2.[考点解析]可数名词和不可数名词。
注意:当不可数名词用在"数词+单位词+of"结构时,如果数词和单位词是复数形式,后面的不可数名词也不能加-s或-es。如:two bottles of water?many glasses of milk?etc.
注意:凡是能用数词直接修饰的词就是可数名词,不能用数词直接修饰的就是不可数名词。
也还可以根据要判定的名词是否能任意分成两半,如果每半都能有原来整个东西的性质或特点,那么这个名词就是不可数名词。如water,把一杯水分成两份,我们还能称之为水,那water就是不可数名词。如果分割后的名词事物不能起到原来整个事物的作用,或改变了其特点时,那这个名词就是可数名词,如bike分成两份后,其中一半就不具备自行车的作用或特点,那bike就是可数名词。注意此法并不适用于所有的名词,如fish既是可数名词,意思是"鱼",变复数时,可以加-es,也可以用原形,同时也是不可数名词,意思是"鱼肉"。
