My acne has been getting worse recently.

Don't you think his behavior has been strange lately?

Nowadays, he goes to the gym every day.

My lymph glands are swollen, so I need to see a doctor.

He had a sore on his face.

I thought his behavior was really cruel.

Aldehyde is a very important compound in organic chemistry.

I think his behavior is unjust.

I think his actions are completely inhumane.

It seems like he has been poisoned by something.
