History has witnessed the endless productions of Shakespearean plays in every major language of the world. It is never rare to find that Mozart packs Japanese concert halls, as Japanese painter Hiroshige does Paris galleries, Unique works of this kind are different from today's popular art, even if they began as works of popular art. They have set themselves apart in their timeless appeal and will probably be enjoyed for centuries into the future.

               In a 1757 essay, the philosopher David Hume argued that because“the general principles of taste are uniform(不变的) in human nature,”the value of some works of art might be essentially permanent. He observed that Homer was still admired after two thousand years. Works of this type, he believed, spoke to deep and unvarying features of human nature and could continue to exist over centuries.

               Now researchers are applying scientific methods to the study of the universality of art. For example, evolutionary psychology is being used by literary scholars to explain the long-lasting themes and plot devices in fiction. The structures of musical pieces are now open to experimental analysis as never before. Research findings seem to indicate that the creation by a great artist is as permanent an achievement as the discovery by a great scientist.

    The English language is full of phrases about the weather. Some of these phrases are easy to understand, but others are not really about the weather at all. If you say you "hit rough weather", you may not be struck by a real storm, but you do experience difficulties or problems. If you don't know what such phrases mean, they might leave you "in a fog (雾)"!

    In English, you can "shoot the breeze", or have an informal chat. But things can also be a breeze. If you take an exam and find it very easy, you'd tell your friends: "It was a breeze!" The wind can also bring information. You can "get wind of" a piece of news, and if someone "knows which way the wind blows", they have a good idea about how things will work out. But don't "throw caution (警惕) to the wind" — that means taking a great risk!

    Clouds sometimes bring rain, and in English they often represent problems or difficulties. If someone "sees a cloud on the horizon (地平线)", there may be problems ahead. And if someone is "under a cloud", then people think the person might have done something wrong. But clouds are not always bad; in fact, people say that "every cloud has a silver lining". This means that there is a good side to every situation, no matter how bad it may seem. You may even end up "on cloud nine", which means you are very happy! But some people have their "heads in the clouds", not paying attention to reality.

    No one likes to be stuck in the rain or storm, so it's no surprise that phrases about them are generally negative. When someone says "it never rains but it pours", they are complaining (抱怨) that when things go wrong, they go very wrong. People who talk about "weathering a storm" just want to get through a difficult period or situation.

    In the short time Steve and Zach had been inside their tent packing their tools, wind-blown flame had skipped from the top of one tree to another. The long dry summer had turned the forest into a tinderbox.

    "Let's go! We can make it back to the river we crossed today!" Steve kept Brady on the lead and their heads down against the fire-wind. But Brady barked a sharp warning. Ahead of them lay a thick curtain of smoke across the track. They would never make it through that. The dog was pulling at his lead trying to draw them away from the smoke, and yet Steve was uneasy. It seemed to him that they were moving away from the river.

    Suddenly, Zach cried. "Zach!" Steve shouted. "Are you OK? Where are you?" Then Brady pulled Steve down a sharp slope(坡). At its base, Zach was rubbing his ankle.

    As Steve helped his friend to his feet, Brady lifted his head and snuffed(嗅) the smoke-laden wind. Next moment, the dog bounded away and disappeared. The boys shouted for him, but he didn't come back. Steve couldn't blame Brady for panicking. He himself wanted to run even though he didn't have a clue which way.

    Steve and Zach hadn't gone far when there was a familiar bark, and Brady came bounding, stopped directly in front of Steve and hit him with his head, pushing him back toward the slope they'd just climbed. But Steve didn't get it. Then Brady grabbed the boy's jeans and started pulling. The message was clear, but Steve hesitated. Of course he remembered Brady saving his uncle's life when the dog was much younger. Was he still sharp enough to get them through this?

    Nearby, a pine went up in a whoosh of smoke. Brady pulled again, urgently. "OK, big guy," Steve gritted(咬紧牙关). Brady led them back down the slope and into the trees. Not far from them fire was touching underbrush. Several times the big dog stopped. Often he changed directions. Steve was so tired that he just wanted to rest, but Brady wouldn't have it. The dog bullied both boys to go on. How long they'd walked Steve had no idea. He was almost numb when he heard it—the wonderful sound of rushing water!

