主谓一致和倒装句主谓一致:一、语法一致原则1、以and或both...and...连接名词作主语时,如果该并列主语指的是两个或两个以上的人或事物,谓语动词用复数形式;如果该并列主语指的是同一个人或事物(即and后面的名词前没有冠词),则谓语动词要用单数形式。
and连接并列主语,若前面有each, every, many a, no等词修饰时,谓语动词用单数形式。
如:Eating vegetables and doing exercise are good for our health.The teacher and writer is coming to give us a report next week..Each boy and each girl has got a present.2、不定代词another, each one, either, neither, the other, somebody, someone, something, nobody, everybody, everyone, everything, nothing, anybody, anything, anyone no one等作主语时,谓语动词用单数形式。
如:Everyone is getting ready for the exam.3、主语后面跟with, along with, like, except, besides, as well as, together with, including, no less than, rather than, as much as等词或短语时,谓语动词的数与主语保持一致。
如:Mei Mei, together with her parents, often goes to the park on Sunday.4、a number of +复数名词作主语时,谓语动词用复数形式;the number of +复数名词作主语时,谓语动词用单数形式。
动词时态、语态和主谓一致高三英语一轮复习考点剖析-动词时态、语态和主谓一致考点一:考查过去进行时例1.I first met Lily five years ago. She ________ (work) as a nurse in a hospital at the time.【答案】was working【解析】考查时态。
句意:我五年前第一次见到莉莉。
她当时正在一所医院里做护士。
根据句意和时间状语at the time 可知,这里用过去进行时,强调过去某个时刻正在进行的动作,主语为she,谓语用单数。
故填was working。
考点二:考查一般过去时例2.He picked up his book and ________ reading even though it was already midnight. (continuous)【答案】continued【解析】考查时态。
句意:他拿起书继续阅读,尽管已经是午夜了。
所给单词continuous是形容词,表示“持续的”,分析句子机构,空处与picked并列作谓语,应用动词continue,表示“继续”,根据picked使用过去式形式可知,句子使用一般过去时,动词应用过去式形式continued。
故填continued。
考点三:考查现在进行时例3.—Hi, Jessy. Why are you going to work on foot today?—Well, my car ________. (repair)【答案】is being repaired【解析】考查时态和语态。
句意:——你好,杰西。
你今天为什么要步行去上班?——嗯,我的车正在修理。
根据句意提到步行上班可知,此处表示:车在修理中,时态用现在进行时,主语my car与repair(修理)之间为被动关系,所以用现在进行时的被动语态。
主语my car为单数,be动词用is。
考点四:考查现在完成时例4.The city ________ (recognize) as the musical capital of Europe since the 16th century, home to the likes of Mozart and Beethoven.【答案】has been recognized【解析】考查时态语态。
讲义·主谓一致谓语动词三要素:主被动、时态、主谓一致(虚拟语气、情态动词)主语和谓语动词在单、复数形式上的一致,就是主谓一致。
也就是,如果名词中心词是单数,动词用单数形式;如果名词中心词是复数,动词用复数形式。
My family _is_ (be) a big one.My family _are_ (be) watching TV.family = 整体(一个家)= 单数family = 家庭里所有的成员= 复数【壹】语法形式一致原则一、主语中心词后面有表示“增、减、补充说明”的词组时,主谓一致仍看中心词表示增加的:as well as, with, along with, together with, in addition to, accompanied by, besides, plus等along with 和in addition to 除此之外(包含前面的内容)besides 除此之外(包含前面的内容)accompanied by 跟随着……plus 加上,还有The man (together with his wife and children) sits on the sofa watching TV.那个人和他妻儿老小坐在沙发上看电视。
The man, his wife and their children sit on the sofa watching TV.and是并列连词表示减去的:except, but(除去)等All the students (except Tom) have been to America.除汤姆外,其他学生都去过美国。
