and只加在十位和百位之间
210 two hundred and ten 201 two hundred and one十位是0,and后直接读个位
2010 two thousand and ten 2001 two thousand and one 同理
举例：245,273,459 三位一撇 右边数起第一个“,”读thousand,第二个“,”读million,所以这个就读成 (two hundred forty five) million (two hundred seventy three)thousand (four hundred #and# fifty nine) 我在and加了#号,便于你区分,只要那加and就Ok了,这个规律会了,任何数字都会读了
