Here, sleep experts clear up some of the biggest misunderstandings about sleep they see with their patients, which could weaken your ability to have a night of good sleep.

Myth: {#blank#}1{#/blank#}

    The latest research shows that the right amount of sleep may vary from person to person and should leave you feeling energized the next day. I'm a sleep doctor. Take myself for example. {#blank#}2{#/blank#}.

Myth: Don't fall asleep with the TV on.

    I've cured more people suffering from sleep problems than you can imagine by telling  people it's OK to fall asleep with the TV on. {#blank#}3{#/blank#}Control the watching time so it doesn't affect your sleep later in the night.

Myth: You can catch up on lost sleep on the weekend.

    {#blank#}4{#/blank#} A Harvard study found that even if you sleep for an extra 10 hours on the weekend to make up for only sleeping six hours a night for two weeks, those extra hours won't improve  your reaction times or ability to focus. Plus, sleeping late throws off your biological clock, which can lead to obesity, diabetes, and heart disease.

Myth: Alcohol can help you rest easy.

    {#blank#}5{#/blank#} Alcohol may relax you so you nod off quicker, but studies show you'll wake up more and get less of deep sleep you need to feel rested.

     “Let's Talk”：The Free Advice Project

A few weeks ago, I took a walk around Washington Square Park. I met all the usual people：street performers, the Pigeon Guy, a group of guitarists singing in harmony. But off to the side, sitting on a bench was a woman doing something vastly different—giving free advice.

    A week or two later, I set up an interview with her and we discussed her project at length.

    Lisa Podell, 32, started the Free Advice Project this past May. It began as an experiment；she sat in Washington Square Park for a day with a sign that read “Free Advice” as a simple way to reach out to people. Podell was astonished at the strong response.

    Podell admits that she was doubtful at first, but now she describes the project as mutually (相互地) beneficial. People learn from her—but she also learns from them. She says that the majority of those who come to her are dealing with some pretty heavy issues, and they expect her not only to listen, but also provide real answers.

    Having worked as a full time teacher and now as an adolescent advisor, Podell believes that talking things out is an important in the decision-making process.

    Sometimes, people walk around all day, keeping their problems in their own head and thinking about them in the same way. Podell simply strives to provide people with perspective.

    I asked if there is a future plan for the Free Advice Project. Podell said she would like to promote it to each public space in New York, which would be carried out by various volunteers across the city.

    It was truly inspiring to meet someone with such a big heart, especially in New York—where it is sometimes very hard to find anybody to listen.(303 words)

    Make a plan for attaining goals that you believe will make you happy. Your mood will very likely increase if you are going after something you value.

    Surround yourself with happy people. It is easy to begin to think negatively when you are surrounded by people who think that way. {#blank#}2{#/blank#}

    When something goes wrong, try to figure out a solution instead of being absorbed in self-pity. Truly happy people don't allow setbacks to affect their mood because they know that with a little thought they ran turn the circumstances back to their favor.

     {#blank#}3{#/blank#}These few minutes will give you the opportunity to focus on the positive things in your life and will lead you to continuous happiness.

     {#blank#}4{#/blank#}Whether you treat yourself to lunch, take a long, relaxing hath or simply spend a few extra minutes on your appearance, you will be subconsciously putting yourself in a better mood.

    Keeping healthy is another way to achieve happiness.  {#blank#}5{#/blank#}

    Why Is Recycling Important?

    When you throw things away, you might be very glad to do it. Unfortunately, that's not the end of the story. The things we throw away have to go somewhere－usually they go off to be buried underground in a landfill (垃圾填埋) or burnt in an incinerator (焚化炉). Landfills can be terribly polluting. They look awful, they smell terrible, they take up space that could be used for better things, and they sometimes create harmful soil and water pollution that can kill fish in our rivers and seas.

    One of the worst things about landfills is that they're wasting a huge amount of useful material. It takes a lot of energy and a lot of resources to make things, and when we throw those things in a landfill, at the end of their lives, we're also saying goodbye to all the energy and resources instead of burying it in landfills. That certainly has advantages: it reduces the amount of waste that has to be buried and we can get useful energy from it. But it can also produce harmful air pollution, and burning almost anything adds to the problem of global warming and climate change.

    The trouble is, we're all in the habit of throwing things away. In the early part of 20^th century, people used materials much more wisely－especially in World War Ⅱ, but in recent decades we've become a throwaway society. We tend to buy new things instead of getting old ones repaired. A lot of men use single-use razors (剃须刀), for example, instead of buying reusable ones, while a lot of women wear single-use stockings. Partly this is to do with the great convenience of throwaway items. It's also because they're cheap. But wasteful period in our history is coming to an end.

    We're finally starting to realize that our lifestyle is creating problems for future generations. Earth is soon going to be running on empty if we carry on as we are. Americans have a much richer life than almost anyone else on Earth. What happens when people in developing countries such as India and China decide they want to live the same way as us? According to the environmentalists, we'd need two Earths to satisfy all their needs.
