知识清单
表示数目多少或顺序先后的词叫数词.数词分为基数词和序数词.
1.基数词:表示数量的多少的词
(1)基数词的表达法(1~19除外)
①20~90之间表示“几十”的整十位数,如下表:
②21~99之间表示“几十几”的非整十位数,用“整十位数＋连字符(－)＋个位数”表示,如:twenty-fur 24;③100~900之间表示“几百”的整百位数,用“具体数字＋hundred”表示;④101~999之间表示“几百几(十几)”的非整百位数,用“百位数＋and+末(两)位数”表示,如:tw hundred and eight 208.
(2)基数词的基本用法
①表示年、月、日、年龄,如:twelve years ld 12岁;②表示人或物的数量,放在名词之前,如:three balls三个球;③表示顺序、编号等,放在名词之后,名词首字母要大写,如果基数词用英语单词表示,其首字母也要大写,如:Class Fur 四班;④表示价格、时刻、号码和计算等.
2.序数词:表示事物的顺序的词
(1)基数词变序数词(序数词的构成)
①一般情况下在基数词后加－th,如:six-sixth;②整十的序数词的构成是把对应的基数词词尾的y变为ie,再加－th,如:thirty-thirtieth;③两位或两位以上的基数词变序数词,只将个位数变序数词,如:ne hundred and sixty-five-ne hundred and sixty-fifth;④特殊变化的基数词1,2,3,5,8,9需单独记忆,如:ne-first.
(2)序数词的基本用法
①序数词前一般要加定冠词the表示顺序(有些词组中的序数词前没有冠词,如at first开始);②若序数词前有物主代词或名词所有格,则不再用定冠词the,如:Tm's third bk 汤姆的第三本书;③序数词前有时也可用不定冠词a/an,表示在原有基础上的“又一个,另一个”,如:I can have a secnd try.我可以再试一次.④表示编号时,用“the+序数词＋名词”,如:Lessn Five=the fifth lessn 第五课;⑤表示分数时,分子用基数词,分母用序数词,分子大于一,分母需加－s,如:three furths四分之三.
(3)序数词的缩写形式:由阿拉伯数字加上序数词的最后两个字母构成,如:first-lst第一.

例2根据提示,完成句子
(1)-Hw much is yur sweater?
-It csts me_______ (207) yuan.
(2)Last year, _______ (数百名)children went t the Christmas party.
【答案】(1)tw hundred and seven
(2)hundreds f
【思路解析】(1)句意:“你的毛衣多少钱?”“它花了我207元.”表示价格用基数词,207是“101~999”之间的非整百位数,用“百位数＋and+末(两)位数”表示.
(2)句意:去年,数百名孩子参加了这个圣诞晚会.在表示抽象数字时,成百的用hundreds f,类似的还有thusands f, millins f等.
例3单项选择
There are_______ days in a week. _______ day is Mnday.
【答案】D
【思路解析】句意:一周有七天,第二天是星期一.一周有七天,显然表示数量的多少,所以第一个空要填基数词;在西方文化中,往往把星期日作为一周的第一天,这样星期一就是第二天,要用序数词,且序数词前一定要加定冠词the.
走出误区
完成这道题,我们要注意两点:①在大多数人的思维中,都认为周一是一周的第一天,因此会错选为B项;②“序数词前必须加the”,这个知识点很多同学都会背,但做题时往往受汉语意思的影响而忽略了the.
