数 词
英语数词表示数目或者顺序， 可分为基数词和序数词。
基数词表示数量，序数词表示顺序。
知识梳理：
提纲挈领，抓住重点和难点!
一、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， 13—thirteen 15—fifteen 18—eighteen.
3.20—90的整十位均以-ty结尾。
如：
sixty，ninety，但20，30，40，50，80较特殊， 20—twenty 30—thirty 40—forty 50—fifty 80—eighty.
4.十位数与个位数之间要加连字符号“-”，如：
28—twenty-eight，96—ninety-six.
5.百位和十位（若无十位则和个位）之间加and，如：
148—one hundred and forty-eight 406—four hundred and six.
6.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s。
如：
600—six hundred，8百万—eight million.
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”。
如：
2，510=two thousand five hundred and ten;84，296=eight-four thousand two hundred and ninety-six;274，350=two hundred and seventy-four thousand three hundred and fifty.
二、序数词的构成
序数词一般是以与之相应的基数词尾加-th构成，例如 fourth, tenth,但以下的这些基数词变为序数词时， 有特别之处。
1.one--- first, two --- second, three --- third, five --- fifth, nice --- ninth, twelve --- twelfth
2. 以ty 结尾的单词， 要先变y为I, 在加-eth. 例如：
thirty ---thirtieth, fifty ---fiftieth
3. 以one, two, three 等结尾的多位数词， 要将各位数变成序数词。
例如：
twenty-one --- twenty-first, one hundred and one --- one 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。
例如：
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。
三、数词的应用
1.时刻的表示：
小时、点钟、分钟、秒钟要用基数词

②“几点过几分 ”，≤30分钟”用介词past. 如：
7：
05—five past seven;7：
15—fifteen （a quarter）past seven;7：
30—half past seven.
③“差几分几点”用介词“to”。
如：
7：
40—twenty to eight;7：
45—fifteen（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：
05—seven o five;7：
15— seven fifteen.
2.年月日的表示
① 年份用基数词，如：
1999年—nineteen ninety-nine; 1900年—nineteen hundred; 2000—two thousand;1905—nineteen o five;
② 年用基数词，日用序数词。
如：

④ 如果编号的数词比较长，一般用基数词。

⑤ 电话号码，用基数词,如：
3855633—three eight five five（double five） six three three（double three）。
5.分数的表达
