During the polar night, the sun does not rise even once.

Gaia is the goddess of the earth in Greek mythology.

He rode the horse like a knight.

He is leading ten horsemen.

He rode through the forest on a horse.

He rode a horse and strolled around the town.

As dawn broke, I could hear the birds singing.

There are three post offices in my town.

This tune is my favorite.

I mailed a letter at the post office.
