一般现在时及三单(综合)

时态一:一般现在时/动词第三人称单数

一、定义:1、经常性、习惯性的动作;

2、事物或人物的特征或状态;

3、客观现实、真理或规律。

Example:

1. 表示经常性、习惯性、永久性、频率性的动作,通常与副词often, usually, always, every day (year/ month ), once (twice, three times) a day(week/moth/year), sometimes,in the morning/afternoon/evening,on Sundays等时间状语连用。

They usually go to school by bike.

I take the medicine three times a day.

She helps her mother once a week.

2.表示事物或人物的特征、状态

Mary’s father is a policeman.

There are 50 students in my class.

3. 表示客观真理,科学原理,自然现象等客观事实或格言、谚语等。

The sun rises in the east and sets in the west every day.

The man who has never been to the Great Wall is not a real man.

Tomorrow is Tuesday.

二、结构:

肯定句:主语+ v原/v“三单”(主语+ Be/情态动词/行为动词(原形或三单)+其它)

否定句:主语+Be/情态动词/do/dose+not+其它

一般疑问句:Be/情态动词/do/dose + 主语+其它

特殊疑问句:特殊疑问词+ Be 动词/情态动词/do/dose + 主语+其它(对主语提问除外)对主语提问的特殊疑问句= 特殊疑问词+主语+动词原形/三单(肯定句的结构)+?

总结:行为动词表示具体的动作,be动词表示状态,情态动词表示态度。在做肯定陈述的时候,运用的规则是:有do无be;无do一定要加be。

另外,一定要小心:在做句型转换(否定、疑问)的时候,要分别遵守自己的约定:行为动词要请do/does帮忙;有be就直接用be(be提前变成问句,在后面加上not变成否定句)。

三、第三人称单数(三单)

1、除了我(I )和你(you ) 我们(we)你们(you) 他们(they) 之外都是三单,人称代词he, she, it是第三人称单数。如:

He likes watching TV. 他喜欢看电视。

She has lunch at twelve. 她十二点吃午餐。

It looks like a cat. 它看起来像只猫。

2、单个人名、地名或称呼作主语;是第三人称单数。如:

Han Mei looks like her mother. 韩梅看起来像她的母亲。

Beijing is in China. 北京在中国。

Uncle Wang often makes cakes. 王叔叔经常做蛋糕。

3、单数可数名词或"this / that / the+单数可数名词"作主语时,是第三人称单数。如:

A horse is a useful animal. 马是有用的动物。

This book is yours. 这本书是你的。

That car is red. 那辆小汽车是红色的。

The cat is Lucy's. 这只猫是露茜的。

4、不定代词someone, somebody, nobody, everything, something等及指示代词this, that 作主语时,是第三人称单数。如:

Everyone is here. 大家到齐了。

There is something wrong with the watch. 这块手表有毛病。

This is a pen. 这是一支钢笔。

That is an eraser. 那是一块橡皮擦。

5、不可数名词作主语时为第三人称单数。如:

The milk is in the glass. 牛奶在玻璃杯里。

The bread is very small. 那面包很小。

6、当数字或字母作主语时,看作第三人称单数。如:

"6" is a lucky number. "6"是个吉利数字。

"I" is a letter. "I"是个字母。

四、动词三单变化规则

1、一般情况下加S :

ask---asks learn----learns work---works get---gets like—likes

play—plays stay---stays

2、以“s, x, ch, sh,o”结尾的,在词尾加“es”:

teach-teaches wash----washes go-goes do-does

3、以辅音字母加“y”结尾的,先将“y”变为“i”,然后在加“es”:

study-studies fly-flies cry---cries try---tries carry-carries worry-worries

4、以元音字母加Y的,直接加S,(此种情况可直接归入第1类)

如say—says

5、记住3个特殊的:

Be动词(is are)的三单-is

have的三单-has

Do的三单—does

五、句型转换

一、陈述句变一般疑问句、否定句

1、Be型、情态动词型

否定句:直接在be动词或情态动词后面加not.

疑问句:则把be动词或情态动词(can,could等等)提到主语的前面

例:①陈述句:She is a student.

疑问句→ Is she a student?

否定句→ She is not a student.

②陈述句:I can swim.

疑问句→ Can you swim?yes,I can. No,I can’t.

否定句→ I can not swim.

2、Do型

否定句:主语+ don’t/ doesn’t + 谓语动词原形

疑问句:Do / Does + 主语+ 动词原形

例:①陈述句:We get up at 7:00 every morning.

否定句→We don’t get up at 7:00 every morning.

疑问句→Do you get up at 7:00 every morning?

②陈述句:She has a little brother.

否定句→ She doesn’t have a little brother.

疑问句→ Does she have a little brother?

3、注意“变变变变”

(1)I、we—>you、you

(2)句号变问号;

(3)Does(三单)、Did(过去式)来帮忙,动词变V原;

(4)some->any something->anything somebody-> anybody already->yet too->either

both->neither all->none

eg:

Are you from Japan﹖Yes, I am./ No, I'm not.

