Unit 4 When is Easter? 精讲精练 PA Let’s learn 【同步精讲】 瞧瞧“数词”两家子 在英语中，数词分为两种：基数词和序数词。如one, two, three等表示数目的词被称为基数词；如first, second, third等表示顺序的词被称为序数词。 一、形式有别 序数词一般在对应的基数词后加th构成，如 fourth，sixth等，而有些序数词（如第一、第二、第三）还需要特殊记忆。为了书写简便，序数词还可以通过缩写形式来表示，其缩写形式为“对应的阿拉伯数字加上序数词的最后两个字母”，我们先看一看前五个基数词和序数词的变化和比较吧： one — first — 1st two — second —2nd three — third — 3rd four — fourth —4th five — fifth —5th 二、用法不同 1. 基数词常用在可数名词前面，表示数量。如： I can see ten birds in the tree. 我能在树上看到十只鸟。 There are forty- five students in our class. 在我们班有45名学生。 2. 序数词用来表示顺序，如楼层、每个月的第几日等。 用英语表达日期时，一般由月份加上序数词来表示，如7月1日可以写成July 1st，读作July first。 【同步精练】 一、单项选择。 ( ) 1.
