China is the biggest market in the world, and many countries such as Germany, the USA, the UK and Russia do a lot of business in China. Let's have a look at some important tips to help you be successful when dealing with these nationalities.

    First, you must be punctual (准时的) with Germans. Even 5 minutes late makes a bad impression. Being punctual is also very important in the USA. In the UK, it's important to be punctual for business meetings, but nobody expects you to be on time for a social event. Half past seven really means a quarter to eight, or even eight o'clock! With Russians, you should always be on time, though it is not unusual for them to be one or even two hours late!

    It is best to dress formally and wear dark colours when you meet people from all the four countries. In Russia, designer clothes are very common. Don't be surpri if you go to an office in the UK on a Friday and find everyone wearing jeans. Many companies have “dress down Friday”, when people wear casual (随便的) clothes.

    In Germany, first names are only used by family members and close friends, so be prepared to use titles and last names. In the USA you will usually be invited to use first names almost immediately. The British are quite informal and using first names in business is more and more common, especially among younger people. In Russia, however, nobody uses first names, so use titles and last names.

    In conversation, the British and the Americans value humour, and both like to talk about sport. The weather is also a good topic of conversation with the British and the Americans, but avoid talking about politics. In Russia, say positive（肯定的） things about their country, but avoid making complaints. The Germans, however, prefer to get straight down to business!

    So, use these tips, and you will be on your way to a successful international business career!

    Eat your vegetables.Wash your hands.Always say“please”and“thank you”.We are full of advice for our children, but when it comes to money,we often have little to say.As a result,our children may grow up with clean hands and good manners,but without any idea how to manage their money.

    Here are some basics that will help guide them their entire lives:

    Show them the future.If your 13-year-old girl were to save $1.000,invest（投资）it at 8% and add $100 every month,by the time she's 65,she would have $980,983!

    Be careful of credit（信用）.Credit cards can help you buy necessary things and build a credit history,but they must be used responsibly,which means paying off your debt in time.Explain to your children that when you buy something using a credit card,you can easily end up paying two or three times what you would have paid if you used cash.

    Teach patience.Suppose your child wants a new bicycle that costs $150.Rather than paying the cash,give him some regular pocket money and explain that by putting aside,say,$15 each week,he will be able to buy it for himself in only ten weeks.

    Provide incentive（激励机制）.Tell your children the importance of saving."For every dollar he or she agrees to save and invest rather than spend,you agree to add another dollar to the pot,"says Cathy Pareto,expert in money planning.

    Explain your values.Values and money are deeply intertwined（纠缠在一起）,says Eilleen Gallo,co-author of The Financially Intelligent Parent.When your child demands that you buy something,explain why you really don't want to buy it.“You might say,‘I'd rather save that money for your education,'”advises Gallo.Every time you spend or don't spend money,you have a chance to share your values.

    Parents can cut the chances of their children getting fat simply by keeping them longer at table. Just three minutes extra at a family mealtime could help prevent child obesity. Research found that among poor families, the extra minutes at mealtimes made great improvement of a normal weight for the youth. The factors are likely to be communication and the importance of a scheduled mealtime.

    Dr Barbara Fiese said, “Children, whose families have a 20-minute meal over four times a week, weigh less than kids who leave the table after 15 to 17 minutes. Over time, those extra minutes per meal add up and become really powerful.”

    The researchers studied 200 family mealtimes, testing the effects of factors and mealtime behavior of families with children in primary school. They found that families, who said that shared mealtimes were an important part of family life and had special meaning for them, were less likely to have an obese child. Similarly, families, who talked more together and interacted more positively during the meal, were more likely to have healthy-weight children.

    Teaching low-income families how to make the most of family mealtimes was a wise idea. Dr Fiese said, “This is something we can target and teach.” She added, “It's also important to recognize the increasing differences of families and their sometimes complex living arrangements that may challenge their abilities to plan ahead and arrange a single time to communicate with each other.”

    Families in poorer US neighborhoods faced a lot of problems, including poor access to healthy food. But even so, regular high quality family mealtimes made a difference to the children's weight. Dr Fiese said, “Three to four extra minutes per meal will make a healthy weight more possible.”

    I believe children have a very pure sense of humor. Well, I would like to share my experiences with you.