I want nobody but you.表示补充说明的:including, rather than, like(像), such as等The text book, plus its reference books, is well designed.这本教材,还有参考书,设计的都很好。
情态动词and主谓⼀致情态动词的定义:情态动词是⼀种本⾝有⼀定的词义,表⽰说话⼈的情绪,态度或语⽓的动词,但不能单独作谓语, 只能和其他动词原形构成谓语。
We can be there on time tomorrow.我们明天能按时去那⼉。
May I have your name?我能知道你的名字吗?Shall we begin now?我们现在就开始吗?You must obey the school rules.你必须遵守校规。
情态动词数量不多,但⽤途⼴泛,主要有下列:can (could), may (might), must,mustn't , need, ought to, dare (dared), shall (should), will (would) .情态动词的位置:情态动词在句中放在谓语动词之前, 谓语动词前若有助动词,则在助动词之前,疑问句中, 情态动词则在主语之前。
I can see you. Come here。
我能看见你,过来吧。
He must have been away.他⼀定⾛了。
What can I do for you?你要什么?How dare you treat us like that!你怎能那样对待我们!情态动词的特点:情态动词⽆⼈称和数的变化, 情态动词后⾯跟的动词需⽤原形,否定式构成是在情态动词后⾯加 "not"。
个别情态动词有现在式和过去式两种形式, 过去式⽤来表达更加客⽓, 委婉的语⽓, 时态性不强, 可⽤于过去,现在或将来。
He could be here soon。
他很快就来。
We can't carry the heavy box.我们搬不动那箱⼦。

主谓一致的用法一、什么叫主谓一致?主谓一致:是指谓语动词与主语在人称和数上保持一致二、根据主语定谓语1.名词做主语可数名词单数做主语,谓语动词用单数形式可数名词复数做主语,谓语动词用复数形式不可数名词做主语,谓语动词用单数形式(1)主系表结构可数名词单数做主语,用be动词is可数名词复数做主语,用be动词are不可数名词做主语,用be动词is例:The girl is beautiful.The girls are beautiful.Water is necessary for us to live.(2)主谓宾结构可数名词单数做主语,谓语动词用单三形式可数名词复数做主语,谓语动词用原形不可数名词做主语,谓语动词用单三形式例:The girl likes playing the piano.My friends often play basketball on weekends.2.代词做主语(1)主系表结构主语为I时, 用be动词am主语为She/He/It时,用be动词 is主语为We/You/They时,用be动词are(2)主谓宾结构主语为She/He/It时,谓语动词要使用“三单”形式主语为I/We/You/The y时,谓语动词在一般现在时中用动词原形,在过去时中用过去式3.There be句型is+不可数名词/可数名词Thereare+可数名词复数4.情态动词(can/must/will/should/...)做谓语无论句子的主语是什么人称或数,情态动词以及情态动词后的动词都用原形5.特殊情况(1)当不定代词做主语时,谓语动词用单三常见的不定代词有:everyone/anyone/no one/someone/something/anything/everything/nothing(2)当主语是pants/trousers/shoes等复数名词时,谓语动词用复数;但若前面加上单数量词时,谓语动词用单数。
主谓一致与主语与谓语部分一致全面解读主谓一致是语法中一个重要的原则,即主语与谓语在人称和数上要保持一致。
主语与谓语要在人称和数上相对应,以确保句子的语法正确性。
主语是句子中的动作的执行者或者是句子主题的核心,而谓语则是句子中表达动作或状态的部分。
在主谓一致中,首先要注意的就是人称的一致性。
当主语是第一人称(我、我们)时,谓语动词也要使用第一人称形式(如使用I、We)。
当主语是第二人称(你、你们)时,谓语动词也要使用第二人称形式(如使用You、You)。
当主语是第三人称(他、她、它、他们、它们、她们)时,谓语动词也要使用第三人称形式(如使用He、She、It、They)。
接下来,我们要关注主语与谓语在数上的一致性。
当主语是单数形式时,谓语动词也要使用单数形式(如动词加“s”或者“es”)。
当主语是复数形式时,谓语动词也要使用复数形式(如动词不加“s”或“es”)。
除了在一般情况下主谓一致的原则外,还有一些特殊情况需要特别注意。
例如,当主语是由“and”连接的两个或多个名词时,谓语动词要使用复数形式。
当主语是由“either...or”或“neither...nor”连接的两个名词时,谓语动词要与靠近它的名词在数上保持一致。
当主语是由“every...”或“each...”开头的名词时,谓语动词要使用单数形式。
当主语是由“more than...”或“less than...”连接并进行比较的两个名词时,谓语动词要与比较级后面的名词在数上保持一致。
总的来说,主谓一致在英语语法中是一个非常基本的规则。
遵循这个规则能够使句子更加流畅、准确,并且避免语法错误的出现。
要注意主语与谓语在人称和数上的一致性,并特别留意那些特殊情况下的一致性规则。
主语与谓语部分一致也是我们解读句子时需要注意的一个方面。
主语与谓语部分一致要求句子中除了主语与谓语的人称和数要保持一致外,还要求这两个部分在时态、语态等方面也要保持一致。
动词的种类和主谓一致张兵一、动词的种类:动词可以分为连系动词、助动词、情态动词和实义动词四类。
