An autonomous vehicle designed for making local commerce deliveries was uncovered by Nuro. The vehicle is about the height of an SW but far narrower than a typical car. The electric car features four outside compartments（暗格）—two on each side -to hold separate deliveries. Each compartment can be tailored to a specific use, such as cooking a pizza or refrigerating a package.

    “We can use self-driving technology to deliver anything, anytime, anywhere for basically all local goods and services,” Nuro co-founder Dave Ferguson said. “Consumers used to be okay with two-week paid shipping. It became two-week free delivery, followed by one week, two days, and the same day. Now same-day delivery isn't fast enough for some customers.”

    Nuro isn't alone in building robots for local commerce deliveries. Earlier this month, Toyota, a Japanese car company, uncovered a concept vehicle that could be used for package delivery. A handful of startups—including Starship Technologies, Marble and Dispatch—are testing small robots for deliveries on sidewalks.

    Nuro's vehicle will likely face legal hurdles. Fully autonomous vehicles without a test diver aren't legal in California today, and many companies have shifted testing o states where regulators are more welcoming of autonomous vehicles, such as Arizona.

    Nuro expects to face fewer challenges because it doesn't carry passengers. Nuro's narrow size may also be helpful when navigating streets and avoiding pedestrians. The vehicle isn't equipped with any special features to communicate with pedestrians or other road users. Some companies have tested and patented solutions such as digital screens that signal the car's next move. Ferguson said his team conducted studies and found that such techniques could confuse people. Nuro believes it's better to make sure the car performs predictably, so that human drivers know what to expect from it.

    “We feel by creating this new technology that's going to enable this last mile delivery, we're going to be creating new markets and doing things that previously weren't possible,” Ferguson said. “This is not swapping out jobs with robots. It's creating new markets. There will definitely be new employment opportunities.”

    Have you ever looked out of the window of a passenger plane from 30,000 feet at the vast expanses of empty ocean and uninhabited land, and wondered how people can have any major effect on the Earth? I have. It is now becoming pretty clear that we are causing a great deal of damage to the natural environment. And the planes which rush us in comfort to destinations around the globe, contribute to one of the biggest environmental problems that we face today— global warming.

    As usual, people in the developing world are having to deal with problems created mainly by those of us in developed countries. Beatrice Schell, a spokeswoman for the European Federation for Transport and Environment says that, "One person flying in an airplane for one hour is responsible for the same greenhouse gas emissions（排放）as a typical Bangladeshi in a whole year." And every year jet aircraft produce almost as much carbon dioxide as the entire African continent does.

    There is a way of offsetting(抵消) the carbon dioxide we produce when we travel by plane. A company called Future Forests offers a service which can relieve the guilty consciences of air travelers. The Future Forest website calculates the amount of CO₂ you are responsible for producing on your flight, and for a small fee will plant a number of trees which will absorb this CO₂.

    Yesterday I returned to Japan from England, and was happy to pay Future Forests 25 pounds to plant the 3 trees which balance my share of the CO₂ produced by my return flight. Now the only thing making me lose sleep is jet lag.

    Held in Valencia, La Tomatina is a tomato-throwing activity that causes the number of people to increase to more than 40,000 in a town of just 9,000 persons.

    The festival takes place on the town's main square. At 11 o'clock, the third Wednesday in August every year, a large pole(杆) with a ham tied to the end of it is raised into the air, and there is a mad climb as people struggle against each other to pull it down. Once this is achieved, a rocket goes skywards and more than 100 tons of ripe tomatoes are tipped from trucks to the waiting crowd. For precisely one hour, until a second rocket is fired, everyone joins in a cheerful tomato battle.

    La Tomatina began in 1945, but it is not known why. Locals have many theories, including the popular tale of angry townsfolk attacking city councilmen(议员) during a town celebration. However, it could also have started because of anything from an anti-France protest or simply a fun food fight between friends. Whichever way it started, the townsfolk of Valencia enjoyed it so much that it was repeated year after year, finally becoming an officially recognized celebration in 1952. Despite being cancelled briefly during the 1970s for having no religious significance, it has returned every year since then.

