中考总复习之数词

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。

? 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1-12分别由从one到twelve12个各不相同的 词表示。 ? 2)从13-19均以后缀-teen结尾。 ? 3)从20-90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: ? ⑴十位与个位之间要加连字符“-”; ? ⑵百位和十位之间要加and; ? ⑶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。

一.基数词

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
? 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 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o’clock; ? 9:00 o’clock. ? 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 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 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 is 10 years old this year. ? Tony is a 10-year-old boy.

比赛规则 1. 比赛共三个部分,基础抢答题 , 中考典型题和附加冒险题. 2. 回答问题时先举手, 回答正确根据题目的 难度得到相应的分数. 3. 哪组抢到问题了,可以集体回答,也可以有 组长指定人回答. 4. 举手必须在老师发出“Go”后,方可抢答. 加油哟!输了可要惩罚的哦……
