Past Simple:

She walked to school every day. He bought a new car last week. They visited their grandparents over the weekend. I finished my homework before dinner. The cat caught a mouse in the garden. We watched a movie together last night. The sun set behind the mountains.

Past Progressive:

She was studying for her exam all night!The children were playing in the park when it started raining.I was cooking dinner while listening to music.The birds were chirping happily in the trees.They were dancing at the party when the music suddenly stopped.We were walking along the beach when we found a message in a bottle.The flowers were blooming beautifully in the springtime.
