“A good book might clarify something you knew little about, transform your world view, or move you in ways you didn't think possible. The Soul of an Octopus(章鱼)delivers on all three, ”the magazine New Scientist commented.

    After writing about birds, pigs and tigers, US naturalist Sy Montgomery decided to choose these many-footed animals as the subject of her latest book, The Soul of an Octopus: a surprising exploration into the wonder of consciousness.

    “Here is animal with poisonous liquid like a snake，a beak(喙)like a parrot，and ink like an old-fashioned pen. It can weigh as much as a man and extend as long as a car, yet it can pour its baggy; boneless body through an opening the size of all orange. It can change color and shape. It has a tongue covered with teeth. It can taste with its skin.” Montgomery explained to the National Geographic on why octopuses inspired her.

    What Montgomery is able to show in The Soul of an Octopus is that octopuses are creatures who exhibit personality, intelligence and emotion, despite having nervous systems completely different from our own. She uses different experiments to show that they possess consciousness as well as individual personalities. For example, based on her research, she finds out that Octavia, an octopus caught in the wild, is friendly and good at multi-tasking. And Kali, another octopus，who has been living at the New England Aquarium, is playful and loves exploring.

    Montgomery is a good storyteller. Through her study of, and communication with, these extraordinary creatures she shares what she learns from both science and her experiences. Her skillful writing presents facts together with personal description, which makes the book very informative but easy to read.

    In 1869, the Smiley family purchased an area of land about 100 miles north of New York City. Over time, some of their property and much of the surrounding landscape became the Mohonk Preserve, which has since grown to 8,000 acres and attracts visitors and rock climbers.

    But the Mohonk Preserve also has a long scientific legacy. In the 1930s, Dan Smiley, a descendent of the original owners, began keeping track of the plants and animals that lived in the area.

    Megan Napoli is a research ecologist with the Mohonk Preserve in New York. She thinks Smiley's efforts produced a rare long-term data set of observations, which is useful for studying the impacts of climate change. For instance, other research has shown that songbirds are migrating north earlier and earlier in the spring.

    It's important for the birds to arrive at the proper time in the spring, because they need to time their arrival with the insect emergence. So they need to be here to establish their nesting sites, lay their eggs. Once the eggs hatch, they have their baby birds, so they need to time it when the insects are most abundant.

    Napoli has begun analyzing about 76,000 observations of songbird migration dates collected by Smiley and his team to see if they, too, show that climate change has altered the timing of migrations. Her results suggest that they do.

    Napoli found that short-distance migrants that spend their winters in the southern U. S. now arrive an average of eleven days earlier than they did in the 1930s. Long-distance migrants that overwinter in the tropics arrive roughly a week earlier. Napoli presented her results at a recent Ecological Society of America meeting in Portland, Oregon.

    Meanwhile, who knows how many other long-term, personal data collections like Smiley's are out there, waiting to be discovered and to help improve official attempts to track the planet's changes.

    If you want to get the most out of the study of a language, you must also read for pleasure: novels, plays, travel books, and so on. And in reading books of this kind the important thing is to get on with reading; to try to grasp what the writer is going to tell you in the book as a whole. This is impossible if you stop and think over the meaning of every single word which happens to be unfamiliar. You can not enjoy a story if you stop half a dozen times on every page in order to look up words in the dictionary. You may even prevent yourself from understanding the story as a whole by doing this.

    When you are reading books of this kind, therefore, you will usually have to rely mainly on the context to help you. If you meet an unfamiliar word, do not let it take too much of your attention from the main thread(主线) of the story. In all probability you will meet the same word again a few pages later on in a slightly different context, and each time you see it that your understanding of it will become more exact.

    I was once told, “You are wasting your time on a career that will give you no money or comfort”.

    I explored my interests for years and finally decided to be a journalist. However, I'm still influenced by others' arguments: print publications are being replaced by web versions where content is updated nearly every time you refresh the browser. But I hold onto my decision. Why? For the simple, yet powerful reason that it makes me happy in a way that no amount of money ever could.

    Rarely have I found others who think like this, and I find it very disappointing when I hear students trying to design their lives on the basis of factors (因素) other than keeping to their passions and interests.

    Factor number one is parents. They certainly have a right to be a part in their children's lives, but sometimes their words create more stress than encouragement. Instead of trying to make their children happy, as their original purpose may have been, parents can end up limiting their children's dreams and desires until nothing remains but the hard seeds of a cruel reality.

    The second factor is money. I had a conversation with my college friend one afternoon, which explains this point.

    “What happened?” I asked him after he said he had changed his major. “I thought you wanted to be a photographer.”

    “I do,” he said, “But there is no money in it. Don't worry,” he added, probably feeling my worry. “I'm happy where I am.” I was ready to believe that, but as we kept on talking, he continuously interrupted me to point out the beauty of this view and that view, saying he wished he had taken his camera with him.

    Naturally, we cannot predict where we will end up with our choices. Our ideas and plans could change as we progress. However, at this stage in our lives when so many voices are telling us who we should be, we need to value our individual dreams, not to abandon them, because they may be the only things left that tell us who we are.

    Steven Spielberg's 2002 science-fiction thriller Minority Report produced a world where computers could read minds and predict the future. It seemed fanciful at the time, but fantasy is edging closer to fact.

    On Jan 31, a team of scientists at UC Berkeley, led by Robert Knight programmed computers to decode (破译) brain waves and replay them as words. Five months earlier, another group of Berkeley scientists showed their colleagues short movies and used computers to play back in color what people saw.

    These experiments are a big advance from 2006, when a French scientist first replayed images from a human mind, a black-and-white checkerboard pattern. The possibilities are great: a disabled person could" speak"; doctors could access the mind of a patient who fainted; you could rewatch your dreams on an iPad. There are, of course, equally dark side, such as the involuntary take out of information from the brain.

    In spite of these breakthroughs, Jack Gallant, the neuroscientist who led the first Berkeley team, says current technology for decoding brain activity is still "relatively primitive". The field is held back by its poor machinery, in particular the FMRI.

    "Eventually," says Gallant, "someone will invent a decoding machine you can wear as a hat." Such an advance into the human mind, he says, might take 30 years.

    Still, the recent advances at Berkeley offer small answers, which scientists can use to begin unlocking the secrets of memory and consciousness.

    Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics. But sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you should build a positive self-image and learn to love yourself.

    Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about US. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

    The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.

    It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.

    The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat (拍) yourself on the back, you'll know you're well on your way. Good luck!
