三、考点梳理

知名教师分析,《_____of the students in our class_____ interested in micro blogs (微博) on the Internet.[ ]A. Two fift》这道题主要考你对 主谓一致分数 等知识点的理解。

关于这些知识点的“解析掌握知识”如下:

知识点名称:主谓一致,分数

考点名称:主谓一致
  • 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。
    We are sure he will come. 我们肯定他会来。
    使用语法一致的情况
    (1)当主语是and,both…and连接的并列结构

  • "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.
    3,"half of,the rest of,most of,all of及百分数或分数+of 等后接名词"作主语时,谓语动词形式根据of后的名词而定.例如:
    Three fourths of the surface of the earth is covered with water.地球表面四分之三为水所覆盖.
    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:
    No book and no pen is found in the schoolbag.书包里没有书和钢笔.
    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.
    11,以-ics结尾的学科名词,如politics,physics,mathematics等作主语时,谓语动词用单数.以-s结尾的名词news,works,plastics等同属此类.例如:
    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:
    One and a half apples are left on the table. 桌子上有一个半苹果.
    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.
    15,"one of+复数名词+ 定语从句"结构中,定语从句的谓语动词要用复数;而在"the only one of +复数名词+定语从句"的结构中,"the one of + 复数名词+定语从句"定语从句的谓语动词要用单数.例如:
    He is one of the students who get there on time.他是准时到达那里的学生之一.
    16,表示时间,距离,金钱等的复数名词作主语表达一个整体概念时,谓语动词常用单数,但若强调数量,谓语动词可用复数.例如:
    One million dollars is a lot of money. 一百万美元是一大笔钱.

  • 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。
考点名称:分数
  • 分数:
    由基数词和序数词构成—分子用基数词,分母用序数词,分子超过“1”时,分母用复数。
    例如:a/onesixth(1/6),twothirds(2/3)
  • 英语分数的表示法:
    一、用“基数词+序数词”表示
    1.分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子,序数词表示分母。
    如:
    The centimeter is one-tenth of the decimeter or one-hundredth of the meter.厘米是分米的十分之一,或者说是米的百分之一。
    However,the number of boys will bea third or less than the girls in the class.但是,班里男生的人数将比女生少三分之一或更少。
    从以上例子可以看出:
    ①分子除用one外,也可用a;
    ②如果分子大于1,分母要用复数形式。但是,1/2不能说a(one)second,而要说a(one)half。例如:
    The sum of one half,one third and one fourth of a certain number is 13.某数的1/2,1/3和1/4的和是13。
    1/4 和3/4可以说a(one)fourth和three fourths,但常用a quarter和three quarters表示。
    ③应该注意的是,分数修饰名词时,若该名词是不可数名词只能用单数;
    ④若是可数名词,用单数或复数均可。但是,若它们在句子中作主语,则谓语动词是用单数还是复数取决于名词,即与分数所修饰的名词保持一致。例如:
    Only one-fifth of air consists of oxygen.氧气只占空气的1/5。
    About two thirds of the students attendthe meeting.大约2/3的学生都参加了会议。
    2.带分数也是常见的英语数词表达。所谓带分数,实际上是“整数+分数”,表达时分而述之,只是整数部分与分数部分要用连词and连接。
    当带分数修饰名词时,该名词通常是复数,但若名词置于整数one或a之后,则用单数。
    “带分数+名词”作主语时,谓语动词根据临近原则要用复数。例如:
    You should finish the work within one and a fourth hours.你应在1.25小时内完成工作。
    The atom breaks up in a minute and a quarter.原子在1.25分钟内裂变。

    二、用percent等表示
    表示百分之一可以说one(a)hundredth,但更常用one percent或percent,即用百分数表示法来表达。例如:
    Our bodies are 65percent water.我们人体含65%水分。
    Seventy-five percent of the earth'ssur- face is covered by water.地球表面的75%被水覆盖着。
    Eighty-five percent of the students in English department are girls.英语系85%的学生是女生。

