关于科学的英语手抄报
一、手抄报的介绍： 手抄报是指将选定的资料手抄在纸张（一般是卡纸）上所完成的作品。 通常手抄报是中学生开展课外活动的形式之一。学生直接参与编辑、撰写、制作等的全过程，深受学生的喜爱。每当重大的节日我们都会以各种各样的形式来表达，或祝愿或庆祝或歌功，比如迎元旦、迎“五四”、庆“七一”、庆国庆等。 三、手抄报的编绘制作的步骤 编绘制作是落实由设想到具体着手完成的重要步骤。 其步骤有二：一是准备阶段，另一是编制阶段。 1、准备阶段。 主要是各种材料、工具的准备。具体包括：拟定本期手抄报的报名；准备好一张白棒纸（大小视需要而定，有半开，四开，八开等，学校手抄报比赛是要求为《遵义晚报》大小，即半开）；编辑、撰写有关的文字材料（文章宜多准备些）；书写、绘图工具等。 2、编制阶段。 这个阶段是手抄报制作的主要过程。大致为：版面设计、抄写过程、美化过程。 （1）版面设计：根据文章的长短进行排版，并画好格子或格线（一般用铅笔轻轻描出，手抄报制作完毕后可擦可不擦）。 （2）抄写过程：指的是文章的书写。手抄报的用纸多半是白色，故文字的书写宜用碳素墨水；字体宜用行书和楷书，少用草书和篆书；字的个头大小要适中（符合通常的阅读习惯）。字写得不是很漂亮不要怕，关键在于书写一定要工整。另外，文章或标题中不能出现错别字。 （3）美化过程：文章抄写完毕后，即可进行插图、尾花、花边的绘制（不宜先插图后抄写），将整个版面美化。这个过程是手抄报版面出效果的关键过程。 手抄报可以是黑白的，也可是彩色的。可以是综合性的，也可以专题性的。手抄报的制作设计与黑板报制作设计要求和步骤大体是相同的。 手抄报的形式 办手抄报用八开纸的版面，中间对折成为一、二两版。要求有标题，有刊头刊尾。版面布局合理，排版教学设计与设计匀称。字迹规范美观，一律用签字笔或钢笔书写。 手抄报的内容 手抄报的内容丰富多样，既可以是知识积累为主，也可以涉及学科探讨，难题寻解；既可以复习旧知识，也可以预习新内容。具体要求：一般配合教学内容及进度来拟定小报的内容，每二周一期，每期要求有明确的标题，确定重点内容。主次分明，版面新颖活泼。 手抄报的版面设计同报刊、杂志、黑板报的版式设计基本相同。它是在一块固定的平面上进行。一张好的校园手抄报，不仅内容充实、版式美观，而且会给读者以生动活泼、富有新意的艺术感染力。因此，建议在编排手抄报时应注意以下几点： 一、构思 当我们要编排一张手抄报的时候，首先要根据这张报所刊登的内容与精神来选择必要的文章，而文章的多少则要根据版面的大小而定。一般校园手抄报常用八开纸为宜，可安排文章6—8篇。 二、版面编排 一般适合于成人阅读的报纸、杂志都是以文字为主的版面进行编排，而校园手抄报则不同，除文章内容以文字形式表现外，还应在版面设计上进行插图、标出主题、点缀、上色美化等装饰，达到图文并茂。这样，使版面显得生动活泼，适合中小学生。 三、编排程序 1、 根据文章的多少与每篇的内容字数，划分出大致的版面安排。 2、 根据选定的字形大小、字距、行距的宽窄，确定格子的长宽大小、字距、行距，然后用铅笔轻轻地打上格子。 3、 起稿。先把每篇文章的题目确定出合适的位置，然后进行抄文。 4、 点缀。用铅笔或钢笔在文章的头尾处进行勾划、配图。 5、 上色。用彩色笔对题目、插图等进行上色。 6、 校对与修整。手抄报办完后一是要对编排的文章进行检查，发现错字漏词进行修改。二是对上色后的效果进行调整，以达到均匀美观、完整统一。这样，一幅完整的手抄报作品就完成了。 四、版面设计是出好手抄报的重要环节。 1、版面设计：要设计好版面，须注意以下几点： （1）明确本期手抄报的主要内容是什么，选用有一定意义的报头（即报名）。一般报头应设计在最醒目的位置； （2）通读所编辑或撰写的文章并计算其字数，根据文章内容及篇幅的长短进行编辑（即排版）。一般重要文章放在显要位置（即头版）； （3）要注意长短文章穿插和横排竖排相结合，使版面既工整又生动活泼； （4）排版还须注意：字的排列以横为主以竖为辅，行距要大于字距，篇与篇之间要有空隙，篇与边之间要有空隙，且与纸的四周要有3cm左右的空边。另外，报面始终要保持干净、整洁。 你的手抄报是以论语为内容的，听起来很复杂，其实没有想象的那么难，在你策划好的地方，画个圣人孔子图像，然后在你觉得该写子的地方写上一篇论语～ 不过要注意一点的就是，手抄报和其他报一样～～ 要办好它，不要把图文分开，这样显的很单调的，图文想结合，效果肯定很好的 很多手抄报的样子，可以做参详。而且办手抄报并不难。