The Science of Risk-Seeking

Sometimes We decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking. 【1】 Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.

The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. 【2】 As the quality of Risk-taking was passed from on ration to the next, humans ended up with a sense of adventure and a tolerance for risk.

So why aren’t we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one Killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. 【3】

No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. 【4】 To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.

Mean taking some risks, so your brain raisers your tolerance for risk as well.

【5】 For the risk-seekers a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.

As experts continue to study the science of risk-seeking, we’ll continue to hit the mountains, the waves or the shallow end of the pool.

A. It all depends on your character.

B. Those are the risks you should jump to take.

C. Being better at those things meant a greater chance of survival.

D. Thus, these well-equipped people survived because they were the fittest.

E. This is when you start to move away from your family and into the bigger world.

F. However, we are not all using the same reference standard to weigh risks and rewards.

G. New brain research suggests our brains work differently when we face a nervous situation.

Answer 1

【答案】

【1】F

【2】C

【3】A

【4】E

【5】G

【解析】

试题分析：文章从科学上对追求冒险和刺激进行了解释。冒险行为与大脑的工作机制有关，当大脑的快乐中枢被激活时，人们就会采取冒险行为。

【1】F考查上下文串联。前一句提到了“weigh the risk and the reward”，F项“然而，并不是所有人都使用同样的参考标准来权衡风险和回报”符合语境，故选F。

【2】C考查上下文串联。hunting, fighting, or exploring狩猎、战斗和探索等活动是生存的必要条件，C项中的those是对这些活动的指代，故选C。

【3】A考查上下文串联。根据“humans developed a range of character types...”可知，人们形成的不同类型的性格如今仍然存在，正是不同的性格类型才导致了我们对冒险行为采取不同的态度，故选A。

【4】E考查上下文串联。E项中的when与“your willingness to take risks increases during your teenage years”中的teenage years对应，故选E。

【5】G考查上下文串联。根据“a part of the brain...while for the rest of us...”可知，本段讲的是冒险行为与大脑的关系，故选G。
