B.用法总结

（一）基数词的表示方法：基数词用来表示数目，或者说表示数量的词叫基数词。最基本的基数词如下表所示。1one11eleven100ahundred2two12twelve20twenty1000athousand3three13thirteen30thirty1，000，000amillion4four14fourteen40forty10，000，000tenmillion5five15fifteen50fifty100，000，000ahundredmillion6six16sixteen60sixty1，000，000，000abillion7seven17seventeen70seventy8eight18eighteen80eighty9nine19nineteen90ninety10ten1.1-12的基数词：

one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve

2.13～19的基数词，在个位数上加后缀-teen构成，并有两个重音。

thirteen,fourteen,fifteen,sixteen,seventeen,eighteen,nineteen

3.20～90等十位数由2-9加后缀-ty构成。

twenty,thirty,forty,fifty,sixty,seventy,eighty,ninety

4.21-29由十位数20加个位数1-9构成，十位和个位之间加连字符号"－"，其他十位数以此类推。

21twenty-one、44forty-four、98ninety-eight5.英语中没有“万”这个读数单位，要表示汉语中的“万”，英语需借用thousand一词，如“一万”用“十个千”表示(tenthousand)，“十万”用“一百个千”表示(onehundredthousand)。6.用作基数词单位的hundred,thousand,million,billion通常不带复数词尾-s，但若用于表示数百、数千、数百万这样的泛指，则用复数。如：Abouttwothousandpeoplediedintheearthquake.大约有两千人在地震中丧生。Thousandsofpeoplegototheseasideeveryyear.每年成千上万的人到海滨去。7.表示整十的基数词用复数形式可以表示人的大约岁数或年代。如：Heisinhisearlytwenties.他才二十出头(from)。Thistookplaceinthe1930s.这事发生在20世纪30年代。

8.多位数的读法

①从后向前数，每三位数加一个"，"；第一个"，"号前为thousand（千），第二个"，"号前为million（百万）……，然后再逐段表达。

②三位数数词要在百位和十位（若无十位则和个位）之间加and。

45，632，798读作

forty-fivemillion,sixhundredandthirty-twothousand,sevenhundredandninety-eight

（二）序数词的表示方法：第一到第十第十一到第十九第二十以上firsteleventhtwentiethsecondtwelfththirtieththirdthirteenthfortiethfourthfourteenthfiftiethfifthfifteenthsixtiethsixthsixteenthseventiethseventhseventeentheightietheightheighteenthninetiethninthnineteenthhundredthtenththousandth1.序数词=基数词+th，但以下几个特殊：

one-first,two-second,three-third,five-fifth.eight-eighth,nine-ninth,twelve-twelfth,twenty-twentieth……,ahundred-ahundredth2.twentieth,thirtieth,fortieth等表示整十的序数词，由相应的基数词将词尾y改为ie，再加-th构成。3.first,second,third通常可缩写为1st,2nd,3rd。凡是以th结尾的序数词可缩写为“基数词+th”：4th,5th,9th,11th,60th,128th等。4.非整十的多位数，将个位数变成序数词即可：twenty-first(第21)，thirty-sixth(第36)，ninety-ninth(第99)，threehundredandsixty-fifth(第365)等。5.hundred,thousand,million等序数词形式为hundredth,thousandth,millionth等。6.序数词前通常要用定冠词，但表示考试或比赛等的名次时，通常可省略其前的定冠词。如：Myroomisonthesecondfloorandhisonthethird.我的房间在三楼，他的房间在四楼。Hewas(the)thirdintheexam.他考试得了第三名。注：有时序数词前不用定冠词，而用不定冠词，表示次第在原有基础上的增加。如：We’llhavetodoitasecondtime.我们得再做一次

（三）倍数、分数、小数、百分数的表示方法：

1.倍数：英语中表示倍数时通常借助half,double,twice,threetimes等之类的词。如：Thisroomisthreetimesaslargeasthatone.这个房间有那个房间三个大。

Threethreesarenine.orThreetimesthreeisnine.三三得九。

2.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，当分子超过“1”时，分母用复数。如：twothirds=2/3 threefifths=3/5注：1/2通常读作a[one]half，一般不读作asecond；1/4可读作a[one]fourth，也可读作a[one]quarter。数短语作主语时，谓语的数由of后面的名词来决定，名词为可数名词复数，则谓语用复数；名词为不可数名词，谓语用单数。

Athirdofthelandiscoveredbyforests.

Twothirdsoftheworkersareworkinghard.

3.小数：小数点前的数按总数念，同其它基数词读法一样，小数点用point，小数点后面的数按基数词一个一个单独念。如9.65读作ninepointsixfive。218.39读作twohundredandeighteenpointthreenine。1.25读作onepointtwofive

0.56读作naughtpointfivesix或zeropointfivesix

4.百分数。百分数由基数词和百分号(%)组成，百分号(%)读作percent。如：thirtypercent=30%60percent=60%（四）表示日期1949年1949读作nineteenforty-nine6月23日June23rd读作June(the)twenty-third或thetwenty-thirdofJune2006年10月October2006读作October,twothousandandsix1600年5月2日May2nd,2005读作thesecondofMay,sixteenhundred（五）表示钟点半小时用half，一刻钟用aquarter，半小时以内用past，超过半小时用to。08:00eighto’clock或eight09:15ninefifteen或aquarterpast/afternine02:30twothirty或halfpast/aftertwo05:45fiveforty-five或aquartertosix（六）表示约数1.用tens/dozens/scores/hundreds/thousands/millionsof表示“几十、几百、上千、成千上万”等。如：Theboyboughtdozensofpencils.那个男孩买了几十支铅笔。Thousandsofpeoplediedintheearthquake.数以千计的人死于地震。2.用lessthan,under,below,almost,nearly,upto等来表示小于或接近某数目。如nearlytwohours将近两个小时。3.用morethan,beyond,ormore,over,above等来表示超过或多于某个数目。如morethan100years一百多年。4.用or,orso,about,around,some,moreorless等表示在某一数目左右。如about50pens大约五十支钢笔，amonthorso大约一个月。5.用to,from…to…,between…and表示介于两数词。如：Hissalaryrosefrom100dollarsamonthto120dollarsamonth.他的工资从每月100美元升到了每月120美元。_（七）算式表达法：

1.加法

A+B=C→AplusBisC.orAandBisC.

2.减法

A－B=C→AminusBisC.orBfromAisC.

3.乘法

A×B=C→AtimesBisC.orAmultipliedbyBisC.

4.除法

A÷B=C→AdividedbyBisC.

5.大于

A>B→AismorethanB.

6.小于

A<B→AislessthanB.

第二节：thesecondsection;SectionTwo

第三课：thethirdlesson;LessonThree

长安街76号：seventy-sixChang'anStreet

电话号码：204-2244：telephonenumbertwoo（零）fourtwotwo（doubletwo）fourfour

eg.公元1995年：1995（=nineteenninety-five）

（2）日期使用一般的序数词来读取

eg.5月10日：May10th（=Maytenth）

（3）时刻通常用基数词来读

eg.8点45分：8:45（=eightforty-five）

（4）年代表示法：

eg.二十世纪九十年代：1990'snineteennineties

eg.twothousand两千thousandsof成千上万

hundredsof成百上千millionsof数以百万计

Thousandsandthousandsofpeoplehavevisitedthecity.

eg.afour-year-oldboy

2.有些结构既有基数词又有序数词。

eg.thefirstthreequestions
