EI haven't seen him since last week.
EI haven't visited Ali for a week.
EThey have studied English for 7 years. (since)
EThey have studied English since 2000.
نقطة هامة (2) ولكن اذا جاءت طلب استخدام since ولم نستطع تحديد بداية المدة :
He has lived here for five weeks. (since)
الحل في الشكل الآتي :
It is + المدة + since + فاعل + ماضي بسيط
EIt is five weeks since he lived here.
نقطة هامة (3)
اذا طلب استخدام (ago) بدلا من (for) :
فاعل + started/began to + مصدر + المدة + ago.
EHe has worked in this company for 3 years. (ago)
EHe started to work in this company 3 years ago.
نقطة هامة (3)
اذا جاءت التعبيرات الآتية وطلب استخدام (since)

EThe last time I played football was in 2007. (since)
EI haven't played football since 2007.
EShe last visited Aswan when she was young. (since)
EShe hasn't visited Aswan since she was young.


تذكر أن المضارع التام المستمر يعبر عن حدث بدأ وما زال مستمرا ًُو يتكون من :
فاعل + have/has been + v + ing
EHe has been sleeping for 2 hours. ( He is still sleeping)
EThey have been living here since 1999. (They are still living here)
