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.)


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)

Auxiliary: DO


He often arrives late for work.
When do you do your homework?

Present Continuous

Use the present continuous when something is happening at or around the present moment in time. The present continuous is often used with 'now, at the moment, currently, today'.

What are you doing?
Go ahead and take it. She isn't reading that book currently.
