Glacier Bay is one of the most famous parks in America, located in the state of Alaska. This park in the southeastern part of the state covers more than 1 million hectares of Alaskan wilderness. It includes mountains, glaciers (冰川), bays, and even rainforests. Glacier Bay supports hundreds of kinds of animals, including many species of birds, fish, bears, whales and sea lions.

    As its name suggests, much of Glacier Bay National Park is covered by glaciers. A glacier is a large area of ice that moves slowly down a slope (斜坡) or valley, or over a wide area of land. Glaciers cover more than 5,000 square kilometers of the park.

    Glacial ice has shaped the land over the last seven million years. The glaciers found in the park today are what remains from an ice advance known as the Little Ice Age. That period began about 4,000 years ago.

    During the Little Ice Age, the cold weather caused the ice to grow and advance. That situation continued until about 1,700s, when the climate began to warm. The higher temperatures caused the ice to start melting. That melting led the huge glacier to separate into more than 1,000 different glaciers.

    The extremely tall and jagged (参差不齐的) mountains seen in Glacier Bay National Park were formed by the ice advancing and then melting over time. The melting of the ice also created water that filled in and created the many fjords (峡湾) within the park. Fjords are narrow parts of the ocean that sit between cliffs or mountains.

    The huge amount of water from the melted ice killed off many kinds of plants. Vegetation returned to the area over the next 200 years. The regrowth in plants also brought back many animals to the land. This return of life to Glacier Bay is why it is sometimes called “a land reborn” by people.

    In the spring of my career, I found myself questioning the choice of my life's work. The students did not appear to be motivated; the paperwork was overwhelming (巨大的) and the constant changes of educational direction were discouraging. But I just could not bring myself to do anything else. “Next year,” I would say, “next year I will switch jobs, make more money and have far less stress.” Next year just never came. I am now in my forties. And while I am no longer in the classroom or at the schoolhouse, I remain an educator. It finally dawns on me that there is no other profession that will let me change children's minds and have an impact on their future. For every student that finally “got it”, for every new teacher that said, “You inspired me to stay,” I get the raise that has never quite made it to my paycheck.

    I was on a plane recently and the flight attendant asked my name. When I told him, he said, “I knew that was you! You taught at my elementary school. You made me take my cap off in the building and told me I was handsome.” He then paused and said, “I think I kept my hat on until you saw me, just so I could get that compliment (赞美). Thank you for making me feel special.”

    We have now entered an age where nothing is private and secrets are hard to keep. Your “friends” are counted by simply clicking a button. Face-to-face interactions are seen by many as unnecessary and time-consuming. Of course, we can do anything online, including teaching and learning. But I guess I am just old school. I want to look into your eyes when the answer finally dawns on you.

    People aren't walking any more—if they can figure out a way to avoid it.

    I felt superior about this matter until the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn't in any hurry, either, I had merely become one more victim of a national sickness: motorosis.

    It is an illness to which I had thought myself immune（免疫的）, for I was bred in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day's walk and the ability to cover such a distance in ten hours as sign of strength and skill. It did not occur to us that walking was a hardship. And the effect was lasting. When I was 45 years old I raced—and beat—a teenage football player the 168 steps up the Stature of Liberty.

    Such enterprises today are regarded by many middle-aged persons as bad for the heart. But a well-known British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper exercises. A person who avoids exercise is more likely to have illnesses than one who exercises regularly. And walking is an ideal form of exercise—the most familiar and natural of all.

    It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the trees, flower, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world, He cannot learn in a car.

    The car is a convenient means of transport, but we have made it our way of life. Many people don't dare to approach Nature any more; to them the world they were born to enjoy is all threat.To them security is a steel river thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.

    I say that the green of forests is the mind's best light. And none but the man on foot can evaluate what is basic and everlasting.

    In the fall of 1959, Freed suffered a bad reputation for rumors of bribery (贿赂行为), and his troubles were too strong to be resisted. When WABC asked Freed to sign a statement swearing that he had never taken bribes, he refused and was fired. Although he later signed such a statement for WNEW-TV, he lost his television show as well.

    Finding himself unwelcome in New York, Freed fled to the West Coast, where he managed to land a daytime disc jockey (流行音乐播音员) job at KDAY in Los Angeles in 1960. Legal problems continued to bother him, though, and he was charged with taking bribes of more than $30,000 from a number of record companies. Publicly, Freed denied that he had ever accepted direct bribes, although he acknowledged that he had accepted gifts from record companies, but only for playing records that he was certain would become hits anyway. After a short time at KDAY, he left when the station management refused to let him promote his live rock ‘n' roll shows. He returned to New York, but not as a broadcaster. At the height of the great enthusiasm for the twist dance, he hosted a Manhattan twist revue (时事讽刺剧), but when this enthusiasm cooled, he found a disc jockey job at WQAM in Miami in 1962. During this difficult period, Freed began drinking heavily and lost his job in Miami after only two months. In December of 1962 he was found guilty in New York of two charges of commercial bribery and was given a six-month sentence and fined $300. This effectively ended his career.

    Freed spent the last years of his life in Palm Springs, California. Although he had redefined what it meant to be a disc jockey and named the music that had become an anthem (圣歌) for the world's youth, he was a disgraced (耻辱的) and broken man, no longer able to work in the business he loved. On January 20, 1965, he died in a hospital in Palm Springs.

    Can you imagine walking into a gym and seeing dogs lifting weights or cats jogging? We're being a bit silly thinking of dogs and cats going to the gym, but we do have a reason. Just like human beings, pets that don't get enough exercise can become overweight.   
   Overweight pets can develop serious health problems just like we can. So, if you have a pet, part of being a good owner is making sure that your pet gets the right amount and kind of exercise.

    Before you start your pet on an exercise program, be sure to schedule a check-up for your pet and ask your veterinarian how much and what type of exercise your pet needs.

    Just like humans, pets need to be started out slowly. Over time, they will get fit and be able to exercise for longer periods of time. If you exercise alongside your pet, you'll benefit, too!

    Starting out, you might want to play with your pet for 15－20 minutes at a time. Gradually, you can turn those plays into several 30－minute walks or jogs each week. If your pet is especially active, you can extend them to an hour or longer.

    Of course, some pets, such as cats, may not be easy to take for a walk or a run. These pets still need exercise, though. Don't underestimate the value of energetic indoor play, such as games of chase, for these types of pets.

    As you start exercising with your pet, here are some things to keep in mind:

    Make sure your pet has plenty of water before, during, and after exercising.

    If you have older pets, don't push them as hard.

    Watch the heat! If you are outside, exercising with your pet will be best early in the morning or later in the day.
