  口诀:
  单数句子变,变化规则要记住。
  名词代词要变化,am, is要变are。
  this, that变成啥,these, those来替它。
  he, she, it要变啥,全部变they不用怕。
  I要变we莫落下,名词后面把s/es加。
  名前冠词去掉它,其余成分原样加。
  具体注意下面的六要素:
  1.单数主格人称代词要变成相应的复数主格人称代词,即I→we; you→you; she, he, it→they。 如: She is a girl.→They are girls.
  2. am, is要变为are。 如: I'm a student. →We are students.
  3.不定冠词a, an要去掉。如: He is a boy. →They are boys.
  4.普通单数名词要变为复数形式。如: It is a cat. →They are cats.
  5.指示代词this, that要变为these, those。如: This is a book.→These are books.
  6. man, woman作定语修饰可数名词时,要在 "数"上与被修饰名词保持一致。但其他名词修饰名词表示 "性质"时,不作变化。
