一些特殊形式。阿拉伯數(shù)字基數(shù)詞序數(shù)詞序數(shù)詞縮寫1onefirst1st2twosecond2nd3threethird3rd5fivefifth5th8eighteighth8th9nineninth9th12twelvetwelfth12th20twentytwentieth20th21twenty-onetwenty-first21st22twenty-twotwenty-second22nd23twenty-threetwenty-third23rd其他序數(shù)詞的構(gòu)成：幾十幾及以上的序數(shù)詞，其中十位數(shù)或百位數(shù)、千位數(shù)等用基數(shù)詞，只有個位數(shù)才用序數(shù)詞。如:128th:onehundredandtwenty-eighth752nd:sevenhundredandfifty-second2．hundred，thousand，million的序數(shù)詞均在基數(shù)詞后加th構(gòu)成，即hundredth，thousandth，millionth。四、數(shù)詞的應(yīng)用1.百分比的構(gòu)成1.百分比的構(gòu)成基數(shù)詞+percent+of+名詞/代詞如：Twentypercentofthemilkisdrunkup.小數(shù)點前的整數(shù)按基數(shù)詞的規(guī)則表示，小數(shù)點讀作point，2.小數(shù)的構(gòu)成數(shù)點后的數(shù)字按其數(shù)字直接讀出來。2.小數(shù)的構(gòu)成如：13.56讀作thirteenpointfivesix。3.分數(shù)的構(gòu)成分子用基數(shù)詞，分母用序數(shù)詞；若分子大于一，分母的序數(shù)3.分數(shù)的構(gòu)成詞要用復(fù)數(shù)形式。如：1/3讀作onethird;2/5讀作twofifths數(shù)詞的應(yīng)用數(shù)詞的應(yīng)用4.倍數(shù)的構(gòu)成一倍once，兩倍用twice/double,三倍及三倍以上用4.倍數(shù)的構(gòu)成“基數(shù)詞+times”。如：threetimes,fourtimes等。5.年、月、日表示法5.年、月、日表示法年份用基數(shù)詞，日期用序數(shù)詞，其順序常用“月、日、年”。如：2009年11月15日；November15(th),2009或15（th）November,2009;讀作November(the)fifteenth,twoThousandandnine.6.編號表示方法6.編號表示方法冠詞；基數(shù)詞位于名詞后。如：LessonFive/thefifthlesson第五課 五、倍數(shù)表示法1.倍數(shù)用在形容詞原級的第一個as前面。如：Ihavetwiceasmanybooksasyoudo.我的書是你的書的兩倍。2.倍數(shù)用在表示度量的名詞前。如：Theearthis49timesthesizeofthemoon.地球是月球的49倍大大3.詞或副詞的比較級或by+倍數(shù)放在比較級后。Thisbuildingistwicehigherthanthatone.這個建筑物比那個建筑物高兩倍。約數(shù)表示法1．用ten，dozen，score,hundred，thousand，million等數(shù)詞的復(fù)數(shù)加of短語來表示幾十、幾百、上千、上萬、幾百萬等約數(shù)的概念。2.用lessthan,under,below，orless，almost，nearly，upto。等來表示小于或接近某數(shù)目。3.用morethan,over,above,beyond，ormore等來表示多于某個數(shù)目。4.用or，orso,about，around，some，moreorless等表示在某一數(shù)目左右。5.用from...to,between...and表示介于兩個數(shù)飼之間。如：1．Iboughtdozensofpencilslastyear.去年我買了幾十支鉛筆。2.Howcanyoufinishyourhomeworkinlessthanhalfanhour?你怎么能在半個小時內(nèi)就完成你的作業(yè)呢？3．Ourschoolhasahistoryofmorethansixtyyears.我們學(xué)校有60多年的歷史。4．Thedoctorspentfourorfivehoursperformingtheoperation.那醫(yī)生花了四五個小時做這個手術(shù)。5.Iwillbebackintwot。threeweeks.我兩到三周后就回來。七、基數(shù)詞變序數(shù)詞口訣：基變序，有規(guī)律，末尾加上th基變序，有規(guī)律，末尾加上th；一、二、三，特殊記(first,second,third）；八加h(eighth)，九去e(ninth)，ve要用f替（fifth;twelfth)；以y結(jié)尾變ie，后跟th莫忘記（如：thirtieth,fiftieth)；若想表示幾十幾，只變個位就可以。如：twenty-first,forty-ninth)?；A(chǔ)練習(xí)I.根據(jù)給出的數(shù)字分別寫出其相應(yīng)的英文形式。1.11___________2.15_____________3.19_______________4.28________________5.40____________6.67________________7.100_____________8.1000___________________9.1000000____________10.9th________________11.10th____________12.12th_________________13.13th______________14.14th______________15.20th_____________16.23rd_______________17.31st__________18.52nd___________________-II．用適當?shù)挠⒄Z數(shù)詞完成下列句子。1.Summeristhe___________seasonofayear.2.Wednesdayisthe___________dayofaweek.3．Thirtyis__________ofsixty,4.Children'sDayisonJune____________eachyear.5.Letter"I"is___________letterinthealphabet(字母表)．6.Thereare__________monthsinayear.7．Mysisterisjust20.Todayisher____________birthday.8.Thirtyplusninety-threeis____________.III．將下列詞組和句子譯成英語。1．十二把傘__________________2．