初中英语数词讲解及专项练习
一、定义：表示数目或顺序。
二、分类：分为基数词和序数词两种。表示数目或数量多少
的词叫基数词；表示数目顺序的词叫序数词。
三、基数词的构成：1）1-12的基数词是独立的单词，即：
one，two，three，four，five，six，seven，eight，
nine，ten，eleven，twelve。2）13-19的基数词以-teen结尾。如：
fourteen，seventeen等，但13，15，18较特殊，
13fifteen,18twenty,30forty,50eighty。4）位数与个位数之
间要加连字符号"-"，如：28-twenty-eight，96-ninety-six。
5）百位和位（若无位则和个位）之间加and，如：148four hundred and six 6）hundred（百），thousand（千），
million（百万），billion（亿）等前面即使有具体的数词，several, some, many也不能在它们的后面加-s。如：six hundred， eight million。如果表示不确定数目时，用hundreds of /thousands of /millions of /billions of +名词复数,前面不能再加数字。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（亿）。英语中无“万”这个词，我们可以用"几个千（thousand）"表示几万，"几百个千
（thousand）"表示"几万"。如：2，510＝two thousand five hundred and ten84，296＝eighty-four thousand two hundred and ninety-six274，350＝two hundred and seventy-four thousand three hundred and fifty。
四、序数词的构成：1）序数词一般是以与之相应的基数词尾加-th构成，如：
fourth, tenth,但以下的这些基数词变为序数词时，有特别之处。Onesecond, threefifth, ninetwelfth2）以_ty 结尾的单词，要先变y为i, 在加-eth、。如：thirtyfiftieth3）以one, two, three 等结尾的多位数词，要将个位数变成序数词。
如：
twenty-oneone hundred and first 注意：
序数词前常用定冠词，有时还可以用不定冠词 a/an 则表示"又一 "的意思。（没有具体范围的限制）如：
Mr、 Brown has a second car、布朗先生另外还有一辆车。 He has tried a second time、他又尝试了一次。
五、数词的应用1）时刻的表示：小时、点钟、分钟、秒钟要用基数词。
①“几点钟”用基数词加oclock。oclock 可省略。如：5点钟-five（oclock）
②“几点过几分”，≤30分钟"用介词past。如：7：15half past seven
③“差几分几点”用介词"to"。如：7：40fifteen / a quarter to eight 。
④日常生活中的时间读法常常简化，直接按基数词的顺序读。如：7：05seven fifteen。2）年月日的表示：①年份用基数词，如：1999年nineteen hundred2000年nineteen o five；
②年用基数词，日用序数词。如：1998年6月8日写作：June8，1998；读作：June the eighth， nineteen ninety-eight或the eighth of June， nineteen ninety-eight。3）世纪、年代表示法，如：（在）90年代 (in)
the nineties（在）19世纪 (in)
the nineteenth century（在）18世纪30年代 (in)
the1730s或in the1730s 4）编号的表示：①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。L esson1/ the first lesson第一课 Row3/ the third row 第三排②Bus No、3＝the No、3bus3路公共汽车。③表示住所时不用No、如：
Room302读作：room three o two302房间。④如果编号的数词比较长，一般用基数词。如：Page457第457页。⑤电话号码，用基数词，如：-three eight double five six double three。5）分数的表达：分子用基数词，分母用序数词，分子大于"1"，分母则加"s"。如：1／3 one third2／3two thirds 1／2 a / one half1／4one fourth或a/ one quarter3／4 three
fourths或three quarters 6）表示有小数的词用基数词，如：
5、5 five point five
12、135 twelve point one three five 7）表示百分数，如：
5℅：five percent 0、8℅ zero point eight per cent 注意：分数、百分数与主谓一致当分数、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：
EightypercentofthestudentsinourschoolcomefromHenan、我们学校百分之八的学生来自河南。T hreefourthsofthestudentsinmyclassareinterestedinEnglish、我们班四分之三的学生对英语感兴趣。T wothirdsofthewaterontheearthisseawater、地球上三分之二的水是海水。

式，如：in his thirties 在他三几岁时④ 倍数的表达：一倍用once，两倍用 twice，两倍以上用基数词＋times。如：five times5倍补充：倍数的表示法：
1、表示“几倍大小（长短；数量）”，由“倍数+thesize （length,amount width age height、）+of ”结构组成。如：Theearthisforth-ninetimesthesizeofthemoon、地球的大小是月亮的四九倍。

▲掌握分数、时间、日期的表达法。 【复习要点】 （一）基数词 基数词用来表示数目，或者说表示数量的词叫基数词。最基本的基 1 one 11 eleven 100 a hundred 2 two 12 twelve 20 twenty 1000 a thousand 3 three 13 thirteen 30 thirty 1，000，000 a million 4 four 14 fourteen 40 forty 10，000，000 ten million 5 five 15 fifteen 50 fifty 100，000，000 a hundred million 6 six 16 sixteen 60 sixty 1，000，000，000 a billion 7 seven 17 seventeen 70 seventy 8 eight 18 eighteen 80 eighty 9 nine 19 nineteen 90 ninety 10 ten 说明： 1．13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen 和fifteen。 2．20—90由个位数加后缀-ty构成，注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。 3．其它非整十的两位数21—99是由整十位数加连字符“-”，再加个位数构成。如：81 eighty-one。 4．101—999的基数词先写百位数，后加and再写十位数和个位数。如：691 six hundred and ninety-one。 5．1000以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。 如：5893 five thousand eight hundred and ninety-three。在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand（千）和million（百万）来表达，其换算关系为：1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。 6．多位数的读法： 1）1000以上的多位数，要使用计数间隔或逗号“，”。即从个位起，每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand（千），第二个间隔或逗号前是million（百万），第三个间隔或逗号前是a thousand million或a billion(十亿)。 2）每隔三位分段以后就都成了101—999。读的时候十位数（或个位数）的前面一般要加and。如： 888，000，000读作：eight hundred and eighty-eight million。 基数词的用法： 1. 基数词在句中的作用 基数词的作用相当于名词和形容词，在句中可作定语、主语、宾语（介宾）、表语、同位语等。 例如：Three and five is eight. 3+5=8 （作表语）How many oranges do you want?你要多少桔子？ I want eight. 我要八个。（作宾语）There are eight boats in the lake. 湖里有八条小船。（作定语） 2．Hundred, thousand, million, dozen, score这些词前面如有表示具体数字的词，它们不能加“s”,反之则须加“s”, 并要与of短语连用。例如：three hundred people, five thousand years； thousands of people, hundreds of students, thousands of trees （二）序数词 表示顺序的词，叫序数词。序数词用来表示数词顺序。除特殊情况外，序数词一般都由相应的基数词加后缀-th构成。 请见下表： 第一到第十第十一到第十九第二十以上 first eleventh twentieth
