اعتقد ممكن تكون had been left on
لانه الحدث الاول من حدثين حدثوا في المااضي

تكون had لانة تعبر عن حدث اول ومحدش يفكر ان الخطأ في arrived وتكون arrived at طب لية لان home ما يجيش قبلها حرف جر هنا



مع تحياتي بالتوفيق

had in stead of have

When we had arrived home, we saw that our lights have turned on
لأن وصلنا أولاً ثم رأينا وturned on
و ليس left on

When I arrived home, we saw that our lights had been left on

had been left
اذا كان هناك اكثر من حدث فى زمن الماضى فى جملة واحدة فاننا نضع اقدم هذه الاحداث فى الماضى التام وباقى الاحداث تكون فى الماضى البسيط.
مع تمنياتى لك بالتفوق.

had been left

had been left o n

had بدل من have

شكرا جزيلا لكم
