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
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. 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)
★不可数名词 物质名词和抽象名词属于不可数名词如:water,rice,fish,meat 等。 特别记住: work chalk time space music money weather cotton homework wood information news medicine
