1、新初三暑假语法讲义第五讲 数词 连词第五讲 数词 连词内容基本要求略高要求较高要求数词一、基数词与序数词的构成及用法；二、分数、时间、日期的表达法。hundreds of 名基数词+hundred + 词基数词+hundred of the 复 数倍数，约数连词一、连词的分类；二、并列连词和从属连词的用法；三、易混连词辨析。从属连词易混连词辨析清单一、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。1最基本的基数词如下表表示。1 one 11 eleven100 a hundred 2 two 12 twelve20 twenty1000 a thousand3 three 13 thi
2、rteen 30 thirty 1,000,000 1 million4 four 14 fourteen 40 forty10,000,000 ten million5 five15 fifteen 50 fifty100,000,000 a hundred million6 six 16 sixteen60 sixty1,000,000,000 a billion7 seven 17 seventeen70 seventy8 eight18 eighteen80 eighty9 nine19 nineteen90 ninety10 ten【注】：1) 基数词1-12是独立单词，需逐个记忆。
3、1319 是由个位数加后缀-teen构成。注意其中13、15、18的拼写是thirteen, fifteen, eighteen。2) 2090 由个位数加后缀-ty构成，注意20, 30, 40, 50和80的拼写分别是twenty, thirty, forty, fifty, eighty。2199中非整十的两位数是由整十位数加连字符“-”，再加个位数构成。如：81 eighty-one。3) 101999 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。4) 1000以上的基数词先写千位数，后写百位数，再加and，最后
4、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。5) 多位数的读法：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）
5、，第三个间隔或逗号前是a thousand million 或a billion(十亿)。每隔三位分段以后就都成了101999。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。【真题回放】1.
