Did you know that, in 2016, over 18 million people attended classical concerts in Germany? That's more people than those who went to main league football matches! Earlier this year, Germany continued its celebration of classical music with the opening of a new concert hall in the heart of Hamburg. Germans are incredibly proud of it  and it's the first thing I show to my friends when they come to visit.

    Known as the ‘Elphi' by the locals, the Elbphilharmonie is a beautiful tower of glittering glass sitting atop an old warehouse by the banks of the river Elbe. The plaza(露天广场)is open to the public and from the middle of he city's tallest building, you can gaze across the harbour, miles of rooftops and passing ships below.

    The main concert hall seats over 2000 people and is one of the most advanced music venues in the world. Two smaller concert halls are used for jazz, world and contemporary music. In addition, if you're unbelievably rich, you can buy one of the 45 luxurious apartments lying within the building.

    Construction began in 2007 with a budget of € 241 million and a two-year period. Fast forward ten years, the building eventually opened with a final price tag of over 800 million!

    I consider myself very lucky that the Elbphilharmonie opened during my time living in Hamburg, but unfortunately I haven't yet been able to attend a concert. Everything is sold out for six months! For now, I'm content to visit the plaza to enjoy the impressive views over the  docks and see the innovative architecture up close. Hopefully one day soon. I'll be lucky enough to grab a last-minute concert ticket!

    According to sociologists(社会学家), every modern industrial society has some form of social stratification(阶层). Class, power and status are important in deciding people's rank in society.

    Class means a person's economic position in society. A commonly used classification is lower class, middle class and upper class. While sociologists disagree on how these terms should be exactly defined, they do describe societies like the United States quite well. One study shows that 53% of Americans belong to the lower class, 46% the middle class, and 1% the upper class. Interestingly, a surgeon earning $500,000 a year and a bus driver earning $50,000 a year both regard themselves as the middle class!

    Power refers to the amount of control a person has over other people. Obviously, people in positions of great power (such as governors) exercise(行使)big power, but people who take orders from others have less power. Power and class do not always go hand in hand, however. For example, the governor of a state has great power, but he or she may not belong to a corresponding (相应的)economic class. Generally, however, there is a relationship between power and class. To our knowledge, there aren't too many people who aren't millionaires in the U．S. Senate!

    Status is the honor or respect attached to a person's position in society. It can also be affected by power and class, but not necessarily so. For example, a university professor may have a high status but not belong to a high social class or have a lot of power over others.

    Wild animals are our friends, but many of them are getting fewer and fewer. We should try to protect them. The four animals below are now in danger.

     Tibetan Antelopes

    Tibetan antelopes are medium - sized animals. They mainly feed on grass. They are usually found in groups of about 20. They are killed for their wool, which is warm, soft and fine and can be made into expensive clothes. Although people can get the wool without killing the animals, people simply kill them before taking the wool. The number of them is dropping year by year. There are less than 75,000 Tibetan antelopes left in the world, down from a million 50 years ago.

    Golden Monkeys

    Golden monkeys are mainly found in Sichuan, Gansu, Shanxi provinces and Shengnongjia mountainous area of Hubei Province. Golden monkeys have golden - orange fur. They move around in the daytime, usually in groups of as many as 100 to 200 heads, or 20 to 30 heads. They feed on fruits and young leaves of bamboos. But people are destroying the environment where they live. Trees and bamboos are disappearing, so golden monkeys have less and less to eat.

    Elephants

    Elephants are very big and strong. They are bigger than any other animals on land. They are grey and have long trunks and tusks. They have poor eyesight, but very good hearing and smell. They can lift heavy things and break down branches with their trunks. Elephants are very friendly towards each other and towards their neighbours. Normally, they live in a group for many years. Young male elephants do not leave the group until they are about 12 years old. Now, there are very few elephants in the world. The number of them is becoming smaller and smaller because their living areas are used for fanning. Also, people hunt them for their tusks.

    Wolves

Wolves are not very big. They have grey fur. Solves have very good eyesight, hearing and smell. Wolves' food is various. They eat animals, insects and snails. They are friendly to each other and never attack people. They do not kill for fun. Wolves are in danger, too. They are losing their living areas because people cut down forests. Soon they will have no home or food.

