Read the stories and complete the tasks.AImagine that you're sitting in your dark living room watching a scary movie. The main character hears a noise in the basement. She decides to go down to see what it is. As a viewer, you know that there's a monster in the basement and the main character shouldn't go downstairs. You also know that at some point soon, the monster is going to jump out at the main character. Still, even though you're expecting it, you jump. What does your face look like at this moment? If you were genuinely scared, your eyes would be wide and your mouth open. Why does this happen? Scientist Charles Darwin had an explanation. He found that when we are scared, we instinctively tighten our muscles, even the muscles in our face. This is so we are ready to defend ourselves or run away if we have to. When we are truly scared, we can't avoid tightening these muscles, and inevitably, we make the face of fear. BWhen you feel scared, whether it's for a moment when someone jumps out at you from behind a door, or for several minutes while you wonder if the noise you hear outside is a burglar or just your neighbour's cat, your body changes in certain ways. Some of these changes are noticeable. Your heart beats faster, your breathing rate increases, and your face might become flushed or get very pale. Other changes are not visible. Your blood vessels become wider, your digestion slows down or might even stop, and your hearing and vision become very focused. All of these changes are part of your fight or flight response to fear, and they help you fight off an attacker or get away as fast as you can. For example, wider blood vessels allow more blood to get to your muscles so they are stronger. Your digestion slows down because your body needs all its energy to deal with the current threat. And your hearing and vision Change so you can locate a threat more easily.Look at the headlines. Match each headline to the correct topic.
