据专家权威分析,试题“Many students in China are nearsighted. The underlined part..”主要考查你对  不可数名词,形容词  等考点的理解。关于这些考点的“档案”如下:

不可数名词形容词

考点名称:不可数名词

  • 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 ,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

    3、一些常见的用来表示不可数名词数量的词
    ①piece(条、块、片、张、份、则)
    eg: a piece of meat 一块肉   
    a piece of bread 一片面包    
    two pieces of advice 两条意见
    a piece of news 一条消息/一则新闻
    ②glass(玻璃杯) , cup(茶杯) , bottle(瓶)
    eg: a glass of milk 一杯牛奶    
    a cup of tea 一杯茶    
    six bottles of beer 六瓶啤酒
    ③loaf(条)、bar(块)、tin(听,罐)
    eg: a loaf of bread 一条面包    
    a bar of soap 一块肥皂    
    a tin of tobacco 一听/罐烟丝
    ④basket(篮)、bag(袋)、box(箱,盒)
    eg: a basket of food 一篮食物   
    five bags of rice 五袋大米    
    a box of wine 一箱白酒

  • 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
    1.表示不同的种类,如food,wine,metal, wheat,rice等。例如:
    The wines of France are among the best in the world.法国的葡萄酒是世界上最好的,
    First of all,he wrote out a long list of all the foods which were forbidden。
    首先他列出了一长串禁用的食品。
    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:
    The rising waters did a lot of harm to the crops.上涨的河水给庄稼造成了很大的损害。
    These caves collapse easily in heavy rains.下大雨时这些洞穴容易倒塌。
    The children are playing on the sands.孩子们在沙滩上玩。
    3.某些表示饮料名称的物质名词往往以复数形式代替单位词。这类词有:coffees,teas等。例如:
    The waitress has served twenty teas since four o’clock.从四点起,这位女服务员已上了二十份午茶。
    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:
    It’s your birthday today.Congratulations!今天是你的生日,恭喜你!
    You’ve given me so much help.Thanks a lot.你给了我很多帮助,非常感谢。
    2.smiles, pities, fears, hopes, kindnesses复数形式表示强调。例如:
    He was all smiles.他满脸笑容。
    It is a thousand pities.非常遗憾。
    I have received many kindnesses from him.他对我非常好。
    Great fears are felt for the safety of the missing climbers.人们对失踪的登山者的安全权为担忧。
    3.抽象名词具体化。有些抽象名词的复数形式表示具体的事物,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:
    Twenty youths attended the meeting yesterday.二十个男青年出席了昨天的会议。
    All his poor relations came to spend their holidays at his home.他所有的穷亲戚都在他家过节。

  • 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??  
    3.形容词后面有介词短语或不定式短语时,形容词必须置于名词之后。例如:?  
        It is a problem difficult to work out.?这是一道难以解决的问题。?  
        Edison is a student difficult to teach.?爱迪生是个很难教的学生。?  
        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.?  
        我们正在建一所现代化的高档次的新型学校。?  
        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.
    The building is more than 50 metres tall.
     He is less than 40 years old.
    8. enough修饰名词时,在名词前后都可以。
    They said that they had enough food.= They said that they had food enough.
     enough 修饰形容词和副词,位于其后。
     He is old enough to join the army.
     He isn’t old enough to go to school.
    9.形容词else通常放在疑问代词,疑问副词或不定代词后
     what/who/where/when/when else
     something/anything/nothing…else
     What else did you do?
     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/
