Simple future-will-and-be-going-to

Simple Future has two different forms in English: "will" and "be going to." Although the two forms can sometimes be used interchangeably, they often express two very different meanings. These different meanings might seem too abstract at first, but with time and practice, the differences will become clear. Both "will" and "be going to" refer to a specific time in the future.

We use the simple future for:

·  A decision at the moment of speaking:
A: 'I'm cold'.
B: 'I will close the window'.

·  Prediction based on opinion:
I think the Conservatives will win the next election.

·  A future fact:
The sun will rise at 7am.

·  Promises / requests / refusal / willingness:
I'll help you with your work.
Will you give me a hand?
I will give up smoking!

·  In the same way as the future continuous, but with state verbs:
I'll be at the station when you arrive.

·        To request information:

Will Tom ever pay you back?

Forms:

	Subject	auxiliary		Main verbs
Positive	I	Will		open	The door.

Negative	She/he/it	will	not	help	Me.

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

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	he won't
She will not	She won’t
It will not	It won’t
We will not	We won’t
They will not	They won’t

Use of be going to:

FORM Be Going To

[am/is/are + going to + verb]
Examples:

• You are going to meet Sarah tonight.
• Are you going to meet Sarah tonight?
• You are not going to meet Sarah tonight.

We use be going to+infinitive to talk about future plans:

Example : we are going to drive around Australia

We use 'going to' when we want to make a prediction based on evidence we can see now.

• Look out! That cup is going to fall off.
• Look at those black clouds. It's going to rain soon.
