The faster...the earlier
That's a kind of construction I don't understand jet.
For example:
-The faster you drive the earlier you get there.
- The more you study the better your English ( is)
- the more the friends ( you have ) the better.

Some time you insert the verb in the first and second part of the frase but other times you don't.
Really I can't understand .
Could you help me ?
