My father has been suffering from sciatica for a long time.

He is working on his job with all his might.

He made the project a success by exerting himself to the utmost.

The Neolithic was an important period in human history.

My friend is suffering from herpes simplex.

I love synthpop music.

We will make this project successful by working together with one mind.

He loves listening to symphonies.

He strongly promoted the southward policy.

He became neurasthenic due to long hours of work.
