More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

    Get on a bicycle and ride around your neighbourhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car.

    You can bike to work and benefit (受益) from the enjoyable exercise without polluting  the environment. You don't even have to ride all the way. Folding (折叠) bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travellers.

Health Benefits of Bicycling:

    It helps to prevent heart diseases.

    Bicycling helps to control your weight.

    A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a year.

    Bicycling can improve your mood (心情).

    Exercise like bicycling has been shown to make people feel better, more relaxed and self-confident.

    Bicycling is healthier than driving.

    There was a doctor in our city who was famous for his skills. Once he received a little child who was badly ill. Thanks to his skill and care, his young patient got well and was soon able to get up and run about again.

    The child's mother was very much thankful to the doctor, and she visited him to thank him for what he had done for her child. “Doctor,” she said, “you have saved my little son. I don't know how to thank you enough. I feel that money alone cannot repay you, so I have made this little purse with my own hands, as a sign of my gratitude. I hope you will accept it.” The doctor stood up and said coldly, “Madam, a little present like that is very nice between friends, but a doctor needs to be paid properly for what he has done.” The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, “Perhaps you will tell me how much your fee is?”

    “Fifty pounds”, he answered.

    The lady opened the little purse and took out four fifty-pound bank notes. She handed one of them to the doctor, and put the other three back into the purse. She put the purse into her handbag and, saying good bye to the doctor, went out of the room.

    September is an exciting month in every college freshman's life. For many, it's the first time that they've left home to live in a new environment. But after the hustle and bustle（喧嚣）of a few weeks, excitement gives way to a less enjoyable emotion— homesickness.

    Homesickness manifests（显露）itself in many ways. You may miss mum's cooking, your pets, or even your old bed. All this becomes a fond memory of the past. Homesickness can be a bitter feeling for many students, especially when faced with the challenges of settling into an unfamiliar environment.

    But remember, you're not alone. According to a recent BBC article, 70 percent of British college students experience homesickness. In this increasingly globalized world in which people migrate to faraway places for a relationship, education or work, homesickness is a feeling shared by many adults.

    Homesickness can have similar symptoms to depression and in extreme cases it can develop into a panic attack. As for the term, homesickness or nostalgia wasn't invented until the 17th century. It was considered a disorder by a Swiss physician, who attributed soldiers' mental and physical discomfort to their longing to return home, “nostos” from Greek, and the accompanying pain, “algos”.

    Studies in recent years, however, have shown that nostalgia may have some benefits to our mental health. After a decade of surveys and researches, Constantine Sedikides, a US social psychologist, found that nostalgia is what makes us human. He explains that nostalgia can resist loneliness, boredom and anxiety. Therefore, it's necessary for college students to learn some ways to overcome the uncomfortable feeling.

    Why we cry with happiness show: Responding with a negative reaction helps us deal with extreme joy. If you cry with happiness at weddings, you are responding to a happy experience with a negative reaction. The researchers believe the unusual reaction may help renew emotional balance in us and keep extreme emotions under control. The findings make it clear how people express and control their emotions, which could help improve their understanding of people's mental(精神的) health.

    Dr Oriana Aragon set out to explore the phrase “tears of joy”, which she said never made sense to her. But after studying a series of incongruous(不和谐的) expressions, she now understands better why people cry when they are happy. “People may be renewing emotional balance with these expressions,” she explained. “They seem to take place when people are struck by strong positive emotions. People, who do this, seem to recover better from those strong emotions.”

    The report show various examples of responding to a positive experience with a negative emotion, such as, a crying wife seeing the husband returning from war again, and teenage girls screaming at a Justin Bieber concert. Examples also include a baseball player who hits a home run, only to be slapped(拍) on the back by teammates, as well as when people cannot help kissing babies' faces who they consider lovely.

    Dr Aragon and her team discovered that people, who expressed negative reactions to positive news, were able to moderate(缓和) strong emotions more quickly. There is also some evidence that strong negative feelings may provoke positive expressions. For example, nervous laughter often happens when people are faced with a hard situation. We've seen people smiling during times of extreme sadness.

    “The findings affect our knowledge of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together,” Dr Aragon said.

    Monty Hempel is a professor of environmental sciences at Redlands University in California. He studies ecological literacy­or eco-literacy, for short. Eco-literacy is the ability to think about and understand the natural processes that make life possible.

    Monty Hempel says eco-literacy gives people knowledge about environmental problems. But he says it does not always work on getting them to change their behavior.

    Mr. Hempel wrote part of the Worldwatch Institute's latest State of the World report. He says in his article, "Some people think that eco-literacy is just a green form of science literacy. And what I have tried to ask is whether that's enough. In other words, what an ecologically-literate person needs to know might include things like the effect of environmental pollution on ecosystem, the energy systems, and all of those kinds of things that we would call the science of ecology."

    "That doesn't seem to lead to action to protect our environment ­ to protect our life-support system to the level that we need to. Just knowing a lot about the environment doesn't mean that we actually act to save it. After all, actions speak louder than knowledge."

    He adds that people may not be very worried about environmental problems if they seem far away. "Some people call it psychological distance. A lot of climate issues are worse in the Arctic and most of us don't spend time in the Arctic. And so, there's a certain distance. But there's also a distance that's happening in the world as it urbanizes ­ people spending more time in front of screens and less time out in nature. We become, if you will, disconnected from the natural systems that used to be the key to success for a human being."

    To help children discover the wonders of nature, he adds that children should learn about nature in school. But he also points out we have a high mountain for people to climb from knowledge to action.
