整数的读法
和中文四位一节不同,英文是三位一节(period),加逗号隔开:
4,321 四千三百二十一 four thousand, three hundred twenty-one
This is a four-digit number (四位数), where digit 1 is in the ones place (个位), standing for 1 one (1个一) digit 2 is in the tens place (十位), standing for 2 tens (2个十), digit 3 is in the hundreds place (百位), standing for 3 hundreds (3个百), and digit 4 is in the thousands place (千位), standing for 4 thousands (4个千).
注:十位和个位之间加连字符;美式英语不会在百位和十位中间加 and.
不像中文会在一节中的四位中间出现0时把0读出来:
101 一百零一 one hundred one
4,012 四千零十二 four thousand, twelve
不会像中文在读十/百/千位本身不为0,后面各位都为0的数字时,可以省略“十/百/千”:
250 二百五(二百五十) two hundred fifty, but not two hundred five (which is 205).
3,800 三千八(三千八百) three thousand, eight hundred, but not three thousand, eight (which is 3,008)
每个逗号之间都按三位数的读法,从右往左的第一个逗号读作 thousand (千),第二个逗号读作 million (百万,一千个千),第三个逗号读作 billion (十亿,一千个百万),第四个逗号读作 trillion (万亿,一千个十亿), etc.
