11,234读作:eleven thousand two hundred(and),thirty—four
155,721读作:one hundred(and)fifly-five thousand seven hundred(and)twenty-one

由以上一组数字可以看出,多位数由右向左每3位有一逗号,这个逗号的作用非同小可,在记忆数字时,它可以帮我们很大的忙!
逗号的意义:
逆向第一个逗号读thousand;
向左再推三位,第二个逗号读million;
第三个逗号读billion;
第四个逗号就是trillion。
如何听写数字:
当我们听到若干thousand时,立即写下这个数,并在其后打一个逗号,并留出3位;
当听到若干million,则写下数字,并在其后打一逗号,留出6位;
听到若干billion,方法同上,在后面留出9位,后面的million、thousand依此法类推,让所有数字各就其位。
