如:107→one hundred and seven;765→seven hundred and sixty-five⒉1,000以上的数的读法:先从后向前数,每三位数加一个逗号,第一个逗号前的数字用thousand(千),第二个逗号前的数字用million(百万),用“几十thousand“表示“几万",以“几百thousand"表示"几十万”,用“几十million"表示“几千万",用“几百million"表示"几亿"。

如:13,789,653→thirteen million seven hundred and eighty-nine thousand six hundred andfifty-three2数词的复数形式⒈表示几十岁时。

数词考点大盘点数词在高考中虽然不像其它词类那么"热",但也有其考查的重点和难点,须引起同学们的注意。

一、考查基数词的用法1. 基数词hundred, thousand, million等表示确切数目时,其词尾不能加-s,其前面可用数词或several, some等修饰;当表示笼统数目时,其词尾要加-s,可跟of连用,其前不能用数词,但可以用several, some等修饰。

【原题再现】________ people in the world are sending information by e-mail every day.A. Several millionB. Many millionsC. Several millionsD. Many million【解析】 million前可用several修饰,此时其后不能加-s, many不能修饰million。

表达"几百万"也可用millions of。

答案为A。

2. dozen和score的用法要注意以下几点:1) dozen与数词或many, several等连用时,不加-s,所修饰的名词前常省去of。

如two (many, several) dozen pencils。

但是,在a dozen of these / those people, two dozen of them等短语中应加of,这是习惯用法。

2) two score of people中应加of,但在three score and ten people(70人)中,不加of。

3) 表示"几十;许多"时,可使用dozens of; scores of形式。

高考英语《中学英语语法全程复习》之--数词

高考英语《中学英语语法全程复习》之--数词

四.数词一.数词的定义数词是表示数目多少或先后顺序的词,有基数词和序数词两种。

表数量的数词叫基数词,如one, two, three。

表顺序的数词叫序数词,如first, second, third, fourth, fifth,...二.基数词(一)构成1)1~12单独记one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve2)13~19词尾为-teen:thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen3)20~90逢整十词尾为-ty:twenty,thirty,forty,fifity,...4)21~ 99在十位数和个位数之间加连字符构成,如:73 seventy-three, 88 eighty-eight5)101~ 999先说几百,再加and,再加末尾两位数,如:178 one hundred and seventy-eight6)1000以上的数词,先从后向前数,每三位用一个数逗点“,”隔开。

第一个“,”是thousand千,第二个“,”是million百万,第三个“,”是billion 美语中的十亿(英国用thousand million),然后ten thousand 10,000表示②十万的表示法:one hundred thousand 100,000③百万的表示方法:a/one million 1,000,000④千万及以上的表示法:2百亿 twenty thousand million(英),twenty billion(美)万亿,兆a trillion=a million million=1012,(旧指-尤英国,百万兆,1018)(二)基数词的使用基数词可在句中作主语、表语、定语、状语、介宾、同位语。

三、数词★基数词表示数量的词叫基数词。

1-12的基数词是独立单词;13-19的基数词都是以-teen结尾的,要注意thirteen,fifteen,eighteen的拼法稍有不同;20-90的十位数,以后缀-ty结尾,要注音twenty,thirty,fifty,eighty的特殊点。

如下表:1基数词的读法⒈三位数的读法:第一个数字+hundred +and+后面的一位或两位数字。

如:107→one hundred and seven;765→seven hundred and sixty-five⒉1,000以上的数的读法:先从后向前数,每三位数加一个逗号,第一个逗号前的数字用thousand(千),第二个逗号前的数字用million(百万),用“几十thousand“表示“几万",以“几百thousand"表示"几十万”,用“几十million"表示“几千万",用“几百million"表示"几亿"。

如:13,789,653→thirteen million seven hundred and eighty-nine thousand six hundred andfifty-three2数词的复数形式⒈表示几十岁时。

如“二十多岁”说twenties,表示的是20岁到29岁。

依次类推,thirties 表示“三十几岁",forties 表示四十几岁”,但十几岁”不可说tens,而要说teens,指13岁至19岁。

如:He died in his thirties.She is in her teens.⒉表示几十年代时。

如:“二十世纪八十年代”写成1980s或1980s,均读作nineteen eighties,指的是1980至1989年这十年间,需注意的是,年代用文字表示时则不可用-s形式。

如:Great changes took place in the l970s.History has entered the eighties.⒊表示不确定数目时。

这时要在million,thousand,hundred 等词后加上-s并与of连用,表示大约多至“数以.…….计",但millions of等前不能再加基数词,却可加some,several等表示不确定数目的修饰语。

如:Millions of other stars are even bigger and brighter than the sun.Some hundreds of new buildings have been put up here this year.⒋在分数中,当基数词(表示分子)大于one时,序数词(表示分母)要用复数,两者之间用不用连字符号均可。

如:Two thirds of the teachers in our school are women.She has spent four-fifths of her money.⒌当基数词用作可数名词或用于某些固定词组中时,也要用复数。

如:How many sevens are there in forty-nine?They arrived by twos and three她们三三两两的来了。

