Future Forms in Formal Writing, Conditionals, and Reported Speech

What this session covers

Future forms in English do not only appear in straightforward statements about what will happen. They also play important roles in conditional sentences, in reported speech, and in formal writing — where the choice of future form carries information about register, certainty, and relationship. Understanding how future forms shift in reported speech, how they function in first and zero conditionals, and what formal alternatives exist for will in professional writing is what distinguishes a teacher with deep grammatical knowledge from one who has only learned the basics.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
When you write a formal letter or official document in English, do you always use 'will' for the future, or do you sometimes use 'shall', 'be to', or 'be due to'? Do you know why any of these might be preferable in certain contexts?
Q2
Which of these have you seen your learners struggle with: reporting someone's future statement correctly (e.g. reporting 'I will come' as 'she said she would come'), using the correct tense in the if-clause of a first conditional, or choosing between formal future alternatives in professional writing?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
Direct speech: The head teacher said, 'The inspector will visit on Thursday.'
Reported speech: The head teacher said that the inspector would visit on Thursday.

Direct speech: She told us, 'I will send the report by Friday.'
Reported speech: She told us that she would send the report by Friday.

What happens to 'will' when it appears in reported speech? Is there a pattern?

In reported speech, future forms backshift just like other tenses. Will shifts back to would. This is because the reporting is happening after the original statement — the speaker is looking back at something that was said in the past. When the head teacher spoke, she used 'will visit' — a genuine future intention. When we report it later, that future intention from the past becomes 'would visit' — a future-in-the-past form. Would is the past form of will in this context, not a conditional marker. This distinction is worth explaining explicitly: 'would' in reported speech is not a conditional — it is reported future. Learners who understand this are much less likely to leave 'will' unchanged when reporting speech.

2
First conditional: If it rains tomorrow, we will hold the assembly inside.
Zero conditional: If it rains, the ground gets wet.
Second conditional: If it rained, we would hold the assembly inside.

Look at the verb in the if-clause of each sentence. What tense is used? Does 'will' ever appear in an if-clause?

In the first conditional (a real, possible future situation), the if-clause uses present simple — not will. 'If it rains' not 'If it will rain.' The will appears only in the result clause: 'we will hold'. This is one of the most persistent errors learners make: putting will in the if-clause. The rule is clear: in first conditionals, the if-clause uses present simple even though the meaning is future. In zero conditionals (general truths and cause-effect), both clauses use present simple: 'If it rains, the ground gets wet.' Will never appears in the if-clause of any standard conditional type. Teachers who understand this can explain the error clearly and prevent it.

3
Informal: 'We will send you the results soon.'
Formal letter: 'We shall forward the results to you at the earliest opportunity.'

Formal announcement: 'The inspector is to visit all schools in the district next term.' (be to)
Official schedule: 'The results are due to be released on 15th March.' (be due to)
Firm commitment: 'This matter is to be resolved before the end of term.' (be to — obligation)

Look at the words used instead of 'will' in the formal examples. What do 'shall', 'be to', and 'be due to' add — in terms of meaning or register?

English has several formal alternatives to will for future reference. 'Shall' (first person formal) is used in official British English for strong future commitments and legal language: 'We shall respond within ten days.' 'Be to' expresses something officially arranged or formally required: 'The teachers are to submit lesson plans by Monday.' It is common in official instructions and announcements. 'Be due to' signals a scheduled event, often with a specific time: 'The inspector is due to arrive at 9 a.m.' These forms are rarely taught at basic level but appear regularly in the kind of formal professional writing that teachers encounter and produce. Knowing them allows teachers to write with greater precision and authority.'

The Pattern — What You Just Discovered

Future forms behave in specific ways in three important contexts: in reported speech (will backshifts to would), in conditional sentences (will never appears in the if-clause), and in formal writing (will can be replaced by shall, be to, or be due to for different shades of formality and obligation). Understanding these uses gives teachers the depth to explain future forms accurately at every level.
FormUse / MeaningExample
Context Form used Example
Reported speech (future → past) will → would 'I will come.' → She said she would come.
First conditional if-clause Present simple (NOT will) If it rains tomorrow, we will cancel the sports day.
First conditional result clause will + base form ...we will cancel the sports day.
Zero conditional (both clauses) Present simple If students miss lessons, they fall behind.
Formal future: strong commitment shall (first person) We shall respond to your complaint within five days.
Formal future: official arrangement be to + base form All teachers are to submit their reports by Friday.
Formal future: scheduled event be due to + base form The inspector is due to arrive at 9 a.m. on Monday.
Special Rule / Notes

WOULD IN REPORTED SPEECH VERSUS WOULD IN CONDITIONALS
A common confusion for learners (and some teachers) is the use of 'would' in two very different grammatical contexts: reported speech and second conditionals. In reported speech, 'would' is simply the past form of 'will' — it reports a future intention from the past: 'She said she would come' (reported future). In second conditionals, 'would' expresses an imagined present or future situation: 'If I had more time, I would prepare better' (hypothetical). These are the same word but with completely different functions. Being able to explain this distinction clearly is a mark of grammatical depth.

