大数字的英语读法规则
8,742
2,463,128
1,370,000,000
2,000,030,000
thousand
billion
million
在一个多位数的最后两位(十位和个位)需要用and;只有不定冠词“a”在开头的时候, 才可以和hundred、thousand等单词连用;经常使用的hundred, thousand和million等词可以和a或者one连用，但不能单独使用。有千位和百位的数字，要使用and来连接。
英语中多位数的具体读法规则如下：
1) 在一个多位数的最后两位(十位和个位)需要用“and”，主要用在英式英语中。
e.g. 数字3012 读作:three thousand ten and two.
2) 当我们遇到1000这个整数的时候，我们要用a thousand来表达。但是要是有百位数的时候，我们就要使用and来连接。
e.g. 数字1030 读作:a thousand (and) thirty;
数字1315 读作:one thousand, three hundred (and) fifteen。
