My mother makes a lunch box for me every day.

He was paying attention to the teacher's talk during the class.

He broke the glass carelessly.

His carelessness caused the accident.

This issue requires attention.

He was born as an illegitimate child and experienced many difficulties.

My grandfather used to till his privately-owned rice field.

Using the private railway makes commuting very convenient.

We respect Japanese culture.

We are going on a trip tomorrow.
