《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

students, apples, bags, trees, books, brothers.

foot→ feet, tooth→ teeth, mouse→ mice,man→ men, woman→ women
2)单复数同形:
sheep→ sheep, deer→ deer, Chinese→ Chinese,
3)加ren

3)集体名词,people ,class, police 等本身就是复数
