In a purely biological sense, fear begins with the body’s system for reacting to things that can harm us—the
so-called fight-or-flight response
. "An animal that can’t detect danger can’t stay alive," says Joseph LeDoux. Like animals, humans evolved with an elaborate mechanism for processing information about potential threats. At its core is a cluster of neurons deep in the brain known as the amygdala.
LeDoux studies the way animals and humans respond to threats to understand how we form memories of significant events in our lives. The amygdala receives input from many parts of the brain, including regions responsible for retrieving memories. Using this information, the amygdala appraises a situation—I think this charging dog wants to bite me—and triggers a response by radiating nerve signals throughout the body. These signals produce the familiar signs of distress: trembling, perspiration and fast-moving feet, just to name three.
This fear mechanism is critical to the survival of all animals, but no one can say for sure whether beasts other than humans know they’re afraid. That is, as LeDoux says, "if you put that system into a brain that has consciousness, then you get the feeling of fear."
Humans, says Edward M. Hallowell, have the ability to call up images of bad things that happened in the past and to anticipate future events. Combine these higher thought processes with our hardwired danger-detection systems, and you get a near-universal human phenomenon: worry.
That’s not necessarily a bad thing, says Hallowell. "When used properly, worry is an incredible device ," he says. After all, a little healthy worrying is okay if it leads to constructive action—like having a doctor look at that weird spot on your back.
Hallowell insists, though, that there’ s a right way to worry. "Never do it alone, get the facts and then make a plan." He says. Most of us have survived a recession, so we’re familiar with the belt-tightening strategies needed to survive a slump.
Unfortunately, few of us have much experience dealing with the threat of terrorism, so it’s been difficult to get fact about how we should respond. That’ s why Hallowell believes it was okay for people to indulge some extreme worries last fall by asking doctors for Cipro and buying gas masks.
In Hallowell’ s view, people’ s reaction to the terrorist threat last fall was
选项
A、ridiculous.
B、understandable.
C、over-cautious.
D、sensible.
答案
B
解析
推断题。由题干中last fall定位到最后一段。首句表明因为很少有人有面对恐怖威胁的经 验,所以人们很难得到如何应对这种威胁的信息。最后一句是Hallowell对去年秋天人们面对恐 怖威胁时的表现作出的评论,他认为人们由于极度焦虑所作出的种种行为是正常的,可见 Hallowell对该事件持理解态度,故选B项。
