The United States is a country of immigrants. It is a place where people from all over the world come to build a better life. Some immigrants bring their families. Some bring a few of their favorite things. Others come alone with nothing but determination. One thing that every immigrant brings with them is their culture.

    American immigration began in 1607 with the colony (殖民地) of Jamestown. In 1620, another group of people left England to build a settlement in America. They wanted to go to a place where they could practice their religion freely. Then many more people left their homes in Europe to build a better life in America. Many also came to America from Africa. By 1770, more than two million people had moved to America. Later on, more people came to the United States than ever before.

    In cities all over America, you can see different cultures that formed this country. Many things that you may think of as being “American” are actually from a foreign culture. Some of the best examples of this are the foods people eat. Pizza and spaghetti are foods that all Americans know and love. But both of them are from Italy. Baseball is an all-American sport. But the hot dogs that people eat during the game are a type of food that was brought to America by German immigrants.

    Over time, pizza and hot dogs have become a part of what is considered to be American food. In the same way, different groups of people have come together to define what an American is. An American can be a person of any background. An American can be of any faith. An American can be of any skin color. They can speak English clearly. They can speak English with an accent. Each new immigrant adds something new to American culture. It will keep changing as more people come to this country.

    Saber Miresmailli was on vacation in London when, caught in a bit of traffic on London Bridge, he decided to take a photo of Tower Bridge.

    “I noticed the couple,” he said. “At that moment, I did not see anyone from the wedding party or a photographer with the couple, so I took several pictures. Usually, my pictures are not very good given the fact that I don't use flash and I don't stop to compose (构图)-so when we get back after two weeks, I was very surprised to find this one turned out so well.”

    Miresmailli said, “I thought to myself, if it was me getting married, I would have wanted the picture.” So he posted the photo on Facebook and attached a few friends with the hope of finding the couple and passing them the picture. What happened next, he said, “was crazy”. “I received more than 2,000 requests from perfect strangers and lots of positive and negative emails.” Until this afternoon, almost 230,000 people had shared his Facebook post on the photo.

There's also been an uncertain identification of the couple. It's likely that their names are Laura and James. “If it's the right couple,” Miresmailli said, “they are on their honeymoon in Bali and have no idea about the photo. I believe they will be shocked to find out about their fame.”

    Miresmailli said he's been drowned by the interest in the photo. “I just want to give them their picture and go back to work and tend my tomatoes,” he said.

    I have learned something about myself since I moved from Long Island to Florida three years ago. Even though I own a home in Port St, Lucie just minutes from the ocean, an un-controllable urge wells up to return to Long Island even as others make their way south. I guess I am a snowbird stuck in reverse. Instead of enjoying Florida's mild winters, I willingly endure the severe weather on Long Island, the place I called home for 65 years.

    I'm like a migratory bird (候鸟) that has lost its sense of timing and direction, my wings flapping against season.

    So what makes me fly against the tide of snowbirds? The answer has a lot to do with my reluctance to give up the things that define who I am. Once I hear that the temperature on Long Island has dipped into the range of 40 to 50 degrees, I begin to long for the sight and crackling sound of a wood fire. I also long for the bright display of colors-first in the fall trees, and then in the lights around homes and at Rockefeller Center. Floridians decorate too, but can't create the special feel of a New England winter.

    I suppose the biggest reason why I return is to celebrate the holidays with people I haven't seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbors children excitedly open gifts on Christmas? Even the first snowfall seems special. I especially enjoy seeing a bright red bird settling on a snow-covered branch. (My wife and I spend winters at a retirement community in Ridge, and I'm grateful that I don't have to shovel.)

    While these simple pleasures are not unique to Long Island, they are some of the reasons why I come back. Who says you can't go home?

    Experts like to say the best form of exercise is whatever kind you'll actually do. But that may not always be the case; new research finds that people who combine exercise with their social lives may be at an advantage over solitary（独自） exercisers. Tennis, badminton and soccer are all better for longevity(长寿) than cycling, swimming, jogging or gym exercise, according to the research.

    The study was based on data from about 8,500 adults who were part of the Copenhagen City Heart Study. They completed a health and lifestyle questionnaire, which included questions about type and frequency of physical activity, and were monitored by the researchers for around 25 years, a period during which about 4,500 of the subjects died.

    Tennis came out on top in the research. Compared with people sitting all day, those who reported playing tennis as their main form of exercise could expect to add 9.7 years to their life time, followed by badminton (6.2 years), soccer (4.7 years), cycling (3.7 years), swimming (3.4 years), jogging (3.2 years) and health-club activities (1.5 years).

