连系动词 am is 变成 are。

冠词a an要去掉，改为some, any也可以。

名词做定语，介宾不要变；有man和woman也例外。句式不要变。

一. 人称代词由单数变复数：

1 主格 I --- we ，you --- you ，he/she/it --- they .

2 宾格me--- us ，you--- you ，him/her/it --- them .

I like him. ----- We like them.

二．指示代词由单数变复数：

this ----these ， that--- those

This is an English book. These are（some）English books .

Is that a new pencil？ Are those（any）new pencils？

三．反身代词：第一人称myself---ourselves 第二人称yourself---yourselves 第三人称 himself/ herself / itself ----themselves

I am teaching myself English. ---We are teaching ourselves English.

The child herself draws this picture.--The children themselves draw these pictures.

四. 物主代词由单数变复数：

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

That is her pencil-case.---- Those are their pencil-cases.

一般情况下，形容词性物主代词在单数句变复数句时不变。

五．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。

He likes his bike. ----- They like their bikes.

六. 连系动词由单数变复数：is/am ---- are

一定要把a/an去掉，或改为some/any。

This is an orange. ---These are（some）oranges.

Is that an eraser ？--- Are those（any）erasers？

八．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。

He is a boy student.------They are（some）boy students.

（man和woman）除外。She is a woman worker.---They are（some）women workers.

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。

What’s this？---- What are these？
