Charlotte Heffelmire was home in Vienna,Va.,for Thanksgiving break from the Air Force Academy when she saw that her father had gotten stuck under the pickup truck he'd been working on.

    "I was on my back,face up,and I was trying to get some brake lines when apparently the jack（千斤顶）slipped and fell down on me,"her dad,Eric Heffelmire,told WUSA9.Gasoline spilled（溢出）and caught fire,and he knew he was in trouble."I thought they 'd be pulling out a dead body later in the evening."

    After his struggling for 10 minutes,his barefoot teenage daughter came running into the garage."I felt the weight shift,and I said,'You almost got it.'and then it was just UGHHHRRR,and suddenly I'm pulled out,"Eric told NBC4.

    Even Charlotte,120 pounds and 5-foot-6,isn't sure where her power came from."It was some crazy strength, "she told WUSA9.

    Realizing the burning truck could set her house on fire at any moment,Charlotte jumped into the truck and drove it out of the garage."I didn't want the entire house to explode with the truck,so I started the truck,put it in four-wheel drive,and managed to drive it with three wheels,"she said.

    Then she went inside the house to grab her baby sister and got her grandmother out of the house too."I just did what I had to do,so I don't feel like a big hero or anything,"Charlotte said.Her local fire department,Fairfax County Fire and Rescue,felt differently,awarding her the Citizen Lifesaving Award.

    People are seeking for opportunities that will assist them in reaching their goals. Marketing yourself can be a good choice, which can help you achieve your goals. Though when people talk about marketing, they usually think that this is about producing a sale, it does not necessarily have to be.

    If you are an employee then you want your boss to take your ideas, and if you are on a job hunting then you want to find a good position. So in reality, marketing really leads to sale. So marketing yourself means you are simply “selling” yourself!

    The common problem in marketing yourself is that most people think that it is unpleasant to market themselves. They think that marketing concerns only to a business. Of course, this is absolutely not true. People who want to attain the success they desire must promote themselves.

    Marketing yourself is a useful tool. The better you market yourself, the more opportunities you will have. Marketing yourself does not really mean telling every person how beautiful and wonderful you are. It means letting your prospective employer know that you exist or you can do something better.

    There are actually several different ways of marketing yourself. But there are only two primary ways that you carry out. The first is to find ways to reach out to others and the second is to construct ways in order for the people to find you and make connection with you.

    To reach out and touch the lives of others, you have to be a good person and a good employee. In that way your good reputation will follow naturally. Have a brief and concise message that you can share with others. When you market yourself, you tell people who you are and what you can do for others. Plan well and practice your message.

    In constructing ways for the people to notice and make connection with you, you must be open to them. Communication is a great opportunity to make an impact especially when you market yourself. You also communicate by what you are wearing. Know the appropriate dress code and have plenty of time to decide what you will wear. Just remember to make a great first impression!

    Around three forty-five on a rainy Saturday morning, I was woken up by the sound of my pager(呼机) beeping. As a volunteer firefighter and emergency medical technician, I can never count on a full night of sleep. I pulled myself out of bed and went toward the desk to grab my radio. Our crew was being sent to a nearby home where a man was in cardiac arrest (心脏骤停). We found the man lying on the kitchen floor with his wife beside him. We rushed the patient to the hospital, but despite our efforts, we were unable to save his life.

    In my line of life, I rarely get any recognition from the patients we treat, or from their loved ones. But that night, a man's wife approached us, and through her tears, whispered, “Thank you.” Then she hugged each of us. She knew we answered her late-night call for help, even though the ending was not positive.

    There is something deeply rewarding about helping people in these circumstances. Sometimes, I'm able to make their worst day a bit better: like seeing the tears of an injured child turn into a smile when I gave him an interesting toy; or watching a terrified mother's screams turn into tears of joy when she realized her baby was going to be fine.

    Experiences like these allow me to see the impact my work has on others. At the same time, I also know the effect it has had on my own life. As a teenager, I felt awkward when my dad hugged me and said, “ I love you, my dear son.” I was equally uncomfortable and responded, “I love you.” But then I imagined him lying on the kitchen floor that rainy night and realized that my opportunity to say those three words could—at any moment—be taken away forever. Now, I extremely treasure the moment when my father says those three words to me. I've learned to appreciate every relationship I have, to tell people I care about them, and to never take anything in life for granted.

