Maintain Speed

    Confident now?Great!Now the next step is to maintain your speed.While rolling in a straight line with one skate, with the other try sculling（划桨）,that is,keep pushing yourself backwards with an outwards stroke（滑动）.Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling.Now,try the same thing using the other foot.Again keep doing this till you are confident enough.

Increase Your Speed Now

    Once you are confident that you can scull with either foot,the next thing that you have to do is increase your speed.Try some of your own tricks now.Scull with either foot or with both at the same time. 

Scull and Be Aware

    What do butterflies have in common with the human spirit? Meet Maggie, a middle-aged wife and mother who was about to find out.

    Maggie wasn't rich like a millionaire or poor in a manner of being homeless. She was living an average comfortable life. It was made even better when a baby girl came her way. She and her husband made sure their daughter had her needs met and they were still able to take a yearly vacation by the beach.

    Maggie was a partner in her husband's business. They both had a different set of duties and everything was in balance. One day a severe blow came to her husband's business, and over a three-year period the business dropped out of sight. Her husband had to totally reinvent himself and was eager to start a new business. She was happy for him and supported him fully, but still the money was not coming in.

    Maggie began to feel guilty that she wasn't contributing with any kind of income. She began job-hunting and found filling out applications somewhat difficult, especially the part asking for job references. She was self-employed with her husband for almost 20 years, which seemed to mean nothing as she was never called for an interview.

    When she was job-hunting her mom became more ill than she had been and ended up in the hospital for a week. Once Maggie's mom returned home she became her mom's helper one day a week. She did everything that her mother was not able to do any more. Of course her mom would pay her for her lime and labor but she still felt she needed to find another source of income.

    One of the first applications she had filled out finally came through. She passed the interview and was told she was exactly what they were looking for. Although it was only part-time it was exactly what she wanted. It was important for her to be home when her daughter arrived home from school.

    Within a few weeks, though, she received an e-mail saying that the company had changed the job into a full-time position so that she was not qualified. Maggie felt betrayed and felt she had been lied to. That evening she was alone at home. She welcomed the aloneness and wanted to put herself in the bathtub to kill the lonely time.

    As she knew she would, Maggie began to cry, softly at first just from the sharp pain of being rejected. Three long years of struggle had finally overwhelmed her.

    When she was able to cry no more, she became worn out and gave up. It was at that moment that a silent idea came to her: why not offer elderly people home care assistance? Using another talent for computers she printed off some flyers and cards and distributed them to her church, grocery stores and even placed a small ad in the newspaper. Within a week she had procured two new customers. Now, even though she's not a CEO of a major company she feels happy and productive again.

    Before a butterfly can come out of its chrysalis (茧) it has to go through a lot of struggling. Each time it pushes out to escape, acids are being removed from its wings. If someone were to come along and break the chrysalis open for it then the butterfly would die from those acids. Actually the struggle is necessary for the butterfly to survive. Then in the stillness, when the struggle is over, the butterfly can come out and share its beauty with the world.

    We as humans are not any different.

    If you feel yourself turning into an old grouch(脾气坏的人), don't worry — happiness is just around the bend. A survey has found that although happiness dips in those in their 30s and 40s, people start to feel more content with life after the age of 50.

    However an economist found that older people will never again regain the excitement of youth. Rather it is thought that with age, individuals become more pragmatic about the ups and downs that life brings and accept their fortune.

    He questioned those in Britain, Switzerland and Germany and applied the findings to people's life cycle.

    Mr. Van Landeghem, 29, said:“A happiness curve does not necessarily imply that a 65-year-old prefers his own life to the life of a 25-year-old.”

    “Both the 25-year-old and 65-year-old might agree that it is nicer to be 25 than to be 65. But te 65-year-old might nevertheless be more satisfied, as he has learned to be satisfied with what he has.”

    It was suggested the mid-life happiness dip is because this is when people have the most responsibilities — taking care of a family, paying a mortgage (抵押贷款) and having a demanding career. The middle-aged dip in happiness was also compared to that of losing a close relative or suddenly becoming unemployed.

