Question

What is the difference between simple, perfect, continuous, and perfect continuous of the past, present, and future? Please give examples or sites if you can.

Answer 1

Answer:

We use the present perfect tense to talk about things where there is a connection between the past and the present.

He’s written 16 books.

He started writing books at some time in the past. So far, he has written 16 books. He may write more books.

As well as the present perfect simple, we can use the present perfect continuous tense to talk about events with a connection to the present.
