When you visit Kinderdijk, one of the most visited villages in the Netherlands, you step right into the middle of Dutch history.
Kinderdijk lies in the Alblasserwaard, where the Lek and Noord rivers meet together. Much of the village is near or even below sea level. Although there are canals and dykes (堤坝), the lowlands of the village are still at risk of flooding (洪灾). Among the most deadly floods was Saint Elisabeth’s flood in 1421, which killed thousands after the dykes broke in several places. To deal with this kind of problem, the Kinderdijk windmills (风车) were built around 1740 to move water from the lower areas to higher ground and into the river.
Nineteen of the 20 Kinderdijk windmills remain and were named a UNESCO World Heritage (遗产) Site in 1997. Of the 19 windmills, 16 still have millers who live inside and control the huge sails (翼板) in the wind. These windmills continue to help manage the Netherlands ongoing fight to stay above water.
For tourists, boat tours are offered along the canals and walkways lead from the visitor center to the windmills. Two windmills serve as museums, filled with old millers’ items and photos. You can climb up inside to see how the windmills work. The windmills also are working, so be prepared to feel the whole building shake when the sails turn in the wind.
Each year, about 500,000 people visit the Kinderdijk windmills and the buildings have become a must-see on any trip to the Netherlands. There are some windmills north of Amsterdam that “were built for tourists, but we’re a historical site where tourists come, so it’s the other way around,” says Kinderdijk communications manager Peter Paul Klapwijk. “Tourism is a good way to support our site.”

【推荐1】Shakespeare once wrote that all the world is a stage, but these days it's more like a movie set. Get to know some films to find fantastic film locations(地点) you should check out on your travels.
The Sound of Music
Austria's hills are certainly alive with the sound of music and tourists. Mozart may have been born in Salzburg, but The Sound of Music really put it on the map and now about 70 percent of people visit it because of the movie. Cross Residenzplatz Square and visit the Palace of Leopoldskron where the children in the film fell into the lake.
Troy
Although the Palace of Troy was filmed on sets built at Shepperton Studios in the UK, most of the 2004 movie was shot in Malta and Baja California, Mexico. Malta with historic sites and beautiful blue waters was a good choice to replace Greece. Troy was shot at a host of locations, including Golden Bay, Hal Far as well as Fort Ricasoli(where the city of Troy was constructed). The Trojan horse from the film is now lying on the waterfront in Canakkale, Turkey.
Bridget Joneses Diary
Bridget Jones is brought to life as we watch the work and romance in London. Her special corner flat is above the Globe Tavern by Borough Market, one of the city's oldest and biggest food markets. According to The Telegraph, it would be highly unlikely that she could afford to buy a place like that today since it has risen in value by more than 240 percent.
Harry Potter
J. K. Rowling started writing the Harry Potter books while she was living in Edinburgh, Scotland, so it's no surprise that she set most of the story there. The Hogwarts Express travels through the Scottish Highlands and along the 31 meters high Glenfinnan Viaduct. The second highest waterfall in the UK, Steall Falls can be seen during Quidditch matches.

【推荐2】Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman Empire. But when the empire broke down, this kind of tourism stopped.
In the early 17th century, the idea of the "Grand Tour" was born. Rich young English people sailed across the English Channel(英吉利海峡). They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice(威尼斯) in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The "Grand Tour" was an important part of young people's education—but only for the rich.
In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to "take the waters". They believed that the water there was good for their health. So large and expensive hotels were built in these towns.
In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s, it was easier for people to travel between towns, so they started to go for holidays by the sea. And some started to have holidays in the countryside as cities became larger, noisier and dirtier. Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to faraway countries. The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them.
Thus tourism grew. In 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything—plane tickets, hotel rooms, even food and tourists pay for it all before they leave home. The package tour(跟团游)and modern tourist industry was born.
The first travel agency(旅行社)in China was set up as early as 1949. But tourism did not take off until 1978. In 2002, the industry was worth 500 billion yuan and became an important part of China's social development.

