  知识点总结

  在英语中,句子中的谓语动词在人称和单、复数形式上必须和主语保持一致,这就是我们通常说的“主谓一致”。这一点看似简单,但在实际运用中却常常遇到麻烦。一般情况下,主谓之间的一致关系由以下三个原则的支配: 语法一致原则、 意义一致原则和就近原则。

  一、语法一致

  主谓一致的原则是指主语和谓语从语法形式上取得一致:主语是单数形式,谓语也采取单数形式;主语是复数形式,谓语亦采取复数形式.例如:

  He often helps me learn English. (主语是单数形式,谓语也采取单数形式) .

  My friends often help me learn English. (主语是复数形式,谓语也采取复数形式)

  但主语和谓语从语法形式上取得一致的问题远不只上述的那么简单,有许多方面的情况需要去具体地对待:

  1、不定式,动名词,以及从句作主语时应看作单数,谓语动词用单数.

  例如: Reading aloud is helpful to learn English.大声朗读对学习英语是有帮助的。

  What he said has been recorded .他说的话已被录音了.

  2、不定代词one, every, each, everybody, everyone, one of, no one, nothing, nobody, someone, somebody, either, neither, many a 等作主语或是修饰主语时应看作单数,谓语动词用单数.但none 作主语时,谓语动词既可用单数也可用复数,这要取决于说话人的看法。

  例如:Neither of my sisters likes sports .我的妹妹中没人喜欢运动.

  Every boy and girl shows great interest in this book .每个男孩和女孩对这本书都表现出很大的兴趣.

  3、表示国家,机构,事件,作品等名称的专有名词作主语时应看作单数,谓语动词用单数.

  例如: One Thousand And One Nights tells people lots of interesting stories . 《一千零一夜》给人们讲了许多有趣的故事。

  4、 a kind of, the number of等与名词构成名词短语作主语时应看作单数,谓语动词用单数.

  例如: The number of workers in the factory is 400. 这个工厂里工人的数量是400.

  A kind of rose in the garden smells very pleasant.这座花园里有一种玫瑰香气怡人.

  5、由some, several, both, few, many, a number of 等词修饰主语,或是由它们自身作主语时应看作复数,谓语动词用复数.另外,由and连接两个主语时,谓语一般用复数.

  例如: On the seashore, some people are playing volleyball 海边,有些人在打排球。

  Both of us are fond of watching football games .我们俩都喜欢看足球赛.

  A number of will-be graduates are voluntarily going to work in the West of China. 许多即将毕业的学生打算自愿去中国西部工作.

  6、有些表示数量的百分数,分数等后面加名词或代词作主语时,要根据这个名词或代词来决定其谓语动词的单复数形式.如:a lot of, most of, any of, half of , three fifths of, eighty percent of, some of, none of, the rest of , all of等后接不可数名词,或是单数形式的名词作主语时应看作单数,谓语动词用单数;但如果后接可数名词的复数形式作主语时应看作复数,谓语动词用复数.

  例如: A lot of money in the shop was stolen yesterday. 昨天那家商店丢失了许多钱.

  A lot of students are from England in the school.那个学校里很多学生来自英国。

  二、意义一致

  这一原则是指,从意义着眼来解决主谓一致问题.有时主语形式上为单数,但意义上却是复数,那么谓语依意义也用复数形式;而有时主语形式上为复数,但意义上却是单数,那么谓语依意义亦用单数形式.

  1) 当主语后面接由but, except, besides ,as well as, as much as, including,more than,no less than, rather than, together with等引导的词组时,其谓语动词的单复数形式通常由前面的词来决定。在这样的句子里,这些词所引导的词组不影响主语自身的单,复数形式,它们在句子里其实是状语.

  例如: The teacher, with all his students, is going to have a picnic this weekend.老师打算这个周末与学生们一起去野炊.

  The students, together with their teacher , are going to have a picnic this weekend.学生们打算这个周末与他们的老师一起去野炊.

  我们完全可以将上面句子中的那些词组都分别搬到句首或是放到句末去,因为它们在句子里是状语: The students are going to have a picnic this weekend together with their teacher.

  2) 表示时间,金钱,距离,体积,重量,面积,数字等词语作主语时,,谓语动词常用单数形式。如:

  Eight hours of sleep is enough. 八小时的睡眠足够了。

  Twenty years stands for a long period in one's life. 二十年在人的一生里意味着一个很长的时期.

  3) 形容词前加定冠词即"the + 形容词"作主语时,其意义若是指个人或是抽象概念应看作单数,谓语动词用单数;指一类人则应该看作是复数,那么谓语动词也应该用复数.

