一、序号表示法1．单纯的序号，可在基数词前加number，简写为No.如：No.1第一号2．事物名词的序号表达法1)对于一些小序号可用序数词也可用基数词表达，形式分别为：the＋序数词＋名词；名词＋基数词。如：第一次世界大战可以表示为theFirstWorldWar或WorldWarOne。2)对于一些大序号我们通常只用一种表达法，即名词＋数词。如：501号房间表示为Room501,538路公共汽车表示为Bus538。3)可用a/the＋number＋基数词＋名词。如：aNo.5bus一辆5路公共汽车theNo.8bus那辆8路公共汽车二、倍数的表达方式一般情况下我们用以下三种倍数表达方式：1．倍数用在as＋形容词/副词(原级)＋as结构之前。如：Theyhavethreetimesasmanycowsaswedo.2．倍数放在形容词或副词的比较级之前或by＋倍数用在比较级之后。如：Thisropeisfourtimeslongerthanthatone.Theyproducedmoreproductsin2001thanthosein2000bytwice.3．倍数用在表示度量名词前，其基本结构为：倍数＋the＋size/length/weight…＋of＋表示比较对象的名词，也可用于倍数＋what引导的从句中。如：Thisroomisthreetimesthesizeofthatone.Thecollegeistwicewhatitwas5yearsago.Youcan'timaginethatratseat40to50timestheirweight.三、大约数的表示方法1．用ten，dozen，score，hundred，thousand，million等数词的复数后加of短语来表示几十、几百、上千、成千上万等大约数概念。如：Thelittleboybuysdozensofpencilseveryterm.Thousandsofpeoplediedintheearthquake.EveryyeartensofthousandsofpeoplegotoworkinGuangdongProvince.2．用lessthan，under，below，almost，nearly，upto等来表示小于或接近某数目。如：HeisgoodatEnglish,sohecanfinishthepaperinlessthantwohours.3．用morethan，over，above，beyond，ormore等来表示超过或多于某个数目。如：PekingUniversityhasahistoryofmorethan100years.4．用or、orso、about、around、some、moreorless等表示在某一数目左右。如：About50peoplewerepresentatthattime.5．用to，from…to…，between…and…表示介于两数词之间。如：Hissalaryrisesfrom20dollarsaweekto35dollarsaweek.6．注意事项：dozen，score，hundred，thousand，million作数词表示确切数量时，不用复数。如：threescore,fivedozen,sevenmillion等。四、分数的表达方式1．分子用基数词，分母用序数词，分子大于1时，分母用复数。如：one­third三分之一，three­sevenths七分之三2．分子与分母之间加in,分子在前，分母在后，分子分母都用基数词。如：oneinten十分之一，fiveineight八分之五3．分子与分母之间加outof,分子在前，分母在后，分子分母都用基数词。如：oneoutoften十分之一，fiveoutofeight八分之五五、百分数的表示法1．表示百分数时直接将数词放在单词percent前面即可，如：twentypercent百分之二十2．分数和百分数后面不能直接接名词或代词，而用以下形式：分数/百分数＋of＋冠词/限定词＋名词/代词，其谓语动词与of后的名词在人称和数上保持一致，如：Two­thirdsofthemoneywasspentonfood.Aboutseventypercentoftheearthsurfaceiscoveredbywater.六、小数的表示法如：9.65表示为ninepointsixfive218．39表示为twohundredandeighteenpointthreenine一、语法填空中如何考数词？这四年广东高考中均没有考到数词的考点，但在以后可能会出现，主要可能考到的数词考点如下：1．inone'sfifties在某人几十多岁时Inmy________(ten),Ioftenwentforfishing.2．inthefifties在50年代Inthe________(80)ofthetwentiethcentury,ourcountrymadegreatprogress.teenseighties3．dozen,score,hundred,thousand等词语的用法：前面有具体的数词，用单数；没有具体的数词，用复数，且后面跟of短语(1)Itisreportedthatthefloodshaveleftabouttwo________(thousand)peoplehomeless.(2007·浙江)(2)Shewenttothebookstoreandbought________(dozen)ofbooks.(2006·北京)thousanddozens4．倍数的表达方式Peter'sjacketlookedjustthesameasJack's,butitcost________(two)asmuchashis.5．前后文有提示的情况下，表示“第几”的序数词Thentherecomethreeproblems.Thefirstiswhentosetoff.The________(two)ishowtogetthereandthelastiswhattodothere.twicesecond二、语法填空——代词和数词篇。阅读下面的短文，用适当的代词填空。ARobertwasapoorwelder.Emilygrewupinawealthyfamily.1.________day,Emilylost2.________wayinthestreet.RobertledthewayforEmilybecause3.________knewthepathwell.Emilyhesitatedbutmade4.________wayforward.Later,theyfellinlovewitheachother.TheirweddingtookplaceonJuly6lastyear.Robert'sparentscametoattendtheweddingbywayofLondonbutEmily'sparentsdidn't.Atthebeginningofthemarriage,Emilyputawedgeofwoodunderthedoortokeepitopenoneveryafternoon.Thensheweededinthegardenwhilewaitingfor5.________husband.ButforEmily,thenoveltyofmarriageworeoffsoon.OneherheherherShehadtoweavewebtoearnsomemoneybecauseRobert'swelfarewasn'tenoughtosupport6.________expenseatall.Herbootswerewornoutbutshecouldn'tbuy7.________pair.Emilyweptbittertearsoverherchoice.Shelostweightdaybyday.ShethoughtRobertgotinherwayandherstupidchoicegotinthewayofherfuture.Sheshouldleave8.________bywayofdivorce.Emilythoughtto9.________oftheseideasinhermind.Shebegantocomplain.HerwearyspeechwouldneverendevenRobertwaswearyafterhisday'swork.Herweaponswerehertears.Whenshewept,everyonehadtomakeway.Infact,RobertneverhurtEmilyinanyway.Inhismind,10.________wasinnowaytoblame.Inaway,itwashisfaultforgivingwaytohiswifeeverytime.Let'sseewhatwouldhappenintheend.theiranotherhimherselfsheBAtravelerdroveacartothecountryside.Halfwaythere,1.________ofhiscarwheelscameoff.Somegirlssmiledandwhisperedwitheachother.Thetraveler'sbrainwasinawhirl.Towhitewash2.________embarrassment,hesaidhelloto3.________.Thegirlsinvitedhimto4.________village.Whoevercamewouldbewelcome,whethertheyknowhimornot.Thetravelerhesitatedforawhilethensaid,“Whereveryougo,Ifollow.”Inthesmallvillage,somepeasantsweregrindingwheat.5.________otherswerewhitewashingahouse.The6.________weredrinking.Theyinvitedthetravelertojointhem,“Youcandrinkwhateveryouwant.Whataboutaglassofwhisky?It'swholesomedrinkforyou.Takewhicheverseat7.________like.”onehisthemtheirSomeothersyouItwasapoliteaswellasfriendlyinvitation.Thetravelerdrankonceinawhile,sohesatdownandasked,“WhatifIgetdrunk？”8.________answeredquickly,“Youcanstayovernighthere.”Thetravelergavealoudwhistleofgladness.Afterawhile,hedidgetdrunk.Thenextmorning,thepeasantslentthetravelerahorseandtheysaidhecouldcomewhenever9.________likes.Thetravelerappreciatedthemverymuch.Hehadneverdoneanythingforthem,whereastheyhaddoneeverythingforhim.Onthewhole10.________stayherewasquiteenjoyable.Thetravelerrodeonthehorse.Hecoulddriveacar;hecouldride
