I am always confused with tenses which is correct?

It is good that you informed Dina about the incident. or

It is good that you have informed Dina about the incident.

What is the difference in both?

[puntoclave7]

you are a good teacher but you needs to improve his handwriting. Thank you for all you interest.

Your classes are really nice.

[BlackOutStart]

your classes are really really nice =D

Would you agree, it would've been perhaps easier if the English language had

a different plural for "you" (than "you", of course)

that to have so many "was", "were" "had", "have"?

Hi.

As an example.

A friend of mine was doctor between the age of 30-50 and now he is 55.

If I wouldnt know when he was doctor how would I ask him?

Like:

"When were you doctor?" or "When have you been doctor?"

I think the first ones right but the present perfect question sounds better to me.

[learnamericanenglish]

@TheIndustryKiller - You could say, "How long have you been a doctor?" (present perfect tense) or "When did you become a doctor?"

Those are probably the best choices.

[Carolyn4180]

@TheIndustryKiller I would hesitate saying, "How long have you been a doctor" because even though his life isn't over, his career is. This is a finished time; therefore, may I suggest something along the lines of, "How long were you a doctor?" or "When did you work as a doctor?" or "When did you retire/stop working as a doctor?"

The major difference between the simple past and the present perfect is finished v. unfinished time. The action is sometimes irrelevant.

Hi. So the auxiliary verb "do" is always used to make questions when the main verb is not the verb "to be"?

Why I can't write "Where you live?" instead of "Where do you live?"?

[learnamericanenglish]

In spoken English, some people ask the question that way: "Where you live?" But that's not grammatically correct. You need the verb "do" to make the question.

That said, if you don't use "do" when speaking, most people won't notice. I do it myself sometimes when I'm not in the classroom and I'm not paying attention to what I say.

3:20 - When would one use does as oppose to 'do'? Are they both used in the present tense?

[learnamericanenglish]

In the form of a question, use "does" with "he," "she," or "it."

Does he live in the United States?

Answer:

Yes, he does. or No, he doesn't.

Both "do" and "does" are used in the present tense as helping verbs.
