In Korea, it is rude to wear shoes inside someone's house because it is considered dirty. In Saudi Arabia, you should not bring food to someone's house because taking food or drink suggests that you think the host cannot afford the meal. More and more people around the world are travelling abroad to study, to go on vacation, or to work, and while it can be a great way to learn about other cultures, there may be times when travelers accidentally annoy their host.

    The same gesture can have very different meanings in different countries. The gesture meaning OK in the United States means something completely different in Brazil as Ella Yao discovered. Ella had travelled to Brazil to study and was living with a host family. During dinner, her host asked Ella if she was enjoying the meal. Because her mouth was full of food, Ella made a sign with her hand that to her meant OK. Although Ella meant the food was good, this symbol in Brazilian culture is extremely rude and her host was deeply annoyed.

    While travelling in Thailand, Elizabeth Brown learned that there are differences in food in the United States and Thailand. She stopped at a small, family-owned restaurant in Chiang Mai and ordered spring rolls. She was really enjoying eating them until she got the last one and noticed that there was an insect inside. She complained to the server. Later, she discovered that although insects are disgusting to most Americans, they are considered a delicacy(佳肴) in some countries.

    All these mistakes can be avoided with some research on cultural differences before you go abroad. However, if you do accidentally annoy someone, quickly apologize, and learn from your mistake.

    Today's workplace is unique in history.Never before have we seen people working together who represent such different backgrounds and experiences.This difference of age,race,gender,and work style makes it very difficult to organize and run a company.

    As a result,companies are looking for individuals who can manage a wide range of employees effectively. Increasingly,managers are discovering that age differences among workers are a major cause of concern.

    This has been an important realization.The management difficulties and challenges have led some experts to study intergenerational differences for an understanding of problems in the workplace.What they have discovered is interesting and may provide ways of improving working conditions in companies that employ individuals from different generations.

    The first thing to realize,they say,is that differences of opinion about the importance of work and how to get work done are not a coincidence.That is,it is not an accident that young employees will be different from older employees.In fact,if employers do not pay attention to these differences,it is possible that anger will build up between people and lead to difficulties in the company.

    Resentment（仇恨）between members of different generations,if not attended to（处理）,can lead to extreme anger and unhappiness and even lasting enmity if people are not careful.That individuals from different generations should come to view each other as if they were from different sides of warring countries should not be surprising.

    It is natural for individuals from the same generation to form alliances（联盟）,to come together for protection. Different generations represent different experiences in life,and these lead naturally to different opinions about oneself and one's approaches to work.

    If you were raised in a time of plenty,when products were readily available and relatively inexpensive,you would believe that prosperity is natural and expectable.If,on the other hand,you were raised in a time of scarcity,you would always be careful not to waste things for fear you would not have enough.You would make angry people who seem to believe that problems will always solve themselves.Such optimism in the face of difficulties would be a source of unhappiness between you and them.It is difficult,in such circumstances,to achieve a happy,agreeable atmosphere in the workplace.

    As you know, there are many fantastic parks in New York City.

    Central Park

    One of the most famous parks in the world, Central Park is a man-made wonder. Not only is it the first public park built in America, but it is also one of the most frequently visited parks, with over 25 million guests per year. Set in the middle of busy Manhattan, its grounds serve as a safe harbor, not only for athletes, and musicians but also for lots of migratory birds each year. One can spend an entire peaceful day wandering its grounds, gazing upon nearly 50 fountains, monuments, and sculptures or admiring its 36 bridges.

    Hudson River Park

    Hudson River Park is a waterside park on the Hudson River that extends from 59th Street south to Battery Park in the New York City district of Manhattan. Bicycle and pedestrian paths, including the Manhattan Waterfront Greenway, span the park north to south, opening up the waterfront for the public to relax. The park includes tennis and soccer fields, children's playground, dog run, and many other features.

    Washington Square Park

    Washington Square Park, located in the heart of Greenwich Village, is a very popular and often crowded place. People from all backgrounds gather to this large square dotted with trees.

    Central Park Zoo

    The Central Park Zoo is a small 6. 5-acre zoo located on Central Park in New York City. The zoo began in the 1860s, making it the first official zoo to open in New York. The zoo was improved in 1934, with the addition of many new buildings ranged in a quadrangle around the sea lion pool. Finally, the zoo was repaired in the mid-1980s and reopened in 1988, replacing the old-fashioned cages with naturalistic environments.

    Many people believe Henry Ford invented the automobile (汽车). But Henry Ford did not start to build his first car until 1896. That was eleven years after two Germans developed the world's first automobile. Many people believe Henry Ford invented the production line that moved a car's parts to the worker, instead of making the worker move to the parts. That is not true, either. Many factory owners used methods of this kind before Ford. What Henry Ford did was to use other people's ideas and make them better. And he made the whole factory a moving production line.

