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。 Eg:把下列句子变成复数 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,Im an English teather ------We are English teathers 7,Its a new shirt---- They are new shirts 8,Hes a boy ----They are boys 9,Shes a singer ------They are singers 10,Whatsthis in English?---- What are these in English?
