Your English is horrible.
The load is not connected across the drain. The load is connected between the drain and the positive supply voltage. Then when the gate is positive 10V to 12V then the drain goes to ground and the load gets the full 12V supply voltage.
There are thousands of "ordinary" Mosfets that need a Vgs of 10V to completely turn on.
There are a few hundred "logic-level" Mosfets that need a Vgs of 4.5V to 5V to completely turn on.
There are only a few unusual Mosfets that need a Vgs of only 2V to completely turn on.
