<正> 冠词一般分泛指与特指两种用法:Ⅰ泛指1.普通名词中个体可数名词,如teacher,student,pen,book,desk,watch,ant,spider等表示泛指时,其冠词用法如下:A dictionary is useful.The dictionary is useful.Dictionaries are useful.上面三句意思都一样:"词典是有用的."这里指的词典是泛指概念,并没具体指哪本或哪些词典.特别注意第二句,它易与特指混淆,一般可从句子或上下文来鉴别.如下面例句中主语均是泛指:The automobile contributes to air pollution.The kerosene—powered car can greatly lessen smog.
