第三章數(shù)詞

數(shù)詞歸納小結(jié)：1．掌握基數(shù)詞、序數(shù)詞、分?jǐn)?shù)詞、倍數(shù)、百分?jǐn)?shù)、年月日、鐘點(diǎn)、年齡、序號(hào)的基本用法。2．掌握不定數(shù)量詞、約數(shù)詞的表達(dá)方法。數(shù)詞在各個(gè)題項(xiàng)中，單選、閱讀、聽力、寫作中發(fā)揮著很強(qiáng)的作用，往往用以說(shuō)明事實(shí)的精確性和可信性。數(shù)詞是由兩大部分構(gòu)成的，即基數(shù)詞和序數(shù)詞，而其他數(shù)字表示法如分?jǐn)?shù)、小數(shù)等均由這兩大部分的不同組合構(gòu)成。一、基數(shù)詞：表示數(shù)目的詞為基數(shù)詞，它的構(gòu)成如下表：范圍特點(diǎn)實(shí)例1~12無(wú)規(guī)律one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve13~19以teen為結(jié)尾thirteen,fourteen,fifteen,sixteen,seventeen,eighteen,nineteen20~90以ty結(jié)尾twenty,thirty,forty,fifty,sixty,seventy,eighty,ninety21~99十位與個(gè)位之間要加連字符“-”twenty-five,sixty-five,ninety-nine101~999百位與十位之間通常用andthreehundredandtwenty-five（美語(yǔ)中常將and省略）千以上6275—sixthousandtwohundredandseventy-five；1200—twelvehundred二、序數(shù)詞：表示順序的數(shù)詞為序數(shù)詞，它的構(gòu)成如下表：范圍特點(diǎn)實(shí)例1~19各基數(shù)詞尾加th其中七個(gè)例外：first,second,third,fifth,eighth,ninth,twelfth,其余，如：four—fourth,six—sixth,nineteen—nineteenth20,30~90把y變i后加ethtwentieth,fortieth,ninetieth21以后多位數(shù)最后一個(gè)數(shù)用序數(shù)詞，其余用基數(shù)詞21st—twenty-first,110th—onehundredandtenth三、數(shù)詞的用法（一）.英語(yǔ)中年月日、點(diǎn)鐘、序數(shù)詞、分?jǐn)?shù)詞、算式列表示例英語(yǔ)表示法2001.6.30June30,2001/30June,2001/30thJune,20017：25seventwenty-five/twenty-fivepasteven12:54twelvefiftyfour/sixtoone9:15ninefifteen/aquarterpastnine2:30twothirty/halfpasttwo21:50twenty-onefifty/9:50p.m.第21twenty-first第123onehundredandtwenty-third1/2ahalf22/5twoandtwo-fifths20%20percent第七路公共汽車BusNumberSeven第201房間Room201人民路153號(hào)153RenminRoad4+8=12Fourpluseightistwelve.11-7=4Elevenminussevenisfour.6×5=30Sixtimesfiveisthirty.20÷5=4Twentydividedbyfiveisfour.A＞BAismorethanB.A＜BAislessthanB.A≈BAapproximately(近似地,大約)equalstoB.A≠BAisnotequaltoB.（二）約數(shù)表示法列表含義英語(yǔ)表達(dá)例句大于某數(shù)morethanHehaslivedhereformorethantwentyyears.overSheisoverfifty.ormoreThere’rethirtypeopleormoreinthemeeting-room.小于某數(shù)lessthanIhavelessthan(notmorethan)fiftydollars.underChildrenundersevenarenotallowedtoenter.belowHewouldnotsellitforbelowahundredfiftydollars.orlessThecoatmightcosthimsixtydollarsorless.大約（某數(shù)）nearlySheisnearlyfiftynow.almostIt’salmostthreeo'clock.uptoUptotenmencansleepinthistent.orHespentfourorfivedayswritingthearticle.orsoThedistanceistwentymilesorso.aboutIvisitedthatvillageaboutthreeyearsago.someTheirteamhassomefourorfiveplayers.moreorlessThecontainercanholdmoreorlesstwentypoundsofwater.around/roundLet'smakeitround/aroundeighto'clock.（三）不定數(shù)量詞“多”的表示法列表被修飾名詞的數(shù)英語(yǔ)表達(dá)漢譯修飾可數(shù)名詞dozensof幾十、許多scoresof許多many,agood(great)many,manya(修飾單數(shù)可數(shù)名詞)許多、大量hundredsof數(shù)以百計(jì)thousandsof,thousandsuponthousandsof成千上萬(wàn)millionsof數(shù)百萬(wàn)billionsof億萬(wàn)修飾不可數(shù)名詞much,agreat(good)dealof,alargeamountof,largeamountsof許多、大量可同時(shí)修飾可數(shù)名詞和不可數(shù)名詞alotof/lotsof,plentyof,alargequantityof,largequantitiesof許多、大量【強(qiáng)化練習(xí)】I.單項(xiàng)選擇1.Iwasborn_______. A.onJuly3rd,1981

