Simple Future Tense
I will sing

The simple future tense is often called will, because we make the simple future tense with the modal auxiliary will.

How do we make the Simple Future Tense?
The structure of the simple future tense is:

subject + auxiliary verb WILL + main verb
invariable base
will V1

For negative sentences in the simple future tense, we insert not between the auxiliary verb and main verb. For question sentences, we exchange the subject and auxiliary verb. Look at these example sentences with the simple future tense:

subject auxiliary verb main verb
+ I will open the door.
+ You will finish before me.
- She will not be at school tomorrow.
- We will not leave yet.
? Will you arrive on time?
? Will they want dinner?

When we use the simple future tense in speaking, we often contract the subject and auxiliary verb:

I will I'll
you will you'll
he will
she will
it will he'll
she'll
it'll
we will we'll
they will they'll

For negative sentences in the simple future tense, we contract with won't, like this:

I will not I won't
you will not you won't
he will not
she will not
it will not he won't
she won't
it won't
we will not we won't
they will not they won't

How do we use the Simple Future Tense?
No Plan
We use the simple future tense when there is no plan or decision to do something before we speak. We make the decision spontaneously at the time of speaking. Look at these examples:

Hold on. I'll get a pen.
We will see what we can do to help you.
Maybe we'll stay in and watch television tonight.
In these examples, we had no firm plan before speaking. The decision is made at the time of speaking.

We often use the simple future tense with the verb to think before it:

I think I'll go to the gym tomorrow.
I think I will have a holiday next year.
I don't think I'll buy that car.
Prediction
We often use the simple future tense to make a prediction about the future. Again, there is no firm plan. We are saying what we think will happen. Here are some examples:

It will rain tomorrow.
People won't go to Jupiter before the 22nd century.
Who do you think will get the job?
Be
When the main verb is be, we can use the simple future tense even if we have a firm plan or decision before speaking. Examples:

I'll be in London tomorrow.
I'm going shopping. I won't be very long.
Will you be at work tomorrow?
