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。 如: He is a man doctor.→They are men doctors. This is an apple tree.→They are apple trees. 单复数相互转换,每空一词(含缩写)。 1. The woman is a nurse.(改为复数句) The _________ _________ _________. 2. There are some old cars.(改为单数句) There _________ _________ old _________. 3. He has a new book.(改为复数句) _________ _________ new _________. 4.
