When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie, “ Homeless to Harvard: The Liz Murray Story”, shown in late April.

    Liz Murray，a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that loss became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.

    Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “ What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being. I had only experienced a small part of the society,” she wrote in her book Breaking Night.

    She admitted that she used envy to drive herself on. She used the benefits that come easily to others such as a safe living environment, to encourage herself  that “next to nothing could hold me down”. She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS. “I love my parents so much. They are drug addicts. But I never forget that they loved me all the time.”

    Liz wants moviegoers to come away with the idea that changing your life is “as simple as making a decision”.

    For thousands of years comets have been a mystery to man. They travel across the sky very fast and have a bright “tail” of burning gas. The comet Tempel 1 has an orbit（轨道） far outside the orbit of the furthest planet in our solar system, Pluto. It has been there for 4.6 billion years, 133 million kilometers from Earth. Last week a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the comet every minute before it finally crashed into its surface.

    The space mission to Tempel 1 cost $335 million and was called Deep Impact. The spacecraft was travelling at 37,000 kilometers per hour when it hit the comet and the crash completely destroyed the spacecraft. But before it hit the comet, the spacecraft took some amazing photographs. The last one was a close-up picture which the spacecraft took just 3 seconds before it crashed into the comet.

    “Right now we have lost one spacecraft,” said a delighted NASA engineer. Deep Impact was like a American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion. 

    The spacecraft which crashed into the comet was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the comet and the mothership then photographed the cloud of ice, dust and organic chemicals that rose from the surface of the comet after the crash.

    The crash completely destroyed the spacecraft but nothing really happened to the comet: experts believe that the crash slowed the comet down by no more than 1/10,000 of a millimeter a second.The aim of the mission was to study for the first time the interior of a comet.

    The mothership was 480 km from the explosion and observed the crash and the explosion with instruments for 800 seconds. Seven satellites, including the Hubble space telescope, watched the moment of drama, and over the next day and night about 50 telescopes on Earth were watching the distant comet.

    The first time she saw Bryce Loski, she flipped. The first time he saw Juli Baker, he ran. For six years of living close by, they had played the same game of cat-and-mouse (Juli was the cat; Bryce was the unfortunate mouse).

    For years Juli dreamed of one thing: her first kiss from the boy. Nothing else seemed to matter. But when Juli's favorite sycamore tree is threatened by developers, things begin to change. She begins to see things and places and people in a different light. Things, for years, she thought to be important, become things she can live without; and people she thought to be the center of her universe, become nothing more than a star in a faraway galaxy.

    Things begin changing with Bryce also. It all begins with the eggs…which then cause a domino effect of changes with his relationships with his best friend, his father, the Bakers and, ultimately, Juli.

    I had seen this book on the shelf at bookstores for years, but never bothered to pick it up because it looked to be another book from Jerry Spinelli (not exactly my favorite author in the world) and so, continually, I would walk past it without giving it a second glance. If by chance I had picked it up, I most likely would not have read it, since the summary on the back didn't seem too appealing. It wasn't until a couple of weeks ago that I heard about Flipped the movie. I read an interview with Callan McAuliffe (the actor who portrays Bryce) and thought that Flipped was a romance right up my alley; cute, innocent and as far from Jane Austin as you could get. After reading the interview and a summary of the movie, I found the plot-line to be somewhat appealing and a definite breath of fresh air opposed to the dark material I have been recently reading and writing. I found the book a few days later in a Goodwill bookstore and finished it in three days.

    The story isn't what you would consider deep…it isn't shallow and pointless either…I guess you could say it's the perfect balance of life-lessons and innocence.

    You read about Bryce and Juli (each from their own points of view) and how, throughout six years, their lives and views and opinions change and develop. Flipped is somewhat of a coming of age story about two kids learning to see life from the other's point of view and learning that growing up isn't about staying the same, but changing; changing likes and dislikes; changing friends and crushes and views on family.

Uniquely written, every other chapter showing the same scenes and events, only from the other's point of view, you see how the saying, "Two sides to every story," is true. You are able to see both Juli and Bryce's reasons for doing what they do and saying what they say…not just what the other sees.

    It will be interesting to see how this writing style comes into play in the movie. Overall I thought this story was incredibly cute and light-hearted, although it didn't entirely meet my expectations. Especially the ending. I felt as though it ended quite abruptly and that there was more story that needed to be told.

    But even with that, after having taken a step back and taken my mind off of Flipped, I find the story has stuck with me and stayed in the back of my mind, making me highly anticipate seeing this book turned to a film. I understand why it has been so popular for almost two decades and am looking forward to seeing Flipped on the big screen soon.

