Do you want to be productive（富有成效的）at work or at home? Here's what you should do.

Turn off television

    I used to tell myself that I needed a break. So, when the kids slept I turned on the cable and watched whatever program that caught my fancy. Often, I found myself not watching, just channel-surfing. And I didn't end up watching a full program. I decided one day to just give up on TV as it made me sleep late and woke up exhausted（疲惫的）.

    If you want to be productive, cut off TV. You are better off reading a book. Without TV, I have managed to finish many books which I have bought but never read.

Limit Internet Use

    The other big distraction that can make you sleep late is the Internet. Probably because you will be checking your emails, updating your blog, watching YouTube, etc. Try limiting the use of it at home, or switch it to the morning session.

    Nowadays, I check all my personal emails early in the morning. When I get into work, I find myself less tempted to check personal emails.

Know Your Priorities(优先考虑的事)

    Really, it is all about the choices you make and the priorities you have. If you know it is competitive out there in the world, how can you be a better worker than the person who is also aiming for the position above you?

Rest Early, Rise Early

    You want to be productive? Rise early, read more books, have more energy, be more focused and set standards for others to catch up. It's as simple as that.

    Bees and other pollinators（传粉者）  use smells to track down fresh flowers. Air pollutants can weaken those scents（气味）.  Scientists had worried this might make it harder for some pollinators to find a meal.

    Many animals help pollinate plants. Species that do this include bees, butterflies, etc. But for many reasons, the pollinators available to help plants in this way are decreasing. Scientists think a loss of habitat（栖息地）can be one factor. Diseases and exposure to poisonous chemicals also count.

    Jose Fuentes points to air pollution as another possible factor. He's an atmospheric scientist at Pennsylvania State University. In an earlier study, he showed some air pollutants could weaken or destroy scents emitted(发出)by flowers.

    Searching for a meal leaves pollinators out in the open and at risk of becoming other animal's lunch. And any time spent hunting food is time away from their duties back home, like protecting a hive（蜂巢）or nest, explains T'ai Roulston. He's an insect biologist at Virginia University. Roulston worked with Fuentes on the new study.

    In the study, the researchers focused on five kinds of representative scent molecules(分子)plants emit. One molecule they looked at, for example, is called beta-myrcene. Many flowers give off this chemical into the air.  Normally, this gas can travel some 800 meters from its flower source. But in polluted air, this same molecule could travel only half as far.

    Worse still, air pollution might do more than just weaken scent plumes（气味烟云）．Chemical reactions between air pollutants and plumes may transform the flowers' smells, creating new scents. And these scents may be unrecognizable to pollinators.

    That's certainly Fuentes' concern.  So, he says his next research project will look at how insects handle any new flower scent. "It's possible that some insects will change ways to detect and use these new molecules to find food," he says.

    A Song of Ice and Fire is a seven-part series of fantasy written for adults. George R. R. Martin writes each chapter from the perspective of a specific character, providing a limited point of view for each section. The reader is able to understand the inner workings of the individual, but the reader is barred from a whole understanding of the text. The world he has created has magic, but there is much more than that. While magic exists, it exists on the edge, and the inner unrest of the characters is much more important.

    His work also has a level of realness that is astonishing in a work of fantasy. Characters are imperfect, and many make questionable moral choices. In the end, however, Martin shows that both good and bad happen to both the people of high moral standard and the corrupt. He has made it clear that any character can die at any point, which has led to a lot of heartbreak from readers.

    In 2011, A Song of Ice and Fire became a television series titled Game of Thrones. Martin has been closely involved with the production. It has currently run for seven seasons, and viewers anxiously await the eighth season to answer their questions from the season seven finale.

    His fans are also waiting for The Winds of Winter and A Dream of Spring, the next books in the series, to answer the questions Martin and the television show have not yet addressed. Martin, however, has no plans to rush. He has made it clear that he will continue to write the books while working on the television show and writing other novels.

