Q1: 'The Ocean Explorer' - Read the passage aloud

Marine biologists spend their lives studying the mysteries of the sea. One such explorer, Dr. Lin, travels to deep ocean trenches to observe rare creatures. Her team uses submersibles equipped with cameras and sensors to record data. In one expedition, they discovered a jellyfish that glowed in complete darkness. 'It’s like finding a star underwater,' Dr. Lin said. The ocean covers more than 70% of Earth, yet much of it remains unexplored. Scientists believe there are thousands of species still unknown. By studying the ocean, we learn about climate, ecosystems, and even medicine. Dr. Lin hopes her work will inspire others to protect marine life and continue exploring the deep.
