Enrique Iglesias is a most successful singer! Born in 1975 in Madrid, Spain, Enrique is the child of the famous singer Julio Iglesias. Enrique's mother is a journalist. His parents divorced in 1978. Although Enrique lived with his mother, she sent him to live with his father because of concerns about her son's safety. Enrique wanted to be a singer secretly, hedidn't wish his father to know that and didn't want to live under his shelter. He sought his dream on his own.

    Enrique released(发行) his first album “Enrique Iglesias” in 1995. This album had a collection of rock ballads(民谣) and fivesingles from it went straight to the top spots in Latin music. This album was followed by another “Vivir” in 1997. Three singles from this album occupied the top spots on the Latin charts yet again! Enrique also found himself nominated(提名) for the“Favorite Latin Artist” at the American Music Awards. By 1998, he had releasedhis 3^rd album, “Cosas Del Amor”. This year Enrique won the “Favorite Latin Artist”. “Bailamos” got him great fame. One of the songs in this album was also used in a movie. With the success of “Bailamos”, Enrique now already had many loyal fans. The album, “Enrique”, was released in 1999.

    The year 2001 brought more success for him. His album, “Escape”had a few singles that reached the top spots. Enrique became a house hold name.This album is his biggest successful album so far. “Hero” and “Don't Turn Offthe Lights” soon turned Enrique into a super star. His next release in 2002 was a Spanish album “Quizas”. This album brought Enrique a “Latin Grammy Award” for the Best Pop Vocal Album. In 2007, he released another album “Insomniac” andthe song “Do You Know” became an instantly popular song.

    The year 2018 will mark the 100th anniversary of the deadliest influenza outbreak in history. It is estimated that the influenza pandemic(瘟疫) of 1918 killed more than 50 million people around the world. Other estimates go much higher. Because of a lack of medical record—keeping, we may never know the exact number.

    The influenza was a fast killer. Some victims died within hours of their first symptoms. Others died after a few days. “Their lungs filled with liquid and they choked to death. ”The 1918 flu pandemic was also different from other outbreaks. It struck many young, healthy people. Viruses usually affect sick or old people.

    Although modem medicine effectively controls many diseases, influenza remains difficult to protect against, The World Health Organization estimates that every year influenza kills 250, 000 to 500, 000 people around the world. Each year, medical scientists develop flu vaccines(疫苗) which offer immunity(免疫)from some influenza viruses. But they can only guess which form of the virus will spread.

    Health officials remain concerned about another flu pandemic. New forms of the flu virus appear regularly. One example was the “swine flu”or H1N1outbreak in 2009. Anthony Fauci, Director of the National Institute of Infectious diseases in the United States says that virus caused a true pandemic.

    To stop the next pandemic, scientists are now researching how to create a universal influenza vaccine. In October 2017, Vanderbilt University Medical Center in the U. S. announced the Universal Influenza Vaccine Initiative. The university said researchers are leading an international effort to develop a universal influenza vaccine that will protect everyone against all forms of the flu anywhere in the world. The university added that researchers will begin tests in early 2018, the Human Vaccines Project, a public—private partnership, is funding the project. However, until a universal influenza vaccine is available, today's seasonal flu vaccine remains important.

    The UK government has announced plans to tackle sources of air pollution, including popular wood-burning stoves, but its Clean Air Strategy, which was unveiled last week, fails to address the real problem.

    Although pollution from woodburning stoves is a relatively new problem for the UK, it has long been a major one in countries such as Canada and New Zealand. And the take-home message from them as to controlling the release of harmful particulates in the air is simple: ban wood burning.

    "There does not seem to be a limit below which there is no impact on health," says Gary Fuller at King's College London, whose team has shown that wood burning is now the source of a third of particulate pollution in UK cities.

    As New Scientist reported last year, families with wood burners are likely to be exposed to the highest levels of pollution and their neighbours are next in the firing line, given that the particulates produced can easily escape from homes. Despite this, the UK government isn't planning a ban. Instead, it wants "to prohibit the sale of the most polluting fuels", such as wet wood. What's more, lots of people with wood burners don't buy wood from shops. Instead, they scrounge it from wherever they can, with building waste one popular source. This is a disaster in pollution terms as treated or painted wood can release highly toxic chemicals when burned. The plan is also to "ensure that only the cleanest stoves are available for sale by 2022". But even the cleanest stove produces eight times as much pollution as a diesel truck, says Fuller.

    Some cities actually required old wood stoves to be replaced with cleaner new ones. That has helped, but wood burning remains a major source of pollution, says Fuller. In most cases, conventional gas central heating plus properly insulating (使隔热) your home is less harmful in global-warming terms than switching to a wood burner.

    Finally, there are separate but related EU laws that set limits on the maximum allowable concentrations of specific pollutants in the air at individual locations. The UK frequently breaches these: London's Oxford Street often hits its annual limit within the first weeks of each year. As a result, the UK government has lost a series of court cases brought by the environmental organization ClientEarth. Separately, on 17 May, the UK and five other countries were referred to the Court of Justice of the European Union for their repeated failures to keep to these limits. If the government really wants to clean up the UK's air, it has a lot more work to do.

