数词专练
数词是表示数量多少或顺序先后的词。分为基数词和序数词。
（一）基数词
1. 表示数量多少的词是基数词，如：one, two, three等。
2. 数词的构成
1）从1－12分别由从one到twelve，12个各不相同的词表示。
one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve
2）从13－19均以后缀-teen结尾。
thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen
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。
twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
21 twenty-one 32 thirty-two 43 forty-three
4）整百数由1—9加hundred构成。
100 one (a) hundred 500 five hundred
5) 整百数和整十数之间由and连接，十位与个位之间要加连字符“-”。如果十位数为零，那就在百位和个位之间用and连接。
101 one hundred and two 245 two hundred and forty- five
6）千 thousand 百万 million 十亿 billion
Exercise:

2、序数词
序数词表示排列顺序，如first, second, third等。
构成规则：
1) 序数词第一、第二和第三为first, second和third,其他序数词的构成是在基数词后加th。例如：
2) fifth(第五)、 eigth (第八)、 ninth (第九)和twelfth (第十二)在拼法上有变化。first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, twelfth, thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, eighteenth,
3) 二十、三十等基数词变为序数词时,要把y变成ie再加-th。例如：
twentieth, thirtieth, fortieth, fiftieth, sixtieth, seventieth, eightieth, ninetieth
4) 基数词几十几变成序数词时,表示几十的数词不变,只把表示几的基数词变成序数词。
例如：
twenty-one → twenty-first forty-five → forty-
5) 第一百、第一千、第一百万、第十亿都是在基数词后直接加构成。例如：第一百
→hundredth第一千第一百万→millionth第十亿
6）.序数词的缩略形式是由阿拉伯数字加序数词的最后两个字母构成。例如：
7) 序数词前必须加定冠词the
The first time I came to China, I liked it very much.
我第一次来中国，我就非常喜欢这个国家。
第一总是比第二好。
She will choose the third. 她将选择第三。

3. 数词的应用
1）时刻的表示法
A、表示几点钟用基数词加可以省略的o'clock
5:00 读作 five o'clock 或 five
B、半点的表示法
表示半点钟时，用“钟点数+ thirty”或“half+ past +钟点数”表示
2: 30 two thirty / half past two
8:30 eighty thirty / half past eighty
C、“几点几分”的表示法
（1）用“钟点数+分钟数”表示
7：10 seven ten 9：40 nine forty
（2）分钟数在30分钟以内的，用“分钟数+ past +钟点数”表示，意为“几点过几分“
7：10 ten past seven 10:15 fifteen past ten / a quarter past ten
（3）分钟数超过30分钟的，用“（60-分钟数）+ to +下一个钟点数”表示，意为“差几分到几点”
10:40 twenty to eleven 2 : 45 fifteen to three / a quarter to three

小升初英语语法数词专项讲解 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。 a. 与of 短语连用，表示概数，不能与具体数目连用，如scores of people 指许多人; b. 在一些表示"一排"或"一组"的词组里; 如：They arrived in twos and threes. 他们三三两两的到达了。 c. 表示"几十岁"; d. 表示"年代"，用 in +the +数词复数; e. 在乘法运算的一种表示法里，如：3 x 5 = 15 Three fives is (are) fifteen. 序数词的缩写形式： first---1st second---2nd thirty-first---31st a. 主语+谓语+倍数(或分数)+ as + adj. + as I have three times as many as you. 我有你三倍那么多。 b. 主语+谓语+倍数(分数)+ the size (amount，length…) of… The earth is 49 times the size of the moon. 地球是月球的49倍。 c. 主语+谓语+倍数(分数)+ 形容词(副词)比较级+ than… The grain output is 8 percent higher this year than that of last year.

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

I've finished three-fifths of the words. 5. 有关倍数表示法 两倍用twice, 三倍以上用数词+times, 要注意倍数在句子的位置。 例：The door is three times the size of this. 6. 十位数字（个位为零）的基数词以复数形式出现时，表示年代、年龄 例：She is a good-looking woman in her forties. (forties 指40—49岁之间) 四．数词实练习题解析：
