Ready to Scream?

Fear can be fun. Many young people queue up to ride very fast and scary(吓人的)roller coasters, screaming but enjoying themselves. Other people like to read "goose bumps"(鸡皮疙瘩)books or watch horror movies(恐怖电影)at night, scared to death but feeling excited._____(46)

Fear is an ancient way of surviving. Being scared makes animals (including humans) flee (逃走) from danger and save themselves. It is because of fear that we have lived through millions of years of evolution. Those who lacked a strong fear response (反应) were more likely to be killed,_____(47)

What happens in the brain when something frightens you?

Nerves (神经) that begin at the eyes and ears lead to a part of the brain called the amygdala (类扁桃体). When you suddenly see a snake, for example, the amygdala makes you freeze, perspire (流汗), have a quickened heartbeat, or run very fast.

However, seeing the snake also uses another part of the brain, the cortex (皮层). It analyzes (分析) the situation, and if it finds that the snake is only made of rubber it tells your heart and the rest of your body to calm down. _____(48)

Back to the first question: Why do some people like to make themselves scared?

One reason is that we can play games with fear,_____(49)Kalin said: "To believe we have control over a situation gives us a feeling of power."

"Scary movies or novels are good practice to prepare young people for the real thing. _____(50).
