Impornant notice
editMany English learners worry too much about tense. If you stopped 100 native English speakers in the street and asked them about tense, 1 of them might give you an intelligent answer - if you were lucky. The other 99 would know little about terms like "past perfect" or "present continuous". And they would know nothing about aspect, voice or mood. But they can all speak fluent English and communicate effectively. Of course, for ESL it helps to know about tenses, but don't become obsessed with them. Be like those native speakers! Speak naturally!
Additional implications
edit- Some grammarians consider that strictly-speaking there are only two English tenses. Others argue six or other quantities. For the sake of simplicity, Learners of English as a Foreign or Second Language are usually taught that - taking into account aspect and future modals - there are 12 tenses in English.
