When expressing large numbers (more than one hundred) read in groups of hundreds. The order is as follows: billion, million, thousand, hundred. Notice that hundred, thousand, etc. is NOT followed by an ‘s’. Two hundred NOT two hundreds.在读较大的数字（超过一百）时，可以整百整百地读。顺序如下：十亿、百万、千、百。注意，百、千等后面不用加-s。两百（two hundred）不要读作two hundreds。
