Counting the number of miles traveled done by a product is a strange way of trying to tell the true situation of the environmental damage due to industry. Most food is transported around the world on container ships that are extremely energy efficient. It should be noticed that a ton of butter transported 25 miles in a truck to a farmers' market doesn't necessarily use less fuel on its journey than a similar product transported hundreds of miles by sea. Besides, the idea of “food miles” ignores the amount of fuel used in the production. It is possible to cut down your food miles by buying tomatoes grown in Britain rather than those grown in Ghana. The difference is that the British ones will have been raised in heated greenhouse and the Ghanaian ones in the open sun.

    What is the idea of “food miles” doesprovide, however, is the chance to cut out Third World countries from First World food markets. The number of miles traveled by our food should, as I see it, be regarded as a sign of the success of the global trade system, not a sign of damage to the environment.

    Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases with his students . The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems. His condition was not improving, and there was not much hope he would live.

    Dr. Mellinkoff asked to see the patient. He introduced himself in Spanish and, in a very gentle voice, asked how he felt. The patient smiled and said everything was all right. Then the doctor asked if he was able to eat. The patient said that he had no desire to eat.

    “ Are you getting food you like? ”

    The patient said nothing.

    “ Do you get the kind of food you have at home? ”

    The answer was no.

    The doctor put his hand on the man's shoulder and his voice was very soft.

    “If , you had food that you liked , would you eat it? ”

    “Yes , yes. ” the patient said.

    The change in the patient's appearance couldn't have been more obvious. Nothing was said, but it was easy to tell that a message had been sent and had also been received.

    Later, the doctor asked why the Guatemalan man wasn't getting food he could eat. One of the students said, “ We all know how difficult it is to get the kitchen to make special meals. ”

    “ Suppose, ” the doctor replied, “ you felt a certain medicine was absolutely necessary but that our hospital didn't carry it, would you accept defeat or would you insist the hospital meet your request? ”

    “ I would probably insist, ” the student said.

    “ Very well, ” the doctor said. “ You might want to try the same method in the kitchen. It won't be easy, but I can help you. Meanwhile, let's get some food inside this man as fast as possible, and stay with it. Or he'll be killed by hunger. By the way, there must be someone among you who can speak Spanish. If we want to make real progress, we need to be able to talk with him. ”

    Three weeks later, Dr. Mellinkoff told me that the Guatemalan man had left the hospital under his own power. It takes more than medicine to help sick people; you also have to talk to them and make them comfortable.

    The China Film Archive will also present a short lecture before each French movie on how to understand it.

    A machine that takes sweat-laden (浸满汗水的) clothes and turns the sweat into drinking water is in use in Sweden. The machine makes the clothes turn round quickly, heats them to remove the sweat, and then passes the steam through a kind of special material to make purified water.

    Since it has been brought into use, its creators say more than 1000 people have drunk others' “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.

    The device was built for the United Nations' child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.

    The machine was designed and built by the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine was a new water purification part developed by a company named HVR.

    “It uses a technique called membrane distillation (膜蒸馏),” he told the BBC. “We use a special kind of material that only lets steam through but keeps bacteria, salts, clothing fibers and other things out. They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person's T-shirt typically produces 10ml, about a mouthful.”

    The device has been put on show at the Gothia Cup-the world's largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-based advertising agency Deportivo, said the machine had helped raise awareness for UNICEF, but in reality had its limitations.

    “People haven't produced as much sweat as we hoped – right now the weather in Gothenburg is lousy,” Mattias Ronge said. “So we've equipped the machine with exercise bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater than the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”

    Thirteen-year-old American Jessica Goldstone wants to be a fashion designer when she finishes school. She thinks her designs would be more exciting than clothes bought from stores. But until this month, Jessica has never touched a sewing machine(缝纫机).

    After her first class, Jessica and six other girls aged 9 to 13 said that sewing was fun, cool and challenging.

    These students at Fabrics' Sew Fun class show that the sewing machine is becoming popular again.

    "There have been a lot of teens getting excited about sewing," said a sewing company worker Donna Smith. "Some of them come from the Project Runway TV show," she said. This TV show is an exciting weekly contest to make a great fashion designer. Every week one contestant (参赛者) fails the test and has to leave the contest.

    The number of people who joined sewing class summer camps grew by 10 percent this year. That's good news for companies that make sewing machines and publish sewing magazines. The Singer Sewing Company sold nearly 3 million sewing machines in the United States last year. This is about twice as many as in 1999.

    Sewing machines have been around for more than 150 years, but they have changed a lot since your grandmother was a girl.

    Spencer Carmel started sewing lessons after getting a sewing machine for her 11^th birthday. She has sewn a lot by hand, but she wants to make more difficult things. Spencer's class recently made hats.

    Another member of the class, Kelsey Oen, 9 years old, needed time to get used to her machine, but soon she could use it well. By the end of the class, Kelsey was happy and wearing her new hat.

    Sila Sutharat, a roasted chicken street vendor from Phetchaburi, Thailand, has come up with a unique way of cooking chicken. He uses 1, 000 mobile mirrors that concentrate sunlight into a strong beam(光束).

    Like most other street vendors, Sila used to cook his chicken over a charcoal(木炭)fire. But that all changed in 1997, when an ordinary observation gave him a great idea. One day, he was hit by the sunlight reflected off the window of a passing bus, and he felt its heat. "I could possibly change it into energy," Sila told himself. Then he started working on how to make use of the sunlight to cook his chicken.

    "They said that I'd gone mad, and that cooking chicken like this was impossible," Sila told reporters about how people reacted to his idea. But he didn't let their jokes get to him, and in the end he was the one who had the last laugh. He invented a panel featuring 1, 000 small mirrors that could be moved. It worked exactly as he predicted, allowing him to cook a 1.5 kg chicken in just 10 to 15 minutes. "After a long time passed by, they'd say: "Actually, you could do it," " Sila Sutharat recalls. Sila says that his invention can make the temperature go up to 312'C. This is why he always wears a special mask instead of a cook's hat when operating it.

    Sila's solar roaster is an unusual sight. It has attracted quite a few curious people who are eager to taste Sila's sun-cooked chicken. He's been using this cooking method for two decades now. And he says it's much better than traditional roasting methods. It is free, cooks all parts of the chicken, and best of all, it's 100% clean. Phetchaburi Rajabhat University thought Sila's idea was very good and useful, so they awarded him an honorary science degree.
