However, there is some difference in lifestyle between city settlers and the country people. Almost 90 percent ofthe population lives in the fast-paced cities along the coast and has little more than a passing familiarity with the desert. The major cities preserve images of colonial heritage, but on the whole the impression is modern, with new buildings reflecting the country's youth. In contrast, therural communities tend to be slow-moving and conservative. For many years, Australia was said to have "ridden on the sheep's back" , are ference to wool being the country's main money earner. However, it is nolonger dominant ( 主宰的). Much of Australia's relatively sound economy is now achieved from natural coal and wheat, and by being the largest diamond producer in the world. Newer industries such as tourism and wine making are also increasingly important. Australians are generally friendly and relaxed, with a modest sense of humor.

    Yet, contrary to wide spread belief, very few Australians have true prisoner origins. Within only one generation of the arrival of the First Fleet in 1788, Australia had become a nation of immigrants. Originally coming almost entirely from the British Isles, today one in three Australians comes from elsewhere. Australia's liberal postwar immigration policies led to a flowing of survivors from war-torn Europe. The emphasis has changed in recent years and today the majority of new immigrants are from Southeast Asia. Today Australia is a "mixture of nations" and although some racism exists, it has generally been a successful experiment and the country is reasonably proud to have one of the most harmonious multicultural communities in the world.

    Climate change has had a number of effects on cities around the world, including rising see levels. And, this has become an especially big problem for coastal cities. City officials must now prepare for higher tides on their coasts. The American city of Miami is one example. Located in South Florida, Miami is home to nearly 3 million people and billions of dollars in land and buildings.

    Miami is one of the cities in America most at risk for rising sea levels. The waterfront is central to Miami's culture and economy. But as the seas rise with climate change .the water will not stay put. Large parts of South Florida are in danger of being under water in the coming years. Across Biscayne Bay, the City of Miami Beach is making improvements - raising streets, adding water pumps and more.

    It is costing the city a lot of money. Local communities will spend 500 million dollars for the improvements. Thankfully, the residents, the folks that are paying the bill for this work, realize that the cost of doing nothing is much greater. A possibility officials are discussing with residents is for city to buy homes in some places where flooding has been a problem. The city would then turn that land into parks of grassland that could hold the water.

    Over time, the city may need to take bigger risks. Miami's future depends largely on how much, and how fast, the oceans rise.

    Caroline Lewis leads the climate activism group, the CLEO Institute. She says cities cannot avoid the need to move inland. But, she says，a well-planned withdrawal (撤退) could include measures to keep people safely in place for as long as possible. And, she says, the world could learn from such a model. In these two Florida cities built on wetlands, there remains a lot of hopefulness.

    Photography（摄影） 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 chance 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 chance to capture them on camera.

    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 people, both men and women in the world love drinking. The popular wisdom for years has been that drinking in moderation (适度) —that's one “standard” drink a day for women and two for men—is linked to a lower risk of cardiovascular (心血管的) disease. But recent studies are casting some doubt on that long-held learning. Science now says it depends on your age and drinking habits.

    A 2017 study of nearly 2 million British with no cardiovascular risk found that there was still a modest benefit in moderate drinking, especially for women over 55 who drank five drinks a week. Why that age? Alcohol can influence the substance in the blood in positive ways, experts say, and that's about the age when heart problems begin to occur.

    Also, a 2018 study found that drinking more than 100 grams of alcohol per week—equal to roughly seven standard drinks in the United States or five to six glasses of wine in the UK—surely increases your risk of death from all causes and in turn lowers your life expectancy. Links were found with different forms of cardiovascular disease, with people who drank more than 100 grams per week having a higher risk of stroke, heart failure.

    Another 2018 study found that consistently drinking moderately, within the recommended amount of alcohol, had a protective effect on the heart over time. Unstable drinking habits were associated with a higher risk of heart disease, which the authors reflected might indicate broader lifestyle changes, such as poor health or stress. Former drinkers were also at greater risk.

    Overall, however, the latest thinking is that any heart benefit may be outweighed by other health risks, such as high blood pressure, certain cancers and liver damage.

    Women who drink are at a higher risk for breast cancer; alcohol contributes about 6% of the overall risk, possibly because it raises certain dangerous hormones in the blood. Drinking can also increase the chance you might develop liver, mouth and oral cancers. One potential reason： Alcohol weakens our immune systems, making us more likely to inflame (发炎)—a driving force behind cancer.

    A new study by the British government has discovered the mental well-being of the country's teenage girls has worsened.

    The survey, which included 30,000 14-year-old students, showed 37 percent of the girls with psychological stress, rising from 34 percent in 2010. British boys' stress level was actually seen to fall over the same period, from 17 percent to 15 percent. The report's authors pointed out the "arrival of the social media age" could be a major contributing factor for increasing stress among teenage British girls.

    "The adolescent years are a time of rapid physical, cognitive and emotional development," Pam Ramsden, a lecturer in psychology at the University of Bradford in the United Kingdom, wrote in a recent blog post. "Teenagers interact with people in order to learn how to become competent adults. In the past, they would engage with parents, teachers and other adults in their community as well as extended family members and friends. Now we can also add social media to that list of social and emotional development." Throughout adolescence, girls and boys develop characteristics like confidence and self-control. Since teenage brains have not completely developed, teens don't have the cognitive awareness to keep from posting inappropriate content. Furthermore, this content can easily be circulated far and wide with disastrous implications.

    "Social media can also feed into girls' insecurities about their appearance," Ramsden said. These sites are often filled with images of people with body type unattainable to the normal person. However, these images and the messages tied to them creep into social standards.

    "Social media allows girls to make comparisons among friends as well as celebrities and then provides them with 'solutions' such as extreme dieting tips and workouts to reach their goals," Ramsden said. "Concerns about body image can negatively impact their quality of life preventing them from having healthy relationships and taking up time that could be better spent developing other aspects of their personalities."

Plan your vacation. The following four places are your fantastic destinations. You can enjoy a completely different experience.

Israel

If you're looking for a once-in-a-lifetime experience, National Geographic 'Travel says visitors should head to Jerusalem to celebrate Easter with thousands of pilgrims (朝圣者). If the crowds get too huge, visitors are told to take a boat ride to King Herod's 2,000-year-old Masada fortress (要塞) or set off on a peaceful morning boat ride across the sea of Galilee.

Panama

Costa Rica and the Caribbean often enjoy much more popularity than Panama, but visitors should consider the centre American country if they want a "less-crowded paradise". The travel site states, "Here, horses are still the primary means of transportation and local fishermen serve fresh seafood and fruit from their home kitchens for roughly $ 6 a plate."

Svalbard

If you're a fan of winter activities, but are in need of some sun, then perhaps a trip to Svalbard is a good choice. National Geographic Travel notes, "The Norwegian archipelago of Svalbard is located about 620 miles south of the North Pole. In late spring, the sun never falls below the horizon—meaning you can take in all the Vitamin D you desire." Popular activities in the area include hiking and wildlife spotting.

Namibia

During spring, Namibia is regarded as the perfect destination with reduced travel costs on cooler evenings. In late May, National Geographic Travel says that the watering holes start to dry up again, which attracts giraffes and black rhino from their hiding spots. If you're fond of adventurous exploration, head to the Namibia Desert for a spot of sand boarding.