  例如: The sick here are very well cared for. 这里的病人都被照顾得很好。

  The true is to be distinguished from the false. 真实与虚假应加以区别。

  4)由and 连接的两个单数名词作主语时,谓语动词一般根据语法一致的原则用复数。

  但如果在意义上指同一个人、同一件事或同一个概念时,谓语动词要用单数形式。

  如:The writer and teacher is coming. 那位作家兼教师来了。(作家和教师指同一个人)

  The writer and the teacher are coming. 作家和老师来了。(作家和老师是两个人)

  5)集体名词作主语时,谓语动词的数取决于主语的意义:主语表示整体时视为单数,谓语动词用单数;主语表示集体中的个体成员时视为复数,谓语动词用复数.这类集体名词常见的有:army, class, club, crowd, family, government, group, people, police, public, team等.

  例如: The family are all fond of football. 那一家人都喜欢足球.

  The family is the tiniest cell of the society. 家庭是社会的最小的细胞.

  6)一些形式为复数,意思为单数的名词,如:trousers, pants, shorts,glasses, 等作主语时,谓语动词用复数.

  如:Her glasses are new. 她的眼镜是新的.

  但当这类名词前有a pair of 修饰时,谓语动词应用单数.

  如: This pair of trousers is made in Hangzhou.

  三、就近原则

  这一原则是指,谓语动词的人称和数常常与最近作主语的词语保持一致.常出现在这类句子中的连词有:or, either… or …, neither… nor … ,not only… but also …等.

  例如: Either I or they are responsible for the result of the matter. 不是我,就是他们要对那件事的结局负责任.

  Neither his family nor he knows anything about it. 他全家人和他都不知道那件事.

  常见考法

  对于主谓一致的考查,通常会以单选的形式出现,多是让我们选择合适的谓语动词。

  典型例题:The factory, including its machines and buildings, __________ burnt last night.

  A. is B. are C. were D. was

  解析:but, except, besides, with, together with, along with, including, as well as, rather than, like等词连接主语时,谓语动词和前面的主语保持一致,本题中就是和The factory保持一致。而这些词所引导的词组不影响主语自身的单,复数形式,它们在句子里其实是状语.

  答案:D

  误区提醒

  主谓一致这一知识点比较琐碎,在运用中常会因为考虑不全面而出错,所以我们必须把每一种用法记住,灵活运用。尤其要注意就近原则、集体名词和百分数,分数短语作主语的情况。

  典型例题:Either Jane or Steven _____ watching TV now.

  A. were B. is C. was D. are

  解析:本题考查的是就近原则。either… or …, neither… nor … ,not only… but also …连接两个主语时,谓语动词的人称和数常常与最近作主语的词语保持一致。本题中就是和Steven保持一致。有now.可知是现在进行时,排除A和C.

  答案:B

初中英语知识点总结2

  一、陈述句:

  陈述句是用来陈述一个事实或表达说话人看法(包括肯定和否定)的句子。通常用降调,句末用句号“.”。

  Tom has a new car.汤姆有辆新车。

  The flower isn’t beautiful.这花不美。

  二、陈述句否定式的构成

  1.如果肯定陈述句的谓语部分含有助动词、情态动词或连系动词be,则只需在这些动词后加not即可构成否定式。

  He is playing the guitar.他正在弹吉他。(肯定)

  He is not playing the guitar.他不在弹吉他。(否定)

  We can get there before dark.天黑前我们能够到达那里。(肯定)

  We can’t get thee before dark.天黑前我们不能到达那里。(否定)

  2.如果陈述句的谓语动词是实义动词,而其中又没有情态动词或助动词时,则需根据人称和时态在该实义动词前加don’t,doesn’t或didn’t。同时把该实义动词变为原形。

  He plays the violin well.他小提琴拉的很好。(肯定)

  He doesn’t play the violin well.他小提琴拉的不好。(否定)

  She won the game.她赢得了比赛。588.es(肯定)

  She didn’t win the game.她没赢比赛。(否定)

  三、祈使句:

  祈使句是用来表示命令、请求、建议、号召等的句子,谓语动词用原形,句末用感叹号“!”或句号“.”。朗读时一般用降调。

  1.肯定的祈使句:

  (1)祈使句主语是you时,you常省略,但如果要特别强调对方或表达某种强烈的情绪时可以有主语或称呼语。

  Be quiet.请安静。

  You be quiet!你给我安静点!

  (2)“Do+祈使句”表示一种强烈的感情或请求,do起强调作用。

  Do come back at once!务必立即返回!

