    As I walked along the Edgware Road, I felt as though the world was closing in on me. All the sounds I take for granted, had gone. I had entered a world of silence. This unsettling experience occurred a few weeks ago when I agreed to go deaf for the day to support the work of the charity Hearing Dogs for Deaf People, for which I am an ambassador.

    When I managed to take a cab to the office of my manager, Gavin, I couldn't hear what the taxi driver was saying to me. Conversation was impossible. Then, when I reached the office, I had to ring the intercom five times as I couldn't hear a response.

    Everybody said I was shouting at them—I simply wasn't aware of how loudly I was speaking as I couldn't hear my own voice. Gavin kept telling me my phone was ringing, but I didn't realize. I was too busy trying to concentrate on reading his lips. And when he tried to tell me a code to put into my phone, I had to keep asking him to repeat it, more slowly. Eventually he lost his patience and snapped at me: “Just give me the phone!” I was shocked.

    People couldn't be bothered to repeat themselves, so they kept trying to do things for me that I was perfectly capable of doing myself. I felt I'd lost control.

    Being deaf for the day was extraordinarily tiring. I had to work so hard to “listen” with my eyes, get people's attention and use my other senses to make up for my lack of hearing. It was a huge, exhausting effort.

    Until that experience I didn't realize how much I took my own hearing for granted, or the sorts of emotions and experiences deaf people go through. If a deaf person asks you to repeat something, never think: “It doesn't matter.” It does matter.

    If you think American cooking means opening a package and throwing the contents into the microwave oven (微波炉)，think again. On the one hand, it's true that many Americans have cold cereal for breakfast, sandwiches for lunch and instant (方便的) dinners. From busy homemakers to working people, many Americans enjoy the convenience (方便) of fast food that can be ready to serve in 10 minutes or less. On the other hand, many Americans realize the importance of cooking skills. Parents—especially mothers'—see the importance of training their children- especially daughter's. Most Americans think that there's nothing better than a good home-cooked meal. But with cooking, as with any other skill, good results don't happen by accident.

    Probably every cook has his or her own way of cooking. But there are some basic skills that most people follow. For example, baking is a main method (方法) of preparing food in America. For that reason, Americans would find it next to impossible to live without an oven. American cooks pay special attention to the balance of foods, too. In planning a big meal they try to include meat, a few vegetables, some bread and often a dessert. They also like to make sure the meal is colorful. Having several different colors of food on the plate usually makes for a healthy meal.

    For those who need guidance in their cooking, or for those who have just run out of ideas, recipes are a great help. Recipes list all the ingredients for a dish (generally in the order used), the amount of each to use, and a description of how to put them together.

    Modern festival-goers who worry about ending up with a dead mobile phone battery after days stuck in a muddy field with no electric plug power points may now have a solution—power boots.

    Mobile phone company European Telco Orange has introduced a phone charging prototype(原型)— a set of thermoelectric gumboots or Wellington boots with a “power generating sole” that changes heat from the wearer's feet into electrical power to charge battery-powered hand-helds.

    The boot was designed by Dave Pain, managing director at GotWind, a renewable energy company. Pain said the boot uses the Seebeck effect, in which a circuit made of two dissimilar metals conducts electricity if the two places where they connect are held at different temperatures. “In the sole（鞋底）of the Wellington boot there's a thermocouple and if you apply heat to one side of the thermocouple and cold to the other side it produces an electrical charge,” Pain said. “That electrical charge we then pass through to a battery which you'll find in the heel of the boot for storage of the electrical power for later use to charge your mobile phone.” These thermocouples are connected electrically, forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers(薄片). When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is made.

    But the prototype boot does have one shortcoming. You have to walk for 12 hours in the boots to make one hour's worth of charge.

    A man, who sometimes takes my bus, is in rags. His life seems different from that of the others. He looks exhausted and carries nothing. He appears along a downtown street, seemingly out of nowhere. We sometimes want to know where he sleeps at night.

    A few weeks ago he boarded the bus. A few stops later, a young woman boarded. She swiped (刷) her bus-card, only to find the machine would not accept it. The driver told her to pay the $2.25 fare. “I just bought this card,” she said. “I paid the money...”

    The driver said she could take the card back to the sales office and explain the problem. In the meantime she would have to pay the fare for that day. The woman became confused and distressed. The rest of us just watched, wondering how the problem would be solved. Suddenly the man rose from his seat, dropped a few coins into the fare box.

    “You're lucky,” the bus driver said quietly. “He paid for you.” Silence fell over the bus. The rest of us had watched the woman's discomfort, but he felt it. We lawyers, journalists and business people headed downtown to help fix the world. He fixed her world.

    I haven't seen him since that day. Some people believe angels occasionally drop down and move among us. All I know is that I have a new respect for the simple act of kindness. It speeds us along on our way.

Londoners are great readers. They buy vast numbers of newspapers and magazines and of books — especially paperbacks, which are still comparatively cheap in spite of ever-increasing rises in the costs of printing. They still continue to buy "proper" books, too, printed on good paper and bound（装订）between hard covers.

    There are many streets in London containing shops which specialize in book-selling. Perhaps the best known of these is Charring Cross Road in the very heart of London. Here bookshops of all sorts and sizes are to be found, from the celebrated one which boasts of being "the biggest bookshop in the world" to the tiny, dusty little places which seem to have been left over from Dickens' time. Some of these shops stock, or will obtain, any kind of book, but many of them specialize in second-hand books, in art books, in foreign books, in books on philosophy, politics or any other of the countless subjects about which books may be written. One shop in this area specializes only in books about ballet!

    Although it may be the most convenient place for Londoners to buy books, Charring Cross Road is not the cheapest. For the really cheap second-hand books, the collector must venture off the beaten track, to Farringdon Road, for example, in the East Central district of London. Here there is nothing so impressive as bookshops. The booksellers come along each morning and pour out their sacks of books onto small hand carts. And the collectors, some professionals and some amateurs, have been waiting for them. In places like this they can still, occasionally, pick up for a few pence an old one that may be worth many pounds.
