不可数名词:

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 ,若要表示它的个体意义时,一般要与一个名词短语连用,相当于中文里的【一 +(量词)+ 名词】,其中的量词意义依与具体的名词搭配而定。
 例如:
a cup of tea 一杯茶
a piece of news 一则新闻 
two pieces of paper 两张纸  
three glasses of water 三杯水 
 five bags of rice 五袋大米
不可数名词量的表示:
1、不可数名词的数量一般用some , much , a lot of , lots of , a bit of , a little , little等数量形容词表示。
eg: some meat 一些肉    
a lot of money很多钱     
a little water 一点水

2、不可数名词的数量还可以用适当的量词(由普通名词充当)作单位来表示,
结构为“数词+量词(普通名词)+ of + 不可数名词”。
其单复数变化就体现在普通名词上。
eg: a piece of paper 一张纸    
three pieces of paper 三张纸

不可数名词记忆歌诀:
不可数名词很特殊,
六点用法应记清楚:
一是没有复数形式,
二作主语谓须单数①,
三是其前不用a(an),
四是修饰不用基数②,
五可much, some和any来修饰,
六表数量用“计量+of”短语③。
[说明]:
①不可数名词作主语时,谓语用单数,如:There is some milk in the bottle.
②不可数名词不可直接用不定冠词和基数词直接修饰,但可用some、any和much等词修饰;
③当表示不可数名词的数量时,其前应用“计量名词+of”短语,注意计量名词有复数形式。如:I’d like two cups of tea.

不可数名词复数形式的特殊含义:
英语中的专有名词、物质名词和抽象名词一般为不可数名词,但有时它们却可用作复数形式。
此时它们往往又有了新的含义。
一、专有名词的复数形式的含义
1.表示一家人或夫妻。例如:
Are the Smiths coming to our party tomorrow night?史密斯一家明晚会来参加我们的聚会吗?
2.表示同名或同姓的若干人。例如:
There are two Marys and three Roberts in his class.他班上有两个玛丽和三个罗伯特。
 Did the Mr. Blakes come this morning?那几位布莱克先生今天上午来了吗?

二、物质名词的复数形式的含义

First of all,he wrote out a long list of all the foods which were forbidden。

2.表示量很大,远远超过该词原来表示的程度或次数。这一类词常见的有:
sands(沙滩,沙漠),waters(水域),rains(大阵雨、雨季),winds(大风),times(时代), woods(森林),ruins(废墟),rags(碎片、破衣服),ashes(灰烬、骨灰)。例如:

Send two coffees and three lemonades to the room.请将两杯咖啡和三杯柠檬汁送到这个房间。
4.某些物质名词又是个体名词,它们的复数形式表示与原来个体完全不同的东西。这类词有:
glasses(眼镜、玻璃杯), irons(熨斗),coppers(铜币),papers(文章,
证件)等。例如:
She is always wearing glasses.她总是戴着眼镜。
He wrote many papers for the newspaper.他为这份报纸写过许多文章。

三、抽象名词的复效形式的含义
1.congratulations, regards, respects,thanks,wishes,apologies等复数形式用来
表示祝愿、礼貌和客气。例如:

cares(烦人的事),anxieties(令人着急的事),worries(使人发愁的事),difficulties(难题),joys(使人高兴的事),failures(失败的事,失败的人),friendships(表示友谊的事例)等。例如:
After listening to his advice,she had no more anxieties.听了他的建议,她不再有发愁的事了。
His friendships never last very long.他与别人的交情从来都不长久。
After many failures,they finally succeeded.经过多次失败之后,他们最后成功了。
4.某些抽象名词在某种场合是个体名词,它们的复数形式表示与该个体名词不同的意义,如:
youths(男青年、小伙子), relations(亲属), beauties(美人),necessities(必需品)等。例如:

形容词的位置:
1.形容词一般放在名词前作定语  
单个形容词修饰名词时,一般要放在名词的前面。它们的前面常常带有冠词、形容词性物主代词、指示代词、数词等。例如:  
a red flower一朵红花
an interesting story一个有趣的故事  
six blind men 六个盲人
my own house我自己的房子
如果有两个或两个以上的形容词修饰一个名词时,则由它们和被修饰的名词之间的密切程度而定,越密切的形容词越靠近名词。
如果几个形容词的密切程度差不多则按音节少的形容词放在前面,音节多的形容词放在后面。  
2.当形容词所修饰的词是由some,any,every,no等构成的不定代词时,形容词必须置于名词之后。例如:  
    She has something new to tell me.她有一些新的情况告诉我。  
    I have nothing important to do today.今天我没有重要的工作要做。  
    Do you know anybody else here?这儿你还有认识的人吗?

    This is a kind of flowers easy to grow.这是一种易栽的花。  
4.用 and 或 or 连接起来的两个形容词作定语时一般把它们放在被修饰的名词后面。起进一步解释的作用。例如:  
    All people,young or old,should be strict with themselves.  
    所有的人,无论老少,都应该严格要求自己。  
    We are building a new school, modern and super.

    All countries, rich and poor, should help one another. 所有的国家,无论穷富都应该互相帮助。  
5.有少数形容词,如enough和possible,既可置于所修饰的名词前面也可以置于它所修饰的名词之后。例如:   
Do you have enough time(time enough)to prepare?你有足够的时间做准备吗?   
Maybe it will be a possible chance(chance possible)for you.或许它将成为一次可能的机遇。
6.有些形容词,置于名词之前与之后,含义不尽相同。例如:  
the writer present 出席的作者  
the present writer 现在的作者
7.表示长,宽,高,深,及年龄的形容词,应放在相应的名词之后。
This river is about 100 metres wide.

 Do you have anything else to say?
10.由两个或两个以上的词组成的形容词词组修饰名词时须放在名词之后。
This is the book easy to read.
这是一本容易读的书。


形容词知识拓展:
名词化的形容词:
有些形容词可以和定冠词连用,表示一类人或事物,这时,它相当于一个名词,可作主语或宾语;
表示一类人时,看作复数,表示一类事物时,通常看作单数。
Robin Hooh(罗宾汉) hated the rich and loved the poor.
The old are taken good  care of in American.
the+形容词,常见的短语有:
the old/the young/the sick/the white/
the black/the rich/the poor/the dead(死者)

形似副词的形容词:
以-ly结尾的词通常是副词,但是下列词为形容词。

复合形容词的类型:
(1)名词+过去分词  man-made satellite 人造卫星
(2)形容词+现在分词  a good-looking man

某些现在分词和过去分词可作形容词
the moving story 令人感动的故事

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:

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

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.
