（二）单数句变复数句的方法及规则

1．人称代词单数变成相应的人称代词复数，即

a主格:I→we;you→you;she/he/it→they。

bme →us you→you her/him/ its→them。 如：She is a girl.→ They are girls.

2.物主代词由单数变成相对应的复数，即

a，：my→our ; your→your; his/her/its→their.

b 名词性物主代词：mine→ours;yours→yours; his/hers/its→theirs.

3． be动词：am is变为are。如：I'm a student. →We are students.

4．a an 表示“一个”，只能用在单数句中，当变成复数句时，一定要把aan去掉

或改为 some/any。如：He is a boy. → They are (some) boys.

5．普通单数名词要变为复数形式。如：It is a cat. →They are cats.

6． 由单变复。即this变为these；that 变成those。如：This is a book.→ These are books.

7．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.

8. 一般情况下，形容词性物主代词在单数句变成复数句时不变。如：This is my pen.→These are my pens.

9. 当句中形容词性物主代词与句中的主语一致时，该物主代词应随主语人称的变化而变化，仍要保 持一致。如：He likes his bike.→They like their bikes.

10. 单数句变成复数句时，句式不能变。即单数句是疑问句时，变成复数句时仍然是疑问句。

如：What's this？→What are these？ ※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。

把单数句子改为复数句子的规则

一、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.

二、 am, is 变为 are。如：I'm a student. → We are students.

三、不定冠词 a, an 要去掉固定搭配除外。如：He is a boy. → They are boys.

四、可数名词单数要变为复数形式。如：It is a cat. → They are cats.

五、指示代词 this, that 变为 these, those。如：This is a book.→ These are books.

六、man或woman修饰可数名词时，在整个句子变成复数的情况下，它们也变为复数形式men, women。 例如： She is a woman teacher.→ They are women teachers.

注意：普通单数可数名词要变为复数形式，但当名词修饰名词表示“性质”时不作变化。

例如：apple tree → apple trees boy student → boy students That’s an apple tree. → They are apple trees.

七、单数句变复数句时，句中的形容词、定冠词、副词、疑问词、介词短语和感叹词等保持不变。 例如： Who is she? 她是谁？→ Who are they? 她们是谁？

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。
