We use the verb tense to indicate the particular time of an action,
event or condition. When we want to describe a number of actions or
events, we will use different tenses in a sentence, a paragraph and
a whole composition. Changes in verb tense can help readers understand
the relationships among various events. But if we make too many shifts
in tenses, it will cause misunderstanding. We usually keep one tense
as the main tense and indicate changes of time by changing tenses
relative to the main tense.

is more important.
