《可数名词变复数的变化规则》导学案
名词在英语学习中是非常重要的，它分为可数名词和不可数名词。不可数名词可以简单地理解为无法用数计算的名词，比如肉类meat、chicken等,液体water，juice，orange，milk等。可数名词分单数和复数，单数常和a, an, the冠词连用，如a dog, an apple, 但是可数名词变复数是同学们在学习时接触过的语法现象，也是比较难以掌握的，同时也是每次考试涉及到的重要知识点，本节课我们一起总结可数名词变复数的规则。
一、名词复数的规则变化
1)一般的名词在词尾加-S
students, apples, bags, trees, books, brothers.
2) 以s、x、sh、ch结尾的名词加-es
glasses, boxes, brushes, matches.
3) 以辅音字母加y结尾的名词，变y为i加es

二、名词复数的不规则变化

2)单复数同形：
sheep→ sheep, deer→ deer, Chinese→ Chinese,
