It was Mother's Day morning last year and I was doing my shopping at our local supermarket with my five-year-old son, Tenyson. As we were leaving, we found that only minutes earlier an elderly woman had fallen over at the entrance and had hit her head on the concrete. Her husband was with her, but there was blood everywhere and the woman was embarrassed and clearly in shock.

    Walking towards the scene, Tenyson became very upset about what had happened to the couple. He said to me, “Mum, it's not much fun falling over in front of everyone.”

    At the front of the supermarket a charity(慈善) group had set up a stand selling cooked sausages and flowers to raise funds. Tenyson suggested that we should buy the lady a flower. “It will make her feel better,” he said. I was amazed that he'd come up with such a sweet idea. So we went over to the flower seller and asked her if we could buy a flower for the lady to cheer her up. “Just take it,” she replied. “I can't take your money for such a wonderful gesture.”

    By now paramedics（救援人员）had arrived, and were attending the injured woman. As we walked up to her, my son became intimidated by all the blood and medical equipment. He said he was just too scared to go up to her. Instead I gave the flower to the woman's husband and told him, “ My son was very upset for your wife and wanted to give her this flower to make her feel better.”

    At that, the old man started crying and said, “Thank you so much, you have a wonderful son. Happy Mother's Day to you.”

    The man then bent down and gave his wife the flower, telling her who it was from. Though badly hurt and shaken, the old lady looked up at Tenyson with love in her eyes and gave him a little smile.

    One morning, my newspaper wasn't delivered on time. Since I always brought it to work, it upset me that I would have to pick one up on my way to work. After breakfast, I was already running late, but figured I could make it if I hurried.

    As I pulled into the parking lot of the store, I noticed a young man in a wheelchair who seemed to be struggling. “Someone else will stop and help him,” I thought.

    However, no one stopped. I got out, and walked over to see what the trouble was.

    “Is there anything I can do?” I asked. It was then that I noticed he wasn't able to speak, and was still struggling with the chair.

    I looked down at the chair and noticed that the clamps (夹具) holding the electronic keyboard had apparently become loose causing the equipment to slip down, out of his reach.

    I pulled it back into place and then re-tightened the clamps. He hit a key on the keyboard. An electronic voice told me, “Thank you.” He then found the control that steered (操纵) the chair, turned and left.

    I got back in my car and headed off to work, completely forgetting my newspaper. As I drove, I felt a deep gratitude (感激). I was truly blessed to have the physical abilities that allow me to live a normal life. Here was this young man who relied on machines to get around and communicate. He probably dreamed about doing all the things that I thought were normal and simple.

    It's funny; fifteen minutes before that happened, I was whining because my morning paper hadn't arrived on time. I was glad I helped the young man, because he helped me gain a new viewpoint on everything I had in my life.

    The Marches were a happy family, Poverty, hard work, and even the fact that Father March was away with the Union armies could not down the spirits of Meg, Jo, Beth, Amy, and Marmee, as the March girls called their mother.

    The March sisters tried to be good but had their share of faults. Pretty Meg was often displeased with the schoolchildren she taught; boyish Jo was easy to become angry; golden-haired schoolgirl Amy liked to show up; but Beth, who kept the house, was loving and gentle always.

    The happy days passed and darkness came when a telegram arrived for Mrs. March. “Your husband is very ill,” it said, “come at once.” The girl tried to be brave when their mother left for the front. They waited and prayed. Little Beth got scarlet fever (猩红热) when she was taking care of the sick neighbor. She became very ill but began to recover by the time Marmee was back. When Father came home from the front and at that joyful Christmas dinner they were once more all together.

    Three years later the March girls had grown into young womanhood. Meg became Mrs. Brooke, and after a few family troubles got used to her new state happily. Jo had found pleasure in her literary efforts. Amy had grown into a young lady with a talent for design and an even greater one for society. But Beth had never fully regained her health, and her family watched her with love and anxiety.

    Amy was asked to go and stay in Europe with a relative of the Marches'. Jo went to New York and became successful in her writing and had the satisfaction of seeing her work published there. But at home the bitterest blow was yet to fall Beth had known for some time that she couldn't live much longer to be with the family and in the spring time she died.

    News came from Europe that Amy and Laurie, the grandson of a wealthy neighbor, had planned to be married soon. Now Jo became ever more successful in her writing and got married to Professor Bhaer and soon afterwards founded a school for boys.

