Wow!!! 
"dirk85" and "galaxy flyer" thank you to both, for your kind and fast answers.
I'm learning as much as possible from the two answers.
First of all say that, after "losing" 15 minutes trying to identify the different airspaces I appreciated
one significative topic:
--->In the US Charts the "system" used to mark the airspaces are completely different to the system used f.e. in Europe and in a lot of countries of South America.....<----
I think that "dirk85" have the reason.... for the route FXE to BCT there is not class B airspace; for me that seems
"C". And if you" follow" (more or less) the motorway I-95 (remember that we are in VFR and navigating visually ... And that road is a very good reference
) abeam Pompano Beach airport could be active (or not depends about the time as it's reflected on the chart....) a Class D airspace ¿Are someone agree with me?
Just one question in Florida the ATC give you "BLOCK ALTITUDES" for VFR flight instead block+500 feets?
