实意动词单数第三人称变化规律:

注意:不规则变化的有have—has, be—is, go—goes, do—does

一般现在时,当主语是第三人称单数时,谓语动词要用第三人称单数形式 
主语是第三人称单数有以下几种情况: 

(1) 不可数名词做主语:
Some water is in the glass 

(2) 单个的可数名词做主语:

The girl is Chinese.  My watch is on the dresser. 

(3) He ,she , it 等代词单个做主语: 
He is in the tree. She likes her family very much.

Mary is a doctor.  Uncle Li speaks a little English.   
Changchun is a beautiful city. 

(5) 指示代词this, that 等作主语:
 This is a pear.  That is an apple . 

(6) Everyone, everything ,something, nobody, nothing.等不定代词作主语时 
Is everyone here today?   Everything is ok . 

(7)单个数字作主语时:
”8” is a good number in China.

主语(单三)+doesn + 动词原形+其他 

Jim likes football变否定: Jim doesn’t like football             

He has lunch at school. 变否定:He doesn’t have lunch at school.   


一般疑问句及答语,在句子前面加助动词

Does +主语(单三)动词原形+其他 

Does your father work ? Yes, he does. /No, he doesn’t    


特殊疑问句:特殊疑问词
+一般疑问句 

特殊疑问词+ does +主语(单三)动词原形+其他         

Where does a bird live ?

实意动词:
即行为动词,表示动作的动词。实义动词与系动词是相对的,能独立用作谓语。
它分为及物动词和不及物动词两种:
及物动词是指后面要求有直接宾语的动词;
不及物动词指后面不需要跟宾语的动词。

实意动词使用方法:
及物动词
后面必须跟宾语意义才完整的实义动词,叫做及物动词(transitive verb)。如:
I believe that the committee will consider our suggestion.我相信委员会将会考虑我们的建议。
“How long can I keep the book ?”Harry asked.哈里问:“这本书我可以借多久?”
Dr. Bethune set us a good example. 白求恩大夫给我们树立了好榜样。
Crude oil contains many useful substances.原油含有许多有用的物质。

不及物动词
本身意义完整后面不须跟宾语的实义动词,叫做不及物动词(intransitive verb)。如:
Birds fly.鸟会飞。
It happened in June 1932.这件事发生于一九三二年六月。
My watch stopped.我的表停了。
She spoke at the meeting yesterday evening. 她在昨天晚上的会上发了言。

兼作及物动词和不及物动词
英语里有不少实义动词可以兼作及物动词和不及物动词。这样的动词又有两种不同的情况
a)兼作及物动词和不及物动词时,意义不变。试比较:
Shall I begin at once?我可以立刻开始吗?(begin作不及物动词)
She began working as a librarian after she left school.她毕业后当图书馆管理员。(began作及物动词)
When did they leave Chicago?他们是什么时候离开芝加哥的?(leave 作及物动词)
They left last week. 他们是上周离开的。(left 作不及物动词)
b)兼作及物动词和不及物动词时,有时意义不尽相同。如:
Wash your hands before meals.饭前要洗手。
Does this cloth wash well? 这布经得起洗吗?


英汉实意动词用法比较:
与汉语的比较,有时英语动词的及物和不及物的用法,与汉语的用法不一样,请注意下列两种情况:
a)有的动词在英语里只能用作不及物动词,而汉语则可用作及物动词,如arrive到达,agree同意,listen听。英语里这些动词后面常接介词。如:
We arrived at the railway station at noon.
我们于中午到达火车站。(at不能省去)
(比较:We reached the railway station at noon.)
Everybody listened to the lecture with great interest.
每个人都很有兴趣地听讲课。(to不可省去)
(比较:We all heard the lecture.)
Do they agree to the plan?他们同意这个计划吗?(to不可省去)

b)有的动词在英语里能用作及物动词,而在汉语里则不能用作及物动词,如serve为…服务。
Our children are taught to serve the people wholeheartedly.
我们的儿童被教以全心全意为人民服务
用于be动词之后,实义动词之前。

 实意动词的用法:
肯定句:
主语+动词过去式+其它
否定句:
主语+助动词didn‘t+动词原型+其他
一般过去式:
Did+主语+动词原型+其他


系动词
亦称连系动词。作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语,亦称补语(形容词),构成系表结构说明主语的状况、性质、特征等情况。
系动词的分类:
1)状态系动词
用来表示主语状态,只有be一词,例如:
He is a teacher. 他是一名教师。(is与补足语一起说明主语的身份。)
2)持续系动词
用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand, 例如:
He always kept silent at meeting. 他开会时总保持沉默。
This matter rests a mystery. 此事仍是一个谜。
3)表像系动词
用来表示"看起来像"这一概念,主要有seem, appear, look, 例如:
He looks tired. 他看起来很累。
He seems (to be) very sad. 他看起来很伤心。
4)感官系动词
感官系动词主要有feel, smell, sound, taste, 例如:
This kind of cloth feels very soft.
这种布手感很软。
This flower smells very sweet.
这朵花闻起来很香。
5)变化系动词
这些系动词表示主语变成什么样,变化系动词主要有become, grow, turn, fall, get, go, come, run.
例如:
He became mad after that. 自那之后,他疯了。
She grew rich within a short time. 她没多长时间就富了。
6)终止系动词
表示主语已终止动作,主要有prove, turn out, 表达"证实","变成"之意,例如:
The rumor proved false. 这谣言证实有假。
The search proved difficult. 搜查证实很难。
His plan turned out a success. 他的计划终于成功了。(turn out表终止性结果)

系动词使用的注意事项:
系动词本身有一定的词义,不能单独作
谓语,后面必须与表语连用。复习系动词时,必须注意以下几个问题:

1.be是最重要的系动词,主语不同,be的形式也不同,且有时态的变化。

a通常表示主语的特征、状态和身份等,后面接形容词、副词、名词、介词短语、不定式v-ing过去分词表语从句作表语。

b特别要注意be+过去分词所构成的系表结构be+过去分词所构成的被动语态的区别。

c前者侧重于表示主语的特征或所处的状态,通常没有由by引导的介词短语。

如:The door was closed.

后者侧重于强调主语是谓语动词所示动作的承受者,表示动作;句中可以用由by引导的介词短语。如:The door was closed by me.

d还要注意be+ V-ing所构成的系表结构be+ V-ing”所构成的进行时态的区别。

前者侧重于说明主语具有的特征或存在的状态,也可说明主语是什么。如:My job is teaching English.

后者侧重于强调主语正在做某事。如:Mr Wang is reading an evening paper now.


2.
要注意由行为动词转化成的系动词。

a表示人体感官的系动词有soundtastelookfeelsmell等,后面接形容词;

b表示主语从一种状态转变到另一种状态的系动词有becomegetgoturnrungrowcomefallprove等,后面接形容词、名词或 to be+形容词,become后面接单数名词时,名词前要用不定冠词turn后面接单数名词时,名词前不用不定冠词

c表示主语继续或保持某种身份、特征状态的系动词有continuekeepremainstaystand liereststay等,后面接表示状态的形容词;

d表示判断的系动词有seemappear,后面接形容词、to be+名词或形容词、that-clause、不定式等。


3.
要注意系动词的固定搭配。常见的有come true, fall asleep, fall ill, go bad, come right, run wild, wear thin, turn nasty等。


4.
要特别注意某些动词既可以做系动词,又可以做实意动词的用法。

系动词部分主要注意:
其后要求接形容词,而不是
副词表语。遇到这种情况,只能先根据其意思判断清楚到底是前者还是后者,然后再对后面的词性和词义做出正确判断和选择。
taste一词为例:

The newly-invented soft drinking tastes quite unique.
(这种新研制的软饮料尝起来挺独特的。
注意:在这句话里,
taste做系动词,不能使用进行时,后面接形容词。)

