Yoshihiko is my best friend.

He has abandoned his own personal gain and is working for the public good.

The moon on the sixteenth night is beautiful, isn't it?

He stays well because he leads a healthy lifestyle.

The sound of the night rain hits the window glass.

He is an ambitious student, always wanting to learn new things.

He started a life of abstinence for his health.

He decided to be abstinent for his health.

He was able to grasp the gist of the story quickly.

He got car sick from the long drive.