Is her sister doing her homework now﹖Yes, she is./ No, she isn't.Does he work in a bank﹖Yes, he does./ No, he doesn't.

Do you live near your school﹖Yes, I do./ No, I don't.

Can you speak French﹖Yes, I can./ No, I can't.

May I go home now﹖Yes, you may./ No, you mustn't.

二、陈述句变特殊疑问句(不能用yes/no回答的疑问句)

1、常见的疑问词

when:问时间(回答用At/ On...等)

where:哪里(状语)

who :谁( 回答用He is...She is... They are...等)

whom:谁(宾格)

whose:谁的(回答用It is.. These/Those are等)

what :什么

How:怎么样(对近况提问,回答用形容词,问程度)

which:哪一个,哪个

常见的疑问短语

what time:问时间点

what weather:什么天气

what subject:什么学科

what job:什么职业

How much:多少钱价格(不可数)

How long:多长(可用于时间,问做多长时间)

How often:多少次(问频率)(频率副词)

How far:多远路程

How soon:多久

How old:多少岁

2、特殊疑问句有两种语序:

(1)如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序:

Who is singing in the room﹖

whose bike is broken﹖

(2)如疑问词作其他成分,即对其他成分提问,其语序是:特殊疑问词+一般疑问句【即:特殊疑问词+be/助动词/情态动词+主语+谓语】

What does she like?

What class are you in﹖

Where are you from﹖

What time does he get up every morning﹖

How do you know﹖

(3)就划线部分提问解题方法:一换二变三提前

一换:找出正确的疑问词或词组替换划线部分

什么东西->what, 地点->where 时间->when, 怎么样->how

多少->how many(可数) how much(不可数)

动作划线->看形式,然后选择助动词,做的事情用what Eg: They read English books in the afternoon. What

They read English books in the classroom every day. Where

They read English books in the classroom in the morning. When

I have got five books. How many

I go to school by bike every day. How

Tom sings songs in the living room every evening. does what

We read books every day. do what

二变:将替换完的句子根据规则变为一般疑问句

eg: Tom swims in the pool every day.

Does Tom do what in the pool every day?

三提前:将变完的一般疑问句中的特殊疑问词提前

eg: Does Tom do what in the pool every day?

What does Tom do in the pool every day?

注意:I like taking photo in the park.

I like doing what in the park.

What do you like doing in the park?

上一般现在时动词第三人称单数形式练习

动词第三人称单数形式 主语有三单,动词也有三单,快点来习惯,体会在心里,一定要过关. 一、概念 动词第三人称单数:主语是第三人称单数,即谓语动词的发出者是it、she、he、可数名词单数、不可数名词等表示单数概念的词时,实义动词后面要加-s或-es。(注意:若主语不是第三人称单数形式,就直接用动词原形;若主语是三单,后有will等情态动词修饰时,动词也用原形。) 二、动词三单变化规则(只有一般现在时才有第三人称单数) 动词第三人称单数的变化规则及发音规律,同名词单数变复数大致相同,请认真观察。 1、大多数实义动词在词尾加“s”,在清辅音后发音为/ s / ,在浊辅音及元音因素后发音为 / z /。如:speak→speaks /s/ ; come→comes /z/ ; play→plays /z/ 2、以辅音字母加“y”结尾的动词,要先将“y”变为“i”,然后再加“es”,读/z/。 如:study→studies /z/ ; fly→flies /z/ 3、以“s,x,ch,sh”结尾的动词,在词尾加“es”,发音为/ iz / 。 如:teach→teaches /iz/ ; watch→watches /iz/ 4、以“o”结尾的动词,在词尾加“es”。 常出现的两个以“o”结尾的动词go和do后加“es”,读/z/ 。 如:go→goes /z/ ; do→does /z/ 5、记住最为特别的be的三单is ;have的三单是has。 [注意](1)下面两个动词变三单时,原词的元音部分的发音发生了较大的变化,要记忆。 如:do/du:/ →does/d z/ ; say/sei/ → says /sez/ (2)以不发音字母“e”结尾的开音节词,如果尾音是[s],[z]时,加“s”后字母“e”发音,与所加“s” 一起读做[iz]。如: close-closes [iz] 三、动词第三人称单数的句子结构。 1、肯定/否定句 三单+is +表语 . 三单+动词第三人称单数+其他 . 三单+is+not+表语 . 三单+doesn't +动词原形+其他 . 2、一般疑问句 1)当谓语动词是be动词时,一般疑问句结构为“Is+三单+表语?”。它的肯定回答为: Yes, 三单+is. ;否定回答为:No,三单+isn't.。 2)当谓语动词是实义动词时,在肯定句句首加助动词does,即“Does+三单+动词原形+ 其他?”。它的肯定回答为:Yes,三单+does.;否定回答为:No,三单+doesn't.。 3、特殊疑问句 特殊疑问词+一般疑问句 四、要点 1)一定要看准句子的主语是第三人称而且还是单数; 2)经常与频率副词连用:always (一直,总是),usually(通常),often (经常),sometimes (有时),seldom (很少),hardly (几乎不),never (从不),once a day (一天一次),twice a week(一周两次),three times a month(一个月三次)。 如:I often speak Chinese. 我经常说汉语。

be动词的一般现在时有三种形式

be动词的一般现在时有三种形式,即:am, is, are(翻译为“是”) 1. 如果主语是第一人称I(我)时,be动词用am。 如:I am a student. 我是一名学生。 I am 还可缩写成I'm。如:I'm David. 我是大卫。 am 与 not 不能缩写。如:I am not a bad boy.