3数词和名词单数一起作定语,中间用连字符连接如:a seven-year-old girl 一个七岁的女孩a two-thousand-word article一篇2千字的文章4基数词和序数词的顺序问题当基数词和序数词同时修饰一个名词时,序数词一般放在基数词前;但如果序数词充当描绘性修饰时,则放在基数词后。

如:He is one of the first five students.他是前五名的学生之一。

★序数词表示数目顺序的词叫序数词。

序数词的构成规则,如下表:1序数词前不用定冠词的情况⒈表示顺序的语气很弱,具有“又一”“再一”的意思时,其前要用不定冠词,不用定冠词。

如:He cast the net a second time.A third bullet passed.⒉序数词前己有指示代词、物主代词、名词所有格或every时,不用定冠词。

如:He made his frist set in an old box.⒊在表示分数的序数词前不用定冠词。

如:From then on Bashi tourer three-fourths of Beijng.Two-thirds of the area is covered by trees.⒋数词与名词构成复合名词时,不用定冠词。

如:There is a first-class hotel over there.He went toa second-hand bookshop.⒌在一些由序数词构成的固定词组里不用定冠词。

如:at firstfirst of allfrom first to last2数词的功能⒈表小数、分数和百分数①小数点读作point,零读zero或nought。

小数点后的数字按个位基数词依次读出。

如:3.4→three point four0.2→zero(nought)point two0.03→zero point zerothree3.458→three point four five eight②百分数由基数词后直接加percent(per cent构成。

如:20%→20 percent③分数由基数词(分子)和序数词(分母)合成。

分子大于1时,表分母的序数词要用复数形式。

如:1/3-→one/a third2/3→two thirds但1/2一般用a/one half;1/4用a/one quarter或one fourth。

④表示几分之几(或百分之几)的人或物时,须在分数(或百分数)和人或物间加of。

若充当主语,谓语动词的数须与of后的名词的数保持一致。

如:One third of the students are girls.1的学生是女生。

Sixty percent of her income was spent on cloths收入的60%在了服装上。

但当表示人口的几分之几(或百分之几)作主语时,谓语动词常用复数形式。

如:The population in China is very large,and eighty percent of it are far mers.中国的人口众多,其中80%农民。

⒉表加减乘除①加法的表达法如表达“几加几是多少",可用“What/How much is+基数词+and/pus+基数词?";如表达几加几等于几”,可用“基数词+and+基数词+is+基数词"。

如:What/How much is seven and eight?7加8是多少?Seven and eight is fifiteen.7加8等于15。

②减法的表达法如表达“几减几是多少”,可用“What/How much is+基数词+minus+基数词?";如表达“几减几等于几”,可用“基数词+minus+基数词+is+基数词"。

③乘法的表达法如表达“几乘几是多少",可用“What/How much is基数词+times+基数词?";如表达几乘几等于几”,可用“基数词+times+基数词+is+基数词"。

④除法的表达法如表达“几除以几是多少",可用“What/How much is基数词+divided by+基数词?";如表达几除以几等于几”,可用“基数词+divided by+基数词+is+基数词"。

⒊表时间①用数字表达法来表示几点几分时,分钟数在后,并且不可使用quarter,half。

如:8:15 eight fifteen不能说:eight a quarter10:30 ten thirty 不能说:ten half②使用介词past表示“几点过几分”,用to表示“几点差几分”时,分钟数放在介词前。

11:25 twenty-five past eleven(=eleven twenty-five)6:40 twenty to seven(=six forty)③past,to 前的分钟应小于三十分钟(如果正好是三十分,应用half)。

如:5:55 five to six=five fifty-five不能说:fifty-five past five)5:30 half past five=five thirty不能说:thirty past five或five half)④数词用于编号表示编号,可以用基数词,也可以用序数词,即:事物名词(不加冠词)+基数词;the+序数词十事物名词。

如:Lesson Twelve=the Twelfth Lesson第十二课Part One→the First Part第一部分World War I=the First Word war第一次世界大战如英语编号中数字较长,一般用基数词表示。

如:Room 506第五0六号房间page 265第二百六十五页Telephone NO.8297976电话号码8297976⑤表倍数两倍:twice两倍以上:基数词+times如:This classroom is twice as big as that one.The house is three times bigger than that one3数量名词的单复数形式⒈hundred,thousand,million的用法①当前面有数词以及many,several 等词修饰时,这三个词用单数形式,后面直接跟复数名词。

如:two hundred students 200名学生several thousand enemies 几千敌人②当这几个词前面没有数词而后面有of时,则一定要用复数形式,表示数百、数千等笼统的数目概念。

如:hundreds of dollars 数百美元millions of ants数百万蚂蚁⒉score(二十),dozen打;十二个)的用法①当dozen与基数词或many ,several等连用时,不加“-s”,所修饰的名词前常省去of。

但是,在a dozen of these people,two dozen of them等短语中应加of。

这是因为习惯上在these,those,us等词前该用dozen of的缘故。

如:two dozen books两打书two(many several)dozen pencils两(几)打铅笔some dozen people“若干打的人(许多人)"②score意为“二十"。
