When you are on final, lined up and have the proper attitude, use your throttle to control your approach. If you are sinking too fast, and will likely end up short, add power.
The idea is not to adjust your pitch once you are setup for a final approach - only use your throttle. In other a/c you can play with flaps etc...
Just because you can land other aircraft, doesn't mean you are landing correctly.
Take this for example:
The mechanics apply, except at the end, as renhanxue said, arm your throttle reverse, and then slam it into the ground - no need to flare and hold (otherwise, you will likely fly past the runway if you are using one of the short ones).

Approach speed
Approach Attitude
Don't play too much with the stick - find an attitude, and trim to it. Do not let your plane approach stalling speed. If you stall on final, you die.
Different airplane, similar mechanics to most fixed wing a/c.
Hope that helps.
