Pleasure and Enjoyment

    When considering the kind of experience that makes life better, most people first think that happiness consists in experiencing pleasure: good food, all the comforts that money can buy. We imagine the satisfaction of traveling to exciting places or being surrounded by expensive devices. If we cannot afford those goals, then we are happy to settle for a quiet evening in front of the television set with a drink close by.

    Pleasure is a feeling of contentment that one achieves whenever expectations set by biological programs or by social conditioning have been met. The taste of food when we are hungry is pleasant because it reduces a physiological (生理的) imbalance. Resting in the evening while passively absorbing information from TV, with alcohol or drugs to dull the mind overexcited by the demands of work, is pleasantly relaxing. Traveling to Acapulco is pleasant because the exciting novelty (新奇) restores our sensations (感觉) exhausted by the repetitive routines of everyday life.

    When people think further about what makes their lives rewarding, they tend to move beyond pleasant memories and begin to remember other events, other experiences that overlap(重叠) with pleasurable ones but fall into a category that deserves a separate name: enjoyment. Enjoyable events occur when a person has not only met some expectation or satisfied a need or a desire but also gone beyond what he or she has been programmed to do and achieved something unexpected, perhaps something even unimagined before.

    Enjoyment is characterized by this forward movement: by a sense of novelty, of accomplishment. Playing a close game of tennis that stretches one's ability is enjoyable, as is reading a book that reveals things in a new light, as is having a conversation that leads us to express ideas we didn't know we had. Closing a contested business deal, or any piece of work well done, is enjoyable. None of these experiences may be particularly pleasurable at the time they are taking place, but afterward we think back on them and say, “That really was fun” and wish they would happen again. After an enjoyable event we know that we have changed, that our self has grown: in some respect, we have become more complex as a result of it.

    Experiences that give pleasure can also give enjoyment, but the two sensations are quite different. For instance, everybody takes pleasure in eating. To enjoy food, however, is more difficult. A gourmet (美食家) enjoys eating, as does anyone who pays enough attention to a meal so as to discriminate the various sensations provided by it. As this example suggests, we can experience pleasure without any investment of psychic energy, whereas enjoyment happens only as a result of unusual investments of attention. A person can feel pleasure without any effort, but it is impossible to enjoy a tennis game, a book, or a conversation unless attention is fully concentrated on the activity.

Test-taking tips

    Do you sweat, check your pencil, and feel butterflies in your stomach as your teacher hands out the test paper? A lot of people feel anxious when it is time to take a test. Here are some tips for taking tests:

    {#blank#}1{#/blank#}. Your memory recall will be much better if you have had enough rest. In a scientific study, people who got enough sleep before taking a math test did better than those who stayed up all night studying.

    Read the test through first. Once you have the test paper in front of you, read over the entire test, checking out how long it is and all the parts that you are expected to complete.{#blank#}2{#/blank#}.If something seems unclear before you start, do not worry: ask the teacher.

    Focus on addressing each question individually. {#blank#}3{#/blank#}. Instead, answer the best way you can or skip over the question and come back to it after you have answered other questions.

    Relax. {#blank#}4{#/blank#}. Of course you cannot get up and move around in the middle of a test, but you can wiggle your fingers and toes, take four or five deep breaths. As we all know, it can be easy to forget things we know well. During a test, if you forget something and start to get nervous, it suddenly becomes much more difficult to remember.

    Finished already? Although most teachers will let you hand your test paper in early, it is usually a good idea to spend any extra time checking over your work. {#blank#}5{#/blank#}. On the other hand, if you have 5 minutes until the bell rings and you are still writing, end up whatever you are working on without panic.

A. This will allow you to decide how much time you have for each section

B. Be sure you have studied properly

C. Get enough sleep the night before the test

D. As the teacher hands out the test paper, be sure you know what is expected of you

E. As you take the test, if you do not know an answer, do not worry about it

F. You can also add details that you may not have thought you'd have time for

G. If you are so nervous that you blank out, you might need a mini-break

    Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.{#blank#}1{#/blank#}

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.

    Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day.{#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right.{#blank#}4{#/blank#} The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

    If Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

    Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. {#blank#}5{#/blank#} "You keep what matters," Tononi says.

A. We should also try to sleep well the night before.

B. It's as if the brain is preserving its most important memories.

C. That's why students do better in tests if they get a chance to sleep after learning.

D. Similarly, when people go for a few days without sleeping, they get sick.

E. The processes take place to stop our brains becoming loaded with memories.

F. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.

G. "Sleep is the price we pay for learning," says Giulio Tononi, who developed the idea.

Spacewalk!

    Most people don't know that the anniversary of an important event in space exploration occurred last month. On March 18, 1965, spaceman Aleksi Leonov became the first human to complete an Extra Vehicular Activity (EVA) or spacewalk. It marked the first time that a human was able to leave a spacecraft and operate in the emptiness of space. It is a dangerous procedure, but one that is vital for the success of manned space missions.

    {#blank#}1{#/blank#} In space, a spacesuit must protect people from extreme cold and heat, provide air to breathe, and remove extra carbon dioxide. {#blank#}2{#/blank#} Too much of it, and the spacesuit becomes firm and difficult to move in. Too little of it, and astronauts can become dangerously sick after returning to their spacecraft.

    Astronauts now perform complex jobs in the emptiness of space in modern spacesuits. They have logged many hours repairing and upgrading equipment on satellites during EVAs. {#blank#}3{#/blank#} On July 20^th, 1969, American astronaut Neil Armstrong set foot on the moon for the first time. There is no atmosphere on the moon, but there is gravity—about 17 percent of Earth's, which means Neil needed a special suit for walking on the moon's surface. Suits for the moon are equipped for exploration far from any vehicles, including tough boots that can resist cuts from the rough surface while walking. But sharp rocks weren't the only danger to astronauts.

    The moon surface is covered with a fine and flour-like dust which consists of small particles (颗粒) left over from the numerous meteorite (陨石) strikes on the moon. {#blank#}4{#/blank#} When astronauts would leave the moon's gravity, the dust on their suits began floating all over. It got into delicate equipment inside the spacecraft and the astronaut's eyes and lungs. As different space agencies plan for returning people to the moon, new EVA suit designs will have to take something else into account. Keeping astronauts safe also means keeping their suits clean.

A. However, EVAs don't just happen in empty space.

B. It sticks to everything, eventually causing joints and seals to fail.

C. Spacesuits also have to maintain ideal air pressure during a spacewalk.

D. Unfortunately, most people have no idea about space exploration or spacesuits.

E. Without the ability to work in space, we are unable to keep our space programs functional.

F. There are a few things that must be taken into account to make an EVA both safe and effective
