小博士:细心的同学们肯定发现了有些名词有单数(singular)和复数(plural)两种形式,而有些名词只有单数形式,这是怎么回事呢?让我来告诉你吧。英语中,名词按其所表示的事物的性质,可分为可数名词(countable noun)和不可数名词(uncountable noun),可数名词有复数形式,不可数名词一般没有复数形式。名词单数变复数的变化规则见下表。
比一比,看谁写的单词多!
1 直接加-s的单词有:________________________________.
2 加-es的单词有:___________________________________.
3 变y为i再加-es的单词有:__________________________.
4 不规则变化的单词有:_______________________________.