    三、用part表示
    名词part有“……分之一”的意思,分子大于1时,part用复数。表示分数的结构一般有以下三种:
    1.“基数词(或a)+序数词+part(s)” a hundred part百分之一
    2.“基数词+part(s)+in+基数词” five parts in one thousand千分之五
    3.“基数词+part(s)+per+基数词” one part per million百万分之一

    四、用“基数词+介词+基数词”表示
    借助介词表示分数,介词前的数词是分子,介词后的数词是分母。例如:
    1.Ninety- nine people out of a hundred,if they were asked who first found America,would answer Clumbus.
    如果要问是谁首先发现美洲,一百个人中有九十九个(百分之九十九)将回答是哥伦布。
    这种结构中的介词主要有in,out of,of 以及to
    2.The map is drawn to a scale of one of ten thousand.
    这张地图是按万分之一的比例绘制的。

  • 英语分数表示法:
    一般情况下,表示分数时,分子要用基数词,分母用序数词(first, second, third ...)。
    如果分子大于1,分母必须用复数形式。
    1. "1/2"或"一半"的表示方法:
    用one half或a half表示。例如:
    半英里:one (a) half mile或half one (a) mile
    一个半小时:an hour and a half或one and a half hours (hour要用复数形式)

    2. "1/4"的表示方法:
    用one (a) quarter表示。如果分子大于1, quarter用复数形式。例如:
    1/4  one (a) quarter
    3/4three quarters

    3. 如果分子大于1,分母要用序数词的复数形式。
    如果分数大于1,要用整数部分+ and + 分数表示。例如:
    1/3  one third或a third
    5/6 five sixths
    8 3/5 eight and three fifths

    4. 比较复杂的分数用over表示。
    分子(基数词)+ over + 分母(基数词)。注意这里分子、分母全用基数词表示。例如:
    51/80 fifty-one over eighty
    77/232 seventy-seven over two hundred and thirty-two

    5. 用"分子(基数词)+ (out) of + every + 分母(基数词)"表示。这里分子、分母也全用基数词表示。例如:
    1/7one of every seven
    5/9five out of every nine
    eg: An investigation showes that about two of every three students in this university are from China.
    一项调查表明这所大学大约有三分之二的学生来自中国。

    6. 用"分子(基数词)+ in + 分母(基数词)"表示。这里分子、分母也全用基数词表示。例如:
    1/3 one in three
    5/6 five in six
    eg: Only about one in five books was written for children ranged from seven to ten years old.
    只有大约五分之一的书是为七到十岁的儿童写的。

    7. 用"表示减少意义的动词或词组+ 倍数"表示减少了n-1/n。例如:
    eg: The time for the whole journey is shortened 3 times.
    整个行程的时间缩短了三分之二(或缩短到原来的三分之一)。

    8. 当分数后面接名词时,如果分数表示的值大于1,名词用复数;如果小于1,名词用单数。
    3 3/5 kilograms 三又五分之三千克(读作three and three fifths kilograms)
    4/5 meter 五分之四米(读作four fifths meter)
    5/6 inch 六分之五英寸(读作five sixths inch)
  • 百分数表示法:
    百分号%读作percent (per cent),无复数形式,数词要用基数词,应用时常与by连用。例如:

    数字

    表示法

    6%

    six percent

    0.58%

    (naught) point five eight percent

    200%

    two hundred percent

    The output of petroleum went up by twenty percent.石油产量增长了20%。
    The price of food was reduced by ten percent. 食品的价格下降了10%。
    The loss of electricity has been reduced to less than thirty percent.电的损耗减少到30%以下。 
    注意:
    由"分数(或百分数)+ of + 名词"构成的名词词组作主语时,其后的动词形式依of词组中的名词类别而定。例如:
    Two thirds of the swampland has been reclaimed for farming. 三分之二的沼泽地已经开垦为农田了。
    Over sixty percent of the doctors were women. 超过百分之六十的医生是女性。
