What is your favourite colour? Do you like yellow, orange, red?. Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be pessimist(悲观者). At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings..If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.
. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day..A black bridge over the Thames River, near London, used to be the scene of more suicides(自杀) than any other bridge in the area---until it was repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
.It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.

It makes no difference what you read or study if you can't remember it. You just waste your valuable time．One dependable aid that does help you remember what you study is to have a specific purpose or reason for reading．
Why does a clerk in a store go away when your reply to her offer to help is, “No, thank you．I'm just looking.”? Both you and she know that if you aren't sure what you want, you are not likely to find it．But suppose you say instead, “Yes, thank you．I want a pair of sun glasses.” She says, “Right this way, please”
If you choose a book, “just looking” for nothing in particular, you are likely to get just that--nothing．But if you do know what you want, you are almost sure to get it．Your reasons will vary; they will include reading or studying “to find out more about”, “to understand the reasons for” and “to find out how”．
Before you start to study, you say to yourself something like this, “I want to know why Stephen Vincent Benet happened to write about America”．Because you know why you are reading or studying, you relate the information to your purpose and remember it better．
At least two important processes go on at the same time．As you read, you take in ideas rapidly and accurately. But at the same time you express your own ideas to
yourself as you react to what you read. You have a kind of mental conversation with the author．
This additional process of thinking about what you read includes evaluating it, relating it to what you already know, and using it for your own purposes．One part of critical reading, as you have discovered, is distinguishing between facts and opinions．Facts can be checked by evidence, opinions are one’s own personalreactions．Another part of critical reading is judging sources．Still another part is drawing accurate inferences．

A．Maybe you have already discovered some clever ways to keep yourself from forgetting．

B．It is important for students to have a positive attitude to their study．

C．You remember better when you know what you' re reading．

D．In other words, a good reader is a critical reader．

E. It’s quite the same with your studying．
F. Reading is not one single activity．
G. This is the way it works．

The Meanings of Dreams
Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but they still know very little about why we dream.
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 cannot remember doing so when we awaken. While we are asleep, it works more slowly and sometimes puts our thoughts and memories together in strange ways.
Some believe that our dreams are associated with thoughts and feelings that we experience while we are awake. Many dream researchers think that a dream about death, for example, is really about an important life change. Dreams about a car or travel often represent feelings about your own life. Dreams about teeth – especially broken or loose ones may indicate stress and 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 (叫喊), for example, maybe you are angry.
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 terrified, then maybe you are afraid of something.

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

E. There are three things you should pay attention to to have a sweet dream.
F. Finally, a part of our brain helps us to understand daily experiences we have.
G. Dreams about telephones are thought to be about giving or receiving an important message.

Expressions about water are almost as common as water.
The expression “to be in hot water” is one of them. It is a very old expression. “Hot water” was used five hundred years ago to mean being in trouble. One story says it got that meaning from the custom of extremely throwing hot water down on enemies attacking a castle. When we are in “hot water”, we are in trouble. A young boy can be in hot water with his mother if he comes into the house with dirty shoes.
A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job.
Another common expression, “to hold water”, is about the strength or weakness of an idea or opinion that you may be arguing about. If it can hold water, it is strong and has no holes in it. If your argument can hold water, it is strong and does not have any holes.
“Throwing cold water” also is an expression that deals with ideas or proposals.For example, you want to buy a new car because the old one has some problems. But your wife “throws cold water” on the idea, because she says a new car costs too much.

A．It means disliking an idea.

B．You are in a difficult situation.

C．A person who breaks a law can be in hot water with the police.

D．If it does not hold water, then it is weak and not worth debating.

E. But many of the expressions using water have unpleasant meanings.
F. A man who has long been jobless will find it hard to make both ends meet.
G. “To keep your head above water” is a colorful expression that means staying out of debt.

Smiles and tears are part of life. But do you find enough time for laughing? I’m not asking if you experience lots of good times.

Erma talks with many children who have cancer and learns important lessons from them. She learns, for example, that cancer survivors（幸存者）know how they should smile at life, though they are receivingchemotherapy（化疗）.
.Jessica’s leg was cut off at the knee because of cancer. She was learning to wear a prosthesis（假肢）. Jessica told about playing soccer. She hit the ball hard with her foot. The ball flew off in one direction while her man-made leg flew another way. Then the brave girl lay on the floor, laughing happily.
As the saying goes, “” Do you find plenty of time to laugh?