The chef is tasting the fish carefully.
(厨师长正在品尝这道鱼。
注意:在这句话中,
taste实意动词,可以使用进行时,并且后面接副词做状语。)


系动词用法点拨:
1.系动词的进行时态应分情况讨论。
一般地说,状态系动词无进行时态,而动态系动词有进行时态。
但是在某些情况下,状态系动词也有进行时态,表示两个用途:
一是表示一种短暂的、反常的状态。如:
He is being kind.(一时而不能持久的性质)他装出和蔼可亲的样子。
二是表示一种探询口气,使语言客气、生动、亲切。例如:
I hope you are keeping well.(语气委婉)我希望你保持健康。
Are you feeling any better?(语气亲切)你感觉好了些吗?
试比较:
Your hand feels cold.(无意识的静态性质。)你的手摸起来冰凉。
不可以说:
Your hand is feeling cold.(×)
但可以说:
The doctor is feeling her pulse.(有意识的动态动作)医生正在给她拿脉。
The soup tastes good.(静态性质,无进行时)这汤的味道不错。
The cook is tasting the soup.(动态动作,有进行时)厨师在尝汤的味道。

总之,系动词有无进行时态应随系动词的意义或其语境变化而变化。
我们在概述某一动词的进行时态时,不能笼统地说feel,smell无进行时,应指出其意义及其语用环境。
例如smell的用法可见一斑。
①smell作“嗅觉”的能力时,虽是实义动词,但指的是一种性质的存在状态不能用于进行时态,常与can, could, be able to连用。
The camels can smell the water a mile off.骆驼能嗅出一英里外有水。
②指“嗅、闻”的动作时,实义动词,可用于进行时态。
The girl is smelling the flower.这姑娘正在闻那朵花。
③smell指“含有……气味”,“发出……气味”等事物性质时,半系动词,无进行时态。
The dinner smells good.这饭菜闻起来真香。

2.系动词的时态与形容词的比较级连用的问题。
某些含有变化意义的动态系动词如get, become, grow, turn等的进行时态可与形容词的比较级连用,表示渐进过程,其意思是“越来越……”。例如:
He is growing taller and taller.他长得越来越高了。
Our life is getting better and better.我们的生活是越来越好了。
The things are getting worse.情况是越来越糟了。

3.所有半系动词的被动语态要分情况讨论。
英语中某动词在作系动词用时,无被动语态,而作实义动词用时,才有被动语态,二者不可混为一谈。例如:
不能说:
The apple is tasted good.
(因为taste此时是系动词,“尝起来”之意,指的是苹果的性质,无被动语态)
但我们可以说:
The apple is tasted by me.这苹果被我尝了一下。
(taste此时指“尝一尝”这一动作,有被动语态)
因此,在平时的英语教学和学习之 ,要有意注意半系动词在具体的语言环境中到底是系动词用法还是实义动词用法,要注意区分、识别。

4.瞬间动态系动词能否与时间段连用的问题
英语中某些表示瞬间意义的系动词不能与“for+时间段,since+时间点,how long until+时间,by + 时间,so far”等直接连用。例如:
①不能说:He has become a teacher for 2 years.
应改为:He has been a teacher for 2 years.
②不能说:He has turned writer since 3 years ago.
应改为:He has been a writer since 3 years ago.
或It is three years since he turned writer.
③不能说:He got angry until his child came back home.
应改为:He didn’t get angry until his child came back home.

5.系动词能接几种表语(从句)
系动词除了接adj. .prep.短语,某些adv.以外,还可接以下几种表语形式:
①能接as if/as though表语从句的系动词有:look(看起来),smell(闻起来),sound(听起来),feel(觉得);appear(显得),seem(似乎)。例如:
It looks as if we are going to have snow.看样子天要下雪了。
He looked as if he had just stepped out of my book of fairy tales.
他看来好像刚从我的童话故事中走出来似的。
She seemed as if (though) she couldn’t understand why Laura was there.
看来她好像不能理解为什么劳拉呆在那儿。
It sounds to me as though there’s a tap running somewhere.
我好像听到某处水龙头流水的声音。
She felt as if her head were splitting.
她仿佛觉得她的头要裂开了。
The river appeared as if enveloped in smog.
那条河好像笼罩在烟雾之中。
It seems as if it were spring already.
好像已是春天了。
②可用于“It+系动词+that从句”结构的有:seem, appear, 不可用be, look。如:
It seemed that he had made some serious mistakes in his work.
好像他在工作中犯了严重错误。
It appeared that he was talking to himself.
好像他在自言自语。
③能用不定式作表语的系动词有:be, seem, get, look, appear, prove, grow.
Her job is to look after the children.
她的工作是照料孩子们。
He seems not to look after the children.
他好像不是她的父亲。
She looks to be a young girl of twenty year-old.
她看起来像是一个20岁的年轻姑娘。
He didn’t appear to dislike it.
看不出他憎恨此事。
My advice proved to be wrong.
我的建议证明是错误的。
He will grow to like this work gradually.
他会逐渐喜欢这个工作的。
④能与there连用的系动词有:be, appear, seem.
There appeared to be only one room.
那儿好像只有一个房间。
There seems(to be)no need to go.
似乎没有必要走。

6.能用两种否定形式的系动词有两个:seem, appear.
举例说明:
It doesn’t seem that we can get our money back.= It seems that we can’t get our money back.
He seems not to be her father.= He doesn’t seem to be her father.
The baby doesn’t appear to be awake.= The baby appears not to be awake.

7.后接作表语的过去分词可构成系表结构
能构成系表结构的系动词通常有两个:第一个是常见的be(is, am, was等);第二个是get,口语中常用。
当二者作系动词用时,它们均表示一种存在状态,而不表示被动动作;当二者作助动词用时,后接作谓语的过去分词构成被动语态。
Be + P.P常可以用get + P.P.来代替,但是并不是be系动词总是可以用get来代替。Get + P.P.系表结构常用于以下两种情况:
1)表示偶然的、突发性的、意想不到的被动动作的结果或状态。
Last night I got caught in the downpour.昨夜我被雨淋了(表示意想不到)
The new car got scratched.新车给刮坏了。(表突发性)
2)表示对自身所作的事。如get dressed, get lost等。
John got injured while playing football last Saturday.约翰上周星期六踢足球时受了伤。
They got married last month.他们上个月结婚了。
另外,要注意区分系表结构与被动语态结构的用法。


助动词:
协助主要动词构成谓语动词词组的词叫助动词。
助动词是语法功能词,自身没有词义,不可单独使用,只能和别的动词一起构成谓语,表示时态、语态、语气等,或表示疑问或否定。
常用的助动词有:
be,do,does,did,have,has,shall,will,would等。

常见助动词用法:
have的用法:
have作助动词
形式:
主要变化形式:have,has,had
动名词/现在分词:having
1)have +过去分词,构成完成时态,例:
He has left for London. 他已去了伦敦。
By the end of last month, they had finished half of their work.
上月末为止,他们已经完成工作的一半。
2)have + been +现在分词,构成完成进行时(现在完成时),例:
I have been studying English for ten years.我一直在学英语,已达十年之久。
3)have+been +过去分词,构成完成时态的被动语态,例:
English has been taught in China for many years.中国教英语已经多年。

do的用法:
形式
主要变化形式:do,did,done
动名词/现在分词:doing
1) 构成一般疑问句,例如:
Do you want to pass the CET?你想通过大学英语测试吗?
Did you study German? 你们学过德语吗?
2)do + not 构成否定句,例如:
I do not want to be criticized.我不想挨批评。
He doesn't like to study.他不想学习。
In the past, many students did not know the importance of English.过去,好多学生不知道英语的重要性。
3) 构成否定祈使句,例如:
Don't go there. 不要去那里。
Don't be so absent-minded. 不要这么心不在焉。
说明: 构成否定祈使句只用do,。
4)放在动词原形前,加强该动词的语气,例如:
Do come to my birthday party please.请一定来参加我的生日宴会。
I did go there. 我确实去那儿了。
I do miss you. 我确实想你。我真想你了!
5)用于倒装句,例如:
Never did I hear of such a thing.
我从未听说过这样的事情。
Only when we begin our college life do we realize the importance of English.
只有在开始大学生活时我们才认识到英语的重要性。
说明: 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。
6)用作代替动词,例如:
Do you like Beijing? 你喜欢北京吗?
Yes,I do.是的,喜欢。(do用作代动词,代替like Beijing.)
He knows how to drive a car, doesn't he?他知道如何开车,对吧?

