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.

数词 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，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，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（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＝eighty-four thousand two hundred and ninety-six 274，350＝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。 One—first, two—second, three—third, five—fifth, nine—ninth, twelve—twelfth 2）以_ty 结尾的单词，要先变y为i, 在加-eth.。如：thirty—thirtieth, fifty—fiftieth 3）以one, two, three 等结尾的多位数词，要将个位数变成序数词。如：twenty-one—twenty-first, one hundred and one—one hundred and first 基数词变序数词的口诀：
