5) 表示由两部分构成的东西,如:glasses trousers,clothes,若表达具体数目,要借助数量词 pair;suit; a pair of glasses; two pairs of trousers等。

6) 另外还有一些名词,其复数形式有时可表示特别意思,如:goods货物,waters水域,fishes().

.不可数名词对量的表示 1)物质名词


a. 当物质名词转化为个体名词时为可数。

比较:Cake is a kind of food. 蛋糕是一种食物。 (不可数) These cakes are sweet. 这些蛋糕很好吃。 (可数) b. 当物质名词表示该物质的种类时,可数。例如: This factory produces steel. (不可数) We need various steels. (可数)

c. 当物质名词表示份数时,可数。例如:
