Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

    Years ago, over hunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

    The 21st century brings a different challenge to elephant conservation —land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

    Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

    AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

    The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.

Happiness begins from appreciation

    If you are feeling that life just cannot be any worse for you, it can be challenging to think positive. When stressed, depressed, upset or otherwise in a negative state of mind because you are aware that misfortune keeps occurring, it is important to shift those negative thoughts to something positive{#blank#}1{#/blank#}

    It is often very hard to think positive when so many things are negative, but be sure that someone, somewhere is worse off than you{#blank#}2{#/blank#} If you start with one small, positive thing and appreciate it during the course of your day, you will begin to move into a more positive situation and people will start showing up in your life. With appreciation, you will find that over time, you will change your outlook and choose to be happy, regardless of the events around you{#blank#}3{#/blank#}

    Begin and end each day with a “Thank you for this wonderful, glorious day!”

    When you see the rise of gas prices, say “I am so glad to have a vehicle in which to get around.”

    When your boss is too hard on you, say “I am grateful for my job as I know that many don't have one.”

    If you are having health problems, be grateful for what does work: “I really do appreciate it that my eyes see, my ears hear, my mouth tastes, my legs walk, my arms lift and my mind thinks and everything else works.”

    Write down what you're grateful for each day. In moments when you're feeling really down, read loud what you wrote previously{#blank#}4{#/blank#}If you practice this regularly, you will find your list getting longer and longer.

    The key is to move yourself into a positive thought and keep it there long enough to make it a moment of appreciation{#blank#}5{#/blank#}

A. This will certainly help uplift your spirits.

B. If not, you will only attract more misfortune.

C. It is of great importance to learn to be grateful.

D. The more you appreciate, the happier you'll be.

E. You have made some achievements in your career.

F. Here are a few common examples for you to practice.

G. You can choose to think differently by beginning with the smallest of steps.

    Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.

    Different cultures emphasize (强调) the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries -- like the UK or France -- people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.

    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.

    Two of the saddest words in the English language are "if only". I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying "Take the extra minute to do it right." I always try to live by the "extra minute" rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an "if only" moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.

    I don't only avoid those "if only" moments when it comes to safety. It's equally important to avoid "if only" in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say "I love you" or "I forgive you." When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn't be here. But then I thought about the fact that he was 84 years old and I realized that I shouldn't give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say "if only" about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I'm doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

    How do young children learn to have good values? How can parents teach their children about the importance of kindness and patience? At a time when more and more parents worry about the violent images(暴力形象) their children see on TV, some are turning to fairy tales(童话).

    It is believed that fairy tales have a great influence on children because they describe the two sides of good and evil(邪恶) very clearly. When children hear the stories, they learn to care about others' feelings. In each tale, they can see that there are many different kinds of people in the world and that we all have a choice about what kind of person we want to be. We can choose to do good actions, rather than bad ones, in our lives.

    What kind of values can children learn from fairy tales? In The Princess and the Pea(《豌豆公主》), a poorly dressed girl, who insists she is a princess, is given a difficult test by the Queen. When she passes the test, we learn that her dream comes true because she stays true to herself. In The Little Mermaid(《小美人鱼》), the mermaid, who lives under the sea, wishes to be with the humans on land. Through her experiences, we learn about the importance of living with and accepting other cultures. In Pinocchio, a wooden puppet(木偶) turns into a boy when he finally learns how to tell the truth.

    Teaching values is the reason most often given for encouraging children to read stories. These fairy tales can teach children lessons about human relationships that are accepted around the world for many countries. This might be the reason why they have been around for so long and will not disappear any more soon.

    Modern lifestyles are generally quite different from those of our hunter-gatherer ancestors, a fact that some claim as the cause of the current rise in global obesity, but new results published July 25 in the open access journal PLOS ONE find that there is no difference between the energy expenditure(耗费) of modern hunter-gatherers and Westerners, casting doubt on this theory.

    The research team behind the study, led by Herman Pontzer of Hunter College in New York City, along with David Raichlen of the University of Arizona and Brian M. Wood of Stanford measured daily energy expenditure among the Hadza, a population of traditional hunter-gatherers living in the open Savannah of northern Tanzania. Despite spending their days hiking long distances to seek for wild plants and game, the Hadza burned no more calories each day than adults in the U.S. and Europe. The team ran several analyses accounting for the effects of body weight, body fat percentage, age, and gender. In all analyses, daily energy expenditure among the Hadza hunter-gatherers was indistinguishable(难以区分的) from that of Westerners. The study was the first to measure energy expenditure in hunter-gatherers directly; previous studies had relied entirely on estimates.

    These findings overturn the long-held assumption that our hunter-gatherer ancestors expended more energy than modern populations, and challenge the view that obesity in Western populations results from decreased energy expenditure. Instead, the similarity in daily energy expenditure across a broad range of lifestyles suggests that habitual metabolic(新陈代谢的) rates are relatively constant among human populations. This in turn supports the view that the current rise in obesity is due to increased food consumption, not decreased energy expenditure. It means we have more to learn about human physiology(生理学) and health, particularly in non-Western settings.

    "These results highlight the complexity of energy expenditure. It's not simply a function of physical activity," says Pontzer.” Our metabolic rates may be more a reflection of our shared evolutionary past than our diverse modern lifestyles."
