Speaking in public meetings is necessary for many students and employees. As well, it is a difficult task for them, especially for non-native speakers. A great many researchers have made efforts to help foreign language learners to improve the approaches.

    Charles LeBeau is a public speaking professor and consultant. Currently, he teaches at two universities and at the Toshiba International Training Center. He has also written books on the subject. English language learners around the world use his book Speaking of Speech.

    In Speaking of Speech Mr. LeBeau says a simple approach helps the learners. So, the professor divides public speaking into three parts: the physical message, the visual message, and the story message. He says, “The central thing to remember about public speaking or presentation is that it's a very complex communicative activity. For non-native speakers it's a really scary activity. So to make that more simplistic and easy for them, the approach that I've taken is to simplify and break it down. First if we look at presentation, what's going on? There are basically three messages that the presenter is giving the audience at the same time. There's what I call the physical message, namely body language. It's the way that my body, as a speaker, is talking to the audience. Then there's also the visual message. The visual messages are the slides that we now make and show the audience. The third message is the story message, which is the content of our presentation. The story message is the verbal message, what we say to the audience. The story message also includes how we organize our ideas to present to the audience.”

    He says the simple approach to breaking down the parts of public speaking has proved itself. He says learners improve quickly and do a good presentation after a few days of study.

    After years of research and testing, the hybrid car was developed and put on the market. It' s an interesting and exciting new improvement in today' s world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources.

    The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car' s engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.

    A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144-volt battery pack is actually recharged through the energy that is produced when the car's brakes are used. This is referred to as “regenerative braking”, because it generates electricity.

    Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.

    Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, “I am low on gas”. When it completely runs out, the warning reads, “YOU ARE NOW OUT OF GAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

    Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I've ever had: Be bold and brave — and mighty (强大的) forces will come to your aid.

    Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

    Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas — even physical strength greater than most of us realize.

    Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet（子弹） — and stopped him cold.”

    Boldness — a willingness to extend yourself to the extreme—is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

    So, always try to live a little bit beyond your abilities—and you'll find your abilities are greater than you ever dreamed.

    Alibaba started taking the lead in China by connecting big Chinese manufacturers（制造商）with big buyers across the world. Its business-to-business site, Alibaba.com allowed business to buy almost everything. Alibaba's advantage wasn't hard to judge: size. Alibaba is just big, even by Chinese standards. Its market attracts 231 million active buyers, 8 million sellers, 11.3 billion orders a year—and Alibaba is just the middleman. It encourages people to use its markets—not charging small sellers a percentage of the sale.

    If you want a quick look into the influence of Alibaba on daily Chinese life, take my experience. I moved to Beijing a year ago and quickly got tired of visiting small stores across the crowded, polluted city of 20 million people in search of new electronics, bathroom furnishings, and anything else my wife wanted. “You're looking for what exactly? Why not try it?” My Chinese teacher asked me one day. With that, my wonderful new relationship with Alibaba began.

    Alibaba's original business-to-business model now is second to consumer buying. Chinese retail（零售）buying makes up 80% of Alibaba's profit, and leading that group is Taobao, with 800 million items for sale and the most unbelievable selection of things you'll ever find. TMall.com is Alibaba's other big site, where you can find brand name goods from Nike and Unilever near the lowest prices.

    What I have a hard time explaining to friends and family back in the U.S.is how China has gone beyond traditional shopping—big-box retailers especially—in favor of online purchases on Taobao and a few other sites. In smaller towns than Beijing, where big retailers have not yet traveled, shopping online is shopping, and shopping is Taobao.

    I have a list of some of my recent purchases on Taobao for a sense of how wide the marketplace is. Almost everything arrived a day or two after ordering with free shipping. I'm not even a big buyer, because I need friends to help me search the Chinese-language site. When I was searching my purchase history on my Chinese teacher's iPad, which helps me buy goods, I looked through with great difficulty about 10 of her purchases for every one of mine.

    You can tell a lot about a country from its passport. Color is the first give-away. Nations tend to pick colors that reflect their national character. New Zealand decorates its famous rugby team, its airline and its passports in the nation's favorite color—black. Many Islamic countries have green passports because of the importance of the color in the Muslim faith.

    But as well as a statement of national identity, color can show international cooperation. The British passport was originally a navy blue. But after Britain joined the European Union in 1973, it switched to burgundy red（酒红色）like other EU countries. The common color was supposed to make European passports instantly recognizable.

    But since colors can't be patented（专利）, nothing stops others with the same idea. A number of countries that long to join the EU have changed their passports to burgundy too. Meanwhile Britain has decided to leave the club. Its government has announced that the UK passports will return to navy blue after Breit（脱欧）.

    If you have a passport from Singapore or South Korea, you are in possession of one of the most powe3rful travel documents on earth. Passport power is measured by the number of countries the holder can access visa-free. Currently sharing first place in the power rankings, Singaporean and South Korean passports provide visa-free access to 162 countries each. British passport holders share fourth place in the power ranking with six other nations, each accessing 159 countries visa-free. Americans ranked fifth with access to 158. Somalia, Syria, Pakistan and Iraq are among the world's least powerful passports. Afghanistan is the lowest ranking of all, with visa0free access to just 26 countries.

    Having to get a visa is not a piece of cake. First there is the never-ending form. Then there are lengthy appointments and expensive fees. Some visas also require travelers to pre-booked flights to prove that they intend to return home.

    But there are unexpected advantages to some of the world's weaker passports. Middle-ranking Namibia is one of just a handful of countries, whose citizens can enter Angola visa-free. India is one of only three countries, whose citizens have visa-free access to Bhutan.

    A low-ranking passport limits your choices, but not your sense of adventure.

    Halloween is a holiday full of tricks and treats and all things frightening and fun. But what happens when you trade your sweets for a scare? The result is always healthier than candy.

    Being frightened can be good for you. Think about your favorite scary books or movies. You are scared but you just can't resist reading or watching them. Being frightened makes your brain flood with healthy chemical substances that excite your mood and release feelings of great excitement.

    When you're frightened, your body also produces a chemical called oxytocin, which helps people bond with one another. So, if you're at a haunted(闹鬼的) house with some pals, that experience can help strengthen your friendship. “Watch people walking out of a haunted house, and you'll see lots of smiles and high fives,” says Dr. Margee Kerr, a sociologist who studies fear.

    There is also some evidence that being scared can help a person manage stressful situations. Things like giving a presentation in front of your class or performing in a school play can make us fearful and anxious. But these experiences help build a sort of endurance to fear that makes us more confident. “You become more comfortable with the physical experience of fear, and so you're better able to work through it during tense situations,” Kerr explains.

    Though some haunting may be healthy, it's important to remember that people experience fear in different ways. What may be fun for one person could be too scary for another. And Kerr notes that kids younger than six and or seven can't separate real and make-believe, so seeing something frightening could have lasting, negative effects.
