注意: ① 基数词主要表示数量。十位和个位之间需用连字符号“-”;百位数和十位数之间要用and。 如:31→thirty-one, 465→four hundred and sixty-five ② 序数词主要表示顺序,前面常用定冠词the。注意第一、二、三、五、八、九、十二、二十、三十、四十、五十……九十等的拼写。 ③ 第21-29、31-39……91-99的序数词形式,只变个位数,二十位数则用基数词;若是多位的基数词变为序数词,只需将末位数字变为序数词,前面的数词不变;当基数词用阿拉伯数字表示时,必须在该数字之后加上序数词最后两个字母。如:31→thirty-first (31st)。 ④ 百、千、百万等序数词的表示方法:hundred→hundredth, thousand→thousandth, million→millionth ⑤ 千以上的数字的读法:从后面往前每三位数字作为一个单位,用逗号分开。第一个逗号读作thousand,第二个逗号读作million, 第三个逗号读作billion。逗号与逗号的数按照三位数的读法去读。
