今天我们一起来回顾一下,名词复数形式的变化规则；1. 大多数情况下,直接加s2. 以s x sh ch结尾的名词变复数，加es3. 以f fe 结尾的名词变复数，把f fe 变为ves.4. 以辅音字母加y结尾的名词变复数，把y变i再加es.例如，f amily 以辅音字母I加y结尾，所以复数形式为families,boy 也是以y结尾的，但它是以元音字母o加y结尾的，所以复数形式为boys5. 有些以字母o结尾的名词变复数加es,例tomatoes,potato es6. 还有一些不规则变化的，需要同学们分清记牢。

如sheep sheep，child ---- children二、练习题。
