1、名词单复数资料引用 英语语法2-名词单复数可数名词有单数和复数两种形式。这和汉语不同。比如,在汉语中,我们说一个苹果,那就是一个苹果,没什么特殊变化。你要说三个苹果,只需把“一”换成“三”就可以了。而在英语中,一个苹果是oneapple,三个苹果是threeapples,不尽数量词变化了,名词也有相应的变化。名词变复数的规则:分为规则变化和不规则变化。第一部分:规则变化情况 构成法 读音 例词1.一般情况(包括以e结尾的名词)加-s-s在清辅音ptkf后读s在浊辅音和元音后读z在辅音szd?后读iz口诀:清清浊浊元浊Cups,cats,cakes,roofs,flags,keys,faces2
