how the world works， not always to be determined by it． Moral sensibility is why people will suffer from their beliefs， and why acts of noble self﹣sacrifice are so powerful．

　　　It is admitted that our moral ideals will never be realized completely． But sometimes， however imperfectly， we can make progress． Human dignity requires the love of ideals for their own sake， but nothing requires that the love be returned．

　　　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. 13． 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 al all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. 14． 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. 15．

　　　No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. 16． 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.

　　　17． 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.

三、完形填空

　　　 Last summer， I had just enough money saved to buy a golden ticket﹣a 3﹣month train pass that would take me to the furthest reaches of Europe． Excited for my journey， I 18 all the necessary stuff﹣ 19 the guidebook．

　　　While the 20 of the Internet was definitely a 21 factor to my decision， this was not the only reason I decided to fly 22 ．

To be honest， I find the guidebook 23 a journey﹣like a bossy aunt who is always telling you what to do， 24 she doesn't always know what's best． 25 has taught me that there is a clear 26 between a tourist and a traveler．
