 名词究竟要用单数还是复数, 与名词之前的限定词有很大关系, 限定词通常分如下几类:


  1.之后肯定接单数:
  a /an, every, one, another, each, either, this, that, such a, many a, etc.
  例句: Each of them has two books.
  You can read either book. (两本书你可以随便读一本)
  2.之后肯定接复数:
  these, those, many, such, other,
  大于one的数词(ten, hundred, thousand, million…),
  a few /few /fewer /fewest, a (great /good / large /small) number of, several
  one of, all (of), some /any (of), most (of), a lot of, lots of, the rest of, plenty of
  3.之后既可接单数又可接复数: the, no, his, her, their, my, etc
  注意:这几类词大多不能同时使用
  考点一 否定限定词no
  (1)  no既可用于可数名词复数前又可用于单数前, 表示否定意义. 例如:
  No flowers in the garden. 花园里没有花.
  No one is here.
  (2)  no与否定副词not的区别是改错题的常见考点。 二者的区别在于:
  no直接修饰名词, 不能与其他限定词同时出现;
  not一般出现在be动词或助动词之后, a, an, any等限定词之前, 它是否定式的组成要素, 而不是名词的限定词
  例题:
  The mechanism 1 by which brain cells 2 store memories is ---- clearly understood.
  (A) none
  (B) no
  (C) not
  (D) nor
  答案: C
  解释: 此句主谓完整, 据选项可知空白处需填入合适的词使原句变为否定, 只有否定副词not可以和is配合构成否定句, A、B、D 之后都需要名词词组, 不符题意
  考点二 their等物主代词
  1.物主代词是常见的名词限定词, 其后既可接可数名词的单复数(his pen, his pens)又可接不可数名词(his time), 但不可与其他的限定词同时出现(部分数词除外), 例如:不能说no my car, my no car,但是可以说 My two red cars
  2.英语中许多习惯用法在表示特指时都用物主代词而不用the, 为的是更突出所属关系,这在TOEFL中是一个常考的点
  例如:Manufacutrers of consumer 3 goods often change the styles of their products.
  这里用their 而不用 the
  考点三 只接复数名词的限定词
  a (large /small /great /considerable /remarkable) number of, a variety of, a set of, a few, 等表示数的固定词组之后总是接复数名词

n.机械装置;机构,结构
  • The bones and muscles are parts of the mechanism of the body.骨骼和肌肉是人体的组成部件。
  • The mechanism of the machine is very complicated.这台机器的结构是非常复杂的。
n.细胞( cell的名词复数 );小牢房;(修道士或修女住的)小房间;电池
  • Once in the bloodstream, the bacteria adhere to the surface of the red cells. 细菌一进入血液里,就附着在红细胞表面上。
  • an amorphous mass of cells with no identity at all 不知何物的杂乱一团的细胞
n.消费者;用户;客户
