Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but they still know very little about why we dream.

    {#blank#}1{#/blank#} First, we have most of our dreams during REM (rapid eye movement) sleep. At this time, the brain is very active. Second, everyone dreams, even if we can't remember doing so when we awake. {#blank#}2{#/blank#} While we are asleep, it works more slowly and sometimes puts our thoughts and memories together in strange ways.

{#blank#}3{#/blank#} Some believe that our dreams are relevant to thoughts and feelings that we experience while we are awake. Many dreams researchers think that a dream about death, for example, is really about an important life change. {#blank#}4{#/blank#} A dream about teeth—especially broken or loose ones-may suggest stress or fear. Dreams in which you are flying often represent freedom or escape.

   Researchers think people in our dreams can tell us something about ourselves. If the person in the dream was yelling, for example, maybe you are angry. {#blank#}5{#/blank#}

There is still a lot about dreaming that we do not understand. By learning more about our dreams, we may learn more about ourselves.

    A. Dreams may be more important than sleep.

    B. Scientists do not know for certain why we dream.

    C. If he or she was scared then maybe you are terrified of something.

    D. Modern research can tell us some important things about dreams.

    E. There are three things you should pay attention to have a sweet dream.

    F. Finally, a part of our brain helps us to understand daily experience we have.

    G. Dreams about telephones are thought to be about giving or receiving messages.

    {#blank#}1{#/blank#} When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, visions of country clubs dance into view.

    The many wants of mankind might be regarded as making up several levels. {#blank#}2{#/blank#}.

    The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. {#blank#}3{#/blank#} It included such items as cars and new houses.

    By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels mean physical satisfaction－the feeding, comfort, safety, and transportation of the human body－this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called “luxury” items(奢侈品). Among them are vacation trips, the best medical care, and entertainment. {#blank#}4{#/blank#}

    On this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?

    A fifth level probably would be wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. {#blank#}5{#/blank#} In this way, we can enjoy more fully the good things on the first four levels.

 A．Then a third level appeared.

 B．Human wants seem endless.

 C．When there is money enough to satisfy one level of wants, another level appears.

 D．There are several levels of wants in one's life.

 E．At this stage, we now may seek to ensure the health, safety, and leisure.

 F．Also included here are fancy foods and the latest styles in clothing.

 G．Different people have different wants on each level

How to Simplify Your Life

    Less is more. This is why we say: reduce things by half instead of doubling them, get rid of junk instead of piling it up, relax instead of stressing, slow down instead of speeding up. Apply these principles in your everyday life in a conscious way. You will then find yourself well along on your journey to simplification.

    When you concentrate on one task, you find you have energy that you didn't even know you had. Just imagine: you are at a fair and you have to carry two heavy pigs over 100 yards. If you keep grabbing one and then the other, it will take forever, because one of them will keep slipping out from under your arm and running off. But if you tie one pig in a place, pick up the other, gather all your strength and make a dash for the finish line, pause for a moment, run back and get the other one, and with great determination, carry the second pig to the finish line, then you can be sure of success.

    The pressure at work is on the increase in all occupations. In the modern nuclear family, the expectations that formerly would have been shared among all the relatives are now concentrated on the individual partner.

If you have the feeling that 24 hours per day are not enough for all the things you need to do, then it's not because the day has too few hours, but because you have too many activities. A simple fact that overloaded people often tend to forget. The solution is equally simple: refuse to accept so many work assignments in your private life or your working life.

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

     “I can handle stress” is regarded as a positive statement in the world of work. People who can handle stress are given more and more to cope with—until one day they break.

    Pay careful attention to the signs that tell you that you are under more stress than you can cope with. These signals can come from various areas of life. You become ill, or your work efficiency decreases.

If you have any of these symptoms, change your life goals and decrease your tolerance of stress. Say quite openly, “I can't manage that.”

{#blank#}4{#/blank#}

     “If only I were slimmer, more beautiful, richer, more clever, then I would be happier.” This is a dream that makes a lot of people ill, depressed, and unhappy. Life has its flaws, defects, corners, and edges. Only those who accept this reality can lead a really full life.

Of course there are activities in which errors are dangerous：driving a car, crossing the road. But life doesn't consist entirely of these things. In among them there is a lot of room for small and large mistakes.

