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.

    Homework is a major part of going to school: It's your teachers' way of evaluating(评价)how much you understand of what's going on in class. {#blank#}1{#/blank#}Luckily, you can do a few things to make homework less work.

    Be sure you understand the homework.

    Write your homework down in your notebook or day planner if you need to. {#blank#}2{#/blank#}It's much easier to take a minute to ask the teacher during or after class than to struggle to remember later that night!

    Use any extra time in school.

    Many schools have study halls that are specifically designed to allow students to study. It's tempting(诱惑)to hang out with friends during study periods or unstructured(松散的) time. {#blank#}3{#/blank#}

    Take a break.

    {#blank#}4{#/blank#}So take some breaks while doing your homework. Sitting for too long without stretching or relaxing will make you less productive than if you stop every so often. Taking a 15minute break every hour is a good idea for most people.

    {#blank#}5{#/blank#}

    If you don't finish your homework during school, think about how much you have left and what else is going on that day, and then budget your time. Most highschool students have between 1 and 3 hours of homework a night. If it's a heavy homework day and it seems like you've got an assignment in every subject but gym and lunch, you'll need to devote more time to homework. It's a good idea to come up with some kind of homework schedule（日程）, especially if you are involved in sports or activities or have an afterschool job.

A.Pace yourself.

B.Settle down to do homework.

C.And it helps digest important concepts(概念).

D.Most people's attention spans(注意力持续时间)aren't very long.

E.Don't be afraid to ask questions about what's expected.

F.Once your homework is done, you can check over it if you have extra time.

G.But the more work you can get done in school, the less you'll have to do that night.

    Many people believe that there is some truth in the saying Laughter is the best medicine.{#blank#}1{#/blank#} Laughter helps relieve pain, strengthen the immune system and reduce stress. Laughter stimulates(激发) hormones which make us feel happy. Laughter also increases the flow of blood throughout the body and has benefits which are similar to the ones you get by doing exercise.

    {#blank#}2{#/blank#}Children exposed to funny films and cartoons before major medical procedures are able to cope better with pain and anxiety.{#blank#}3{#/blank#} These are professional clowns who are sent to hospitals and wards to entertain and distract sick children.

    Laughter therapy has become very popular in recent years and as a result, more and more laughter clubs are starting to open up in cities and towns all over the world. At a laughter session, a trained therapist instructs the group to perform a series of exercises which are designed to produce laughter. {#blank#}4{#/blank#}And it takes them some time to get rid of their inhibitions(心理抑制).They might even start off with fake laughter, but this doesn't matter because our bodies can't tell the difference, and the results are the same. Moreover, laughter is contagious(传染的).{#blank#}5{#/blank#}

    So next time you feel ill, stressed out or depressed, try watching a funny film or try remembering an amusing incident in your life. You will soon feel better.

A. If one person starts giggling, it is unavoidable that everyone else will be drawn in.

    Thanksgiving Day is special holiday in the United States and Canada. {#blank#}1{#/blank#}

    Thanksgiving Day is really a harvest festival. This is why it is celebrated in late fall, after the crops are in. {#blank#}2{#/blank#} On December 4, 1619, the Pilgrims from England landed near what is now Charles City, Virginia. They knelt down and thanked God for their safe journey across the Atlantic.

    {#blank#}3{#/blank#} The Pilgrims landed at what is now Plymouth, Massachusetts, in 1620. They had a difficult time and the first winter was cruel. Many of the Pilgrims died. But the next year, they had a good harvest. So Governor Bradford declared a three-day feast (盛宴). {#blank#}4{#/blank#} Everyone brought food.

    In time, other colonies (殖民地) began to celebrate a day of thanksgiving. But it took years before there was a national Thanksgiving Day. During the Civil War, Sarah Josepha Hale persuaded Abraham Lincoln to do something about it. {#blank#}5{#/blank#} Today, Americans celebrate this happy harvest festival on the fourth Thursday in November. Canadians celebrate Thanksgiving Day in much the same way as their American neighbours. But the Canadian thanks-giving Day falls on the second Monday in October.

A. But one of the first thanksgivings in America had nothing to do with a good harvest.

B. He declared the last Thursday of November 1863 as a day of thanksgiving.

C. The Pilgrims were those who celebrated the first Thanksgiving Day.

D. Families and friends gather to eat and give thanks for their blessing.

E. The Pilgrims invited Indian friends to join them for their special feast.

F. This is why he decided to make it a national holiday throughout the U.S.

    Zoey admits it was a little sad saying goodbye to her fish. {#blank#}1{#/blank#} Zoey's class at Hawthorne Elementary School spent most of the school year raising the fish from time they were nothing more than little eggs with eyes.

    The program the Hawthorne kids took part in is called" Trout in the classroom". {#blank#}2{#/blank#} The kids at Wilson Middle School in Fishersville took part in the project, too.

    "I got to feed them every morning and watch them grow up," said seventh-grader Lauren Clayton. We have to protect them, or some of the fish could go extinct." Lauren was right. {#blank#}3{#/blank#} But later, pollution, overfishing and loss of natural habitat have pushed some species to the danger of extinction.

    Thanks to the kids in the program, trout are being reintroduced into rivers and streams across the country. And by doing that, the kids are helping to restore there local ecosystems—the natural balance that existed before human disturbed it,

    {#blank#}4{#/blank#} Because the fish are in their classrooms, the kids are responsible for making sure there is cool, clean water, proper food and proper living conditions in the tanks.

    By the middle of May, they were "as big as a finger." That is, they are old enough to be released into Oneida Creek." Remember to swim back here to meet us and eat the food we bring little trout". {#blank#}5{#/blank#}
