1、中考总复习之,数词,大庄中学,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.基数词表示数目的多少构成方法如下: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“-”如:23twenty-t

2、hree 57 fifty-seven百位和十位之间要加and;如:127 one hundred and twenty-seven,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。如:3,678读作three thousand six hundred and seventy-eight2,468,723读作 two million four hundred six eight thousand seven hundred and twen

3、ty three,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:thousands of students,millions of trees.,二.序数词表示事物的先后顺序,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、。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,该名词一般要大写;序数词放到名词的前面,加定冠词。第一课 Lesson 1/the first lesson.Row 3/the third row(二)年、日、时刻表达方法。“年”用基数词,“日”用序数词,前要加定冠词。读的顺序是月日年。如:1990年5月2日读作:May the second,nineteen

5、 ninety。,“时刻”用基数词表达,同时要注意以下两点。,1.表示“整点”时,在基数词后加oclock;9:00 oclock.2.分钟小于或等于30分钟的,用“分钟数past钟点数”形式;分钟数大于30分钟的,用“到下一个钟点所差的分钟数to下一个钟点数”形式,也可以依次读钟点数和分钟数。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 six 5:45 读作:a quarter to six 6:15 读作:a quarter past s

6、ix,(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 boys1/2,1/4分别用 a half和a quarter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

9、确使用分数:分子在前用基数,分母在后用序数。分子大于一,分母用复数,分子与分母之间可以用连字符连起来也可以不用连字符,如two thirds或two-thirds;当分数修饰名词作定语时,后要跟of,如:two thirds of students 三分之二的学生 本题的选项中只有A项正确。,A,3.hundred,thousand,million,billion等单位数词,How many people will come to Beijing next year?Its hard to say,_ people,I think.(5分)A.million of B.millions of
