I had seen pictures of it before, but nothing could prepare me for the real experience. The moment I saw the turquoise water and the colourful corals, I knew this would be an unforgettable journey. We took a boat from Cairns to the outer reef. The ride took about two hours. When we arrived, we put on our snorkelling gear and jumped into the water. It was like entering a different world. There were fish of every colour swimming around us. I saw a large sea turtle slowly swimming past. It was so close that I could almost touch it. The guide told us that the reef was home to over 1,500 species of fish and 400 species of corals. I was amazed by the incredible biodiversity. We also went on a glass-bottom boat tour, which allowed us to see the reef without getting wet. On the last day, we took a helicopter ride over the reef. From the air, the view was breathtaking. The reef stretched out as far as I could see, with different shades of blue and green. I took hundreds of photos to remember the experience. I will never forget this trip. It opened my eyes to the beauty of nature and reminded me of the importance of protecting our oceans. ( )6. Where did the writer take a boat from? A. Sydney. B. Cairns. C. Melbourne. D. Brisbane.

Scientists have discovered over 600 species of corals and more than 2,000 species of fish in this area. The Coral Triangle is also home to six species of sea turtles and many types of whales and dolphins. However, this rich ecosystem is in great danger. Overfishing and pollution are causing serious damage. Climate change is also warming the ocean, which harms the corals. Many marine animals are losing their homes. Conservation groups are working hard to protect the Coral Triangle. They are creating protected areas and working with local communities to promote sustainable fishing practices.