2. 如果主语是we(我们),you (你,你们), they (他们,它们,她们)或名词复数(两个以上的人或物)时,be动词必须用are。如:Are you twelve? 你是十二岁吗? Tom and Lily are good friends. 汤姆和莉莉是好朋友。 They are at school. 他们在学校。 are与主语还可缩写。

如: We are= We're, They are =They're, You are = You're。而are与 not可缩写成aren't。如:They aren't students. 他们不是学生。 3. 如果主语是单数名词、不可数名词或单数第三人称代词(he, she, it)时,be动词用is。如:My mother is a teacher. 我的妈妈是一名老师。 He is a student. 他是一名学生。 is也可与主语缩写,

如: He is = He's, My mother is = My mother's 等。但是This is不可缩写。而is与not可缩写成 isn't。如:This isn't a book. 这不是一本书。 4. 句中含有be动词的陈述句变一般疑问句。把be动词提到句首,be动词要变大写。注意第一人称变第二人称。回答时用yes或no表示,结构:Yes, 主语+be动词,No,主语+be动词+not。如:It is a book. 变为:

英语动词分类+动词时态之一般现在时(含练习)

动词分类+一般现在时(一) 一、动词分类 动词是英语词类中最重要的一种。动词按其词义和在句中的作用可分为: 及物动词 实义动词 不及物动词 系动词 动词 情态动词 助动词 1.实义动词(有实际意义的动词,可在句中独立做谓语): 及物动词可以直接加宾语(study/ learn/ eat/ drink/ wash…) 不及物动词不能直接加宾语,但是不及物动词+介词+宾语(常见动词有:listen to/ look at/ speak to…) 2.系动词+形容词 1)感官动词:feel; sound; smell; taste; look +形容词(当look 做实义动词讲时为不及物动词) 2)be/ seem+形容词 3)表变化的词:get/ turn/ become/ go+形容词(get/ turn/ go当实义动词讲是意思分别为:得到/ 轮流/ 去、走) 3.助动词无实际意义,在句中不能独立做谓语,have/ do 既可以做助动词也可 以做实义动词(先做简单了解,之后讲动词时态时会经常见到) eg1. I have a bike. (have是实义动词) eg2. They have gone to Beijing. (have是助动词) eg3. I do my homework everyday. (do 是实义动词) eg4. I do like English. (do 是助动词) 4.情态动词(情态动词在句中不可独立做谓语) 常见情态动词:may, might, can, could, must, shall, should, will, would, had better, need(此处不做重点,之后会做情态动词专题)

动词及一般现在时分析

英语语法专题 ——动词及其八种时态之一般现在时 本课重点:1.动词分类:实义动词,连系动词,助动词,情态动词; 2.动词的词型变化; 3.一般现在时的具体用法 动词是表示动作或状态的词。句子中的谓语成分是由动词充当的,谓语通常是句中不可缺少的成分,因此动词是英语词类中最重要的一种。动词可以通过本身的变化来表示动作发生的时间以及说话人的语气、态度等。 一、动词的分类: 动词按其词义和在句中的作用可以分为:行为动词(或称实义动词)、连系动词、助动词和情态动词。详见下表: verb)两大类。谓语动词又称限定动词,非谓语动词又称非限定动词。非谓语动词初中阶段主要学习动词不定式的用法。 1、实义动词: ①英语的实义动词又可分为及物动词和不及物动词两大类: 后面必须跟宾语意义才完整的叫及物动词;本身意义完整,后面不需跟宾语的叫不及物动词。 ②有些动词通常只作不及物动词。如:go,come,happen,lie,listen,rise,arrive,hall等。 有些动词通常用作及物动词。如:say, raise, lay, find, buy等。 ③大多数动词可以兼作及物动词和不及物动词。如:study, sing等。 ④有些动词作及物动词与作不及物动词时的意义有所不同。如:know, wash等。 ⑤有些动词常和介词、副词或其它词类一起构成固定词组,形成短语动词。如:listen,reply,wait,look. 2、连系动词: ①连系动词用来连接主语和表语,连系动词后面常为形容词。 ②常见的连系动词有:be、become、look、feel、sound、smell、taste、seem、turn、grow、 ③get、go、fall、sit、stand、lie 等。 ④有些连系动词来源于实义动词,意思也跟着变化:look(看→看起来)、feel(感觉、摸→感到)、smell(闻、嗅→闻起来)、taste(尝→尝起来)、turn(翻转、转动→变得)、grow(生长→变得)、
