Qoʻllanish holatlari:
1. Mazkur zamon oʻtgan zamonda boshlanib hozirgacha davom etib turgan va gapda ushbu ish-
harakat qancha muddat (qachondan beri) davom etib turganligi koʻrsatilgan ish-harakatlar
uchun qoʻllaniladi. Ish-harakat qancha muddat davom etib turganligi since - dan beri, for - dan
buyon, how long - qachondan beri soʻzlari bilan koʻrsatiladi.

It has been raining since 3 oʻclock. (Soat uchdan beri yomg'ir yog'yapdi)

It has been raining for two hours. (Ikki soatdan buyon yomg'ir yog'yapdi)

How long has it been raining? (Qachondan beri yomg'ir yog'yapdi?)
2. Mazkur zamon oʻtgan zamonda davom etib turgan, lekin hozirga kelib tugallangan va natijasi
ayon boʻlgan ish-harakatlar uchun qoʻllaniladi. Bu yerda ish-harakat qancha davom etganligi
koʻrsatilishi shart emas.

I am tired. I have been working in the garden. (Men charchaganman. Men bog'da
ishlayotgan edim)
Yuqoridagi misolda birinchi gap hozirgi zamondagi natijani (charchaganlikni) va ikkinchi gap
esa charchashga olib kelgan va biroz oldin davom etib turgan ish-harakatni koʻrsatadi.

Tom's hands are dirty. He has been repairing his car. (Tomning qoʻllari kir. U
mashinasini tuzatayotgan edi.)
Yuqoridagi misollarda ish-harakat qancha davom etganligini ham koʻrsatish mumkin, lekin bu
narsa unchalik muhim emas. Bu qoida davomiy ish-harakat natijasida kelib chiqqan natijani
urg'ulash uchun qoʻllaniladi.

I am tired. I have been working in the garden all day.
