A noted American psychologist once remarked that childhood is a magical period in one’s life．Indeed it is, for during         one undergoes a step-by-step transformation not only in mental capacity, but also in physical and verbal skills．Each step          an increase in the difficulty of a child’s conceptual and learning abilities．During the early stages of childhood, from infancy to about five, the child learns          skills including using the toilet, bathing and dressing himself independently．At this stage, he also learns to be very observant, curious, imaginative and creative．His ability to remember things also        at this stage． He remembers details that an adult may have difficulty in remembering．Gradually , he learns elementary skills in problem-solving．At school, particular in         classes, the child is especially creative．Given a piece of paper and some colored pencils, he draws a variety of         from his surroundings as well as from his           circle．It is not surprising to see a child draw a monster to represent an abusive father, and an angel to represent a loving and caring mother．
As he graduates to the later stages of childhood bordering on the teenage years, the child learns the           of human relations and socialization by interacting with his peers—his friends and schoolmates． He also learns to          with new life situations, including dates and part-time work． Given a tight schedule of schoolwork, the child learns to prepare his own schedules of work and play; the more________ and less serious ones manage to take time out of their busy schedules of assignments, reports and tests and examinations to go with their friends on relaxation entertainment．

　Beware of those who use the truth to deceive(欺骗). When someone tells you something that is　　, but leaves out important information that should be　　, he can create a false impression.
For example, someone might say, “I just　　a hundred dollars on the lottery. It was great. I took that dollar ticket back to the store and　　it in for one hundred dollars!”
This guy is a winner, 　　? Maybe, maybe not. We then discover that he bought two hundred　　, and only one was a winner. He’s really a big　　!
He didn’t say anything that was　　, but he deliberately left out some important　　. That’s called a half-truth. Half-truths are not technically　　, but they are just as not　　.
Untrustworthy candidates in　　campaigns often use this tactic(手段). Let’s say that during Governor Smith’s last term, the state lost one million jobs and　　three million jobs. Then she　　another term. One of her opponents runs an ad　　, “During Governor Smith’s term, the state lost one million jobs!”That’s true. 　　, an honest statement would have been, “During Governor Smith’s term, the state had a net gain of　　million jobs. ”
Advertisers will sometimes use half-truths. It’s　　the law to make false claims so they try to mislead you with the　　. An ad might boast, “Nine out of ten doctors recommend Yucky Pills to cure nose pimples. ”It　　to mention that they only asked ten doctors and nine of them work for the Yucky Corporation.
This kind of deception happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.

If you do not use your arms or your legs for some time, they will become weak; and when you start using them again, they will slowly become strong again.        knows this, but nobody would think of      the fact.
Yet there are many people who         to know that the memory works in the same way. When someone says that        has a good memory, he        means that he keeps his memory in practice      exercising it very      , either consciously or unconsciously. When someone else says that his memory is      , he means that he does not give it enough       to become strong. The position is exactly the same as that of        people, one of       exercises his arms and legs by playing ball, while the other        in a chair or a car all day. If a friend of yours says that his arms are weak, we know that it is his own       , But if he tells us that he has a poor memory,       of us think that his parents are to blame, or that he is just      , and few of us realize that it is just as it was his arms or legs that were weak. Not all of us can become very strong in body or very clever in mind,        all of us can improve our strength and our memory by the same means that      .
Have you ever        that people who cannot read or write usually have       memories than those who can? Why is this? Of course, because they cannot write down something in a little notebook or something else. They have to remember names, places, songs and stories; so their memory is always being exercised.
In a word, if you want to have a good memory, do practice        things。

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were         to show that we all have “a body clock”          us, which controls the         and fall of our body energies,         us different from one day to the next.
The         of “a body clock” should not be too         since the lives of most living things are controlled         the 24 hour night-and-day cycle. We feel         and fall asleep at night and become         and energetic during the day. If the 24 hour-cycle is         , most people experience unpleasant         . For example, people who are not         to working at night can find that         of sleep causes them to         badly at work.
       the daily cycle of sleeping and        , we also have other cycles which        longer than one day. Most of us would         that we feel good on some days and not so good on         ; sometimes our ideas seem to flow and at other times, they         do not exist.

In Western countries, culture makes people think of themselves as highly ______ entities. When looking at scenes, Westerners tend to focus more on central objects than on their surroundings. East Asian cultures, however, ________ inter-dependence, When Easterners look at a scene, they tend to focus on the surroundings as well as the object.
Using an experiment ________ two tasks, Dr. Hedden asked subjects to look at a line simply to estimate its length, a task that played to American’s _______. In another, they estimated the line’s length relative to the size of a square, an easier task for the Asian.
The level of brain activity, by ______ blood flow, was then measured by Brain Scanners. The experiment found that although there was no difference in performance, and the tasks were very easy, the levels of activity in the subjects’ brain were ______. For the Americans, areas ______ to attention were more favorable to them, when they worked on the task they tended to find more difficult --- estimating the line’s size relative to the square. The findings are a ______ of more than ten years of previous experimental research into East-West differences.

For centuries, magicians have used various ways to shock the audience. We all have seen how a   36   performer carefully steps   37   a bed of burning coals -- barefoot. Then he walks across   38   a single burn on his feet. Is it mind over matter, or is it just physics? As it turns   __39  , walking on burning coals isn’t that hot as   40  . “The coals are hot enough to   41__  you, but if you walk quickly across them you   42   being burned.” says Jonathan Hall, a physician at Penn State University in Eric Pennsylvania.
That’s because some coals are made   43   burning wood chips. Wood has two   44__   properties（特性）for fire-walking, explains Hall. First, wood is an insulator（绝缘体）--it doesn’t   __45   heat very well. “It   46 _ time for heat to travel   47   the wood to your feet.” Hall says. If the performer walked across red-hot metal   48  , that would truly be   49  , because metal conducts, or transmits, heat very well. The metal would   50   burn a performer’s feet.
Second, wood has a low specific heat-- it doesn’t take much heat to   51   its temperature. Heat is a form of   52  . Temperature is a   53   of heat, in units of degrees. So   54   the coals are hot, the value（数值）of heat energy they contain is low. Thus, a well-trained performer can   55   such an amazing result.
Still, you don’t want to walk on burning coals, do you?
