Present Perfect:
The present reflects an activity that took place in the past, and continues now. We use the Present Perfect to say that an action happened at an unspecified time before now. The exact time is not important. You “can not” use the Present Perfect with specific time expressions such as: yesterday, one year ago, last week, when I was a child, when I lived in Japan, at that moment,that day, one day, etc. We CAN use the Present Perfect with unspecific expressions such as: ever, never, once, many times, several times, before, so far, already, yet, etc

Examples:
1.-Professor White has spoken Spanish since he was nine years old.
2.-I think I have met him once before.
3.-Have you read the book yet?
4.-Nobody has ever climbed that mountain.
5.-Has there ever been awar in Mexico?

Present Progressive (Present continuous):
The present progressive expresses in compete action in progress at a specific time. It is a verb category with a two principal meaning components: (limited) during (possible) and in completion.
Use 1: Use the Present Continuous with Normal Verbs to express the idea that something is happening now, at this very moment. It can also beused to show that something is not happening now.

4.-What are you doing?
5.-Why aren't you doing your homework?

Use 2:In English, "now" can mean: this second, today, this month, this year, this century, and so on. Sometimes, we use the Present Continuous to say that we are inthe process of doing a longer action which is in progress; however, we might not be doing it at this exact second.

May,might, and could (possibility):
We use may, might, and could + base verb to say that something is possible now or in the near future, and we also use them to express that we are not completely sure about something. When making a question may and could are more common than might and a little more formal than can.

Wen the doer is unknown or unimportant and to emphasize the object of the verb.