    Most people come for the day, arriving on the morning train from Valencia and heading back in the afternoon. But if you want the full La Tomatina experience, stay for the week-long celebration which involves music, dancing, parades and fireworks. The night before the fight, a cooking competition is held where women traditionally dress in white, and men without shirts altogether.

    Protection for the fight is recommended—wear old clothes and shoes and a pair of glasses to protect your eyes. What you don't bring to La Tomatina is also important. The crazy tomato-throwers attack each other with all their strength: cameras are seen as positive invitations to throw at the owner.

    While famous foreign architects are invited to lead the designs of landmark buildings in China such as the new CCTV tower and the National Center for the Performing Arts, many excellent Chinese architects are making great efforts to take the center stage.

    Their efforts have been proven fruitful. Wang Shu, a 49-year-old Chinese architect, won the 2012 Pritzker Architecture Prize -which is often referred to as the Nobel Prize in architecture-on February 28. He is the first Chinese citizen to win this award.

    Wang serves as head of the Architecture Department at the China Department at the China Academy of Art (CAA). His office is located at the Xiangshan campus (校园) of the university in Hangzhou, Zhejiang Province. Many buildings on the campus are his original creations.

    The style of the campus is quite different from that of most Chinese universities. Many visitors were amazed by the complex architectural space and abundant building types. The curves (曲线) of the buildings perfectly match the rise and fall of hills, forming a unique view.

    Wang collected more than 7 million abandoned bricks of different ages. He asked the workers to use traditional techniques to make the bricks into walls, roofs and corridors. This creation attracted a lot of attention thanks to its mixture of modern and traditional Chinese elements.

    Wang's works show a deep understanding of modern architecture and a good knowledge of traditions. Through such a balance, he had created a new type of Chinese architecture, said Tadao Ando, the winner of the 1995 Pritzker Prize.

    Wang believes traditions should not be sealed in glass boxes at museums. "That is only evidence that traditions once existed," he said.

    "Many Chinese people have a misunderstanding of traditions. They think tradition means old things from the past. In fact, tradition also refers to the things that have been developing and that are still being created, "he said.

    "Today, many Chinese people are learning Western styles and theories rather than focusing on Chinese traditions. Many people tend to talk about traditions without knowing what they really are," said Wang.

    The study of traditions should be combined, with practice. Otherwise, the recreation of traditions would be artificial and empty, he said.

    From whale watching to shopping, the activities are as varied as the scenery along Queensland's Great Sunshine Way.

    Day 1

    Morning

    The Sunshine Way begins in Queensland's Gold Coast. Start the day with a visit to one of the Gold Coast's world-class theme parks. Then see stunt (特技) shows at Warner Bros Movie World. You can also jump on exciting rides and visit the new Lego Store at Dreamworld.

    Afternoon

    While the drive to Brisbane only takes an hour, enjoy a trip inland into the Gold Coast hinterland and explore the rainforest hikes and waterfalls in Tamborine, Lamington and Springbrook national parks.

    Day 2

    Morning

    Wake early to climb Brisbane's famous Story Bridge, where you can see the sun rise over the city. From the top, you'll be rewarded with full views over the snaking river, out to Moreton Bay in the east and the green hills of the Scenic Rim to the west.

    Afternoon

    Drive 144 kilometers north to Noosa. Hastings Street is thick with designer fashion stores and impressive restaurants. Explore one of the walking trails that run through Noosa National Park. The Coastal Track is a popular choice. Look out for dolphins and whales between May and November.

    Day3

    Morning

    Continue 185 kilometers north, through the gold rush towns of Gympie and Maryborough to the whale watching capital of the world, Hervey Bay. About 10,000 humpback whales visit it every year, making it the best place to see the ocean giants up close.

    Afternoon

    From River Heads, catch a 50-minute ferry to the world's largest island completely made of sand, Fraser Island. Alternatively, continue 110 kilometers north to Bundaberg. Then travel just east of the city to Mon Repos Beach in time for the sunset.

    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 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 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.
