Conor Grennan was unwilling to be a volunteer(志愿者). The 29-year-old American was not sure if he had the skills or a strong feeling for it.However, he went to work at an orphanage(孤儿院) in Nepal. His first thought was to make people impressed.

    "I thought that if I volunteered just once. I could retell the story over and over," Grennan said in a Huffington Post article.However, his three-month stay it the orphanage turned into in unusual experience. It was 2004 and Grennan had given up his job to begin a year-long around-the-world trip, His first three months were spent in Nepal.

    When he arrived in the village, he knew nothing about the children or the local culture. When he opened the gate of the Little Princes Children's Home, he was faced by the excited children.

    The young American ended up caring for 18 children. He later discovered that they were trafficked(被拐卖的)children. So he walked through the mountains with great difficulty to find the kids' families, "I started walking with photos of the kids." he told the Reuters reporter. "I would show up in villages and show photographs around. I went with 24 photos, and I found 24 families." At the same time, he put his heart into Nepalese culture.

    Grennan said, “Volunteering is the single best way to see how the rest of the world lives.”

    He also encouraged others to do what he had done. He believes that volunteering needs only making decisions to show up.

    Grennan's fight against child-trafficking has changed him. His book, Little Prince, came out last week.

    In 1947 a group of famous people from the art world headed by an Austrian conductor decided to hold an international festival of music, dance and theatre in Edinburgh. The idea was to reunite Europe after the Second World War.

    At the same time, the Fringe appeared as a challenge to the official festival. Eight theatre groups turned up uninvited in 1947, in the belief that everyone should have the right to perform, and they did so in a public house disused for years.

    Soon, groups of students firstly from Edinburgh University, and later from the universities of Oxford and Cambridge, Durham and Birmingham were making the journey to the Scottish capital each summer to perform theatre by little-known writers of plays in small church halls to the people of Edinburgh.

    Today the Fringe, once less recognized, has far out grown the festival with around 1,500 performances of theatre, music and dance on every one of the 21 days it lasts. And yet as early as 1959, with only 19theatre groups performing, some said it was getting too big.

    A paid administrator was first employed only in 1971, and today there are eight administrators working all year round and the number rises to 150 during August itself. In2004 there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries. More than 1.25 million tickets were sold.

    We all know that exercise is good for your health. But some kinds of exercise may be better than others.

    Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer. Researchers say it is not important how far you run. It also does not matter how fast or even how often you run. As advertisements for the running shoes Nike say, “Just Do It.”

    Recently researchers studied more than 55,000 adults. About one-fourth of the adults reported running regularly. The study found these runners were considerably less likely than non-runners to die of any form of disease, including heart disease. In fact, the runners lived, on average, three years longer than the non-runners.

    This study lasted 15 years. During that time, more than 3,400 of the individuals died. About 1.200 of the deaths were linked to heart disease, hear, attack or stroke.

    One of the researchers is a man named D.C. Lee, a professor of Iowa State University Compared to non-runners, he said, runners showed a much lower risk of dying from some diseases. “Compared to non-runners, runners showed 30 percent lower risk of death by any causes, including heart attack, stroke and cancer. Also, runners compared to non-runners showed 45 percent lower risk of death by cardiovascular diseases（心血管疾病）, including heart attack and stroke.”

    D. C. Lee and the other researchers found that speed, distance and how often one runs made little difference in reducing the risk of death. The runners in the study averaged between 10 and 16 kilometers per hour. Mr Lee said slower runners and those who only ran once or twice a week were helped nearly as much as those who ran faster and further. “And also we looked at the inning over time and we found that persistent runners（over six years）showed the biggest benefits, as well.”

    It seems that in many places storms visit more often. When a storm is coming, most people leave the area as quickly as possible and head for safety. But there are a few people who will get into their cars and go straight for the center of the storm. These people are willing to risk being killed by floods or 100-kilometer-an-hour winds for the excitement of watching the storm close up.

    "Storm chasing" is becoming an increasingly popular hobby, especially in the Midwest of the United States, where there are frequent storms between March and July. A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to 1,000 kilometers to where the storm will be and waits for it to develop.

    Although anyone can do it, storm chasing is extremely dangerous. The power of a big storm can throw a cow into the air or destroy a whole house in seconds. Storm chasers are also often hurt in accidents caused by driving in a heavy rain. If you are a beginner, it is much safer to join a group for storm-chasing vacations during the storm season.

    Even then, storm chasing is not all adventure and excitement. "Storm chasing is 95% driving," says Daniel Lynch, who spends most of his summer storm-chasing. "Sometimes you can sit around for hours waiting for something to happen, and all you get is blue sky and a few light showers."

    However, for storm chasers, it is all worth it. "When you get close to a storm, it is the most exciting sight you will ever see in your life," says Jasper Morley. "Every storm is an example of the power of nature. It is the greatest show on Earth."

    Have you grasped the information taught by your teacher in class? Have you understood what you saw on the screen? Maybe everyone has their own learning style.

    Generally speaking, we gather information with our minds and bodies in different ways, such as seeing, hearing and doing. Then our brains deals with that information, organizing it and connecting it to things we are already aware .In other words, our brains will deal with the information in different ways. Sometimes we think in pictures or words. Sometimes we remember details or the big pictures.

    For different people, their learning styles are different too. One person may find it hard to make out the information in written forms but easy to know it immediately in an oral description. However, another person might find difficulties with the picture but the written message.

    Now scientists say there exist seven basic learning styles.

    Linguistic: These people learn through listening, reading, speaking and writing.

    Logical: These people learn with formula (公式) and principles (原理).

    Visual: These people learn by seeing what they are studying.

    Musical: These people learn well when information is presented through music.

    Kinesthetic: These people learn from movement and physical activities.

    Intrapersonal: These people learn best by linking new information directly with their own experiences.

    Interpersonal: These people learn well by working with others.

    Therefore, if you know what learning style is your strength, you can balance your weakness, and get a more successful learning experience.

Five trends to watch in the coming year

The number 21 is connected with luck, risk, taking chances and rolling the dice, all of which seem strangely appropriate for a year of unusual uncertainty. As 2021 approaches, here are some trends to watch in the year ahead.

⒈ Fights over vaccines

As the first vaccines become available in quantity, the focus will shit from the heroic effort of developing them to the equally difficult task of distributing them. Vaccine negotiations will accompany fights within and between countries over who should get them and when.

⒉ A mixed economic recovery

As economies bounce back from the pandemic, the recovery will be inconsistent, as local outbreaks and restrictions come and go — and governments turn from keeping companies on life-support to helping workers who have lost their jobs.

⒊ A less footloose world

Tourism will shrink and change shape, with more emphasis on domestic travel. Airlines, hotel chains and aircraft producers will struggle, as will universities that rely heavily on foreign students.

⒋ An opportunity on climate change

One positive side to the crisis is the chance to take action on climate change, as governments invest in green recovery plans to create jobs and cut emissions. How ambitious will countries' reduction promises be at the UN climate conference, delayed from 2020?

⒌ The year of déjà vu

That is just one example of how the coming year may feel, in many respects, like a second take on 2020, as events including the Olympics, the Dubai Expo and many other political, sporting and commercial gatherings do their best to open a year later than planned.
