Mr. Doi is my best friend.

He was bitten by a venomous snake.

A construction worker is working at the construction site.

The hermit crab, known as 'yadokari' in Japanese, got its name from its habit of borrowing the shells of other creatures to live in.

Mr. Kadokawa is my Japanese teacher.

He started his own independent business.

He proposed an original idea.

When I'm near him, I feel like I can hear my heart beating.

His heart throbbed throbbingly.

He slammed the door shut.
