can someone explain me.. we can't do road if there a settlement or city ?

You can't build past an opponent's settlement or city. This is a very common question. The Catan rulebook pdf is online for free with many examples. Read it.

I think part of the confusion is that you can build a settlement in between an opponent's 2 roads but you can't build a road through an opponent's settlement.
