   1. 成双成对的好基友们


  有些物体是由成双成对的两个部分组成,例如两条腿的裤子、两个镜框的眼镜等。这些单词总是以复数形式出现。例如:
  衣物类
  trousers 长裤(英式英语)
  pants 长裤(美式英语)
  shorts 短裤
  jeans 牛仔裤
  briefs 内裤
  pyjamas 1 (包括上衣和裤子的)睡衣
  物品类
  spectacles 眼镜(英式英语)
  glasses 眼镜
  binoculars 2 双筒望远镜
  goggles 3 护目镜
  scissors 剪刀
  pincers 钳子
  值得注意的是,一旦上面的单词以单数形式出现,就意味着词义发生了变化。例如:
  trouser 裤子的一条腿
  glass 玻璃
  pincer 螃蟹等动物的鳌
  2. 不加s我也是复数
  有些单词特指某个群体,表面上看它们和单数名词一样都不加s,但这些词后面的必须加are、have等用于复数的动词。例如:
  people 人
  folk 人
  police 警察
  crew 飞机、轮船上的全体工作人员
  3. 变身复数你也看不出来
  有些来源拉丁语、法语等的外来词虽然在原本的语言里是复数,但因为结尾不加s,所以对英语学习者来说很不容易分辨。这些单词后面的动词也必须是复数形式。例如:
  bacteria 细菌
  criteria 4 标准
  marginalia 写在书页空白处的批注
  4. 习惯用法
  某些词组中的单词习惯上会使用复数,例如bacon and eggs(咸肉和煎蛋)。这样的例子还有:
  good manners 有礼貌
  bad manners 没礼貌
  bits and pieces 零碎的
