Answer:
Tenses and their functions
The table below gives an overview of some of the basic functions of tenses and aspects. Tenses locate an event in time, while aspects communicate durations and relationships between events that happen at different times.
Tense communicates an event’s location in time. The different tenses are identified by their associated verb forms.
There are three main tenses: past, present, and future. In English, each of these tenses can take four main aspects: simple, perfect, continuous (also known as progressive), and perfect continuous. The perfect aspect is formed using the verb to have, while the continuous aspect is formed using the verb to be.
In academic writing, the most commonly used tenses are the present simple, the past simple, and the present perfect
