Period 5 数词 Teaching Aims:
1.掌握数词的概念、分类，数词可分为：基数词和序数词两种； 2.掌握数词的基本用法.Teaching Procedures: Step 1 Basic Conception 1)．数词可分为：基数词和序数词两种；基数词表数目，序数词表顺序。基数词在句中可作定语、主语、宾语（介宾）、表语、同位语等；序数词主要作定语，其前面须加上定冠词the，此外，也作主语、宾语、表语等，这时，被它所修饰的名词往往被省略。如：The first ( person ) to arrive is Kate.2)． 分数表达法：先写基数词表示分子，后写序数词表示分母，如果分子大于1时，分母要加 “s”。如：one-fourth, two-fifths, three-tenths 3)． 小数表达法：小数点前的整数按基数词的规则表示，小数点写作point, 小数后的数字应按其数字直接表示出来。如：18.38可写成：eighteen point three eight。注意：小数在句中常作定语，尤其在比较方式状语从句中被使用。如：This stone is 3.5 times heavier than that one.4)． 年、月、时间表达法：年份用基数词，日期用序数词，时间用基数词，其顺序由小到大。
5)． 英语中没有 “万”和 “亿”，要按十进位法来推算。如：35，845，可写成thirty-five thousand eight hundred and forty-five。又如：100，000，000可写成a hundred million。
6)． Hundred, thousand, million, dozen, score这些词前面如又表示具体数字的词，它们不能加 “s”,反之则须加 “s”。如：three hundred people, thousands of people。
7)． 两组与数词有关的介词短语：
⑴ in+定冠词the+数词的复数形式，表示年代。如：in the 1870s或1870\'s ⑵ in+物主代词+数词的复数形式，表示某人的年龄。如：in one\'s thirties。有时在物主代词后面可加上形容词early或late使其含义更确切些。如：The young man is at most in his early thirties.Step 2课时练习