二十個蘋果____________________3．十四輛公交車___________________4．四十間房子__________________5．十九件禮物_________________6．二千五百八十七名學(xué)生_________________7.60億8000萬人口___________________________8．成百上千的顧客______________________9．第一謀_____________________10.百分之三十的水__________________________11.百零五點三二______________________________12.三分之二的書____________________13.在20世紀80年代___________________14.2009年3月18日____________________________15.這個洞是那個洞的三倍深。_______________________________16.現(xiàn)在，他們在九號房間開會。_______________________________IV.根據(jù)括號內(nèi)的詞，在空白處填入恰當?shù)脑~。1.Ithinkthe___________lessonisthemostinterestingoneinthebook.(twelve)2.Myfatherisnowinhis_________,butheisstilltakingsomecomputercourses.(fifty)3.Thereare___________ofpeoplewhoarelosingjobsandtheyarewonderingwhattodo.(thousand)4.Ihavetried_________(兩次),butI'lltry_____________（再一次）．5．Iliveon______（第六大街），butworkfarfromit．6.Harryhasjustfinishedwritingan______________（八百字）composition.7.ItissaidthatthegravityontheMarsisonlyabout______________（三分之一）ofthegravityontheearth.8.Chinaisalmost___________(two)thesizeofMexicoinarea.第二課時難疑拓展疑難點一序數(shù)詞前加定冠詞時表示順序，意為“第幾”。如：Iwasthefirsttocomehere.我是第一個來這兒的人。序數(shù)詞前加不定冠詞時表示“又一，再一”。如：Ihavefailedtwice，butlwanttohaveathirdtry.我失敗兩次了，我想再試一次。疑難點二“of+the+基數(shù)詞”表示范圍。如：twothirdsoftheten十個中的三分之二。疑難點三表示年代用“in+the+數(shù)詞的復(fù)數(shù)形式”。如：inthe1990s或inthe1990's在20世紀90年代。表示某人的年齡階段用“in+物主代詞十數(shù)詞的復(fù)數(shù)形式”。如：inhis20s在他二十幾歲時；inher30s在她三十幾歲時。疑難點四“數(shù)詞十名詞十形容詞”作定語時，中間要用連字符，而且中間的名詞只用單數(shù)形式。如：afive-year-oldgirl，一個五歲的女孩；a15-minute-longwalk一段十五分鐘的步行路程。疑難點五“數(shù)詞+hundred/thousand/million/billion+名詞復(fù)數(shù)”表示具體的數(shù)量；如：twothousandstudents;fourhundredgirls等?！皌ens/dozens/scores/hundreds/thousands/millions/billions+of+名詞復(fù)數(shù)”表示“許多”。如：thousandsoftrees;tensofhundredsofhorses等。疑難點六表示時刻時，如果在30分鐘以內(nèi)，用past，如8：15讀作fifteenpasteight或aquarterpasteight;如果超過30分鐘，則用to，如8：40讀作twentytonine。能力提升I.單項選擇。()1.____________ofthewarmwateralreadybeenusedup.A.Two-third;hasB.Two-third;haveC.Two-thirds;hasD.Two-thirds;have()2.__________thestudentsintheprimaryschoolisaboutthreethousand,and_________ofthemaregirls.A.Anumberof;twothirdB.Thenumberof;twothirdsC.Anumberof;twothirdsD.Thenumberof;twothird()3.----Comeandseemein_______________.-----Withpleasure.That'swhatI'mexpecting.A.twoorthreedays.B.twoorthreeday'stimeC.twoorthreedays'timeD.twoorthreeday's()4.Dick,itisthe_________timein________daysthatyou'vemadethesamemistake.A.two;threeB.second;threeC.two;thirdD.second;third()5.-----Howmanyteachersarethereinyourschool?----______________butI'mnotsure.A.HundredsB.HundredC.HundredsofD.Onehundred()6.Ittookme_________tofindoutthekeytothedrawer.A.oneandhalfhoursB.oneandahalfhoursC.oneandahalfhourD.oneandhalfhour()7.Wecansee____________starsintheskyatnight.A.tenofthousandofB.tensofthousandofC.tenofthousandsofD.tensofthousandsof()8.Onedayonthemoonis____________.A.twoearthweeklongB.twoearthweekslongC.twoearthweekslongerD.twoearthweekslength'()9.Shewenttothecountryside_________.A.inthemorningatnineonJunefirst,1968B.onJunefirst,1968inthemorningatnineC.atnineinthemorningonJunefirst,1968D.onJunefirst,1968atnineinthemorning()10.John
