English has several ways to talk about the future — each with a specific meaning.
🔹 will + infinitive :
• Predictions based on opinion or belief : I think it will rain tomorrow.
• Spontaneous decisions (at the moment of speaking) : 'I'm cold.' — 'I'll close the window.'
• Promises and offers : I will help you with your homework.
• Facts about the future : The sun will rise at 6am.
🔹 be going to + infinitive :
• Plans and intentions decided before speaking : I'm going to study medicine.
• Predictions based on evidence : Look at those clouds — it's going to rain.
🔹 Present Continuous (for future) :
• Fixed arrangements (time and place already decided) : We're meeting at 5pm tomorrow.
🔹 Key distinctions :
• will vs going to (prediction) : 'will' = personal opinion ; 'going to' = visible evidence
- 'I think she will pass.' (opinion)
- 'She has studied so hard — she's going to pass.' (based on evidence)
• going to vs present continuous : 'going to' = intention ; present continuous = firm arrangement
- 'I'm going to call him later.' (intention)
- 'I'm calling him at 3pm.' (arranged)
📝 Choose will, going to, or present continuous :
1. Look at that child — she _______ fall! → is going to fall (evidence)
2. 'The phone is ringing!' — 'Don't worry, I _______ get it.' → 'll get (spontaneous)
3. We _______ leave for Saint-Louis next Friday at 6am. → are leaving (arrangement)
4. Scientists predict that temperatures _______ rise by 2°C. → will rise (prediction)
5. She has decided — she _______ become a doctor. → is going to become (plan)
📝 Complete the dialogue :
A: Have you made plans for the weekend?
B: Yes, I _______ visit my cousins in Thiès. We _______ probably go to the market together.
A: Sounds fun! I think it _______ be hot — take some water!
→ B: am visiting / are going to go (or will go) / A: will be
Explain when to use 'will' vs 'going to' for predictions.
Correction
Use 'will' for predictions based on personal opinion or belief ('I think it will be a great year.'). Use 'going to' for predictions based on present visible evidence ('The sky is very dark — it's going to storm.').
Why is this wrong: 'I going to study tonight'?
Correction
'Going to' requires the verb 'to be': I AM going to study tonight. 'Going to' is not used alone as a verb — it needs the auxiliary 'be' conjugated to match the subject.
Transform using 'will': 'She is going to help me.' (make it a spontaneous offer)
Correction
She'll help me! (spontaneous, immediate decision). The meaning shifts from a pre-planned intention to a spontaneous offer.
Write a short paragraph about your plans after school, using all three future forms.
Correction
After school, I am meeting my study group at the library — we arranged it yesterday. I am going to prepare a revision plan for the whole term because the exams are approaching. I think it will be challenging, but I believe our teamwork will make a real difference.
What does 'shall' express and when is it used?
Correction
'Shall' is mainly used in offers and suggestions in British English (formal or polite contexts). 'Shall I help you?' (offer) / 'Shall we begin?' (suggestion). It is less common than 'will' in modern English.