School children are walking in a corn field maze. The corn is cut into tricky passageways that make it difficult to find a way out. The children are from Yorktown Elementary School in Bowie Maryland. They have traveled to Montpelier Farms in Prince George’s County which is also in Maryland. The farm is about 40 kilometers from The White House.
Debbie Pierson is the student’s teacher. “We go on these kind of field trips so that the children will have a hands-on experience of what it’s like to be on a farm,” Pierson said.
In Loudoun County Virginia, there are farms where grapes are grown for use in making wine. Many of the farms let people visit, and drink the wine that is made there. Bill Hatch owns the Zephaniah Farm Vineyard. He holds wine tastings in his home. “We are doubling the number of visitors to our farm every year. We have an average of 250 people on a weekend,” Hatch said.
As more people visit farms, more farmers are adding activities in which visitors can take part.
Malcolm Baldwin owns WeatherLea Farm and Vineyard in Loudoun County. Six years ago, he began letting people be married at his farm. They can also sleep at the farm overnight. Mr. Baldwin says the money he makes from these activities let him keep his small farm operating. “But without the animals, and without the vines, the wedding business wouldn’t be as profitable (有利可图的), because people like to see the vines. They like to see the animals and without which I don’t think this will be a popular place,” Baldwin said.

【推荐1】During the 1980s, hundreds of mysterious circles appeared in fields all over England. Many people thought they were created by aliens (外星人) from outer space. The most common theory was that they were made by spaceships that flattened the wheat as they hovered (盘旋) over the ground. Before long, books were written on the subject, and tourists flooded to see the circles.
1990 was the golden year for the crop circles. Delgado and Andrews released their book “Circular Evidence” which became a bestseller. And a well-equipped team of Japanese scientists arrived to record circle-making action. The crop circles were more complex. Crop specialists were as confused as ever. But the mystery was about to be resolved.
One day that same year, a group of well-known circle experts set up surveillance (监测) equipment on a hill in Wiltshire. They were eager to record the formation of a crop circle. Amazingly, the next day six circles appeared in a field just below them, without the team recording anything. Worse still, when the researchers entered the circles, they found man-made tools in the centre of each circle, which seemed to prove that the circles had been made by humans.
In 1991, Today newspaper published an account of how two men in their sixties had made the circles. The artists showed how they had created the circles at night with ropes and flat boards. The following year, a circle-making contest was organized with a prize of 3,000 pounds for the winner. The third prize was won by a young American, Jim Schnabel, who was working alone. The results proved that it was a lot easier to produce the crop circles than investigators had at first believed. For many people the phenomenon was definitively over. It was all a hoax (恶作剧). Or was it?
The thing is that since then, a great many more crop circles have appeared. And despite heavy surveillance (including government and military satellite cameras) no one has ever been caught actually making a crop circle. So, who is still making these circles? And why?

【推荐2】Writing across Time
When students today need to take notes, they simply reach for their ballpoint pens. For students in the past, writing instruments were not so convenient.
Quill pens
Quill pens were made from large bird feathers. Students sharpened the quills with knives and then dipped them into pots of ink to write. The points needed constant re-sharpening and each dip of the quill provided only enough ink to write one word. Besides these problems, drops of ink often stained the page. Yet, people used quill pens for more than a thousand years. Can you imagine writing with a quill pen?
Brush pens
Chinese students traditionally used brush pens to practice writing characters. Unlike quill pens, brush pens had soft bristles that made smooth lines. Students dipped their brush pens in a pool of ink on an inkstone and then wrote.
Chalk
In the 19th and early 20th centuries, when paper was not easily available, chalk was widely used in classrooms. Teachers wrote with chalk on blackboards while students practiced writing and maths on their own slates (石板).
Fountain pens
Fountain pens were the first pens that stored ink inside, from where it flowed through the metal tip or nib (笔尖) for writing. In the 19th century, they finally replaced quills on school desks. However, even with fountain pens, ink still often spilt out, leaving stains everywhere.
Ballpoint pens
Early ballpoint pens leaked and wrote poorly. Three inventors took almost sixty years to finally solve these problems in the early 1950s. Today two of them, Hungarian journalist Josef Laszlo Biro and French Baron Bich, are known for making the ballpoint pen cheap and reliable. Biro and Bic pens are still hugely popular and useful today.

