Importance of the Auxiliary Verb

In English, tenses are formed by conjugating an auxiliary verb plus a standard form of the principle verb (the base form, the gerund form, or the past participle form). It is import to focus on the variations in the auxiliary verb to properly use English tenses.

Symbols Used:

S (subject)
Aux (auxiliary verb)
O (objects)
? (question word, i.e., who, what when, etc.)

Construction:

In general, using the following patterns to construct sentences in active sentences.

Positive: S + Verb + O
Negative:S + Aux + Verb + O
Question:(?)+ Aux + S + Verb + (O)

Past Simple

Use the past simple when an action is done at a SPECIFIED point in time in the past.

Auxiliary: DID
