10.2 Future Forms, Modals and Obligation

10.2 Future Forms, Modals and Obligation

Quick Answer: For A2 future meaning, use going to for plans and evidence-based predictions (I'm going to study tonight) and will for spontaneous decisions, offers, and promises (I'll help you). Use can/could for ability and permission, must/have to for obligation, mustn't for prohibition, should for advice, and would like for polite wants. These forms power emails, speaking requests, and many open cloze gaps.

After present and past control, the next productivity jump is future forms and modals. A2 Key does not demand every advanced modal meaning. It does demand that you can plan, offer, permit, forbid, advise, and invite with short accurate phrases.

Future Forms at A2: Going to vs Will

Form tables

Going to

Will

After will/won't, use the base form: will go, not will goes / will went.

Meaning contrast (exam-useful)

Present continuous for arrangements

You already met this in 10.1. Fixed personal arrangements often use continuous:

• We are meeting Sam at the station at five.

This overlaps with going to. Both can be correct. In Writing Part 6, either I'm going to meet… or I'm meeting… is usually fine if the meaning is a clear plan.

Future error traps

Exam links — future

• Writing Part 6: content points about next weekend, invitations, and plans → going to / present continuous / will for offers.
• Speaking Part 2: discussing options → I think we should… / I'm going to choose… / I'll take the blue one.
• Open cloze: gaps for will, to (going ___ visit → to), is/are before going.
• Listening: final plan often appears after a change of mind—I'll take the later train vs earlier option.

Modals: The A2 Core Set

Modals are special verbs: modal + base form (no -s on the main verb, no to after most of these).

Form reminders

• ✅ She can cook. ❌ She cans cook. ❌ She can to cook.
• ✅ He must go. ❌ He must to go. ❌ He must goes.
• have to is different: it uses normal do/does/did support: Does she have to work? She doesn't have to work.
• would like often appears with to + base: I would like to visit Paris.
• Short forms: I'd like, I'll, won't, can't, mustn't, shouldn't

Ability and Permission: Can / Could

Ability

• Present ability: I can speak a little Spanish.
• Past ability (simple A2): I could swim when I was five.
• Negative ability: I can't drive. I couldn't open the door yesterday.

Permission and requests

Writing Part 6 gold phrases

• Can you bring a cake, please?
• Could you tell me the time of the class?
• Can I come with you?

If a content point says ask, a modal question is often the cleanest completion.

Obligation and Prohibition: Must, Have to, Mustn't, Don't have to

Side-by-side meanings

The high-cost trap: mustn't ≠ don't have to

• You mustn't park here. = Forbidden. Parking is wrong.
• You don't have to park here. = Not necessary. You may park somewhere else; parking here is not required.

Candidates who translate from another language sometimes reverse these. In Reading Part 1 notices and Listening rules, the difference decides the answer.

Must vs have to at A2

Both can express obligation. Practical exam advice:

• Rules and school/work requirements → have to feels very natural: I have to start work at eight.
• Strong instruction / moral necessity → must: You must be careful.
• Past obligation → had to (not musted): Yesterday I had to stay late.

Open cloze watch: I have ___ finish this → often to (have to finish).

Advice: Should

Speaking Part 2 thrives on should:

• I think we should buy the red bag because it's cheaper.
• Maybe we shouldn't choose the expensive hotel.

Should is softer than must. Use it for recommendations, not for strict bans (mustn't).

Polite Wants: Would like

Compare with direct want: both are possible, but would like sounds more polite for teachers, neighbours, and service situations—useful for semi-formal Part 6 notes.

Exam Task Connections

Writing Part 6

Typical content points and natural forms:

Writing Part 7

Stories stay mostly past, but speech bubbles or thoughts can include modals: I must run! / I can't find my keys. Keep narrative tense consistent around them.

Speaking

• Part 1 future: What are you going to do after school?
• Part 2 collaboration: We could… / We should… / I'll choose…
• Repair phrases: Sorry, can you repeat that, please?

Open cloze

Common one-word targets:

• will / won't
• can / could
• to after have, want, would like, going
• not in must not / do not have to patterns (if single-word fit allows)

Listening / Reading notices

Signs: You must not enter. / Staff only. / Please do not feed the animals. Match meaning to mustn't / prohibition, not to “optional.”

Plans: I'm going to stay at home. We're going to take the bus.
Offers: I'll help you. I'll send the address.
Requests: Could you email me? Can you wait five minutes?
Advice: You should take a jacket. You shouldn't walk alone late.
Rules: You have to show your ID. You mustn't copy answers.
Polite want: I'd like to join the club. Would you like some water?

Practice Plan

1. Write six Part 6 micro-sentences: plan, invite, request, apologise + future fix, advice, rule.
2. Contrast cards: mustn't vs don't have to with real school signs.
3. Speaking pair drill: only answer with should / could / going to / will for two minutes.
4. Cloze hunt: circle to after going / have / like / want.
5. Transform: change I want pizza → I'd like a pizza, please.

Future and modals turn basic tense knowledge into social English—the language of arranging life with other people. That is exactly what A2 Key Writing and Speaking reward. Next, Section 10.3 builds comparison language and word order so your sentences stay natural as well as grammatical.
