Shall I close the door?
Shall I come out?
Shall I visit my friend?

I am going to visit my boyfriend tomorrow
I am going to have a dog
I am going to go shopping on Friday

I will remember it whole my life
I will be a doctor
I will be a good boy

(Shall, will)
Kate will cook dinner tomorrow. Will you go to the south next summer? What will your brother do tomorrow?
(will be)
There will be one of the most beautiful fountains in the world here. He will be one of the best pupils in his class if he studies well. The man will be tired if he works hardly.
(to be going to)
I'm going to fly away tomorrow. He's going to tell her something. The women are going to prevent them from the unpleasant event.