    In the early days of the automobile, almost every car maker raced his cars. It was the best way of gaining public notice. Henry Ford decided to build a racing car. Ford's most famous race was his first one. It was also the last race in which he drove the car himself.

    The race was in 1901, at a field near Detroit. All of the most famous cars had entered, but only two were left: the Winton and Ford's. The Winton was famous for its speed. Most people thought the race was over before it began.

    The Winton took an early lead. But halfway through the race, it began to lose power. Ford started to gain. And near the end of the race, he took the lead. Ford won the race and defeated the Winton. His name appeared in newspapers and he became well-known all over the United States. Within weeks of the race, Henry Ford formed a new automobile company. In 1903, a doctor in Detroit bought the first car from the company. That sale was the beginning of Henry Ford's dream. Ford said: "I will build a motor car for the great mass of people. It will be large enough for the family, but small enough for one person to operate and care for. It will be built of the best materials. It will be built by the best men to be employed. And it will be built with the simplest plans that modern engineering can produce. It will be so low in price that no man making good money will be unable to own one."

    The Model T was a car of that kind. It only cost $850. It was a simple machine that drivers could depend on. Doctors bought the Model T. So did farmers, even criminals. They considered it the fastest and surest form of transportation. Americans loved the Model T. They wrote stories and songs about it. Thousands of Model T's were built in the first few years.

    Liana nervously bit her nails while she waited for the exam to arrive. She looked around the room; hundreds of other law students sat in rows staring anxiously at the tables in front of them. Just as she began to take a deep breath to calm her anxiety, an exam booklet(册子) was placed in front of her. This was the moment she had been expecting ever since she began law school three years ago. She picked up her pencil, and opened to the first page of the bar exam, a test for all students wanting to become licensed lawyers.

    Liana never thought she would want to become a lawyer. Her parents were both artists. Law was something she had not been exposed to as a child. But art made for a tumultuous career—both of her parents had struggled to find jobs and worked round the clock when they were young. Even though they finally seemed successful and happy, Liana wanted something different.

    She was the anchor on her high school debate team, and consistently impressed her competitors with her analytical thinking. "Never argue with Ms. Lakes," her teachers would say. So she chose to major in law. In her mind, she pictured herself in a New York City courtroom(法庭) dressed in an expensive suit, with papers in her hand, waving at the jury(陪审团) in a speech on human rights.

    But now, with the bar exam sitting in front of her, she started to worry. "What if I don't pass? Did I study enough?" Her thoughts raced through her mind. On the first page were seven paragraphs detailing a law situation followed by a series of questions. Liana read through the paragraphs, and quickly scribbled down an explanation of the first question before moving onto the next question. The next few hours went like this as the clock ticked closer and closer to the lunch hour.

    At 12:00 p.m. sharp, a buzzer(蜂鸣器) sounded and everyone was told to put down their pencils and walked out for an hour-long lunch break. At lunch, Liana met her friend, Kevin.

    "How did it go?" she asked. "To be honest, I've no idea. I just kept writing." Kevin said. Liana laughed and said she felt the same way.

    After lunch, the two exchanged words of encouragement. They strolled back into the exam center a bit more refreshed. Liana finished the second half of the exam that day with a better feeling than what she started with in the morning.

    Public Health England (PHE) is targeting pizzas, ready meals, ready meat and takeaways. The government has also required the food industry to start using healthier food and encourage the public to opt for lower calorie foods.

    It is all part of an effort to cut calorie (卡路里) intake by 20% by 2024. The target will point to 13 different food groups, which are equal to about a fifth of the calorie taken by children. If action is not taken, PHE said, it would be prepared to ask the government to pass laws.

    PHE would be strictly monitoring progress by looking at which products people were buying and would be prepared to punish companies which do not take their duties. The government is also organizing a program encouraging adults to consume (消耗) 400 calories at breakfast and 600 each at lunch and dinner.

    At present, adults consume between 200 and 300 calories more than they should each day. PHE chief nutritionist Dr Alison Redstone said the 400-600-600 tip would make it easier for "people to make healthier choices" by being able to judge what they should be eating in each sitting.

    How many calories should we eat? It is suggested that women eat no more than 2,000 calories a day, while men should limit their intake to 2,500. For children, it depends on age. A four-year-old should consume no more than 1,300, while for teens aged 17 and 18, it is about 3,000, but overweight children are eating up to 500 calories more than that.

    Prof Russell Viner, of the Royal College of Pediatrics and Child Health, said it was a necessary move. He said, "Over the past 40 years, there had been a slow growth in food sizes, with pizzas and hamburgers simply much bigger than they were in our parents' time." The convenience of fast food at pocket money prices and the advertisement of unhealthy food and drinks to children add to the problem.
