    A great white shark in a California aquarium attacked two soupfin sharks(翅鲨), causing their deaths. The attack was not a natural action for food, but a kind of response when the two sharks swam too close to the great white. The great white didn't attacked other fellows, but the officials had to move other soupfin sharks to another tank(贮水池)for their safety.

    These attacks had given rise to calls for the freedom of the 88-pound, 5-foot-3- inch shark. The aquarium housed the shark in a huge tank. However, according to experts, the tank was not big enough for the shark. Its nose was bloody from striking the glass of the aquarium. Great white sharks in the wild had a big amount of migration, sometimes traveling 50 miles a day. Because the shark was still young, there was possibility of his growing. As it grows, it can became more troubled in the limited space.

    Aquarium officials said that keeping the shark in the aquarium allowed them to study their behavior that they cannot study with free great white sharks. When they studied behavioral patterns, scientists believed that they can help great white sharks in the wild.

    Since the shark had been on display, the number of people who visited aquarium increased greatly. The one-year-old shark was the longest surviving great white living here. It had been at the Monterey Bay Aquarium for six months. Other great whites did not survive for longer than 16 days in the aquarium.

    Camping is a good way to spend time along with your kids and to show them how wonderful nature can be. Through camping, children can discover new things about nature, such as flowers, birds, and other small animals. Camping gives kids time to get away from all the electronics (电子) of today's culture. So it is necessary to plan exciting and enjoyable family camping trips with your children while they are young.

    When planning your family camping trip, consider the activities your kids like: games, hiking, swimming, boating, bicycling, etc. Select a camping place that has some of the activities the kids are interested in. Meal planning is an important part of your camping trip. Plan the meals together, and kids love to choose what they want to eat.

    When starting to pack for your trip, let the kids pack their own items (物品) . Each person should have his/her own sleeping bag with a luggage (行李) bag to put it in. Personal items should be packed with their sleeping bags. Encourage the kids to put their items in a certain place and always return it when they have finished using it.

    When you have arrived at your campsite, make all the camping activities a family activity, which will help children to realize how important team-work is. Everyone can have his/her own job sitting up the campsite. Meal time can be a fun time. So let the older ones help with the cooking on your outdoor camping stove while the younger ones get the picnic table ready.

    Here are some recommendations for tourists to choose from.

    Banff, Canada

    Banff, located in the Rockies, has a view of tall mountains, deep valleys and lakes, making it the first town to become part of the country's national parks. Tourists can enjoy its beauty by hiking, horse riding and boat trips. Banff was founded in 1883 while a railroad was in construction. It was the water springs that drew the engineers' attention to the place as a settlement. With such a fantastic view, it's no surprise that Banff hosts a number of cultural festivals.

    Lisbon, Portugal

    Lisbon is the capital of Portugal, with the warmest winters of any major European city.

    Belem Tower and Jeronimos Monastery are listed as UNESCO World Heritage Sites. The former was built in the 16^th century as a symbol of Portugal's Extraordinary Age and the latter is one of the greatest examples of the Portuguese late-Gothic style of architecture. The Lisbon Oceanaium is among Europe's finest aquariums. The Museum Calouste Gulbenkian is among the best museums in Europe containing priceless artworks covering 4000 years from ancient Egyptian times to the late 20^th century.

    Portland, US

    Portland is frequently recognized as one of the world's most environmentally-friendly cities because of its well-built pavements, large community of cyclists and convenient public transportation. Us climate is ideal for growing roses and it's called the “City of Roses”. Besides, the seaport is also known as a city of beer: it has the largest number of beer breweries（啤酒厂）of any city in the world. Today's Portland is better known for its music. It's called “the capital of karaoke” and “one of the most exciting music scenes” in the US.

    Bordeaux, France

    Bordeaux attracts tourists with its rich cultural heritage, especially its wealth of architectural treasures. Besides the Cathedral of Saint Andrew dating back to 12^th century, the Basilica of Saint Michael is another one of the city's UNESCO World Heritage Sites. It took 200 years to build from 14^th to 16^th centuries. Other significant buildings include the Grand Theater built in 1780 in the new Classical style and the Stone Bridge built in 1821.

    Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.

    "Our findings suggest that there is something about actively falling snow that causes wolves to slow down," said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. "We don't know the exact mechanism behind that. It's unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation（降雪量）might affect wolves' hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey."

    Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry（测距仪） data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.

    With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.

    "Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources," said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.

    "Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios（设想）but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes."
