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 tasking. __【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.

_【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. Those are the risks you should jump to take.

B. It all depends on your character.

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.

【3】B

【4】E

【5】G

【解析】

试题分析：文章讲述了对人们冒险的科学研究成果。

【1】F 前面说because when we weigh the risk and the reward，the risk seems worth tasking．（当我们衡量风险和回报时，风险值得去冒）；后面说Some of us enjoy activities that would surprise and scare the rest of us．（有些人喜欢做一些让别人意外和害怕的事。），也就是说衡量风险的标准每个人都可能不一样。故选F。

【2】C 前面说Risk-takers were better at hunting, fighting, or exploring．（喜欢冒险的人更擅长打猎、打仗或探险），这意味着他们有更大的机会生存下去。故选C。

【3】B 前面说So maybe you love car racing，or maybe you hate it.（也许你喜欢赛车，也许你不喜欢。），而这要依赖于你的性格。故选B。

【4】E 前面说scientists say that your willingness to take risks increases during your teenage years．（科学家们指出冒险的意愿在年轻时会增加）；后面说To help you do that, your brain increases your hunger for new experiences．(为了帮你实现那些，大脑会增加你对新的经历的渴望.)，而这些是在你离开家庭，走进一个更大的世界的时候。故选E。

【5】G 空格后面说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．可知，不同的人的大脑在处理快乐和恐惧时表现也会不一样。故前面应该是说大脑的不同反应。故选G。
