Doctors say anger can be an extremely harmful emotion, unless you learn how to deal with it. They warn that angry feeling can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

    Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm, reasonable way. Others burst with anger, losing control of themselves. But still other people control their anger. They cannot or will not express it.

    For years many doctors thought that controlling one's anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain lets out the same hormones that are produced during tense situations. They speed the heart rate, raise blood pressure, and narrow the blood vessels. In general, the person feels excited and ready to act.

    Doctors said that controlling these feelings only makes the feelings continue. And this can lead to many medical problems. Doctors thought a person could prevent these problems by letting the anger out by expressing it freely. But recently some doctors held a different view. They said that people who express anger too often and violently did become, in fact, more and not less angry. They said this, too, can cause medical problems.

    Some doctors say that both controlling and expressing anger can be dangerous. They believe that those who express anger strongly may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

    Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

    Since his students began using Quizlet, English teacher Tristan Thorne has noticed an improvement in their ability to learn and use new words. Quizlet is a learning App, a computer program you use on your mobile phone. It can help users build and test their knowledge of English words. Quizlet has word sets for millions of subjects. And, it is quickly becoming a useful mobile tool for language learners.

    Thorne teachers at Columbia University in New York City. Thanks to learning Apps, Jeff Strack, another English teacher, has also notice improvement in his students' ability to remember information. He teaches at Hostos Community College, also in New York. He and Thorne are part of a growing number of language educators adding mobile Apps to their classes.

    Strack and Thorne seem to agree that the days when teachers would not permit the use of mobile phones are gone. When they use Apps, language learners communicate more differently than in a traditional classroom. Users act on or respond to something, instead of just listening to new information.

    Thorne believes that Apps can help learners become more active in learning. For example, each week, his students are required to add vocabulary words into Quizlet for others to use. He says some Apps also make it easy for students to know their language strengths and weaknesses.

    The biggest improvement Strack has seen in his students is that they are much more active inwhole-class or small-group discussions. “Apps let all students take part in the activity, whether it's a game, quiz or practice activity.” he says.

    Many existing learning Apps are designed for students of all ages and levels. Some are designed for group activities. Some support independent learning. Still some are good for homework. Thorne says he especially likes Quizlet and three other Apps: QR Codes, Socrative and Evernote.

    Australia is a developed country and the future of its solar industry is looking bright after a record 3.5m panels (嵌板) were installed on rooftops last year, giving the equal output of a medium-sized coal-fired power station. The record 1,057 MW of capacity (生产能力) in small-scale systems installed across the country broke the previous record set in 2012, figures from the Clean Energy Regulator showed on Tuesday.

    Australia's solar power prosperity could almost double capacity in a year. The data also revealed that the average system size has also doubled since then from three to six kilowatts as average prices continued to fall. A fully installed 5KW system costs an average of $5,930 in Australia, according to the energy broker Solarchoice. net. au. Its records show that the price has roughly halved in many capital cities since 2012.

    The regulator's executive general manager, Mark Williamson, said there was increasing interest in renewals as a way to take control of electricity bills. But more importantly, he said it was also good news for reducing carbon emissions.

    “We are seeing a wide cross-section of Australians-households, community centers, schools, and small businesses-receiving rewards under the small-scale renewable energy scheme,” Williamson said. “Our data shows consumers are embracing renewable energy to take control of their electricity bills.”

    In 2017, there was a 41% increase in installing renewable energy capacity across all states and territories compared to 2016. Queensland led the way with installed capacity at 295MW, with the Australian Capital Territory taking top place for the biggest annual increase by 57%. “The data collected by the Clean Energy Regulator in 2017 reflects the industry is going from strength to strength. It looks like 2018 will be another big year for the solar industry.”

    The total of installed capacity for last year is expected to rise to 1,070MW when all the data is collected. A large coal-fired power station such as Loyd Yang A in Victoria's Latrobe Valley has a capacity of 2,200MW.

    Most of us feel very tired after working for eight hours a day, five days a week. When we get home, we watch at least one film because it's well-deserved and the only time we get to "relax" before going to sleep. Wake up and repeat. No wonder you feel tired. So how do you get out of this vicious circle? How do you restart your life?

    ⒈YOUR MINDSET

    "Oh man, another one of these self-improvement things. I hope I can do it, but I've tried these things before, and I just never stick to it."

    This was something I used to say to myself every time I try to start something new for myself. There's a fear-driven side of your brain which tells you, "You can't do this."

    What can you do? Well, the tip here is to talk to yourself like you're talking to a friend, or a coworker. So the next time you try something new, be kind to yourself like you would be kind to others. You are your own worst critic. But you can also be your firm defender.

    ⒉YOUR DIET

    If you are looking at what you eat for the reason to feel energized, then the general rules are:

    1) Eat when you're hungry. Don't eat when you're not.

    2) Be mindful when you eat. Chew at least 20 times. Let yourself taste and digest your food.

    3) Don't do three things at once when you're eating. Your body wasn't made for that.

    4) Preferably, eat "real" food. Eat what your great-grandmother would recognize as food.

    Don't let your days pass by in a boring way. Start by re-examining these key habits in your life to build a body that can start doing things you want.

    ⒊YOUR SLEEP

    Without enough sleep, we're basically going through the day drunk. This means tiredness, difficulty to respond quickly and smartly to anything that comes up. The sleeping hours needed for an average adult ranges from 7 to 9 hours.
