How many tenses are there in English?
12:
	3 time frames (past, present, future)
	4 aspects for each one (simple, progressive, perfect, perfect progressive)
In every time frame:
progressive = [be] + verb(ing)
perfect = [have] + past participle
perfect progressive = [have] + been + verb(ing)

“She may be sick today.”
- This is simple present, because if I’m sure about it, I would say, “She is sick today.”
“Coal and oil may have become depleted by the end of the next century.”
- This is future perfect, because if I’m sure about it, I would say, “Coal and oil will have become depleted by the end of the next century.”
(“She may have been sick yesterday” is simple past, because if I’m sure I say “She was sick.”)
