1．快速浏览全文，把握文章脉络
文中阴影部分皆为具体阐释或举例，所以无需仔细阅读，可快速浏览甚至跳过不看。而下划线部分的成分则需读者特别注意，如第三段的this，它表明该段是上文的总结；that is表明后文为前文的解释，所以读者如果前文看懂了，后文也就没有太大作用了。
Passage OneIn 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 (神经元) deep in the brain known as the amygdala (扁桃核).
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 facts 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 (抗炭疽菌的药物) and buying gas masks.
2．仔细研析题干，确定关键词语选择题的解答成功与否，主要取决于对题干的充分挖掘。如第53题，该题定位并不难，因为人名是最为容易确定的线索，再加上study一词便可确定答案所在地。但该题的关键在于learn一词，它决定了正确答案肯定不是原文直接言明，而是间接暗示的，所以由此可先排除文章直接言明的选项B)和C)。选项A)与所在段的内容不相干，所以正确答案为D)。
53. From the studies conducted by LeDoux we learn that _________.
A) reactions of humans and animals to dangerous situations are often unpredictable
B) memories of significant events enable people to control fear and distress
C) people's unpleasant memories are derived from their feelings of fear
D) the amygdala plays a vital part in human and animals responses to potential danger
