The roof of this house is made of thatch.

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 from a commoner background and succeeded by working hard.

His heart is vague and dark.

He was watching the enemy's movements from the watchtower.

He finally accomplished the project.
