Functions of 'To Be'

2.

Main Verbs

1. 'To Be' as an Auxiliary Verb

Use

The verb 'to be' as an auxiliary verb has no specific meaning and it is used to show the tense or voice of the main verb. There are two ways in which the verb 'to be' is used:

'To be' is used in to make a present participle and form a progressive aspect. For example:

Example

I am learning French.

'Am' here makes a present continuous tense.

She was looking at the mirror.

'Was' here makes a past continuous tense.

They will be doing exercises.

'Be' here makes a near-future tense.

The verb 'to be' as an auxiliary verb is used in the passive voice. For example:

Example

I was told to be there.

'Was' here makes a simple past passive.

Those books will be sold later.

'Be' here makes a simple future passive.

Position in a Sentence

The position of the auxiliary verb 'be' is changed in a sentence depending on the presence of the verb have or modal verbs. In other words, the tense, then the voice of the verb is prioritized. Look:

Example

They are doing exercise.

'Doing' is the main verb and the auxiliary verb 'are' comes before it.

It has been made.

The auxiliary verb 'been' is placed after 'has' because 'has' makes the perfect tense.

_Has it been made? _ No, it hasn't been made yet.

As you see, we make questions and negations with 'has.'

It will have been made.

The modal verb comes before 'have been.'