WILL IN FIRST CONDITIONAL IF-CLAUSES: THE EXCEPTION
While will is not used in the if-clause of first conditionals, there is one exception: when 'will' is used to express willingness rather than futurity, it can appear in an if-clause. 'If you will help me, I will finish faster.' Here 'will' means 'are willing to' — it is a politeness device, not a future marker. This is a formal, somewhat old-fashioned usage. At this level it is enough to flag it as an exception rather than teach it as a pattern.

SHALL IN QUESTIONS: OFFERS AND SUGGESTIONS
In British English, 'shall' is used in first-person questions to make offers and suggestions: 'Shall I open the window?' 'Shall we begin?' These are not future statements but present offers and suggestions. This is a separate use from 'shall' as a formal future marker ('We shall respond within five days'). Both uses exist, and teachers who know both are better placed to explain them when learners ask.

KEY QUESTIONS FOR FUTURE FORMS IN COMPLEX CONTEXTS In reported speech: - Did the original speaker use 'will'? → Report it as 'would'. - Is 'would' here a conditional or a reported future? → Ask: was this said in the past as a future intention? If yes, it is reported future, not conditional. In conditionals: - Is the if-clause expressing a real, possible future condition? → Present simple in the if-clause (never will). - Is the if-clause expressing an always-true cause-effect? → Present simple in both clauses (zero conditional). - Is 'will' in the if-clause? → This is almost always an error — remove it. In formal writing: - Is this a strong formal commitment in first person? → Consider 'shall'. - Is this an officially arranged requirement? → Consider 'be to'. - Is this a scheduled event with a specific time? → Consider 'be due to'. - Is the context informal? → Plain 'will' is appropriate.

Common Student Errors

She said she will attend the meeting.
She said she would attend the meeting.
WhyIn reported speech, will backshifts to would. The original statement was 'I will attend' — reported as 'she would attend'.
If it will rain tomorrow, we will cancel sports day.
If it rains tomorrow, we will cancel sports day.
WhyIn first conditional sentences, the if-clause uses present simple — never will. Will appears only in the result clause.
If you heat water, it will boil.
If you heat water, it boils.
WhyThis is a zero conditional — a general scientific truth. Both clauses use present simple. Will is not used in zero conditionals.
The inspector will be due to arrive at 9 a.m.
The inspector is due to arrive at 9 a.m.
Why'Be due to' is already a future expression — it does not need 'will' added before it. Use the correct form of 'be' (is/are) directly before 'due to'.
We shall to submit the report by Friday.
We shall submit the report by Friday.
Why'Shall' is a modal verb and is followed directly by the base form — never 'to + verb'. The same rule applies to shall as to will and other modals.

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence has one error. Write the correct sentence and explain the mistake.

She told the parents that she will contact them before the end of the week.
Write the correct sentence:
Explain why it is wrong:
She told the parents that she would contact them before the end of the week.
In reported speech, will backshifts to would. The original statement was 'I will contact you' — reported as 'she would contact them'.
If it will be too hot tomorrow, we will hold the lesson outside in the shade.
Write the correct sentence:
Explain why it is wrong:
If it is too hot tomorrow, we will hold the lesson outside in the shade.
In first conditional sentences, the if-clause uses present simple — never will. 'Will be' should be 'is'.
We shall to inform all parents of the new policy by the end of this term.
Write the correct sentence:
Explain why it is wrong:
We shall inform all parents of the new policy by the end of this term.
'Shall' is a modal verb — it is followed directly by the base form without 'to'. Remove 'to': 'shall inform'.
If teachers give clear feedback, students will improve their work. (intended as a general truth, not a specific prediction)
Write the correct sentence:
Explain why it is wrong:
If teachers give clear feedback, students improve their work.
For a general truth or always-true cause-effect relationship, use the zero conditional: present simple in both clauses. If 'will improve' is used, it becomes a first conditional (a specific prediction), which changes the intended meaning.

Classroom Teaching Sequence

Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.

0 / 5 done
1

STEP 1 — REPORTED FUTURE PRACTICE (8 minutes): Tell learners that a colleague told you several things yesterday. Read out five direct speech sentences using will. Ask learners to report each one correctly using would. For example: 'She said: I will prepare new materials.' → 'She said she would prepare new materials.' Do this as a quick oral activity first, then ask learners to write two examples of their own.

