Science has a lot of uses. It can reveal (揭示) laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation (诱惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal, The Hidden Sources of Love, Character, and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.

    Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren't?

    To answer these questions, Brooks surveys a wide range of subjects. Because of this, you might expect the book to cover a variety of facts. But Brooks has structured his book in an unusual, and perhaps unfortunate way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention. So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.

    On the whole, Brooks's story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks's attempt to translate his tale into science.

    Even if trees cannot walk, they are still on the move.

    In parts of the Arctic, entire forests are moving northward. Across the Arctic, temperatures are rising faster than anywhere else in the world. As that happens, the tree line that marks where forests stop and the treeless tundra(冻土地带) starts has been shifting northward. Trees growing along the tree line must protect themselves from the cold wind. To do this, plants tend to grow horizontal(水平的) branches low to the ground. The energy it takes for trees to grow this way means they don't have enough energy to make seeds.

    But as Earth's climate has been warming, trees no longer have to just grow horizontally. Many can instead grow up toward the sky. This takes less energy. And with all the leftover energy. these trees have started producing more seeds. This happens especially in places where the white spruce(白云杉) grows.

    White spruce, which is a North American tree, is quite able to produce a lot of seeds, which can move long distances in the wind. When wind-blown seeds end up on the tundra beyond the tree line, they eventually can sprout(发芽) new trees. This explains how a forest can move. Of course, the process would work only if the tundra were warm enough. But in recent years, the whole planet has been warming.

    New trees will provide shelters for some snow, keeping the sun's rays from making the white surface disappear. Instead, the trees absorb the sun's heat. This warms the surrounding air. The extra warmth encourages even more trees to produce seeds. That further boosts a forest's ability to expand. In addition, more trees will trap more snow, preventing much of it from being blown away. Snow can trap heat in the soil below, which encourages trees to grow. The recent rise of temperature has helped more trees grow. The recent rise of temperatures has helped more trees grow past the tree line. People worry about impacts on the animals that depend on frozen conditions for food and shelter.

The American Bystander

    On a humid subway ride into work a few days ago, a woman on the other end of my car had a seizure (病情突然发作). All of a sudden, I heard her let out a painful sigh as she collapsed. For several minutes, the train continued down the track, and everyone in the car just stared at the woman. Finally, at the next stop a man informed the operator of what had happened and called 911. Luckily the woman came to herself as the EMTs carried her off the train. Ever since, I've been puzzled by the same question — why didn't anyone do anything? And more importantly, why didn't I do anything?

    We've learned about the commonly referenced bystander effect—a psychological phenomenon in which individuals will avoid offering help to a person in need when other people are present. The bystander effect is attributed to two different psychological processes: social influence—individuals in a group will monitor and imitate other group members' behavior—and shift of responsibility—individuals will cease to help because they believe that someone else will.

    Even though most people probably haven't witnessed a woman having a seizure on the subway, I'm sure if asked, anyone could think of a time when they could have helped and simply didn't. In fact, I know that we have all experienced the bystander effect, because I believe it is one of American society's most common headaches.

    Anyone who follows the news can tell you that most of what we hear or read about these days is another death or another hate crime committed right in our own country. Consider the most recent theatre shooting in Nashville. The headlines read Another Theatre Shooting, Gunman is dead. When we read that headline or heard it on the news, most of us just acknowledged how sad it was, then told ourselves that there is nothing we can do to help and assumed that someone else would.

    If America is just one large group of witnesses, all while telling ourselves that someone else most certainly will step in, how can we hope to shake the hold of this social psychological spell? The solution lies solely within us, to know the difference between doing what is justifiable and doing what is right, helping those in need when we have the means and opportunity to do so.

    I want to be like the man on the subway who told the operator about the woman's seizure, because as soon as he did, people followed suit and offered help. We have the power to choose whether to justify passivity or actively decide to do the right thing, and as a society I believe we ought to break free from our psychological tendency to just stand by.

The Power of Sound

The music of world-famous guitarist Gabriel Ayala can make you cheer or cry depending on the chords（弦）. As the winner of numerous musical honors, he said," I love the power of sound.

