they break because they're cheap spokes, and i'm assuming you have the stock sprocket set up with the rag joint, right? the torsion applied to the wheel from being driven off the spokes will tweak both sides, a push pull effect.

also, most new bikes don't have the spokes properly tensioned, and they'll loosen up.

upgrading to a sprocket adapter that runs off the hub and a wheel with 12gauge spokes will solve all your problems.

check out bikepartsusa.com. i think they have cheap, heavy duty wheels for mountain bikes.

and creative engineering or pirate cycles for the adapter.

If you want the smaller spokes to last, Don't overtighten the rag joint.
Also, once you install the rag joint, re-check all the spokes for proper tension and make sure your wheel is true.