    The other day when I was out with a friend and her daughter Jane at a restaurant, Jane ordered an apple dessert, which was the most attractive dish in that restaurant. However, when she had a bite of the pie, she shouted loudly, "Mom, why does it look good but tastes like rubber?" My friend was uneasy. Then the waiter gave us another dish.

    A child can say funny things. I was at a friend's home for tea and her son, Mark, wanted her to get up. His mom replied, "I can't, because my foot has fallen asleep now." Little Mark then sang a song and asked, "Mom, will it wake up now?" We laughed together.

    The other day we were having an interesting conversation over lunch and my friend, an animal activist (积极分子) , was arguing with another group member. Her son Tommy suddenly stood up, “Mom, people should never be allowed to shoot extinct animals!” That was funny and the child did manage to turn the argument into a pleasant conversation.

    Well, children sometimes really surprise us. I think we can have a lot to learn from them. They can help us understand the simple world through their eyes.

    Here are some great people and their achievements.

    Mary Anderson ­ windscreen wiper.

    Back on a freezing winter's day in 1902, Mary Anderson was travelling by train through New York City. Snow was falling, forcing the driver to stop repeatedly and get out to clear it. Each time the door opened, Mary suffered a gust of sub-zero air. She had an idea: why not make some kind of a rubber blade that could be operated from inside the vehicle? And that's exactly what she did.

    Josephine Cochrane ­ dishwasher

    The dishwasher dates back even earlier to the 19th century, and to the dinner parties thrown by a lady called Josephine Cochrane. As a frequent host, she wanted a machine that could wash dishes faster than people. Her response was to develop what was to become the first commercially successful dishwasher. Interestingly, innovation was in her blood: her grandfather had invented the steamboat.

    Stephanie Kwolek ­ Kevlar

    Kevlar is the lightweight fibre used in bulletproof vests. The material is used by millions every day and has saved countless lives. The super tough fabric is also used in objects ranging from gloves to airplanes. Incredibly, its strength-to-weight ratio(比强度) is five times higher than steel. Again, it was invented by a woman, the American chemist Stephanie Kwolek, in 1964.

    Grace Hopper ­ first compiler(编译程序)

    One of the most important inventions of the 20th century must surely be the computer programme. The world of programming is unbalanced in terms of gender. Men vastly outnumber women, and take home around 30% more pay than their female counterparts on average. But back in the 1940s and 1950s, women were at the forefront of this new field. Grace Hopper is credited with inventing the first compiler in 1952, which serves as the bridge between code and the binary(二进制的) ones and zeros understood by computers.

Coco Gauff used to visit the Grand Slam tournament (大满贯锦标赛) as a kid to see her idols Serena and Venus Williams. Now she is a champion there herself. On Sept 9, the 19-year-old from the US won her first major women's singles title at the 2023 US Open (美国网球公开赛).

After an average start, Gauff surged to a 2-6, 6-3, 6-2 victory over her bigger, stronger opponent, Aryna Sabalenka, from Belarus, who became the new world No.1 the day after the tournament ended.

Unlike the Williams sisters, who have obvious force and power, Gauff is small and slim. But she moves fast on the tennis court. Forbes magazine said, "She is the quickest and perhaps already the best returner of impossible shots in tennis history."

Even though Sabalenka is a very powerful hitter, it felt like she had to finish each point four or five times, as Gauff's defense was so perfect, noted The Telegraph. This ended up frustrating Sabalenka and caused her to make 46 unforced errors.

Gauff thus became the first American teenager to win the US Open since Serena Williams, then 17, in 

1999. When asked about "taking the torch" from the 23-time Grand Slam winner and the similarity between their tennis careers, Gauff told ESPN, "Serena is Serena. She's the greatest of all time... I'd hope to do half of what she did. But I'm not going to compare myself to her. She's some one that I look up to."

Now, Gauff's big win has left tennis fans wondering: When's her next Grand Slam? That's no easy task. Two of the past four US Open women's champions were teenagers at the time, Canada's Bianca Andreescu in 2019 and the UK's Emma Raducanu in 2021, and neither has come close to repeating their success yet. But one thing about Gauff is certain — that at just 19 years old, the sky's the limit.