1、连系动词亦称系动词。
系动词本身有意义,如:be(是), keep(保持),remain(停留、保持),stay(保持),seem(似乎、看起来),look(看起来), appear(表现的), feel(感觉起来), sound(听起来), smell(闻起来), taste(尝起来), become(变得), grow(变得), turn(变得), get(变得), go(变得)等等,连系动词+表语(名词、形容词、不定式、介词短语或者句子等)一起构成句子的谓语,也称系表结构,主要用于说明主语的身份、状况、性质、特征等。
He is a teacher.He always keeps silent at meeting.He looks tired.He seems (to be)tired.He became mad after that.His aim is to be a successful man.His backpack is on the sofa.His achievement is that he overcame all the enemy in this match.2、助动词:本身没有意义,不能独立作谓语,在句中和行为动词或者连系动词一起构成各种时态、语态、语气、疑问、否定等。
(1)、助动词be“助动词be+现在分词”构成进行时态。
They are boating on the lake.“助动词be+过去分词”构成被动语态。
The book was written by Lu Xun.“助动词be+going to +动词原形”表示计划、打算做某事。
I am going to take a plane to Hong Kong next week.(2)、助动词dodo/does 帮助构成一般现在时态的否定句和疑问句。
动词(短语)表示主语的动作、存在、变化或态度。
动词按照动词的意义可以分为实义动词、情态动词、系动词、助动词。
谓语动词的时态、语态和主谓一致动词时态历来是高考考查的重点。
动词时态考查虽多,但考向非常集中,最常考的是一般过去时和一般现在时,其次是现在完成时,其他时态考查相对较少。
因此备考重点是:①动词时态的基本用法②动词语态的基本用法③主谓一致动词时态的知识网络(以动词do为例)1.一般时态(1)一般现在时①表示经常或习惯性的动作,多用动作动词,且常与表频率的时间状语连用。
We have meals three times a day.我们一日吃三餐。
②表示客观真理、科学事实及自然现象。
The sun sets in the west.太阳从西方落下。
③在时间、条件状语从句中常用一般现在时代替一般将来时。
I’ll write to her when I have time.有时间我会写信给她。
(2)一般过去时①表示过去发生的一次性或习惯性动作或状态。
We often played basketball together.我们(过去)经常在一起打篮球。
②时间、条件、让步状语从句中,若主句用了过去将来时,从句常用一般过去时。
He said he would tell her the news as soon as he met her.他说他一见到她就把这个消息告诉她。
单句语法填空①The 80,000 objects collected by Sir Hans Sloane, for example, formed (form) the core collection of the British Museum which/that opened in 1759.(2020·新高考卷Ⅰ语法填空)②The unmanned Chang’e-4 probe (探测器)—the name was inspired by an ancient Chinese moon goddess—touched (touch) down last week in the South Pole-Aitken basin.(2020·全国卷Ⅰ语法填空)③When/As he asked the villagers on the banks of the river where he could find the legendary (传奇的) artist, they smiled and pointed (point) down the river.(2020·全国卷Ⅲ语法填空)④New methods meant__(mean)that fewer people worked in farming.(2020·浙江卷语法填空)⑤While running regularly can’t make you live forever,the review says it is(be) more effective at lengthening life than walking,cycling or swimming.(2018·全国卷Ⅰ语法填空)⑥Sarah says,“My dad thinks I should take the offer now.But at the moment,school comes (come) first.I don’t want to get too absorbed in modeling.”(全国卷Ⅲ语法填空)2.进行时态(1)现在进行时(am/is/are+现在分词)①表示说话时正在进行或发生的动作,也可表示现阶段正在进行的动作或存在的状态。
英文写作中的主谓一致和时态变换在英文写作中,主谓一致和时态变换是两个重要的语法规则。
正确运用主谓一致和时态变换可以使文章更加流畅和准确。
本文将探讨这两个语法规则的基本概念和运用技巧。
主谓一致是指主语和谓语在人称和数上保持一致。
即当主语是单数第三人称时,谓语动词要使用单数形式;当主语是复数或单数第一、第二人称时,谓语动词要使用复数形式。
