All landings are different as well as all airplanes.....If you have a high wing trainer type airframe then you can cut throttle on the down wind leg and glide to landing.....try that with a bipe and you'll never make the runway.....
A basic techique is to slow down and descend on the downwind leg...then on the base leg maintain altitude to slow down from the loss of altitude....as you turn final make sure to drop the nose..set up a nice glideslope...use the elevator to maintain speed and your throttle to control altitude......the last of the airspeed will bleed off as you flair to touch down....
I did say that correct by the way, elevator to maintain speed and throttle for altitude....
But like I said all landings are different as well as all airplanes.....you may have to have a click or two of throttle all the way to the runway...depending on the plane and the winds.....
Practice stalls up high so you know how she feels at stall speed....and stay above stall speed on approach....then pratice pratice pratice
