completed the project??

現在完成式:I have not yet completed the project.
我未做完報告
其他都係文法錯嘅.
你可以咁寫:
I do not complete the project.我e+/經常冇做完
complete呢個字少用進行式(is/am/are/was/were/have been/has been + xxing),你可以用
I am still working on the project.我重做緊=未完成,如果成篇用過去式,都可以用:
I was still working on the project.
I did not complete the project.我之前冇做過,用喺以前/故事.
如果全部都用過去式,再表達喺更早時間完成咗,用
過去完成式:I had not yet completed the project.
被動式先用is/was/were/are ,但用I開頭就用唔到呢個,你可以改做:
The project is/was not completed

I have not yet completed the project.(我還未完成作業)
I was not completed the project.(作業未完成我)
I am not completed the project.(作業不 會完成我)
If I were not completed the project,...(假如作業未完成我)
I do not completed the project..(我不 會 完成作業)
I did not completed the project..(我未完成作業)

For these six sentences , only the first one is correct .

I do not yet completed the project <-
I did not yet completed the project<-

For these two sentence , there is a fatal grammar mistake

Noun after do / did / does / --> No s No ed

Correct one: I don't / didn't complete the project
Although it correct in grammar but it is doesn't make sense.

I was not yet completed the project.
I am not yet completed the project.
I were not yet completed the project.
For these 3 sentences , totally wrong in grammar and doesn't make sense.

I haven't finished the project yet <--
you are telling people about the project now with the result of the past ( you have finished the project <--result)
