Experiments under way in several labs aim to create beneficial types of genetically modified foods, including starchier potatoes and caffeine-free coffee beans. Genetic engineers are even trying to transfer genes from a cold-winter fish to make a frost-resistant tomato.

    A low-sugar GM strawberry now in the works might one day allow people with health problems such as diabetes (糖尿病) to enjoy the little delicious red fruits again. GM beans and grains rich in protein(蛋白质) might help people at risk of developing kwashiorkor. Kwashiorkor, a disease caused by severe lack of protein, is common in parts of the world where there are severe food shortages.

    Commenting on GM foods, Jonathon Jones, a British researcher, said: "The future benefits will be enormous（巨大的）, and the best is yet to come". To some people, GM foods are no different from unmodified foods. "A tomato is a tomato," said Brian Sansoni, an American food manufacturer.

    Critics of GM foods challenge Sansoni's opinion. They worry about the harm that GM crops might do to people, other animals, and plants.

    In a recent lab study conducted at Cornell University, scientists tested pollen(花粉) made by BT corn, which makes up one-fourth of the U.S. corn crop. The scientist dropped the pollen onto milkweed, a plant that is the only known food source of a butterfly caterpillar(毛虫). Within four days of feeding on the leaves, almost half of a test group of caterpillars died. "This is a warning bell." said Cornell researcher Linda Raynor.

    Some insects that are not killed by GM foods might find themselves made stronger. How so? The insecticides are used on the crops to kill the pests. But GM plants produce a continuous level of insecticide. Insects relying on those crops may develop resistance to the plants and they may also develop a resistance to the insecticide.

    At the forum on GM food held last year in Canada. GM crops that have been made resistant to the herbicide might crossbreed with wild plants, creating "superweeds" that could take over whole fields.

    So where do you stand? Should GM food be banned in the United States, as they are in parts of Europe? Or do their benefits outweigh（胜过） any of the risks they might carry?

    We've considered several ways of paying to cut in line: hiring line standers, buying tickets from scalpers (票贩子), or purchasing line-cutting privileges directly from, say, an airline or an amusement park. Each of these deals replaces the morals of the queue (waiting your turn) with the morals of the market (paying a price for faster service).

    Markets and queues—paying and waiting—are two different ways of allocating things, and each is appropriate to different activities. The morals of the queue, “First come, first served, have an egalitarian (平等主义的) appeal. They tell us to ignore privilege, power, and deep pockets.

    The principle seems right on playgrounds and at bus stops. But the morals of the queue do not govern all occasions. If I put my house up for sale, I have no duty to accept the first offer that comes along, simply because it's the first. Selling my house and waiting for a bus are different activities, properly governed by different standards.

    Sometimes standards change, and it is unclear which principle should apply. Think of the recorded message you hear, played over and over, as you wait on hold when calling your bank: “Your call will be answered in the order in which it was received.” This is essential for the morals of the queue. It's as if the company is trying to ease our impatience with fairness.

    But don't take the recorded message too seriously. Today, some people's calls are answered faster than others. Call center technology enables companies to “score” incoming calls and to give faster service to those that come from rich places. You might call this telephonic queue jumping.

    Of course, markets and queues are not the only ways of allocating things. Some goods we distribute by merit, others by need, still others by chance. However, the tendency of markets to replace queues, and other non-market ways of allocating goods is so common in modern life that we scarcely notice it anymore. It is striking that most of the paid queue-jumping schemes we've considered—at airports and amusement parks, in call centers, doctors' offices, and national parks—are recent developments, scarcely imaginable three decades ago. The disappearance of the queues in these places may seem an unusual concern, but these are not the only places that markets have entered.

    William Purkey, a well-known professor of education, said, “Dance like no one is watching, love you'll never be hurt, sing like no one is listening, and live like it's heaven on earh.” It seems like the perfect life philosophy — and one I've learned to apply to running over the year.

    But I didn't always feel this way. In my early days, when I weighed 240 pounds, I ran like everyone was watching — and judging. If I was on a run and saw a car approaching, I'd stop and pretend I was looking for something I'd lost. I bought the high-tech gear and clothes that I thought would make people believe I was a runner. And I didn't have a clue if the expensive shoes I was wearing were the right kind for me — I just wanted to look like I fit in with this group.

    To be honest, I felt a certain satisfaction in believing that someone was watching. I really thought that other people cared about my performance. The best example of this was a combined, two-lap marathon in Florence, Italy. As I approached the finishing line, the crowd began to cheer. I was surprised. Here I was, thousands of miles from home, and the Italians were shouting for “IIPenguino.”

    About 20 yards from the finishing, the truth set in when the winner of the full marathon went past me as I was finishing the half-marathon. No one was cheering for me. No one probably even noticed that I was finishing. I couldn't help but smile at my own illusion of self-importance.

    That's when I realized I had been running for every reason except the right one. I ran to make other people happy, ran to live up to their expectations. But no one was watching — no one cared. So I decided I was going to run for me—just me—and gained a new enjoyment from the sport I hadn't truly experienced yet. I've learned to run like no one is watching.

