3 小结 普通名词分为可数名词和不可数名词。 ★可数名词：表示人、事物、地点等的名称，可数名词有单数和复数两种形式之分。 名词的单数形式
一般可用a来修饰 * a car * a book 在元音发音开头的单词前用 an * an elephant * an apple

4 一般名词变复数形式的规律 1. 一般在名词的词尾加-s. 如：banana --- bananas 2. 以-o, -s, -sh, -ch, -x 结尾的名词, 在词尾加-es构成复数形式． 如：tomato --- tomatoes, watch --- watches，box --- boxes 3. 有些以-o 结尾的名词，则加-s. 如：photo --- photos 4. 以辅音字母加-y 结尾的名词，则把-y改为i，加-es. 如：family --- families

5 5. 以-f 或-fe 结尾的名词，则把-f, -fe改为v，再加-es.
如　chief --chieves（小偷）,　wife--wives（妻子）,　　 　　　knife --- knives（小刀）, leaf--leaves（叶子）, 　　　wolf--wolves（狼）, 　 life --- lives（生命） 6. 有些名词以不规则来构成复数形式． 如：man --- men（男人） , woman --- women （女人） 　　　　　　　　　　 child—children（孩子） 7. 有些名词单复数相同． 如：sheep --- sheep （羊） deer—deer（鹿）