  Do be careful.务必小心。

  (3)please用在祈使句中可以表示一种客气的语气,但please用在句末时,必须用逗号与其余部分分开。

  Open the window,please.请打开窗户。

  (4)Let引导祈使句时,后面需跟上人称代词或称呼语,人称代词一般只用第一、第三人称。

  Let Jack wait a minute.让杰克等一会。

  Let’s go to school.我们上学去吧。

  (5)在祈使句中,Let’s和Let us是有区别的。Let’s包括说话者,而Let us不包括说话者在内。这点从反意疑问句时可明显看出。

  Let’s go skating,shall we?咱们去溜冰吧,好吗?(表示内部的建议)

  Let us try again,will you?让我们再试一次,好吗?(表示向别人发出请求)

  一、一般疑问句:

  (1)一般疑问句的肯定形式

  一般疑问句一般是指以助动词、情态动词、be动词或have(有)开始,通常要求以yes,或no来回答的疑问句,一般疑问句读时通常用升调。

  Do you know Mr.Smith?你认识史密斯先生吗?

  Can you swim?你会游泳吗?

  (2)一般疑问句的否定结构

  ①在一般疑问句的否定结构中,把副词not放在一般疑问句的主语之后。但如果用not的简略形式-n’t,则须将-n’t与一般疑问句句首的be,have,助动词或情态动词写在一起。在实际运用中,一般都采用简略式。

  ②与汉语不同的是,英语一般疑问句否定结构的答语是否定还是肯定,全由答语的否定或肯定来决定。若答语是肯定的,则用yes加肯定结构;若答语是否定的,则用no加否定结构。

  Aren’t you a football fan?你不是足球迷吗?

  Yes,I am.是的,我是。

  No,I am not.不,我不是。

  Won’t she like it?她会不喜欢吗?

  Yes,she will.是的,她会(喜欢)的。

  No,she won’t.不,她不会(喜欢)的。

  二、特殊疑问句

  用疑问代词疑问形容词或疑问副词引导的疑问句叫特殊疑问句。特殊疑问句不能用yes或no回答,读时用降调。588.es

  常见的疑问代词有what,which,who,whom,whose

  常见的疑问形容词有what,which,whose

  常见的疑问副词有when,where,why,how

  三,选择疑问句:

  选择疑问句是说话者提出两种或两种以上的不同情况,让对方选择回答的疑问句。其结构是“疑问句+选择部分”。选择部分由or连接,or前面的部分读升调,or后面的部分读降调。

  选择疑问句不能用yes或no回答,而必须具体的选择答复。

  Is your bag yellow or black?It’s black.。

  Would you like some tea or coffee?Either will do.。

  Which do you like better,singing or dancing?I like dancing better.

  四,反意疑问句:

  反意疑问句是指在陈述句之后附加一个意思与之相反的简短问句,问对方是否赞同的疑问句。附加问句的否定式必须缩写。

  (1)肯定的陈述句后跟否定的附加问句,否定的陈述句后跟肯定的附加问句。

  I am your teacher,aren’t I?我是你的老师,对吗?

  He didn’t study hard,did he?他学习不努力,对吗?

  (2)如果陈述句中含有否定副词never(从不,决不),hardly(几乎不)或其他表示否定代词或形容词,如nothing,none no one,nobody,neither,few,little等,则附加问句只能用肯定式。如:

  They hardly write to each other,do they?他们几乎不给对方写信,是吗?

  He has found nothing,has he?他什么也没有找到,是吗?

  Few people knew the secret,did they?很少有人知道这个秘密,是吗?

  (3)当反意疑问句是“否定陈述句+肯定附加问句”时,英语与汉语的回答习惯存在差异。英语回答时只看实际情况,若答语的具体内容是肯定的就用“Yes+肯定结构”,答语的具体内容是否定的就用“No+否定结构”,而译成汉语时,则必须把yes译“不是”,把no译成“是的”。

  You won’t be away for long,will you?你不会离开太久,是吗?

  Yes,I will.不,我会离开很久。No,I won’t.是的,我不会离开很久。

  I don’t think she’ll come by bike,will she?我认为她不会骑自行车,会吗?

  Yes,she will.不,她会骑自行车来。No,she won’t.是的,她不会骑自行车来。

  五,掌握由what,how引导的感叹句的构成形式、用法及区别

  感叹句是表示喜、怒、哀、乐以及惊异等感情的句子。句末用感叹号“!”,读时用降调,感叹句往往由what或how引导,what修饰名词,how修饰形容词,副词或动词。

  1.what引导的感叹句:

  (1)what+a/an+形容词+单数可数名词+陈述句(主语+谓语)

  What a beautiful city it is!多么美丽的一个城市啊!

  What an interesting story she told!她讲了一个多么有趣的故事啊!

  (2)what+形容词+复数可数名词/不可数名词+陈述句(主语+谓语)

  What expensive watches they are!多贵的手表啊!

  What terrible weather it is!多么恶劣的天气啊!

  2.How引导的感叹句:

  (1)How+形容词/副词+陈述句(主语+谓语)

  How cold it is!多冷啊!

  How hard he works!他工作多么努力啊!

  (2)How+陈述句(主语+谓语)

  How he loves his son!他多么爱他的儿子啊!

  How I miss you!我多想你啊!

