求助英语have/has was/were should/would do/did/does 这几个单词怎么区别怎么使用啊?

have用于第一第二人称（i ,you),has用语第三人称he/she
was/were是is/are的过去时.放主语后面做谓语
should/would 后跟动词原形 should是应该是意思.语法should have done(done意思是动词过去分词）意思是本应该做什么,实际是却没做,WOULD ,一般用法,WOULD LIKE TO do sth,意思是更愿意做某事
did是DO的过去时,does是DO的复数形式,
do和does是一般现在时的助动词,did是一般过去时的助动词,does
用于第三人称,而do是第一人称,用于疑问句
eg,How do you know the answer?
How does she know the answer?
Where did he go yesterday?

do does did have has had 作助动词怎么造句英语助动词的用法has 跟 have did 跟 does这些怎么区别怎么用? was were have has do does用法求大神帮助怎样区分疑问句中使用am is are was were还是do does did呢? 英语中am,are,is,was,were,there is,there are,has,have,does,do 的主 do did does done doing这几个都是单词吗虚拟语气中的would/conld/should do/have done 与 did/had done有何区别（英语）用was,were,do,does,did,can各造二个一般疑问句. （英语）用was,were,do,does,did,can各造一个一般疑问句. do did does怎么用? do did does 怎么用? 几个英语用法HAVE BEEN 和 HAS BEEN 有什么不同 WERE怎么用?
