1.可数名词单复数及发音【参考Lesson 17语法部分】；
2.英语的数词及写法(Part 1)
1)英语中的数词（表示数量多少或先后顺序的词）分为基数词（表示数量的，如：one; two; three; four等）和序数词（表示顺序的，如：first; second; third; fourth等）。这一讲先从基数词开始。
2)基数词从0到10的英文写法如下：
zero,one, two, three, four, five six，seven，eight，nine，ten
3)基数词从11到19的英文写法如下：
eleven，twelve，thirteen，fourteen，
fifteen，sixteen，seventeen，
eighteen，nineteen
这里除 eleven, twelve, thirteen, fifteen, eighteen为特殊形式，fourteen, sixteen, seventeen, nineteen都是由其个位数形式后添加后缀-teen构成。另外，从13(thirteen)开始，一直到19 (nineteen)，单词都是以后缀-teen收尾(这下你该明白teenager这个词指的都是什么年龄段的人了吧)。
4)从20到99的写法：
整数几十中除twenty，thirty, forty，fifty，eighty为特殊形式外，sixty，seventy，ninety都是其个位数形式后添加后缀-ty构成。
在表示几十几时，注意在几十和个位基数词形式之间添加连字符“-”，如：35 thirty-five 99 ninety-nine
5)百位数的写法：
用个数基数词 hundred, 如：100就是one hundred; 400-four hundred(注意:不论是几百，hundred结尾不加s); 800-eight hundred
如要表示带有零头的百位数，需要在百位数和后面的数之间加上and，如：
101 - one hundred and one
320 –three hundred and twenty
678 –six hundred and seventy-eight
