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 one generation 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. 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.

【解析】

試題分析：本文從科學(xué)上對(duì)追求冒險(xiǎn)和刺激進(jìn)行了解釋。冒險(xiǎn)行為與大腦的工作機(jī)制有關(guān)，最喜歡冒險(xiǎn)的時(shí)候發(fā)生在青少年時(shí)期。

【1】F空前句意提到了衡量風(fēng)險(xiǎn)和回報(bào)的標(biāo)準(zhǔn)weigh the risk and reward，選項(xiàng)F“然而，并不是所有人都用同樣的參考標(biāo)準(zhǔn)來(lái)衡量風(fēng)險(xiǎn)和回報(bào)”符合語(yǔ)境，故選F。

【2】C空前句意為“冒險(xiǎn)者在狩獵，打仗和探索方面更擅長(zhǎng)”，選項(xiàng)C“這些方面更擅長(zhǎng)意味著有更大的生存空間”符合語(yǔ)境，而選項(xiàng)C中的“those”指代的是“hunting, fighting and exploring”，故選C。

【3】A空前句意“人們形成的不同類型的性格至今仍然存在，所以，也許你喜歡賽車，也許你討厭它”，選項(xiàng)C“這都取決于你的性格”符合語(yǔ)境，故選A。

【4】E空前句意“科學(xué)家冒險(xiǎn)的意識(shí)是在青少年時(shí)期增長(zhǎng)的”，選項(xiàng)E“這正是你開(kāi)始離開(kāi)家進(jìn)入更大的世界的時(shí)候”符合語(yǔ)境，而選項(xiàng)E中的“when”指代的是“teenage years”，故選E。

【5】G空后句意描述的是面對(duì)危險(xiǎn)的時(shí)候，冒險(xiǎn)者和其他人腦部?jī)煞N不同的感覺(jué)對(duì)比，前者高興，后者害怕，選項(xiàng)G“新的大腦研究表明當(dāng)我們面對(duì)緊張的形勢(shì)時(shí)，我們的大腦運(yùn)轉(zhuǎn)不同”概括本段內(nèi)容，故選G。
