Structure
The use of tenses in English may be quite complicated, but the structure of English tenses is actually very simple. The basic structure for a positive sentence is:
subject + auxiliary verb + main verb
An auxiliary verb is used in all tenses. (In the simple present and simple
past tenses, the auxiliary verb is usually suppressed for the affirmative, but
it can and does exist for intensification.) The following table shows the 12
tenses for the verb to work in the active voice.