【推荐3】Chocolate––there’s nothing quite like it, is there? Chocolate is simply delicious. What is chocolate? Where does it come from?
The history of chocolate goes back to the discovery of cacao beans (可可豆). About 4000 years ago, the Americans made cacao beans into a drink and they took it as a gift from nature.
In 1519, the Spanish explorer Hernando Cortex visited Mexico in America. He saw people drank cacao mixed with spices (香料). Cortex took some cacao home as a gift to the Spanish King Charles. Since then, people in Spain began to drink cacao. However, the natural taste of cacao was too bitter for most people. To sweeten it, Spanish added sugar and honey to it. As a sweet drink, it became popular in Europe. By the 17th century, rich people in Europe began drinking cacao drink as a fashion.
In 1828, a Dutch chemist, Conrad J. van Houten started using a new process to remove the fat from cacao beans. He made a machine that pressed the fat from the beans. The resulting powder (粉末) mixed better with water than cacao did. People called van Houten’s cacao powder “Dutch chocolate”—it is the beginning of modern chocolate.
After that, chocolate makers started trying new recipes (配方) with Dutch chocolate. First it was mixed with sugar. Then butter was added to the sweetened chocolate to make chocolate bars. In 1849, an English chocolate maker successfully made the first chocolate bar. In the 19th century, the Swiss started making milk chocolate by mixing powdered milk. Milk chocolate has not changed much since this process was invented.
Today, the United States buys most of the chocolate in the world, but the Swiss eat the most chocolate per person. The most chocolate eaten today is sweet milk chocolate, but people also eat white chocolate and dark chocolate. Chocolate has become a worldwide snack and also a popular holiday gift.

【推荐1】For sports fans, nothing could be better than watching a live event on TV or at a sports field. But there’s nothing worse than that event being called off because of bad weather. Bad light, a water-logged court or too much heat can cause matches to be postponed. But according to the latest research, extreme weather might be disturbing the sporting calendar more than ever in the future.
In one sport, golf, major tournaments like The Open, are already predicted to be victims of our changing climate. In the UK, an organization called The Climate Coalition says that golf courses such as St Andrews could be under water by the end of the century if sea levels rise even slightly. It told the BBC that its research predicts "cancelled football matches, flooded cricket grounds and golf courses sinking into the sea."
The threat to sporting events from climate change has been further highlighted in a new report, officially approved and licensed by the Rapid Transition Alliance. Writing about this for the BBC, Matt McGrath says that "By 2050, it's estimated that almost one in four English football league grounds can expect flooding every year." This will mean fewer matches played, less opportunity to watch the beautiful game and reduced government taxation from ticket sales.
Cricket also faces huge challenges globally as temperatures rise in places like India, Australia and the West Indies. The report says that stadiums in Adelaide and Perth will see a 60% increase in days with temperatures over 40 degrees centigrade over the next decade.
Of course, we know that the solution lies with reducing our carbon footprint. We could travel less to attend sports events, and reduce our waste when we do go. But this latest report finds that sports leaders are generally failing to address the issue seriously. However, because sport is universally popular and can be very influential, maybe it should be players, teams and their sponsors as well as fans who should promote a wide low carbon message to help protect sporting fields—before it’s 'game over'.
1. What is the latest research above mainly concerned with?A.the forbidden sporting events | B.the influential climate change |

【推荐2】The Associated Press gardening expert Jessica Damiano recently reported about the many pictures of strangely shaped tomatoes sent to her from fans of her gardening advice. She said people sometimes question if the tomatoes are okay to cook. “The good news,” Damiano said, “is that their unusual appearance does not affect their taste or nutritional value.”
If you have ever cut open a tomato, you know they are divided into internal parts, called locules (子房室), which contain seeds and a substance called gel (凝胶). Most tomatoes have about four or five locules; other kinds of the fruit, like cherry tomatoes, contain two or three. But when a plant experiences temperature extremes, cell division in the developing fruit can go off track. Temperatures over 32℃ during the day and 27℃ overnight can lead the tomato to form an extra locule. But there is not enough room inside a tomato for the extra part, so it grows on the outside of the fruit. Not every tomato on an affected plant will be strange, however.
“Under the right conditions, this could affect one or two tomatoes per plant, depending on where they are in the development process and what the conditions are,” said Timothy McDermott. He is an assistant professor and extension educator at Ohio State University. “The likelihood of one of your tomatoes developing a locule oddity is estimated to be about one in a thousand,” McDermott said.
The extra-locule change is not the only strange looking caused by extreme heat. Conditions including flower drop, halted fruit formation and ripening can also arise when plants are grown outside their usual temperature limit.
Attach a piece of 40 to 50 percent shade cloth to sticks put into the ground around the plant. Leave it in place from 12 to 4 p. m., when the sun is at its strongest. Then remove it to avoid problems caused by a lack of sunlight. And, when harvesting your crop, remember: the funny-looking tomatoes taste just as good!

