When I was 12, all I wanted was a signet (图章) ring. They were the "in" thing and it seemed every girl except me had one. On my 13th birthday, my Mum gave me a signet ring with my initials(姓名首字母) carved into it. I was in heaven.

    What made it even more special was that it was about the only thing that wasn't being "replaced". We'd been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the " new" stuff (东西) we got was really just to replace what we'd lost. But not my ring. My ring was new.

    Then, only one month later, I lost it. I took it off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.

    Years passed, and a couple of moves later, I was visiting my parents' when Mum told me that she had something for me. It wasn't my birthday, nor was it Easter or Christmas or any other gift-giving occasion. Mum noticed my questioning look. " You'll recognize this one," she said, smiling.

    Then she handed me a small ring box. I took it from her and opened it to find my beautiful signet ring inside. The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom, they found the ring. As it had my initials carved into it, they realized who owned the ring. They'd had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.

    As cultural symbols go, the American car is quite young. The Model T Ford was built at the Piquette Plant in Michigan a century ago, with the first rolling off the assembly line（装配线） on September 27, 1908. Only eleven cars were produced the next month. But eventually Henry Ford would build fifteen million of them.

    Modern America was born on the road, behind a wheel. The car shaped some of the most lasting aspects of American culture: the roadside diner, the billboard, the motel, even the hamburger. For most of the last century, the car represented what it meant to be American—going forward at high speed to find new worlds. The road novel, the road movie, these are the most typical American ideas, born of abundant petrol, cheap cars and a never-ending interstate highway system, the largest public works project in history.

    In 1928 Herbert Hoover imagined an America with "a chicken in every pot and a car in every garage." Since then, this society has moved onward, never looking back, as the car transformed America from a farm-based society into an industrial power.

    The cars that drove the American Dream have helped to create a global ecological disaster. In America the demand for oil has grown by 22 percent since 1990.

    The problems of excessive（过度的）energy consumption, climate change and population growth have been described in a book by the American writer Thomas L. Friedman. He fears the worst, but hopes for the best.

    Friedman points out that the green economy（经济）is a chance to keep American strength. "The ability to design, build and export green technologies for producing clean water, clean air and healthy and abundant food is going to be the currency of power in the new century."

    Many students are involved in social practice besides study. On Monday, April 17, 2017, a unique partnership between Saint Agatha and Phalanx Family Services began. Saint Agatha is a primary school and day care program. Phalanx Family Services is a full-service, nonprofit （非盈利的）organization offering various programming for in-need families living in Chicago.

    Thirteen in-school youths, between the ages of 16~18, started training as young reporters in an eight-week camp organized by the two organizations. The program is designed to teach them how to become city reporters. After completing the program successfully, they will receive a job reporting for one of nine online news about the project.

    The very thought of 13 youths' improving reading and writing levels and hunting for career opportunities in journalism（新闻业）is exciting! Imagine, Chicago youths report positive and inspiring stories about the happenings around Chicago's black and brown communities, which are much better than frightening stories coming from local and national medium.

    I admire Saint Agatha and Phalanx Family Services for training youths in a needed skill set. As I see it, technology has harmed youths' reading and writing abilities. My father often says, “Youth is wasted on the young.” It sounds like the wisdom of the old. But Saint Agatha offers training and the opportunity for youths to take an active part in reporting the happenings and events they experience day to day in order to prove students don't waste youth.

    If you have a chance to take a walk in a park, look carefully at the people walking their dogs. You'll probably find friendly-looking people with friendly dogs; quiet people with quiet dogs; large men with oversized dogs and long-haired women with long-eared dogs. As you've probably noticed, dogs and their owners look alike. Have you ever wondered why?

    These similarities are so common that researchers have tried to explain them. There are two theories (理论): the convergence (趋同) theory and the selection theory. The convergence theory says that as the owner and the dog spend more time together, they influence each other to the point where they grow similar. In other words, they “converge.” The selection theory, on the other hand, says that owners are interested in dogs that look like them, so they choose those dogs as pets.

    Recently, researchers at the University of California decided to test the two theories by taking pictures of 45 dogs separately from their owners. Then they asked some students to match the dogs' photos with their owners. The students were quite successful with purebred (纯种的) dogs: they correctly matched 16 out of 25 with their owners. However, they had almost no success connecting mixed-breed (杂交的) dogs with their owners. When owners select a purebred dog, they can easily predict (预测) what it will look like later. But that is not true with mixed-breed dogs because it's hard to predict what a mixed-breed dog will look like when it grows up. And since it was the purebreds not the mixed-breeds that looked like their owners, the research seems to prove the “selection theory”.

    But one bit of warning. Although many people look like their dogs, not all dog owners enjoy having the similarity pointed out to them. So, even if the similarity is amazing, don't go up to a stranger and say, “Wow, you look just like your dog!”

    Banff National Park is Canada's first national park. In 1883, on the Canadian Rocky Mountains, three railway workers discovered a natural hot spring, and from there the park was born. Nowadays, it is one of the world's popular tourist spots with great mountain scenery. Every year, millions of people visit it for its wonderful views.

Banff National Park is part of UNESCO's Canadian Rocky Mountain World Heritage site. Located in the heart of the Canadian Rockies, the park has perfect mountains like those on postcards. They are from 45 to 120 million years old, with the highest in the park, Mount Forbes, coming in at 11,850 feet.

    Banff National Park is 80 miles west of Calgary. Calgary's international airport is serviced by major national and international carriers with many flights arriving daily. Open year­round, it offers amazing wildlife viewing and sightseeing, plus many shopping and dining choices, any time of the year. Summer is popular for hiking, mountain biking and cycling, photography, and climbing. The best time for viewing the seasonal color is fall, when the trees turn yellow.

    In winter, the mountain makes exciting downhill (速降) and cross­country skiing. In fact, three major downhill ski resorts (度假胜地) operate within the park. Lake Louise Ski Resort, Sunshine Village, and Mount Norquay combine to offer a large area for skiing, not to mention the backcountry trails available throughout the park. The ski season, which runs from November to May, is one of the longest in North America. Visitors can also enjoy wildlife tours, ice walks, and dogsleds (雪橇).

    Weather in the Canadian Rockies can change quickly. A single day can have a mix of sunshine, snow, wind, and rain, so you should change your clothes. In summer, temperatures average a high of 70 (21 ℃), and daylight lasts until 11 p. m. Autumn brings cool nights and fresh air. Winters can be very cold. In January, the average temperature is 7 ℃ below zero, but by April it is 9 ℃.
