  • 1) 当人称做主语,谓语动词是be动词时,有顺口溜:be动词三变化;am,is are .我I用am ,你 you 用are .is 紧跟 他她它he she it.复数人称都用are.

    2) 当人称做主语,谓语动词是实意动词动词时..根据时态要求用过去时-ed.此时没有人称变化.weshehethey walked to school.

    3)当人称做主语,谓语动词是实意动词动词时..根据时态要求用进行时(be +Ving).此时有人称变化.可用以上顺口溜:I am going to school .She is going to school .We are going to school ...

    4)当物做主语时.物是单数或Ving形式,谓语是be 时.用单数.THe book is new.Going to bed early is good for us.

    5)当物做主语时.物是复数,谓语是be 时.用复数.THose books are new,there be 结构遵讯就近原

    6)当物做主语时.物是复数或单数,谓语是实意动词时.Ved 都没有变化