下面是怎样办手抄报的步骤： 怎样进行手抄报的设计与制作，大体上可以从这三个方面来阐述： 一、美化与设计的步骤； 二、报头、插图与尾花的表现； 三、编辑抄写描绘制作过程。 一、美化与设计 手抄报的美化与设计涉及的范围主要有：版面设计与报头、题花、插图、尾花和花边设计等。 2、报头 报头起着开门见山的作用，必须紧密配合主题内容，形象生动地反映手抄报的主要思想。报名要取得有积极、健康、富有意义的名字。 报头一般由主题图形，报头文字和几何形体色块或花边而定，或严肃或活泼、或方形或圆形、或素雅或重彩。 报头设计应注意： （1）构图要稳定，画面结构要紧凑，报头在设计与表现手法上力求简炼，要反映手抄报的主题，起“一目了然”之效； （2）其字要大，字体或行或楷，或彩色或黑白； （3）其位置有几种设计方案：一是排版设计为两个版面的，应放在右上部；二是排版设计为整版的，则可或正中或左上或右上。一般均设计在版面的上部，不宜放在其下端。 3、题头 题头（即题花）一般在文章前端或与文章题图结合在一起。设计题头要注意以题目文字为主，字略大。装饰图形须根据文章内容及版面的需要而定。文章标题字要书写得小于报题的文字，要大于正文的文字。总之，要注意主次分明。 4、插图与尾花 插图是根据内容及版面装饰的需要进行设计，好的插图既可以美化版面又可以帮助读者理解文章内容。插图及尾花占的位置不宜太大，易显得空且乱。尾花大都是出于版面美化的需要而设计的，多以花草或几何形图案为主。插图和尾花并不是所有的文章都需要的，并非多多益善，应得“画龙点睛”之效。 5、花边 花边是手抄报中不可少的。有的报头、题头设计可用花边；重要文章用花边作外框；文章之间也可用花边分隔；有的整个版面上下或左右也可用花边隔开。在花边的运用中常用的多是直线或波状线等。 二、报头画、插图与尾花的表现手法 报头画、插图与尾花的表现手法大致可分为线描画法和色块画法两种。 1、线描画法 要求形象简炼、概括，用线准确，主次分明。作画时要注意一定的步骤： （1）一般扼要画出主线----确定角度、方向和大小； （2）再画出与图相关的比例、结构及透视； （3）刻画细部，结合形体结构、构图、色调画出线条的节奏变化； （4）最后进行整理，使画面完整统一。 2、色块画法 除要求造型准确外，还须善于处理色块的搭配和变化关系，而这些关系的处理要从对象的需要出发，使版面色彩丰富。作画时，可先画铅笔稿（力求造型准确），再均匀平涂大色块；后刻画细部；最后进行修整，使之更加统一完美。 线描画法与色块画法，通常是同时使用，可以是多色亦可单色。不管是线描还是色块画法，最好不要只用铅笔去画。版面上的图形或文字不能剪贴。 四、注意的问题 1、 漫无边际，没有天地。在编排过程中，必须画出一定的边缘部分，既有天地，又胡左右。天大地小会出现重心下移，天小地大又会感觉头重脚轻，左右不均，除给读者不舒服感觉外，还不利于装订保存。一般四缘部分为2—3厘米为宜。 2、 主次不分。在规划版面时要注意分清主次。重点文章、主要标题，一定要安排在上方头版显著位置上。 3、 版面不活。文章的大小、字块的分割、横竖（横排或竖排）的穿插要交错进行，不要一个模式，这样显得活泼。 4、 喧宾夺主。校园手抄报其最大特点是图文并茂，喜闻乐见，但要做到以文为主，以图为辅，防止满报是图，宾主不分。 5、 版面拥挤。一般说来，文章与题目、文章与文章必须间隔一定的距离，使之左右均衡、大小疏密，字体统一（标题可作变化），视觉上有不轻不重的感觉。 6、 长文不分栏。一般文章从左至右，通排一行不宜过长，过长则看起来困难，且版面呆板。适合人们习惯的报刊阅读距离不超过8厘米，否则，应分栏抄写。 7、 标题不显。标题是内容的中心句，应用不同的字体或大小、或上色、或点缀、划线进行突出，使读者一目了然。 8、 彩笔过多。手抄报文字书写一般用蓝黑钢笔进行抄写，除了标题可用彩笔外，正文一般不要用彩笔。在喜庆节日或重大活动的专刊上，可适当增加一些色彩艳丽的字块，以渲染气氛。 五、色彩的运用 色彩对人的情感调节作用，已被无数的研究所证明。这是从色彩的情感共鸣和象征意义的两个功能来说，因为色彩最容易给人们留下记忆，它可以引发人们意识中的某种情感，使人们在潜意识中对五光十色的自然界产生一种心理折射。目前市场上常见的多种彩笔很适合中小学生应用，它具有笔触细腻、饱和、圆润、色彩鲜艳等特点，但其色彩的运用要考虑到读者。