1. 英语读数规则: 英语较大的数字读法是有规律可循的。首先，要将数字从右到左，三位三位进行分节，每一节的单位从左到右通常有trillion十亿，million百万，thousand千。其次，读数时从左往右读，每个数位中间的and可以省略，但应该在最后三位数字有数字的情况下在前面加一个and，形成A， B and C 这样的结构。最后一点，数位当中的零一般是不往出读的。2. 综上所述，这些数字分节和读法如下：96（少于四位，无法分节）ninety-six;158（少于四位，无法分节）one hundred and fifty-eight;2,347(三位分节，数位最高为thousand) two thousand, three hundred and forty-seven;86,709 (三位分节，数位最高为thousand) eighty-six thousand, seven hundred and nine;396,820(三位分节，数位最高为thousand) three hundred, ninety-six thousand, eight hundred and twenty;1,700,000(三位分节，数位最高为million) one million and seven hundred thousand.
