2. Agar if qatnashgan gaplarda should, had yoki were fe'llari qatnashsa, gap boshida kelgan if
bog'lovchisini tushirib qoldirishimiz mumkin. Bunday hollarda should, had va were koʻmakchi fe'llaridan
biri egadan oldinga chiqadi, ya'ni inversiya holati yuz beradi. Bu holat asosan rasmiy va adabiy ingliz tilida
uchraydi.

3. If it hadn't been/was/were not for + ot qurilmasi asosiy gapdagi holat biror-bir vaziyatga yoki shaxsga
bog'liq boʻlganda qoʻllaniladi.

boʻlmaganida, men hech qachon universitetga kirolmagan boʻlardim.)

parents... shaklida ham qoʻllashimiz mumkin.