    The study is just one of many put forward as an indicator of what makes for a happy life.

    Psychologists concluded that having money makes you happier, but only if you have a lot more than your friends and neighbors. At the same time, you'd better have enough tie to enjoy yourself instead of spending all your time on making money.

    Separate research found that owning the house of your dreams, the car you always longed for and having millions in the bank doesn't stop that desire to keep up with the Joneses (攀比). And if the Joneses have more than you do, you'll be miserable. It seems envy at being lower in the social pecking order (权势等级) reduces the satisfaction of being well off.

    If you just do what you love and you are good at, which society also values much, you may have a higher probability to be happy. But if your job pays less, how can you stick to it in disregard of responsibilities? Happiness means different things from different points of view, and point of view grows from one's experience and knowledge. Perhaps it comes with you when you don't need to think about adult problems or when you are wise enough to understand what satisfaction is.

    Scientists in Western Australia claim to have made a new discovery—they have found gold in the leaves and twigs of trees. The researchers believe that the trees suck up the gold from deep underground, over 30 metres down. The discovery has been described as the first of its kind in the world. Australian gold exploration companies are pleased because it will make finding gold cheaper. Rather than drilling deep holes to find gold, they have more ways to examine tree leaves and branches. There is only a tiny amount of gold in the leaves. It would take 500 trees to make one gold ring. The gold is found using a special X-ray machine owned by an Australian government agency. A pure X-ray and a powerful microscope scan the leaves and branches.

    The claim that this is the first time that gold particles (微粒) have been found in living material might not be true, though. Ancient Chinese wisdom understood the connection between plants and the precious stones and minerals underneath them. They used plant life to find minerals and that was thousands of years ago. In the Zhou Dynasty, it was written in a book that a certain plant grew only near deposits of gold. Over the next 2,000 years, Chinese people wrote about different plants and how they grew, showed where minerals and precious stones such as jade, copper, lead, silver and gold were.

    Even more importantly, in the 1, 000s, Su Song described how copper, gold, silver, lead and tin were observed and taken from certain plants. These were amazing scientific discoveries. Meanwhile, this knowledge was unknown in the rest of the world until about 1, 600. This was when a British man realised that oak trees grew larger and greener where there was alum (明矾) in the ground. Maybe ancient Chinese has more knowledge to teach modern scientists.

You've probably heard it a dozen times by now. But here it goes again: Sleep is important. Your mental health and immune (免疫时)system are connected to your sleeping habits. So are your grades, a new study finds. Sleep accounts for nearly one-fourth of the difference among students' grades in a class. So even if you spend hours studying for a test but get too little sleep, you might still do poorly.

Typically, people's sleep schedules are messy and can not be known in advance. Professor Jeffrey Grossman of Massachusetts Institute of Technology in Cambridge wanted to see if sleep links to people's learning performance even when a study was done with people who kept such true-to-life schedules at home. So he turned to Fitbits, which can check how long people sleep and how frequently they wake up. And the researchers looked for 100 students. They focused on these students' sleep patterns in the days and weeks before exams and then compared them to these students' test scores.

"How much time a person sleeps the night. before an exam doesn't affect that person's grade," Grossman says. "A student who sleeps 7 hours every night will do better than a student who sleeps 7.5 hours one night and 6.5 hours another night."

"It's important for people to know that if their Fitbits tell them that they have terrible sleep, that may not actually be so," Michael Scullin, a sleep scientist at Baylor University says. Grossman also raises this point. Fitbit, Inc. makes this advanced tool. But it doesn't share how its tool works. This leaves a question about whether the tool is really correct when checking a student's sleep. Even so, Scullin emphasizes that there are enough data supporting ties between sleep and how well someone performs.

"Students need more sleep and less late evening use of phones and other screens. Even with after-school activities and schoolwork, they need to get enough sleep," Grossman says.
