名词:
是词性的一种,也是实词的一种,是指待人、物、事、时、地、情感、概念等实体或抽象事物的词。
名词可以独立成句。在短语或句子中通常可以用代词来替代。

名词分类:
一、按意义分类
1.专有名词
表示具体的人,事物,地点,团体或机构的专有名称(第一个字母要大写)。
例:China(中国)、Asia(亚洲) Beijing(北京)、the People’s Republic of China(中华人民共和国)。
专有名词如果是含有普通名词的短语,则必须使用定冠词the。
如:the Great Wall(长城)。
姓氏名如果采用复数形式,则表示该姓氏一家人(复数含义)。
如:the Greens( 格林一家人)。
2.普通名词
表示某些人,某类事物,某种物质或抽象概念的名称。
例如:teacher 老师、tea 茶、 reform 改革。 
普通名词又可进一步分为五类:
①个体名词(Individual Nouns):表示单个的人和事物。
 (car 汽车 room 房间 fan 风扇photo 照片)
②集体名词(Collective Nouns):表示一群人或一些事物的名称。
  ( people 人们 family 家庭 army 军队 government政府 group 集团 )
③复合名词:两个或两个以上名词连在一起构成的名词
 (boy-friend男友 passer-by过路人 brother-in-law内兄)
④物质名词(Material Nouns):表示物质或不具备确定形状和大小的个体的物质。
  ( fire 火 steel 钢 air 空气 water 水 milk牛奶 )
⑤抽象名词(Abstract Nouns):表示动作,状态,品质或其他抽象概念。
  ( labour 劳动 health 健康 life 生活 friendship友情 patience耐力 )

二、按是否可数分类
名词又可分为可数名词(Countable Nouns)和不可数名词(Uncountable Nouns)
1、不可数名词是指不能以数目来计算,不可以分成个体的概念、状态、品质、感情或表示物质材料的东西;
它一般没有复数形式,只有单数形式,它的前面不能用不定冠词a / an。抽象名词,物质名词和专有名词一般是不可数名词
2、可数名词是指能以数目来计算,可以分成个体的人或东西;因此它有复数形式。


名词易混点举例:
一.有些名词既是可数名词,又是不可数名词,但意义有所不同。如:
work(工作) ——a work (著作);                     
 glass(玻璃)——a glass (玻璃杯);            
 aper(纸) ——a paper(报纸;文件;试卷)
tea(茶) ——a tea (一种茶)(表示种类);     
wood(木头) ——a wood (小树林);        
room(空间) ——a room (房间)

二.容易混淆的名词
1.work/job
work是不可数名词,有体力或脑力劳动的意思,又有作为职业概念的工作的意思。
job作为工作,其实有两层含义:一个是干活零工”;一个作为职业的”,是可数名词。 
job意思是a piece of work,指已做或要做、应做的具体的某种工作,实际含义是“职业”,
而work通常指抽象意义上的工作,是不可数名词,也可指“工作场所”。如:
I’m busy today, for I have a lot of work to do.

2. wish / hope
 wish之后可以跟含有动词不定式的复合宾语(wish sb. to do sth.),hope不可以这样用。例如:
I wish you to be happy.我希望你快乐。
 hopewish都可以跟从句。hope之后的从句的谓语动词用一般将来时或一般现在时,所表达的愿望可以实现;
wish
之后的从句的谓语动词用虚拟语气(以后学),表达的愿望无法实现。例如:
I hope you like the flowers.我希望你喜欢这些花。
I wish I were a bird.我希望我是一只小鸟。(虚拟语气)
hopewish都可以跟动词不定式(hope/wish to do sth.)wish比较正式,口气比较强烈;
而用hope所表达的愿望容易实现。例如:
I hope (wish) to go to college.我希望上大学。
wish可接双宾语表示祝愿、祝福,hope却没有这种用法。例如:
I wish you success.我祝愿你成功。

3.silly/stupid/foolish
三个词都含有的意思,但略有不同。
stupid所表达的程度最强,指智力、理解力和学习能力差;
silly
指头脑简单、傻头傻脑,使人觉得可笑,带有一定的感情色彩;
foolish
是普通用语,尤其是在口语中广泛使用。如:
He is stupid in learning math.
他学数学很笨。
Stop asking such silly questions.
别再问这样傻的问题了。
You are foolish to throw away such a good chance.
你真蠢,丢掉这么好的一个机会。

4.instead/instead of

instead/instead of

instead是副词,一般放在句首或句末。
instead of 是介词短语,表示代替, 含有对比的意思,其后常跟名词、代词或v-ing形式。如:

Jack didn’t study law. Instead, he decided to become an actor.

杰克没有学法律,而是决定作一名演员。

If you can’t go to the meeting, I can go instead.

如果你不去开会, 我可以(代替你)去。

Could I have tuna instead of ham?