【推荐3】There was a time when the word “surgery” used to scare people, and they would try their best to avoid a surgical procedure. The feeling is understandable, as the idea of a large cut on your body is discomforting in many ways. However, thanks to the advances in medical science, surgical techniques have improved considerably.
Compared with the traditional open surgery, minimally invasive surgery (微创手术)has several benefits to offer. Not only is the procedure quick and less painful, but also ensures rapid recovery. Now, surgical procedures, either big or small, are done within a few minutes to a few hours. The best part about the minimally invasive surgery is the painless procedure. The advanced techniques are helping with quality treatments to patients who have to undergo (进行) surgical procedures.
Unlike the traditional open surgery that requires a large cut, a surgeon makes multiple tiny cuts of less than an inch. For the process, the surgeon uses small surgical instruments, such as a tiny tube with a mini camera at one end. Once the surgeon marks the cuts, he then passes the tiny tube through one of the cuts. The doctor monitors the images taken by the mini camera on the screen and uses them as a reference. These images give the surgeon a clear picture of the area undergoing the surgery. After the surgery, the surgeon cleans the cuts and sometimes places a bandage for additional support.
Minimally invasive surgery has become the first choice of patients with multiple medical conditions. In fact, it would not be wrong to say that these surgeries are now the standard surgical procedures for many routine operations. Whether you have a minor issue or want a surgical intervention for a major health condition, it is the best option.

【推荐1】In the classic marriage vow (誓约), couples promise to stay together in sickness and in health. But a new study finds that the risk of divorce among older couples rises when the wife-not the husband-becomes seriously ill.
“Married women diagnosed with a serious health condition may find themselves struggling with the impact of their disease while also experiencing the stress of divorce.” said researched Amelia Karraker.
Karraker and co-author Kenzie Latham analyzed 20 years of data on 2,717 marriages from a study conducted by Indiana University since 1992. At the time of the first interview, at least one of the partners was over the age of 50.
The researchers examined how the onset (发生) of four serious physical illnesses affected marriages. They found that, overall, 31% of marriages ended in divorce over the period studied. The incidence of new chronic (慢性的) illness onset increased over time as well, with more husbands than wives developing serious health problems.
“We found that women are doubly weak when their marriage breaks up in the face of illness,” Karraker said. “They’re more likely to be widowed, and if they’re the ones who become ill, they’re more likely to get divorced.”
While the study didn’t assess why divorce is more likely when wives but not husbands become seriously ill, Karraker offers a few possible reasons. “Gender roles and social expectations about caregiving may make it more difficult for men to provide care to sick spouses.” Karraker said. “And because of the imbalance in marriage markets, especially in older ages, divorced men have more choices among potential partners than divorced women.”
Given the increasing concern about health care costs for the aging population, Karraker believes policymakers should be aware of the relationship between disease and risk of divorce.
“Offering support services to spouses caring for their other halves may reduce martial stress and prevent divorce at older ages.” she said. “But it’s also important to recognize that the pressure to divorce may be health-related and that sick ex-wives may need additional care and services to prevent worsening health and increased health costs.”

【推荐2】The custom of celebrating from the end of January until mid-February has long been popular in Quebec City, Canada. The first large Winter Carnival here, in the world’s snow capital, took place in 1894. Faced with winter’s hardships, the city’s population made this popular tradition into a winter celebration that warmed the hearts of all people.
Interrupted by two wars and then the economic crisis of 1929, the Carnival was held from time to time until the second half of the century. In 1954, a group of business people re-started the festivities. That year, Bonhomme was born and was elected the event’s representative.
The next year the first official Quebec Winter Carnival took place. The Carnival snowballed into a big event and was important for tourism and economic activity in the city.
From one winter to the next, the Carnival enriched its activity program. We have since added even more popular activities, such as winter sports, snow sculptures, and activities based on the traditional Quebec lifestyle, such as dogsled races. The Quebec Winter Carnival is the largest winter carnival in the world today, and is third on the list of Top Carnivals after the famous carnivals in Rio and New Orleans.
1960
The people living along Rue Sainte-Therese created many snow or ice sculptures, and this location became known as Carnival Street.
1964
The name of Bonhomme Carnival and his image became registered trademarks.
1970
A new tradition was born: closing the event with a firework display.
1975
A new activity, called The Break, was created, on Friday from noon till midnight. Many employers gave their employees time off so they could go dancing at the Quebec City Convention Centre. The event continued to be held until 1986, sometimes late into the night.
1977
Until 1991, the Carnival offered a children’s sculpture competition.
1987
The snow bath became part of the program.
1999
Because of the importance of volunteers, the human resources department was created to improve organization.

Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes. Most of them ran from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warning the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.
In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.
