数词和量词是小学英语必须掌握的一类知识点，相信大家对数词量词并不陌生，但是不少同学还处懵懂的阶段。那么如何准确无误的拿到数词和量词的分值呢，我们今天一起来学习一下吧！
最基本的基数词
一、基数词的写法 ：
21~99的两位数，十位与个位之间用连字符。
例：21 twenty - one
32 thirty - two
99 ninety – nine
注意：数字“0”可以读作“zero”，也可以读作字母“o”。
二、百位数：
个位数基数词形式加“hundred”，表示几百，在几十几与百位间加上and。
例：101 a hundred and one.
320 three hundred and twenty
648 six hundred and forty-eight
序数词的构成
1. 一般来说，是由相应的基数词加词尾 th 构成。
例：four+ th —— fourth six + th —— sixth
seven + th —— seventh ten + th —— tenth
2. 下面这些基数词在变为序数词时，有特殊的变化。
例：one—— first two —— second
three —— third five —— fifth
eight —— eighth nine —— ninth
twelve —— twelfth
3. 十位整数序数词的构成方法是将基数词的词 y 变成 i，然后再加 eth.
例：twenty —— twentieth thirty —— thirtieth
forty —— fortieth ninety —— ninetieth
4. 两位或两位以上的基数词变为序数词时，仅将个位数变成序数词。
例：twenty –one —— twenty- first
thirty-five —— thirty-fifth
a hundred and fifty-three —— a hundred and fifty- third
基数词变序数词的口诀
基变序，有规律，词尾加上th；
一、二、三，单独记，
结尾字母 t, d, d；
八去t，九去e，ve要用f替；
整十基数变序数，
ty 将 y 变成 i ; th 前面有个 e；
要是遇到几十几，前用基来后用序。
