【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。
最基本的基数词如下表所示。
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。

知识点1:基数词和序数词(一)基数词——从1数到n阿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。
(二)序数词——由基数词转变而来,表示“这是第n个”1.口诀巧记基数词变序数词:“一、二、三,特殊记,八去“t”,九去“e”,“ve”要用“f”替,见“y”变成“i”和“e”,词尾加上“th”,若是遇到几十几,只变个位就可以。
”第一、第二、第三分别:first,second,third,eight—eighth nine—ninth,five—fifth,twelve—twelfth,twenty—twentieth,forty—fortieth,twenty-five—twenty-fifth。
2其余情况均在基数词后加th。

1、第一类:one 一two 二three 三four 四five 五six 六seven七eight 八nine 九ten 十eleven 十一twelve 十二这一类共计十二个单词,在结构上与其他的基数词相比较是特殊的,就象不规则的动词一样,要求逐个的硬背下来,这对学好其他的基数词和序数词都是及其重要的。
2、第二类:thirteen 十三fourteen 十四fifteen 十五sixteen 十六seventeen十七eighteen十八nineteen十九这一类基数词共有七个。
它们在结构上有两个特点:一是在发音方面都有两个重音;二是在拼法上都有后缀- teen。
除了 thirteen 和 fifteen 之外,都是纯粹地在另一个基数词的后面加上后缀- teen。
但要注意eighteen的拼法, eight 本身有 t 字母,因此只加- een。
3、第三类:twenty 二十thirty 三十forty 四十fifty 五十sixty 六十seventy 七十eighty 八十ninety 九十这类基数词共有八个。