各种色彩的特点和象征意义如下： 色相 情绪感觉 象征意义 红 喜庆、热情、吉祥 革命、庄严、警觉 黄 明亮、愉快、娇嫩 希望、高贵、轻薄 蓝 宁静、清凉、伤感 和平、博大、冷淡 白 素雅、肃穆、凉爽 纯洁、崇高、清高 黑 厚重、恐惧、神秘 严肃、悲哀、内向 绿 健康、向上、滋润 安全、青春、生机 紫 妩媚、优雅、孤独 贵重、神奇、魔幻 橙 炽烈、欢乐、奔放 温暖、神化、躁动 灰 含蓄、俭朴、沉着 沉默、高雅、空虚 褐 稳健、古朴、曲雅 大方、枯寂、苍老 金 神圣、威严、华贵 富有、尊敬、珍重 银 清雅、高贵、稳健 脱俗、圣洁、自傲 2005级理科班2008-2009学年度第二学期第一期班刊 2005级理科班2008-2009学年度第二学期第一期校刊 学校治安服务队2008-2009学年度第二学期第一期校刊 2005级信息(2)班2008-2009学年度第二学期第一期校刊 2007级数学教育(1)班2008-2009学年度第二学期第一期校刊

可以这样写：
However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources become scarce.
Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.

为什么大脑忙起来人就容易饿
A busy brain can mean a hungry body.
大脑忙碌可能会导致身体饥饿。
We often seek food after focused mental activity, like preparing for an exam or poring overspreadsheets.
我们经常在集中进行脑力活动后寻找食物，比如备考或阅读报表。
Researchers speculate that heavy bouts of thinking drain energy from the brain, whosecapacity to store fuel is very limited.
研究者猜测，高强度思考会耗尽脑部能量，而脑部存储养分的能力十分有限。
So the brain, sensing that it may soon require more calories to keep going, apparentlystimulates bodily hunger, and even though there has been little in the way of physicalmovement or caloric expenditure, we eat.
所以，大脑感觉自己可能很快就需要更多热量来维持运转，显然会因此刺激身体产生饥饿感。尽管几乎没有进行体力运动或出现热量消耗，我们还是会吃东西。
This process may partly account for the weight gain so commonly seen in college students.
这个过程可以部分解释大学生中常见的体重增加现象。
Scientists at the University of Alabama at Birmingham and another institution recentlyexperimented with exercise to counter such post--study food binges.
前不久，亚拉巴马大学伯明翰分校(University of Alabama at Birmingham)的科学家们和另一个研究机构试验通过运动对抗学习后的暴饮暴食。
Gary Hunter, an exercise physiologist at U.A.B., oversaw the study, which was published thismonth in the journal Medicine Science in Sports Exercise.
这项研究由亚拉巴马大学伯明翰分校的运动生理学家加里•亨特(Gary Hunter)主持，本月发表在《体育医学与科学》(Medicine Science in Sports Exercise)上。
Hunter notes that strenuous activity both increases the amount of blood sugar and lactate — abyproduct of intense muscle contractions — circulating in the blood and augments blood flowto the head.