{#blank#}5{#/blank#}

    Successful people all have their own places where they can withdraw in order to work. Find out which places improve your creativity. For me it's the train. When I know that I'm going to be traveling for four hours without phone calls and people knocking on my door, I find my mind is free and I can read or write complex articles. There can be problems working on the train, of course: if the person sitting opposite you keeps talking away, or if train trips make you tired(some people fall asleep after a few miles)．

    To be more grateful (感恩的) in life means that you are also allowing yourself to be happier and more satisfied with everything that has been going on around you. But with all the stress, all the disappointments and all the anxiety around you. I bet you ask yourself this question all the time: “How exactly can I be more grateful with my life?”{#blank#}1{#/blank#}.

    ⒈ Learn to live in the moment.

    Life is a wonderful adventure full of enriching experiences and endless possibilities. Don't just go through the motions of (走过场) repetitive(重复乏味的) activities and boring tasks. No! Being a mindless zombie (行尸走肉) can make you more likely to take things for granted (对……不予重视).{#blank#}2{#/blank#}, make an effort to enjoy the experience.

    You're supposed to attend a conference? Absorb it. Babysit your niece? Enjoy the moment. Eat a 15-minute lunch? Taste each bite.

    ⒉{#blank#}3{#/blank#}

    Being aware of your goal to be more grateful can help you look for things to be really more grateful for. Gratitude is a conscious decision. You have to practice it consistently (持续的，始终如一地).

    ⒊ Control your thoughts.

    Of course you have the power to control what you're thinking of! Consider this exercise, for example: if you find yourself thinking more and more self-entitled (自我为中心), stop.{#blank#}4{#/blank#}. You are given consciousness (意识). Make use of it wisely.

    ⒋Always resist the temptation (诱惑) of comparing yourself with other people.

    As humans, we have the natural tendency (倾向、偏好）to compare ourselves with others with the hope of attaining satisfaction. Actually, this kind of activity does not help you feel to be more grateful in life.{#blank#}5{#/blank#}! You will always be meeting someone richer, which makes you fed inferior (下等的) to others!

    Don't do it, please.

    Every little thing counts. You have the ability to make yourself feel to be more grateful in your life.

A. Appreciate what you had in the past

B. And if you find yourself repeating negative (消极的) junk, stop

C. It does the opposite

D. Express gratitude all the time

E. Well, the following are some tips to help you with this particular concern (忧虑)

F. Instead of doing something just for the sake of (为了) doing it

G. Words that stress you and make you feel worthless should definitely be removed

    How long could you stand on Antarctic ice before your bare feet froze solid? A minute. Maybe two? If you're an emperor penguin, you can do it for two months in cruel winds at as low as-75 degrees Fahrenheit{#blank#}1{#/blank#}, but their special circulation acts as a kind of antifreeze to keep them warm enough.

    Penguin legs and feet have evolved to lose as little heat as possible. Penguin feet preserve heat by restricting blood flow in really cold weather, keeping foot temperature just above freezing{#blank#}2{#/blank#}.

    Blood vessels to and from the feet are very narrow and woven closely together, cooling the blood from the body on the way to the feet and heating the blood as it returns to the body.{#blank#}3{#/blank#}.

    This special ability is part of how penguins keep their eggs warm until they hatch. Each penguin egg's father balances it on his feet and covers it with his very warm layer of feathered skin to keep it cozy while females are out feeding at sea.{#blank#}4{#/blank#}. If females haven't returned with food by time the chicks hatch, male penguins feed their babies for a few days on a kind of "milk" made from special cells inside their throats.

    {#blank#}5{#/blank#}Your hands get whiter during freezing weather because there's less blood in them which has been redirected to the central part of your body to make sure vital organs stay warm.

A. Penguin legs work like a heat exchange system

B. Those naked bird feet may look extremely cold

C. Therefore, the male penguins must stay together in groups

D. However, parenting doesn't stop there for these devoted fathers

E. Emperor penguins also have the ability to 'recycle' their own body heat

F. Feet get cool blood so there's less heat to lose, while the body stays warm and comfortable

G. In fact. humans have the ability to restrict blood flow to their hands and feet in cold weather too
