中考数词讲解及练习.doc

中考总复习之数词 努力学习是成功的种子,加油吧！中考考点： 1 基数词（ cardinal number） 2 序数词（ ordinal number ）数词:数词就是表示事物的数量和顺序的词，分基数词和序数词两种。一、基数词表示数量多少的词是基数词，如：one, two, three等。构成方法如下：1）从112分别由从one到twelve12个各不相同的词表示。2）从1319均以后缀-teen结尾。3）从2090的整十数词均以后缀-ty结尾。表示“几十几”时，个位和十位之间需加连字符，如twenty-one, thirty-two, forty-three等。4）数字的写法和读法：十位与个位之间要加连字符“-”；百位和十位之间要加and；三位数以上的数，从个位往前数，每三位数加一个逗号“，”，从后往前数的第一个逗号代表thousand,第二个逗号代表million,第三个逗号是billion，注意这几个词不能用复数形式，后也不能加and。5）表示具体、准确的数目时，hundred, thousand, million，score及dozen等数词后不能加-s, 如:five hundred, six thousand, seven million等。当hundred, thousand等数词与of连用，表示不具体、不准确的数目时，词尾须加-s。如： thousands of students, millions of trees .(考点) How many people will come to Beijing next year?