    But how will the story continue? What is going to happen in Westeros, and more importantly: when are we going to find out? Martinis skill as a writer has kept readers and viewers spellbound. Many hope he will finish the next book before the next season of the show begins, but no one knows with Martin. He always keeps his readers guessing.

    When she first started learning about the climate change from one of her elders, Fawn Sharp was invited on a helicopter flight over the Olympic Mountains to survey the Mount Anderson glacier(冰川). But the glacier was gone, melted by the warming climate. Sharp had a deep sense of loss when she discovered the glacier wasn't there anymore.

    Loss is a growing issue for people working and living on the front lines of climate change. And that gave Jennifer Wren Atkinson, a full-time lecturer at the University of Washington Bothell, US, an idea for a class.

    This term, she taught students on the Bothell campus about the emotional burdens of environmental study. She used the experiences of Nalive American tribes (部落) , scientists and activists, and asked her 24 students to face the reality that there is no easy fix -- that "this is such an intractable problem that they're going to be dealing with it for the rest of their lives.”

    Student Cody Dillon used to be a climate science skeptic (怀疑论者) . Then he did his own reading and research, and changed his mind.

    Dillon wasn't going into environmental work--he was a computer-science major. Yet, the potential for a worldwide environmental catastrophe seemed so real to him five years ago that he quit his job and became a full-time volunteer for an environmental group that worked on restoration (恢复) projects.

Six months into the work, he decided that Alkinson's class was just what he was looking for 一 a place where he could discuss his concerns about a changing climate.

Atkinson said she hopes the class helped her students prepare themselves for the amount of environmental loss that will happen over their lifetimes.

    “We are already changing the planet - . so many species are going to be lost, displaced or massively impacted (巨大影响的) ,”she said. “The future isn't going to be what they imagined.”

    With the explosion of consumer choices in recent history, the latest must-haves would surely need to be upgraded more often than every 10 years. In 2002 a computer and basic mobile phone would have been enough for most people, but now? The public need a trendy notebook computer and a smart phone with WiFi connection to feel they are up-to-date. So when will we have enough things? When will we finally be happy? Well, it looks like the things we buy today will barely keep us satisfied for a few months.

    In the eyes of some psychologists, far from making us happy, greater consumer choice creates many serious psychological problems. A fundamental principle of the society is that more freedom is better and more choice in the marketplace means more freedom. Therefore more choice leads to more happiness. This is not the case, however.

    Imagine you go to a café offering chocolate and vanilla ice cream. You choose the chocolate and eat it happily. But what if the café serves 50 kinds of ice cream? You choose chocolate and then start to worry, "maybe blueberry would have been better, perhaps the half-fat ice cream would have been healthier. Stupid me, all these choices and I didn't make the best one! "

    In China's major cities we have now passed the point where more consumer choice is making us happier. We are annoyed by all the options we have, disappointed because our expectations are so high and angered at ourselves when we don't make a perfect choice every time.

    A newspaper reporter tells a story about traveling on a plane with high-speed Internet access. He thought this was amazing—the newest piece of technology he had heard of. Then the service went down. The man next to him was angry and swore. The reporter thought, "How quickly the world owes him something he knew existed only 10 seconds ago!"

    Editor: Today our topic is part-time job. Are they good for school children or not?

    Headmaster: Certainly not. Children have got two full-time jobs already: growing up and going to school. Part-time jobs make them so tired that they fall asleep in class.

    Mrs. White: I agree. I know school hours are short, but there's homework as well, and children need a lot of sleep.

    Mr. White: Young children, perhaps some boys, stay at school until they're eighteen or nineteen. A part-time job can't harm them. In fact, it's good for them. They earn their pocket money instead of asking their parents for it. And they see something of the world outside school.

    Businessman: You're quite right. Boys learn a lot from a part-time job. And we mustn't forget that some families need the extra money. If the pupils didn't take part-time jobs, they couldn't stay at school.

    Editor: Well, we have got two for, and two against. What do our readers think?