    Tennis likely took the top spot because "it's very interactive," says study co-author Dr. James O'Keefe, a physician at Saint Luke's Mid America Heart Institute. "At every point you're talking. It's just a very natural way to emotionally bond with people, besides getting your exercise." But he adds that the study may not have been able to fully account for the fact that wealthier, better-educated people—who tend to be healthier to begin with—may be more likely to play tennis.

    Activities like running and weight lifting still extend your life and offer plenty of other health benefits. But for the best possible benefits, O'Keefe says gym-goers may want to consider combining those workouts with activities that foster social connection.

    O'Keefe, whose exercise typically includes running and weight lifting, says he's even changed his own behavior because of the study: he and his family have taken up badminton.

    "You can't play badminton without feeling like a kid again," he says. "It's just pure fun."

Four Best Places to Travel for the Summer of 2019

    If you're still deciding where to take your summer vacation, 2019 brings major anniversaries, new flight routes, buzzy museum openings and more. In no particular order, check out our picks for where to travel this summer:

    Salar de Uyuni, Bolivia

    The Salar de Uyuni, or Uyuni Salt Flat, is a vast expanse near the Bolivian Andes that resembles ice. The surreal landscape is actually leftover salt from ancient lakes. A large lounge dome offers a public space with tables, floor cushions and hanging lanterns. Food is provided by Gustu in La Paz, considered one of Latin America's top restaurants. Beyond simply enjoying the food and scenery, guests can hike to the crater of Tunupa Volcano, mountain bike across the Salar or visit the village of Jirira. Come nightfall, on­site telescopes take full advantage of the star­flooded sky.

    Las Vegas

    There's the Park Theater, where up to 5,200 people can enjoy A­list artist residencies: Lady Gaga is currently in residence until November, with Janet Jackson and Cher starting this summer. For good measure, Bruno Mars will also be performing some dates in September. Daniel Humm and Will Guidara, perhaps best known for NYC's Eleven Madison Park restaurant, are behind the NoMad Restaurant and NoMad Bar. And foodies will no doubt want to experience Roy Choi's Best Friend, the first brick­and­mortar restaurant following his hugely successful Korean BBQ truck.

    Nova Scotia

    Nova Scotia often gets overlooked for popular provinces like British Columbia and Quebec, but its quiet charms are worth exploring. Cape Breton Island takes a bit of work to reach, but it's here that you'll find challenging hiking trails, a scenic driving route minus the traffic and real­deal Celtic culture. The Halifax Jazz Festival, held in the province's capital, is considered Nova Scotia's largest music festival, and goes down from July 9­14 on the waterfront.

    Grand Canyon

    It's the Grand Canyon's 100th anniversary as a national park, and there are multiple ways to celebrate this notable occasion. From June 22­29, stargazers can join amateur astronomers for free at the park's North and South Rims for the Star Party. Telescopes will be on hand to find planets (Jupiter and Saturn among them), star clusters and nebulae. There will also be slide show programs with a different focus each night, from protecting dark skies to learning how planets form. Constellation talks and night sky photography workshops are among the free offerings, just allow yourself enough time since you won't be the only one with this idea.

If you take a minute to think about the things that catch your attention, they're usually outsized (the Pyramids of Giza), extraordinarily delicate (a well-composed song), boldly colored (peacock feathers), or shocking (a bolt of lightning or a twist ending). These attention-grabbing things make us curious: Why is it like this? Where did the idea come from, or what made this happen?

From these questions come boundless story possibilities. From those ideas, though, we have to eventually cut them down to the ones worth telling, the ones that will grab and keep our readers' attention. This issue looks at that challenge from a variety of angles. Jane K. Cleland tackles the idea of thematic writing — writing that encourages readers to think about big issues that may or may not affect their lives, but at the very least will make them think What if… Then Jessica Strawser shares nine ways to write more authentic (真实的) child characters in adult fiction to bring a fresh perspective and engage readers. Tiffany Yates Martin takes on the debate of the controversial prologue (序言) — should you or shouldn't you use one? You'll have to read on to find out. When it comes to short fiction, Ran Walker offers tips for making the most of titles and first lines when every word counts. Finally, Amy Cook looks at the topic from a different angle — when your published book has stopped selling but you know it has more life in it, how can you use rights reversion to help it reach a new audience?

Our WD Interview for this issue features one author, Michael Cunningham. I was lucky enough to talk with him about his newest novel, Day, which features everything I love about a Cunningham novel: family drama, global issues made local, and impossibly affecting, heartbreaking prose. His writing advice was some of the most unexpected I've heard.

Maybe you're thinking about what you want to focus your attention on this year. Whatever your goal may be, we are glad to be with you along the way.
