二、单数句变复数句

把单数的句子成复数的句子很简单：变法是把能变成复数的词变成复数，但a或an要把去掉。特殊疑问词、形容词、国家及地点通常不变。

1、人称代词由单数变复数：

主格I we you you he/she/it they

宾格me us you you him/her/it them

例1 She is a girl .

例2 I like her. We like them.

2、指示代词由单数变复数：

单数this that

复数these those

例1 This is a book . These are（some）books .

例2 Is that a pen？Are those（any）pens？

3、物主代词由单数变复数：

1、名词性物主代词：mine ours，yours yours，his/hers/its theirs

2、形容词性物主代词：my our，your your，his/her/its their

例1 The book is mine. The books are ours.

例2 This is her pen. These are their pens.

4、一般情况下，形容词性物主代词在单数句变复数句时不变。

例1 This is my book . These are my books .

5、当句中形容词性物主代词与句中的主语一致时，形容词性物主代词

应随主语人称的变化而变化，仍要保持一致。

例1 He likes his bike. They like their bikes.

6、连系动词由单数变复数：is/am are

例1 I am a teacher. We are（some）eachers.

7、a/an表示一个，只能用在单数名词前，当单数句变复数句时，

一定要把a/an去掉，或改为some/any。

例1 This is a book . These are（some）books .

例2 Is that a pen？Are those（any）pens？

8、当名词作定语或在介词短语中作介词宾语充当除宾语以外的

其它成分时，该名词不变。

例1 He is a boy student .

They are（some）boy students.（man和woman）除外。

例2 She is a woman worker.

They are（some）women workers.

9、单数句变为复数句时，句式不能改变，即单数句是疑问句时，变为复数句时，仍然是疑问句。

例1 What’s this？What are these？

例2 She likes his bike. They like their bikes.
