　　把單數(shù)的句子成復(fù)數(shù)的句子很簡(jiǎn)單：變法是把能變成復(fù)數(shù)的詞變成復(fù)數(shù)，但a或an要把去掉。特殊疑問(wèn)詞、形容詞、國(guó)家及地點(diǎn)通常不變。

　　把下列句子變成復(fù)數(shù)

　　1、I have a car we have cars

　　2、He is an American boy. They are American boys

　　3、It is a car They are cars

　　4、This is an eraser These are erasers

　　5、That is a backpsck Those are backpacks

　　6、I'm an English teather We are English teathers

　　7、It's a new shirt They are new shirts

　　8、He's a boy They are boys

　　9、She's a singer They are singers

　　10、What's this in English? What are these in English?

　　第二：就劃線部分提問(wèn)

　　就劃線部分提問(wèn)的變法：

　　1、先根據(jù)劃線部分找到特殊疑問(wèn)詞。

　　2、 再把沒(méi)劃線的部分變成一般疑問(wèn)句的語(yǔ)序。

　　3、 特殊疑問(wèn)詞通常有：what/ where/ who /whosc/ how/how old/ what colour/ what class /

　　what grade/what row/what school
