I felt small but amazed by its power. I think it is amazing because it can sleep for hundreds of years and then erupt. Part 2 The Great Barrier Reef is in danger because of global warming. We can help by reducing pollution and saving energy. For example, we should turn off lights when not using them. Also, we should use fewer plastic products. I believe even small actions can protect the reef. Part 3 Documentaries use bird’s eye view shots because they let us see the full shape of landforms. Without them, we might not understand how big a mountain or a canyon really is. This way, viewers can see how rivers flow or how islands are formed. I think bird’s eye view shots make nature documentaries more exciting and educational. 1 学科网（北京）股份有限公司 $