  (3)How+形容词+a/an+单数可数名词+陈述句(主语+谓语)

  How tall a tree it is!多么高的一棵树啊!

  How they cried!他们哭得多伤心啊!

  (一)掌握时间和条件状语从句中的时态与主句时态的搭配

  (1)时间状语从句:

  引导时间状语从句的从属连词有when(当……时候),while(当,在……过程中),since(自从……以来),before(在……之前),after(在……之后),tell/until(直到……时),as soon as(一……就)。如果主句为一般将来时,则时间状语从句只能用一般现在时表示将来的意义。

  He was reading the newspaper when I came in.当我进来时,他正在读报纸。

  Keep an eye on my cat while I am away.我不在时,请照看一下我的猫。

  Don’t talk so loud while others are studying.别人学习时不要大声说话。

  It has been five years since she went abroad.她出国已有五年了。

  He died before his son came back.他在他儿子回来之前就去世了。

  I’ll show him around our factory as soon as he arrives.他一到达我就领他参观我们的工厂。

  I’ll tell him about it as soon as I see him.我一见到他就告诉他。

  (2)条件状语从句:引导条件状语从句的从属连词是if(如果)。如果主句是一般将来时,条件状语从句只能用一般现在时。

  If you stay at home,I’ll go.如果你呆在家里,我就走。

  If we don’t get up early,we won’t catch the train.如果我们不早起,我们就赶不上火车。

  (二)掌握宾语从句的语序及其时态与主句时态的呼应

  (1)宾语从句的语序:

  宾语从句的语序一律使用陈述语序。尤其是在把两个独立的句子连成一个含有宾语从句的复合句时必须特别注意:

  当宾语从句原为陈述句时,用that引导,语序不变。(注意时态的一致)

  Tom isn’t a good student.The teacher told us…→

  The teacher told us Tom wasn’t a good student.老师告诉我们汤姆不是一个好学生。

  He has given up smoking.She said…→

  She said he had given up smoking.她说他已经戒烟了。

  当宾语从句原为一般疑问句时,用whether或if连接,语序变为陈述语序。

  Is Jim a doctor?I wonder…→

  I wonder whether Jim is a doctor.我想知道吉姆是否是个医生。

  Does she dance well?Can you tell me…→

  Can you tell me if she dances well?你能告诉我她舞跳的是否好吗?

  当宾语从句原为特殊疑问句时,特殊疑问词即为连接词,语序变为陈述语序。

  She asked me where you were going.她问我你去哪里。

  She wondered what he wanted to do.她不知道他想干什么。

  (2)宾语从句的时态:

  宾语从句的时态原则上应与主句的时态保持一致。

  如果主句是现在时态(包括一般现在时,现在进行时和现在完成时),宾语从句可以是实际需要的任何时态。

  I am wondering whether he has come or not.我不知道他是否已经来了。(现在完成时)

  Please tell me when we’ll have the meeting.请告诉我什么时候开会。(一般将来时)

  I don’t know who they are talking about.我不知道他们正在谈论谁。(现在进行时)

  I have heard the window was broken by John.我已经听说窗户是被约翰打破的。

  如果主句是过去的时态(包括一般过去时,过去进行时),宾语从句必须选用过去的某一时态(即一般过去时,过去将来时,过去进行时或过去完成时等)

  He said he would kill her.他说他会杀了她。(过去将来时)

  She told us Lucy had returned home.她告诉我们露茜已经回家去了。(过去完成时)

  Mary was wondering who could answer the question.

  玛丽想知道谁能回答这一问题。(一般过去时)

  I didn’t told them where you were having the meeting.

  我没有告诉他们你们正在哪儿开会。(过去进行时)

  如果宾语从句表示的是科学其理、客观事实或格言警句等,则不管这句是何种时态,从句一律用一般现在时。

  Granny told me that the earth moves around the sun.奶奶告诉我地球围绕太阳转。

  She said a friend in need is a friend indeed.她说患难朋友才是真正的朋友。

  (三)了解定语从句的构成基本形式及基本用法

  (1)定语在句中是用来修饰名词或代词的,一般由形容词或与之相当的其它词类来充当。如果起修饰作用的是一个句子的时候,就叫作定语从句。但定语从句不是象形容词那样放于名词前,而是放在名词之后。它所修饰的名词又被叫作先行词。588.es

  (2)定语从句的引导词有关系代词:that,which,who,whom,whose和关系副词when,where,why,how。

  1.that的先行词可以是人也可以是物。

  A plane is a machine that can fly.飞机是一种会飞的机器。

  I like the book(that)you lent me yesterday.我喜欢你昨天借给我的那本书。

  2.which的先行词只能是物。

  The book shop is a shop which sells book.书店是销售书的商店。

  The book(which)I read last night was wonderful.我昨晚看的那本书很精彩。

  3.who在定语从句中作主语;whom是who的宾格,在定语从句中作宾语;而whose则是形容词性物主代词,在从句中作定语。

  The man who visited our school yesterday is an American friend

  昨天参观我们学校的人是一位美国朋友。

  Who's that woman(whom)you just talked to?

