For Zack, the shave was more than just a way to fund lifesaving research. It was a way to honor his late brother, Taylor Frink.

    Taylor, a volunteer firefighter in North Carolina, was killed in a car accident last September. Before his passing, Taylor was an eager supporter of St. Baldrick's. He went bald（秃头）for the cause in 2015, supporting kids with cancer and raising money to find cures.

    As a local hero, Taylor was beloved by the community. When he died, more than 1, 000 people attended his funeral to pay their respects. Zack looked up to his brother and this was the reason why he decided to become a junior firefighter himself. They did everything together. Zack remembers.

    Zack knew his brother had planned to shave again in 2016, so without hesitation he decided to fill his shoes and registered to shave at the local St. Baldrick's event in Kinston, N. C.

    “He was always goodhearted, and I want to make my brother proud,” shares Zack.

    As part of Zack's kindnesses, he raised more than $ 1,000 for the St. Baldrick's Foundation primarily by selling T-shirts he designed. Leading up to the event, Zack also visited his city council, commissioner's office and challenged the local official department to get involved.

    “We are not going to let Taylor's name be forgotten. That is what I love about St Baldrick's,” says Jean Culbreth, volunteer event organizer. “Zack gets it. He gets that what he is doing is keeping his brother's name alive.”

    The day finally came and Zack took his seat under the clippers (剪具), not only to honor his brother but to help kids with cancer. It was a special moment for all, and by the end of the day the event had raised more than $ 22,000!

    Compassion（同情）is a desire within us to help others. With effort, we can translate compassion into action. An experience last weekend showed me this is true. I work part-time in supermarket across from a building for the elderly. These old people are our main customers, and it's not hard to lose patience over their slowness. But last Sunday, one aged gentleman appeared to teach me a valuable lesson. This untidy man walked up to my register（收款机）with a box of biscuits. He said he was out of cash, had just moved into his room, and had nothing in his cupboards. He asked if we could let him have the food on trust. He promised to repay me the next day.

    I couldn't help staring at him. I wondered what kind of person he had been ten or twenty years before, and what he would be like if fortune had gone his way. I had a hurt in my heart for this kind of human soul, all alone in the world. I told him that I was sorry, but store rules didn't allow me to do so. I felt stupid and unkind saying this, but I valued my job.

    Just then, another man, standing behind the first, spoke up. If anything, he looked more pitiable, “Charge it to me,” was all he said.

    What I had been feeling was pity. Pity is soft and safe and easy. Compassion, on the other hand, is caring in action. I thanked the second man but told him that was not allowed either. Then I reached into my pocket and paid for the biscuits myself. I reached into my pocket because these two men had reached into my heart and taught me compassion.

    For many students who desire to move around but not far freely, one of the most common vehicles is the bicycle. For such a seemingly simple invention, its story is not that simple.

    Most historians trace its origin back to 1817, when a German nobleman named Karl von Drais invented a wooden, two­wheeled machine that riders moved forward with their feet. His invention became popular in both England and France, where it eventually became known as the velocipede. Unfortunately, it was eventually banned as a danger to pedestrians and was rarely seen after the early 1820s.

    Things were quiet for several decades until the bicycle development took off in the 1860s. An important milestone happened in Paris in 1863 when pedals were added to the front axle (轴). This occurred in Pierre Michaux's workshop, but it's unclear whether he or his employee, Pierre Lallement, should be given credit for the innovation Lallement moved to the United States, where he obtained a patent for "improvements in velocipedes" in 1866. These new machines proved to be popular, and the name "bicycle" had come into use by 1869. However, many people referred to them as "bone shakers", which described their clunky ride due to a heavy wooden frame and steel wheels.

    In the 1870s, "high wheelers" or "penny­farthings" became popular. However, with a large front wheel and a much smaller rear wheel, they could be dangerous, if riders had to stop suddenly, as they would "take a header" when their momentum (动量) carried them over the front wheel onto their heads. Eventually, English inventor John Kemp Starley designed a "safety bicycle" with two same small wheels, a chain drive, and a set of gears. With tires added in and brake systems bettered in the following decades, bicycle production had skyrocketed to over one million bicycles by 1899.

    Mass production of bicycles increased their popularity greatly, since they became affordable for the average person. Over the course of the 20th century, manufacturers continued to improve the features and design of bicycles as new technologies appeared.

    A layover or flight delay can be extremely fun in these international airports.

    Munich Airport, Germany

    Aviation lovers passing through Munich can take a behind the-scenes tour to learn how the airport operates. Visitors can also tour three historic aircraft and a retired rescue helicopter, climb up to a 28-metre high observation platform for an up-close view of take-offs and landings, and watch films on aviation in the airport's 60-seat cinema. Travelers can also kill layover time at an 18-hole mini-golf course, or even stop in for a teeth cleaning at the airport dental office.

    Changi Airport, Singapore

    After a long flight to Singapore, travelers can relax in a Balinese-style swimming pool, work out at the airport gym, or enjoy a drink and live musical performances at the airport's Music Bar. The airport also boasts a tranquil butterfly garden, and a "fragrant garden" which is home to 15 species of plants and trees. Free movies at one of two airport cinemas also keep passengers entertained.

    Schiphol Amsterdam Airport, the Netherlands

    Schiphol is Europe's fifth-largest airport. Here passengers can view the works of Dutch masters free of charge, and try their luck at airports casino (赌场). You can even have your wedding ceremony at Schiphol—couples can choose from four different wedding packages, including a 1930-style ceremony held on a Dakota military aircraft.

    San Francisco International Airport, California

    The airport's 24-hour Air Train not only moves passengers between terminal, but also provides a fun view of the runways. There are three aquariums to explore, along with interactive play areas, an aviation museum, and a library. If that's, not enough to keep the little ones busy, travelers can rent portable DVD players and movies for use in the airport.

    There were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Malaysia. I was moved.

    I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not particularly(特别) relish the long train journey and had brought along many magazines to read and reread. I looked about the train. There was not one familiar face. I sighed and sat down to read my Economics.

    It was not long before the train was across the Causeway and in Malaysia. Johor Bahru was just a city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive, I decided to wave back.

    From then on, my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.

    The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all round me. They all looked beautiful. When my uncle arrived with a smile, I threw my arms around him to give him a warm hug. I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car.

    I looked forward to the return journey.
