英文数字的读法

各种数字的英文读法 各种数字的英文读法 （1）年号的读法： 1979←→nineteen seventy-nine or nineteen hundred（and） seventy-nine； （2）电话号码、货币的读法： 　　1023←→one o two three； 　　1227←→one double two（or two two）seven； 　　4.25←→four dollars（and）twenty-five（cents）； （3）小数点的读法： 　　13.91←→thirteen decimal（point）nine one； 　　0.23= nought decmial two three； （4）算术式的读法： 　　2+3=5 Two plus three is（equals，isequal to）five. 　　5-3=2 Five minus three is equal to two. 　　3×2=6 Three times two is six. or Three by two are six. 9÷3=3 Nine divided by three makes three. 1. 整数和小数的读法 3.24可以读作three point twenty-four或three twenty-four。在美国买东西都要含税, 所以价钱多半都带有小数点, 通常小数点可以说 point， 也可以直接省略。 另外比较正式的说法为 three dollars and twenty-four cents, 但是在一般日常生活中几乎是听不到这种读法，而是直接读为 three twenty-four。在美国开支票的机会很多, 要注意的是，支票上小数的写和读与平时有所不同。在支票上，金额不仅要用阿拉伯数字写出，而且还要用英语在金额栏的最左边写出。其中整数部分的第一个字母要大写, 小数部分则用 xx/100 来表示, 并在最后加上 only。例如 12.87 写为Twelve dollar and 87/100 only。 1,245 可读为 twelve forty-five，one thousand two hundred and forty-five 或 twelve hundred and forty-five。一般来说, 四位数的读法是两个数字一起读, 如12-45。但有时为了让对方听得更清楚(特别是跟钱有关的时候)，会把 thousand 和 hundred 读出来, 像上面的第二种读法。 另外, 像第三种读法，美国人也很喜欢把 one thousand two hundred 直接说成 twelve hundred，例如1,200 可以读为twelve hundred，当然也可以说 one thousand and two hundred，这就是我们从教科书上学的读法了。 　　五位数的读法是前两个数一组, 后两个一组，中间的自己一组。例如 35,891 经常读为thirty-five thousand eight hundred and ninety-one。而六位数如100,000 则读为one hundred thousand。由于在英语中没有十万这个字, 所以十万要用 one hundred thousand, 一亿要用 one hundred million。这两个要多练习, 不然很难熟练运用。 　　整数中比较特殊的就是电话号码了，读电话号码的原则是在清楚的基础上，越简单越好。人们在读电话号码时，习惯一个数字一个数字地说, 以求清楚, 但有时为了方便起见, 也会以十位数为单位, 两个两个一起说。例如770-2145 可以读为seven seven zero, two one four five，也可以读为 seven seven o, twenty-one forty-five。总之，不管如何读，一定要清楚，不要引起歧义。 2. 分数和科学记数的读法 1/2 可以读为one half 或 one over two。1/2 的说法跟 1/3、1/4 都不一样, 它不读为 one second，而要用 one half。而 one of two 常用在数学上, 强调 1 除以 2, 这种说法在日常生活中用得比较少。至于1/3 是one third，1/4 是 one fourth等，大家对这种说法都已经很熟悉了，在此不多说，但要注意两点：在日常生活中，用 one quarter 表示1/4比用 one fourth 更多一些；2/3 要说 two thirds, 也就是说分母那个 third 要加 s，不要忘记。 　　科学记数如1.23×10-4 可读为 one point two three times ten to the minus four(negative four)；one point two three times ten minus four 或 one point two three ten minus four。第一个是最正确的说法, 但有时为了简便会有不同程度的省略。像第二、三个省略适用在别人知道你在说科学符号的场合，例如老师上课时，或同学讨论功课时，不然别人有可能会误会你的意思。 　　3. 时间的读法 　　时间的读法是先读时, 再读分。像4:28 读为 four twenty-eight。至于整点的情况，读法就更简单了，4:00 读为It's four o'clock. 或 It's four.。在生活中，4:05 不是读为 four five, 而是 five past four或four o five；3:50 不是说 three fifty，而是 ten to four，当然也可以说成 three fifty, 但是 ten to four 这样的说法就相当于中文的"还有10分就四点了"；5:30 常说成five and half 或 half past five，相当于中文的五点半了。 　　4. 一个重要的应用 　　在报地址的时候, 常有这种数字和英文字母混合的情况, 但是由于 B, D 和 T 读起来很容易混淆, 所以习惯上会加上一小句话来说明, 如 B as a in boy, T as in a teacher, D as in a dog。这样别人就可以很清楚地了解你在说哪个字母，这样，123D 就可以这么读： one two three D as in a dog。 1.Cardinals and Ordinals 基数和序数 (1)100以内的数词 基数 序数 Roman Arabic Numerals Numerals 罗马数字 阿拉伯数字 读法 数码 读法 I 1 one 1st the first II 2 two 2nd the second III 3 three 3rd the third IV
