Be动词时态be made of造句是The doors of the palace were made of beat

2个回答

  • 单数(主语单数)is,复数(主语复数)are,I 后面接am,was是is和am的过去式,were是are的过去式,

    根据主语和时态的不同选择不同来选择be动词

    The doors of the palace were made of beaten gold.

    这句话的主语时doors是复数所以选择are,又因为这些门已经做出来了,是个过去的动作,所以要用are的过去式were

    i'm just joking这句话对,I 后面用am不能用is
