Could You Please Help Me To Study English By Myself?

you could put a ? question mark at the end of this sentence.

You could also put, "has been for me". It sounds more appropriate here even though "has been to" is technically okay.

Well,I recently read about "therapy dog" helping others.

You could make "therapy dogs" plural here with an 's'.

So I train her to become one.

Train ---> trained (keep the verb tense consistent)

She learn quickly, and we visited the nursing care facility in (the) neighborhood.

Learn ---> learned (keep verb tense consistent)

other options as well but if you want it all in past tense, then make this change.

You should have seen the effect that she * had on * the elderly patients there.

Everyone was genuinely delighted*,* and wanted to interact with her.

You could erase the comma to make it flow more. What it's saying is: the elderly were pleased and wanted to play with the therapy dog. I hope that clarifies any uncertainties.

"Play with her" is more appropriate here. Interact sounds distant. In English, we usually say people 'play with animals' rather than people 'interact with animals.'

And Mandy loved all the attention as well.

I think we are going to go there again in a few weeks from now.

Well, I'll write to you again soon. I hope everything is fine with you. Please take care.
Love,
Maria(and Mandy, too)

>Could you please make the other sentence as same meaning?
>Could you please make the other some sentence by using "have been to / has been to"?

In this case, "has been to" is okay. "Has/have" here are referring to the subject, 'she' (Mandy), not to her qualities (faithful and devoted). The way you have it works. See above comments though.

>Could you please make the other sentence as same meaning?

I'm not clear what you mean. Could you rephrase it? The way you have it works here.

>Could you please make the other some sentence by using "have on / had on"?

The way you have it is correct. She had an effect on the elderly patients. If Mandy had a friend and there were two therapy dogs, they would have double the effect. They would be so sweet and sincere, the effect they would have on the elderly would be lovely.

>I don't know why is *,* needed. Could you please teach me about that?

I'm not sure what you mean, but see if the above comments are any help.

That would be really helpful if you could consider to my questions.
Thanks in advance.

hope this helps!

please feel free to reach out for any other help you may need or for clairity around any other subjects relating to written or spoken English!

best,

Michael
