*Facts or GeneralizationsThe Simple Present can also indicate the speaker believes that a fact was true before, is true now, and will be true in the future.

Simple Future

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.

FORM Will

[will + verb]

Examples:

You will help him later.

Will you help him later?

You will not help him later.

FORM Be Going To

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

Examples:

You are going to meet Jane tonight.

Are you going to meet Jane tonight?

You are not going to meet Jane tonight.

* "Will" to Express a Voluntary Action

"Will" often suggests that a speaker will do something voluntarily. A voluntary action is one the speaker offers to do for someone else. Often, we use "will" to respond to someone else's complaint or request for help. We also use "will" when we request that someone help us or volunteer to do something for us. Similarly, we use "will not" or "won't" when we refuse to voluntarily do something.

Examples:

I will send you the information when I get it.

I will translate the email, so Mr. Smith can read it.

Will you help me move this heavy table?

Will you make dinner?

I will not do your homework for you.

I won't do all the housework myself!

A: I'm really hungry.

B: I'll make some sandwiches.

A: I'm so tired. I'm about to fall asleep.

B: I'll get you some coffee.

A: The phone is ringing.

B: I'll get it.

*"Will" to Express a Promise

"Will" is usually used in promises.

Examples:

I will call you when I arrive.

If I am elected President of the United States, I will make sure everyone has access to inexpensive health insurance.

I promise I will not tell him about the surprise party.

Don't worry, I'll be careful.

I won't tell anyone your secret.

* "Be going to" to Express a Plan

"Be going to" expresses that something is a plan. It expresses the idea that a person intends to do something in the future. It does not matter whether the plan is realistic or not.

Examples:

He is going to spend his vacation in Hawaii.

She is not going to spend her vacation in Hawaii.

A: When are we going to meet each other tonight?

B: We are going to meet at 6 PM.

I'm going to be an actor when I grow up.

Michelle is going to begin medical school next year.

They are going to drive all the way to Alaska.

Who are you going to invite to the party?

A: Who is going to make John's birthday cake?

B: Sue is going to make John's birthday cake.

*"Will" or "Be Going to" to Express a Prediction

Both "will" and "be going to" can express the idea of a general prediction about the future. Predictions are guesses about what might happen in the future. In "prediction" sentences, the subject usually has little control over the future and therefore USES 1-3 do not apply. In the following examples, there is no difference in meaning.

Examples:

The year 2222 will be a very interesting year.

The year 2222 is going to be a very interesting year.

John Smith will be the next President.

John Smith is going to be the next President.

The movie "Zenith" will win several Academy Awards.

The movie "Zenith" is going to win several Academy Awards.

Future Continuous

Future Continuous has two different forms: "will be doing " and "be going to be doing." Unlike Simple Future forms, Future Continuous forms are usually interchangeable.

FORM Future Continuous with "Will"

[will be + present participle]

Examples:

You will be waiting for her when her plane arrives tonight.

Will you be waiting for her when her plane arrives tonight?

You will not be waiting for her when her plane arrives tonight.

FORM Future Continuous with "Be Going To "

[am/is/are + going to be + present participle]

Examples:

You are going to be waiting for her when her plane arrives tonight.

Are you going to be waiting for her when her plane arrives tonight?

You are not going to be waiting for her when her plane arrives tonight.

* Interrupted Action in the Future

Use the Future Continuous to indicate that a longer action in the future will be interrupted by a shorter action in the future. Remember this can be a real interruption or just an interruption in time.

Examples:

I will be watching TV when she arrives tonight.

I will be waiting for you when your bus arrives.

I am going to be staying at the Madison Hotel, if anything happens and you need to contact me.

He will be studying at the library tonight, so he will not see Jennifer when she arrives.

* Specific Time as an Interruption in the Future

Examples:

Tonight at 6 PM, I am going to be eating dinner.

I will be in the process of eating dinner.

At midnight tonight, we will still be driving through the desert.

We will be in the process of driving through the desert.

*In the Simple Future, a specific time is used to show the time an action will begin or end. In the Future Continuous, a specific time interrupts the action.

Examples:

Tonight at 6 PM, I am going to eat dinner.

I am going to start eating at 6 PM.

Tonight at 6 PM, I am going to be eating dinner.

I am going to start earlier and I will be in the process of eating dinner at 6 PM.

* Parallel Actions in the Future

When you use the Future Continuous with two actions in the same sentence, it expresses the idea that both actions will be happening at the same time. The actions are parallel.

Examples:

I am going to be studying and he is going to be making dinner.

Tonight, they will be eating dinner, discussing their plans, and having a good time.

While Ellen is reading, Tim will be watching television.

Notice "is reading" because of the time clause containing "while." (See Explanation Below)

Future Perfect

Future Perfect has two different forms: "will have done" and "be going to have done." Unlike Simple Future forms, Future Perfect forms are usually interchangeable.

FORM Future Perfect with "Will"

[will have + past participle]

Examples:

You will have perfected your English by the time you come back from the U.S.

Will you have perfected your English by the time you come back from the U.S.?

You will not have perfected your English by the time you come back from the U.S.

FORM Future Perfect with "Be Going To"

[am/is/are + going to have + past participle]

Examples:

You are going to have perfected your English by the time you come back from the U.S.

Are you going to have perfected your English by the time you come back from the U.S.?

You are not going to have perfected your English by the time you come back from the U.S.

It is possible to use either "will" or "be going to" to create the Future Perfect with little or no difference in meaning.
