Avatar has become the most successful movie in 2009. It is about a soldier whose mind is set into the body of a giant blue alien. He was sent to a dangerous planet called Pandora. His mission（使命） is to find a rare mineral（矿物质）. The mineral is the key to solve the earth's energy crisis(危机).

    According to the latest figures（数字）, Avatar has become the fastest film ever to make more than 1 billion dollars in ticket sales around the world. When it had been shown in cinemas for several days, it became the most popular film ever made.

    Avatar knocked the movie Titanic off the international release top spot. But Titanic's director James Cameron probably won't be too upset, because Avatar is directed by him as well! Before Avatar was filmed, the best selling film ever was Titanic.

    James Cameron decided to make Avatar in 1999. However, the means（方法）to realize his vision（影像画面） did not exist yet. In 2002, The Lord of the' Rings: The Two Towers made him believe that CGI (电脑影像合成) effects had progressed enough to make this film. After several years of production, the 3D spectacular Avatar successfully showed us a fully immersive experience.

    If you like texting and are trying to lose weight, a new study found that using texting(发短信) to track diet and exercise habits may help you lose weight.

    Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are using it to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.

    Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.

    The study included 26 obese/fat women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (反馈) and tips.

    Every morning, the women received a text from an automated system that said, “Please text yesterday's personal information of steps you walked and how many sugary drinks you had.” Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.

    After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.

    “Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior,” Dori Steinberg, who was responsible for this research, said.

    Steinberg said, “Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cell phone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time.”

    Reader: For six years, I've run an office that has two employees: me and my boss. He used to be so appreciative that I didn't mind doing a little extra, but about two months ago, he started being rude and demanding. Now he even yells when I don't have time to bring his favorite wine to his home after work.

    This change started when we met a wealthy new customer, who is a huge jerk (古怪的人) — my boss's new behavior is just like his.

    My boss is a good man; he and his family have treated me like a little sister. Is there a good way to discuss this with him?

    Karla: Sounds like your new customer has set a bad example to your boss. You need to remind your boss that you're in his corner— but you're not his slave. My suggestions are as follows.

Start with a simple question in a calm moment: "Is everything okay?"

State the truth: "Until recently, I've felt like a valued teammate. But our relationship has become tense. Your expectations of me seem to have changed. Although I used to do occasional personal businesses for you as a favor, now it seems expected."

Draw your lines: "If you think my job description needs to change or my performance is not good enough, let's discuss that. Otherwise, I need you to stop yelling at me and to respect my personal time."

Ideally, you'll get an apology and a promise to do better. After that, it's a matter of reinforcement (加强) . If he starts yelling, look at him with a calm expression. After he cools down, restate his request and add, "Is that correct?" For the unreasonable request, such as fetching his favorite wine after work: "I'm afraid I can't take care of that for you." If he keeps acting like a jerk, there are bosses out there who will better respect your time and talent.

    The last time I visited my eighty­three­year­old mother­in­law, I asked how she was feeling. It's a valid question. She has, after all, had two knee replacements and a liver transplant. She moves slowly to avoid another fall.

    But she hasn't stopped moving. She and my father­in­law attended their first Jimmy Buffet concert this summer. Here's the thing about my in­laws: They never say no to an invitation or a new adventure. If they can make it work, they're willing to try just about anything. When we need them to come to stay with the kids, we have to get on their calendars far in advance.

When asked how she was feeling, my motherinlaw responded, "Well, everything hurts every day. But you know what I've discovered? It doesn't hurt to smile. So that's what I've decided to do... smile at everyone I see. I may not be able to do all the things I used to do, but I can at least brighten someone's day."

    It is such simple wisdom. Moving the focus from what we don't have and from what we've lost to what we can offer others is the difference between living in the dark and radiating light. They inspire us daily.

    The key to a life worth living, I think, is to change our views. You don't have to make great changes. Sometimes change looks similar to everyday kindness. Sometimes change begins with holding the door for a mother with an armful of groceries.

    In theory, the butterfly effect says that the smallest breeze(微风) from a butterfly's wing can change the path of a hurricane halfway. Imagine, then, the possibilities that exist within a single smile.

    Family fights are never pleasant. Whether you are dealing with a loud sister or a stubborn mom or dad, the situation can be bad. At least that's what we have learned to expect.

    What if it could be different? What if family fights and conflicts could be turned into opportunities to become closer? What if problems could be solved with everyone walking away feeling more deeply cared for and loved?

    Family fighting is, on one level, about power. Someone is telling someone else what to do. In a short moment, emotions can be brought out and the fight is on. You can go down that old road or you can try something different.

    In any fight, you have a need to be listened to and understood. People raise their voices and shout at each other because they're not being listened to. It's totally unconscious. You want your mom or dad to listen and understand. But you always seems to forget the person you're fighting with has the same need to be listened to. So if you can put aside your need for a few minutes, the situation will change quickly. Give the other person some time to express his or her feelings, and you will earn your turn to be listened to.

    And while you are listening, you have to listen for the right information. The best way to do this in emotional situations is to forget most of the words because many people can't express what they are feeling with words alone, especially when they are upset.

    But if the situation starts to get out of hand, it would be wise to just calm down and leave the problem until later because many fights happen at the wrong time. The situation will die down quickly, usually in less than 30 seconds. You can either move on to problem solving or reach an agreement to work on it at a better time.

    This way, everyone will feel respected and listened to, even when there is conflict. Emotions will be understood and respected, and it will bring your family closer together.

Unhealthy health care bills, long emergency-room waits and inability to find a primary care physician just scratch the surface of the problems that patients face daily.

Primary care should be the backbone of any health care system. Countries with appropriate primary care resources score highly when it comes to health outcomes and costs. The U.S. takes the opposite approach by emphasizing the specialists rather than the primary care physician.

A recent study analyzed the providers who treat Medicare Beneficiaries(老年医保受惠人). The startling finding was that the average Medicare patient saw a total of seven doctors — two primary care physicians and five specialists — in a given year. Contrary to popular belief, the more physicians taking care of you don't guarantee better care. Actually increasing breakup of care results in a corresponding rise in costs and medical errors.

How did we let primary care slip so far? The key is how doctors are paid. Most physicians are paid whenever they perform a medical service. The more a physician does, regardless of quality or outcome, the better he's reimbursed (返还费用). Moreover, the amount of a physician receives leans heavily toward medical or surgical procedures. A specialist who performs a procedure in a 30-minute visit can be paid three times more than a primary care physician using that same 30 minutes to discuss a patient's disease. Combine this fact with annual government threats to indiscriminately cut reimbursements, physicians are faced with no choice but to increase quantity to boost income.

Primary care physicians who refuse to compromise quality are either driven out of business or to cash-only practices, further contributing to the decline of primary care.

Medical students are not blind to this scenario. They see how heavily the reimbursement deck is stacked against primary care. The recent numbers show that since 1997, newly graduated U.S. medical students who choose primary care as a career have declined by 50%. This trend results in emergency rooms being overwhelmed with patients without regular doctors.

How do we fix this problem?

It starts with reforming the physician reimbursement system. Remove the pressure for primary care physicians to squeeze in more patients per hour, and reward them for optimally managing their diseases and practicing evidence-based medicine. Make primary care more attractive food to medical students by forgiving students loans for those who choose primary care as a career and harmonizing the marked difference between specialist and primary care physician salaries.

We're at the point where primary care is needed more than ever. Within a few years, the first wave of 76 million Baby Boomers will become qualified for Medicare. Patients older than 85, who need chronic care most, will rise by 50% this decade.

Who will be there to treat  them？