may和can:
1) may用来表示许可
2)may用于所有人称的现在时及将来时句子中。
3)might用于所有人称的过去时及条件句中。
否定形式:may not/mayn't,might not/mightn't
疑问式:may I?might I?等
否定疑问式:may I not?/mayn't I?等
表示许可的may的其他形式可用allow,be allowed的相应形式代替。
4)may后面接不带to的不定式(即动词原形)。
5)can用来表示许可
6)can用于所有人称的现在时及将来时的句子中。
7)could用于所有人称的过去时及条件句中。
否定式:can not/can't,could not/could't
疑问式:can I?could I?等。
否定疑问式:can I not?/can't I?could I not?/couldn't I?等。
表示许可的can的其他形式可用于allow,be allowde的相应形式代替。
can与不带to的不定式连用。

shall和will的用法:
1)shall和will作为助动词可以与动词原形一起构成一般将来时,例如:
I shall study harder at English.我将更加努力地学习英语。
He will go to Shanghai. 他要去上海。
说明:
在过去的语法中,语法学家说shall用于第一人称,will 只用于第二、第三人称。
现在,尤其是在口语中,will常用于第一人称,但shall只用于第一人称,如用于第二、第三人称,就失去助动词的意义,已变为情态动词,试比较:
He shall come.他必须来。(shall有命令的意味。)
He will come.他要来。(will只与动词原形构成一般将来时。)
2)shall在疑问句中,用于第一,第三人称,征求对方意愿
shall I turn on the light?
要开灯吗?( 我把灯打开好吗?)
shall he come to see you?
他要不要来看你
(比较: will he come to see you? 他会不会来看你)
3)shall 用在陈述句,与第二第三人称连用,变为情态动词,表示允诺,命令,警告,和说话人的决心等。

should,would的用法:
1)should无词义,只是shall的过去形式,与动词原形构成过去将来时,只用于第一人称,例如:
I telephoned him yesterday to ask what I should do next week.
我昨天给他打电话,问他我下周干什么。
比较:
"What shall I do next week?" I asked.
"我下周干什么?"我问道。(可以说,shall变成直接引语时,变成了should。)
2)would也无词义,是will的过去形式,与动词原形构成过去将来时,用于第二、第三人称,例如:
He said he would come.他说他要来。
比较:
"I will go," he said. 他说:"我要去那儿。"
变成间接引语,就成了:
He said he would come.
原来的will变成would,go变成了come.。过去式从原来的go变为came。


基本助动词只有三个:
be, do,have,他们没有词汇意义,只有语法作用,如协助构成进行体,完成体,被动态,否定句,疑问句等。
例如:
He is giving a lecture. 他在作报告
He has made a plan. 他已经订了计划
The small animals are kept in the cages. 小动物都关在笼子里。
助动词协助主要动词完成以下功用:
a. 表示时态,例如:
He is singing. 他在唱歌。
He has got married. 他已结婚。
b. 表示语态,例如:
He was sent to England. 他被派往英国。
c. 构成疑问句,例如:
Do you like college life? 你喜欢大学生活吗?
Did you study English before you came here? 你来这儿之前学过英语吗?
d. 与否定副词not合用,构成否定句,例如:
I don't like him. 我不喜欢他。
e. 加强语气,例如:
Do come to the party tomorrow evening. 明天晚上一定来参加晚会。
He did know that. 他的确知道那件事。
动词不定式:
指由to加上动词原形(而且只能是动词原形)所构成的一种非限定性动词,但在有些情况下to可以省略。
动词不定式在语法功能上可作主语、宾语、宾语补足语、表语、定语和状语。
动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性。
动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出。
这一使动者我们称之为逻辑主语,其形式如下:
时态 主动形式  被动形式 
一般式 (not) to do (not) to be done
完成式 (not) to have done (not) to have been done
进行式 (not) to be doing  
完成进行式 (not) to have been doing  

不定式的用法:
1、不定式作主语
例如:To remember this is very important.
注意:为了避免头重脚轻,在许多情况下,通常都将作主语的不定式置于句子后部,而在句首主语位置使用形式主语it。
例如:It is very important to remember this.
2、不定式作表语
例如:He seems to be ill.
注意:不定式作表语主要有三种情况,一是用于seem, appear, prove等系动词之后的不 定式(尤其是to be),
二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形,
三是表示想法、约定、义务、命令、可能性、命运等,如: 
You are to come when I call.
3、不定式作宾语
例如:I can not afford to buy a car.
注意:
①不定式不仅用作动词的宾语,还可用作个别介词(but, except)的宾语。
例如:I had no choice but to wait.
②当作宾语的不定式后跟有宾语补足语时,通常要用形式宾语it代替不定式,并将真正的宾语不定式置于宾语补足语之后
例如:I find it difficult to learn Japanese well.
4、不定式作宾语补足语
例如:Who taught you to drive?
5、不定式作定语
例如:I have a question to ask you.
注意:有的名词(如way, chance, right等)后用作不定式可换成of doing sth.
如:It is the best way to do (of doing) it.
但是以下名词后接不定式作定语时通常不能换成of doing sth.
attempt  courage  decision  effort  fortune  failure  invitation  wish
6、不定式作状语
例如:I went to France to learn French.
分词:
就是具有动词及形容词二者特征的词;尤指以-ing或-ed,-d,-t,-en或-n结尾的英语动词性形容词,具有形容词功能,同时又表现各种动词性特点,
如时态,语态、带状语性修饰语的性能及带宾语的性能。
分词分为现在分词和过去分词两种,是一种非谓语动词形式。
现在分词和过去分词主要差别在于:
现在分词表示"主动和进行",过去分词表示"被动和完成"(不及物动词的过去分词不表示被动,只表示完成)。
分词可以有自己的状语、宾语或逻辑主语等。

现在分词构成形式:
①一般在动词原形末尾加ing,如do→doing、sing→singing、comfort→comforting
②以不发音的e、ue结尾的动词,先去e,再加ing,如dance→dancing、hike→hiking、write→writing、make→ making,take→taking
③以ee、oe、ye结尾的动词加ing,如see→seeing、toe→toeing、dye→dyeing
④以重读闭音节结尾的动词,并且末尾只有一个辅音字母,应双写这一字母,再加ing,如cut→cutting、swim→swimming
注:结尾是x则不必双写,如relax→relaxing
⑤以ie结尾的动词,要把ie变成y再加ing,如die→dying,lie→lying.
⑥以ic结尾的动词,要把ic变成ick再加ing,如picnic→picnicking,traffic→trafficking

过去分词构成形式:
1.规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则:
(1)、一般动词,在词尾直接加“ ed ”。(然而要注意的是,过去分词并不是过去式)
work---worked---worked ,  visit---visited---visited
(2)、以不发音的“ e ” 结尾的动词,只在词尾加“ d ”。
live---lived---lived
(3)、以“辅音字母 + y ”结尾的动词,将 "y" 变为 "i" ,再加“ ed ”。
study---studied---studied,cry---cried---cried,try---tried---tried,fry---fried---fried.[1]
(4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”。
stop---stopped---stopped  ,  drop---dropped--dropped
(5)、以ic结尾的动词,要把ic变成ick再加ed,
picnic→picnicked  ,traffic→trafficked
2 、不规则动词:见不规则动词表


分词用法:
1、分词作状语   
分词在句子中作状语,可以表示时间、条件、原因、结果、让步、伴随等。   
分词(短语)作状语时,其逻辑主语应与句中主语相一致。
当现在分词表示的动作发 生在谓语动词之前时, 则用现在分词的完成式,且所表示动作与谓语动作同时发生, 则用现在分词的一般式。
完成或被动关系用过去分词。   
①现在分词:
The students went out of the classroom, laughing and talking.   
②过去分词:
Accompanied by his friend, he went to the railway station. 
Given   better attention, the plants could grow better.   

