题目

阅读下面短文，理解其大意，然后完成相关小题。     ①Some people like to be scared! Choosing to be scared can be fun. Dr. Margee Kerr, a sociologist, explained the science of fear. "Some people like to be scared because they like the way their body changes." she says.     ②Being scared is not always fun. When a balloon pops, we may jump. Our heart beats faster and harder. How does the body have the reactions?" When we meet something startling, our brain and body start making changes to help prepare us for the unknown." Dr. Kerr explains, "These changes are caused by the senses（感官）, which always send information to the brain. It gives out chemicals into the bloodstream, and those chemicals act on different parts of the body. At the same time, the brain decides whether or not the danger is real."     ③Fear is a tool that the brain uses to keep the body safe. It helps a person to hide, run away, or protect oneself. Our memories also help protect us. As we grow, we learn what's unsafe, and our brains keep those memories. Then our brains use fear to warn us of dangers. Dr.Kerr says, "_______________________________. "     ④However, too much fear can be harmful because experiences can lead to long-lasting fears that may stop a person from trying new things. A long-lasting fear can mean you've had a bad experience, and your brain doesn't want you to have it again.     ⑤Many people have beaten their own fears. Instead of listening to their imagination, they learn the facts about anything that seems scary. Knowledge can help a person feel less afraid. Dr. Kerr grew up on a farm.

She says," After I read a lot about them, I knew for sure what to do if I ever met a bear and how to protect myself." （1） The underlined word "startling" in Paragraph 2 probably means _____________.