    One of the greatest sources of unhappiness, in my experience, is the difficulty we have in accepting things as they are.

    When we see something we don't like, we wish it could be different. We cry out for something better. That may be human nature, or perhaps it's something ingrained(根深蒂固的) in our culture. The root of the unhappiness isn't necessarily that we want things to be different. However, it's that we decided we didn't like it in the first place. We've judged it as bad, rather than saying, "It's not bad or good, and it just is it."

    In one of my books, I said "You should expect people to mess up and expect things to go differently than you planned". Some readers said it's too sorrowful to expect things to go wrong. However, it's only negative if you see it as negative and judge it as bad. Instead, you could accept it as the way the world works and try to understand why that is.

    This can be applied to whatever you do: how other people act at work, how politics works and how depressing the news media can be. Accept these things as they are, and try to understand why they're that way. It will save you a lot of sadness, because you'll no longer say, "Oh. I wish bad things didn't happen!"

    Does it mean you can never change things? Not at all. But change things not because you can't accept things as they are, but because you enjoy the process of changing, learning and growing.

    Can we make this world a better place? You can say that you'll continue to try to do things to help others, to grow as a person, to make a difference in this world. That's the correct path you choose to take, because you enjoy that path. Therefore, when you find yourself judging and wishing for difference, try a different approach: accept, and understand. It might lead to some interesting results.

    Earlier this month, two rock climbers achieved what many thought impossible: They climbed up the 3,000-foot-high Dawn Wall in Yosemite National Park without specialized equipment. Climbing without this equipment is called "free-climbing." Until now, no one had free-climbed to the top of the rock face, which is a part of the mountain EI Capitan.

    EI Capitan, which means "the captain" or "the chief" in Spanish, has always presented a challenge to climbers. But the Dawn Wall, on the mountain^'s southeast face, is a particularly difficult route to the summit (顶峰). It is a rock formation that is both steep and relatively smooth. This makes free-climbing the rock face seem almost impossible.

    About seven years ago, professional climber Tommy Caldwell spotted a possible route up the wall. It took years of planning and preparation, but this month, Caldwell, 36, and his friend Kevin Jorgeson, 30, finally make the climb.

    Free climbers do use ropes and other basic safety equipment to catch them if they fall — and Caldwell and Jorgeson fell often. Before starting their climb, they broke down their route into 32 sections. Each section was based on a rope length called a "pitch." The rope was secured into the rock face to catch the climbers if they fell.

    Caldwell and Jorgeson's goal was to climb the Dawn Wall without returning to the ground. If they fell, they had to start that pitch all over again. The two men started climbing on December 27. They slept in hanging tents, and a team of friends brought them food each day.

    The men had spent years rehearsing (排练) the movements it would take to get through each pitch. They made it through the first half of the climb relatively easily. But halfway up, Jorgeson ran into trouble. In one difficult spot, he fell each time he attempted to climb. After 10 days of trying, Jorgeson finally made it to the next pitch.

    Getting through that troublesome pitch gave both climbers renewed energy. They finished the rest of the climb five days later, on January 14.

    We spend a great amount of time listening to music. Most college students listen to music at least three or four times a week, and more than 50 percent of them go to at least one concert per year.

    According to new research, we may be born liking music, because human beings are born to find certain combinations of sounds attractive. For example, young children can recognize a familiar Song even when its key is changed. Similarly, they respond with more emotions to their mothers' singing than to their mothers' speech. Careful analysis of mothers' child-directed songs indicates that each mother's songs remain stable from one "performance" to the next, and this may encourage children's engagement with the songs.

    Research with adults suggests that music catches our attention by activating(激活) brain pathways that are most suited to processing music than to processing other kinds of sound. Specifically, music appreciation relies on the auditory cortex(听觉皮层) on the right side of the brain, which is specialized to process sound that characterizes music-in contrast to the left auditory cortex, which processes the stop-and-start bursts of sound that characterize speech.

    Although some Psychologists remain skeptical about whether music may have powerful effects on our thinking, a number of studies have shown that listening to music can increase people's spatial reasoning abilities Furthermore, It is clear that music can greatly influence our emotions. Personally significant music activates areas of the brain associated with pleasure and reward, the same areas that are activated by sex and good food.

    Researchers do not agree about how humans' abilities to process and enjoy music have come into being. Anyway, the next time you enjoy listening to a piece of music, remember that the most complex pieces of audio equipment are the ones between your headphones.
