Many children first learn the value of money by receiving an allowance. The purpose is to let children learn from experience at an age when financial mistakes are not very costly.

    The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance.

    In any case, parents should make clear what, if anything, the child is expected to pay for with the money.

    At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance. The object is to show young people that a budget demands choices between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics.

    Allowances give children a chance to experience the things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save and maybe even invest (投资) it.

    Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance. A savings account is an excellent way to learn about the power of compound interest (利息). That may not seem like a lot. But over time it adds up.

    Anne LaBastille was born in New York City and grew up in New Jersey. Her first experience with the wilderness was in the Adirondacks in the northeast of New York, where she worked at a summer resort to earn money for college tuition by caring for the horses, giving riding lessons, and working as a waitress. And she has many chances to begin her adventure in the Adirondack wilderness.

    Anne returned to school in the fall, but she continued to spend as much time as she could in the Adirondacks. She grew to love her time alone in the mountains. Anne graduated from college with a bachelor's degree in conservation of natural resources and began working for the National Audubon Society in Florida as a wildlife tour leader.

    Although Anne took great pleasure in showing people the animals living in the Florida Keys and the Everglades National Park, she longed for the mountains in the northern parts of New York. Eventually, she decided to build a cabin near Black Bear Lake. Over the years, however, more and more tourists began hiking near her cabin. As a result, Anne decided to build another cabin deeper in the woods at Lily Pad Lake.

    Anne lived in the woods for most of her life. She enjoyed living alone in the woods, and her life was far too busy for her to be lonely. When she was not writing books, she wrote articles for National Geographic, Reader's Digest, and other magazines. In her later years, Anne conducted research in Guatemala on an endangered bird called the grebe. She also lectured nationwide about ecology. Besides, Anne worked with a number of organizations dedicated to conservation.

    As a respected guide, author, and conservationist, Anne not only loved the land but also had found a way to become part of it.

    After spending the first five years of his life in San Diego, Adam Driver's family packet up and moved to a small town in Indiana, where Adam enjoyed a relatively routine adolescence. Then the horrific events of September 11th made Adam's life become anything but routine.

    Just a few months following the events, Driver decided to join the United States Marine Corps. He considered 9/11 as being one of the reasons for joining the army, with his desire to leave Indiana providing the rest. He once said,"I'm grateful for having grown up in Indiana, but I needed to go out and the Marine Corps was a nice, stable option." After serving for two and a half years, and just two months before he was sent to Iraq, Driver injured his sternum in a biking accident. After he was healed, he injured it again during military training, which resulted in an honorable medical discharge.

    After leaving the military, Driver decided to try his hand at acting. At first he studied close to home at the University of Indianapolis, but after just a year, he transferred to Julliard in New York City. He lived in a tiny apartment in Hoboken, New Jersey apartment while studying drama at a prestigious performing arts conservatory（音乐学院）. Following his graduation in 2009, Driver immediately began appearing in plays, including 2010's Mrs. Warren's Profession.

    Adam's first major television experience was a guest spot on Law & Order, and was soon followed by a small role in the award-winning film You Don't Know Jack, which was Driver's first experience working with Home Box Office. Then after landing his star-making role on Girls, Driver was cast in a handful of feature films, including 2011's J. Edgar and 2012's Gayby, Not Waving but Drowning and Frances Ha.

    He'll appear next year in the Coen brother's Inside Llewyn Davis and Steven Spielberg's Lincoln.

    No poem should ever be discussed or "analyzed", until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it.

    All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling 'interpretation' of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching cannot replace the student and teacher reading it or, best of all, reciting it.

    I have come to think, in fact, that time spent reading a poem aloud is much more important than "analyzing" it, if there isn't time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is "a criticism of life", "a heightening of life, enjoyment with others". It is "an approach to the truth of feeling", and it "can save your life". It also deserves a place in the teaching of language and literature more central than it presently occupies.

    I am not saying that every English teacher must teach poetry. Those who don't like it should not be forced to put that dislike on anyone else. But those who do teach poetry must keep in mind a few things about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it.

    What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart disease, cancer, and aging itself, will become distant memories.

    In discussion of technological(技术的) changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs（器官）. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.

    It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

    Many people like traveling, but they cannot take their dogs wherever they go. Some people let their dogs stay alone at home while others ask someone else to take care of their pets. If you're leaving your beloved pet at home for a holiday, it can turn into a bad experience. Luckily, you don't have to worry about your dogs anymore because Rover can cover for you while you are on leave. Rover is the latest service to offer at home dog boarding. It's a good alternative (替代物) to boarding your dog at a dog boarding kennel (狗舍) or your neighbor's house.

    The way Rover works is sort of like Airbnb. Dog owners surf the Rover website or app for pet sitters (照看者), which can be organized by zip code (邮政编码) and available dates. Information of pet sitters is provided, complete with many reviews, specific services and rates. Now Rover has over 25,000 pet sitters in more than 5,000 US cities. And they're all experienced pet sitters.

    After finding someone that meets your needs, just send messages to the pet sitter to arrange a meeting. Then, like Rover says, all that is left to do is relax! Rover's pet sitters are encouraged to send text and picture information throughout the day, and if there's a medical emergency, the site will send a vet (兽医). Besides, don't worry about a pet sitter who fails to help you, because someone else will soon take his or her place.
