You have probably been told by your high school instructor that writing is an important and practical skill. However, you may not be convinced that the ability to write will be important in your own future. If so, you will be surprised at the results of a recent survey by the National Institute of Education. More than four thousand working men and women who had graduated fifteen years earlier were asked to name the courses they would have taken in college if they had known better. The designer of the survey expected people to name courses in computer science, mathematics, or business. But the course most often mentioned was writing.

    If you already have a job, you are probably not surprised at their answers. Many jobs require the ability to write. Despite the increasing use of the telephone and the computer, much information must be communicated in writing.Some ten million people—managers, engineers, sales representatives, and many others— write regularly as part of their jobs. Summaries, reports, reports, letters and speeches are required in today's work world. The ability to write, therefore, is an important skill. The successful individual is almost always the one who can communicate successfully in writing.

    Writing communicates your thoughts and feelings to others; it also tells you something about yourself. Maybe this is what Eldridge Cleaver had in mind in his autobiography, “I started to write... to save myself...I had to seek out the truth... I had to find out who I am and what I want to be ,what type of man I should be ,and what I could do to become the best of which I was capable.”

    It is a tall tale（夸张的故事）that terrifies most young children. Swallow a piece of chewing gum and it will remain in your body for seven years before it is digested. An even worse tale is that swallowed（吞） gum can wrap itself around your heart.

    But what does happen if you should accidentally eat a stick of gum? Chewing gum is made out of gum base, sweeteners, coloring and flavoring. The gum base is pretty indigestible(难消化的)—it is a mixture of different ingredients (成分) that our body can't absorb.

    Most of the time, your stomach really cannot break down the gum the way it would break down other foods. However, your digestive system has another way to deal with things you swallow. After all, we eat lots of things that we are unable to fully digest. They keep moving along until they make it all the way through the gut (肠子) and come out at the other end one or two days later.

    The saliva (唾液) in our mouths will make an attempt at digesting chewing gum as soon as we put it in our mouths. It might get through the shell（壳） but many of gum's base ingredients are indigestible. It's then down to our stomach muscles—which contract(收缩) and relax, much like the way an earthworm moves—to slowly force the things that we swallow through our systems.

    Swallowing a huge piece of gum or swallowing many small pieces of gum in a short time can cause a blockage within the digestive system, most often in children, who have a thinner digestive tube than adults—but this is extremely rare.

    Tulips(郁金香) are the national flower of Iran and Turkey. The European name for the flower is a misuse of the Persian word for turban(头巾), a mistake probably arising in the common Turkish custom of wearing flowers in the folds of the turban. Alternatively, the misuse may have arisen because this eastern flower, when not yet in full bloom, looks like a turban. In Persia, to give a red tulip was to declare your love for someone. The black center of the red tulip was said to represent the lover's heart, burned to a coal by love's passion.

    Originally growing in the Ottoman Empire (present-day Turkey), tulips were imported into Holland in the sixteenth century. When Carolus Clusius wrote the first major book on tulips in 1592, they became so popular that the tulips in his garden were stolen from time to time. As the Dutch Golden Age grew, so did this colorful flower. They were commonly seen in paintings and at festivals. In the mid-seventeenth century, tulips even created the first economics bubble（泡沫经济）, known as "Tulip Mania". At that time, tulips were so expensive that they were used as money until the market for them crashed.

    Today, Holland is still known for its tulips and other flowers, often sincerely called "the flower shop of the world." Tulips are planted in great fields of beautiful color, and transform the landscape into a sea of different colors. Tulip festivals are held throughout the country in spring. However, the most well-known tulip festival is organized in the Noordoostpolder, a province in the central Netherlands, each year. Held in the middle of the tulip fields, this flower festival runs from late April to early May. The Dutch people took their love of tulips abroad when they settled, and tulips and tulip festivals are now found in New York and Michigan, where the connection to their Dutch roots is still very strong.

    Photography is a very popular art form. Anyone with a camera – or a mobile phone – can practice it. A picture communicates in a way that words often can't. As the photographer Destin Sparks put it, "Photography is the story I fail to put into words." And there's no better opportunity to practice the art of photography than during our vacation time.

    Holiday photos have been a part of the culture of travelers for a long time. For decades, vacationers have made sure they've packed a camera along with bathing suits, Hawaiian shirts and sunglasses. A camera is an important holiday item. But over the last 10 years, photography has become much more popular. It's easy to capture (捕捉) still and moving pictures of places of interest, and it's also easy to show off these pictures on social media. Armed with their smart phones, tourists, this year more than ever, are capturing the beauty of our planet.

    Of course, travel companies have caught on to this. Trekksoft has an example of photo-tourism from the United States, a land with a vast choice of beautiful locations. Antelope Slot Canyon Tours in Arizona specializes in tours of the state's famous canyons（峡谷）, which gives photographers the opportunity to capture them on camera.

    Not that any great technology is needed for this: most of the tourists are able to make beautiful images with just their mobile phones. Still, help is on hand from the tour guide for those who aren't great at using their cameras. These tour guides have taken a course in photography in case the skills they've learned would help their customers.

    Many independent Chinese women like to earn their own bread, even if their husbands are already bringing home the bacon. But a recent survey suggests that such women find more joy from relationships, rather than successful careers.

    About 73 percent of the 7,000 women surveyed in Beijing, Shanghai and Guangzhou said they would choose to work even if their husbands earned enough for the family. The survey also found that 77 percent define happiness as "enjoying a relationship".

    But striking a balance between career and family can bring challenges to the woman's career advancement.

    "In my company, women usually have an equal or even a higher starting salary than men," said Li Hua, general manager of Beijing Chuangjiashe Book Circulation Company. "However, as they begin to climb up the career ladder, women often meet problems along the way, while men can climb the ladder more easily."

    Both physical and emotional differences can prevent some women from taking tough positions, Li said. But family life is often the main difficulty for Chinese career women.

    Despite these challenges, however, some experts believe it's reasonable for some women to want to be breadwinners.

    "In this way, the roles of a family are decided by the parents' abilities rather than their gender（性别）," said Gu Donghui, a sociology professor at Fudan University.

    Gu says women should have the freedom to decide if they want to stay at home or work to support the family. "Everyone has a different interpretation（解释）of what it means to find self-worth".

    Wang Haibin, an economic expert from Renmin University shares that view: "Traditionally, we tend to regard the family as the cell unit of society. Some members have always been expected to make sacrifices for it. But, it really doesn't matter who earns more. Economic independence and personal choice is essential for both sexes in the family."

    Kaitlin Woolley and Ayelet Fishbach report in Psychological Science that a meal taken "family-style" from a central plate can greatly improve the outcome of later negotiations.

    Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of competition. However, they also reasoned that it could instead lead people to become more aware of others' needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments.

    For the first test they recruited 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed tortilla chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began.

    The game asked the participants to negotiate an hourly wage rate during a fictional strike. Each person was randomly assigned to represent the union or management and follow a set of rules.

    The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster（in 8. 7rounds）than those who did not（13.2 rounds）. A similar experiment was conducted with 104

participants and Goldfish crackers（饼干）, this time negotiating an airline's route prices. The results were much the same, with the food-sharers negotiating successfully 63. 3%of the time and those who did not share doing so 42. 9%of the time.
