大额数字的英文念法250000念成Two hundred and fifty thousand大额数字每三位一读,从小到大为:thousand, million, billion. 拿到一个数字,首先从个位开始数出位数,四位为thousand,七位为million,十位为billion。

心里有数了之后,读的时候要从大位开始。

比如:2,567,000首先知道这个数是7位,读的时候以2 million开始,后面每三位就按照平时读法,之后再加上thousand,就好了。

所以读成:two million five hundred and sixty-seven thousand.1,000 a/one thousand1,000,000 a/one million1,000,000,000 a/one billion (美a thousand million)我们中文是4位4位分(万、亿)英语是3位3位分(千、百万、十亿)习惯了就好了数学英文表达3 to the
