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. 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, orexploring. 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 youlove car racing, or maybe you hate it.
No matter where you are on the risk-seeking range,scientists say that your willingness to take risks increases during your teenage years. Tohelp 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.
For the risk-seekers a partof 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 continueto 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 shouldjump to take.
C. Being better at those thingsmeant a greater chance of survival.
D. Thus, these well-equipped people survived becausethey were the fittest.
E. This is when you start to move away from your family and into thebigger world.
F. However, we are not all using the same reference standard to weighrisks and rewards.
G. New brain research suggests our brains work differently when weface a nervous situation.

Answer 1

【答案】F；C；A；E；G
【解析】文章從科學(xué)上追求冒險(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)，當(dāng)大腦的快樂中樞被激活時(shí)，人們就會采取冒險(xiǎn)行為。
①考查上下文串聯(lián)。前一句提到了“weigh the riskand the reward”，F(xiàn)項(xiàng)“然而，并不是所有人都是用同樣的參考標(biāo)準(zhǔn)來權(quán)衡風(fēng)險(xiǎn)和回報(bào)”符合語境，故選F。
②考查上下文串聯(lián)。Hunting，fighting，orexploring狩獵、戰(zhàn)斗和探索等活動(dòng)是生存的必要條件，C項(xiàng)中的these是對這些活動(dòng)的指代，故選C。
③考查上下文串聯(lián)。根據(jù)“human developeda range of character types……”可知，人們形成的不同類型的性格如今仍然存在，正是不同的性格類型才導(dǎo)致了我我們對冒險(xiǎn)行為采取不同的態(tài)度，故選A。
④考查上下文串聯(lián)。E項(xiàng)中的when與“yourwillingness to take risks increases during your teenage years”中的teenageyears對應(yīng)，故選E。
⑤考查上下文串聯(lián)。根據(jù)“a part of thebrain…white for the rest of us…”可知，本段講的是冒險(xiǎn)行為與大腦的關(guān)系，故選G。
