Help with verbs (past, present modes???)

Hi folks!

I have a terrible problem to understand how to use the following verbs in English:

Past Perfect, Present Perfect, Past Continous, Present Perfect Continous...

The problem is the grammar rule for talk about

- an action that is running and another action stop it;
- an action before another action;
- an action that came from the past to the present (and still happening);
- what's the rule from past that the most important thing is the action, and another rule that the most important thing is the time;
* an action that depends from another action (I don't know if there's a rule about it)*.

I can't express my question very well, if somebody don't understand pleas tell me and I'll try to explain better
In my last vacation I tried to understood it many times, but I can't learn very well in my course. I need desperately a help ><"

Thanks all since now o/
