Someone broke into every flat in the building when all were out. The man in Flat 1 wasn’t home. He was washing his clothes at the laundry ( 洗衣店 ). The woman in Flat 2 wasn’t home either. She was visiting a friend in the hospital. The people in Flat 3 were gone. They were having a picnic at the beach. The man in Flat 4 was out. He was playing tennis in the park. The college students in Flat 5 were away. They were watching a football game. And the elderly lady in Flat 6 was out of town. She was visiting her grandchild.