例如,“He runs every morning.”中,主语是单数第三人称“He”,谓语动词“run”使用了单数形式。
主谓一致的原则也适用于其他形式的谓语,如助动词、情态动词等。
要正确运用主谓一致,需要注意一些特殊情况。
首先,当主语由多个并列成分组成时,谓语动词与最近的主语保持一致。
例如,“John, along with his friends, is going to the party.”中,谓语动词“is”与最近的主语“John”保持一致。
其次,当主谓之间有插入语时,插入语不影响主谓一致。
例如,“The dog, barking loudly, runs after the ball.”中,插入语“barking loudly”不影响谓语动词“runs”的单数形式。
时态变换是指随着时间的推进,动词的形式和用法发生的变化。
在英文写作中,时态的准确运用可以表达事件的发生顺序和持续状态。
常用的时态包括一般现在时、一般过去时、一般将来时等。
对于一般现在时,用来表示现在的情况、经常性的动作或普遍真理等。
例如,“He plays basketball every day.”中,谓语动词“plays”表示经常性的动作。
对于一般过去时,用来表示过去的情况或事件。
例如,“She studied hard for the exam.”中,谓语动词“studied”表示过去的动作。
对于一般将来时,用来表示将来的情况或计划。
例如,“I will go shopping tomorrow.”中,谓语动词“will go”表示将来的行为。
情态动词的定义:情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语, 只能和其他动词原形构成谓语。
We can be there on time tomorrow.我们明天能按时去那儿。
May I have your name?我能知道你的名字吗?Shall we begin now?我们现在就开始吗?You must obey the school rules.你必须遵守校规。
情态动词数量不多,但用途广泛,主要有下列:can (could), may (might), must,mustn't , need, ought to, dare (dared), shall (should), will (would) .情态动词的位置:情态动词在句中放在谓语动词之前, 谓语动词前若有助动词,则在助动词之前,疑问句中, 情态动词则在主语之前。
I can see you. Come here。
我能看见你,过来吧。
He must have been away.他一定走了。
What can I do for you?你要什么?How dare you treat us like that!你怎能那样对待我们!情态动词的特点:情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 "not"。
个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去,现在或将来。
He could be here soon。
他很快就来。
We can't carry the heavy box.我们搬不动那箱子。
I'm sorry I can't help you。
对不起,我帮不上你。
情态动词的用法:can (could) 表示说话人能,可以,同意,准许,以及客观条件许可,could 为 can 的过去式。
Can you pass me the books你能给我递一下书吗 ? Could you help me, please?请问,你能帮助我吗?What can you do?你能干点什么呢? Can you be sure?你有把握吗?can 和could 只能用于现在式和过去式两种时态,将来时态用 be able to 来表示。
He could help us at all.他完全可以帮助我们。
With the teacher's help,I shall be able to speak English correctly.由于老师的帮助,我将能准确地讲英语。
may (might) 可以, 表示说话人同意,许可或请求对方许可。

may 否定式为 may not, 缩写形式是 mayn't.might 是may 的过去式, 有两种用法, 一种表示过去式,一种表示虚拟语气, 使语气更加委婉, 客气或对可能性的怀疑。
He told me he might be here on time.他说他能按时间来。
Might I borrow some money now.我可以借点钱吗?He might be alive.他可能还活着。

must 和 have to 的区别: must 表示说话人的主观思想, have to 表示客观需要。

(说话人认为必须现在干)I have to go now. 我得走了。
(客观条件必须现在走)回答must 提问:(1)肯定回答:Yes,----must.(2)否定回答:No,--needn't./No,---don't/doesn't have to.need 需要多用在否定式或疑问句.Need I attend the meeting tomorrow? 我需要明天参加会议吗?You need not hand in the paper this week. 这一周你不必交论文。
need 是一个情态动词, 他的用法完全和其他情态动词一样, 但 need 还可当作实义动词使用, 这时 need 就象其他动词一样,有第三人称,单复数, 后面加带 to 的动词等特性。
I need a bike to go to school. 我上学需要一辆自行车。
Do you need a dictionary?你需要词典吗?She needs a necklace. 她需要一条项链。
