Modal fe’llar

Modal fe’llar asosiy fe’lga so‘zlovchining munosabatini qo‘shadi: qobiliyat (can), ruxsat (may), majburiyat (must), maslahat (should), ehtimollik (might). Bir xil gap modal fe’lga qarab butunlay boshqa ma’no oladi: He must be at home (aniq uyda), He might be at home (balki uyda), He can’t be at home (uyda bo‘lishi mumkin emas). Imtihonda modal fe’llar ma’no bo‘yicha tanlash, mustn’t va don’t have to farqi hamda o‘tmish haqidagi xulosalar (must have done) shaklida keladi.

§1. Modal fe’llarning umumiy qoidalari

Modal fe’llar boshqa fe’llardan grammatik jihatdan farq qiladi:

• Shaxsga qarab o‘zgarmaydi, -s olmaydi: She can swim. (✗ She cans)
• Keyin to siz birinchi shakl keladi: You must go. (✗ must to go)
• So‘roq do siz, o‘rin almashtirish bilan: Can you help me? (✗ Do you can)
• Inkor not bilan: cannot/can’t, mustn’t, shouldn’t, might not.
• O‘zining infinitivi va -ing shakli yo‘q, shuning uchun boshqa zamonlarda "o‘rinbosar" ishlatiladi: can → be able to, must → have to.

Asosiy modallar: can, could, may, might, must, shall, should, will, would. Yarim modallar (oddiy fe’l kabi o‘zgaradi): have to, need to, be able to, ought to.

§2. Qobiliyat va ruxsat

Qobiliyat:

• can — hozirgi qobiliyat: I can speak three languages.
• could — o‘tmishdagi umumiy qobiliyat: I could read when I was four.
• was/were able to — o‘tmishdagi muayyan holatda uddalash: The fire was big, but everyone was able to escape. (bu ma’noda ✗ could escape). Inkorda esa couldn’t ham to‘g‘ri: I couldn’t open the door.
• be able to boshqa zamonlarda: I will be able to come. I’ve never been able to swim.

Ruxsat:

• can — oddiy: Can I use your phone?
• could — xushmuomala: Could I ask a question?
• may — rasmiy: May I come in?
• Javobda could ishlatilmaydi: Yes, you can. / Yes, you may.

Misol

The exam was difficult, but I ___ (solve) all the problems.

1. Gap o‘tmishdagi bitta aniq holat haqida (imtihon).
2. Ma’no — qiyin bo‘lsa ham uddaladim.
3. Muayyan holatdagi muvaffaqiyat uchun could emas, was able to.
4. Javob: I was able to solve all the problems.

§3. Majburiyat, taqiq va zarurat yo‘qligi

• must — so‘zlovchining ichki majburiyati yoki yozma qoida: I must call my mother. Passengers must wear seat belts.
• have to — tashqi majburiyat (qoida, sharoit, boshqa odam): I have to wear a uniform at work.
• must ning o‘tmishi yo‘q, o‘tmishda faqat had to: Yesterday I had to work late. Kelajakda — will have to.
• mustn’t — taqiq: You mustn’t smoke here.
• don’t have to / needn’t — zarurat yo‘q (qilsang ham bo‘ladi, qilmasang ham): You don’t have to come — it’s optional.

Bu ikki shakl inkorda butunlay boshqa ma’noga ega, imtihonda tez-tez so‘raladi.

Misol

Tomorrow is Sunday, so I ___ get up early.

1. Yakshanba — ishga yoki o‘qishga borish kerak emas.
2. Erta turish taqiqlanmagan, faqat zarurat yo‘q.
3. Zarurat yo‘qligi → don’t have to.
4. Javob: Tomorrow is Sunday, so I don’t have to get up early.

§4. Maslahat, taklif va tanqid

• should / ought to — maslahat, to‘g‘ri yo‘l: You should see a doctor. You ought to apologise.
• had better + V — kuchli maslahat, aks holda yomon natija: You’d better hurry or you’ll miss the bus. Inkori: You’d better not be late.
• Shall I…? — yordam taklifi: Shall I open the window?; Shall we…? — birga qilishni taklif: Shall we go?
• Could you…? / Would you…? — xushmuomala iltimos: Could you help me?
• O‘tmishdagi afsus yoki tanqid: should have + V3 — qilish kerak edi, lekin qilinmadi: You should have told me. I shouldn’t have eaten so much.

§5. Ehtimollik va mantiqiy xulosa (deduction)

Modal fe’llar dalilga asoslangan xulosani ham bildiradi. Ishonch darajasini eslab qoling:

Hozir haqida (modal + V):

• He’s been working all day — he must be tired.
• She might be at home.
• That can’t be true!

Hozir davom etayotgan jarayon haqida: modal + be + V-ing: She isn’t answering — she must be driving.

O‘tmish haqida (modal + have + V3):

• The street is wet — it must have rained.
• He may have missed the train.
• She can’t have seen me — she didn’t say hello.

Inkor xulosada mustn’t emas, can’t ishlatiladi: ✗ He mustn’t be at home → ✓ He can’t be at home.

Misol

Anvar isn’t answering. He ___ (be) asleep — it’s 2 a.m.

1. Dalil bor: tungi soat 2, telefonga javob yo‘q.
2. Bu kuchli, mantiqiy ijobiy xulosa.
3. Kuchli ijobiy xulosa → must + V.
4. Javob: He must be asleep.

Misol

1. Xulosa o‘tmishdagi harakat haqida (kalitni qachondir qoldirgan).
2. So‘zlovchi aniq bilmaydi — ehtimol.
3. O‘tmish haqida ehtimol: may/might + have + V3.
4. leave ning V3 shakli — left.
5. Javob: I might have left them at school.

§6. Modal fe’lni tanlash algoritmi

1. Ma’no nima: qobiliyat, ruxsat, majburiyat, maslahat yoki xulosa?
2. Zamon qaysi? O‘tmish bo‘lsa: could/was able to, had to, should have, must have.
3. Inkor bo‘lsa, ma’noni tekshiring: taqiq (mustn’t) yoki zarurat yo‘q (don’t have to); inkor xulosa — can’t.
4. Xulosa bo‘lsa, ishonch darajasini baholang: aniq → must, ehtimol → might, mumkin emas → can’t.
5. Modaldan keyin to va -s yo‘qligini tekshiring.
