choose :

Noha is going on holiday . I'm sure she (has.will have . is having . is going to have )

ايه يا جماااعة مفيش حد جااوب لييه؟

choose what you like and tell me when you have made your choice
لأن choice بييجي معاها make مش do

Give me one good reason why i should help you
cause = reason
cause of + noun/ gerund = reason for + noun/ gerund = reason why + clause
بمعنى لو انا عايزة اكتب السبب وقبله why يبقى هختار reason why لأن مافيش حاجة اسمها cause why

My school starts a new project about using technology of learning

I've decided to expand my company , so i am going to employ more staff
الافعال decide, intend, plan لازمآخد معاهم am/ is / are + going to + inf

I'll bring the post to you in your office when it will arrive
الصراحة مش متأكدة من دي بس هقول when it arrives

Noha is going on holiday I'm sure she ( has - will have - is having - is going to have ) fun.
انا كتبت fun لأن الجملة ناقصة حاجة have ايه ؟ اكيد have fun - have a great time حاجات زي دي. :)
