Must, have to, don't have to, mustn't

Ingliz tilida «kerak», «shart» ma'nolari bir nechta so'z bilan ifodalanadi. Eng muhim farq: don't have to (shart emas) va mustn't (mumkin emas, taqiq) butunlay boshqa ma'noga ega.

Must va have to: majburiyat

Ikkalasi ham «kerak», «majbur» ma'nosini beradi:

• must — gapiruvchining o'z fikri, ichki majburiyat, qat'iy maslahat: I must call my mother. (o'zim kerak deb hisoblayman) — You must see this film! (qat'iy maslahat)
• have to — tashqi majburiyat: qoida, qonun, jadval, ish: I have to wear a uniform at school. (maktab talab qiladi) — Drivers have to stop at red lights.
