Blind imitation is self-destruction. To those who do not recognize their own unique worth, imitation appears attractive; to those who know their strength, imitation is unacceptable.

    In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes and turned out some tasty dishes. But soon I grew bored. Why follow someone else's way of cooking when I could create my own? Imitating role models is like using training wheels on a child's bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.

    In daily life, imitation can hurt us if we subconsciously (下意识地）hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others.

    In the field of entertainment, our culture praises and admires celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors.

    Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.

Study your role models, accept the gifts they have given, and leave behind what does not serve you. Then you can say, "I stand on the shoulders of my ancestors' tragedies and declare victory, and know that they are cheering me on."

    I grew up in a house where the TV was seldom turned on and with one wall in my bedroom entirely lined with bookshelves, most of my childhood was spent on books I could get hold of. In fact, I grew up thinking of reading as natural as breathing and books unbelievably powerful in shaping perspectives (观点) by creating worlds we could step into, take part in and live in.

    With this unshakable belief. I, at fourteen, decided to become a writer. Here too, reading became useful. Every with writer starts off knowing that he has something to say, but being unable to find the right ways to say it. He has to find his own voice by reading widely and discovering which parts of the writers he agrees or disagrees with, or agrees with so strongly that it reshapes his own world. He cannot write without loving to read, because only through reading other people's writing can one discover what works, what doesn't and, in the end, together with lots of practice, what voice he has.

    Now I am in college，and have come to realize how important it is to read fiction (文学作品). As a law student, my reading is in fact limited to subject matter — the volume (量) of what I have to read for classes every week means there is little time to read anything else. Such reading made it clearer to me that I live in a very small part in this great place called life. Reading fiction reminds me that there is life beyond my own. It allows me to travel across the high seas and along the Silk Road，all from the comfort of my own armchair, to experience, though secondhand, exciting experiences that I wouldn't necessarily be able to have in my lifetime.

    Most American students go to traditional public schools. There are about 88,000 public schools all over the US. Some students attend about 3,000 independent public schools called charter schools.

    Charter schools are self­governing. Private companies operate some charter schools. They are similar in some ways to traditional public schools. They receive tax just as other public schools do. Charter schools must prove to local or state governments that their students are learning. These governments provide the schools with the agreement called a charter that permits them to operate.

    Charter schools are different because they do not have to obey most laws governing traditional public schools. Local, state or federal governments cannot tell them what to teach. Each school can choose its own goals and decide the ways it wants to reach them. Class size is usually smaller than in traditional public schools.

    Governments strongly support charter schools as a way to re­organize public schools that are failing to educate students. But some education agencies and unions oppose charter schools. One teachers' union has just made public the results of the first national study comparing the progress of students in traditional schools and charter schools.

    The American Federation of Teachers criticized the government's delay in releasing the results of the study, which is called the National Assessment of Educational Progress. Union education experts say the study shows that charter school students performed worse in math and reading tests than students in regular public schools.

    Some experts say the study is not a fair look at charter schools because students in those schools have more problems than students in traditional schools. Other education experts say the study results should make charter school officials demand more student progress.

    On Saturday evening, CCTV showed a computer-generated image of the Chang'e 3 lander's path as it approached the surface of the moon, saying that during the landing period it needed to have no contact with Earth. As it was just hundreds of meters away the lander's camera broadcast images of the moon's surface.

    The Chang'e 3's solar panels, which are used to absorb sunlight to generate power, opened soon after the landing. The mission blasted off (发射) from southwest China on Dec. 2 on a Long March-3B carrier rocket. It is named after a mythical Chinese goddess of the moon and the “Yutu” rover vehicle, or “Jade Rabbit” in English, afternoon the goddess' pet.

    China's military-backed space program has made much progress in a relatively short time, although it is behind the United States and Russia in technology and experience. China sent its first astronaut into space in 2003, becoming the third nation after Russia and the United States to achieve manned space travel independently. In 2006, it sent its first probe (探测器) to the moon. China plans to open a space station around 2020 and send an astronaut to the moon after that.

    “They are taking their time with getting to know about how to fly humans into space, how to build space stations, how to explore the solar system, especially the moon and Mars. They are making big advancements, and I think over the next 10-20 years they'll certainly be matching Russia and America in this area and maybe overtaking them in some areas.”

    Most groups of plants and animals are richer in species and more plentiful near the equator. In the ocean, that holds true for cold-blooded predators(掠食者). But warm-blooded predators are more diverse toward the poles and noticeably missing from several warm hot spots. Why?

    John Grady, an ecologist, and his team considered the possibility—warm-blooded animals need a lot to fuel their metabolism(新陈代谢). Perhaps colder waters are just richer in small fish? But they found that at higher, colder places, there isn't actually much more food around. It's more that warm-blooded animals are eating a much bigger share of it than their cold-blooded competitors.

    The real explanation is simple. An animal's speed, swiftness, and intelligence depend on its metabolism, which in turn depends on its temperature. Since birds and mammals can keep heating their bodies in icy conditions, they remain fast and attentive. By contrast, the fish they hunt become slower and duller. At some tipping point of temperature, seals, dolphins, and penguins start out swimming their prey(猎物). They become more likely to come upon targets and outpace the cold-blooded predators of their own.

    In Grady's words, "Warm-bodied predators are favoured where preys are slow, stupid and cold." That's why sharks and other predatory fish dominate near the equator, but colder waters are the kingdom of whales and seals. By keeping food to themselves in the poles, these creatures can then specialize on specific types of prey, which makes them more likely to split into separate species. The killer whales of the North Pacific, for example, include mammal-eating transients and fish-eating, year-round residents.

    But the world is changing. It's likely that the surface of the oceans will warm by 2 to 3℃ within this century. Grady's team estimates that every time the ocean's surface warms by 1℃, populations of sea mammals will fall by 12%, and populations of seals and sea lions will fall by 24%.

    But "predictions are hard," Donna Hauser from the University of Alaska Fairbanks notes. "Polar bears are losers of a warming world, but some populations are still doing well. Some groups of whales have changed the timing of their migrations; others are hunting in deeper, colder waters. These changes might make sea mammals more adaptable to changing climates. Maybe they just need to find the places where fish remain slow, stupid and cold."

    How's your happiness quotient (指数)? Science tells us that if you want to increase your "happiness quotient" every day, it's important to take time and accept the present blessings (恩赐) in your life.

    I wanted to share a moment of feeling about some of my blessings and what's in my life to be grateful for as Thanksgiving approaches.

    One of our family traditions at our Thanksgiving meal is to go around the table and to let each one share something we're especially thankful for.

    I'm going to recite lots of things, including that I'm grateful for my health, my loving husband, and the wonderful relationship we share. My husband joins me for 3-mile walk to start our day. The exercise habit keeps our moods in check and the ups and downs of life easier to manage. We talk as we walk, sharing ideas, worries and good feelings too. Sometimes we argue a little until we figure out what to do. We always come up with something. What a blessing that is!

    It is so much to be grateful for. I feel I am the luckiest woman alive. It's my wish for you that you'll be able to spot something in your life. I hope yet you will savor (体味) and appreciate it.

    Many of us spend the holiday with our aging parents or other loved ones. In my work at AgthgParents.com, we just reminded everyone that you never know if there will be another Thanksgiving with these loved ones. We can't take the day for granted. Just be in the moment. We suggest that you verbally give thanks to your parents, no matter what conditions your aging parents may be in now. Do what you can to be tuned in to what you need as well as what your family needs.
