问题     If you aren’t already paralyzed with stress from reading the financial news, here’s a sure way to achieve that grim state: read a medical-journal article that examines what stress can do to your brain. Stress, you’ll learn, is crippling your neurons. That’s assuming you haven’t already died by then of some other stress-related ailment such as heart disease. As we enter what is sure to be a long period of uncertainty—a gantlet of lost jobs, dwindling assets, home foreclosures and two continuing wars—the downside of stress is certainly worth exploring. But what about the upside? It’s not something we hear much about.
    In the past several years, a lot of us have convinced ourselves that stress is unequivocally negative for everyone, all the time. We’ve blamed stress for a wide variety of problems, from slight memory lapses to full-on dementia—and that’s just in the brain.
    Sure, stress can be bad for you, especially if you react to it with anger or depression or by downing five glasses of Scotch. But what’s often overlooked is a common-sense counterpoint: in some circumstances, it can be good for you, too. As Spencer Rathus puts it in "Psychology: Concepts and Connections," "some stress is healthy and necessary to keep us alert and occupied." "The public has gotten such a uniform message that stress is always harmful," says Janet DiPietro, a developmental psychologist at Johns Hopkins University. "And that’s too bad, because most people do their best under mild to moderate stress."
    The stress response—the body’s hormonal reaction to danger, uncertainty or change—evolved to help us survive, and if we learn how to keep it from overrunning our lives, it still can. In the short term, it can energize us. In the long term, stress can motivate us to do better at jobs we care about. A little of it can prepare us for a lot later on, making us more resilient. Even when it’s extreme, stress may have some positive effects—which is why, in addition to posttraumatic stress disorder, some psychologists are starting to define a phenomenon called posttraumatic growth. "There’s really a biochemical and scientific bias that stress is bad, but anecdotally and clinically, it’s quite evident that it can work for some people," says Orloff. "We need a new wave of research with a more balanced approach to how stress can serve us." Otherwise, we’re all going to spend far more time than we should stressing ourselves out about the fact that we’re stressed out.
Which of the following is not true according to the passage?
选项 A、More should be done to examine the exact way stress affects us.
B、Stress can cause memory loss, even dementia.
C、People may become more adaptable because of stress.
D、The stress response emerged for human’s survival.
答案B
解析 属事实细节题。选项A出现在文章最后一段倒数第二句，Orloff指出我们需要更多的研究来发现压力到底是怎么服务于我们的，故选项A不合题意。选项C是对第四段第_一句的改写，压力让人更具适应性，故不合题意。选项D是对第四段首句的改写，人类之所以有压力反应，就是为了生存，故不合题意。文章第二段讲到人们把很多事都归咎于压力，从轻微的失忆到痴呆，因此这些可能并不真由压力导致，而是人们强加的，故选项B符合题意。
