Recently, my tinnitus has been so bad that I decided to see a doctor.

The first time I heard his name was at that party.

His ears are very good, so he can hear distant sounds.

Mr. Shindo is my best friend.

His country was sanctioned by other countries due to nonpayment of tribute.

He presented his research in order to receive the award.

He decided to advance to graduate school after graduating from university.

He is planning to advance to graduate school next year.

We usually represent numbers using the decimal system.

His research has made significant progress.
