They were playing basketball when it started to rain.She was studying for her exam all night last night.The dog was barking loudly while the thunderstorm was raging outside.I was watching a movie when my phone suddenly rang.The children were laughing and playing in the park when their parents arrived.He was reading a book when the power went out.We were driving to the beach when we got a flat tire.The students were taking a test when the fire alarm went off.The singer was performing on stage when the audience cheered loudly.It was snowing heavily while they were skiing in the mountains.
