It was once common to regard Britain as a society with class distinction. Each class had unique characteristics.

    In recent years, many writers have begun to speak of the 'decline of class ' and 'classless society ' in Britain. And in modern day consumer society everyone is considered to be middle class.

    But pronouncing the death of class is too early. A recent wide-ranging study of pubic opinion found 90 percent of people still placing themselves in a particular class; 73 percent agreeed that class was still a vital part of British society.; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an imprtant part of British society. Britain seems to have a love of stratification.

    One unchanging aspect of a British person's class position is accent. The words a person speaks tell her or his class. A study of British accents during the 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice. Most people said this accent sounds 'educated ' and 'soft '. The accents placed at the bottom in this study, on the other hand, were regional(地区的) city accents. These accents were seen as 'common ' and 'ugly '. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.

    In recent years, however, young upper midder-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song ' Common People ' puts forward the view that though a middle-class person may ' want to live like common people ' they can never appreciate the reality of a working class life.

    In a time when ivory poaching（偷猎）has gotten so bad that it threatens to wipe out several animal species,a young Dutch designer is creating "egalitarian（平等主义）jewelry" made of our very own ivory—teeth.

    Lucie Majerus got the idea for her "human ivory" collection after having her wisdom teeth removed.She kept them and soon realized they would make great material for a jewelry collection."Why wouldn't we value our own material instead of the precious material from other species?And what if we mine our own ivory and turn it into pearls?"she asks.

    Her own teeth became a ring,but in order to create a whole collection,she needed more material,and since having more of her teeth removed wasn't a very pleasant choice,she asked her dentist to save his patient's unwanted teeth.Most people choose not to keep their pulled teeth,so they are usually donated to dentistry schools.Majerus also received the lost teeth of two of-her teachers at Design Academy Eindhoven,so she had a nice supply of human ivory to experiment with.

    To turn human teeth into attractive pieces of jewelry,Lucie Majerus first bleaches（漂白）them,and then uses a stone polishing machine to shape the teeth into various shapes.

    Majerus displayed her human ivory jewelry collection at this year's Dutch Design Week,and claims that people's reaction was mostly positive."Surprisingly,most people aren't frightened at the sight of the jewelry,but really like the idea,"Majerus told Fast Co Design."Some regret that they didn't keep their tooth at the dentist and some,who will have teeth taken out soon,are now looking forward to it."

    Traveling can be a fun way to gain life experiences, especially during Spring Break-a week-long school vacation in the United States. But what if you're a student and don't have enough money for a trip？Don't worry. Here are some useful suggestions.

    Save：This probably is the most important preparation for traveling. Cut expenses to fatten your wallet so you'll have more choices about where to go and how to get there.

    Plan ahead：Don't wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security and savings.

    Do your homework：No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

    Plan sensibly：Write down how much you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.

    Travel in groups：Find someone who is interested in visiting the same places. By traveling with others you can share costs and experiences.

    Work as you go：Need more money to support your trip？Look for work in the places you visit.

    Go off the beaten path：Tourist sites may be expensive. You may want to rethink your trip and go to a less﹣known area. Smaller towns can have many interesting activities and sights.

    Pack necessary things：The most important things to take are not always clothes.

Remember medicine in case you get sick, and snacks in case you cannot find a cheap restaurant.

    Use the Internet：The net can help to save money. Some useful websites include www.travelcity.corn, www.bargainslowestfare.corn and www.economictravelcity.com.

    By planning sensibly, even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.

    First aid is defined as the emergency care given to a sick or injured person. The goals of first aid are to prevent death and to prevent injuries from becoming worse. Each emergency condition is different. However, the following rules apply to any kind of emergency.

    Be aware of your limitations. Do not try to do more than you are able to. Nor should you do things if you are unfamiliar with them. Do what you can under the conditions at the time.

    Stay calm. Acting calmly will help the victim feel safe.

    Take a quick look to see if the victim is bleeding, and if there is a pulse.

    Keep the victim lying down and do not move him or her. You could make an injury worse if you move the victim.

    Call for help or ask someone to make the EMS system (急救系统) start.

    Keep the victim warm. Cover the victim with a blanket. Coats and sweaters can be used if a blanket can not be found.

    Reassure (使……安心) the victim. Explain what is happening and that help has been called.

    Do not give the victim any food or fruits.

    Keep the bystanders (旁观者) away from the victim. Bystanders want to have a look, offer advice, and say something about the victim's condition. The victim may believe that the condition is worse than it really is.

    From early times, man has been interested in art. People have often worked together to collect and save the world's art treasures.

    Fine art treasures from many countries are kept in an art museum called the Louvre (卢浮宫) in Paris, France. The works of art have been collected by the people of France over many centuries. It is the biggest art museum in the world.

    The Louvre has not always been a museum. The first building was a fort (堡垒). In 1190, it was the king's castle with high walls and a round tower. It had a moat (护城河) to keep out the enemies.

    Over the years, the number of buildings around the fort grew. By 1350, the fort was no longer needed and became a palace home for French kings and queens. During times of peace, new treasures were brought in. During days of war, many treasures were stolen, and the buildings were damaged.

    When Francis Ⅰ became King of France in 1515, he brought in many artists from many countries. One of the artists was Leonardo da Vinci from Italy. He worked in Paris. Da Vinci's Mona Lisa is the best-known painting in the museum today.

    In 1793, the Louvre became a public museum, just as it is now. It is a place where art treasures are kept for everyone to enjoy. Every year millions of people from all over the world come to the Louvre to see the master-pieces.

    About three decades ago, China was known as the "Bicycle Kingdom".But the two­wheeled transport's popularity began to fade, with many bikes soon replaced by their fuel­powered competitors.

    But recent months have seen a renaissance of the bike across China, with an increasing number of people choosing cycling instead of driving to schools, to workplaces or to do sightseeing. The introduction of bike­sharing schemes, first developed by new companies like Ofo and Mobike, has brought the trend to a new level. According to data from iResearch Consulting Group, the first week of this year saw 5.85 million active users of Mobike while Ofo had 1.4 million active users.

    People can unlock the shared bikes by simply using their smartphones. The bikes are equipped with GPS and can be left anywhere in public places for the next user. They're popular among many Chinese people as they provide an effective answer to the "last mile" problem, which refers to a person's final journey. "In places where the subway doesn't reach and where it's difficult to change from one kind of transport to another, it's so easy to get where you want to go with Mobike," Hu Hong, 29, said. She rides a bike to work.

    However, the schemes have also led to problems such as illegal parking, vandalism (故意破坏) and theft. "Bike­sharing is a greener method of transportation and provides a user­friendly experience," said Liu Xiaoming, Vice­Minister of Transport. "But it's a combination of online and offline business. Operators are usually strong in online services, but lack offline business experience."

    In fact, these problems are also shared by bike­sharing schemes abroad. Set up in 2007, Vélib is a large­scale public bike sharing system in Paris. By October, 2009, a large number of Vélib's initial bikes had to be replaced due to vandalism or theft. Bikes were found hanging from lampposts (街灯柱) or thrown into the Seine River.
