小学英语不规则名词单复数

一般情况下,直接加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Iwe youyou he/she/it they

宾格meus you you him/her/itthem

例1She is a girl.

例2 I likeher.We likethem.

2、指示代词由单数变复数:

单数thisthat

复数thesethose

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

例2Is that apen? Are those(any)pens?

3、物主代词由单数变复数:

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

2、形容词性物主代词:myour,youryour,his/her/its their 例1 The bookis mine. The books areours.

例2 This is her pen. Thesearetheir 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 . Theseare 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 likeshis bike.They liketheir bikes.

6、连系动词由单数变复数:is/am are

例1Iam 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1This isabook . 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2She is a womanworker.

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’sthis?What are these?

例2 She likeshis bike.They liketheir bikes.

ﻫ把下列句子变成复数

1,I have a car.

2, He isan American boy.

3, It is acar.

4,Thisis an eraser.

5,That is a backpsck

6,I'man English teather

7,It's a newshirt.
