1、中考总复习之,数词,张集中学 肖本军,努力学习是成功的种子,中考考试说明要求掌握 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
2、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等数词后不能加-s, 如:five hundred, six thousand, seven million等。 6）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： t
3、housands of students, millions of trees.,二.序数词,1）不规则变化，记住1-10的序数词。 2）以-ty结尾的表示“几十”的基数词，先把y变为i，再加-eth 3）表示“第几十几”时，十位数的“几十”仍用基数词，只把个位部分变成序数词就行了。 4）除上述情况外，均在词尾加-th，如ten tenth one hundred one hundredth 基数词变序数词顺口溜： 一、二、三，特殊记 f代替v和e 八去t，九去e 整十变y为ie 几十几变化个位就可以 末尾th别忘记,三. 数词的用法,（一）表示事物的编号 基数词放到名词的后边,该名词一般要大
4、写；序数词放到名词的前面，加定冠词。 第一课 Lesson 1/ the first lesson.

5、数和分钟数。7:20 twenty past seven或seven twenty. 3.注意两个特殊的表示时间的单位词：30分钟用half，15分钟用a quarter，如：6:30 读作：half past six5:45 读作：a quarter to six6:15 读作：a quarter past six,（三）分数的表达方法,表示分数时，分子用基数，分母用序数，分子大于1，分母用复数。分数修饰名词时，后用of短语。如： 1/3 one third of teachers 3/7 three sevenths of the boys 1/2, 1/4分别用 a half和a qua
6、rter表示。,（四）“基数词名词形容词”结构,“基数词名词形容词”只能用来放到名词前作定语。如： She is a 3-year-old girl. They live in a 7-storey-high building. 注：这种结构中名词不能用复数，同时只能作定语。用作表语时，不用连字符，名词有复数。如： Tony is 10 years old this year.