2、“while ( when, once, until, if , though等连词)+分词”结构   
现在分词或过去分词作状语时,有时可以在分词前加while,when, once, although, until, if等连词。   
①现在分词:
When leaving the airport, she waved again and again to us.
While waiting for  the train, I had a long talk with my sister about her work……   
②过去分词:
Once recovered, he threw himself into his work and made every effort to do it  well.   
Although working very hard, he failed to pass the final exam. If translated word by word, the passage will be difficult to understand.   

3、分词作定语   
分词作定语时,单个的分词通常放在被修饰的名词之前,分词短语一般置于所修饰的中心词后面。
现在分词修饰的是发出该动作的名词(即与名词有主谓关系),过去分词修饰承受该动作的名词(即与名词是动宾关系)。    
We will go on with our experiment as soon as we get the added fund.    
This is really an exhausting day to all of us!   
We can see the part of the moon lighted by sunlight.   
After a night spent in excitement and sleeplessness, I forced myself to take a long walk along the beach the next day.   
More and more developing countries established strategic partnership with  developed countries   

4、分词作宾语补足语   
现在分词在see, watch, hear, observe, notice, feel, find, glimpse, glance等感官动词和look at, listen to等短语动词以及
have, keep, get, catch, leave, set, start, send等使役动词后面与名词或代词构成复合宾语,作宾语补语的成分。
例:I see him passing my house every day.
I caught him stealing things in that shop.
I smelt something burning.

5、分词作表语
分词作表语通常看作形容词来用。
过去分词表示主语的感受或状态,主语多为人。现在分词表示主语的性质,而且主语多为物;
①过去分词:
We were so bored that we couldn’t help yawning.
She felt confused, and even frightened.
②现在分词:
He was very amusing.
That book was rather boring.
很多动词的现在分词都可以作表语:
exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.


动名词:
如果一个动词加上了ing变成了名词,那么这个词称动名词。 动名词是一种兼有动词和名词特征的非限定动词。
它可以支配宾语,也能被副词修饰。
由于动名词是由动词变化而来,它仍保留着动词的某些特征,具有动词的某些变化形式,用以表达名词所不能表达的较为复杂的意念。
动名词的名词特征表现在它可在句子中当名词来用,作主语、宾语、表语、定语。

动名词的结构和形式:
动名词的否定结构:
动名词的否定结构由not 动名词组成。如:
Trying without success is better than not trying at all. 实验没有成功也比不实验好。
He hated himself for not having work hard. 他悔恨自己没有用功。
I’m sorry for not having telephoned you before. 很抱歉,没有早给你打电话。
He felt sorry for not having done the work well. 他为没有把工作做好感到难过。
I fancy it has done you a lot of good not going. 我看不去对你倒好了。
(not going 是动名词一般式的否定形式)
There is no denying the fact that he si diligent.
(no denying 也是动名词一般式的否定)

动名词复合结构:
通常情况下,动名词的逻辑主语为谓语动词的主语。如果动名词动作的发出者不失谓语动的主语时,则需要有自己的逻辑主语物主代词或名词所有格加动名词就构成了动名词的复合结构,这种结构在句中可以作主语,宾语等。
(1)逻辑主语是有生命的名词作主语时,必须用名词或代词所有格,作宾语时(尤其在口语中),也可用名词普通个或人称代词宾格。如:
Do you think my going there will be of any help?
你看我去会有什么帮助吗?(宾语)
The student’s knowing English well helps him in learning French.
这位学生通晓英语对他学法语很有帮助。(主语)
Do you mind my(me) smoking ? 你介意我抽烟吗?(宾语)
They insist on Mary’s (Mary) going with them there.
他们坚持要玛丽跟他们一起去那儿。(介词宾语)
(2)逻辑主语是无生命名词是,通常只用名词普通格。如:
Do you hear the rain pattering on the roof?
你听见雨点打在屋顶上了吗?
Is there any hope of our team winning the match ?
我们对赢得比赛有希望吗?
(3) 逻辑主语是指示代词或不定代词this that , somebody , someone , nobody, none, anybody, anyone 时,只用普通格。如:
She was woken up by somebody shouting outside.
她被外面喊叫的人吵醒了。

动名词的形式(一般式,完成式和被动式):
(1) 动名词的一般式所表示的动作与谓语动词所表示的动作同时发生,或在谓语动词表示的动作之后。如:
We are very interested in collecting stamps. 我们对集邮很感兴趣。
His coming will be of great help to us . 他来对我们大有帮助。
但是有些明确表示时间的动词和介词 after, on,upon, 或for之后,常用一般式代替完成式,表示动作发生在谓语动作之前。如:
I shall never forget seeing the Great Wall for the first time.我永远不会忘记第一次看到长城的情景。
On hearing that bad news , the mother couldn’t help crying. 一听到这个糟糕的消息,母亲就禁不住哭了起来。
Excuse me for coming late. 我来晚了,请原谅。
Thank you for giving us so much help. 谢谢你给了我们这么多帮助。
(2) 动名词的完成式所表示的动作或状态在谓语动词之前完成或结束。
He regrets not having taken part in the work. 他后悔没有参加这项工作。
We were praised for having finished the work ahead of time. 我们因提前完成了这项工作而受到了表扬。
(3)动名词的被动式:当动名词的逻辑主语是行为承受者时,用被动语态。如:
I like being given harder work. 我喜欢接受难点的工作。
She is proud of being admitted into the university. 她为被大学录取而感到自豪。
The meeting was put off without his having been consulted. 会议延期并未和他商量。
He doesn’t mind having been criticized. 他不介意过去受到的批评。


动名词与现在分词的关系:
动名词它在形式上与现在分词相同,都是在动词原形的词末加-ing。在现代语法中,这两种形式同视为"-ing形式"。
这两种形式的另一个相同之处是:
它们都是由动词变化而成的,它们都保留了动词的某些特征,它们都能带自己的宾语、状语,而构成动名词短语或是现在分词短语去担当句子成分。
例如:
Speaking in the public,he will surely be very cheerful .
(现在分词短语,作状语)他在公众场所讲话时总是兴高采烈的。
She hates speaking in the public.
(动名词短语,作宾语)她不喜欢在公众场所讲话。

