This is Tom's agenda for next week:

• He is playing tennis on Monday afternoon

• He is going to the dentist on Tuesday morning
• He is having dinner with Ann on Friday

In all these examples, Tom has already decided and arranged (combinou / fez projectos) to do these things

• What time does the film begin?

• The train leaves Plymouth at 10.30 and arrives in London at 13.45.
• The football match starts at 8 o'clock

The examples above refer to: timetables (horários), programmes, etc

Usa-se o present continuous [ am, are, is  + - ing form]  quando nos queremos referir a coisas que já decidimos (ou combinámos, ou programámos)  fazer futuramente

Usa-se o present simple para falar de horários (de combóios, cinemas, etc)   ou  programas

• A: There's a film on television tonight. Are you going to     watch it?

• B: No, I'm too tired. I 'm going to have an early night.

• Look at those black clouds! It is going to rain.

• I feel terrible. I think I am going to be sick.

In these examples, people had already decided what to do in the future. They are talking about what they intend  to do.(tencionam fazer)

Here, peolpe say what they think will happen in the future, because there is something in the present situation that makes them sure about it

• When you return home, you'll notice a lot of changes.

• This time next year I'll be in Japan. Where will you be?

• When will you know your examination results?

• Tom won't pass this year. He hasn't studied.

• Oh, I've left the door open. I'll go and shut it.

• «What would you like to drink?»  «I'll have a lemonade, please.»

• I'm too tired to walk home. I think I'll get a taxi.

• I don't think I'll go out tonight. I'm too tired.

Here, people are just talking about the future.

There are no other intentions, predictions, etc

In these examples, people have decided what to do only at the time of speaking.

There was no previous intention (não havia uma intenção prévia)

Talking about future actions

Predicting the future

situation1: Helen's bike has a flat tyre. She tells her father.

Helen: My bycicle has a flat tyre. Can you repair it for me?

Father: Okay, but I can't do it now. I'll repair it tomorrow.

• Do you think Tom will get the job?

• Oh dear, it's already 4 o'clock. We're going to be late for our appointment. (the appointment was probably at 4 o'clock)

• Look at those black clouds! It's going to rain. (the clouds are there now)

• I feel terrible. I think I'm going to be sick. (I feel terrible now)

situation 2: Later, Helen's mother speaks to her husband.

Mother: Can you repair Helen's bycicle? It has a flat tyre.

Father:  Yes, she told me. I'm going to repair it tomorrow.

  Study this example situation: 

Tom is a football fan and there is a football match on television this evening. The match begins at 7.30 and ends at 9.15. Ann wants to come and see Tom this evening and wants to know what time to come:

Ann: Is it all right if I come at about 8.30?

Tom: No, don't come then. I' ll be watching  the match on TV. (estarei a ver o jogo)

Ann: Oh. Well, what about 9.30?

Tom: Yes, that' ll be fine. The match  will have finished  by then. (o jogo já terá acabado nessa altura)

Usa-se will be doing (future continuous) para dizer que estaremos a fazer qualquer coisa num determinado momento do futuro.

Usa-se will have done (future perfect) para dizer que uma coisa já terá acontecido ou acabado antes de um determinado momento do futuro.

Nota:  will be doing também pode usar-se  para falar de coisas que já estão decididas ou já foram planeadas:

• I'll be going to the city centre later. Can I get you anything?

• «Will you be using your car this evening?»    «No, you can take it.»
