A certain person is my best friend.

His hair is black and long.

In an old poem, the beauty of the dragonfly is praised.

He is famous for his violent behavior.

He spoke rudely to me.

He viewed the beautiful sea from the window.

The view from this room is wonderful.

This area is constructing a new dam for flood prevention.

We should do our best to defend our country.

The death of this civilization is inevitable.
