓语,说明主语的性质、状态或身份等。它分为完全系动词和不完全系动词。1.完全系动词(b e)可接名词、代词、形容词、副词、介词短语、非谓语动词短语、句子做表语。如:I m a st u d e n t.我是个学生。(名词)H e i
10、 s f i n e.他很好。(形容词)I t i s m e.是我。(代词)A rey o u t h e re?你在那儿吗?(副词)S h e i s a t sc h o o l.她在学校读书。(介词短语)H e i s t o c o m e so o n.他过会儿该来了。(不定式)My j o bi s t e a c h i n g E n g l i sh.我的工作是教英语。(动词的i n g 形式)Myidea is that we will start now.我的想法是我们现在就开始。(句子)2.不完全系动词(get,turn,feel,smell,look,sound,t
11、aste)一般只接形容词做表语。如:When spring comes,it gets warmerand warmer.春天来了,天气变得越来越暖和了。Food may go bad soon ifit is not put into a fridge.食物如果不放进冰箱里就会很快变坏。M y brother became/turned a teacher after his graduation.我哥哥毕业后就当上了老师。(注意become和 turn的用法区别)动词的分类一、动词概述及分类根据其句法功能,动词可以分为四大类,列表如下。+宾语,构成主谓宾句型1、实义动词 及物动词+双宾语,
12、构成主谓双宾句型(行为动词)+复合宾语,构成主位复宾句型不及物动词2、连系动词 be,seem,look,sound,smell,turn,get,become 等+彻 表语,构成主系表句型be+doing,构成进行时+done,构成被动语态have+done,构成完成时态+b e e n d o in g,构成完成进行时态3、助动词 肯定式d o (d o e s,帮助行为动词的一般现在时、一旗 d id);般过去时构成疑问句;帮助行为动词的一般现在时、一否定式:d o n t般过去时构成否定与(d o e s n t,d id n t)w ill,s h a ll,s h o uld,+动
13、词原形构成将来时w o uld4、情态动词 c a n,ma y,mus t,后接动词原形一起构成谓语migh t,c o uld 等二、实义动词及用法实义动词也叫行为动词,是四类动词中唯一能独立作谓语的一类动词。根据其句法功能可以分为及物动词和不及物动词两类。1、及物动词及物动词本身意义不够完整,需要后接宾语才能使其意思完整。1)动词+宾语,构成主谓宾句型。例 如:C o uld y o u p le a s e c le a n th e b la c kb o a rd?请你擦黑板好吗?W e le a rn E n glis h e ve ry d a y.我们每天学习英语。2)动词+
14、直接宾语+to/fo r+间接宾语/动词+间接宾语+直接宾语,构成主谓双宾句型。有的动词必须在后面带表示人的间接宾语和表示物的直接宾语,即两个宾语才能表达完整的意思。例如:Who teaches you English?谁教你们英语?Please pass me the book.=Please pass the book to me.请把那本书递给我。M y mother bought me a snow globe on my birthday.=M y mother bought a snow globe for me on my birthday.我过生日时我妈买给我一个雪球。常见的带
15、双宾语的动词有:pass,give,bring,buy,get,leave,lend,make,cook,teach,tell,write,read,return,ask,show等。3)动词+宾语+宾语补足语,构成主谓复宾句型。有的动词必须在宾语后再加上形容词、副词、名词、不定式、-ing形式、介词短语等做宾语补足语,构成复合宾语,句子意思才能够表达完整。例如:Please keep the door open.请让门开着。(形容词open做宾补)I often see the children play in the parko 我经常看见孩子们在公园里玩。(不带to的不定式play做宾补
16、).You can call me M rs Jones.你们可以称呼我琼斯夫人。(名词M rs Jones做宾补)动词 see,hear,watch,make,let,have,notice,find 等经常以动词不定式或-ing形式做宾补。2、不及物动词1)不及物动词自身意思完整,无需再接宾语。例 如:Horses run fasto马儿跑得快。He sings well.他唱得好。2)很多不及物动词也可以用作及物动词,还有的不及物动词后带上某个介词就成了带宾语的及物动词。例如:They are reading.他们在朗读。(read为不及物动词)They are reading Engl
17、ish.他们在朗读英语。(read为及物动词)He is waiting at the bus stop.他在公交车站等。(wait 为不及物动词)He is waiting for me at the bus stop.他在公交车站等我。(wait for为及物动词,带me做宾语)三、连系动词连系动词本身有词义,但不能单独作谓语,必须和其后面的表语一起构成合成谓语,说明主语的 性质、特征、状态或身份。常见的连系动词有be,become(变得、成为),get(变得),look(看起来),seem(似乎、好像),turn(变得),sound(听起来),smell(闻起来),taste(尝起来),
18、feel(摸起来)等。除b e以外的连系动词大多数时候是实义动词,他们用作连系动词时多数没有进行时态,也没有被动语态。例如:He is angry.他生气了。He got angry at the news.听到这个消息他生气了。That sounds good.那听起来不错。Trees turn green when spring comes.春天来临,树叶转绿。China is getting stronger and stronger.中国正变得越来越强大。四、助动词助动词本身没有词义或意思不完整,不能单独作谓语。它们的主要作用是帮助构成时态、语态、疑问句或否定句等。1、助动词 be(a
19、m,is,are,was,were)1)be+doing(现在分词),构成进行时例 如:They are listening to music.他们在听音乐。(be的现在时形式帮助构成现在进行时)They were walking down the street when the U FO landed,(be的过去时形式帮助构成过去进行时)2)be+done(及物动词的过去分词),构成被动语态例如:The light bulb was invented by Thomas Edison.电灯泡是由托马斯.爱迪生发明的。(be的过去时形式帮助构成过去时的被动语态)The classroom i
20、s cleaned every day.教室每天打扫。(be 的现在时形式帮助构成现在时的被动语态)The problem will be solved next week.这个问题将在下周得到解决。(be的将来时形式帮助构成将来时的被动语态)2、have(has,had)l)have/has/had+done(动词的过去分词),构成完成时态。例如:They have already done their homework.他们已经完成作业。(have+过去分词构成现在完成时)He hasn,t come yet.他还没有回来。(has+过去分词构成现在完成时)The bus had gone
21、 when I got to the bus stop.我到达车站时公交车已经离开。(had+过去分词构成过去完成时)2)have/has/had+been+doing(动词的现在分词),构成完成进行时态。例如:How long have you been collecting shells?你收集贝壳有多长时间了?He has been studying English since five years ago.他从 5年前开始就一直在学习英语。3、助动词 do/does/did助动词do/does/did主要帮助构成疑问句,也可用于倒装句、强调句或代替上文提到过的行为等。他们的否定式don

39、going to be a class meeting tomorrow.明天将有一个班会。They visited the aquarium yesterday,他们昨天参观了水族馆。2)频度副词:如 sometimes,often,always,usually 等,在句子中担任时间状语,是决定动词时态的主要依据之一。例如:They have never seen each other before.他们以前从未见过面。What do you usually do on weekends?你们周末通常做什么?3)地点副词:如 here,there,home,somewhere,anywher

43、从不迟到。He u s u a l l y g o e s t o s e e h i s g r a n d p a r e n t s o n S a t u r d a y.他通常周六去看望爷爷奶奶。2)e n o u g h修饰形容词或副词时要放在被修饰词的后面。例如:T h e l i t t l e b o y i s n,t o l d e n o u g h t o g o t o s c h o o l.小男孩没到上学的年龄。He r a n f a s t e n o u g h t o c a t c h t h e t h i e f.他跑得够快,抓住了小偷。三、形容词
