BE 是 is Am ArE 的原形吗?

be是 am is are. was were been的原形

is是was 的过去式,be是它们的原形.在情态动词后,动词会恢复原形,也就是be.(因为情态动词的后面如果是动词,就必须用动词的原形)will/can/could/would/should/shall 等助动词后面用be 其他时候, 第一人称I后面用am 第二人称, 复数, 用are 单数用is

be动词包括“am、is、are”!be动词也是“连系动词”,简称“系动词”!

系动词be并非在什么时候都会 以am is are的形式出现.在有诸如will, would, shall,should can, could, may等助词后面要用原型.

be是动词 原型 它的一般现在式 是 am,is, are 它的过去式 是 was were 它的将来式 是 will be 竭诚为你服务 希望能帮到你

be 是am is are 的原形,主要用在不定式to,情态动词等的后面,例如,That cannot be my headmaster,because he has gong to London.What I want to be doctor in the future.am是当主语是I.is 是当主语是第三人称单数时.are 是当主语是第一及其第三人称的复数、第二人称时用.例如I am a student.She is a teacher.We are all stidents.They are workers.You are watching TV.

be在will can must shall等情态动词后面,都是用动词原形be.主语后面直接跟be的话就不用原形的be了,要用am is are 第一人称单数后面跟am第三人称单数后面跟is第一二三人称复数后面跟are

在句中前面有情态动词如:can, may, should, could, will, have to等时用动原be.祝您学习进步,更上一层楼!如果答案您满意,请记得采纳,谢谢!O(∩_∩)O
