My father is a doctor.

Day after day, he continued to strive to solve the problem.

The central processing unit of this computer is very fast.

My father likes to tell dad jokes.

My uncle is a dairy farmer, and he takes care of cows every day.

He is always facing difficulties, just like the proverb 'clouds over the moon, wind in the flowers'.

I am a proud Earthling.

He believes in extraterrestrial life.

The epicentre of the earthquake was right under this city.

This road is under construction, so you cannot pass through.
