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 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 society of public opinion found 90 percent of people still placing themselves in particular class; 73 percent agreed 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 important 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 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice, Most people said this accent sounded “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 middle-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.

    England continues to be one of the most popular tourist destinations in the world. London in particular is one of the most visited cities and draws people in with its appeal, history, and pubs. England's smaller cities, like Bath and Oxford, are equally as attractive with a lot of culture and fewer crowds. Liverpool, birthplace of The Beatles, has a rich musical history. The countryside has wonderful natural beauty. Here are some tips on traveling in England.

    Free museums—Public museums offer free admission in every city throughout England and the UK. It's a great way to learn about the country's most influential artists and history, and spend a rainy day without paying a cent.

    Book early—Book all transportation well in advance, even if you don't plan to use it. Fares can be around ￡2 with a little planning. The Megabus not only runs buses but also provides trains throughout England and is the best choice for cheap travel throughout the country.

    Pub food—Eating in England can be quite expensive, but for good cheap and filling meals, visit the local pubs, where you can get a good meal for less than ￡10. Besides, the pubs are a great way to meet people!

    Get a Taste of UK card—The Taste of the UK card offers up to 50% off at selected restaurants. You don't need to be an English to get the card, and you needn't pay the first month's membership fee, which is perfect for most travelers.

    Take a free walking tour—Many major cities in England offer free walking tours. They usually last a few hours and are a great way to see the city.

    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates（灵长类）to be cloned. Another one named Tetra was produced in the late 1990s by embryo（胚胎）splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus（原子核）with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer（SCNT）, can create more clones and allows researchers greater control over the edits they make to the DNA.

    Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.

    But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

    Dolphin or not a dolphin? That is the question! You see, there are several types of dolphins. Some are saltwater dolphins while others are river dolphins.

    "What are the 32 types of dolphins?" When people are asking the question, they are actually referring to the saltwater dolphins in oceans and seas. The river dolphins living in fresh water are not included in these species. But what would be the answer in this case if we ask. "Dolphin or not a dolphin?" The answer would obviously be yes. River dolphins still belong to the dolphin family.

    Among the 32 types of dolphins do not actually wear the word "dolphin" in their names, such as the tucuxi, while others actually have the word "whale" as part of their names even if they are not whales but in fact, belong to the dolphin family, for example, the melon-headed whale and the killer whale. So what would be the answer to the question "Dolphin or not a dolphin?" in these cases? It would be yes. All these species do belong to the dolphin family.

    Another question that people ask is. "Are the sea animals that perform at aquariums(水族馆)all dolphins?" So ,it always seems to come back to the question, "Dolphin or not a dolphin?" Well the answer is no in this case. The sea animals that perform there are not all dolphins. The beluga which people tend to think belong to the dolphin family because they show what seems like a smile, like most dolphins, are in fact a species of the whale family.

    Now that you read these facts about dolphins, you probably realize that certain sea animals may appear to be part of the dolphin species and that others seem to be part of the whale family but in either case, it is not obvious and can be surprising when you identify a sea animal as being a dolphin or not a dolphin. That is the question ！

My wife and I were at a crowded grocery store not long ago. It was a weekday evening, cold and wet—and tense. People were carelessly blocking aisles, cutting one another off with their carts.

    Things got worse at the checkout line. The cashier scanned a man's discount card, but he misread the savings on her screen as an additional charge. He decided she was acting deliberately and began to argue.

    "She is being spiteful (恶意的)!" he yelled. "This is unbelievable."

    Other customers looked away as the cashier tried to reason with him. She called a manager, who accompanied him to customer service. Shaken, she moved to the next customer in line.

We've all witnessed uncomfortable scenes like this in public places. The grocery scene was another example of how our trust in others has eroded. But it was also a teachable moment on how we can rebuild our faith—starting with just one person.

    Back at the grocery store, my wife and I reached our uneasy cashier. I grabbed a bottle of water from a nearby cooler and handed it to her. "We felt bad about how that man treated you and wanted to buy this for you." I said. Her face lit up, and we talked as she scanned our items. She told us she had been working that evening through severe foot pain and would be having surgery later that week. We wished her well in her recovery, and she thanked us as we left.

    Those are the balancing acts, the moments of responding social and emotional pain with healing, which will add up to restore trust among people. You can start that pattern in someone else's life, even in a place as ordinary as the neighborhood grocery store.

    Like any new ninth-grader on the first day of school, Joemar Class had ninth-grader- emotion (情绪). He's not used to school in Hartford. He's used to going to school in his home town of Florida, used to seeing his friends, used to having class in Spanish.

    "Nervioso," he said in Spanish.

    We first met Joemar in mid-October in the San Juan Airport. His father, Guillermo Class, had sold his car to buy plane tickets to get his kids and fly them up from Puerto Rico. The island was almost destroyed (毁坏) by the deadly storm—Hurricane Maria.

    Now, they are settling into their new home in Hartford's South End. A week later, and, using his wife's car, Class drove 16-year-old Joemar to his first day at Bulkeley High School. After a short ride, he got out in front of his new school. Inside, he met Gretchen Levitz—the school's program director.

    "I see you have new uniform (校服)," Levitz said. "You look great. Are you ready for a good first day?"

    Then he met couple of teachers.

     "Hello," they each said in Spanish. They asked where he's from, and told him they were happy to see him. Then Levitz took him on a quick tour of the school before classes began—to her office the school store, the library, and the dining hall.

    A total of 19 languages are spoken in Bulkeley High School. "We have so many new students coming here from other countries every single day," Levitz said. "So it's not like he's the only one who has that feeling."

    "You could tell he's little worried," Guillermo said as we left." But, at the same time, he's looking forward to it."
