The night is quiet and beautiful.

His work is full of vigour.

The study of artificial life is a new frontier in science.

His body is very healthy.

He made three robots.

He exercises his body every day.

His body looks like that of an athlete.

I will attend my friend's birthday party on the fourteenth.

I am planning to have my birthday party on the twenty-fourth.

He has a strength that is not apparent.
