在本模块中我们还应注意序数词的运用。
表示顺序的数词称为序数词。序数词的
构成是这样的：
1) 序数词一般由基数词在词尾加-th构
成 。如：
ten — tenth six — sixth
2) 下面这些基数词在变为序数词时，有
其特殊的地方。如：
one — first two — second
three — third five — fifth
eight — eighth nine — ninth
twelve — twelfth
3) 以 ty 结尾的基数词，要先变 y为 i，
再加-eth。如：
thirty — thirtieth
seventy — seventieth
4) 20以上的十位或百位的基数词，只将
其个位上的基数词变为序数词就可以
了。如：
forty-three — forty-third
sixty-eight — sixty-eighth
three hundred and fifty-two
— three hundred and fifty-second
5) 序数词有时用缩写形式。如：
first — 1st
second — 2nd
third — 3rd
fifth — 5th
ninety-second — 92nd
