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.

    What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result of where and how you live?{#blank#}1{#/blank#}

    We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle.{#blank#}2{#/blank#} Mental exercise is particularly important for young children. Many child psychologists think that parents should play with their children more often and give them problems to think about. {#blank#}3{#/blank#}38．__ If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent.

    {#blank#}4{#/blank#} According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive things to their children, such as “That was a very clever thing you did.” or “{#blank#}5{#/blank#}”.

A. A healthy body contributes to one's intelligence.

B. Parents should also be careful about what they say to young children.

C. What people want to express is like this.

D. The children are then more likely to grow up bright and intelligent.

E. It needs exercise.

F. You are such a smart child.

G. These are very old questions and the answers to them are still not clear.

How to Make Friends

    Friendship is a very important human relationship and everyone needs good friends. Good friendship has many benefits. It offers companionship, improves self-worth and promotes (促进) good health. There are times in our lives such as when we have recently moved into a new town, or changed our jobs or schools. Such changes often leave us without a friend. {#blank#}1{#/blank#} But for many of us the process is difficult and requires courage. Below are some helpful suggestions on how to make and keep friends.

● Associate with (与……交往) others.

    The first step to making friends is associating with other people. You can go to public places to meet new people. Besides, you will need to make yourself known by becoming an active member of such places.

● Start a conversation.

    Starting a conversation is the second most important step in making new friends. {#blank#}2{#/blank#} You can always start the conversation. Being able to make small talk is a very useful skill in relating with other people.

●{#blank#}3{#/blank#}

    Choosing friends with common interests is important in building friendship as these interests would always bring you and your friend together. Hanging out (闲逛) will always be a pleasant experience.

● Let it grow.

    It is a good thing to stay in touch. However, try not to press your new friend with calls, messages or visits as this would likely wear him or her out and finally you may lose your friend.{#blank#}4{#/blank#} The best friendships are the ones that grow naturally.

● Enjoy your friendship.

    The best way to enjoy your friendship is to allow your friends to be themselves. {#blank#}5{#/blank#} Try not to change them from who they are to what you want them to be. Become the kind of friend you will want your friend to be to you.

A. Do things together.

B. Be cheerful.

C. Making new friends comes easy for some people.

D. So you will need to give your friend time to respond to you.

    Why Don't Students Like School?

    Most of the teachers I know entered the job because they loved school as children.{#blank#}1{#/blank#} However, they are understandably discouraged when they find that some of their students don't like school much, and that they, the teachers, have great difficulty inspiring them. Why is it difficult to make school enjoyable for students?

    As a matter of fact , the brain is not designed for thinking. It's designed to ask you not to have to think, because the brain is actually not very good at thinking. Thinking is slow and unreliable.{#blank#}2{#/blank#}People like to solve problems, but they do not like to work on problems that cannot be solved. If schoolwork is always just a bit too difficult for a student, it should be no surprise that he doesn't like school much.{#blank#}3{#/blank#}

    What is the nature of being human?{#blank#}4{#/blank#} Many people would answer that it is our ability to reason that makes us different—birds can fly, fish can swim, and humans can think . (By thinking I mean solving problems, reasoning, reading something complex, or doing any mental work that requires some effort.)  Shakespeare thought highly of our cognitive(认知) ability in Hamlet: “What a piece of work is man! How noble in reason!” Some three hundred years later, however, Henry Ford came up with a quite different opinion, “Thinking is the hardest work there is, which is the probable reason why so few people are interested in it.” They both had a point of view. Humans are good at certain types of reasoning, especially compared to other animals, but we hardly often exercise those abilities.{#blank#}5{#/blank#}Thinking is not only painful, as Ford noted, it's also slow and unreliable.

A. A cognitive scientist would add another point of view, “Humans don't think very often because our brains are designed not for thought but for escaping from thought.”

B. What sets us apart from other species?

C. Of course you could make each decision with care and thought.

D. However, people enjoy thinking if it is successful.

E. Therefore, teachers should reconsider how they encourage their students to think, in order to make thinking enjoyable enough for students to go after.

F. If we are all so bad at thinking, how does anyone get through the day?

G. They want to help their students feel the same excitement and passion for learning that they felt.

    Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

    {#blank#}1{#/blank#} I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

    For those who do not particularly enjoy competitive sports —{#blank#}2{#/blank#}— there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

    Even after you have found a way for keeping in shape, through sport or gymnastics, {#blank#}3{#/blank#}, because, according to the experts, you must also master the art of complete mental and physical relaxation.{#blank#}4{#/blank#} Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity —{#blank#}5{#/blank#}— which were the natural way of life of our forefathers.

A. be active and practise Yoga

B. There are some aspects of our unhealthy lives that we cannot avoid.

C. it is especially difficult to do so if you are not good at them

D. physical effort on the one hand and relaxation on the other

E. they spent most of the time outdoors

F. you are still only half way to good health

G. It has to do with deep breathing, emptying your mind of all thoughts, meditation（冥想）, and so on.

    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.

B. Laughter helps you focus.

C. This finding has led to so-called clown doctors.

D. In fact, research done by scientists has shown that laughter has a lot of health benefits.

E. Laughter makes the world a better and more colorful place.

F. Some people may find the idea embarrassing at first.

G. Using laughter therapy in children's hospitals has proven to be invaluable.