我能否要金枪鱼而不是火腿?

Miss Wang is ill. I’ll teach you instead of her.

王老师病了,我代替她给你们上课。

We walked down the stairs instead of taking the elevator.

我们走着下楼梯而没有乘电梯。


5.
frightened/afraid/terrible

frightened/afraid/terrible

frightened是由过去分词转化的形容词,常指突如其来的震惊,可用very修饰,在句中作定语、表语、宾语补足语。

afraid只能做表语,多用于习惯经常地惧怕某事物, 泛指一种恐惧心理”;
后接名词、代词、动名词等时,用介词of;接动词时,用带to的不定式;接从句用连词that (可省略)

terrible指极端的恐怖,令人痛苦或不知所措。


6.
learn/study

learn/study

二者都作学、学习,有时可以互换。如:

When did you begin to study/learn English?

你是什么时候开始学习英语的?

study侧重学习的过程;learn侧重学习的结果,常译作学到、学会 :

He studied hard and at last learned the language.

他努力学习,终于学会了这门语言。

study用于较高深或周密的研究;
learn多用于初级阶段的学习或带有模仿性的操作技艺等。如:

He is studying the math problem.

他正在研究这个数学问题。

He learns English on the radio.

他通过广播学英语。

The baby is learning to speak.

这个婴儿正在学说话。


7.
there be/have/own

there be/have/own

there be表示某处(或某时)""(某人或某物),表示客观存在之

have是常用词,表示所属关系,所有

own指合法地拥有某物,强调具有法律上的所有权。


8.
answer/reply

answer/reply

这两个词都可作回答,但用法有所区别。
reply为正式用语,多指经过考虑的、有针对性的、详细的回答,常用作不及物动词,和介词to连用,其宾语为名词或代词,这时可以与answer互换;
answer
既可作及物动词,又可作不及物动词,常指口头或书面的回答,是一般用语。如:

The old man smiled before he replied to my question.

老人在回答我的问题前笑了笑。

I cannot answer you now. 我现在不能回答你。

How shall I answer? 我该怎样回答?

值得注意的是,answer可引申为应答之类的意义,这时不能用reply来代替。如:

answer the door  (门铃响了)去开门

answer the telephone  接电话


名词的语法功能: 
名词在句中作主语,宾语,介词宾语,宾语补足语,表语以及名词短语作状语。
1.主语:The bagis in the desk.书包在桌子里边。
2.宾语:I washed my clothes yesterday. 昨天我洗了我的衣服。
3.表语:This is a good book. 这是一本好书。
4.宾语补足语We selected him our monitor.我们选他为我们的班长。
5.介词宾语Mary lives with her parents.玛丽和她的父母住在一起。
6.定语:She is a Partymember. 她是一位党员。

名词口诀:
一、人和事物各有名,万千名目可辨清。表示名称即名词,具体抽象有不同。
  时间空间和地点,方向位置有专称。主宾定表都可作,名词具有多功能。
二、可数名词不可分,若要分离变性质。不可数名词可分离,一分再分仍原物。

英语名词特殊用法:
1.family指“家庭”时,强调全体;指“家里人”时强调个体,与住房无关
home指“家”,表示同一家庭共同生活的地方,具有感情色彩
Kate has left home for school.可作副词也可作名词,意思是“在家”
house指“住宅”、“住房”The Greens live in a big house.

序数词:
是数词的一种,主要在英语语法中讲到,在汉语中表示为“第几”。如:first, second, third, fourth

序数词的读法与写法:
序数词写法:

1 first ;2 second ; 3 third  ;4 fourth ; 5 fifth ;
6 sixth ;7 seventh; 8 eighth;9 ninth ;10 tenth ;
11 eleventh ;12 twelfth ;13; thirteenth ;14 fourteenth;15 fifteenth
16 sixteenth ;17 seventeenth ;18 eighteenth;19 nineteenth;
20 twentieth ;30 thirtieth ;40 fortieth ;50 fiftieth ;60 sixtieth ;70 seventieth;80 eightieth ; 90 ninetieth

多位序词:
由基数词的形式变结尾部分为序数词形式来表示。
one hundred and twenty-first 第一百二十一
one thousand three hundred and twentieth 第一千三百二十
two hundred and fifty-second 第二百五十二

缩写:
有时,序数词可以用缩写形式来表示。主要缩写形式有:
first——1st ;second——2nd ;third——3rd; fourth——4th ;sixth——6th ;twentieth——20th;twenty-third——23rd
其中lst,2nd,3rd为特殊形式,其它的都是阿拉伯数字后加上th。


