He sang a song while playing the floor drum.

He suddenly stood up and left the room.

After all, he is my best friend.

He was diagnosed with lung cancer.

He is a famous haiku poet.

His heart was surging like water.

Looking at the sea where the waves were surging, he was moved.

The blastula stage is a very important phase in the process of biological development.

It is his habit to worship at the shrine every day.

He suffered for a long time from a lung disease.
