中考英语专题复习数词

第第页2017中考专题复习——数词1.近几年中考对数词的考查主要是对基数词和序数词的构成及其用法上。日期、时间和分数也是中考考查的考点。题型将以选择题、词汇运用和完形填空为主。2.数词考查往往与其他知识点考查结合进行,如主谓一致等。3.预计2017对数词的考查重点仍然是基数词确数和概数的区分以及序数词拼写和应用。一、数词概述表示数目多少或是顺序先后的词叫数词。数词分为基数词和序数词。二、基数词表示数目多少的词是基数词。1.最基本的数词: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.基数词1~12是独立单词,所以我们必须逐个记忆。基数词13~19是个位数词的词干后加teen构成。其中thirteen,fifteen,eighteen变化不规则。基数词20~90是在十位数词后面加ty构成。基数词21~99是在十位数词后面加个位数词合成,中间加上连字符号“-”。如:21twenty-one;83eighty-three3.基数词101~999,先说“几百”,再加and,再加末尾两位数或末位数,基数词三位以上的数词,在百位与十位之间,一般要加连词“and”。4.英语中没有“万”和“亿”,万也用thousand来表示,亿也用million来表示,按十进位来推算。如:10000tenthousand100000000ahundredmillion67876sixty-seventhousandeighthundredandseventy-six5.在dozen,score,hundred,million,billion前如果有具体数字,它们不能加“s”;反之则须加“s”表示不确切的数量。如:twohundredpeople;thousandsofpeople。三、基数词的用法1.编号的事物用基数词Number1第1号Page11第11页Lesson28第28课Room123第123号房间案例①(2016·四川宜宾·1分)Inthistest,we’reaskedtowriteapassageofabout.