    He was also recently named Native American Music Awards Artist of the Year and he played at the inauguration（就职典礼）of President Barack Obama.

"My concerts are a journey for both my audiences and myself," he says. "Feelings and emotions are all over the board and I am the tool trying to convey those feelings, trying to paint a visual picture through chord changes. Sound conveys power, whether it's a well-performed craze or the wind blowing through the trees. Music isn't just a pretty melody also it's a visual performance that captures moments in life and puts them to music."

    Ayala also shares his gift with kids As a teacher with a master's degree he serves as an advocate（提倡者）for youth education by being a role model. He practices the philosophy of honoring elders, respecting women and loving children. He delivers a message lo youth that they can become whatever they dream of.

The music man has recently launched a non-profit foundation to work more closely with youngsters "I've been blessed in both my career and life and feel I need to give back to pay my respect and hanks for the gift I have owned and I can do that through music," he says.

    One of his experiences in giving back involved a high school class of some 200, which included a special needs group. I used my guitar as a tool to capture their interest and once I began playing, the whole behaviors of the class changed in a positive way. This was especially so for one of the disabled students whose hands would not allow him to even hold my costly guitar.

    When I put the valuable guitar in his lap and he started beating the heck out of it as hard as he could, there wasn't a dry eye in the house. That's the real reason I play music, not for fame or fortune but because music has the power to truly heal. The look on that boy's face was priceless.

    I left university with a good degree in English Literature, but no sense of what I wanted to do. Over the next six years, __________ just trying to earn an income. I tried journalism, but I didn't think I was any good, then finance, which I hated. Finally, I got a job as a rights assistant at a famous publisher. I loved working with books, although the job that I did was dull.

    I had enough savings to take a year off work, and I decided to try to satisfy a deep-down wish to write a novel. Attending a Novel Writing MA course gave me the structure I needed to write my first 55,000 words.

    It takes confidence to make a new start — there's a dark period in-between where you're neither one thing nor the other. You're out for dinner and people ask what you do, and you're too ashamed to say, "Well, I'm writing a novel, but I'm not quite sure if I'm going to get there." My confidence dived. Believing my novel could not be published.

    I put it aside.

    Then I met an agent(代理商)who said I should send my novel out to agents. So, I did and, to my surprise, got some wonderful feedback. I felt a little hope that I might actually become a published writer and, after signing with an agent, I finished the second half of the novel.

The next problem was finding a publisher. After two-and-a-half years of no income, just waiting and wondering, a publisher offered me a book deal — that publisher turned out to be the one I once worked for.

    It feels like an unbelievable stroke of luck — of fate, really. When you set out to do something different, there's no end in sight, so to find myself in a position where I now have my own name on a contract of the publisher — to be a published writer — is unbelievably rewarding.

    On March 2, at the meeting held ahead of the yearly session of the CPPCC National Committee(全国政协大会), interpreter(口译员)Yao Mengyao caught the attention of many with her "quick reaction and correct translation," Xinhua noted,

    Yao began her studies in English in primary school where she would listen to English tapes. She ofen spoke to her teacher about English-related topics that were not limited to the ones in her textbooks, "They were always very professional uncommon topics, "said Yao's senior school teacher Shen Yingzi,

    Like Yao, Zhang Lu is a regular interpreter for China's top leaders, including Premier Li Keqing and former Premier Wen Jiabao Her effortless but on-point translations of ancient poems mentioned by former Premier Wen won praise.

    So how do interpreters reach their top positions?

    The reason for their success is largely hard work. Other than when they go out on visits with Chinese leaders, the interpreters follow a very strict schedule. Zhang called this schedule"an unshakable plan". They listen to foreign media such as BBC, VOA or CNN through TV or radio for their training.

    It is reported that a month before the two sessions(两会), the interpreters get notice of the spokesperson they are going to interpret for. They then make full use of this month to prepare themselves. They try to predict the questions that might be asked and consider the sayings the spokesperson might use when they answer the questions.

    In truth, there is no secret to their success: It's all a matter of skill and hard work.
