The world is filled with smart ，educated and gifted people. We meet them every day. A few days ago ，my car was not running well. I pulled it into a garage and the young mechanic fixed it in just a few minutes. He knew what was wrong by simply listening to the engine sound. I was amazed. The sad truth is that great talent is not enough.

    I am constantly shocked at how little talented people earn. I heard the other day that less than 5 percent of Americans earn more than $100，000 a year. A business consultant who specializes in the medical trade told me how many doctors and dentists struggle financially. It was this business consultant （顾问）who gave me the phrase ，“They are one skill away from great wealth.”

    There is an old saying that goes，“JOB means  'Just Over Broke（破产）”. And unfortunately，I would say that the saying applies to millions of people. Because schools do not think financial intelligence is intelligence，most workers “live within their means”. They work and they pay the bills. Instead I recommend that young people seek work for what they will learn ，more than what they will earn.

    When I ask the classes I teach ，“How many of you can cook a better hamburger than McDonald's ？ ” almost all the students raise their hands.I then ask ，“So if most of you can cook a better hamburger ，how come McDonald's makes more money than you？” The answer is obvious: McDonald's is excellent at business systems.The world is filled with talented poor people.They focus on perfecting their skills at building a better hamburger rather than the skills of selling and delivering the hamburger.

    Patients with light or moderate depression can be successfully treated by swimming with dolphins, researchers said on Saturday.

    The study was carried out in Honduras, including patients who were thought by the doctors with light of moderate depression coming from the United States and Honduras.

    For two weeks, half of the group swam and snorkeled (潜泳) with dolphins for an hour a day. At the same time the other half group carried out the same type of water activities, but with the absence of dolphins. Researchers want to find out the influence of water and the natural setting.

    All the study volunteers didn't continue to take any drugs or psychotherapy ( 心理治疗) at least for weeks before the start of the study and did not take any drugs during the study, said the researchers from the division of clinical Psychiatry at t e the University of Leicester Medical School.

    By the end of the study, those people who swam with the dolphins had a greater average reduction in their depressive symptoms than those who did not.

    The researchers noted that the study supports the theory of biophilia, which thinks that human health and well-being depends partly on the human connection with the natural world. The findings appeared in the issue of the British Medical Journal.

    Coming from the Greek, biophilia means “love of life”, and it has been developed by biologists to reflect the humans' natural tendency to connect with nature and animals, leading to interactions and positive emotions that result in psychological treatment.

    Crown shyness(树冠羞避) is a mysterious natural phenomenon in which the crowns of some tree species do not touch each other, but get separated by a gap clearly visible from ground level. The effect usually occurs between trees of the same species, but has also been observed between trees of different species.

    There are many theories going around, most of which make sense, but no one has been able to prove without the shadow of a doubt why some trees avoid touching each other.

    In his 1955 book Growth Habits of the Eucalypts, Australian forester M.R. Jacobs writes that the growing tips of the trees are sensitive to abrasion(擦伤), which results in crown shyness phenomenon. This theory was also supported by Dr. Miguel Franco. Some experiments have shown that if trees displaying crown shyness are artificially prevented from swinging in the wind and touching each other, they gradually fill up the gaps between them.

    But while the above theory is arguably the most widespread, it's certainly not the only one. Some scientists have suggested that crown shyness is a mechanism to stop the spreading of leaf-eating insects. These pests have been known to work together and create structures that extend up to 10 cm off of tree branches in order to reach other plants, so the gaps are the trees' natural defense method.

    One Malaysian scholar studied many trees, but found no traces of abrasions, despite their clear crown shyness. Instead, he suggests that the growing tips of the trees were sensitive to light levels and stopped growing when they got too close to other trees. Plants are able to sense how close they are to other plants and in order to get more light, they give off some chemical element to stop other trees from growing too close.

    Whatever the reason, one thing is for sure: plants are more intelligent than people used to think.

    We Brits love the idea of a real Christmas tree but not so many of us like the realities of dragging (拖拽) a 7ft Norway Spruce through the house and leaving needles all over the place.

    If you count yourself among the reluctant group, then it may be time to go fake (假的) . After all, buying an artificial Christmas tree needn't mean accepting defeat. There's a huge range of choices and sizes, including pre-lit trees, which will save you the frustration of trying to string your own lights.

    Another big advantage of choosing an artificial Christmas tree is cost: artificial trees can last for decades, so they work out cheaper than paying for a real tree every year. Like now retailers (零售商) are offering great deals at the moment: at Tesco, there's 25 percent off artificial Christmas trees. Meanwhile, you can take advantage of the current 3 for 2 offer at Argos to fill your house with not one, not two, but three. You may perhaps partner up with friends who are also looking to invest.

    Of course, keep your tree for years and years and it will start to pay you back in terms of carbon footprint; however, a “real” one will always have to be transported, used and dealt with every year.

    Are there any downsides? Yes. You might think you're saving the planet, but a fake tree is actually not an environmentally friendly option. Most are made in factories in Asia, resulting in some serious air miles to reach the UK. They're made from metal and plastic, and many end their lives in landfill (垃圾填埋).

    Another problem with a fake tree is that they don't look very natural and of course you won't get that lovely pine smell either. You'll also need to find space for storage.

    In the online world, it's very difficult to talk to Chinese people without using emojis. However, did you know that people in different age groups have totally different preferences for choosing their emojis? The result is based on a report released by Tencent's WeChat, China's most popular messaging app, on its official weibo account on Wednesday.

    Specifically, for users who were born in the 2000s, their favorite WeChat emoji would probably be the widely used "facepalm", rumored to be based on the famous Hong Kong movie star Stephen Chow. They also may be a night owl without much sleep, while iced beverages and desserts are their cup of tea.

    For China's post-90s WeChat users, they are likely to get out of bed later in the morning compared with other groups, and the emoji "face with tears of joy" may rule their online social life. Also, their reading materials have shifted from entertainment and gossip three years ago to the current relationship and lifestyle pieces.

    For those born in the 1980s, their tastes have remained the same, as they are still fond of reading news on national affairs. And "smiling widely" is their emoji of the year.

    WeChat users born in the 1970s are called the optimistic group, who like to use the emoji "laughing quietly" and go through their moments frequently every day. Their bed time usually takes place around 11:30 pm.

    Users over 55 are the early-bird group with rich entertainment activities in WeChat platforms, such as looking through moments, reading and shopping. They like to cheer up other age groups, so their favorite emoji is "giving a thumbs-up".

    The report also indicates that WeChat boasts more than 1.08 billion active users with 45 billion messages being sent and 410 million calls getting through the app each day in 2018. In addition to covering users' socializing, WeChat has gradually come into our daily lives. Compared to the year before, people used WeChat 4.7 times more to purchase public transport tickets, and 2.9 times more to pay for medical expenses. Also, the app was used 1.5 times more over the previous year to pay for meals, with Beijing, Guangzhou and Shenzhen ranked as the top three cities in dining purchases through WeChat.