  你刚才与之谈话的那个女人是谁?

  This is our classmate,Mary,whose home is not far from our school.

  这是我们的同学玛丽,她的家离我们学校不远。

  4.关系代词whom,which在定语从句中作介词宾语时,可以和介词一起放于先行词与定语从句之间,有时为了关系紧凑也可以将whom与which与先行词紧挨着书写,而将介词置于定语从句的后面,如:

  That was the room in which we had lived for ten years.那是我们曾经住了十年的房子。

  =That was the room which we had lived in for ten years.

  (3)除关系代词外,还有关系副词when,where,why等也能引导定语从句。

  1.when用来指时间,在定语从句中作时间状语。

  I never forget the day when I first came to the Great Wall

  我永远也不会忘记我第一次到达长城的那天。

  2.where则指地点,在定语从句中作地点状语。

  This is the house where the old man lives.这就是那位老人住的房子。

  3.why用来指原因,作原因状语。

  That’s the reason why he didn’t come yesterday.那就是他昨天为什么没有来的原因。

初中英语知识点总结3

  I.要点

  表示说的话不是事实,或者是不可能发生的情况,而是一种愿望、建议或与事实相反的假设等。一般常用于正式的书面语中。

  1、虚拟语气的构成

  如:与现在事实相反

  If I had more time, I should study German.(fact:I have no more time, so I shall not study German. )

  If she were not so busy, she would attend the meeting this afternoon.(fact:she is very busy, so she will not attend the meeting this afternoon.)

  If they didn’t take physical exercises every day, they wouldn’t be so healthy.(fact: they take physical exercises every day, so they are very healthy.)

  与过去事实相反:

  I would have checked my paper again if I had had more time at yesterday’s examination.(fact:I had no more time at yesterday’s exam, so I didn’t check my paper again)

  You would have already recovered from his illness if he had seen the doctor in good time.(fact: He didn’t see the doctor in good time ,so he hasn’t recovered from his illness )

  与将来事实相反:

  If it rains tomorrow, our picnic will be put off.(The weather has been changeable these days.)

  If it rained tomorrow, our picnic would be put off.( The weather has beenvery good these days.)

  If it should rain tomorrow, our picnic would be put off.(That would be out of our expectation.)

  If it were to rain tomorrow, our picnic would be put off. (条件从句谓语动词用were to +动词原形,表示下雨的可能性极小。Were to rain和should rain都表示“出乎意料之外”,但were to加强表示“当初没想到以后的事”)

  注:

  (1)如果条件从句谓语动词包含有were或had, should, could有时可将if省去,但要倒装。如:

  Had you (If you had) invited us, we would have come to your party.

  (2)混合时间条件句的用法:

  有时条件从句的动作和主句动作发生的时间不一致。这时动词的形式,应根据它所要表达的具体时间来决定用什么形式。

  1) If she hadn’t trained so hard, she wouldn’t be run so fast.(从句叙述过去,主句叙述现在。)

  (fact: she has trained very hard, so she would able to run fast.)

  2)You would speak English well enough if you had practised reading and speaking it every day.(主句叙述现在,从句叙述过去)

  (fact: You didn’t practice (hasn’t practiced ) reading and speaking it every day, so you can’t speak English well enough.)

  (3)在其他状语从句中的用法

  主要用于由as if (as though)引导的比较状语从句,从句中谓语动词一般用“动词的过去式(be变were )或had +过去分词。”如:

  She looked as if she were ill.(实际上她没有病,在这里用虚拟语气补语比喻她精神不佳)

  Xiao Liu speaks English so well as if he had studied in England.(这里用虚拟语气表现他的英语说得好)

  2、虚拟语气在各种从句的应用

  (1)在主语从句中用来表示惊奇、惋惜、理应如此等,其谓语形式是"should(可省) +动词原形",常用于以下三种句型中。

  句型一:It is necessary (important, natural, strange, etc) that…

  句型二:It is a pity (a shame, no wonder, etc) that…

  句型三:It is suggested (requested, proposed, desired, etc) that…

  如:It is strange that he (should) have done that.

  It is a pity that he (should) be so careless.

  It is requested that we (should) be so careless.

  (2)在宾语从句中用于suggest, propose, move, insist, desire, demand, request, order, command等动词后的宾语从句中,表间接的命令和建议。其谓语形式是"(should)+动词原形"。如:

  I suggest that we (should) go swimming.

  (3)在表语从句中,表示间接的命令,要求、请求、建议、决定等,主句中的主语通常是suggestion, proposal, request, orders, idea等。从句谓语形式是"(should)+动词原形"。如:

  His suggestion is that we (should) leave at once.

