表示顺序的词叫作序数词。解答此类试题时，考生首先需要仔细分析语境，再根据语境中的提示，通过简单的计算或生活常识推理得出答案。序数词的基本用法如下：
序数词(2015.20)　
1. 序数词可以用来表示顺序
the fifth floor July 5th, 2015 等。
2. 序数词前若无其他修饰成分，必须加the, 其后接单数名词。如：
The second photo is what I really want.
3. 序数词前若有形容词性物主代词、名词所有格等限定词，则不加the。如：
Tomorrow will be my fifteenth birthday.
4. 序数词前面也可以加不定冠词a或an, 表示“又一， 再一”， 内含顺序性。如：
We’ve tried it three times. Must we try a fourth time?
分析山西近5年中考真题可知，词语运用中考查过1次基数词变序数词，且考查不规则变形。解答此类试题，掌握基数词与序数词的用法及变化规则是关键。
用数词的适当形式填空(2017.78)　　
1. 如何判断所填词用序数词
(1) 若表示“第几”用序数词；
eg:I have visited this city twice, so this is my third time here.
(2) 若空格前有the修饰，空格处常用序数词(2017.78)；若空格前有a修饰，空格处常用序数词，表示“又一，再一”；
eg: The tenth day of September is Teachers' Day.
(3) 若空格前有形容词性物主代词或名词所有格修饰，空格处用序数词。
eg:Today is my grandmother's seventieth birthday.
Even though we have failed twice,we'll have a third try.
2. 常见的基数词和序数词转换
one—first two—second three—third
four—fourth five—fifth six—sixth
seven—seventh eight—eighth nine—ninth
ten—tenth eleven—eleventh twelve—twelfth
thirteen—thirteenth fourteen—fourteenth fifteen—fifteenth?
sixteen—sixteenth seventeen—seventeenth ?eighteen—eighteenth
nineteen—nineteenth twenty—twentieth thirty—thirtieth
forty—fortieth fifty—fiftieth sixty—sixtieth
seventy—seventieth eighty—eightieth ninety—ninetieth
基变序，有规律，末尾加上?th；
一二三，特殊记first, second, third;
八去t，九去e, f来把ve替；
若要表示整十数，变y为ie再加th;
若想表示几十几，只变个位就可以。
