一、序数词
1、表示数目的数词,叫基数词。如:one two three four……
2、表示顺序的数词叫序数词。一般为“基数词 + th”构成序数词。
3、基数词变序数词方法:
基变序,有规律,词尾加上th。123特殊记,词尾字母t,d,d。 8少t,9 去e,f 来把v e替。整十变y为ie,后跟th莫迟疑。 若想表示几十几,只变个位就可以。
把下面的基数词变成序数词。
One________ two________ three________ five________ eight________ nine________eleven________ twelve________ twenty________ thirty______ thirty-one________ thirty-two________
4、序数词的用法
序数词前面要加:the 、形容词性物主代词、名词所有格 ,而且一次只能用其中的一个。
This is the first student . 这是第一名学生。
He is my secend son . 他是我的第二个儿子。
That boy is Jim’s third son . 那个男孩是吉姆的第三个儿子。

三、英语日期表示法:

2月2日:February the second == February second == February 2 nd
3月3日:March the third == March third == March 3 rd
