口诀如下：

基变序，有规律，词尾加上“th”。

一,二,三（first、second、third）特殊记；

从4开始上th；5变ve改f（fifth）,8去t（eighth）,9减e（ninth）；

几十尾巴ty变tie，后面跟上th（twentieth）；

几十几，头不变，尾巴变，中间记得加个杠（twenty-fourth）；

遇到特殊要除外（twenty-first）。

一、例句用法辨析：

序数词在句中可作主语、宾语、定语和表语。

1、The second is what I really need． 第二个是我真正需要的。（作主语）

2、He chooses the second． 他挑选了第二个。（作宾语）

3、We are to carry out the first plan． 我们将执行第一个计划。（作定语）

4、She is the second in our class．在我们班她是第二名。（作表语）

注：序数词在使用时，通常前面要加定冠词the；但是如果序数词前出现不定冠词a或an时，则表示“再......”，“又......”。

1、We'll go over it a second time． 我们再念第二遍。

2、We've tried it three times．Must we try it a fourth time? 我们已经试过三遍了，还必须再试一次（第四次）吗？

二、在英语中，使用序数词时前面要加定冠词 the，但是，在下面的情况下则不加 the：

1、当序数词前有形容词性物主代词或名词所有格修饰时，序数词前不用 the。

Mother was my first teacher in my life.妈妈是我生命中的第一个老师。

2、当表达分数时，序数词前不用 the。

One fifth of the students here are from the country. 这儿1/5的学生来自农村。

3、当表达“又一，再一”时，序数词前不用 the，但可加不定冠词。

Please give me a second chance. 请再给我一次机会。

4、当表达“年月日”时，序数词前不用the。

He was born on June 6th, 1974. 他出生在1974年6月6日。

5、当序数词在句中作状语时，序数词前不用 the。

Who got there second? 谁第二个到那儿的？

6、当表达考试（赛跑等）中获得的名次时，序数词前不用 the。

She stands first in her class. 她在班上成绩排名第一。

7、示某人的多少岁 生日时，序数词前不加the。

Mary's twelfth birthday.玛丽的十二岁生日。

基变序，有规律。词尾加上th 。 一二三，特殊记。词尾字母tdd ，八减t ，九减e 。F要把ve替 ，Ty把 y 变成i，记住th 前有个e 。

1. one—first two—secondthree—third由于是前三个词，很任性顽皮，长得奇形怪状的，所以需要我们特殊记。２. four到nineteen在后面加th就可以了。但其中five, eight, nine, twelve是不听话的孩子，淘气得很。瞧：five—fifth eight—eighthnine—ninth twelve—twelfth３. twenty以上的数，整十的将“y”变“ie”再加“th”,其它的两位或多位数只需将个位数变序数词就可以了。瞧：twenty→twentieththirty-one→thirty-first(375)three hundred and seventy-five→three hundred and seventy-fifth序数词在工作时，常常懒惰地缩写成由阿拉伯数字加序数词最后两个字母的形式。瞧：1st, 2nd, 3rd, 20th, 43th对了，序数词还有一个特别好的朋友“the”。在句子中，“the”总是站在序数词的前面。瞧：Sunday is the first day of the week in America.下面有一首小儿歌帮你记忆序数词。基变序，有规律。first, second, third太顽皮。奇形怪状特殊记。４—１９加“th”, 8, 9, 5, 12小淘气：8没t, ９没e,５和12, f替ve。整十将y变ie,再把th加上去。多位数,更有趣,个位变序没问题。Health is the guarantee of one's happiness. Without a healthy body, one cannot do what he wants to, not to mention accomplishing his goals in life.One can keep fit in three ways. First, he is to pay attention to hygiene. Stay away from viruses, which means one should wash hands, take baths frequently, eat and drink properly. Stay away from bad life habits, such as smoking and overworking, which severely damage the body organs. Secondly, one is to exercise regularly. He may go jogging, swimming, bicycling, playing basketball and so on. Exercises will improve one's ability to resist diseases. And last but not least, he should be optimistic, fearing no difficulties and obstacles, and always being in high spirits.Only in good health as well as in high spirits can we greet the future, which is full of competition and challenges, and strive to achieve our ambitions energetically.
