Question

【題目】While I will explain a bit about the science of stress and relaxation a little later simple way to think about it is that our body 's stress response works like a car alarm. Keep us safe by warning us of the presence of danger in our immediate environment.

But instead of warning us with a loud and annoying sound，our body alarm system lets us know that something is wrong by creating changes in our neurochemistry (神經(jīng)化學(xué)）.If you've ever experienced pain in your stomach，periods of extreme anger, inability to focus or even insomnia (失眠），chances are your body was paying the price in those moments for the brain chemistry of stress.

So if it's so uncomfortable，why not just get rid of stress altogether?

This is not only impractical，it would be dangerous. Let's go back to the metaphor (比喻說法）of the car alarm. If the alarm is turned off altogether，the car is exposed to continual danger without there being any way of your knowing about it until it is too late. It would be like walking through the jungle without any fear signal in the presence of a poisonous snake or other dangerous animals — while it might feel “nice” to be so relaxed，your body actually needs the stress response not only to remind you of danger but also to offer extra adrenaline (腎上腺素) for your heart and extra blood and oxygen for your arms and legs.

However，if the car alarm goes off at any time，someone just looks at the car with a bit of an attitude，and it becomes equally useless. Not only do we stop paying attention to it，but it begins to drive us and everyone around us becomes a little bit crazy. In the case of our bodies，walking around in a constant state of alarm also has some pretty alarming health consequences，which we will explore in greater depth in the next chapter.

【4】D

【解析】

試題分析：文章用比喻的方法,把人類身體比作車,人類身體勞累也會象車一樣報警。

【1】B 細(xì)節(jié)理解題。在文章中的第一段Keep us safe by warning us of the presence of danger in our immediate environment.通過提醒預(yù)警,提醒我們危險的出現(xiàn)。由此句可知，兩者的共同點在于，給出預(yù)警信號,因此選B。

【2】 C 推理判斷題。根據(jù)文章第二段最后一句If you've ever experienced pain in your stomach，periods of extreme anger, inability to focus or even insomnia (失眠），chances are your body was paying the price in those moments for the brain chemistry of stress.如果你感覺到胃部疼痛，一段時期的極其憤怒，難以集中注意力，或者失眠，那么你的身體就是在為大腦化學(xué)的壓力付出代價。由此句可知，身體報警系統(tǒng)工作時，身體是有變化的，如胃部疼痛，極其憤怒， 失眠等。因此C 為正確選項。

【3】 D 細(xì)節(jié)理解題。從第四段 If the alarm is turned off altogether，the car is exposed to continual danger without there being any way of your knowing about it until it is too late. 可知,如果發(fā)動機的報警系統(tǒng)被關(guān)掉,車輛就完全暴露在不斷的危險中,而沒有任何跡象讓你知道, 直到太晚。 也就是D 選項的說法，我們不能意識到可能存在的危險。

【4】 D 推理判斷題。文章第四段末while it might feel “nice” to be so relaxed, your body actually needs the stress response not only to remind you of danger but also to offer extra adrenaline for your heart and extra blood and oxygen for your arms and legs.句意,就象放松的時候感覺很好一樣,你的身體真的需要壓力反應(yīng),不僅為為了提醒你危險的存在, 也是為了給你的心臟提供腎上腺,為你的胳膊,腿提供額外的血液和氧氣。由此可知，如果完全失去壓力， 我們就不能意識到潛在危險的存在，就象人走在叢林中而不知毒蛇,猛獸的存在,這樣 很容易引起讀者共鳴, 以此來說明壓力反映存在的必要性, 所以選D。
