The Owl Count

    Annie slept in the front of the seat with her father drovethrough the darkness. “We're almost there!” Dad announced cheerfully. “Soon we'll be observing and counting owls at the state park.” Yawning, Annie noddedand smiled. The time was 4:30 a.m. Looking out into the darkness, Annie remembered learning in school that most owls are active at night, when they hunt for food. During the day they sleep in hard-to-find spots.

    “Dad, why do you need to count owls?” she asked. “It's importantfor the scientists to have current information about bird populations,” he explained. “We want to know which birds have decreased in number and whether any new kinds of birds are coming into a certain area. You and I will write down the kinds of birds that we see today and keep a record of how many times we see each kind. Then we'll send out a report to a scientific organization that is collecting about birds from people all over the country.”

    Dad pulled into the parking lot of the state park. Then, with flashing in hand, they began their hike into the woods. Annie zipped up hercoat and tried to keep from trembling. She had not expected the morning to beso cold. Luckily her gloves were in her pocket.

    Suddenly Annie's father stopped and gestured for her to bestill. Obeying, Annie did not take another step. She thought she heard a low crying up head. “That's certainly a screech owl,” her father whispered. “Let's get a look at it.” After looking more closely, Annie could see that it was asmall owl. Sensing danger, the owl narrowed its eyes and pulled its feathers tightly against its body. Annie carefully wrote down in her notebook that theyhad seen a screech owl.

    Walking a little farther, they came to a tall oak tree. “Thislooks like a perfect spot to attract owls,” Dad said, “I'm going to play a recording of common call of the barred owl. Maybe we can get one to answer." Annie could hardly believe her ear. The recorded call sounded as if the birdwere asking, “Who cooks for you?” Moments later Annie thought she heard areturn call in the distance. She held her breath and waited. Suddenly a huge bird landed very quietly on a branch above them.

    Annie had long forgotten how cold it was. She stood in wonder, shining her flashlight on the bird and studying it carefully. The barred owl was nearly two feet tall. Grey feathers surrounded its dark eyes. The bird did not stay long, but it did not matter. Annie would never forget the image of the powerful barred owl.

    For college students, graduation signals an exciting new beginning. {#blank#}1{#/blank#} Many students wonder: What do I do now? What career is best for me? Most expert advice on choosing careers boils down to the following points.

Knowing Yourself

    What are your interests? Abilities? Skills? {#blank#}2{#/blank#} The results may surprise you! These can be useful, but they're not the last word.

Investigating

    Investigating occupations is much more difficult. For most people, there isn't just one ‘right' job, but several that could be satisfying. {#blank#}3{#/blank#} Talk to people who have occupations that interest you. Find out what they like and dislike about their job.

{#blank#}4{#/blank#}

    Many people choose their careers because they believe strongly in a particular cause. Some might choose to work in areas like medicine, charity or environmental protection. Some have a strong interest in history or a love for the arts. {#blank#}5{#/blank#} So in cases like these, the field is often chosen first, rather than the occupation itself. So if you've chosen a field, self-assessment will help you find your place in it. Invest some time and effort, and find the right career for you.

    Neuroscientists have explained the risky, aggressive or just plain baffling behavior of teenagers as the product of a brain that is somehow compromised. Groundbreaking research in the past 10 years, however, shows that this view is wrong. The teen brain is not defective. It is not a half-baked adult brain, either. It has been forged by evolution to function differently from that of a child or an adult.

    The most important of the teen brain's features is its ability to change in response to the environment by modifying the communication networks that connect brain regions. It allows teenagers to make enormous progress in thinking and socialization. But the change also makes them sensitive to dangerous behavior and serious mental disorders.

    The most recent studies indicate that the riskiest behaviors arise from a mismatch between the maturation of networks in the limbic system(边缘系统), which drives emotions at adolescence, and the maturation of networks in the prefrontal cortex（前额皮质）, which occurs later and promotes sound judgment and the control of impulses. Indeed, we now know that one's prefrontal cortex continues to change noticeably until his 20s. And yet adolescence seems to be starting earlier, extending the “mismatch years.”

    The plasticity of networks linking brain regions—and not the growth of those regions, as previously thought—is key to eventually behaving like an adult. Understanding that, and knowing that a widening gap between the development of emotional and judgment networks is happening in young people today, can help parents, teachers, counselors and teenagers themselves. People will better see that behavior such as risk-taking and turning away from parents and toward peers are not signs of cognitive or emotional problems. They are a natural result of brain development, a normal part of adolescents learning how to negotiate with a complex world.

    The same understanding can also help adults decide when to intervene. A 15-year-old girl's departure from her parents' tastes in clothing, music or politics may be a source of anxiety for Mom and Dad but does not indicate mental illness. A 16-year-old boy's tendency to skateboard without a helmet or to accept risky dares from friends is not unimportant but is more likely a sign of short-range thinking and peer pressure than a desire to hurt himself. Knowing more about the unique teen brain will help all of us learn how to separate unusual behavior that is age-appropriate from that which might indicate illness. Such awareness could help society reduce the rates of teen addiction, motor vehicle accidents and depression.

    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 ℃.
