Food storing is common in members of the crow（乌鸦）family. A new study tested the birds outside this naturally occurring behaviour, which may have evolved（进化）specifically because it gives crows a survival advantage. Some crow species are known to naturally use tools to recover food. So the researchers tested whether the birds could store and recover a tool so they could get it at their food after a gap of 17 hours—something we wouldn't expect them to do naturally. But they were able to instantly select the tool out of a number of unnecessary items.

    In another experiment, the researchers taught crows to select a token （礼品券）from a number of items so that they could then exchange for food. Again, the birds then showed that they could plan for the future using this new behaviour. This is different from all of the previous studies in future planning, which have focused on naturally occurring behaviour. For example, we know that chimpanzees select, transport and save appropriate tools for future needs.

    These studies have shown that animals can plan for the future—but they left an important question open for debate. Are animals only able to plan to use abilities that have evolved to give them a specific advantage, or can they flexibly and intelligently apply planning behaviour across various actions? Most critics would say the former, as the animals were tested in naturally occurring behaviours.

    But the new research provides the first evidence that animal species can plan for the future using behaviour that doesn't typically occur in nature. This supports the view that at least some recognitive abilities in animals don't evolve just in response to specific problems. Instead, it suggests that animals can apply these behaviours flexibly across problems in a similar way to humans. We need to investigate how flexible behaviour evolved. Then we might be able to see how crows' ability to plan for the future fits in with their broader cognitive powers.

    Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are concerned with their own appearance and actions too much. Negative thoughts are constantly occurring in their minds: What kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes?

    It is obvious that such uncomfortable feelings must affect people unfavorably. A person's self-concept is reflected in the way he or she behaves and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a deep effect on all areas of their lives.

    Shy people, who have low respect, are likely to be passive and easily influenced by others. They need faith that they are doing "the right thing". Shy people are very sensitive to criticism. It makes them feel inferior（自卑）.They also find it difficult to be pleased by praises because they believe they are unworthy of praise. A shy person may respond to a praise with a statement like this one: "You're just saying that to make me feel good, I know it's not true.” It is clear that, while self-awareness is a healthy quality, overdoing it is harmful.

    Can shyness be completely got rid of, or at least reduced? Fortunately, people can overcome shyness with determination since shyness goes hand in hand with lack of self respect. It is important for people to accept their weakness as well as their strengths. Each one of us has his or her own characteristics. We are interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our chances for a rich and successful life.

    About aspirin (阿司匹林):

    Aspirin is a commonly used drug which can be taken to relieve discomfort caused by numerous medical problems including headaches, toothache, inflammation(发炎) and infections. It is also suitable to treat colds and flu-like symptoms(症状), and to reduce a high temperature.

    Who can take aspirin? Adults and children over 16 years of age.

    Who should not take aspirin? Women who are pregnant, or plan to become pregnant. Aspirin may harm your unborn baby.

    Women who are breast-feeding. Aspirin can pass into your breast milk and may harm your baby. People who have any problems with the way the liver works or with the way the kidneys work.

    How to take aspirin: Take aspirin after meals, with a full glass of water or milk.

    The recommended dose (剂量) ranges from two to three tablets at a time. Never take more than 4g 12 tablets) in any 24 -hour period. You must not take these tablets with any other medicine which contains any aspirin or painkiller.

    How to store aspirin: Keep all medicines out of the reach and sight of children.

    Store aspirin in a cool, dry place, away from direct heat and light.

    Do not put aspirin in the bathroom because the dampness there can cause it to lose its effectiveness. Throw away aspirin that smells strongly of vinegar.

    Possible side effects: Feeling sick, increased risk of bleeding, stomach pain, indigestion and heartburn are common. If these effects continue, contact your doctor. Ringing in the ears, difficulty breathing, dizziness, and mental confusion are rare. If these occur, stop taking the drug and contact your doctor for further advice.

