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.

    You fall down on the road and a kid you barely know rushes over to help. You come home after a long day to find your dad has prepared your favorite meal. Just before lunch in social studies class, you learn about places where people don't have clean water or enough food.{#blank#}1{#/blank#}They're likely to make you feel grateful.

    Gratitude (感恩) is one of many positive emotions. It's about focusing on what's good in our lives and being thankful for the things we have.{#blank#}2{#/blank#} It's taking a moment to reflect on how fortunate we are when something good happens — whether it's a small thing or a big thing.

    {#blank#}3{#/blank#}Making a habit of gratitude can also be good for us. Like other positive emotions, feeling grateful on a regular basis can have a big effect on our lives. Brain research shows that positive emotions are good for our bodies, minds, and brains.

    Positive emotions open us up to see more possibilities and take in more information. They improve our ability to develop skills, learn, and make good decisions.{#blank#}4{#/blank#} When we feel grateful for someone's kindness toward us, we may be more likely to do a kindness in return. Thanking people can make it more likely they'll do a kindness again.

    Traveling to all corners of the world gets easier and easier. We live in a global village, but this doesn't mean that we all behave in the same way.

    {#blank#}1{#/blank#}An American shakes your hand firmly while looking you straight in the eye. In many part of Asia, there is no physical contact at all, in Japan, you should bow, and the more respect you want to show, the deeper you should bow. In Thailand, people greet each other by pressing both hands together at the chest.{#blank#}2{#/blank#}

    Many countries rules about what you should wear and what you shouldn't wear. In Muslim countries, you shouldn't reveal(暴露) the body, especially women, who should wear long blouses and skirts.{#blank#}3{#/blank#}Remember to place them neatly together where you came in.

    In Spain, lunch is often the biggest meal of the day, and can last two or three hours. For this reason many people eat a light breakfast and a late dinner. In Mexico, lunch is the time to relax, and many people prefer not to discuss business as they eat.{#blank#}4{#/blank#}

    It is not as simple as opening the door and hitting the track in winter. There are a few things you can do to ensure you are getting the most out of your run, and, importantly, not doing more harm than good.

    Warm up, cool down

    {#blank#}1{#/blank#} Your muscles need some time to warm up when it's cold  so take it easy when you set off and do a few stretches (伸展) once you're finished.

    Drink water

    You might not feel hot, but that's because sweat evaporates (蒸发) more quickly into the chilly, dry air. So be sure to drink water before, during and after cold-weather workouts. {#blank#}2{#/blank#} A belt bottle conveniently attaches to your waist so you don't have to carry it and can have a drink whenever you feel like it.

    {#blank#}3{#/blank#}

    Running in cotton is a bad idea. Wear thin, breathable layers of synthetic (合成的) clothing that help protect you from the wind and snow, but still let out heat and moisture (水分).Thirty percent of your body heat escapes through your hands and forty percent through your head. Wear a hat, or beanie (无边小便帽), and gloves so your circulatory system can distribute warm blood to the rest of your body. {#blank#}4{#/blank#}

    Run into the wind

    {#blank#}5{#/blank#} Obviously, it will be an easier passage home with some extra help from Mother Nature. But, more importantly, you won't have the wind in your face for the second half of your run, when you are more likely to be sweating and catch a chill.

Nobel, who was born in Stockholm, is a great scientist famous for his dangerous experiments.

    Nobel studied in the US and then Russia between 1850 and 1859. {#blank#}1{#/blank#} As is known, bomb is dangerous to life, but Nobel was working under that condition. Once a big explosion in his lab completely destroyed the lab and caused some deaths. {#blank#}2{#/blank#} He received criticism and satire, but he proceeded with the work rather than losing heart. From 1860s to 1880s, Nobel made many achievements and his inventions were first used in building roads and digging tunnels. Most of the bombs were safer and more possible to be controlled. Even at the end of the 20th century, we still used his methods.

    {#blank#}3{#/blank#} He was quick to see industrial3openings for his scientific inventions and built up over 80 companies in 20 different countries. Indeed his greatness lay in his outstanding ability to combine the qualities of an original scientist with those of a forward-looking industrialist.

    {#blank#}4{#/blank#} Seldom happy, he was always4searching for a meaning to life, and from his youth, he had taken a serious interest in literature and philosophy. His greatest wish, however, was to see an end to wars, and thus peace between nations, and he spent much time and money working for this cause. To follow his will, a fund was set up to encourage people to make great progress in physics, chemistry, physiology, medicine, literature and peace. {#blank#}5{#/blank#}

A. After his return, he started researching into bombs.

B. After that he had to experiment on a boat in a lake.

C. Everyone knows the story of his famous invention.

D. That's the Nobel Prize which means great honour to a scientist.

E. Nobel had many patents in Britain and other European countries.

F. Most of his theories have been tested and found to be true though some may sound strange.

G. But Nobel's main concern was never with making money or even with making scientific
