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.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
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.
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.
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.'
| Form | Use / Meaning | Example |
|---|---|---|
| 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. |
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.
Choose the correct form for each gap. Pay attention to the grammatical context — reported speech, conditional, or formal writing.
Each sentence has one error. Write the correct sentence and explain the mistake.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
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.
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.'
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.
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.
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.
