1.動詞變復數(shù)規(guī)則口訣：

名詞代詞要變化，am，is要變are；

This,that變成啥，these,those來替它；

He,she,it要變啥，全部變they不用怕；

人稱名詞復數(shù)變，記清不規(guī)則變化；

名前冠詞去掉它，其余成分原樣加。

2.人稱代詞主格單數(shù)變成相應的人稱代詞主格復數(shù)，即I→we;you→you;she,he,it→they

am,is變?yōu)閍re.如:I'm a student.→We are students

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

可數(shù)名詞單數(shù)要變?yōu)閺蛿?shù)形式。如:It is a cat.→They are cats

指示代詞this,that變?yōu)閠hese,those.如:This is a book.→These are books.
