我很开心的花样表达

I’m on Cloud Nine.

I’m in seventh heaven.

I’m walking on air.

I’m on top of the world.

I’m sitting on top of the world.

I’m high on life.

I’m feeling good.

I’m feeling fine.

I’m as merry as the day is long.

I’m happy as can be.

I’m happy as a clam.

I’m as happy as a clam.

I’m as pleased as punch.

I’m beside myself with joy.

I couldn’t be happier.
