I took a course to learn Japanese.

I read this weekly magazine every week.

He was behaving as a model prisoner in the prison.

He is specially studying mathematics.

He is doing a specialized study in economics.

I found a Japanese clover flower in the park.

He claims to be a victim of gangstalking.

I am on weekly duty this week.

We crossed the river by crossing the pontoon bridge.

We should respect the ancient customs of that region.
