4、次の英文を読み、 設問に答えなさい。 Hello, everyone! Today, I'd like to talk about the Great Barrier Reef, World Heritage Site in Australia. It's the world's largest reef system and consists of over 2,900 reefs. It's longer than Honshu Island. We can see a lot of colorful coral there. Do you know what coral is? It looks like a plant, but it's actually a hard shell formed by animals. The animals are called coral polyps. They lay eggs after the full moon in spring. The Great Barrier Reef is now facing a crisis. More and more coral is turning white. In fact, it's dying because of global warming, water pollution, erosion, and s0 on. This phenomenon is called “coral bleaching." Some scientists say that 80 percent of the Great Barrier Reef will be lost by 2050 if this environmental situation continues. I wonder if future generations will be able to see these beautiful reefs decades from now. There are a lot of coral reefs around the world. It's very important to protect these precious coral reefs. How can we do this? Well, to prevent global warming, we should save energy such as electricity and reduce the amount of carbon dioxide in the atmosphere. There are many small things we can do at school and home. I believe that our small actions will make a big difference in the end. Thank you for listening.

One good theory is that around the same time many women, especially ( 4 ) who were wealthy or noble, did not dress themselves. A servant did that for them. As the servants were also mostly right-handed, it made sense for women's buttons to be on the left. And as fashion is often determined by the rich and famous before 25 being copied by the rest of us, it is thought that the pattern for all women was set in that way.