    "Are you going to Seattle?" an anxious-looking woman asked a female traveler at the Amtrak Airport in Sacramento. "No, I'm going to Eugene," the traveler replied. "Oh, I was hoping you could watch out for my daughter, she's never been on a plane before."

    Now, as I am quite a seasoned plane traveler, I know that seats and cars are supplied by destination（目的地）. So I came up to the woman and her frightened-looking daughter, telling them that her daughter could sit with me and that I would take care of her during the journey.

    The plane had arrived 25 minutes late, and people walked in line to get their seats. The conductor wanted to know if there were people traveling together, so I went to the front of the line with the girl and we were arranged to sit next to each other. Once on board, I showed her where to put her package, and took her to the bathroom area. Then we settled down to sleep. In the morning, I showed her the dining room and bought her a drink. She became comfortable enough to do what most 15-year-olds do: talk and text on her mobile phone.

    All through the trip, I made sure she picked up her ID, which had fallen out of her backpack, some money, which had fallen into the crack （缝隙） of the reclining seat, and continuously kept an eye on her. I hope someone takes her under their wing when she flies back to Sacramento.

    I do hope that kindness will spread around the world through these ways. We're conditioned to think that our lives go on with great moments. But great moments often catch us unaware, beautifully wrapped（包裹）in what others may consider a small one.

    A strange object was found in a small city called Carlos Spegazzini, just a short drive from the capital city of Buenos Aires.

    When farmer Jose first found an odd scene in his farmland, he began to dig at the object. However, he quickly found himself running to tell his wife. Jose needed more support if he was going to investigate this strange thing.

    Even the dog was hesitant to investigate. Unfamiliar with the object, man's best friend was not about to jump at it with little concern. Therefore, they chose to call in somebody who has a better idea of what to do.

    When the police first showed up, they were just as stumped as Jose. They knew this object was something out of the ordinary. It might even be something extraordinary, so more questions appeared.

    It quickly became apparent, it was time to call in the big guys. That's right; when you find something that appears to be out-of-this-world, it's time to call in those who study the mysteries of the old world.

    Authorities called in archaeologists who jumped at the chance to study the object. They quickly determined one thing was for certain: the ancient big one that left this behind was absolutely massive! The group was unable to move the shell, as it weighed nearly two tons!

    Clearly, this massive beast was not the only of its kind existing in the modem-day world. Similar fossils had been found in the surrounding areas and had even made their way to museums. But what was the ancient beast?

    According to Gallup's annual Global Emotions report, people all over the world are more stressed than ever before. Nearly 40 percent of adults from 146 countries reported having experienced worry or stress. And it isn't just adults experiencing these high stress levels; experts have also observed a rise in the number of children and youth. According to another study published in EurekAlert, one in five students are so stressed that they've considered self-harm or suicide. The immense stress they face has been proven to be harmful to their health.

    It's no news that stress can trigger anxiety, depression and self-harming behaviors, and cause sleep problems, social withdrawal, angry outbursts and obsessive-compulsive behaviors. We are moving towards a society where an increasing number of us face mental health problems that stem from high stress levels. If stress increases rapidly, how can we fight it?

    It might sound easier said than done but studies have shown that the best way to deal with stress is to change your perception(认识) of it.

    The University of Wisconsin conducted a study of 30,000 Americans. Researchers asked them how much stress they'd experienced in the past year and whether they believed stress was harming their health. The researchers concluded that people in the study who were exposed to large amounts of stress and viewed stress as harmful had 43 percent higher risk of dying than people who viewed stress as a helpful response.

    More interestingly, those with more positive perceptions of stress had the lowest risk of death out of all involved in the study, even lower than those experiencing very little stress.

    A separate study conducted by researchers from King's College London and the University of Marburg showed students with more negative beliefs about stress experienced more physical symptoms, such as headaches, tension and tiredness during a stressful end-of-semester exam period, compared with students who had more positive beliefs about stress.

    These two studies have proven that stress itself is not actually bad. It is the belief that stress is bad that is bad.
