I once had a friend who was diagnosed with terminal cancer, and the news that he might only live up to six months was a great shock to him, his family, and his friends. However, in spite of the serious illness, he was initially determined to look into all available treatments that might cure or extend his life. I think that when you find yourself in such situations, you tend to look up every possible way for hope of saving your life.

    As months went on and his health grew worse, I noticed an unexpected change in attitude that came over him. He had also been a happy person with a cheerful personality, but rather than give in to discouragement and self－pity, he took comfort in God and humanity. His talks focused on others rather than himself, and he spoke of the afterlife as something he was prepared for, believing that his concerned ancestors, including his mother and father, were there waiting for him.

    During the last few months, weeks, and days of his life, he was kindly cared for by family, friends, his loving wife, who looked after both his physical and emotional needs, and workers from a local hospice (安养院) came to the home to regulate his medication and provide any other needed support. He didn't complain about his fate, and he willingly allowed others to serve him.

    Indeed, one might think why God allows death and suffering in our world, but for me, such experiences taught me to value family more and kindness for others. You often can't learn these important attributes in the lap of luxury, and perhaps, such an experience is the greatest and final gift the illness can give those left behind.

    Shine United (Madison, Wisconsin)

    In the past five years, this Wisconsin-based advertising agency has shared more than $500,000 in profits with its employees through the company's ShineShares program. The agency partnered with the University of Wisconsin's oncology department to develop the Ride, a biking event that benefits cancer research. Employees also get snacks every day, “Beer Thirty” on Thursdays, and Summer Fridays, a program that lets employees leave at noon.

    GroundFloor Media (Denver, Colorado)

    The key for workers at this midsize public relations firm in Denver is that employees work anytime, anywhere. Headquarters are in a former warehouse downtown, near Coors Field. The offices are spread around the central space that doubles as a wet bar every Thursday when the company's “bear club” brings in a new brew.

    Ergodyne (St. Paul, Minnesota)

    The St. Paul-based company has grown to operating out of a retired storehouse with plenty of natural light. Rules about dressing? “Wear something.” Its purpose? To create cool, comfortable, and tough safety workwear for those who need it to get the job done. Ergodyne has around 50 employees, who enjoy hot-dish cook-offs, tickets to sporting events, and at least one happy hour every quarter.

    Southwest Michigan First (Kalamazoo, Michigan)

    It's family first at this Michigan economic development advising agency. CEO Ron Kitchens says that in the past year, the company has made a push to go green, initially started by the millennial employees who make up half the agency's workforce. A new staff position was created for the purpose of making sure every employee is able to balance working and cheering at their kids' sporting events or going fishing.

    As an oceanographer（海洋学家）, I've spent many years developing robots to explore the ocean, and now we're putting that technology to use in our JASON Project, a program that's designed to inspire students and get them interested in science, technology, engineering and mathematics. In theaters throughout the country, we bring kids together and send back to them on large screens our live explorations of large areas of the globe. Not only are the kids observers, but they can operate robots moving across the area while broadcasting images back to them. The kids have the sensation（感受） of really being at the site with us.

    I believe advances in robot technology will one day be the key to a new kind of travel. In the next 10 or 15 years, people will have rooms in their houses that will be able to simulate (模拟) other environment. I like to call this rooms “home domes” -- small theaters with screens and advanced equipment that can reproduce the sights, sounds, smells, and feel of a desert, or a forest. Hand in hand with these rooms, I can see a market for travel robots located in countries around the world. You could rent (租)a robot working in a rain forest, then go into your home dome, where you yourself operate the robot's movements. The equipment in the room will receive the sensations in the robot's environment and simulate them for you.

    Today, much of the world's population never travels more than 50 or 60 miles from home. And even a person with enough time can see only a part of the earth's sights. But this new way of travel will cost so much less in both time and money and allow people to see a lot more of the globe. And simulated travel will also help protect our planet. You can't take large groups of tourists to look at Dian Fossey's gorillas（大猩猩）. But a small robot, with no animal smell, can get very close to a gorilla and send the sights, sounds, and smells back to a million people.

    My father was attached to gardening by birth. One of my earliest memories is following Dad barefoot around in the garden with both hands blackened from digging in the soil. The garden was a wonderland full of possibilities.

    As Dad grew older, he still loved gardening. Even when he was diagnosed with cancer, he still planted all sorts of plants. Sometimes, I would come over to visit, and we would walk together in the garden. But then, something changed. Like the weeds that took over his garden, the cancer grew rapidly in Dad, and the doctor gave up. I stayed with Dad twenty-four hours a day and I found myself in all kinds of uncomfortable situations with Dad until I promised to care for the garden.

    Though I had heard the words of the doctor, what really made me believe that Dad was dying was the state of his garden. That year, he only planted tomatoes. Too tired to weed them, he simply tied them with strong strings to the fence and let them be. It made me sad to see them ignored, so I would come over and water them once in a while, and remove the weeds. I still remember the day I picked the last tomato from the vine(藤). That day was one of the saddest I had ever experienced in my life.

    Three years ago, I decided to plant my own garden. I decided I would start out with just a few tomatoes. That morning when I moved to the garden, something caught the corner of my eye and I had to smile. It was my eight-year-old son Nathan, standing barefoot in the soil, happily playing in soil.

    You may not have heard of it before, but solid rain (固体雨)has been helping Mexican farmers fight droughts(干旱) for over ten years. The magic solid rain looks like sugar and it can take in water up to 500 times as its own size and keep it in the ground for up to a year.

    The story of solid rain began in 1970, when American scientists developed a product used to take in water and help keep babies' bottoms dry. However, a Mexican chemical engineer saw this magic product as an opportunity to fight the drought. He developed a different kind of the product, which could be mixed with soil and slowly feed water to crops over a long period of time. His company, Solid Rain, has been quietly selling the product to Mexican farmers for over 10 years.

    Solid rain seems to be working wonders in Mexico. However, it has not come into use around the world. Well, that's mainly because a lot of people still don't know about it. The Mexican company has invested (投资) almost nothing into marketing, relying instead on word of mouth between Mexican farmers. However, recently, they have gotten requests from other dry countries like India and Australia.

    Solid rain has received the Ecology and Environment Award, but it has also received some negative views. Dr. Linda Scott says that the product is hardly new and that there is no scientific evidence that it can hold water for a year or last in the ground for ten years. Besides, solid rain can cause more harm than good in certain conditions.

    However, real-life use seems to show that solid rain is actually of great use to their farms. Frank Torres, a former green bean farmer used to rely on it even though drought wasn't such a big issue. He said that the production had increased by 50%.

Friends play an important part in our lives, and although we may take friendship for granted, we often don't clearly understand how to make friends. While we get on well with a number of people, we are usually friends with only a very few — for example, the average among students is about 6 per person. In all the cases of friendly relationships, two people like one another and enjoy being together, but beyond that, the degree of intimacy between them and the reasons for their shared interests vary greatly. As we get to know people, we take into account things like age, race, economic condition, social position, and intelligence. Although these factors are not of great importance, it is more difficult to get on with people when there is a marked difference in age and background.

Some friendly relationships can be kept on argument and discussion, but it is usual for close friends to have similar ideas and beliefs, the same opinions and interests — they often talk about "being on the same wavelength". It generally takes time to reach this point. And the more intimately involved people become, the more they depend on one another. People who want to be friends have to learn to put up with annoying habits and to stand differences.

In contrast with marriage, there are no friendship ceremonies to strengthen the association between two people. But the supporting and understanding of each other that results from shared experiences and emotions does seem to create a powerful bond, which can overcome differences in background, and break down barriers of age, class or race.