序数词前不加the的情况:
在英语中,使用序数词时前面要加定冠词 the,但是,在下面的情况下则不加 the:
1.当序数词前有形容词性物主代词或名词所有格修饰时,序数词前不用 the。
Mother was my first teacher in my life.妈妈是我生命中的第一个老师。
Tom is Lily's third boyfriend. 汤姆是莉莉的第三个男朋友。
2.当表达分数时,序数词前不用 the。
One fifth of the students here are from the country. 这儿1/5的学生来自农村。
Three fourths of the students here are from the country. 这儿的3/4的学生来自农村。
3.当表达“又一,再一”时,序数词前不用 the,但可加不定冠词。
Please give me a second chance. 请再给我一次机会。

5.当序数词在句中作状语时,序数词前不用 the。
Who got there second? 谁第二个到那儿的?
I finished the work first. 我最先完成那项工作。
6. 当表达考试(比赛等)中获得的名次时,序数词前不用 the。
She stands first in her class. 她在班上成绩排名第一。


基数词变序数词的口诀:
基变序,有规律,词尾加上-th。
一,二,三,特殊记,词尾字母t,d,d。
八去t,九除e,ve要用f替,ty将y变成i,th前面有个e。
若是碰到几十几,前用基来后用序。
整十基数变序数,先把ty变成tie,要是遇上两位数,十位基数,个位序,th最后加上去。
或者一,二,三变字体;th从4上起;8加h,9减e;用f 代ve;ty变为tie。

序数词的语法功能及用法:
序数词在句中可作主语、宾语、定语和表语。
The second is what I really need. 第二个是我真正需要的。(作主语)
He choose the second. 他挑选了第二个。(作宾语)
We are to carry out the first plan. 我们将执行第一个计划。(作定语)
She is the second in our class.在我们班她是第二名。(作表语)
注:序数词在使用时,通常前面要加定冠词 the;但是如果序数词前出现不定冠词a或an时,则表示“再—”,“又—”。
We'll go over it a second time. 我们得再念第二遍。
We've tried it three times.Must we try it a fourth time? 我们已经试过三遍了,还必须试一次(第四次)吗?
表示顺序的序数词
只需将基数词放在它所修饰的名词之后即可,不需要添加定冠词。
the first lesson——Lesson One    the fifth page——Page 5(five)
the twenty-first room——Room 21(twenty-one)


副词的比较级和最高级:
当两种物体之间相互比较时,我们要用形容词或副词的比较级;
当相互比较的物体是三个或三个以上时,我们就要用形容词或副词的最高级。
副词比较级和最高级的变化规则和形容词相似。
副词比较级的变化规则:

一、规则变化

1.一般在词尾直接加erest。hard—harder—hardest ;long-longer-longest

2.以不发音的字母e结尾的单词在词尾直接加rst。nice-nicer-nicest

3.以辅音字母+y结尾的词,把y变为i,再加erest。early—earlier—earliest 
4.重读闭音节,末尾只有一个辅音字母,双写这个辅音字母,再加erest,例如,big-bigger-biggest

5.部分双音节词和多音节词分别在原级前加more构成比较级和most构成最高级, carefully—more carefully—most carefully

二、不规则副词的比较级和最高级

 原级 比较级  最高级 
 well  better best 
 badly worse  worst 
 much more  most 
 little  less lest 
 far  farther(指距离) farthest(指距离) 
 further(指距离和抽象概念) furthest(指距离和抽象概念) 

以ly结尾的副词,比较级有两种情况:
一种单词里本身就以结尾early;
另一种是由形容词+变为的副词 slowly,happily ,easily,他们改为比较级时 是不一样的。
例如:第一种情况,直接进行词尾变化early-earlier;
而第二种情况, 就要在副词原级前面+more,构成比较级。
因此,easily 的比较级应该是:more easily 。
副词等级的用法:
一、原级的用法

1.只能修饰原级的词,very,quite,so,too。例如:
He is too tired to walk on.他太累了以至于不能再继续走了。
My brother runs so fast that I can‘t follow him.我弟弟跑得那么快以至于我跟不上他。
2.原级常用的句型结构
(1)“甲+实意动词+(倍数)+as+副词原级+as+乙”表示“甲和乙程度相同”或“甲是乙的几倍”。例如:

二、比较级的用法
1.可以修饰比较级的词,much,a lot,far,…的多; a little,a bit,…一点儿; even甚至;;still仍然。例如:

三、最高级的用法
最高级常用句型结构
(1)“主语+实意动词+(the)+副词最高级+单数名词+in/of短语”表示“……是……中最……的”。例如:
I jump (the) farthest in my class.我是我们班跳得最远的。
(2) “特殊疑问词+be+the+副词最高级+甲,乙,or丙?”用于三者以上的比较。例如:
Which season do you like (the) best,spring,summer or autumn?你最喜欢哪一个季节,春天,夏天还是秋天?
(3)“特殊疑问词+be+the+最高级+甲,乙,or丙?”用于三者以上的比较。例如:
Which country is the largest,China,Brazil or Canada?哪一个国家最大,中国,巴西还是加拿大?
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.
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。
