Psychologists deal with the mind and behavior. of people. Your mind consists of all your feelings, thoughts and ideas. It is the result of one part of the brain called the cerebrum. Your behavior. is the way you act or conduct yourself. Examples of behavior. include shouting, crying, laughing and sleeping.
Several people have been instrumental in the field of psychology. Whihelm Wundt set up the first psychological laboratory in Leipzig, Germany, in 1879. Ivan Pavlov, a Russian, is noted for his experiments with dogs in which he studies their reflexes(反射)and reactions. Around 1900, Sigmund Freud, stated his theory that people try to repress (control, hide) memories or thoughts that they believe were not good.
Psychologists should not be confused with psychiatrists who deal with mental illness. They are medical doctors who treat people.
This passage is mainly about ______.
A．studying the mind
B．memories and people
C．famous psychologists
D．the study of mental illness
During the hours when you labor through your work you may say that you're "hot." That's tree. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak. comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: "Get up, John! You'll be late for work again!" The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract (对抗) your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in day, rise before your usual hour. This won' t change your cycle, but you'll get up steam (鼓起干劲) and work better at your low point.
Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before petting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.
If a person finds getting up early a problem, most probably ______.
A．he is a lazy person
B．he refuses to follow his own energy cycle
C．he is not sure when his energy is low
D．he is at his peak in the afternoon or evening
There is no creature that does not need sleep or complete rest every day.
If you want to know why, just try going without sleep for a long period of time. You will discover that your mind and body would become too tired to work properly. You would become irritable and find it hard to think clearly or concentrate on your work. So sleep is quite simply the time when the cells of your body recover from the work of the day and build up supplies of energy for the next period of activity.
One of the things we all know about sleep is that we are unconscious in sleep. We do not know what is going on around us. But that doesn't mean the body stops all activity. The important organs continue to work during sleep, but most of the body functions are slowed down.
For example, our breathing becomes slower and deeper. The heart beats more slowly, and the blood pressure is lower. Our arms and legs become limp(柔软的) and muscles are at rest. It would be impossible for our body to relax to such an extent if we were awake. So sleep does for us what the most quiet rest can not do.
Your body temperature becomes lower when you are asleep, which is the reason people go to sleep under some kind of covers. And even though you are unconscious, many of your reflexes(习惯性思维) still work. For instance, if someone tickles(使觉得痒) your foot, you will put it away in your sleep, or even brush a fly from your forehead. You do these things without knowing it.
If you don't have as much sleep as your body needs, you will ______.
A．work properly
B．think clearly
C．keep your attention on your work
D．easily get angry
Are you superstitious？ No, of course not. Do you believe in magic (魔法), and luck charms (护身符), and elves or gremlins (小精灵) ？ Certainly not, but if I should greet you with the usual How's business？" You'll answer "Oh, just so-so" although your business is profiting greatly. When you are successful in some venture you might say you were just lucky. And yet, you know it was probably due to your a bility and hard work. Why？ Sometimes you knock on wood because wood was once a tree and there is a primitive belief that protective gods inhabit trees and knocking on wood attracts their attention so they may be credited with your successes.
If I should sneeze, only the strongest of you could refrain(克制而不) from saying "God bless you". Why bless this unsanitary (不讲究卫生的) habit？ Our ancestors believed that a sneeze opened the body to invasion by devils, and invoking (召唤) the name of God made the devils get out in a hurry. You may not realize it, but you express this same "devil invasion" when you say, "Whatever can have gotten into that child？" or "I wonder what possessed me to do that？"
Although they may no longer be believed, evidences of superstitions that have had their origins in the primitive fear of the unknown still exist in modern language and gestures.
The author ______.
A．believe that most people are superstitious
B．believe that very few people are superstitious
C．believes that there are still some evidences of superstitions in what we say and what we do
D．is superstitious

Of course, scientists can't answer all of your questions. If we ask, "Why is the ocean full of salty" scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into the cracks. The rain then carries the salt into he earth and into the rivers. The rivers carry the salt into the ocean. But then we ask, "What happens to the salt in the ocean？ The ocean doesn't get more slat every year". Scientists are not sure about the answer to this question.
We know a lot about our world. But there are still many answers that we do not have, and we are curious.
The main idea of this passage is ______.
A．people feel cool when they are near a lake or river
B．scientists can explain everything we want to know
C．scientists can explain many things but not everything
D．the salt in the ocean comes from rocks