  (4)在同位语从句中,谓语形式是"(should)+动词原形"。如:

  We received order that the work be done at once.

  (5)在It is time that…句型中,其谓语动词形式是"动词的过去式"或"should +动词原形",should不可省。如:

  It's time (that) we went ( should go) to school.

初中英语知识点总结4

  宾语从句

  1.宾语从句的含义

  在主句中做宾语的从句叫做宾语从句。

  如:She knew that the teacher had seen the film.她知道这位老师看过这部电影。

  “that the teacher had seen the

  film”做knew的宾语,同时又是由连接词that引导的从句,所以它叫做宾语从句。

  2.宾语从句的分类

  (1)动词宾语从句:顾名思义,它是位于动词后面的宾语从句。

  如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。

  (2)介词宾语从句:顾名思义,它是位于介词后面的宾语从句。

  如:I agree with what you said just now.我同意你刚才说的话。

  (3)形容词宾语从句:顾名思义,它是位于形容词后面的宾语从句。

  如:I am afraid that I will be late.恐怕我要迟到了。

  3.引导名词性从句的连接词

  (1)that:没有含义,在宾语从句中不做成分

  (2)whether/if:表示是否,在宾语从句中不做成分。

  I don t know if /whether he still lives here after so many

  years.我不知道这么多年后,他是否还住在这里。

  (3)连接代词:what, which, who, whom, whose(在宾语从句中做主、宾、表和定语)

  连接副词:where, when, how, why(在宾语从句中做状语)

  The small children don t know what is in their

  stockings.(what在宾语从句中做主语)这些小孩子不知道什么在他们的长筒袜里。

  Could you tell me why you were late for the meeting this

  morning?(why在宾语从句中做原因状语)你能告诉我为什么你今天早上开会迟到吗?

  I don t know when he will come back.我不知道他将何时回来。

  He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。

  ②当主句是过去时态时,宾语从句必须是一种过去的时态。

  She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。

  He said that he could finish his work before supper.他说他会在晚饭前完成工作。

  ③当表示客观事实或普遍真理的句子做宾语从句时,任何时候都用一般现在时。

  1、以there或here引起的句子,谓语是be动词时,如果主语是并列的几个名词,谓语动词应和最靠近它的.一个名词保持人称和数的一致。

  例如:

  There are two trees and a well behind the house.

  Here is an apple,two oranges and some peaches for you.

  2、由neither…nor/either…or/not only…but also/not…but等连接的名词或代词作主语时,谓语动词应与最靠近他的一个名词或代词保持人称和数上的一致。

  例如:

  Neither jack nor I have seen the film.

  Either you or I am worry.

  Not only you but also he comes here every day.

  3、each和由some/any/one/every/构成的复合代词,都作单数看待,谓语动词应用单数形式。

  例如:

  Each of us has something to say .

  Is everyboday ready?

  Someboday is using the phone.

  4、主语后接with/together with/as well as/but等短语作定语时,谓语形式不受定语的影响。

  例如:

  The teacher together with his students is going there on foot.

  5、many a(许多)和more than one(不止一个)等作定语去修饰作主语的单数可数名词时,谓语动词用单数。

  例如:

  Many a way has been tried.

  6、pair of等表示数量的名词短语修饰主语时,谓语的形式要与pair等名词形式一致。常见的有:pair of/kind of/type of/box of等。(但a lot of/lots of和a number of不属于这一类)。

  例如:

  There is a pair of shoes left.

  7、从句或短语(包括不定式和动名词)作主语时,往往表达一种抽象概念,谓语动词用单数。

  例如:

  Waving hand is to say“goodbye”.

  What he said is wrong.

  8、maths/news/physics/the united states等单数概念,复数形式的名词作主语时,谓语动词多用单数。

  例如:

  Twenty years is a long time.

  2、副词比较级的变化规则基本与形容词比较级相同 (不规则变化:well-better, far-farther)

初中英语知识点总结11

  知识点总结

  一、 形容词是用来描写或修饰名词或代词,说明人或事物的特征或性质的, 形容词往往被译成“···的”。用法如下:

  1.做定语。e.g. This is an old house.

  2.做表语。e.g.I am sorry to hear that.

  3.做宾语不足语。e.g.She made her mother angry.

  4.形容词在句中的位置。 形容词做定语修饰名词时,放在名词前面。修饰不定代词时要放在不定代词之后。

  e.g.She is a clever girl.

  I saw something white in the water.

  5.某些形容词前加上定冠词the,可以代表一类人或东西,可以用作主语,宾语等。做主语时当复数看待。

  e.g.The old are well looked after.

  We all love the beautiful.

