Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then,many scientists have thought that our actions do make a difference. In 1997,the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions(排放) from 2008to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims tolimit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.

    I was living a life in my screen and hardly noticed what was around me. So when my friends invited me to go camping for a long weekend without the cell service, I thought this was exactly what I needed. Here's how keeping away from my phone for 48 hours changed me.

    I realized my bedtime routine was usually centered on one thing: my phone. Right before I went to sleep, I browsed through news websites and checked my emails. When I woke up in the middle of the night, I did the same thing. The problem with this was I felt anxious every night. I felt free without my phone at that weekend camp. I felt asleep listening to the sound of crickets.

    When I had my phone, I was always checking the time and thinking of future plans. My thought was: “Who's going to text me now? What will I do next?” Without my phone, I truly savored what I was doing in the moment, sitting by the river, riding a bike, or singing the old songs. There was no need to rush through any of it. I listened to what my body wanted instead of what my phone was telling me to do.

    You know that moment when you're hanging out with a group of people and no one has anything to say? The typical response: Everyone immediately pulls out their phones. So what did we do without a phone to avoid embarrassing silences? We actually talked to each other. Instead of burying our faces in our screens, we looked one another in the eye, had a moment of pure human connection and then continued talking. And you know what? People actually listened.

    So, now what? Now I'm back to the real world.

    The Boy Made It!  One Sunday, Nicholas,a teenager, went skiing at Sugarloaf Mountain in Maine．In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area．Unable to see far,he accidentally turned off the path．Before he knew it,Nicholas was lost,all alone!He didn't have food,water,a phone,or other supplies．He was getting colder by the minute．

    Nicholas had no idea where he was．He tried not to panic．He thought about all of the survival shows he had watched on TV．It was time to put the tips he had learned to use．

    He decided to stop skiing．There was a better chance of someone finding him if he stayed put．The first thing he did was to find shelter from the freezing wind and snow．If he didn't,his body temperature would get very low,which could quickly kill him．

    Using his skis,Nicholas built a snow cave．He gathered a huge mass of snow and dug out a hole in the middle．Then he piled branches on top of himself,like a blanket,to stay as warm as he could．

    By that evening,Nicholas was really hungry．He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water．Not knowing how much longer he could last,Nicholas did the only thing he could—he huddled(蜷缩)in his cave and slept．

    The next day,Nicholas went out to look for help,but he couldn't find anyone．He followed his tracks and returned to the snow cave,because without shelter,he could die that night．On Tuesday,Nicholas went out again to find help．He had walked for about a mile when a volunteer searcher found him．After two days stuck in the snow,Nicholas was saved．

Nicholas might not have survived this snowstorm had it not been for TV．He had often watched Grylls' survival show —-Man vs．Wild． That's where he learned the tips that saved his life．In each episode(一期节目) of Man vs．Wild, Grylls is abandoned in a wild area and has to find his way out．

    When Grylls heard about Nicholas' amazing deeds,he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive．

    It's a sadness shared by many business start-ups: why did my company fail, while so many others seem to be profiting from the “golden age of entrepreneurship (创业精神）”？

    Some people argue that opportunities and good fortune are the secrets to success. But Innovation Works CEO Kaifu Lee believes that entrepreneurs need to have certain qualities to help them face the difficulties of starting a business. At a recent LinkedIn conference, Lee mentioned some of these qualities.

    “Even though we're now in a golden period for innovation and start-ups, not everyone is meant to be an entrepre- neur. Entrepreneurs share the same qualities — they are confident, communicative and focused. They don't fear losing, and they are good at learning,”he said.

    Lee explained that he often meets young people who are irresolute about setting up a business.“ If that's the case for you then don't do so,” he said at the conference. The bottom line, he said, is that entrepreneurs should be determined and passionate.

    Passion is vital to entrepreneurs since it typically relates to self-motivation, according to Li Jun, 26, founder of Wuhan Lushenglin Plant Wall Co Ltd. “Entrepreneurs often need to work around the clock. It's easier for people to put up with the difficult schedule if they're passionate about what they're doing,” he said.

    Entrepreneurs are also generally thought of as risk-takers. But Yu Xiuhong, general secretary of the Bright China foundation, warns that young entrepreneurs should not take too many risks. “Successful entrepreneurs rarely take risks blindly or jump at opportunities others avoid. Before launching a business, it's advisable to do market research, evaluate yourself and your opponents,” she said.

    Also she advises that young people thoroughly calculate their expenses in advance. Take Li Dongjin as an example, 35-year-old long-term entrepreneur disappeared a week ago after his O2O car washing company failed disastrously. He had gotten an initial investment of 5 million yuan but wasted it all on allowance and publicity.

    You are given many opportunities in life to choose to be a victim or a creator. When you choose to be a victim, the world is a cold and difficult place. “They” did things to you which caused all of your pain and suffering. “They” are wrong and bad, and life is terrible as long as “they” are around. Or you may blame yourself for all your problems, thus internalizing(内化) your victimization. The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others.

    Those who choose to be creators look at life quite differently. They know there are individuals who might like to control their lives, but they don't let this get in the way. They know they have their weaknesses, yet they don't blame themselves when they fail. Whatever happens, they have choice in the matter. They believe their dance with each sacred(神圣的) moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.

    Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims relish (沉溺) in anger, guilt, and other emotions that cause others—and even themselves—to feel like victims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them. Both victims and creators always have choice to determine the direction of their lives.

    In reality, all of us play the victim or the creator at various points in our lives. One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime. Another with the same experience may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life. In every moment and every circumstance, you can choose to have a fuller, richer life by setting a clear intention to transform the victim within, and by inviting into your life the powerful creator that you are.

    Some people will do just about anything to save money. And I am one of them .Take my family's last vacation .It was my six-year-old son's winter break from school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline ,offered us $400 per person in credits to give up our seats and leave the next day .I had meeting in New York, So I had to get back . But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.

    The next day my husband and son were offered more credits to take an even later flight. Yes, I encouraged一okay, ordered-them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?

    Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is some-time thing few of us can afford to pass up.

    I've made living looking for the best deals and exposing (揭露) the worst tricks .I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in. I tell you this because there is no shame in getting your money's worth. I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.