    Like many other people who speak more than one language, I often have the sense that I'm a slightly different person in each of my languages­more confident in English, more relaxed in French, more emotional in Czech. Is it possible that, along with these differences, my moral compass (指南针) also points in somewhat different directions depending on the language I'm using at the time?

    Psychologists who study moral judgments have become very interested in this question. The findings of several recent studies suggest that when people are faced with moral dilemmas (困境), they do indeed respond differently when considering them in a foreign language than when using their native tongue.

    In a 2014 paper led by Albert Costa  volunteers were presented with a moral dilemma known as the "trolley problem": imagine that a runaway trolley is moving quickly toward a group of five people standing on the tracks, unable to move. You are next to a switch that can move the trolley to a different set of tracks, therefore sparing the five people, but resulting in the death of one who is standing on the side tracks. Do you pull the switch?

    Most people agree that they would. But what if the only way to stop the trolley is by pushing a large stranger off a footbridge into its path? People tend to be very hesitant to say they would do this, even though in both situations, one person is sacrificed to save five. But Costa and his colleagues found that presenting the dilemma in a language that volunteers had learned as a foreign tongue dramatically increased their stated willingness to push the sacrificial person off the footbridge, from fewer than 20% of respondents working in their native language to about 50% of those using the foreign one.

    Why does it matter whether we judge morality in our native language or a foreign one? According to one explanation, such judgments involve two separate and competing ways of thinking­one of these, a quick, natural "feeling," and the other, careful deliberation about the greatest good for the greatest number. When we use a foreign language, we unconsciously sink into the more careful way simply because the effort of operating in our non-native language signals our cognitive (认知的) system to prepare for difficult activity.

    An alternative explanation is that differences arise between native and foreign tongues because our childhood languages are filled with greater emotions than are those learned in more academic settings. As a result, moral judgments made in a foreign language are less filled with the emotional reactions that surface when we use a language learned in childhood.

    There's strong evidence that memory connects a language with the experiences and interactions through which that language was learned. For example, people who are bilingual (双语的) are more likely to recall an experience if reminded in the language in which that event occurred. Our childhood languages, learned in the middle of passionate emotion, become filled with deep feeling. By comparison, languages acquired late in life, especially if they are learned through limited interactions in the classroom or dully delivered over computer screens and headphones, enter our minds lacking the emotionality that is present for their native speakers.

There's a useful concept from psychology that helps explain why good people do things that harm the environment: the false consensus effect. That's where we overvalue how acceptable and prevalent（普遍的） our own behavior is in society. Put simply, if you're doing something （even if you secretly know you probably shouldn't）, you're more likely to think plenty of other people do it too. What's more, you likely overestimate how much other people think that behavior is broadly OK.

This bias（偏见） allows people to justify socially unacceptable or illegal behaviors. Researchers have observed the false consensus effect in drug use and illegal hunting. More recently, conservationists are beginning to reveal how this effect contributes to environmental damage.

In Australia, people who admitted to poaching（偷猎） thought it was much more prevalent in society than it really was, and had higher estimates than fishers who obeyed the law. They also believed others viewed poaching as socially acceptable; however, in reality, more than 90% of fishers held the opposite view. The false consensus effect has also shown up in studies examining support for nuclear energy and offshore wind farms.

Just as concepts from psychology can help explain some forms of environmental damage, so too can they help address it. For example, research shows people are more likely to litter in areas where there's already a-lot of trash scattered around; so making sure the ground around a bin is not covered in rubbish may help.

Factual information on how other people think and behave can be very powerful. Energy companies have substantially reduced energy consumption simply by showing people how their electricity use compares to their neighbors. Encouragingly, stimulating people's natural desire for status has also been successful in getting people to "go green to be seen", or to publicly buy eco-friendly products.

As the research evidence shows, social norms can be a powerful force in encouraging and popularizing environmentally friendly behaviors. Perhaps you can do your bit by sharing this article!