    So if you see me at race, and I look like a 60-year-old guy waddling(蹒跚) along, don't worry. I'm fine. The miracle isn't that I finished. The miracle is that I had the courage to start.

    Chinese people are, quite rightly, proud of their food. However, when foreigners like Britons and Americans think of Chinese food, their impression of it is different to what you might think.

    Growing up in the UK, the Chinese food I was used to eating was food I now recognize as being from Guangdong. For example, a typical dish I would order would be pork in sweet and sour sauce, probably with some rice and spring rolls on the side. This is the type of food we generally eat because most Chinese immigrants(移民) to the UK have come from Guangdong. You can tell, because when most British people try to copy the sound of Chinese, they actually copy the sound of Guangdong people—hearing the real Putonghua is sometimes a shock to British people who have grown up thinking it sounds completely different!

    British attitudes to Chinese food may be changing, though. Chinese-American chef Ken Hom has been on British TV for 30 years, and he told BBC Food: "Chinese food at the beginning of the 80s (in the UK) was sweet and sour pork, mainly. Most Brits had the unchangeable view of Chinese food… Now you are seeing more local Chinese food from Sichuan, Hunan and other areas of China. It is no longer just Guangdong food." Similarly, to most Americans, Chinese food doesn't go too far past orange chicken and fortune cookies, but more Chinese local dishes are becoming successful, especially in big cities like New York.

    Attitudes have not quite changed completely, though. Many foreigners who live in China will be familiar with this question from a relative back at home: "Have they given you dog yet?" Yes, perhaps because people still know too little about Chinese culture, many people believe that Chinese people love to eat dog meat. And of course, some people do eat dogs, which to Americans is like "eating a member of one's family" according to Vision Times. Also, Chinese people eat many other things people in the West do not—chicken claws, duck heads and some animals' organs.

    But what do foreigners think when they come to China and taste real Chinese food? You'll be glad to know that in my experience, the impressions have been very good.

    Driverless technology will soon enter another major global industry: shipping. Several companies recently announced plans to start self-sailing ships to improve safety and efficiency（效率）.

    One of them is Norwegian chemical company Yara International. Yara has designed to build an autonomous ship expected to start next year. The ship is fully electric to reduce air pollution. It is designed to carry containers normally transported by truck. This means the ship will also improve road safety by replacing about 40,000 truck trips a year.

    Yara plans to operate the ships by remote control beginning sometime next year. By 2020, the ships should be loading and sailing themselves. Another company focusing on self-sailing ships is the world's largest mining company, Australia's BHP Billiton. The company's Vice President of Freight, Rashpal Bhatti, recently spoke about the technology. He said, “I believe automation（自动化）will be one of the biggest changes for shipping in the future.” Autonomous ships offer important chances to improve safety and provide better efficiency results to the marine supply chain. He added that self-sailing ships could become a reality within the next decade.

    Rolls-Royce, the British automobile and engine manufacturer, is also developing unmanned shipping technologies. Oskar Levander is the company's head of marine operations. He told a conference last year, “This is happening. It's not if, it's when.” Several shipping companies have invested hundreds of millions of dollars to develop self-sailing ships expected to be used by 2025. These ships will be equipped with technology to collect weather and sea data. They will then use the data to plan out the safest, shortest and most fuel-efficient route.

    Last year my children gifted me a stainless steel (不锈钢的) coffee plunger (法式按压咖啡壶). I love to start the day with a strong black coffee and couldn't wait to use it. I looked forward to the following morning's coffee making, knowing that I probably wouldn't smash (打碎) this plunger as easily as I had done so often in the past.

    But as I poured my first cup of coffee, the plunger spilled (洒出) all over the table. Thankfully no one was around to see my disappointed face! I kept trying, but each morning would see me wiping up the coffee. Then I realized that if I poured very slowly there would be no spilling.

    This was at first a very painful experience. My normal practice was to rush through breakfast so that I could get on with my day.

    But in time I learned not only to pour slowly but to enjoy the experience: the smell, the taste, and the stillness of a new day.

    It prompted (促使) me to reflect upon whether there were other areas of my life I was rushing through. Most of life, it seemed.

    I started to leave extra time to do even the most ordinary tasks. When shop owners would apologize for keeping me waiting, I'd say, "Not a problem, I'm not in a hurry." Even hanging out washing became pleasurable when a couple of extra minutes of standing still and listening to the birds singing in the trees around me became part of my routine.

    Besides, one of my favorite experiences living in the inner city for many years was sitting on the front doorstep of our home spending time with strangers. We sat on the steps, each of us with a cup of coffee in our hands, listening to each other's stories. It was one of the warmest things about living in a busy city. It was as if the world around us slowed to a pace (步伐) we could both handle.

    Stillness and quietness not only slow the pace of life, but also feed the soul, helping us to enjoy the world's small pleasures.
