In today's world, English is the most wildly used language. It is our duty to learn English in the new situation of the reform and opening to the outside world. How can we master the English language? I'd like to give you some good advice.

    First, get interested in it. I enjoy listening to foreign friends talking when I was a child. At the same time I watched the English program Follow Me on TV. From then on, I kept on learning English. The more I learned, the more progress I made.

    Second, practice makes perfect. Many people study English very hard, but they are very shy to speak it in public, for they are afraid of making mistakes. Remember you have to make a mistake before you can correct it. A native English speaker makes mistakes sometimes, too.

    Third, the beginners should be encouraged to pay attention to idioms. The English language has many idioms. For example, you should say “ He is as strong as a cow.”

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

    Food production

With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that—it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to" re-create forms and pieces" of food that are" exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability(可持续性)

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids( 水解胶体)from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原 料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing，the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste( 糊状物)before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are doubtful about food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

    Eudaimonia is an Ancient Greek word, particularly stressed by the philosophers Plato and Aristotle, which deserves far more attention than it has because it corrects the shortfalls (缺失）in one of the most central, but troubling words in our modem language: happiness.

    When we nowadays try to clearly express the purpose of our lives, it is the word “happiness” that we commonly turn to. We tell ourselves and others that the most important principle for our jobs, our relationships and the conduct of our day-to-day lives is the pursuit of happiness. It sounds like an innocent enough idea, but too much reliance on the term means that we frequently unfairly tend to quit or, at least, heavily question a great many challenging but worthwhile situations. The Ancient Greeks did not believe that the purpose of life was to be happy; they proposed that it was to achieve Eudaimonia, a word which has been best translated as “fulfilment”.

    What distinguishes happiness from fulfilment is pain. It is very possible to be fulfilled and—at the same time—under pressure, suffering physically or mentally, overburdened and, quite frequently, in an irritable (易怒的）mood. This is a slight psychological difference that is hard for the word “happiness” to capture, for it's tricky to speak of being happy yet unhappy, or happy yet suffering. However, such a combination is readily accommodated within the respected and noble-sounding idea of Eudaimonia.

    The word encourages us to trust that many of life's most worthwhile projects will sometimes be in conflict with contentment, and yet will be worth pursuing. Properly exploring our professional talents, managing a household, keeping a relationship going, creating a new business venture or engaging in politics… none of these goals are likely to leave us cheerful and grinning on a daily basis. They will, in fact, involve us in all manner of challenges that will deeply exhaust and weaken us, provoke (激怒）and wound us. And yet we will perhaps, at the end of our lives, still feel that the tasks were worth undertaking. Through them, we'll have achieved something deeper and more interesting than happiness.

    With the word Eudaimonia in mind, we can stop imagining that we are aiming for a pain-free existence—and then blaming ourselves unfairly for being in a bad mood. We'll know that we are trying to do something far more important than smile all the time: we're striving to do justice to our full human potential.

    It is irrefutable: Parents, who talk to, read and engage with their very young children as often as possible, help them build literacy (读写能力) skills at an early age.

    Also certain: Parents of very young children usually have to do a lot of laundry. And low-income families tend to bring their kids with them to public laundromats (洗衣房).

    Those truths appear once a week at select neighborhood laundromats in Chicago. That's when librarians lay down colorful mats and oversized board books beside the industrial washing machines.

    Inside one of about 14 laundromats in the city's low-income neighborhoods, the librarians gather all available children for Laundromats Story Time (LST), a Chicago Public Library (CPL) program.

    With the noise of the washers and dryers, anywhere between a handful to more than a dozen children hear stories, sing songs and play games designed to help their brains develop. The event also aims to instruct parents on how to repeat the experience for their kids, working to raise poor literacy rates in underserved communities.

    "We read books, we sing songs, we do plays," says Becca Ruidl, the CPL's STEAM Team early learning manager, who runs the LST program. "We kind of keep it going so parents can walk in adn join in at any time. But a big part of what we do is model literacy skills for parents so they can do it at home with their kids."

    While a laundromat seems an unlikely place to engage with children, "we really wanted to meet people in the community where they're. "Ruidl says.

    And it clearly meets a need: Library officials say the program is in increasing demand, while Ruidl says families have adjusted their household's laundry day to suit the librarians' laundromat visits. At the same time, LST's co-sponsors—including a laundry industry trade group and Libraries Without Borders, an organization fighting poverty through literacy—have worked with the CPL to draft an instruction handbook to help expand the concept to other U.S. cities.

    Food festivals are a common occurrence in the UK and take place in all sorts of places and at all sorts of times. Whatever your taste, there's a food festival to match -no matter how specialized.

    Meatopia

    This three-day, London-based festival takes place at the end of August and is a meat lover's paradise. In addition to a range of meat products, from burgers to steaks, attendees can listen to live music, watch butchery shows, and attend informal meat-based workshops.

    Vegfest

    If you prefer a festival that will help you meet your five a day, then Vegfest fest is for you. This vegan-friendly event takes place several times a year. Here you can enjoy a wide selection of freshly prepared vegetables, learn cooking tips and hear talks on nutrition to help you make the most of your plant-based search.

    The Marmalade Festival

    Held in Cumbria, this festival has been running for 13 years. It includes a competition to find the best homemade marmalade. There are thousands of entries from over 30 different countries across the globe.

    The Ginger (姜) and spice Festival

    The Ginger and spice Festival, held in Market Drayton, celebrates its town's historic connection to Robert Clive, who returned from India with ginger. Because of this, they specialize in baking gingerbread, but also sell a range of spices from mild to hot.

    The National Honey show

    It started in 1921 and is the largest event of its kind. This three-day event attracts over 2000 participants to their traditional competition and offers lectures and workshops on beekeeping and, of course, that syrupy golden honey.

    While people's tastes are different from each other, the UK has something to offer most people. From large-scale festivities, to the smaller gatherings, one thing is certain: people are passionate about their food. And while some of the products on offer might be strange to someone, when food is given that much attention, it's unlikely to leave a bad taste in anyone's mouth.

    Yesterday I cleared up my house and I mean really cleared up my house. The room that gave the most results was my husband's "office". There I found: one right-footed shoe, size 10 (he lost the other one somewhere), a set of Star Wars videos and two small china cats someone gave me last birthday. I collected these "finds" and took them downstairs and logged (登录）on to eBay: the answer to all our rubbish.

    What is eBay? It aims to provide a global trading platform where almost anyone can trade almost anything. The idea came from Pierre Omidyar. Born in Paris, Omidyar moved to Washington when he was still a child. At High School he became very interested in computer programming and after graduating from Tufts University in 1988, he worked for the next few years as a computer engineer. In his free time he started eBay as a kind of hobby, originally offering the service free by word of mouth. By 1996 there was so much traffic on the site that he had to upgrade and he began collecting fees. Joined by a friend, Peter Skoll and in 1998 by his dynamic CEO, Meg Whitman, he has never looked back. Even in the great dot-com crashes of the late 1990s eBay went from strength to strength. It is now one of the ten most visited online shopping sites on the Internet.

    If you think about it, it's a perfect Internet idea. All you have to do is take an e-photo, write a description, fill out a sales form and you're in business; the world is your market place.

    Some of the more bizarre goods up for offer have been a piece of French bread, partially eaten by Justin Timberlake, advertising space on a man's head, and a pair of used false teeth.

    One week later I am proud of having a clean and tidy home and € 110 in cash. Someone even bought the shoe.
