M10 序数词
1.用法：英语中，表示顺序时要用序数词，序数词通常与定冠词the连用。
哥伦比亚自行车队服如：the first time ―第一次‖,the fifth lesson ―第五课‖。
2.写法：序数词一般是在基数词后加--th，如：fourth ,sixth ,venth,tenth,nineteenth等，
但也有特殊情况，分类如下：
1）特殊类：这类词有三个：first ,cond ,third ，它们与基数词one ,two ,three 差别明显，应该特殊记忆。
元旦晚会唱什么歌好2）微变类：这类词从外形上看与大众类接近，也是以—th结尾，但是单词中字母有变异、省略等现象，因此在书写时易出现错误。
它们是fifth ,eighth ,ninth ,twelfth . 其中five 和twelve遵循一个规律。
将ve变为f，再加—th .
3.整“十”类。“整十”类序数词指表达“第几十”的序数词，它们的变化很有规律，
把相应的基数词末尾的y变为ie, 再加--th。
如：twenty--twentieth, venty -----ventieth.
篮球培训4.“几十几”类。序数词指的是“第几十几”，它们的变化也有规律，只把个位数的基
数词变为序数词即可。如：thirty-one变为thirty –first ,forty-five---forty –fifth .
5.第一百以上的多位序数词，由基数词的形式变为结尾部分为序数词形式来表示。如：
one hundred and twenty –first ; “第一百二十一”；
one thousand ,three hundred and twentieth “第一千三百二十”。
6序数词的缩写：有时，序数词可以用缩写来表示。主要缩写形式有：first----1st; cond ----2nd; third ---3rd;fourth ----4th; sixth ----6th; twentieth ----20th;
twenty –third 23rd ; 期中1st ,2nd, 3rd为特殊形式，其它的都是阿拉伯数字后加上th 。7注意：序数词在使用时，通常前面要加定冠词the ; 但是如果序数词前面出现不定冠词a或an时，则表示“再一，又一”。
如：We will go it over a cond time. ―我们再复习一遍‖。
