您好，以下为我的团体见地，码字费时，宿愿您满意：） 望采用哦！Skiing is an incredible sport that involves physical, mental, social and emotional aspects of wellness. Often times winter can bring people into a depression called Seasonal Affective Disorder (S.A.D.). Skiing combines the great outdoor air with physical activity and some sunshine exposure that many people forget physical aspect is obvious, however many individuals, especially those that have never skied before, may not realize how much brain power goes into the sport. Skiing is a proprioceptive activity. Proprioception is an aspect of fitness that is defined as one’s ability to feel the position of different body parts and the effort that goes into moving them. This is almost defines skiing because skiing involves quite a bit of balance and coordination. There are so many slight movements and positions of your body that you must be conscious of to ski well. The more you ski the more you strengthen your ability to be aware of the movement of your body parts. This is important because proprioception weakens with age so the more you are involved in proprioceptive activities the less it will diminish. Skiing prevents aging in more ways than that though. When you ski you carry the weight of your entire body on your feet. Your knees are the joints that endure that weight and must be able to move quickly despite it, so they are being strengthened when you ski. Great news for those that have been skiing for many years; you’ve been strengthening those joints and making an injury later in life less likely the whole time. In addition to strengthening your knees your bones become stronger as well because skiing is a weight bearing activity. So not only are you having a fantastic time gliding down the slopes, but you are preventing knee damage, osteoporosis and increasing your proprioceptive strength. Skiing is also a great way to get some moderate aerobic activity into your day. For most people, skiing is an all day event, so you can imagine the workout your heart is getting without you even becoming winded. It is hardly necessary to mention the social aspect of skiing, but I will for that sake of those that have never been. Waking up at the crack of down to drive an hour or two to spend a day in the freezing cold may not seem appealing to a “winter hibernator.” Add a whole group of close friends that all share the same love for skiing, and you’ve got one heck of a good day. What is unique about skiing is that it brings together people of all different ages and cultures. All over the world if there are mountains and snow, there will be people not only do you have a great group of people having a fantastic time; you’ve got a motivational team that encourages you to get off the couch in the winter and get your heart pumping all day! Try something new this winter instead of being miserable when the first snow falls. If you are already an avid skier, bring someone that isn’t and show them how much fun they are missing!
请给我一些熊的英文简介！
EtymologyModern English bear derives from Old English bera, which itself derives from Proto-Germanic *beron meaning the brown one. (Compare Scandinavian björn, Dutch beer and German Bär all meaning bear) Greek (arktos) and Latin (ursus) have retained the Proto-Indo-European root word for bear (*rtko) but it was ritually replaced in the northern branches of the Indo-European languages (The Germanic, Baltic, Celtic and Slavic branches) because of the hunters taboo on the names of wild animals. For example the Irish word for bear translated means the good calf, in Welsh it translates as honey-pig, in Lithuanian it means the licker and Russian медведь literally means one who leads to honey.[edit] Physical attributesCommon characteristics of bears include a short tail, acute senses of smell and hearing, five non-retractable claws per paw, and long, dense, shaggy have large bodies and powerful limbs. They are capable of standing up on their hind legs. They have broad paws, long snouts, and round ears. Their teeth are bared for defense and used as tools, depending on the diet of the bear. Their claws are used for ripping, digging, and catching. Black bears, and likely other bears, have color on the species, bears can have 32 to 42 teeth. Bear teeth are not specialized for killing their prey like those of cats. Normal canine teeth in a carnivore are generally large, pointed and used for killing prey, while bears canine teeth are relatively small and typically used in defense or as tools. Bears molar teeth are broad, flat and are used to shred and grind plant food into small digestible have four limbs that end in paws. Each paw has five long, sharp claws that are not retractable. These claws can be used to climb trees, rip open termite nests and beehives, dig up roots, or catch prey, depending on the species. While most carnivores tend to walk on their toes in a way that is adapted for speed, bears have a plantigrade stance. They walk with their weight on the soles of their feet, with the heel touching the ground, while the claws of the arm are used more for balance. Although slower than most carnivores, a running bear can reach speeds of up to 50 km/h (30 mph).A bears fur is often long and shaggy. Fur color varies among species, ranging from white, blond or cream, black and white, to all black or all brown. Colors of a bears fur can also vary within species. For example, American black bears may be black, brown, reddish-brown, or bluish-black. Several species, such as the sun bear and spectacled bear have a light-colored chest with facial all bear species, males are larger than females, but the difference between sexes varies and is greatest in the largest species. Large male polar bears may weigh twice as much as females, while smaller male and female bears are much more similar in weight. A bears life span seems to last about 25 to 40 years. Bears living in the wild tend to die younger than their zoo bears are the largest type, and in fact one of the largest extant carnivores, though polar bears are the heaviest. Sun bears are the smallest, only the size of a large dog.[edit] HabitatsBears live in a variety of habitats from the tropics to the Arctic and from forests to snowfields. They are mainly omnivorous, although some have a more specialized diet, such as polar bears who mainly consume fish and marine mammalia. They eat lichens, roots, nuts, and berries. They can also go to a river or other body of water to capture fish. Bears will commonly travel far for food. Hunting times are usually in the dusk or the dawn except when humans are nearby.