King Juan Carlos of Spain once insisted “kings don’t give up the throne(王位), they die in their sleep.” But embarrassing scandals and the popularity of the republican left in the recent Euro-elections have forced him to eat his words and stand down. So does the Spanish crisis suggest that monarchy(君主制) is seeing its last days? Does that mean the writing is on the wall for all European royals, with their magnificent uniforms and majestic lifestyles?

The Spanish case provides arguments both for and against monarchy. When public opinion is particularly polarized, as it was following the end of the Franco regime, monarchs can rise above mere politics and symbolize a spirit of national unity.

It is this apparent transcendence(超越) of politics that explains monarchs continuing popularity as heads of state. And so, the Middle East excepted, Europe is the most monarch- filled region in the world, with 10 kingdoms (not counting Vatican City and Andorra). Most royal families have survived because they allow voters to avoid the difficult search for a non-controversial but respected public figure.

Even so, kings and queens undoubtedly have a downside. Symbolic of national unity as they claim to be, their very history and sometimes the way they behave today symbolizes outdated and indefensible privileges and inequalities. At a time when Thomas Piketty and other economists are warning of rising inequality and the increasing power of inherited wealth, it is strange that wealthy noble families should still be the symbolic heart of modern democratic(民主的)states.

The most successful monarchies try their best to abandon or hide their old noble ways. Princes and princesses have day-jobs and ride bicycles, not horses (or helicopters). Even so, these are wealthy families who party with the international 1%, and media interference makes it increasingly difficult to maintain the right image.

Now scientists have discovered the first evidence that the animals actually behave like their masters. Just like children, they adopt a “look and learn” approach which means they can mimic (模仿) human's actions when going about their tasks.

Biologists and psychologists at the universities of Vienna and Oxford designed an experiment to test the theory that dogs do have the ability to copy what they see, using a simple wooden box. In the study, ten owners showed their dogs how to open the wooden box, sometimes using their heads to push a handle and sometimes using their hands.

In the first part of the test, five dogs were rewarded with a piece of sausage for copying their owners' actions. The other five were rewarded with food for not copying, and using other methods. With each dog the experiment was repeated hundreds of times, and the time taken for a dog to get it “right” on 85 percent of attempts (17 goes out of 20) was recorded. The dogs encouraged to mirror their owners reached this point almost three times sooner on average than those rewarded for not copying them. In the second part of the test, all the dogs were only rewarded for copying the method their owners used. The five dogs previously rewarded for copying their owners reached the 85 percent mark more than twice as the other five.

In a paper published in Proceeding of the Royal Society, they concluded, “Like humans, dogs can't help imitating actions they see.” Going further, they said, “The results suggest the imitative (模仿的) behavior of dogs is shaped more by their developmental interactions with humans than by their evolutionary (进化的) history of domestication (驯化).”

Caroline Kisko, from the Kennel club, said, “A dog's behavior is influenced much like that of a child learning right from wrong and adopting similar patterns of behavior. We hope that owners understand the importance of their actions and use this knowledge to set good examples and therefore positively influence the behavior of their pets.”

Scientists have exactly discovered the set of brain cells involved in making risky decisions, and have been able to control them in rats using targeted light. By changing the activity of the cells they were able to change the behaviour of risk-taking rats to avoid risk, hinting the approach could in future be used to treat people with impulse (冲动) control problems.

Risk-taking is a key part of survival, knowing when to take a chance could pay off—such as moving to a new area to look for food when pickings are slim.

While all animals need an element of risk, the preference towards it varies between individuals. Researchers found this variation, which determines how risk-averse an individual is, is regulated by brain cells in a region of the brain called the nucleus accumbens. This cluster of neurons releases the neurotransmitter dopamine, which regulates the brain’s reward and pleasure centres.

Previous studies have shown that in patients with Parkinson’s disease, taking medication which blocks specific dopamine receptors (DR2) (受体) leads to increased gambling (赌博) behaviour and risk taking behaviour. In studies with rats, researchers were able to use a technique called optogenetics (光遗传学)—which uses light sensitive proteins to change the activity of cells—to modify cells with DR2 in the nucleus accumbens.

Rats were trained to choose one of two levers, offering them a choice between a “safe” or “risky” choice. The safe option resulted in a small, but consistent amount of a sugar water treat. But the risky choice consistently delivered smaller amounts of sugar water, with the occasional large pay off—essentially encouraging the animals to gamble for a bigger prize. Around two-thirds of the animals weren’t keen on risk, opting for the safe option, but the remaining third were risk-seekers. Brain scans of the animals showed that those with low levels of DR2 consistently went for the gamble.

But using pulses of light to stimulate (刺激) the DR2 cells and improve their activity could cause the risk-takers to play it safe and opt for the guaranteed but less rewarding option. Once the light-pulses stopped, the risk-takers returned to their gambling strategy.

In the risk-averse animals, stimulating the same cells had little to no effect.

Professor Karl Deisseroth, of Stanford University in California, said: “Humans and rats have similar brain structures involved.”And we found a drug known to increase risk preference in people had the same effect on the rats. So every indication is that these findings are relevant to humans. “Risky behavior has its moments where it’ s valuable. As a species, we wouldn’t have come as far as we have without it.”

1.The variation in people’s preference towards risks is directly regulated by ________.

A. nucleus accumbens B. light sensitive proteins

C. neurons D. dopamine

2.From the experiment with rats, we can conclude that ________.

A. the lack of DR2 cells results in a safe option

B. the levels of DR2 have little to do with their choices

C. the high levels of DR2 can make animals avoid risks

3.The underlined words in Paragraph 7 most likely mean the animals that are ________.

A. willing to take big risks

B. reluctant to take risks

C. fond of gambling strategy

D. afraid of receiving stimulation

4.What can be inferred from what Professor Karl Deisseroth said?

A. Humans and rats differ in their preference for risk-taking.

B. Too much risk-taking can do more harm than good.

C. Risk-taking can be used to treat people with impulse control problems.

D. Risk-taking is a means of survival and brings higher returns to humans.

While going through life with the pursuit of money on our mind, we're often told that money can't buy happiness. But what truth is there in the saying? Is there a relation between money and happiness? 1.

Humans are very sensitive to change. When we get a rise, we really enjoy it. But some studies have shown that in North America, additional income beyond 75,000 dollars a year stops impacting day-to-day happiness. 2. They often end up spending all the money, going into debt, and experience ruined social relationships.

So surely money can't really buy happiness. Well, recent studies suggest that the problem may actually be in the way that we spend money. 3. Studies show that people who spend their money on others feel happier. As for the people who spend money on themselves, their happiness is unchanged.

4. 0ne experiment showed that instead of an organization writing a large check to a charity, dividing the amount up among employees, allowing them to contribute to a charity of their choice, increased their job satisfaction. Similarly, individuals that spend money on each other, as opposed to themselves, not only increase job satisfaction, but improve the team performance.

5. Interestingly, the specific way money is spent on others isn't important. Spending something on others is the important aspect of increasing your happiness.

A. The same principle has been tested on teams and organizations as well.

B. Money has more effect on the vast majority of people in the long run.

C. Instead of buying things for yourself, try giving some of it to other people and see how you feel.

D. And if so, how can we use it to our advantage?

E. Almost everywhere we look in the world, we see that giving money to others is positively related to happiness,

F. And while you're saving up for these greatest experiences, don't forget the daily joys in life.

G. In fact, people who win a lottery often report becoming extremely unhappy.