B.inJuly3,1981 C.onJuly3,1981

D.inJuly3rd,1981

在具體日期前要用介詞on，表示日期的數(shù)詞也要用序數(shù)詞。

2.Mr.Smith_______metobuyseveral_______eggsforthedinner.(2005年上海)

A.asked,dozen

B.suggested,dozensof C.had,dozen

D.persuaded,dozensof

several修飾數(shù)詞時(shí)，后面的數(shù)詞用單數(shù)。asksb.todosth.叫……做某事。persuadesb.todosth.說(shuō)服某人做某事。

AA3.Itisreportedthatthefloodshaveleftabout_______peoplehomeless.(2007年浙江) A.twothousand B.two-thousands C.twothousands D.twothousandsof

當(dāng)表示整數(shù)的數(shù)詞被基數(shù)詞修飾時(shí)用單數(shù)形式，例如，twohundred,threemillion等等。除非表示籠統(tǒng)才用復(fù)數(shù)，例如hundredsof,thousandsof,dozensof等等。4._______ofthelandinthatdistrict_______coveredwithtreesandgrass.(2006年上海) A.Twofifth,is B.Twofifth,are C.Twofifths,is

D.Twofifths,are

分?jǐn)?shù)的表達(dá)方法，如果分子大于一，分母就要用復(fù)數(shù)形式，本題的主語(yǔ)應(yīng)該是整塊的land，因此看做是一個(gè)整體，后面謂語(yǔ)動(dòng)詞用單數(shù)。AC5.Theheroofthestoryisanartistinhis_______. A.thirtiethB.thirtyC.thirty’sD.thirties

某人幾十歲時(shí)的表達(dá)法用inone’s+數(shù)詞的復(fù)數(shù)形式。

表年代用inthe+年分，可以在年份直接+s，或用’s兩種方式。例如：inthe1840s/inthe1840’s。DD7.Southoftheequator,81%ofthesurfaceoftheearth_______water.

A.is B.are C.was D.were

本題考查分辨主語(yǔ)的能力，地球上81%的表面都是水，雖然前面說(shuō)到有81%，但地球的表面我們要看作是一個(gè)整體，謂語(yǔ)動(dòng)詞用單數(shù)。8.You'llhavetospend_______writingyourreporthere.

A.onedayortwodays B.onedayortwo C.adayortwo D.twodaysorone

表示一兩天我們可以用oneortwodays=adayortwo。

AC9.Thisriveris_______thatone. A.asthreetimeslongasB.thethirdtimeas C.threetimesthelengthofD.threetimeslonger

倍數(shù)修飾比較級(jí)要放在比較級(jí)的前面，本題沒有出現(xiàn)than，因此不選D。10.Americanseat_______vegetablesperpersontodayastheydidin1910.(2002年上海春季) A.morethantwiceB.astwiceasmany C.twiceasmanyasD.morethantwiceasmany

本題也是考查倍數(shù)的表達(dá)法，倍數(shù)要放在前面，因后面已經(jīng)出現(xiàn)as，因此選項(xiàng)C就不能選。
