Ordinal numbers
We use ordinal numbers to order things and events. We use them to talk about dates, floors, positions, etc.
Eg: Women's Day is on the eighth of March.
    Our flat is on the seventh floor.
    He is always the first to come to school in our class.
序数词
1 = one   → 1st = first
2 = two   → 2nd = second
3 = three → 3rd = third
4 = four  → 4th = fourth
5 = five  → 5th = fifth
6 = six   → 6th = sixth
7 = seven → 7th = seventh
8 = eight → 8th = eighth
9 = nine  → 9th = ninth
10 = ten  → 10th = tenth
11 = eleven    → 11th = eleventh
12 = twelve    → 12th = twelfth
13 = thirteen  → 13th = thirteenth
14 = fourteen  → 14th = fourteenth
15 = fifteen   → 15th = fifteenth
16 = sixteen   → 16th = sixteenth
17 = seventeen → 17th = seventeenth
18 = eighteen  → 18th = eighteenth
19 = nineteen  → 19th = nineteenth
20 = twenty    → 20th = twentieth
21 = twenty-one→ 21st = twenty-first
22 = twenty-two→ 22nd = twenty-second
基变序，有规律，词尾加上th。1 2 3，特殊记，尾字母t d d。8加h，9去e，f来把ve替。ty变成tie，后跟th莫迟疑。几十几，几百几，变化个位就可以。
第一句话：序数词尾加th
英语中的序数词一般是“th”结尾。
four -- fourth
eighteen -- eighteenth
第二句话：一二三特殊记
英语序数词中的第一、第二和第三不是“th”结尾的，他们有各自对应的单词。
one -- first  two -- second    three -- third
第三句话：八加“h”九去“e”
基数词eight和nine变序数词时也有其特别之处。
eight -- eighth     nine -- ninth
第四句话：f来把ve替
英语中基数词five和twelve变序数词时，有相同的变法，他们都是把末尾的两个字母“ve”改成“f”，然后再加“th”。
five -- fifth
twelve -- twelfth
注意：
（1）英语数词中整十（二十以上）由基数词变序数词的方法：把末尾的字母“y”变成“ieth”。
twenty -- twentieth      eighty -- eightieth
（2）英语数词中第二十以上由基数词变成序数词的方法：十位数字保持基数词，个位数字由基数词变成序数致词。
twenty-one -- twenty-first
seventy-nine -- seventy-ninth
