一、基数词的表达和用法1. 基数词的表达(1)表示数目多少的数词叫基数词，基数词后面通常接可数名词。
　　(2)13—19的基数词以teen结尾，20—90的整十位均以ty结尾。十位数与个位数之间要加连字符“-”，如：thirty-ne 31；百位和十位之间加and，如：ne hundred and fifty 150。2. 基数词的用法(1) “基数词＋单数名词＋形容词”构成合成形容词，如：a five-year-ld by一个五岁的男孩，an 800-metre-lng bridge 一座800米长的桥a tw-hur ride=tw hurs’ ride 两小时的车程
(2)当hundred，thusand，millin这些词前面有具体的基数词(如 ne，tw，three...或 several，a few 等)时，需用单数形式，直接修饰名词，不与 f 连用，强调 “确切的数目”，如：tw thusand peple两千人，three hundred metres三百米。当表示 “成百上千、成千上万、数百万” 等不确切的 “大量、许多” 时，需用复数形式(hundreds，thusands，millins)，且必须与 f 连用，修饰可数名词复数，如：hundreds f peple数百人，thusands f birds 成千上万的鸟。
二、序数词的表达和用法1. 序数词的构成和表达(1)表示顺序的数词叫序数词，序数词的构成：①序数词一般是以与之相应的基数词词尾加-th构成，如：furth，tenth。但以下这些基数词变为序数词时，有特别之处。如：ne—first，tw—secnd，three—third，five—fifth，nine—ninth，twelve—twelfth。②以ty结尾的单词，要先变y为i，再加-eth。如：thirty—thirtieth，fifty—fiftieth。③以ne，tw，three 等结尾的多位数词，只将个位数变成序数词。 如：twenty-ne—twenty-first。
(2)基数词与序数词对应的变化：
　　2. 序数词的用法(1)序数词前面一般加定冠词the或物主代词等限定词。如：the first time第一次，his secnd sn他的第二个儿子。(2)如果序数词前加不定冠词a/an，则表示“又一，再一”。如：I’ve tried twice.And I want a third try.我已经试过两次了，还想再试一次。(3)“the＋序数词＋最高级＋名词＋in/f＋比较范围”的表达。如：The Yangtze River is the first lngest river in China.长江是中国的第一长河。
三、分数、小数、百分数的表达1. 分数的表达：分子用基数词，分母用序数词，分子是1，分母用单数，分子大于1，分母用复数。当分母是2时，可用half；当分母是4时，可用 quarter。如： ne third 1/3，tw thirds 2/3，a half 1/2，ne furth 或 a quarter 1/4，three furths 或 three quarters 3/4。2. 分数作主语时，谓语动词要根据分数后的名词来确定，如果是不可数名词或是可数名词单数则谓语动词用单数，如果是可数名词复数则谓语动词用复数。如：
Three quarters f the infrmatin cmes frm the Internet.四分之三的信息来自互联网。Half f the apple has been eaten.这个苹果的一半已被吃掉了。One third f the students here are frm rural areas.这里的学生有三分之一来自农村地区。3. 小数和百分数的表达法(1)小数点读作 pint，小数点前后的数用基数词表示。如：zer pint zer fur 0.04。(2)百分数用 percent 表示。如： three percent 3%。
四、时间的表达1. 时刻的表达：小时、点钟、分钟、秒钟要用基数词。
　　2. 年份、年代的表达(1)“年份”用基数词。nineteen ninety-nine 1999年，nineteen hundred 1900年，(the year) tw thusand 2000年，nineteen zer five 1905年(2)“年”用基数词，“日”用序数词。1998年6月8日 写作：June 8，1998；读作：June the eighth，nineteen ninety-eight或the eighth f June，nineteen ninety-eight(3)世纪、年代的表达 in the nineties在90年代，in the nineteenth century在19世纪，in the 1730s或1730’s在18世纪30年代
五、编号的表达1. 用基数词来表示编号时，应放在名词之后，基数词和名词首字母大写，且不需任何冠词。如：Page One 第一页；Rm 301 301房间；Carriage N.5 第五号车厢。2. 用序数词来表示编号时，应放在名词之前，且前面需加定冠词the。如：the first page第一页；the tenth week 第十周。六、倍数的表达英语中，表示倍数时，“一倍”用 nce 表示；“两倍”用 twice 表示；三倍或三倍以上用“基数词＋times”表示。表达倍数常用以下几种结构。
1. 倍数＋形容词或副词的比较级＋than…Her bedrm is twice bigger than yurs.她的卧室比你的大两倍。2. 倍数＋as＋形容词或副词原级＋as…The ball is three times as heavy as that ne.这个球的重量是那个球的三倍。3. 倍数＋the＋n.(size/weight/height/length…)＋f…The river is fur times the length f the stream nearby.这条河的长度是附近小溪的四倍。
