数词的讲解和练习
数词用法讲解及练习
数词I.定义与分类数词是指表示数目多少或顺序先后的词。
表示数目多少的数词叫基数词，如one, five, ten, thirty, sixty-five 等；表示顺序先后的数词叫序数词，如first, sixth, tenth, twenty-first 等。
数词用法相当于名词和形容词，在句中可用作主语、宾语、表语、定语、同位语等。
II. 基数词1. 英语中没有“万”这个读数单位，要表示汉语中的“万”，英语需借用thousand一词，如“一万”用“十个千”表示(ten thousand)，“十万”用“一百个千”表示(one hundred thousand)。
2. 用作基数词单位的hundred, thousand, million, billion 通常不带复数词尾-s，但若用于表示数百、数千、数百万这样的泛指，则用复数。
如：About two thousand people died in the earthquake. 大约有两千人在地震中丧生。
Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。
3. 表示整十的基数词用复数形式可以表示人的大约岁数或年代。
如：He is in his early twenties. 他才二十出头(from 。
This took place in the 1930s. 这事发生在20世纪30年代。
III. 序数词1. 许多序数词是由相应的基数词后加词尾-th构成的，如four / fourth，six / sixth，ten / tenth，sixteen / sixteenth，但是nine变为序数词是ninth，而不是nineth。
2. twentieth, thirtieth, fortieth 等表示整十的序数词，由相应的基数词将词尾y改为ie，再加-th 构成。
3. first, second, third 通常可缩写为1st, 2nd, 3rd。

知识讲解一、数词讲解(一)数词的概念：表示数目多少或顺序多少的词叫数词，数词分为基数词和序数词。
表示数目多少的数词叫基数词；表示顺序的数词叫序数词。
(二)基数词的表示法1、1—12的基数词是独立的单词：one，two，three，four，five，six，seven，eight，nine，ten，eleven，twelve2、13—19的基数词以-teen结尾fourteen，seventeen等，但13，15，18较特殊，13—thirteen 15—fifteen 18—eighteen。
3、20—90的整十位均以-ty结尾。
20—twenty、30—thirty、40—forty、50—fifty、80—eighty、ninety—904、十位数与个位数之间要加连字符号“-”28twenty-eight，96 ninety-six5、百位和十位（若无十位则和个位）之间加and148—one hundred and forty-eight、406—four hundred and six6、hundred（百），thousand（千），million（百万），billion（十亿）等前面即使有具体的数词，也不能在它们的后面加s600—six hundred、8百万—eight millionhundred，thousand，million用复数形式修饰名词时要用“of＋复数名词”数以百计的年轻人hundred s of young people；数以千计的书thousand s of books注意：hundreds of ／thousands of／millions of ＋复数名词，其前面不能加具体的数词。
7、1000以上的数字，从后往前数每三位加一个逗号“，”第一个逗号前为千（thousand），第二个逗号前为百万（million），第三个逗号前为billion （十亿）。
英语中无“万”这个词，我们可以用“几十个千（thousand）”表示几万，“几百个千（thousand）”表示“几十万”。
2，510＝two thousand five hundred and ten；84，296＝eighty-four thousand two hundred and ninety-six；274，350＝two hundred and seventy-four thousand three hundred and fifty。
翻译成英文的时候，十亿，百万，千之间直接连接，不用and，只有百和十位或个位之间用and。
8、基数词＋单数名词＋形容词构成合成形容词。
一个五岁的女孩a five-year-old girl.女子800米接力girls'800-metre relay race长河长6，300米The Changjiang River is 6，300-kilometre-long．（三）序数词的表示法1.以下是最基本的序数词：first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth eleventh, twelfth, thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, eighteenth, nineteenth, twentieth, thirtieth, fortieth, fiftieth, sixtieth, seventieth, eightieth, ninetieth.【注意】①许多序数词是由相应的基数词后加th构成的，如：four / fourth，six / sixth，ten / tenth，sixteen / sixteenth，但是nine变为序数词是ninth，而不是nineth。
②twentieth, thirtieth, fortieth 等表示整十的序数词，由相应的基数词将词尾y改为ie，再加th 构成。
③first, second, third 通常可缩写为1st, 2nd, 3rd。
凡是以th结尾的序数词可缩写为“基数词+th”：4th, 5th, 9th, 11th, 60th, 128th等。
2.非整十的多位数，将个位数变成序数词即可：twenty-first(第21)，ninety-ninth(第99)，three hundred and sixty-fifth(第365)等。
3.hundred, thousand, million 等序数词形式为hundredth, thousandth, millionth口诀：1，2，3特殊记， one-first two-second three-thirdf来把ve代替， five-fifth整十ie来把y代替， twenty-twentieth, thirty-thirtieth8去t, 9去e， eight-eighth，nine-ninth遇到几十几，只变各位就可以4.序数词前使用冠词应注意的两点a. 序数词前通常要用定冠词It’s the third time I’ve been here. 这是我第三次来这儿。
The second is better than the first. 第二个比第一个好。
【注意】①序数词用作副词时也通常不用冠词：He came first. 他先来。
I’ll have to finish my homework first. 我得先把作业做完。
②有些习语中的序数词前没有冠词：at first首次first of all 首先不at first sight 次first③但若序数词前用了物主代词或名词所有格，则不能再用定冠词：his second wife 他的第二个妻子Tom’s third book 汤姆的第三本书b. 序数词前有时可用不定冠词，表示次第在原有基础上的增加：A second student stood up. 又一个(第二个)学生站了起来。
I want to read the book a third time. 这本书我想读第三次。
序数词前用定冠词和不定冠词的区别在于，定冠词表特指，不定冠词表泛指I like the third girl. 我喜欢第三个女孩。
(至少有三个女孩供选择，特指)I saw a third girl. 我又看见了第三个女孩。
(暗示原来已看见两个，这已是第三个) （四）分数和百分数1. 分数（1）分数的分子用基数词，分母用序数词。
one fifth五分之一one tenth十分之一（2）当分子大于1时，分母用序数词的复数。
two thirds三分之二five eighths八分之五（3）当分子是1时，可以用one也可以用a.如：a second = one second a third = one third（4）当分母是2和4时，分别可以用half和quarter代替。
a half二分之一three quarters四分之三2. 百分数百分数用percent表示。
forty percent百分之四十（40%）three percent百分之三（3%）3. 分数、百分数与主谓一致分数、百分数的考查往往和主谓一致相联系。
当分数、百分数修饰可数名词的复数时，谓语动词用复数形式；当分数、百分数修饰不可数名词时，谓语动词用单数形式。
如：Eighty percent of the students in our school come from Henan.我们学校百分之八十的学生来自河南。
Three fourths of the students in my class are interested in English.我们班四分之三的学生对英语感兴趣。
Two thirds of the water on the earth is sea water.地球上三分之二的水是海水。
（五）倍数的表示法1. 表示“几倍大小（长短；数量）”，由“倍数+ the size（length，amount……）”结构组成。
如：The earth is forth-nine times the size of the moon.2. 表示“……比……大几倍”，由“倍数+形容词（副词）比较级+ than +被比较部分”结构组成。
如：This box is three times bigger than that one.3. 表示“……是……倍”，由“倍数+ as +形容词+ as +被比较部分”结构组成。
如：Our factory is twice as big as theirs.课堂练习一、单词百变（1）Today is his ______(twenty) birthday.（2）Let’s go to see the pandas _____(one)（3）December is the ______ month of the year.
