Auckland is New Zealand's largest urban area with a population of just over a million people. It is not, however, the capital, although it was at one time, until the capital moved to Wellington. Auckland is the center of commerce and industry, and is perhaps the most energetic, prosperous and multicultural city in New Zealand.

    The city's landscape is decided by volcanic hills, the twin harbors, bays, beaches and islands. Its nickname “the city of sails” is very suitable. Auckland has more boats for each person than anywhere else in the world.

    Auckland has many volcanic hills, many of which currently afford great views of the city. And Auckland's geography is such that shiny waters seem to attract people from every point. It is a water lovers' best place, with some of the best beaches, swimming, diving, fishing, sailing, windsurfing and water sports in the country.

    Wellington is the capital city of New Zealand. It is also the cultural, administrative and political center of the country. Two aspects of the city that will immediately strike any visitor are the harbor and hilly landscape. Everywhere you go, the sounds and the smell of the ocean hang in the air, and green hills and valleys wrap you in a bear-hug embrace. At night, Wellington offers a spectacular, shimmering(闪闪发光的) cityscape that is unlike almost anywhere else in the world. Even after seeing it for a hundred times, it takes your breath away.

    Wellington is a scenic, windy and diverse place. It has some of the best museums, art galleries, restaurants, and coffee houses in the country. It is the storehouse for the nation's historic, cultural and artistic treasures. Being the first place where European settlers arrived, it also boasts lots of historic streets and buildings.

    Wellington is host to an excellent Festival of the Arts every two years.

    Have you ever considered why you begin yawning too when you see someone yawn? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate it whether or not we actually perform the same action. This explains a great deal about how, we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions, they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example: “The hand took hold of the ball” ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with even more information regarding how humans behave and interact. Indeed, it may turn out to be the equivalent (相等物）for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does — well, perhaps you'll understand why.

    The Coolest Inventions

    An Oceans Vacuum(吸尘器)

    There's a collection of plastic trash in the middle of the Pacific Ocean. It's bigger than Texas and growing. The way to clean it up now is to catch it with nets. That is both costly and slow. Instead, the Ocean Cleanup Project proposes a 62-mile-long floating barrier that would use natural currents to trap trash. If next year's trials succeed, a full cleanup operation would aim to start in 2020. It could reduce the trash by 42% over 10 years.

    Easy-On Shoes

    In 2012, Matthew Walzer, a high school student with a disability, sent a note to Nike. “My dream is to go to college,” he wrote, “without having to worry about someone coming to tie my shoes every day.” Nike assigned a design team to the challenge. This year, they came out with their solution: the FlyEase. The basketball shoe can be fastened with one hand. A pair of Nike FlyEase shoes sells for $130.

    An Airport for Drones (无人机)

    As Amazon, Google, and others get ready for drone delivery service, there is one big question: What kinds of home bases will their drones have? Rwanda, in Africa, may have the answer. There, workers will soon start work on three “drone ports”. The goals is to make it easier to transport food, medical supplies, electronics, and other goods through the hilly countryside. Construction is set to be completed in 2020.

    Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition（营养）“depending on who needs it”.

    Nitrogen（氮）and carbon are shared through miles of underground fungi（真菌）networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons（神经元）in our brains, and when one tree is destroyed, it affects all.

    Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.

    “We didn't take any notice of it” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating new words, and we are often able to know where most words come from.

    Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburger. They did not speak good English, but they ate good food. When some Americans saw them eating round pieces of beef, they asked the Germans what it was. The Germans did not understand the question and answered. "We came from Hamburger." One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like those which the men from Hamburger ate. Then he put each between two pieces of bread and started selling them. Such bread came to be called "hamburgers". Today "hamburgers" are sold in many countries around the world.

    Whether this story is true or not, it is certainly is interesting. Knowing why any word has a certain meaning is interesting, too. The reason, for most English words, can be found in any large English dictionary.

The brain-training app trains people to tap on images of healthy foods but to stop when they see unhealthy snacks, creating a link between these foods and stops. The new study, by the universities of Exeter and Helsinki, found that playing the game about once a day for a month led to an average one-point reduction of junk food consumption.

Generally, people who used the app more also reported great changes in their food intake. One app user wrote, "Really useful. I used to eat junk food two to four times a week and I have reduced this to once a week after using the app regularly for a month. My desire for junk food has been reduced greatly and I no longer eat in the evening mindlessly."

The study used the app's usage data, and the app regularly asked questions about how often users eat certain food, along with other information such as their age and weight. The findings suggested that using the app regularly was linked with big changes in eating habits.

The app is free and it only takes about four minutes per day, so it's something people can do not just at home but at work and elsewhere. "From our results it seems important that you do the training at regular times and don't just stop. Therefore, keep it interesting, so you won't get bored with it. Personalize the app as much as possible and pick the food that you find really hard to resist," said Natalia Lawrence, a professor of the University of Exeter.

The researchers stressed that their findings should be further proved, because there was no comparison group and other factors____(such as the possibility that people who did more training were also more motivated to lose weight) could play a part in the results.
