23,813=

567,110=

6,425,000=;读法规律：

(1)百位数百位和十位之间要用and，and轻读，若十位为0则在个位前加“and”。

(2)千位数非正式文体中，十位数和个位数均为0，百位数不为0的MN00，既可以读作MthousandNhundred也可以读成MNhundred。

(3)1,0000以上大数字在用阿拉伯数字记录较大数目时，通常用逗号或空格将大数目分隔，从个位开始，三个一组。第一个“,”前为thousand，第二个“,”前为million。;1WeliveinRoom806,Building15,CityGarden.

(1)一般的序数词的构成是在基数词词尾加上th，而first、second、third是特殊的，此外八去t，九去e。

(2)以ve结尾的基数词，ve要变为f，再加th，如：five—fifth；twelve—twelfth。

(3)以ty结尾的基数词，y要变为ie，再加th。如：twenty—twentieth；thirty—thirtieth。

(4)十位或百位的基数词，只将其个位上的基数词变为序数词。如：fifty-five—fifty-fifth；twohundredandsixty-one—twohundredandsixty-first。

(5)序数词也可以用缩写形式。如：fourth-4th；twenty-third—23rd。;Socanyourememberthemeasily?;Thenhowdowereadtheseordinalnumbers?
