《How much are these socks?》PPT课件15
1.基数词
基数词的写法：
(1)1～12，拼写和读音没有什么相似之处，无规律可言，应逐一进行记忆。
(2)13～19，表示“十几”，在个位数后加后缀teen，并且重音在后。注意(13)thirteen，(15)fifteen分别由three和five转化而来；(18)eighteen是eight中加een而来。
(3)twenty～ninety整十以ty结尾。
(4)几十几要用连字符。
eg：24 twentyfour
(5)三位数的词需注意百位和十位之间加and。eg：
148 one hundred and fortyeight
2.基数词的巧记方法：
英语数词不难记，
找出规律就容易。
零至十二样各异，
一个一个单独记，
后加teen变十几，
thirteen，fifteen看仔细。
eight原本就有t，eighteen只缺een。
二十至九十后加ty，twenty不同重点记，forty去掉字母u，thirty，fifty更出奇，十位数后个位数，表示数值几十几，按序排列不费力，连字符号莫丢弃，巧学巧记加努力，hundred是你好成绩。