[edit] BehaviorBears generally lead solitary lives, except for mothers attending their cubs, or males and females during mating season. Bears form temporary groups only when food is plentiful in a small area. Alaskan brown bears group in the same area to feed on salmon during the annual salmon runs, when the fish swim upriver to reach their spawning grounds. Other bears may live alone but exist in a social network. A male and female may live in an overlapping home range, each defending their range from other bears of the same sex. Male young usually leave their mothers to live in other areas, but females often live in an area that overlaps that of their travel over large territories in search of food, remembering the details of the landscape they cover. They use their excellent memories to return to locations where food was plentiful in past years or seasons. Most bears are able to climb trees to chase prey or gain access to additional vegetation. The only exceptions are polar bears and large adult brown bears, whose heavy weight makes it difficult to climb of the larger species, such as the polar bear and the grizzly bear, are dangerous to humans, especially in areas where they have become used to people. For the most part, bears are shy and are easily frightened of humans. They will, however, defend their cubs ferociously if a situation calls for it.[edit] Reproductive behaviorThe bears courtship period is very brief. Bears reproduce seasonally, usually after a period of inactivity similar to hibernation. Cubs are born toothless, blind, and bald. The cubs of brown bears, usually born in litters of 1–3, will typically stay with the mother for two full seasons. They feed on their mothers milk through the duration of their relationship with their mother, although as the cubs continue to grow, nursing becomes less frequent and learn to begin hunting with the mother. They will remain with the mother for approximately three years, until she enters the next cycle of estrus and drives the cubs off. Bears will reach sexual maturity in five to seven years. Bears are generally solitary creatures and will not stay close together for long periods of time. Exceptions have been regularly observed; siblings recently on their own, and sub-adult bears of similar age and status will spend a significant amount of time in informal social groups.[edit] OtherMany bears of northern regions are assumed to hibernate in the winter. While many bear species do go into a physiological state called hibernation or winter sleep, it is not true hibernation. In true hibernators, body temperatures drop to near ambient and heart rate slows drastically, but the animals periodically rouse themselves to urinate or defecate and to eat from stored food. The body temperature of bears, on the other hand, drops only a few degrees from normal and heart rate slows only slightly. They do not wake normally during this hibernation, and therefore do not eat, drink, urinate or defecate the entire period. Higher body heat and being easily roused may be adaptations, because females give birth to their cubs during this winter have been passed in many areas of the world to protect bears from hunters or habitat destruction. Bears in captivity have been forced to be trained to dance, box, or ride bicycles; however, this use of the animals became controversial in the late 20th century. In cartoons, circus bears are frequently depicted riding brown bear is Finlands national animal. In the United States, the black bear is the state animal of Louisiana, New Mexico, and West Virginia; the grizzly bear is the state animal of both Montana and constellations Ursa Major and Ursa Minor represent bears.[edit] Bears as food and medicineMany people enjoy hunting bears and eating them. Their meat is dark and stringy, like a tough cut of beef. In Cantonese cuisine, bear paws are considered a delicacy. The peoples of China, Japan, and Korea use bears body parts and secretions (notably their gallbladders and bile) as part of traditional Chinese medicine. Thousands of bile bears are farmed for their bile in China and Vietnam.

animals in winterHi! Im Snowshoe Rabbit. Im looking for something to eat. But, it is not very easy because the forest is covered with snow and the trees are the winter, people have nice, warm houses to live in, but animals have to stay outside. So, we have to do different things to survive the the winter, you dont see many birds in the forest because most of them have migrated. In the fall, when the weather gets cool, the birds gather together and fly south to warmer people travel they use maps, but when birds travel they do not have any maps. It is amazing that they never get lost; they know exactly where to go. Some birds use the sun, the moon, and the stars to guide you can see some deer, foxes, and rabbits like me in the wintertime. We do not sleep or go away because we like the winter. In the winter, we eat whatever we can find such as moss, twigs, bark, and , there are many animals that sleep during winter unlike me, a rabbit. Many animals like bats, squirrels, skunks, chipmunks, and bears sleep during the winter. That is called sleeping, they save energy and are able to live on very little food. Among them, chipmunks, squirrels, and some other animals are called true true hibernators sleep, the temperature of their body decreases and their heart slows down. So, they need less food. In fact, when you see hibernating animals they look like they are dead. If you touch them they feel very animals, like bears, sleep most of the winter as well. However, they are not true hibernators because their body temperature cannot need to eat a huge amount of food in the fall to keep them warm before they go to sleep for the winter. By the time spring comes, the bears have lost most of their , animals do not sleep all winter long. Some animals can sleep for one month, but many animals only sleep for a few days at a time. When they get hungry, they wake up for a little while and eat some of their hibernating animals have a place in their little homes where they can go to the toilet. Also, if the animals get too cold, they can die. So, on very cold days many animals wake up and try to get warm by shivering. This makes their bodies the pond, many animals hibernate in the winter as well. Some turtles and frogs swim to the bottom of the pond before the water freezes. They dig a little hole in the mud at the bottom, and spend the winter sleeping beneath the frozen about fish? Have you ever wondered what happens to fish when the water is frozen? Most fish stay awake for the winter, but they are very quiet and still. They go down to the bottom of the pond where the water is not frozen and wait for spring to come.
