He sings. He is a singer.
She extinguishes the fire. She is a firefighter.
He travels to the space in a rocket.
It is an elephant.
He prepares bread. He is a baker.
She drives a taxi. She is a taxi driver.
She writes books.
She keeps and works the library. She is a librarian.
It lives and swims in the sea. It is a dolphin.
She teaches in a school.
