Unit6语法篇 可数名词与不可数名词   1. 从名词所表示的事物的性质来看，名词可分为可数名词和不可数名词两类。可数名词有复数形式，不可数名词一般没有复数形式。 2. 可数名词是可以计数的，它们可分为单数和复数两种形式。指单个人或事物时，用单数形式，如：a pencil一支铅笔；指两个或多个人或事物时，用复数形式，如：two pencils 两支铅笔。 3. 名词复数的变化规则：   (1) 一般在词尾加-s。   book→ books      bag→ bags   (2) 以s, x, ch, sh结尾的名词，一般在词尾加-es。   class→ classes     watch→ watches   (3) 以“元音字母+y”结尾的名词，在词尾加-s。   boy→ boys   (4) 以“辅音字母+y”结尾的名词，先变y为i，再加-es。   strawberry→ strawberries    family→ families (5)以f或fe结尾的名词，将f或fe变为v，再加-es。   knife→ knives         wife→ wives (6)一些以字母o结尾的名词变复数时有的加-es，有的加-s。   Negro→ Negroes             hero→ heroes   tomato→ tomatoes          potato→ potatoes 4. 不可数名词没有复数形式，不能直接用数词来表示数量，如果要表示数量，必须借助于其他词来完成。若用“计量单位词+of短语”表示，其数量也应通过of前面的名词体现出来。   a glass of water 一杯水   two glasses of water 两杯水 单项选择 1. ---Where are you going , Sam? ---There isn't any in the fridge .
