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.

    Fix it on your own

    Did you know that a bowl of rice could save your iPod if you drop it in a swimming pool by accident? Or that the camera on your phone could tell you what's wrong with your TV remote control(遥控器)? The experts at Geek Squad have made a gadget (小机件) rescue guide. So, let's take a look at some of their useful advice.

    How to get more juice out of your phone battery (电池)

    If your battery goes dead but you need to get a number or send one last text, try warming it up. That may give you a tiny bit of power. Take the battery from the phone and rub it between your hands. Or warm it under your arm for a few minutes. Then try to start the phone-but use it quickly.

    What to do if your gadget gets wet

    First, try drying it out with a vacuum cleaner(真空吸尘器). If a vacuum cleaner isn't at hand, fill a pot or bowl with uncooked rice and put your wet gadget inside. The dry, uncooked rice will absorb all the water and, after a few hours, you should be able to use the gadget. Don't forget to remove the battery and SIM card before you dry it.

    What to do if your TV remote control stops working

    If replacing the batteries doesn't work, get the camera function up on your phone and point the remote at the lens (镜头). When you press a button on the remote, if it is working, the glass bobble (小球) at the front of the remote will light up when you look at it on the screen of your phone. This is because the screen on a phone or digital camera picks up infrared rays (红外线), even though your eyes don't. If the glass bobble doesn't light up, the remote is broken. If it does, the receiving device is broken.

    A new report says living in a city makes it harder for people to concentrate(集中) on some tasks. The research found that people who live in rural areas can focus better than people in urban areas. The study is from Goldsmiths College, which is part of the University of London. Head researcher Dr. Karina Linnell and her team made great contributions. They studied how two groups of people did the same "thinking tasks". The team went to a remote(偏远的) part of Namibia, southwest Africa, to study the Himba tribe. Himba people live a very basic life in the desert. They are still doing traditional farming. The team also studied members of the same tribe who had moved to the nearest town. Dr. Linnell said the tribe who lived in the desert did much better on the tests than those in the town. It's really interesting and shocking.

    Dr. Linnell said their research may lead to changes in the way companies operate. In the future, workers may move from cities to live and work in the countryside. Linnell said there are too many things around us in the city that stop us from thinking about one thing for a long time. This means we do not work at our best. She asked, "What if, for example, companies realized certain tasks would be better carried out by employees based outside of the urban environment? There their concentration ability is better. "The past century has seen billions of people move from the countryside to big cities. In the future, the trend may not continue. If Dr. Linnell's research is true, this century might see many of those people return to the great outdoors. Let's wait to see what will happen.

    30 November 2017,Serbian tennis player Novak Djokovic defeated Scottish Andy Murray 6-1,7-5,7-6 in the Australian Open 2017 final to win the Grand Slam event (大满贯)for the sixth time. Murray has lost five Australian Open finals, facing Djokovic in all but one of them.

    Djokovic dominated the first set, winning 6-1 in just half an hour. He served seven aces (得分的发球)in total in the match. Murray fought back in the second set, which went up to twelve games lasting for 80 minutes. It was the longest set and Murray had nine aces, twelve in total for the match. Djokovic had 41 unforced errors, compared to Murray's 65.

    The third set lasted for 63 minutes and at 6-6 it went to a tie breaker, which Djokovic won 7-3, to win the eleventh Grand Slam title of his career.

    Djokovic has now equalled the record of Roy Emerson winning six Australian Opens. Djokovic after the match said,“Andy, you are a great champion and friend. I'm sure you'll have more opportunities to fight for this trophy”.Murray congratulated Djokovic, saying “I feel like I've been here before. Congratulations, Novak. Six Australian Opens is an incredible feat (业绩).The last year has been incredible. Good job.” He also left a message for his wife Kim Sears,“I'll be on the next flight home.” The couple is expecting a baby.

    Yesterday, Jamie Murray, Andy Murray's elder brother, won the Australian Open Men's doubles with Bruno Soares. Andy Murray was there in the audience, recording his brother's speech, to which Jamie said,“Andy, you should be in bed!”

    Grey clouds move as low as smoke over the treetops at Lolo Pass. The ground is white. The day is June 10. It has been snowing for the past four days in the Bitterroot Mountains. Wayne Fairchild is getting worried about our trek over the Lolo Trail—95 miles from Lolo Montana to Weippe in Idaho, across the roughest country in the West. Lewis and Clark were nearly defeated 200 years ago by snowstorms on the Lolo. Today Fairchild is nervously checking the weather reports. He has agreed to take me across the toughest, middle section of the trail.

    When Lewis climbed on top of Lemhi Pass, 140 miles south of Missoula, on August 12, 1805, he was astonished by what was in front of him; "high mountain chains still to the West of us with their tops partially covered with snow." Nobody in what was then the US knew the Rocky Mountains existed, with peaks twice as high as anything in the Appalachians back East.

    Today their pathway through those mountains holds more attraction than any other ground over which they traveled, for its raw wilderness is an evidence to the character of two cultures: the explorers who braved its hardships and the Native Americans who prize and conserve the path as a sacred (神圣的) gift. It remains today the same condition as when Lewis and Clark walked it.

    The Lolo is passable only from July to mid-September. Our luck is holding with the weather, although the snow keeps getting deeper. As we climb to Indian Post Office, the highest point on the trail at 7, 033 ft, we have covered 13 miles in soft snow, and we hardly have enough energy to make dinner. After a meal of chicken, I sit on a rock on top of the ridge (山脊). There is no light visible in any direction, not even another campfire. For four days we do not see another human being. We are occupied with the things that mix fear with joy. In our imagination we have finally caught up with Lewis and Clark.