2

STEP 2 — THE FIRST CONDITIONAL RULE (8 minutes): Write on the board: IF + _____ , + WILL + base form. Ask learners what goes in the blank. Guide them firmly to: present simple. Write three first conditional sentences — two correct, one with 'will' in the if-clause (the error). Ask learners to identify the error and correct it. Explain: 'Will in the if-clause is one of the most common future tense errors — and once you know the rule, it is easy to spot and fix.'

3

STEP 3 — FIRST VERSUS ZERO CONDITIONAL (7 minutes): Write two versions of a sentence on the board: 'If it rains, the students will come inside.' (first conditional — specific prediction) and 'If it rains, the students come inside.' (zero conditional — general routine). Ask learners: 'What is the difference in meaning?' Establish that first conditionals are specific future predictions; zero conditionals are general truths. Give three more pairs and ask learners to identify which is which.

4

STEP 4 — FORMAL FUTURES (8 minutes): Write three plain will sentences on the board from different professional contexts — a formal letter, an official notice, and a school announcement. Ask learners: 'Could any of these be made more formal?' Introduce 'shall', 'be to', and 'be due to' with clear examples. Ask learners to rewrite one sentence using each formal alternative. Discuss as a class.

5

STEP 5 — PRODUCE AND REFLECT (9 minutes): Ask learners to write: (1) one sentence reporting something a colleague said this week (reported speech with would), (2) one first conditional sentence about a real possibility in their school, and (3) one formal future sentence using 'be to' or 'be due to' about a real school event. Share with a partner. Give feedback on whether the forms are accurate and appropriate to the context.

Ready-to-Use Classroom Materials

Use directly in class — copy, adapt, or read aloud. No printing needed.

1 Report the Meeting (reported speech practice)
Tell learners that they are reporting what was said at a staff meeting last week. Read out five direct speech statements using will. Learners report each one correctly with would. Then ask learners to produce two reporting sentences about things their own head teacher or colleagues have said recently.
Example sentences
Direct: 'I will observe three lessons next week.' → Reported: She said she would observe three lessons the following week.
Direct: 'The school will receive new textbooks next term.' → Reported: He said the school would receive new textbooks the following term.
Direct: 'We will discuss the results at the next meeting.' → Reported: She told us we would discuss the results at the next meeting.
2 If-Clause Error Hunt
Write ten conditional sentences on the board — a mix of correct first conditionals, correct zero conditionals, and sentences with will incorrectly placed in the if-clause. Ask learners to identify all errors and correct them. This activity trains quick recognition of the most common future tense error in conditional sentences.
Example sentences
1. If the inspector will visit, we will be ready. (✗ → If the inspector visits)
2. If students practise every day, they improve. (✓ — zero conditional)
3. If it will rain, we will cancel the event. (✗ → If it rains)
4. If you heat ice, it melts. (✓ — zero conditional)
5. If the head teacher approves the plan, we will start next week. (✓ — first conditional)
3 Make It Formal (register conversion)
Provide a set of informal or neutral future statements. Ask learners to rewrite each one using a more formal alternative — shall, be to, or be due to — as appropriate. Discuss as a class which alternative fits best and why. This builds awareness of register in professional writing.
Example sentences
Informal: 'We will send you the information soon.'
Formal: 'We shall forward the information to you at the earliest opportunity.'
Informal: 'All teachers need to submit lesson plans by Monday.'
Formal: 'All teachers are to submit lesson plans by Monday morning.'
Informal: 'The inspector is coming at 9 a.m. next Tuesday.'
Formal: 'The inspector is due to arrive at 9 a.m. on Tuesday 15th.'

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Practise reporting speech regularly — take something said in a real meeting and report it to a colleague using would. This makes the backshift automatic.
Train yourself to notice will in if-clauses — in your own writing and in learner writing — and remove it immediately. This single habit will eliminate one of the most common errors.
Explore formal alternatives to will in official documents you receive: school circulars, government letters, official announcements. Notice how 'be to', 'be due to', and 'shall' are used.
Help your learners understand that 'would' in reported speech is not a conditional — it is simply the past form of will. This explanation prevents a common confusion.
When teaching conditionals, always write the if-clause formula clearly: IF + PRESENT SIMPLE (never will). Seeing it written this way helps learners remember the rule.
What is the one change you will make next time you teach this grammar point?

Key Takeaways

1 In reported speech, will backshifts to would — 'She said she would attend' reports an original statement of 'I will attend'.
2 In first conditional sentences, the if-clause uses present simple — never will. Will appears only in the result clause.
3 In zero conditional sentences (general truths), both clauses use present simple — will does not appear.
4 Formal written English uses 'shall' for strong first-person commitments, 'be to' for official arrangements and requirements, and 'be due to' for scheduled events.
5 Would in reported speech is a past form of will — it reports a future intention, and should not be confused with would in second conditionals, which expresses an imagined situation.
