第第頁2017中考專題復習——數(shù)詞1.近幾年中考對數(shù)詞的考查主要是對基數(shù)詞和序數(shù)詞的構成及其用法上。日期、時間和分數(shù)也是中考考查的考點。題型將以選擇題、詞匯運用和完形填空為主。2.數(shù)詞考查往往與其他知識點考查結合進行,如主謂一致等。3.預計2017對數(shù)詞的考查重點仍然是基數(shù)詞確數(shù)和概數(shù)的區(qū)分以及序數(shù)詞拼寫和應用。一、數(shù)詞概述表示數(shù)目多少或是順序先后的詞叫數(shù)詞。數(shù)詞分為基數(shù)詞和序數(shù)詞。二、基數(shù)詞表示數(shù)目多少的詞是基數(shù)詞。1.最基本的數(shù)詞:1~20:one;two;three;four;five;six;seven;eight;nine;ten;eleven;twelve;thirteen;fourteen;fifteen;sixteen;seventeen;eighteen;nineteen;twenty;30thirty;40forty;50fifty;60sixty;70seventy;80eighty;90ninety;100ahundred;1000athousand;1000000amillion;1000000000abillion2.基數(shù)詞1~12是獨立單詞,所以我們必須逐個記憶?；鶖?shù)詞13~19是個位數(shù)詞的詞干后加teen構成。其中thirteen,fifteen,eighteen變化不規(guī)則?；鶖?shù)詞20~90是在十位數(shù)詞后面加ty構成?；鶖?shù)詞21~99是在十位數(shù)詞后面加個位數(shù)詞合成,中間加上連字符號“-”。如:21twenty-one;83eighty-three3.基數(shù)詞101~999,先說“幾百”,再加and,再加末尾兩位數(shù)或末位數(shù),基數(shù)詞三位以上的數(shù)詞,在百位與十位之間,一般要加連詞“and”。4.英語中沒有“萬”和“億”,萬也用thousand來表示,億也用million來表示,按十進位來推算。如:10000tenthousand100000000ahundredmillion67876sixty-seventhousandeighthundredandseventy-six5.在dozen,score,hundred,million,billion前如果有具體數(shù)字,它們不能加“s”;反之則須加“s”表示不確切的數(shù)量。如:twohundredpeople;thousandsofpeople。三、基數(shù)詞的用法1.編號的事物用基數(shù)詞Number1第1號Page11第11頁Lesson28第28課Room123第123號房間案例①(2016·四川宜賓·1分)Inthistest,we’reaskedtowriteapassageofabout.
