Hızlı Öğren
Must, can't, might ve could, şu anki bir durum hakkında ne kadar emin olduğunu gösterir; seçimi eldeki kanıt belirler.
Aklında tut
- Must neredeyse kesin olumlu tahmindir: the lights are on, someone must be inside.
- Can't neredeyse kesin imkânsızlıktır: she can't be thirty, she looks eighteen.
- Might, may ve could gerçek bir ihtimaldir: take an umbrella, it might rain.
Örnekler
- 1The office lights are on and his bicycle is parked outside; David must be inside.
- 2That luxury sports car can't belong to a high school student; it costs a fortune.
Kaçınılması Gereken Yaygın Tuzak
İmkânsızlık için must not kullanma: it can't be true doğru, it must not be true yanlış. Must not tahmin değil yasak bildirir.

Kural
İpuçlarından çıkarım
Modals of present deduction, eldeki ipuçlarına bakarak şu anki bir durum hakkında mantıklı bir çıkarım yapmayı sağlar. Türkçede bunu “-malı”, “-mış olmalı”, “olamaz” ve “olabilir” gibi ifadelerle yaparız: “Işıklar yanıyor, evde olmalı.” İngilizcede çıkarımın ne kadar kesin olduğunu modal fiil gösterir.
Must: neredeyse kesin
(1) Must: neredeyse kesin olumlu çıkarım. Kanıtlar tek bir sonuca işaret ediyorsa must kullanılır: The lights are on and his car is outside; David must be at home. She has studied architecture for six years; she must know a lot about buildings.
Can't: imkânsız
(2) Can't: neredeyse kesin olumsuz çıkarım, yani imkânsızlık. Kanıtlar bir ihtimali tamamen dışlıyorsa can't kullanılır: That man can't be sixty; he looks thirty. She can't be at home; I've just seen her at the supermarket.
Might, may, could: ihtimal
(3) Might, may ve could: gerçek bir ihtimal, ama kesin kanıt yok. Why is the train late? There might be a problem with the signals. Don't touch that wire; it could be dangerous. Take an umbrella; it may rain this afternoon.
Yapı
Hepsinin yapısı aynıdır: özne + modal + fiilin yalın hâli. He must be tired, She can't know about it. Şu anda süren bir durum için modal + be + -ing kullanılır: She isn't answering; she must be driving.

How to read this B1 topic
At B1, grammar links ideas: condition, result, reported meaning, experience, and narrative order.
1. Name the relationship
Ask whether the sentence gives a condition, contrast, cause, report, or result.
If it rains, we will stay home.
2. Separate time from aspect
Finished event, visible result, duration, and background action use different forms.
I had left before she arrived.
3. Test both clauses
In complex sentences, the second half often proves the first half.
I wish I knew.
Modal verbs
Modals are followed by the base verb. They do not take third-person -s.
| Meaning | Present / future | Past or perfect reference | Example |
|---|---|---|---|
| ability | can | could / was able to | She can swim. |
| obligation | must / have to | had to | We must leave. |
| advice | should | should have + participle | You should rest. |
| deduction | must / might / can't | must have / might have / can't have | He must be tired. |
Contrasts that often decide the answer
Event or background
Simple forms move events forward; continuous forms show an action in progress.
I left while she was talking.
Fact or stance
Modals, hedges, and reporting structures show how certain or responsible the speaker sounds.
This may indicate a problem.
Clause or compressed phrase
Advanced writing often compresses full clauses into participle, noun, or prepositional phrases.

İstisnalar
İmkânsızlık bildirirken must not değil, can't kullanılır: He can't be French; he doesn't speak a word of it. Must not çıkarım değil yasak bildirir: You mustn't park here. Could olasılık bildirir (It could be true), ama olumsuzu couldn't imkânsızlık bildirir (It couldn't be true, yani can't be true ile aynı anlam). Genel bir olasılıktan söz ederken can kullanılabilir (Winters here can be very cold), ama şu anki belirli bir durum hakkında tahminde bulunurken can kullanılmaz.