    If you think you have two left feet but would love to be a good dancer then why not try your hand at dancing?

    That's exactly what I did five years ago and I immediately fell in love with dancing. To me, dancing is a magical experience: I've become fitter, look younger and feel more confident. I enjoy it so much that I will never give up this healthy pastime.

    It's very sociable as well. You meet people and make new friends while dancing the night away. Haven't you heard stories about how dancing inspired new romances or rekindled (重燃) old ones? My friends Joe and Rena just had their big day a few weeks ago after they met each other at a Ceroc workshop some three years before.

    The word “Ceroc” comes from the French language. Without the complicated footwork, it is easier to pick up by beginners. Another good thing about Ceroc is that while it is a partner dance, you don't have to bring a dancing partner.

    Other popular styles of dancing in the UK include ballroom, belly dancing, lindy hop, salsa, tango and tap dancing, just to name a few.

    No matter what types of dancing you do, one thing is for sure: you will become fitter. For office workers like me, dancing is good cardio exercise after a long day sitting in front of the computer screen. It also strengthens your muscles, improves your coordination(协调) and increases your physical confidence.

    Few people will end up being queens of the dance floor. The aim is not to win a competition but to enjoy the interaction(交流). As long as you do the right moves, keep the rhythm and most importantly keep an encouraging smile to your dancing partners, you will always be a winner!

    The purpose of a map is to express graphically the relations of points and features on the earth's surface to each other. These are determined by distance and direction. In early times distance was often expressed in units of time, for example “so many hours' march” or “a day's journey by river”, but such measurements gave more information about the relative ease of crossing the local terrain than they did about actual distance. The other element is direction, but for the ordinary traveller, whose main concern was “Where do I go from here?” and “How far away is it?”, the accurate representation of direction was not of primary importance. Partly for this reason, written itineraries (行程) for a long time rivaled maps. Even today, certain types of maps, for example, those showing railway systems, may make little attempt to show true directions. Similarly, obvious landmarks along a route were at first indicated by signs, realistic or conventional (惯常的), and varied in size to indicate their importance. Clearly the conventions employed varied with the purpose of the map, and also from place to place, so that in studying early maps the first essential is to understand the particular convention employed.

    The history of cartography (制图) is largely that of the increase in the accuracy with which these elements of distance and direction are determined and in the comprehensiveness of the map content. In this development, cartography has called in other sciences to its aid. For example, instead of determining direction by observing the position of a shadow at midday, or of a constellation (星座) in the night sky, or even of a steady wind, use was made of terrestrial magnetism (地磁学) through the magnetic compass, and instruments were evolved which enabled horizontal angles to be calculated with great accuracy.

    The application of astronomical concepts, and the extension of the knowledge of the world through exploration, encouraged attempts to map the known world. Then astronomers discovered that the earth is not a perfect sphere, but is flattened slightly at the poles, which introduced further refinements into the mapping of large areas. Meanwhile, the demands being made of the map maker were shifting significantly. The traveller or the merchant ceased to be the sole user of maps. The soldier, especially after the introduction of artillery, and the problems of range, field of fire, and dead ground which it raised, demanded an accurate representation of the surface features, in place of the earlier conventional or pictorial delineation (描绘), and a solution in any degree satisfactory was not reached until the contour (等高线) was invented.

After releasing a short video on April 27 about planting and cooking peas, Chinese food blogger Li Ziqi witnessed her followers on YouTube go beyond 10 million.

This puts Li, who shot to fame with short videos recording her traditional and peaceful lifestyle in China's countryside, among the ranks of the most popular Chinese-language content creators on the platform.

"It's really surprising. I didn't expect such a wide response," Li told Xinhua in an interview, noting she was surprised by how foreign fans were taken with her works. "What I present is just a lifestyle I've long followed and appreciated," she said. "Maybe it's also what many other people have valued."

Li's YouTube videos center on her life with her grandmother in the rural parts of Sichuan Province. In the videos, Li, often dressed in graceful traditional dresses, rises at sunrise, rests at sunset, plants seeds and harvests flowers, cooks Chinese dishes and crafts bamboo furniture. Unlike many other food bloggers, Li's videos set China's countryside as the stage and start with how the foods are planted and harvested on the farm. She rarely speaks in the process.

Li's overseas followers have praised her videos for showing the amazingly charming, simple and beautiful side of China's rural life, but back home, there have long been debates on whether her presentation is unrealistically poetic.

In response, Li, who was raised in the countryside, said she never needs special arrangements when shooting a video about rural life as "everything is in my mind." "In the countryside, planting flowers, vegetables and trees is not difficult. There are tough elements of rural life of course, but I didn't put them in my videos," Li said. "Most people today are facing much stress in work and life, so I hope they can feel relieved and relaxed when watching my videos."
