In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like "serious illness of a family member" were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stress—it only shows how much you have to deal with. And we now know that the way you handle these events dramatically affects your chances of staying healthy.

By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women’s magazines ran headlines like "Stress causes illness. " If you want to stay physically and mentally healthy, the articles said, avoid stressful events.

But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many—like the death of a loved one—are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription (处方)for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move.

The notion that all stress makes you sick also ignores a lot of what we know about people. It assumes we’re all vulnerable (脆弱的) and passive in the face of adversity (逆境). But what about human initiative and creativity Many come through periods of stress with more physical and mental vigor than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and mental strain.

The result of Holmes-Rahe’s medical research tells us ().

A. the way you handle major events may cause stress

B. what should be done to avoid stress

C. what kind of event would cause stress

D. how to cope with sudden changes in life

传统都有其“原本”,原本是传统的始发言行。传统的始发言行有其特定的原初行动者、特定的受动者,还有其特定的叫作参照系的现实环境。在传统的原本中,所有这些都是特定的、不能代替的。随着时间的推移和历史的进展,原本逐步地被认为是具有权威性的、天经地义的、带有信仰性质的东西而为群体所接受,成为凝聚群体的力量,这样,原本也就逐步地形成为传统。特别值得注意的是,传统逐步形成的过程也是一个逐步远离原本的过程。这里所说的远离,是指原初行动者、受动者和当时的参照系已消失而成为过去。这样,传统在形成过程中就取得了相对独立于原本所处的参照系以及原初说话人、原初受话人的自主性。
下列对“原本”的理解,正确的一项是( )。

A.原本是传统的具有特定原初行动者、受动者、参照系的始发言行
B.原本指权威性的、天经地义的、带有信仰性质的凝聚群体的东西
C.原本是原初行动者、受动者和参照系已消失并成为过去的过程
D.原本指有自主性的相对独立于原初参照系、说话人、受话人的传统
