Simple Future

This tense tells us about an action which has not occurred yet and will occur after saying or in future

Rule – Will/Shall + Verb (Ist form) In Future Tense helping verb ‘Shall’ is used with ‘I’ and ‘We’. Helping verb ‘Will’

is used with all others. When you are to make a commitment or warn someone or emphasize something, use of 'will/shall' is reversed. ‘Will’ is used with ‘I’ & ‘We’

and 'shall' is used with others.

In general speaking there is hardly any difference between 'shall & will' and normally ‘Will’ is used with all.

Now, let us use this rule in various forms of sentences; 1.  Positive / Affirmative Sentences –

Subject + Will/Shall + Verb (Ist form) + Object + (.) She will write a letter.

2.  Negative Sentences-

Subject + Will/Shall + Not + Verb (Ist form) + Object + (.) She will not write a letter.

3.  Interrogative Sentences-

Will/Shall + Subject + Verb (Ist form) + Object + (?) Will she write a letter?

4.  Interrogative Negative Sentences-

Will/Shall + Subject + Not + Verb (Ist form) + Object + (?) Will she not write a letter?

Future Continuous Tense

It is used to express an ongoing or continued action in future.

e.g. He will be distributing sweets in temple tomorrow at 12 o'clock.

In the example, the action will start in future (tomorrow) and action is thought to be continued till sometime in future.

We use the future continuous to talk about something that will be in progress at or around a time in the future.

Rule: Will/Shall + Be + Verb (Ist form) + Ing Now, let us use this rule in various forms of sentences; 1.  Positive / Affirmative Sentences –

Subject + Will/Shall + Be + Verb (Ist form) + Ing + Object + (.) She will be writing a letter.

Future Perfect Tense

It is used to express an action which will happen/occur in future and will be completed by a certain time in future.

We use the future perfect to say that something will be finished by a particular time in the future.

e.g. They will have shifted the house by Sunday morning.

Rule: Will/Shall + Have + Verb (3rd form) Now, let us use this rule in various forms of sentences; 1.  Positive / Affirmative Sentences –

Subject + Will/Shall + Have + Verb (3rd form) + Object + (.) She will have written a letter.

2.  Negative Sentences-

3.  Interrogative Sentences-

Will/Shall + Subject + Have + Verb (3rd form) + Object + (?) Will she have written a letter?

4.  Interrogative Negative Sentences-

Will/Shall + Subject + Not + Have + Verb (3rd form) + Object + (?) Will she not have written a letter?

Future Perfect Continuous Tense It is used to talk about actions that will commence at a fix time in future and will continue for some time in future.

If there is no time reference, then it is not a Future perfect continuous tense.

Without continued time reference, such sentences are Future Continuous Tense.

Continued time reference only differentiates between Future Continuous Tense and Future Perfect Continuous Tense.

The future perfect progressive emphasize the duration of an activity that will be in progress before another time or event in the future.

e.g. This time tomorrow, I will be enjoying the cricket match in the stadium.

e.g. They will be staying for a week’s The future perfect progressive emphasize the duration of an activity that will be in progress before another time or event in the future.