动名词和现在分词都可以用于系动词之后作表语,区别方法是:
①作表语的动名词与主语指的是同一件事,此时系动词相当于“是”,通常把主语和表语的位置互换,语法和意思不变,例如:
My hobby is swimming.可改为Swimming is my hobby.(可将原句中的主语与表语位置互换)
②现在分词作表语主要用以说明主语的性质,不能与主语互换位置,例如:
The story is interesting .不可改为:Interesting is the story.
2.动名词和现在分词都可以用作定语来修饰名词,两者的区别在于:
动名词修饰名词时主要表示该名词的用途,而现在分词修饰名词时性质、状态或动作等。试比较:
①a swimming boy和a swimming suit
前者的意思是“一个正在游泳的男孩”,即a boy who is swimming,现在分词swimming 表示被修饰名词boy的动作;
而后者的意思是“游泳衣”,即a suit for swimming,动名词swimming表示suit 的用途。
②a sleeping child 和 a sleeping car
前者的意思是“一个正在睡觉的孩子”,即a child who is sleeping,现在分词sleeping 表示被修饰名词 child 正处于的状态;
而后者的意思是“卧车(被用来睡觉的车厢)”,即 a car which is used for sleeping,动名词 sleeping 表示car 的用途。


动名词用法口诀:
动名词常泛指,句法作用宾/表/定与主,时态/语态之形式,一般/完成/被动式。
Being done 系被动,不含任何进行意。用作主语请留意,常用it作形式主语,不指未来发生事,表达的信息系已知。
用作表语请记清,作用相当一名词,检验方法很简单,主与表换位能成立。
用作定语也易辩,表示名词之用途。
用作宾语稍复杂,关键留意谓语动词(跟动名词作宾语的常用动词附后),时态同谓动作比较,先于谓动用完成式,其逻辑主语不固定,在句中/句外均有之。
否定式其前加not,复合式其前加物主词,非句首宾格词也可用,尤其口语中更如此。
说明:1、主-----主语 2、宾-----宾语 3、表------表语 4、定------定语 5、谓动---谓语动词

动名词的用法:
一、动名词作主语 
1. 直接位于句首做主语。例如:   
     Swimming is a good sport in summer.   
2. 用 it 作形式主语,把动名词(真实主语)置于句尾作后置主语。   
动名词做主语时,不太常用 it 作先行主语,多见于某些形容词及名词之后。例如:
It is no use telling him not to worry.   
常见的能用于这种结构的形容词还有:better,wonderful,enjoyable,interesting,foolish,difficult,useless,senseless,worthwhile,等。   
注意:important,essential,necessary 等形容词不能用于上述结构。   
3. 用于“There be”结构中。例如:   
There is no saying when he'll come.很难说他何时回来。    
4. 用于布告形式的省略结构中。例如:   
No smoking ( =No smoking is allowed (here) ). (禁止吸烟)   
No parking. (禁止停车)   
5. 动名词的复合结构作主语   
当动名词有自己的逻辑主语时,常可以在前面加上一个名词或代词的所有格,构成动名词的复合结构
(这时,名词或代词的所有格做动名词的逻辑主语)。
动名词的复合结构也可以在句中作主语。例如:    
Their coming to help was a great encouragement to us.   

二、动名词作宾语
1.作动词的宾语   
某些动词后出现非限定性动词时只能用动名词作宾语,不能用不定式。常见的此类动词有:
admit, appreciate, excuse, stand, advise, allow, permit, avoid,  consider, enjoy, finish     
They went on walking and never stopped talking.他们继续走,说个不停。 
I found it pleasant walking along the seashore.在海滩上走真是乐事。   
Mark often attempts to escape being fined whenever he breaks traffic  regulations.   
每当马克违反交通规则时,他常常企图逃避罚款的处分。    
2.作介词的宾语   
We are thinking of making a new plan for the next term. 我们正考虑为下学期制定新的计划。   
Shall we have a rest or get down to doing our work? 我们休息呢还是开始干活?   
3.作形容词的宾语   
The music is well worth listening to more than once.  这种曲子很值得多听几遍。   
We are busy preparing for the coming sports meet. 我们正为马上到来的运动会忙着做准备。

三、动名词作表语
动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。
表语、动名词与主语通常是对等的关系,表示主语的内容,主语、表语可互换位置。   
Your task is cleaning the windows.   你的任务就是擦窗户。
(Cleaning the windows is your task.)   
What I hate most is being laughed at.  我最痛恨的就是被别人嘲笑。
(Being laughed at is what I hate most.)

四、动名词作定语
动名词作定语往往表示被修饰词的某种用途。如:   
a walking stick =a stick for walking=a stick which is used for walking   
a washing machine=a machine for washing=a machine which is used for washing    
a reading room=a room for reading=a room which is used for reading   
a measuring tape=a tape for measuring=a tape which is used for measuring   
sleeping pills=pills for sleeping=pills which is used for sleeping


动名词是非限定动词的一种形式,由动词原形+ing构成。它既有动词的特征,又有名词的特征,故称。
动名词也有时态和语态的变化,如表所示(以及物动词write为例),不及物动词没有语态的变化。
时态、语态 主动 被动
一般式 writing being  written
完成式
having written
having been written

动名词使用注意事项:
1) 动名词做主语时,谓语动词为单数
2) 在动名词和不定式中,作为介词的宾语是动名词
3) 动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语
例:I would appreciate you calling back this afternoon.
4) 有些词后只能接动名词
acknowledge;admit; advise;advocate;allow;appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny;
detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can’t help;
hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent;
recall; report; resent; resist; risk; suggest; understand...
5) 另外还有一些接-ing形式的常用说法
it’s no good; it’s no/little/hardly any/ use; it’s not/hardly/scarcely use; it’s worthwhile; spend money/time; there’s no;
there’s no point in; there’s nothing worse than; what’s the use/point
6) 有些词后面加不定式和动名词均可
remember,forget,try,stop,go on,continue,stop,regret,cease,mean后面均可用不定式和-ing形式,但意义截然不容。
例:remember to do/doing:
①I remembered to post the letters.(指未来/过去未来将要做的动作)
②I remembered posting/having posted the letters.(我记得做过这个动作)
 forget与remember的用法类似。
 regret的用法:
①I regret to inform you that…(我很遗憾地通知你……)
②I regretted having left the firm after twenty years.(为了“二十年前的离开”而遗憾。)
 try to(努力)与try +–ing(试验):
①You really must try to overcome your shyness.
②Try practicing five hours a day.
一般过去时:
表示过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为;过去主语所具备的能力和性格。
基本结构:
主语+动词过去式+其他;
否定形式①was/were+not;②在行为动词前加didn't,同时还原行为动词;
一般疑问句Did+主语+do+其他。
一般过去时句法结构:
肯定形式
主语+动词过去式+其他
例句:She often came to help us in those days.
否定形式
①was/were+not;②在行为动词前加didn't,同时还原行为动词
例句:I didn't know you like coffee
一般疑问句
①Did+主语+do+其他? ②WasWere+主语+表语?
例句:Did I do that?
用表格整理如下:
肯定式 疑问式 否定式 疑问否定式
Iworked Did I work? I did not work Did I not work?
He(She,It) worked Did he(she,it) work? He(she,it) did not work Did he(she,it) notwork?
We worked Did we work? We did not work Did we not work?
You worked Did you work? You did not work Did you not work?
They worked Did they work? They did not work Did they not work?
记忆口诀:
一般过去时并不难,过去动作、状态记心间。
动词要用过去式,时间状语句末站。
否定句很简单,didn't 站在动原前,其它部分不要变。
一般疑问句也好变,did放在句子前,主语、动原、其它部分依次站。
特殊疑问句也简单,疑问词加一般疑问句记心间。
最后一条请注意,动词过去式要牢记!

Was there an apple on the table last night
一般过去时注意事项:
1.注意主句与从句中时态的一致性
如果主句用了过去时,从句中一般也要用过去式,或者过去进行时、过去完成时等。例如:
He believed that he was right. 他相信自己是对的。
I didn’t know you were here. 我不知道你在这儿。
I thought they were with you. 我以为他们和你在一起。

2.在口语中, 一般过去时并不一定指真正的过去,而只是表示一种礼貌性语气。例如:
I wondered (wonder) if you could do me a favor. 不知你可否帮我一个忙。
I wanted (want) to ask if I could borrow your car. 我想问问可否借用你的车。
I hoped (hope) you could (can) give me some advice. 我希望你能帮我出点主意。
Did (Do) you want to see me? 你想见我吗?

