He has many Greek friends.

I am thinking of learning Greek.

He is quite a good cook.

I think his Japanese has improved quite a bit, hasn't it?

My keys are inside the house.

He is an expert in mythology and gave a lecture on the gods of ancient Greece.

His position was in name but not in reality.

The Tale of Genji is the oldest story in Japan, written by Murasaki Shikibu.

This is my first question.
