初中英语数词

初中英语数词讲解数词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。一、基数词 1.基数词就注意以下几点：（1）几十几的基数词的十位数与个位数之间要用连字符“-”连接。如： eighty-five 85 twenty-six 26 （2）三位数的基数词须在百位和十位（若无十位则和个位）之间用and连接。如：three hundred and sixty-five 365 two hundred and six 206 （3）基数词的复数形式。当基数词hundred，thousand，million，billion等词前有详尽数词或several修饰时，必须用单数。如： several hundred year“s ago几百年前 two thousand students两千个学生 2.基数词的分外用法：（1）表示“几十年代”或“几十岁”时，用逢十的基数词的复数形式。如：in the 1990“s 20世纪90年代 i n one“s twenties在某人20多岁时（2）用在习语中。如： in twos and threes三三两两地

二、序数词序数词应注意的几点事项： 1.多位数的基数词变成序数词时，只需将末位基数词变成序数词，前边的基数词不变。如： forty-two 42 forty-second第42 nine-hundred 900 nine-hundredth第900 2.当序数词用阿拉伯数字表示时，必须在数字后加上序数词的最后两个字母。如：21st第21 32nd第32 3.序数词前大凡要用定冠词the，如果序数词前用a或an时，则表示“又一；再一”（没有详尽范围的限制）。如： Though he had failed twice，he wanted to try a third time. 尽管他已失败了两次，他还想再试一次。 The little monkey had had three apples，and he wanted to eat a fourth one.那只小猴子已经吃了3个苹果，他还想再吃一个。三、分数和百分数 1.分数（1）分数的分子用基数词，分母用序数词。如： one fifth五分之一 one tenth十分之一（2）当分子大于1时，分母用序数词的复数。如：