3.used to
used to 是一个词组,表示“过去曾经是……而现在已经停止了”的动作。例如:
I used to work fourteen hours a day. 我过去常常一天干十四个小时。(而现在不这样了)
I used to take a walk in the morning.我过去是在早晨散步。(而现在不在早晨散步了)
一般过去式用法:
(1)一般过去时表示在过去某个特定时间发生,也可以表示过去习惯性、经常性的动作。
一般过去时不强调动作对现在的影响,只说明过去的事情。
句式:主语+动词过去式+宾语+其它
I had a word with Julia this morning.今天早晨,我跟茱莉雅说了几句话。
He smoked many cigarettes a day until he gave up. 他没有戒烟的那阵子,抽烟抽得可凶了。

(2) 一般过去时常与表示过去的时间状语或从句连用,如:
yesterday,last week ,in  the  past ,in 1993,at that time,once,during the war,before,a few days ago,when 等等.
(句子中谓语动词是用一般过去时还是用现在完成时,取决于动作是否对现在有影响)。
Have you had your lunch? 你吃过午饭了吗?(你现在不饿吗?)
Yes,I have. 是的,我已经吃过了。(已经吃饱了,不想再吃了。)
When did you have it? 你是什么时候吃的?(关心的是吃的动作发生在何时。)
I had it about ten minutes ago. 我大约是十分钟以前吃的。)
Used to do something 表示过去常做而现在已经停止了的习惯动作。
I used to work fourteen hours a day. 我过去常常一天干十四个小时。
I ate it at 6:45。我在六点四十五分吃了。

(3)带有确定的过去时间状语时,要用过去时。如:
yesterday(昨天)、two days ago…(两天前…… )、last year…(去年…)、the other day(前几天)、
once upon a time(很久以前)、 just now(刚才)、in the old days(过去的日子里)、before liberation(解放前…)、
When I was 8 years old(当我八岁时…)、at+一个时间点
Did you have a party the other day?前几天,你们开了晚会了吗?
Lei Feng was a good soldier.雷锋是个好战士。
注:在谈到已死去的人的情况时,多用过去时。

(4)表示过去连续发生的动作时,要用过去时。这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。
The boy opened his eyes for a moment,looked at the captain,and then died.
那男孩把眼睛张开了一会儿,看看船长,然后就去世了。

(5)表示过去一段时间内经常或反复的动作。常与always,never等连用。
Mrs. Peter always carried an umbrella.彼得太太过去老是带着一把伞。
(只是说明她过去的动作,不表明她现在是否常带着伞。)
比较:
Mrs. Peter always carries an umbrella.彼得太太老是带着伞。
(说明这是她的习惯,表明她现在仍然还习惯总带着一把伞)
Mrs. Peter is always carrying an umbrella.彼得太太 总是带着一把伞。
(表示说话者对这一动作或行为厌烦)
I never drank wine.我以前从不喝酒。
(不涉及到现在,不说明现在是否喝酒)

(6)如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了)
He used to drink alcohol.他过去喝酒。
(意味着他现在不喝酒了。喝酒这个动作终止了)
I used to take a walk in the morning.我过去是在早晨散步。
(意味着现在不在早晨散步了)
比较:
I took a walk in the morning.我曾经在早晨散过步。
(只是说明过去这一动作)

(7)有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时。
I didn''t know you were in Paris.我不知道你在巴黎。
(因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)
I thought you were ill.我以为你病了呢。
(这句话应是在说话之前,我以为你病了。但是现在我知道你没病)
一般过去时三变技巧:
一变:肯定句变为否定句
技巧1.当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如:
I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
技巧2.当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如:
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如:
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.

二变:陈述句变为一般疑问句
技巧1.移动词语的位置。将was,were, could,would,should等移到句首。例如:
He could pack his things himself. → Could he pack his things himself?
技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时,在主语之前加did,动词还原。例如:
Mr Li looked very old. → Did Mr Li look very old?

三变:陈述句变为特殊疑问句
技巧1.确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如:
They gave the concert last night. → When did they give the concert?
技巧2.辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如:
The accident happened near the station. → Where did the accident happen?
现在进行时:
表示现在或当前一段时间正在进行的动作。可以表示有计划的未来,也就是用现在进行时表示将来。
现在进行时的构成是:
主语+be+v.ing〔现在分词〕形式
例如:He is writing on the desk.

现在进行时的构成:
主语+be+v.ing〔现在分词〕形式
第一人称单数I+am+ing.
第一人称复数We+are+ing.
第二人称单(复)数 You+are+ing
第三人称单数 He(She,it)+is+ing
第三人称复数 They+are+ing
肯定句:主语+be(is/am/are)+现在分词
否定句:主语+be(is/am/are)+not+现在分词
一般疑问句:be(is/am/are)+主语+现在分词
特殊疑问句:特殊疑问词+相应be动词+主语+现在分词+Sth?
间接引语中改为过去进行时。

变化规则:
1.直接+ ing(例:sleep+ing 变sleeping)
2.去掉不发音的e+ing(例:bite-e+ing 变biting)
3.重读闭音节,以辅音字母加元音字母加辅音字母结尾的词,要双写尾字母再加ing(例:swim+m+ing=swimming)
4.以ie结尾的重读闭音节,变ie为y+ing (例:die-dying lie-lying)
5结尾为c且c读作/k/时,在结尾加k再加ing,如picnic-picnicking


现在进行时与一般现在时的区别:
(一)现在进行时表示动作的暂时性,而一般现在时表示动作的习惯性和经常性
I am watching TV now. (暂时性)
I watch TV every day. (经常性)
(二)现在进行时可表示短暂性动作,而一般现在时表示长久性动作。
Lucy is living in Beijing.(短时间居住)
Lucy lives in Beijing. (长久性居住)
(三)现在进行时表示的动作可带有感情色彩,而一般现在时所表述的动作通常是事实。
You’re always forgetting the most important things. (责备)
He is always helping others. (赞扬)
He often helps others. (事实)
(四)有些动词不能用进行时,know, understand, love, like, hate, wish, want, think, hope, have, believe, agree, hear, see, notice,等等。
这些动词通常用一般现在时表示说话时发生的动作。
I have a lot of friends here.
She wants to buy a new bike.

现在进行时用法注意:
1.进行时中,并不是所有的动词都要使用正在进行时。
例如一些表示状态和感觉的动词,一般不用进行时态,而是用现在一般时表示。
这些动词往往是等表示情感状态、知觉认识、愿望或短暂性的动词。
例如:see(明白),know, want, like, hear, have(有), think, hope, hate等。
I hear someone singing. 我正听见有人唱歌。
Do you see anyone over there? 你看到那里有什么人吗?
What does he think of it? 他觉得这怎么样?
如果这些词使用正在进行时态,句子带有某种感情色彩。例如:
Are you seeing someone off? 你在给谁送行吗?
They are hearing an English talk. 他们在听一个英语报告。

2.现在进行时还有另外一种含义,即它们能表达即将发生的事情,相当于一般将来时。
有些动词从结构来看是现在进行时,但却是表示将要发生的事,而不表示动作现在正在进行。
这些动词往往是一些表示位置移动变化的动词:arrive, come, do, get, go, have, leave, meet, play, return, see, spend, start, stay, wear, work等。
We are leaving on Friday。我们星期五出发。
Are you going anywhere tomorrow?你明天准备去哪儿?
A foreign guest is giving a lecture this afternoon。今天下午一个外国客人将给我们作报告。
Are you staying here till next week? 你打算在这里呆到下个星期吗?
在表示将来的情况下,特别是be going to do sth. 这种结构,已经没有多少“去”的意思了,几乎就是用来表达“将要、打算”做什么事情。例如:
It is going to be rather cold tomorrow。明天很可能非常冷。
She is not going to speak at the meeting。她不打算在那个会上发言。

