    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.

    After entering high school, you must wonder how to study well. Here are some good skills for you.

Go to class.

    If you want to do well at school, going to class is the first step in studying well. If you miss classes, you will miss what the teacher thinks is important; as a result, you'll miss what is the most likely to end up on the test.{#blank#}1{#/blank#}

Take good notes.

    Try not to write down everything.{#blank#}2{#/blank#}Write down unfamiliar terms. After class, review your notes as soon as possible. You can fill in details that you missed and review the material while it is still fresh on your mind.

{#blank#}3{#/blank#}

    If you are struggling in class, talk to your teacher. He or she may be able to give you more help or tutor you before or after class. Most teachers have little sympathy(同情) for students who just become worried about failing during the last few weeks of the grading period.

Take part in class discussions.

    In order to learn more in class, it is helpful to take part i n class discussions. Asking questions and having eye contact with your teachers and classmates can increase your participation(参与) and your focus during the class discussion.{#blank#}4{#/blank#} This helps you make your point clear in class.

Form study groups.

    {#blank#}5{#/blank#}Make sure that everyone is familiar with the material because you do not want to spend time re-teaching material to people who do not understand it. Be careful! Sometimes group sessions can become chatting sessions.

A. Don't be late for your class.

B. Talk to your teacher if you need help.

C. You should write down all the new terms.

D. So if you want to study well, go to every class.

E. Get students together who want to do well in class.

F. All you need is to put the main points in your own words.

G. If the material is difficult, you'd better read it before class.

    Everybody gets stressed time to time. {#blank#}1{#/blank#} Some ways of dealing with stress like screaming or hitting someone don't solve much. But other ways, like talking to someone you trust, can lead you to solving your problem or at least feeling better.

    Try taking these four steps the next time you are stressed:

    ⑴Get support. When you need help, reach out to the people who care about you. Talk to a trusted adult, such as a parent or other relatives. {#blank#}2{#/blank#} They might have had similar problems, such as dealing with a test, or the death of a beloved pet.

    ⑵Don't take it out on yourself. Sometimes when kids are stressed and upset they take it out on themselves. Oh, dear, that's good idea. Remember that there are always people to help you. Don't take it out on yourself. {#blank#}3{#/blank#}

    ⑶Try to solve the problem. After you're calm and you have support from adults and friends, it's time to get down to business. {#blank#}4{#/blank#} Even if you can't solve it all, you can solve a piece of it.

    ⑷Be positive. Most stress won't last long. Remember stress does go away, especially when you figure out the problem and start working on solving it.

    These steps aren't magic, but they do work. And if you can stay positive as you make your way through a hard time, you'll help yourself feel better even faster. {#blank#}5{#/blank#}

A. Ask for a helping hand to get you through the difficult situation.

B. Notice your friends' feelings and find a way to help them.

C. Different people feel stress in different ways.

D. Ah, it feels so good when the stress is gone.

E. You need to figure out what the problem is.

F. And don't forget about your friends.

G. Then, find a way to calm down.

    Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month. {#blank#}1{#/blank#}

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.

    Support is growing for a theory that sleep evolved so that connections between neurons(神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day. {#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right. {#blank#}4{#/blank#}The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

    If Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

    Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. {#blank#}5{#/blank#} "You keep what matters," Tononi says.

A. We should also try to sleep well the night before.

B. It's as if the brain is preserving its most important memories.

C. Similarly, when people go for a few days without sleeping, they get sick.

D. The processes take place to stop our brains becoming loaded with memories.

E. That's why students do better in tests if they get a chance to sleep after learning.

F. "Sleep is the price we pay for learning," says Giulio Tononi, who developed the idea.

G. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.

How to Avoid an Internet Addiction

It may seem like everyone surfs the web these days. But if you can't have interest in other aspects of your life because of the Internet, you may be on your way to an Internet addiction. You might fear you're the only one who has experienced that feeling. {#blank#}1{#/blank#} Luckily, there are some ways to avoid living your life in front of the computer. 

{#blank#}2{#/blank#}.

More and more people in the world are becoming addicted to the Internet, and you are not the only one with this problem. So do not be embarrassed. Just be brave to admit that you are on your way to an Internet addiction. And then find others with the same problem and help each other beat it. 

Set aside limited time for computer use. 

Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed when you are not using it. {#blank#}3{#/blank#} If you have a desktop PC, try not to go near it or put something over it like a sheet. 

Call people instead of sending instant messages or texts. 

If you are free on weekends, call friends and ask them to go outside to do something you enjoy, like playing a sport. This will take your mind off the computer. {#blank#}4{#/blank#}.

Use an alarm clock or timer（计时器）. 

Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get away from the computer when the time is up. Alternatively create a shutdown timer on your desktop. {#blank#}5{#/blank#}.

A. The truth, though, is that it's quite common to be an addict. 

B. When the computer is not looking at you, you are less likely to use it.

C. Being addicted to it is quite normal. 

D. Admit you are at risk of an addiction. 

E. If you have a problem on weekdays, phone your friends or ask for help in person. 

F. This will stop you from using the Internet so often or going on to another page. 

G. This can be programmed to shut down your computer after the set time.
