Look at these comparisons:
Plus je regarde la télévision, plus je la déteste
The more I watch television, the more I hate it.
Plus tu es beau, plus la vie est facile.
The more beautiful you are, the easier life is
Moins je dors, moins j'en ai besoin
The less I sleep, the less I need to
Plus j'écoute, moins je l'aime
The more I listen, the less I like it
Notice that expressions like the more X the more Y are similar in French, but the definite article (the) doesn't make an appearance.
Note also that in French you keep the order of the sentence intact, unlike English where you put the adjective after more for example, The more anxious you are...
Plus nous sommes généreux, plus les gens nous le rendront.
The more generous we are, the more people will give it back to us.

Bonjour Tamara !
The sound example was actually wrong, and thanks to you, it's now been fixed! In the expression "plus...plus...", you don't pronounce the 's' at the end of 'plus'.
Here is the fixed lesson:

Bonjour Aaron,
The general rule is that s at the end of the French word plus is pronounced when it's positive, and not when it's negative. So,
J'ai plus de temps = I have more time = s is pronounced.
Je n'ai plus de temps = I don't have any more time = s is silent.

However, I'm afraid that perhaps I wasn't specific enough — I didn't realize my question would be posted on a separate page without the full context of the exercise that gave rise to it.
My question was concerning the *plus [clause] plus [clause]* construction, which I did think might fall under the general rule, but since I posted it, I've read conflicting answers elsewhere. Some suggest that the *s* is not pronounced in this context, and some say that in this context both ways of saying *plus* are heard.

Rebonjour Aaron,
Sorry about that. In certain expressions, including plus __ plus ___ and de plus en plus, pronouncing the s at the end of the plus is optional. (Unless of course there's a required liaison, as in de plus en plus.)

How then do you use "le plus" or "le moins"
