Tenses

Like what I have said that I always suggest somebody else to know the five thing that I have mentioned above. And one of them is tenses.
Every sentence in English has tense means time and there are three tenses in English actually. Those are present, past, and future and each one has four branches those are simple, continuous, perfect, and perfect continuous. So, the tenses are twelve if we count them with the branches. They are simple present, present continuous, present perfect, present perfect continuous, simple past, past continuous, past perfect, past perfect continuous, simple future, future continuous, future perfect, and future perfect continuous. I will try to explain them as easy as possible.
Many learners failed or understood nothing about tenses because they think twice in the same time, I mean think about the form of tenses and the function. That is why, for the first time I will only explain how to form the sentence with each tense. So, do not be confused if you find some words are wrong in function but correct in order. And after you know well how to make a sentence I will explain the function of tenses in the easiest way.
