单数句变复数句六绝招

单数句变复数句是七年级英语试题中的一个题类，小学英语一般很少涉猎，进入初中，有的同学在做类似题时往往丢三落四，容易出错。只要注意下面的六要素，问题便迎刃而解：1．人称代词主格单数变成相应的人称代词主格复数，即I→we;you→you;she,he,it→they。如：She is a girl.→They are girls.

2．am, is 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 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.

※记住单数句变复数句的口诀。

单数句子变复数，变化规则要记住。

名词代词要变化，am, is 要变are。

this, that 该咋办，these, those 替代它。

he, she, it 要变啥，全部变they 就行了。

I要变we 别落下，名词后面把s/es加。

名前冠词去掉它，其余成分原样加。

但是，在英语中有些单数句不能变为复数句，如：Lily is fourteen.(莉莉十四岁。)His name is Jim.(他的名字叫吉姆。)等。
