双语阅读：只有少数人能坚持运动，科学家的话让我惊呆了
<p>我们都知道运动有好处，我们都知道久坐不动没好处。但为什么我们中的大多数依旧久坐不动呢？这真是个让人不解的悖论。</p><p>说简单点，这都是我们的大脑惹的祸。新的研究发现，懒惰可能是我们在进化过程中发展出的一种生存技能，就和它对于很多其他动物来说一样，所以我们这么喜欢赖在沙发上真的一点也不奇怪。</p><p>"<span word="Conserving">Conserving</span> <span word="energy">energy</span> <span word="has">has</span> <span word="been">been</span> <span word="essential">essential</span> <span word="for">for</span> <span word="humans">humans</span>' <span word="survival">survival</span>, <span word="as">as</span> <span word="it">it</span> <span word="allowed">allowed</span> <span word="us">us</span> <span word="to">to</span> <span word="be">be</span> <span word="more">more</span> <span word="efficient">efficient</span> <span word="in">in</span> <span word="searching">searching</span> <span word="for">for</span> <span word="food">food</span> <span word="and">and</span> <span word="shelter">shelter</span>, <span word="competing">competing</span> <span word="for">for</span> <span word="sexual">sexual</span> <span word="partners">partners</span>, <span word="and">and</span> <span word="avoiding">avoiding</span> <span word="predators">predators</span>," <span word="explains">explains</span> <span word="neuroscientist">neuroscientist</span> <span word="Matthieu">Matthieu</span> <span word="Boisgontier">Boisgontier</span> <span word="from">from</span> <span word="the">the</span> <span word="University">University</span> <span word="of">of</span> <span word="British">British</span> <span word="Columbia">Columbia</span>.</p><p>英属哥伦比亚大学的神经学教授<span word="Matthieu">Matthieu</span> <span word="Boisgontier">Boisgontier</span>说：“保存能量对于人类的生存来讲是至关重要的，因为它让我们在做各种事的时候都更有效率，比如寻找食物和住所、争取性伴侣、躲避掠食者。”</p><p><span word="In">In</span> <span word="a">a</span> <span word="new">new</span> <span word="study">study</span>, <span word="Boisgontier">Boisgontier</span> <span word="and">and</span> <span word="his">his</span> <span word="team">team</span> <span word="tried">tried</span> <span word="to">to</span> <span word="find">find</span> <span word="out">out</span> <span word="just">just</span> <span word="how">how</span> <span word="deeply">deeply</span> <span word="rooted">rooted</span> <span word="laziness">laziness</span> <span word="is">is</span> <span word="in">in</span> <span word="our">our</span> <span word="brains">brains</span>, <span word="by">by</span> <span word="measuring">measuring</span> <span word="our">our</span> <span word="cognitive">cognitive</span> <span word="responses">responses</span> <span word="to">to</span> <span word="different">different</span> <span word="stimuli">stimuli</span> <span word="representing">representing</span> <span word="physical">physical</span> <span word="activity">activity</span> <span word="and">and</span> <span word="sedentary">sedentary</span> <span word="behaviour">behaviour</span>.</p><p>在一项新的研究中，<span word="Boisgontier">Boisgontier</span>的团队测量了我们对多种运动和静止活动的认知反映，以图研究懒惰在我们的大脑中到底扎根多深。</p><p>在其中一项实验中，29名年轻的成年人被要求用电脑进行一项任务，他们可以控制屏幕上的小人儿。屏幕上可能出现多种不同的图像，有的展现出诸如爬楼梯、骑自行车等等的运动行为，有的展现出诸如躺在吊床上这样的静止行为。</p>