3.当其与always、forever、continually、constantly 等副词连用时表示重复的动作,而这种动作可能使人不满,厌倦或满意。例如:
①She is perpetually interfering in my affairs.她老是干预我的事。 (不满)
②The students are making progress constantly.学生们在不断进步。 (满意)

4.在时间、条件状语从句中,有时可用现在进行时代替一般将来时。
When you are passing my way,please drop in.
你什么时候路过我家,请进来坐。


现在进行时的用法:
A表示现在( 指说话人说话时) 正在发生的事情。
例:We are waiting for you.
B. 表示现阶段正在进行的动作,说话时未必正在进行。
例:Mr. Green is writing another novel.
(说话时并未在写,只处于写作的状态。)
例:She is learning piano under Mr. Smith.
C.已经确定或安排好的但不确定会不会发生的将来活动。
I'm leaving for a trek in Nepal next week.(我下周要去尼泊尔旅行)
We're flying to Paris tomorrow.(我们明天乘飞机去巴黎)现在进行时的应用
D .些非持续性动词的进行时可以表示动作即将进行或发生,或表示动作的重复。
   例如:He is joining the army.
E.当现在进行时中有always, forever, constantly, continually修饰时,表示说话人的
   赞赏或厌烦的情绪。
   例如:They are always helping us.
注意:表示状态、感觉、心理活动的静态动词时,一般不使用进行时态。
F.子中有now时,常表示动作正在进行,这时要用现在进行时。如:
They are playing basketball now.现在他们正在打篮球。
G.ook, listen开头的句子,提示我们动作正进行,这时要用现在进行时。如:
Listen!She is singing an English song.听,她正在唱英语歌。
H.当前一段时间或现阶段正在进行的动作,且此时有this week, these days等时间状语,这时常用现在进行时。如:
We are making model planes these days.这些天我们在做飞机模型。
I.图片中的人物的动作,也为了表达更生动。此时也常用现在进行时。如:
Look at the picture. The children are flying kites in the park.看这幅图,那些孩子正在公园放风筝。

一般将来时:
表示将来某一时刻的发生动作或状态,或将来某一段时间内经常的动作或状态。
一般句型有:

否定句:

疑问句:
Shall I/we go? Will you/he/she/they go?
简略回答:
(肯)Yes,主语shall/will (否) No,主语 shall/will not
特殊疑问句:
一般将来时的特殊疑问句是将疑问词放在句首,后接一般疑问句(就主语提问时,以疑问词who开头的疑问词除外)
Why will you be here on Sunday?(周日你为什么将要在这儿?)
I will have a meeting on Sunday(我将要在周日举行一个聚会)
(对特殊疑问句要进行具体回答)
一般疑问句:
be或will提到句首,some改any,and改or,第一二人称互换

Are you going to go on an outing this weekend?
被动句:
will/shall+be+v.ed(及物动词过去分词)
The letter will be sent tomorrow.
这封信明天将寄出去
We shall be punished if we break the rule.
如果我们违反规定,我们将受到惩罚。


一般将来时的构成:
1. 用will或shall表示   
“助动词will或shall+动词原形”这一形式,表示将来发生的事情,用于征求对方的意见或表示客气的邀请。在口语中will用于所有人称,书面语中第一人称常用shall,如:   
①Tomorrow will be Sunday. 明天就是星期天。    
②The rain will stop soon. 雨很快就要停了。    
③Shall we go there at five? 我们五点钟去那儿,好吗?   
④Will you please open the door? 请你把门打开,好吗?   
2. 用be going to结构表示    
“be going to+动词原形”用来表示近期或事先考虑过的将要发生的动作以及已有迹象 表明必将发生某事,意为“打算;就要”。如:    
①We’re going to meet outside the school gate. 我们打算在校门口见面。    
②Look! It's going to rain. 瞧!快下雨了。   
3. 用现在进行时表示   
表示位置转移的动词(如:go, come, leave, start, arrive等),可用现在进行时表示将来时。如:   
①Uncle Wang is coming. 王叔叔就要来了。   
②They’re leaving for Beijing. 他们即将前往北京。   
4. 用一般现在时表示   
根据规定或时间表预计要发生的动作,在时间和条件状语从句中,都可用一般现在时表示将来时。如:   
①The new term starts (begins) on August 29th. 新学期八月二十九日开学。    
②If it doesn’t rain tomorrow, we will go out for a picnic.
如果明天不下雨,我们将出去野餐。   
5. 用“be+动词不定式”或用“be about to +动词原形”的结构表示,如:   
①He is to visit Japan next year. 明年他将访问日本。    
②They’re about to leave. (=They’re leaving.) 他们就要走了。

be going to与will的区别:
be going to与will两者都可表示将要发生的事、将要去做某事,但它们有如下几点区别:
1. be going to 表示近期、将要发生的事情,will 表示的将来的时间则较远一些,如:
He is going to write a letter tonight.
He will write a book one day.
2. be going to 表示根据主观判断将来肯定发生的事情,will表示客观上将来势必发生的事情。
He is seriously ill. He is going to die.
He will be twenty years old.
3. be going to 含有“计划,准备”的意思,而 will 则没有这个意思,如:
She is going to lend us her book.
He will be here in half an hour.
4.在有条件从句的主句中,一般不用 be going to, 而多用will, 如:
If any beasts comes at you, I'll stay with you and help you

shall和will区别:
1.shall和will常常缩写成'll,紧接在主语之后。其否定式 shall not 和will not 的缩写式分别为 shan't 和 won't。
基本句型:
be to表示客观安排或受人指示而做某事。后+动词原形。
be about to+动词原形,意为马上作某事,不能与tomorrow,next week等表示明确将来时的时间状语连用。
2.will和shall在句子中所表达的“意志”是不同的,当句子主语是第一人称(I)的时候表示的是主语 I 的自主“意志”。
例:I will be clear tomorrow . 我会把这件事弄个水落石出
分析:这个句子中用will时,主语 I(我) 就带有强烈的意志,意思是我想让事情水落石出,并且有我会为此付诸努力的意思。
3.当第一人称,用shall的时候就是一个普通的句子,就没有主语的意志。
I shall come back in ten minutes .这句话就是单纯的说 我会在10分钟后回来 没有别的意思
I will come back in ten minutes. 而这句话就有一种意境上的不同。
我会在10分钟后回来,其中的意思还有,就算我有事耽搁了我也会想办法在10分钟后回来的意思
4.shall在第二 、三人称时也和will在第一人称一样。也只有在二三人称才带有意志,只不过shall带有的是“说话者”的意志。而不是主语的意志。
如:he shall be rewarded. 他会得到回报
分析这句话更深度的意思,我说过在shall用在第二三人称时有强烈的“说话者”的意志。
而这句话的“说话者”意志就是 他会得到回报,就算他没有得到回报“说话者”也会想办法让“he”得到回报。


一般现在时的用法:
基本用法:

例如:I will(shall) arrive tomorrow.我明天到。(主语是第一人称时最好用shall)

We won’t (shan’t) be busy this evening. 我们今晚不忙。
(2)在一般将来时的句子中,有时有表示将来时间的状语,有时没有时间状语,这时要从意思上判断是否指未来的动作或情况。
例如:Will she come? 她(会)来吗?
(3)在以第一人称I或we作主语的问句中,一般使用助动词shall,这时或是征求对方的意见(a),或是询问一个情况(b):
a. Where shall we meet? 我们在哪儿碰头?
b. Shall we have any classes tomorrow?明天我们有课吗?
在这类问句中,近几年来也有不少人用will,特别是在美国。例如:

