I am currently typing on my computer.She is dancing to her favorite song.They are playing basketball in the park.He is studying for his math exam.We are eating lunch together.The dog is barking at the mailman.The baby is sleeping in her crib.The chef is cooking a delicious meal.The birds are chirping outside my window.The construction workers are building a new skyscraper.The students are taking notes during the lecture.The singer is performing on stage.The mechanic is fixing a car engine.The artist is painting a beautiful portrait.The swimmer is practicing her strokes in the pool.