    As the days get shorter and the chilly weather rolls in, we all want to curl up in a blanket and hibernate until spring rolls around. But making time to get outside in the sun, even when it's cold out, could have bigger mood benefits than you might realize.

    While the link between sunshine and mental health is nothing new, new research from Brigham Young University (BYU) has shown that the association may be even stronger than previously realized. It finds that sunlight exposure is by far the greatest weather-related factor determining mental health outcomes. In other words: more sunshine, more happiness.

    For the study, a psychologist, a physicist and a statistician from BYU teamed up to compare daily environmental data from the university's Physics and Astronomy Weather Station with emotional health data archived by day for 16,452 adult therapy patients who were being treated at the BYU Counseling and Psychological Services Center.

    Exposure to sunlight is a significant factor in seasonal affective disorder. Research has shown that the brain produces more of the feel-good neurotransmitter serotonin on sunny days than it does on darker days. What's more, lack of sunlight is linked with lower vitamin D levels, which in turn has been correlated with depression and low energy.

    If you're getting enough sun, your emotions should remain relatively stable, the researchers found. But as the amount of sunlight in the day is reduced, levels of emotional pain can soar. Other weather variables including temperature, pollution and rain were not found to have an impact on mental health.

    “We were surprised that many of the weather and pollution variables we included in the study were not significantly correlated with clients' scores on the distress measure once we had accounted for suntime," Dr. Mark Beecher, a professor of psychology at the university and the study's lead author, told The Huffington Post. “People tend to associate rainy days, pollution, and other meteorological phenomena with sadness or depression, but we did not find that.”

    Memory, they say, is a matter of practice and exercise. If you have the wish and really make a conscious(自觉的) effort, then you can quite easily improve your ability to remember things. But even if you are successful, there are times when your memory seems to play tricks on you.

    Sometimes you remember things that really did not happen. One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remember locking it carefully the night before.

    Memory "tricks" work the other way as well. Once in a while you remember not doing something, and then find out that you did. One day last month, for example, I was sitting in a barber shop waiting for my turn to get a haircut, and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.

    We always seem to find something funny and amusing in incidents caused by people's forgetfulness or absent-mindedness. Stories about absent-minded professors have been told for years, and we never get tired of hearing new ones. Unfortunately, however, absent-mindedness is not always funny. There are times when "tricks" of our memory can cause us great trouble.

    When an ice cube melts, it creates a puddle (水坑). When an ice sheet (冰盖)melts, it raises sea levels. It sounds simple, but scientists have debated for decades whether both the Antarctic and Greenland ice sheets actually were shrinking, and how much that melting contributed to rising sea levels.

    Now, a new study has provided the best evidence of how the polar ice sheets are responding to our warming world. In the study, an international team of scientists looked at 20 years of' data in the ice sheets collected by 10 satellite missions. The team's conclusion: The Greenland and Antarctic ice sheets both are losing ice overall. The researchers also found that between 1992 and 2011, melt water from those shrinking ice sheets caused sea levels to rise by about 11 millimeters.

    Over the 19 years studied, the Greenland ice sheet lost 2.7 trillion metric tons of ice. The Antarctic ice sheet also shrank by about 1.3 trillion metric tons. Previously, some scientists disagreed whether the Antarctic sheet, the largest mass of ice in the world, was shrinking or growing or neither.

    While the Earth is warming overall, the effect of climate change varies from region to region. Over the last 15 years, for example, scientists have something disagreed over how climate change has affected the polar ice sheets. Many studies found that the sheets lost a lot of ice and that not enough snow fell on the sheets to compensate for the loss. But other studies found that the loss of ice was balanced by the gain in snowfall.

    Richard Alley, a glacier scientist at Penn State University, said that many of those studies looked at different areas, and over different time periods. In addition, the studies didn't all use the satellite data in the same way. Those differences made, it difficult to compare the results.

    The data in the new study matched time periods and areas. The study also combined measurements from kinds of satellites.