英语中的一致主要包括主语和谓语在人称和数上的一致、时态一致、名词和其代词的一致。
主语和谓语保持一致叫主谓一致,即谓语动词的形式必须随着主语单、复数形式的变化而变化。
主谓一致原则:
1、语法上的一致
所谓语法一致原则,即主语和谓语的语法形式在人称和数上取得一致。
谓语的单、复数形式依据主语的单、复数形式而定:主语为复数,谓语动词用复数;主语为单数或者是不可数名词,谓语动词用单数。
China belongs to the Third World. 中国属于第三世界。

使用语法一致的情况

"表里不一"现象:
主谓一致中的"表里不一"现象
和主语必须在人称和数上保持一致,最基本的原则是:单数主语用单数动词,复数主语用复数动词.但在实际使用当中情况比较复杂,现在学生常犯的主谓一致错误归纳整理如下
1,"more than one +名词"作主语时,谓语动词常用单数.例如:
More than one teacher gets the flowers. 不止一个教师得到了花.
2,"many a +名词"作主语时,从意义上看是复数,但谓语动词常用单数.例如:
Many a student has been sent to plant trees. 很多学生被派去植树.

4,all指人时,动词用复数;all指物时,动词用单数.例如:
"All are present and all is going well." 所有人全部到场了,一切进展顺利
5,what引导的主语从句,谓语动词可视表语而定:表语是单数名词时,动词用单数,相反,则用复数.例如:
What they want to get are a number of good books.他们想得到的是大量的好书.
6,and连接的两个单数名词前若用each,every,no修饰,该名词短语作主语时,谓语动词用单数形式.例如:

7,当主语后面有as well as,with,along with,together with,but,like,rather than,except,逗号加and连接几个名字等引导的短语时,谓语动词要与最前面的主语保持一致.例如:
My father as well as his workmates has been to Beijing. 我父亲和他的同事曾去过北京.
8,each作主语的同位语时,谓语动词由主语来决定,与each无关.例如:
They each have a bike. 他们每人有一辆自行车.
9,动词不定式,动词-ing形式短语作主语时,谓语动词常用单数.例如:
Going out for a walk after supper is a good habit.晚饭后出去散步是一个好习惯.
10,the following作主语时,谓语动词的数与后面名词的数保持一致.例如:
The following are good examples下面是一些好例子.

Politics is now taught in all schools. 现在各学校都开设政治课.
当以-ics结尾的学科名词表示"学科"以外的意义时,用作复数,如:mathematics(运算能力)politics(政治观点)economics(经济意义)等
12,有些用来表示由两个对应部分组成一体的名词复数(trousers,glasses,shoes.shorts.scissors.scales等)作主语时,前面若有"一条","一副","一把"之类的单位词,动词用单数;若没有单位词或单位词是复数,则谓语动词用复数.例如:
The shoes are all right. 这些鞋子都很合适.
还有一些以-s结尾的名词通常用复数:arms(武器).clothes.contents.minites(记录).remains(遗体).thanks等
13,"one and a half +名词"作主语时,谓语动词要用复数.例如:

14,"One or two more +复数名词"作主语时,谓语动词用复数.例如:
One or two persons are sent there to help them do the work. 要派一两个人到那儿去给他们帮忙.

以-s结尾的名词作主语的主谓一致:
英语可数名词的规则复数形式是在词尾加-s或-es,但是有一些以-s结尾的名词并不是可数名词。
它们用法多样,造成了实际使用上的困难,以下详述了以-s结尾的名词作主语的主谓一致问题。
(一)以-s结尾的疾病名称作主语的主谓一致问题
(二)以-s结尾的游戏名称作主语的主谓一致问题
(三)以-s结尾的地理名称作主语的主谓一致问题
(四)以-ics结尾的学科名称作主语的主谓一致问题
(五)其它以-s结尾的名词的主谓一致问题

集合名词的主谓一致原则:

集合名词作主语时,主谓一致关系是一个较为复杂的问题.对此类问题我们可以从"数"的角度分为四类.
1)单数—复数型.凡是有复数词尾变化形式的集合名词都属于此类。如:
a class—classes; a family—families; a government—governments; an army—armies; a people—peoples; a group—groups; a crowd—crowds; a crew—crews等。
这类集合名词强调的是整体性,即当作一个整体或多个整体来看待。属于这类集合名词的单数作主语时,谓语动词用单数;
复数形式作主语时,谓语动词用复数。
【例如】
A big crowd often gathers on the square every morning.
每个上午 一大群人经常聚集在广场上
The government has decided to pass the bill.
政府已决定通过这一法案
There are huge crowds in the streets on Sunday.
星期天有大群大群的人在街上。
There are many English-speaking peoples in the world.
在世界上有许多讲英语的人
但应注意,这类集合名词的单数形式有时表示复数概念,所以这些集合名词的单数形式也可归为"单复同形型"中.
2)单数型.这类集合名词表示的是人或事物的整体,即把这类人或事物的全部包括在内,所以只有单数形式.如作主语,谓语动词常用单数。
这类名词常见的有:humanity,mankind,proletariat等.
【例如】The proletariat is the greatest class in the history of mankind. In the fields of production and scientific experiment,mankind makes constant progress.
3)复数型.这类集合名词在形式和内容上是相互矛盾的,就是说它们只有单数形式,但表达的都是复数概念。它强调的是集体中的个体性.这类名词有:police,cattle,faculty,flock,machinery,vermin,personnel等.它们作主语时,谓语动词要用复数.
【例如】The police have caught the murder.
Our personnel are very highly trained.
The vermin are very dangerous.
4)单复同形型.这类集合名词的单数形式既可表示单数也可表示复数.作主语时,用单数动词或复数动词均可,有时意义区别不大.
【例如】The school teaching staff are (is) excellent.
The public is (are) requested not to litter in the park.
The teaching profession claim(s) to be badly paid.
这类集合名词常见的有:class,family,team,crew,board,herd,committee,party,jury,enemy,audience等.
根据说话人的心理意向若把这个集合名词所代表的人或事物看作一个整体,就认为是单数,用单数动词;
若把它所代表的人或事物看作若干个个体的话,就认为其为复数,用复数动词。
试比较:The football team is playing well.
那个足球队打得非常漂亮.
The football team are shavings bath and are then coming back here for tea. 足球队员们正在洗澡,然后来这里吃茶点。
The family is a very happy one.那个家庭是一个非常幸福的家庭。
That family are very pleased about the news of William's success. 全家人对威廉的成功都感到很高兴。

巧记主谓一致原则:
单单复复最常见,集体名词谓用单,如若强调其成员,复数谓语记心间。
有些名词谓常复,people,police即这般。主语单数后接介,谓语单数介无关,
many a作主语也如此,谓语动词应用单。or、nor、but also、there be,近主原则挂嘴边。
关系代词定主语,谓语根据先行词判。不定式短语、动名词,主语从句谓全单。
时间、货币与距离,谓语多单复少见,rest,means,fol1owing等,意义决定其复、单。
none,all,half of等,of之宾语定答案。还有分数、百分数,仍据of之宾定复、单。
代词all指人谓复数,all指事情谓用单。量词用法请注意,谓语要随量词变。
and连接两名词,身兼两职一定冠,no,each,every后单名,两件(种)事(物)系一概念,
以上情况请记清,谓语动词全用单。形容词带the一类人,姓氏复数加定冠,
-s结尾的海峡、山脉与群岛,谓语用复勿用单。neither,either,each,用作主语谓全单。