    And so the little women had grown up and lived happily with their children, enjoying the harvest of love and goodness that they had devoted all their lives to.

    Over the years, Brian Wansink, director of the Food and Brand Lab at Cornell University, has studied such things as how far Americans typically drive to buy food, how many times we refill our plates at all-you-can-eat buffets and how we organize our kitchens. In the mid-2000s he famously coined the phrase "mindless eating"(and wrote a book by that name) to focus attention on all the bad dietary decisions we make without really thinking about them.

    His new book, Slim by Design: Mindless Eating Solutions for Everyday Life, aims to change the design of restaurants, school lunchrooms, office cafeterias and homes so that the mindless choices we make will be more healthful ones. Some examples:

    Keep kitchen counters clear. No visible snack food, no bread, no nuts — not even breakfast cereal. In Wansink's research, "women who had even one box of breakfast cereal that was visible — anywhere in their kitchen — weighed 21 pounds more than their neighbor who didn't."

    Trick yourself into drinking less wine. "We tend to focus on the height of what we pour and not the width, so we pour 12 percent less wine into taller wineglasses than we pour into wider wineglasses." And the shape of the glass is not the only variable that affects how much we drink. Wansink writes: "Because red wine is easier to see than white wine, we pour 9 percent less red wine whenever we pour a glass."

    Wansink said his researchers also found that people ate less at restaurants when sat in well-lighted areas near windows and doors, than in darker areas or in the back. They ate less if they were offered a doggie bag, or to-go box, before they got their meals: apparently the idea of getting a "free" second meal outweighed the impulse (冲动) to clean their plates. Workers who frequently ate at their desks weighed 15.4 pounds less, on average, than those who didn't. Fruits and vegetables kept on the top shelf of the refrigerator were eaten at higher rates than those on lower shelves.

    The point, Wansink says, is to consider findings like those and change your environment or habits. Then you won't have to think about it: You'll just eat less.

Max Mathews has been called the father of computer music.He created electronic tools so that people could use computers as musical instruments.He had a great influence on the development of electronic music and how it is written,recorded and played.

In 1957,Mathews wrote the first computer program that enabled a computer to create sound.At that time,he was working as an engineer at Bell Laboratories in New Jersey.His computer program enabled a large IBM computer to play a 17 seconds piece of music that he had written.The computer was so slow that it would have taken an hour to play the piece of music in 17 seconds.For that reason,Mathews moved the work to a tape player,which could be sped up to play the music at a normal speed.He later said that the sound quality of the musical notes was not great,but the technical importance of the music was huge.

Mathews continued creating other versions of the music program.He became interested in how computers could help musicians outside recording studios.The Groove program he developed was the first computer program made for live performances.

He also developed an electronic device he called the Radio Baton.The device looks like two drum sticks.It enables the user to control the speed and sound levels of orchestral music playing on a computer.The user does this by moving the two sticks on a special electronic surface.

Mathews believed modern musicians are not making full use of the power of computer music.He said a violin always sounds like a violin.But with a computer,the way a violin sounds is unlimited.He said he didn't want computer sounds to replace live music.But he said he hoped laptop computers would one day be considered serious instruments.

"Pop" stands for popular, and a pop singer has to work very hard to stay popular. He must either give the public what they want, or he must find a new way of singing that will attract their attention. Even when he has succeeded, and his records are sold everywhere, he cannot relax. Then he must work harder than ever to remain popular, because there are always younger singers trying to become famous and to steal some of the popularity.

The life of a successful pop singer isn't easy at all. He can only relax when he is alone, because everything he does is watched and reported in the special newspaper written for the fans. The fans are the most important people in the world for the singer. They buy his records, they go to his concerts, and they make him rich and famous. But they can be very annoying, too. Sometimes their enthusiasm (热情) is so hysterical (歇斯底里的) that they do anything to get a souvenir (纪念品). They steal handkerchief, they tear off buttons, and they even cut off pieces of unfortunate singer's hair. Many singers have been forced to hide, and some who have not been so lucky as to escape have been stripped (剥) practically naked by their fans. A pop singer has to spend a lot of money on clothes because he must always look smart, or at any rate, different. He must have a luxurious (豪华的) car. And most importantly, he must always keep smiling for the benefit of his public.