  二、 形容词的等级变化

  在英语中形容词有原级,比较级和最高级之分。原级就是它们的原形,比较级和最高级有规则变化和不规则变化。

  (一)形容词的比较级和最高级变化

  1.规则变化

  单音节词和部分双音节词

  (1)一般在词尾加er,est. hard---harder---hardest great---greater---greatest

  (2)以字母e结尾的加r,st. nice---nicer----nicest able---abler----ablest

  (3)重读闭音节中末尾只有一个辅音字母时,双写辅音字母,再加er,est.

  big---bigger---biggest (另外还有fat, red,hot,wet,sad,mad ,thin )

  (4) 以 -y 结尾,但 -y 前是辅音字母的形容词的比较级和最高级是把 -y 去掉,加 上 -ier 和-est 构成. happy (原形) happier (比较级) happiest (最高级)

  (5)双音节和多音节形容词的比较级和最高级需用more 和 most 加在形容词前面来构成。

  例如: beautiful (原级) difficult (原级)

  more beautiful (比较级) more difficult (比较级)

  most beautiful (最高级) most difficult (最高级)

  2、 常用的不规则变化的形容词的比较级和最高级:

  原级 比较级 最高级

  good better best

  many more most

  much more most

  bad worse worst

  little less least

  ill worse worst

  far farther(further) farthest(furthest)

  三、形容词比较等级的用法:

  1、形容词的比较级用于两个人或事物的比较,其结构形式如下:

  主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。例如:Our teacher is taller than we are. 我们老师的个子比我们的高。

  比较级前面可以用even, still, yet , any, much, rather, a little, a lot, by far等修饰语用以加强语气或表示比较程度。

  2、形容词最高级的用法: 形容词最高级用于两个以上的人和物进行比较,形容词最高级 前必须加the,后面多用of……, in……短语表示范围:其结构形式为:

  主语+谓语(系动词)+the+形容词最高级+名词+表示范围的短语或从句。

  She is the best student in her class. 她是班上最好的学生。

  He is the tallest of the three boys.他是三个男孩中最高的一个。

  四、 有关比较等级的特殊句型及应注意的问题

  1. “比较级 + and + 比较级”或“more and more / less and less + 原级”结构表示“越来越……”的意思,与这类结构搭配的常用动词有grow, get, become等。

  She felt herself becoming more and more nervous.她觉得自己越来越紧张。

  it's getting colder and colder.天气越来越冷。

  2. the + 比较级 + of the two + 名词。表示“两个中较···的一个'

  Jane is the taller of the two children in our family. Jane是我家两个孩子中较高的。

  3. “the + 比较级……,the + 比较级……”,表示“越……,越……”。

  The more magazines you sell, the more money you will get.你卖的杂志越多,你挣的钱就越多。

  4.“...as + 形容词 + as...”或“...as + 形容词 + 名词 + as...”构成,表示同等比较。

  常见考法

  对于形容词的考查,多以单选或词语运用的形式考查学生在具体语境中灵活运用形容词的能力,尤其是在各种比较句型中灵活运用形容词。

  例如: Which month is____, June, July or August?

  A. hot B. hotter C. hottest D. the hottest

  解析:三者及以上比较用最高级形式,形容词最高级前必须加the,所以应用the hottest

  误区提醒

  在分辨比较等级时,对于易混淆形容词、副词,要谨慎对待。

  典型例题:Don't just believe the ad.That kind of camera is it says.

  A.as good as B.not so good as C.as well as D.not as well as

  解析:根据第二句的谓语动词be可以确定空白处缺少表语。此处的表语应由形容词充当,而 well表示“好”是副词,因此排除 C和D;根据第一句的意思我们可以知道说话者的观点,故此排除A.

  答案:B

  一、陈述句

  陈述句是陈述一个事实或者说话人的看法的,陈述句分为肯定句和否定句。陈述句句末用句号,朗读时用降调。

  (c)代词:nothing, nobody, none等。 I found nobody about computer. (在那栋房子里我没看到任何人。)

  二、疑问句

  疑问句的主要交际功能是提出问题,询问情况。分为一般疑问句、选择疑问句、特殊疑问句和反意疑问句。

  1、一般疑问句通常用来询问一件事情是否属实。答句通常是"yes或no"。

  句型一:Be +主语+ …? Are these books on the desk? 这些书在桌子上吗?

  一种是:一般疑问句+or+被选择部分?, 这一类选择疑问句通常都是在前一个供选择的答案用低升调,后一个用降调;如果有两个以上供选择的答案,则在最后一个用降调,其余都用低升调。例如: Would you like a gin,or a whisky,or a `beer? 你是要喝杜松子酒,还是威士忌酒,还是啤酒?

  另一种是:特殊疑问句+被选择部分(A)+or+被选择部分(B)?,也是在语调上有所区别。例如: Which vase shall I use, the short one or the tall one ?

