Key Takeaways Explain This Topic AI

Use going to for plans and predictions based on present evidence; use will for spontaneous decisions, offers, promises, and neutral future facts at A2

Can/could express ability and permission; could is also a polite request form common in Part 6 emails

Must and have to express obligation; mustn't means prohibition; don't have to means no obligation—not the same as mustn't

Should gives advice; would like is the polite way to state wants and invitations

Future and modal forms feed Writing content points, Speaking interactive phrases, Listening detail, and open cloze auxiliaries such as will, can, and to

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

Subject Affirmative Negative Question

I am going to + base am not going to + base Am I going to…?

he/she/it is going to + base isn't going to + base Is she going to…?

you/we/they are going to + base aren't going to + base Are they going to…?

Will

Form Example

Affirmative I will (I'll) call you.

Negative I will not (won't) be late.

Question Will you come?

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

Meaning contrast (exam-useful)

Use Prefer Example

Personal plan / intention going to I'm going to visit my uncle on Sunday.

Prediction from evidence now going to Look at those clouds. It's going to rain.

Spontaneous decision will The phone's ringing. I'll answer it.

Offer will I'll carry your bag.

Promise will I'll send the photos tonight.

Neutral future fact / timetable support will (or present simple timetable) The shop will open at nine. / It opens at nine.

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

  • Trap Wrong Better
  • will after to I want will go I want to go / I will go
  • Double future I will going to help I will help / I'm going to help
  • s after will She will goes She will go

Plan stated as weak present only I go to the cinema tomorrow (possible but vague) I'm going to the cinema tomorrow / I'm going to go…

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).

Modal Core A2 meanings Example

can ability; permission; possibility (simple) I can swim. Can I open the window?

could past ability (basic); polite permission/request I could ride a bike when I was six. Could you help me?

must strong obligation / necessity (speaker’s rule) You must wear a seatbelt.

have to obligation (often external rule) I have to wear a uniform at school.

mustn't prohibition You mustn't smoke here.

don't have to no obligation You don't have to bring food.

should advice You should sleep more.

would like polite want / invitation I would like a tea. Would you like to come?

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

Force Phrase

Neutral permission ask Can I use your phone?

More polite request Could you open the window, please?

Giving permission Yes, you can. / Of course.

Refusing Sorry, you can't.

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

Form Meaning Example

must necessary / required (often speaker feels it strongly) You must tidy your room.

have to necessary because of rules/facts Students have to wear badges.

mustn't not allowed You mustn't use your phone in the exam.

don't have to not necessary (you can if you want) You don't have to wear a tie.

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

Form Example

Advice You should take an umbrella.

Negative advice You shouldn't eat so many sweets.

Question Should I call her?

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

Function Pattern Example

Want a thing would like + noun I'd like a water, please.

Want an action would like to + base I'd like to book a table.

Invite Would you like to + base? Would you like to come to my party?

Offer Would you like + noun? Would you like some cake?

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.

Permission / Ability / Advice / Obligation Map

  • Function Best A2 tools
  • Ability can / can't / could

Ask permission Can I…? / Could I…?

  • Give/refuse permission You can… / You can't…
  • Obligation must / have to / had to
  • Prohibition mustn't / can't (context)
  • No obligation don't have to
  • Advice should / shouldn't
  • Polite want/invite would like (to)
  • Future plan going to / present continuous
  • Offer/promise/spontaneous future will
  • Exam Task Connections
  • Writing Part 6

Typical content points and natural forms:

  • Content need Useful form
  • Say your plan I'm going to… / I'll…

Invite Would you like to…? / Do you want to…?

Request Can/Could you…, please?

  • Give a rule-like instruction You must… / Please don't…
  • Soft suggestion You should… / Let's…
  • 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.”

Integrated Error Traps

  • Trap Wrong Correct
  • Modal + to (except ought to , rare at A2 focus) You must to go You must go
  • Modal + -s She can sings She can sing

mustn't for “not necessary” You mustn't pay if you don't want (if meaning is optional) You don't have to pay if…

  • don't have to for ban You don't have to smoke here (as a ban) You mustn't smoke here
  • Past of must for obligation I musted work I had to work
  • will + to I will to help I will help
  • Plan without to I'm going visit I'm going to visit
  • would like without to before verb I'd like go I'd like to go
  • Mini Production Bank (Memorise and Reuse)

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

Write six Part 6 micro-sentences: plan, invite, request, apologise + future fix, advice, rule.

Contrast cards: mustn't vs don't have to with real school signs.

Speaking pair drill: only answer with should / could / going to / will for two minutes.

Cloze hunt: circle to after going / have / like / want .

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.
