Why I've taken a break from holidays

    It is now close to four years since I last took a holiday. This is because I have come to the conclusion, over the course of my adult life, that I am not very good at it. You might think this sounds like saying you're not very good at drinking tea or listening to music. What could possibly be difficult about the natural act of putting your working life on hold for a couple of weeks and going somewhere warm to do nothing?

    I was a model holidaymaker as a kid. However, the problems started during my twenties. A trip to the south of France was ended after just two days, mainly because I had an urge to check my e-mails. Similarly, my honeymoon was cut short by 48 hours—not because my wife and I weren't enjoying ourselves, but because we were missing our cats.

    So what is my problem? On the surface, I'm probably a bit of a homebody. And I just find the pressure of being on holiday too severe: it always feels like having a gun held to my head and being forced to have fun. Somehow, packing a list of possessions and meeting a scheduled flight has none of the excitement of suddenly deciding to take a day off and driving somewhere for the fun of it.

    Thankfully, I'm not alone. This summer, most of my friends have decided not to have a break. And a recent survey (调查) proved the downside of holidays, with the results showing that nearly two thirds of people found that the calming effects of a holiday wore off within 24 hours, as stress levels returned to normal. And this year The Idler magazine published its Book of Awful Holidays. Here you will find a list of the five most ecologically-damaging vacations it's possible to take, along with 50 painful holiday experiences voted for on The Idler website.

    What interests me is what the concept of a “holiday” says about our lives. For me, the point of living is to have a life you enjoy for 52 weeks a year. The more I like my life and the better I structure it, the less I want to go away. Maybe I'm an unusual person for not liking holidays, but I just feel the time when I'm not working is too valuable to waste on them.

    My students entered the art room with their usual eagerness to see what they would be learning in today's class. Little did they know they were going to be students for a new teaching method that is spreading the nation.

    I often use videos as previews and supplements (补充) to our art lessons providing students with a variety of artists showing their skills in real-life situations outside the classroom. Finding a new painting technique called glue batik(胶水蜡染),  I thought of something new I hadn't tried before!  How awesome would it be to learn a new technique together with artists? The lesson was planned, presented to the students without any introduction or set objectives. I also asked the students to watch and pause the video as often as they needed to.

    They watched as the artist explained and showed her skills, taking notes on her steps and results. After the video, they shared what they felt the artist's objectives were, her end result using art vocabulary as well as the steps they would need to know to present their own examples. Then they began creating their works using the glue batik technique.

    Surfing the Internet a couple of weeks later, I found that the teaching method I used sounded very familiar to a new movement in education called flipped teaching, which was developed by Jonathan Bergmann. He asked his students to watch video lectures at home and do exercises (homework) in class under supervision (监督). He found that grades went up and he also found time for other types of activities, which Bergmann states are more important than the videos.

    Back to my art class, the students were learning to get ideas, make predictions, and explain reasoning to their classmates. Together they compared, asked questions and made discoveries as they presented the technique.

    This player is neither the answer to Bafana Bafana's goal-scoring problem, nor holds any hope of being in the national team for the World Cup. But Mmane Koko trains every morning and is now used to playing soccer. She said, 'Before I can do my domestic(家庭的) jobs, I go to train every morning. This helps me keep my body healthy. I started exercising after my doctor told me that exercising can keep my body healthy.'

    Mmane Koko, aged 66, said if she had been exposed to soccer at an earlier age, she would have become a top South African striker and could have stolen the limelight from Noko Matlou, who helped South Africa achieve its best ever result in the African women's soccer cup. She encourages young people to start playing sports early and to continue into their old age as it helps to lower blood pressure and prevent obesity(肥胖症).

    She added that because soccer is not only about exercising, but also helps one to put bread on the table, it could make a difference socially. She also says soccer is a business and that clubs these days pay generously. Therefore if the young take sports seriously, they can make a living out of it. But this can only happen if our government participate in developing sports and building stadiums for future generations.

    Exercise does us a lot of good as Mmane Koko says. We can live longer and feel better through exercise. It gives us energy surprisingly enough! Regular exercise reduces our risk of all kinds of disease. It can help us relieve stress and anxiety, increase our endurance(耐力) and sleep better. Exercise can contribute to our mental well-being and helps treat depression. So if you want to stay fit, keep on exercising to keep your body healthy.

You might think people all over the United States have Wi-Fi—wireless Internet service—and mobile phones. But there is no such service in Green Bank, West Virginia, a tiny town four hours from the U.S. capital, Washington D.C. Fewer than 150 people live in Green Bank, which has two churches, an elementary school and a public library. It is also home to the largest radio telescope in the world.

    There is a ban on Wi-Fi in Green Bank, along with anything else that can create electromagnetic(电磁的)waves. Officials say the waves could disturb the signals the telescope receives.

For many Americans, a visit to Green Bank is a little like returning to the 1950s. To get there, you must read road signs—because there is no GPS service in the town. People can connect with the Internet through telephones, but wireless service is not allowed.

    The observatory(天文台)is one of the largest employers in the area. The federal National Science Foundation(NSF) spends about ＄8.2 million a year to operate the observatory, telescope and educational center.

    Jonah Bauserman is a technician. If he supposes there is signal that is not allowed in the zone, he drives to the house where the signal is coming from and checks it. But once a week, when the device is cleaned, some banned devices are allowed near it.

    People in the town respect the work of the scientists. And they say they are happy to live without Wi-Fi and mobile phones. “You know, instead of sitting here on our phones and other devices we're out fishing and hunting and going to each other's houses.” Everyone knows each other and communication is almost always face-to-face.

Both humans and animals have enemies. 11 is easy for us to know the difference between our friends and our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who mean a threat and those who do not. In Kenya, researchers find that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men hunt animals and thus mean a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.

In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants noticed the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they noticed the smells of either clean clothing or clothing worn by a Kamba man.

Clothing color also plays a role. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted angrily toward the red clothing.

The researchers believe that the elephants' emotional reactions arc due to their different senses of smell and sight. Smelling a possible danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.
