本次知识点归纳：
数词是表示数量多少或顺序先后的词。分为基数词和序数词 二、重要知识点提示： 基数词
1. 表示数量多少的词是基数词，如：one, two, three等。 2. 数词的构成
1）从1－12分别由从one到twelve，12个各不相同的词表示。
2）从13－19均以后缀-teen结尾。 3）从20－90的整十数词均以后缀-ty结尾。表示“几十几”时，个位和十位之间需加连字符。 4）整百数由1—9加hundred构成。
5) 整百数和整十数之间由and连接，十位与个位之间要加连字符“-”。如果十位数为零，那就在百位和个位之间用and连接。
6）千 thousand 百万 million 十亿 billion 序数词
基变续，有规律，词尾加上th;
一二三，特殊记，词尾字母t,d,d(first,second,third);
八减t(eighth), 九去e (ninth)，f来把ve替(five---fifth,twelve---twelfth); 单词ty作结尾，ty变成tie(twenty-twentieth);
若是碰到几十几，只变个位就可以
1) 第一百、第一千、第一百万、第十亿都是在基数词后