  4、反意疑问句又叫附加疑问句,是指当提问的人对前面所叙述的事实不敢肯定,而需要向对方加以证实时所提出的问句。其结构为:前一部分是一个陈述句,后一部分是一个简单的问句。完成后一部分简单问句时,要根据前面陈述句的动词时态和人称来选择适当的助动词进行提问,前后两部分的人称和动词时态要保持一致。如果前一部分用肯定式,后一部分一般用否定式;反之,前一部分为否定式,后一部分要用肯定式,即“前肯定后否定,前否定后肯定”。 例如:They work hard, don’t they?

  She was ill yesterday, wasn’t she?

  They haven't been in beijing for three years,have they?

  .反义疑问句的回答用yes, no, 但是,当陈述部分是否定形式时,回答要按事实。如:

  They don’t work hard, do they? 他们不太努力工作,是吗?

  Yes, they do. 不,他们工作努力。/No, they don’t. 对, 他们工作不努力。

  注意:

  1)当陈述句的主语是everyone, everybody, someone, somebody时,简短问句中的主语通常用they。如果陈述句的主语是非人称的复合词,如everything, something, anything, 则简短问句中相应的人称代词是单数的中性词it。后面的疑问句应表示为:

  I am a student, aren’t I

  Everyone is in the classroom, aren’t they?

  Everything begins to grow in spring, doesn’t it?

  Nobody will go, will they?

  2)当陈述部分是I think/believe/ expect/ suppose/imagine 加从句时,疑问句应和从句的人称时态保持一致。 I think chickens can swim, can’t they?

  3)当陈述部分是祈使句时,一般情况下用will you 或 won't you。

  Give me a hand,will you?

  4)以Let's开头的祈使句,疑问句必须用shall we;只有以Let usLet me开头的祈使句,问句才用will you。

  5)There be 句型中,反义疑问部分必须为be 动词 + there.

  6)当陈述部分有never,seldom, hardly,few,little,barely, nothing 等否定词时,后面的疑问句则必须用肯定式。

  常见考法

  对于陈述句和疑问句的考查,常会以单选,完形填空或句子填空的形式出现。考查知识点往往集中在反意疑问句的构成与回答、选择疑问句或陈述句与疑问句的转换方面。

  典型例题:I don't think he is bright, ?

  A is he B isn't he C do I D don't I

  解析:本题考查反意疑问句的构成。当陈述部分是I think 加从句时,疑问句应和从句的人称时态保持一致。所以排除C和D;主句部分don't表明是否定句,所以后面应用肯定形式。

  答案:A

  误区提醒

  对于反意疑问句的回答,一定要根据事实来回答,尤其是“前否定,后肯定”的反意疑问句的回答,更是我们容易出错的地方,一定要注意哦!

  典型例题:——You've never seen dinosaur eggs, have you?

  ——_________. How I wish to visit the Dinosaur World.

  A Yes, I have B No, I haven't C No, I have D Yes, I haven't

  解析:本题考查反意疑问句的回答。根据答语“我多么希望去参观恐龙世界”可知他没去过恐龙世界,没见过恐龙蛋,根据“Yes+肯定事实”和“No+否定事实”的原则,可以得出答案。

  答案:B

  在复合句中,修饰某一名词或代词的从句叫做定语从句,它的作用相当于形容词,被修饰的词叫做先行词。

  1、定语从句的位置。

  1)定语从句一般地说要放在先行词之后,无论这个词在句中充当何种成分。

  The student who answered the question is bill.

  2)有时先行词后还有一个作定语的词或词组时,定语从句则应放在上述成分之后。

  Do you know anyone in our class whose father is a business man?

  2、定语从句的引导词

  1)定语从句的引导词是由关系代词或关系副词充当的。

  关系代词有who/whom/whose/that,关系副词有when/where/why,它们除了引导从句的作用外,还要在从句中充当一定的成分。关系代词和关系副词的选用要看其在从句中发挥的作用,与主语没有任何关系。

  在从句中充当主语的有who/which/that.

  在从句中充当宾语的有whom/which/that.

  在从句中充当定语的有whose.

  在从句中充当状语的有when/where/why.

  当定语从句所修饰的先行词是人时,关系代词要用who(主格),whom(宾格),也可以用that,以及whose(所有格),先行词是物时,关系代词要用which,也可用that.whom/which/that在从句中作宾语时往往可以省略。

  例如:

  The students who do not study hard will not pass the examination.

  Do you know the man(whom)mr green shook hand with?

  The letter(which)I received yesterday is from my sister.

  Who is the man(that)is reading a magazine over there?

  The book(that) you lent me is very ingteresting .

  I will never forget the day when I joined the party.

  Last year I went to the village where I was born.

  This is the reason why she will go to london.

  2)在先行词相同的情况下,根据它们在定语从句中所起的语法作用,可用不同的引导词连接不同的定语从句。

  例如:

  This is the school where I students for six years.(school或student的状语)。

  This is the school which he mentioned just now.(school作menttioned的宾语).
