名词单复数总结推荐文档

小学英语不规则名词单复数

般情况下，直接力口s,如：apple-apples, pig-pigs, book-books 等。

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 宾格 me us you you 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

These are （some ）books .

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 ？

he/she/it they him/her/it them

例 1 This is a book . 例 2 Is that a pen ？

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 th？is What are these？

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