Hello everybody:
I hope that you are all alright 
Well, today I want to give the difference between the use of can and could. Ofcourse we know all that *could* is the past of *can*
,
We use can :
**General ability ( in the present)
- I can speak English.
**Asking for permission:
-Can I borrow your pan please?
**To request something:
-Can you help me please?.
**Possibility:
- I can get very cold there at night.
**An offer to help someone
-Can I carry your bag for you?
**Cannot (can't)=not allowed to
- You cannot smoke in this room
-You can't go to the party..