    The largest-ever study of the link between city walkability and high blood pressure has been considered as evidence of the "invisible value of urban design" in improving long-term health outcomes, say researchers. The study of around 430,000 people aged between 38 and 73 and living in 22 UK cities found significant connections between the increased walkability of a neighborhood and reduced risk of high blood pressure among its residents (居民).

    The results remained the same even after lifestyles and physical environment were changed, though the protective effects were particularly pronounced among participants aged between 50 and 60, women, and those living in heavily populated areas and poor neighborhoods.

    The paper was published in the International Journal of Hygiene and Environmental Health. With high blood pressure a major risk factor for chronic (慢性的) and particularly heart diseases, researchers at the University of Hong Kong and Oxford University said the findings showed the need to take notice of the health-influencing factor in urban design.

    "We are spending billions of pounds in preventing and curing heart diseases — if we are able to invest in creating healthy cities through small changes in the design of our neighborhoods to make them more activity-friendly and walkable, then probably, we will have significant savings in future healthcare expenses."

    Poorly designed spaces generally reduced walking and physical activity, promoting the lifestyles of long time sitting down and not moving, and were harmful to social communication, and as such related to poorer mental and physical health.

    Because walkability was “based on the potential (潜在的) design of the city", said Dr. Chinmoy Sarkar, cities could be adapted or designed to encourage it. “Such investments in healthy design are likely to bring in long-term gains as they are lasting and common."

    When the company was small, Google cared a lot about getting kids from Harvard, Stanford, and MIT. But Laszlo Bock, Google's former Senior Vice President of People Operations, said it was the "wrong" hiring strategy. Experience has taught him that there are exceptional kids at many other places, from state schools in California to those in New York. "What we find is that the best people from places like these are just as good if not better as anybody you can get from any Ivy League school," said Bock, who authored a book titled "Work Rules!"

    So what else does Google not care about:

    Grades: Google's data shows that grades predict performance for the first two years of a career, but do not matter after that.

    Brain-teasers: Gone are interview questions such as: Why are manhole covers (井盖) round? How many golf balls can fit in a school bus? "Our research tells us those questions are a waste of time," Bock said. "They're a really coachable skill. The more you practice, the better you get at it."

    Here's what Google does care about:

    Problem solvers: Your cognitive (认知的) ability, or how well you solve problems.

    Leaders: The idea is not whether you were president of the student body or vice president of a bank, but rather "When you see a problem, do you step in and help solve it?" and then critically, "Are you willing to let somebody else take over, and make room for somebody else? Are you willing to give up power?"

    Googleyness: That's what Google calls its cultural fit. It's not "Are you like us?" Bock said. "We actually look for people who are different, because diversity gives us great ideas."

    "What's most important is that people are intellectually humble, willing to admit when they're wrong, and care about the environment around them ...because we want people who think like owners not employees," Bock said.

Bullying on campus is increasingly becoming a problem, but the move by the Sherrard School in California, to set equipment inside toilets to catch bullying incidents is getting a lot of attention.

The school has put up a campus alarm system in sensitive places such as toilets that employs voice recognition and sensitive word activation, so that if someone is being bullied, the system can alert members of staff by sending specific signals. The system uses artificial intelligence for voice recognition, but its effectiveness doesn't depend only on these technologies. More important than the technology are the members of the school staff that are arranged to respond quickly and effectively to the warning calls.

Basically, technology serves as a way of reporting instances of bullying to the school authorities. What is truly noteworthy is the authorities' realization that timely intervention is required to stop bullying. In most cases of bullying in schools, educators and the administrators have overlooked early warning signs. And this can, at times, prove fatal. For instance, in a recent tragic case in Indiana, three junior school students plotted and took the life of their 10-year-old classmate. If the school had paid closer attention to the bullying, the tragedy could perhaps have been prevented. 

Returning to the system in California, should it prove effective, relevant government bodies can consider applying similar mechanisms in other schools to hold back bullying on campus. However, it is significant for them to bear in mind that it is human action, not just technology, that can help address this universal issue. Technology can definitely serve as a vital tool, but it is the human element — attentiveness, care, and timely intervention — that ultimately holds the key to creating a safer environment for all students.
