@ Mahdi

Good.

Hey, you have not shown it [to] me!! -[shown traditionally needs have as an auxiliary but this is changing slowly to using have with the _"ed past particle".

Come on, I showed it [to] you yesterday.

Come on, I showed a photo yesterday.

Come on, I showed a photo of it/you/us/them [to you] yesterday.

If you have forgotten [about] it, I will be showing [it to] you tomorrow at this time.

[ x] = can be inserted or left out of the sentence.

@James

That seems OK to me you have a typo on "writings" ?. I am not a teacher and if I come across a sentence I am not sure about or need help with. Or a sentence that might be ambiguous I will be honest and let everybody know. So it can be discussed.

Hey, you have mot shown it me!!

Come on, i showed it a photo yesterday.

If you have forgotten it, i will be showing you tomarrow at this time.

I wrote a short story that was based off of a dream. Once completed, I showed it to my friend. She liked the story.

Because she has shown interest in my past writings, I plan to show her another short story that I wrote recently.

@James it happens to us all it is not always helpful when trying to set a good example to learners.

getting computers and algorithms to understand language is much more difficult than it was first envisaged. The best we have done so far is to have fast instantaneous pre recorded scripts that trick us into believing a machine is speaking to us/with us like a human.

@ Richard I was hoping to get one or more teachers to comment on the use of "have showed" and/or to give an example when it might be acceptable.

"have shown" as always been or mostly been the way it was taught, but "have showed" in a sentence is creeping in and an internet dictionary search showed "have shown" to be correct by all accept two that said "have showed" is now acceptable and beginning to be used.

Pleased your dwellings are now spick and spam and in a tidy state.

You have indeed shown us what you did lately, but you haven't used any of the words show, shown, showed, showing. You score marks for showing us = telling us in writing. I cannot deduct marks from a reliable person as you, can you give an explanation us to how you have shown us in grammatical terms even though you have not used the word "show" in any tense.
