注:不可数名词可以与表示量的可数名词连用,借以表示"可数"的概念,我们可以加 a(n) piece [sheet(张), suit(套), tube(管), packet(包), item(条,则), bar(条), basket(篮子), glass(杯),bunch(束), pair(双,对), bowl(碗), portion(份), herd(群), series(系列), shower(阵) etc. ],如:a piece of advice(一条建议) /a basket of fruit(一篮水果) /an item of information (一则信息)/a kind of protection(一种保护)等。
2. 有些抽象名词的意思可以转变成为具体名词,这时要用其复数形式
The insurance company paid $10000 in damages for the accident. ("damage"本来为不可数名词"损害",变复数后意思是"损失赔偿费".)
单复数含义不同的名词还有:communication(通讯)communications(通讯系统,通讯工具);cloth(布)clothes(衣服);content(内容)contents(目录);convenience(便利)conveniences(便利设备);humanity(人类)humanities(人文科学);necessity(需要)necessities(必需品);pain(疼痛)pains(辛劳);ruin(毁灭)ruins(废墟,遗迹);sand(沙子)sands(沙地,沙滩);wood(木材)woods(树林);work(工作)works(工厂,著作)。
另外,有些名词通常只用复数形式,如:fundamentals(基本原则),goods(货物), means(方法), rapids(急流),shorts(短裤), sweets(欢乐), valuables (贵重物品)。
