conditionals - help needed

can somebody help me with the * verbs? are they correct?
i'm totally lost :-(

life might be easier if everyone in the world *spoke* the same language but i doubt if it *would ever happen*

thank you

Marta,

Your example sentence is correct. I'm not sure if you have a more general question or not. Here is a link that might help with conditionals in more general terms.