亨特指出，剧烈活动会增加在血液中循环的血糖和乳酸盐含量——这是肌肉剧烈收缩的副作用——增加脑部的血流量。
Because the brain uses sugar and lactate as fuel, researchers wondered if the increased flow offuel-rich blood during exercise could feed an exhausted brain and reduce the urge to overeat.
大脑以糖和乳酸盐为养料，所以研究者们想知道，锻炼中增加的养料丰富的血流量是否能给疲惫的大脑提供养分，从而减轻过度进食的冲动。
Thirty--eight healthy college students were invited to U.A.B.’s exercise lab to determine theirfitness and metabolic rates — and to report what their favorite pizza was.
38名健康的大学生被邀请到亚拉巴马大学伯明翰分校的运动实验室，接受健康水平和代谢率检测，并报告自己最喜欢吃哪种披萨。
Afterward, they sat quietly for 35 minutes before being given as much of their favorite pizza asthey wanted, which established a baseline measure of self--indulgence.
之后，他们静坐35分钟，然后他们想吃多少披萨就供应多少，以确定自我放纵的基线。
At a later date, the volunteers returned and spent 20 minutes tackling selections from collegeand graduate--school entrance exams.
在后来的一个日子里，志愿者们返回这里，花费20分钟时间做从大学和研究生入学考试中挑选的题目。
Hunter says this work has been used in other studies to induce mental fatigue and hunger.
亨特说，这种方法已经在其他研究中被用于引发精神疲劳和饥饿感。
Next, half the students sat quietly for 15 minutes, before being given pizza.
接下来，其中一半学生静坐15分钟，然后进食披萨。
The rest of the volunteers spent those 15 minutes doing intervals on a treadmill: two minutesof hard running followed by about one minute of walking, repeated five times.
剩下的志愿者用那15分钟时间在跑步机上做运动：快跑2分钟，然后走大约1分钟，重复5次。
This is the sort of brief but intensive routine, Hunter says, that should prompt the release ofsugar and lactate into the bloodstream.
亨特说，这种短暂而高强度的运动应该能促进糖和乳酸盐释放到血流中。
These students were then allowed to gorge on pizza, too.
这些学生之后也被允许尽情食用披萨。
But by and large, they did not overeat.
总体来说，他们没有过量进食。
In fact, the researchers calculated that the exercisers consumed about 25 fewer calories thanthey did during their baseline session.
实际上，研究者们计算出，这些锻炼者摄入的热量比在基线测试阶段大约少25卡路里。
The nonexercisers, however, consumed about 100 calories more.
但是，那些没有锻炼的人大约多摄入了100卡路里。
When the researchers factored in the calories expended on running, they determined thatthose students actually consumed 200 fewer total calories after their brain workouts than theresting students.
研究者们把跑步中耗费的热量计算在内后发现，那些学生实际上在脑力活动后比其他学生一共少摄入200卡路里。
The study has limitations, of course.
这项研究当然具有局限性。
We only looked at lunch, Hunter says; the researchers do not know if the runners consumedextra calories at dinner.
我们只研究了午餐，亨特说。研究者不知道跑步者在晚餐时是否摄入了更多热量。
They also cannot tell whether other types of exercise would have the same effect as running,although Hunter says they suspect that if an activity causes someone to break into a sweat, itshould also increase blood sugar and lactate, feeding the brain and weakening hunger’s call.
他们也不知道其他哪些运动会收到和跑步一样的效果，不过亨特说，他们猜测，如果一项运动能让人出汗，那么它应该也能增加血糖和乳酸盐释放，给大脑提供养分，从而缓解饥饿感。
科学英文手抄报
Science drink milk little common sense 5
Drinking milk is good for health, but many people drink milk in still exist a number of the error on the idea, this paper introduces some scientific drinking milk little common sense.
The 1 morning fasting drink milk should not be. Because the human body when fasting gastrointestinal peristalsis quickly, nutrition in milk are often too late to be absorbed quickly into the e.. In addition, big milk method is insufficient, because this will reduce in oral and salivary mixed opportunity, is not conducive to digestion and absorption. Drink milk before the best to eat some cookies, cakes, or eat snacks while drinking milk.
2 night milk more favorable. Scientific studies found that, in the human body calcium metabolism will have a special rule: the evening especially midnight when the content of serum calcium, there will be a" trough", forcing the body through regulating mechanism of transport a portion of bone calcium supplement. In this way, calcium in the blood is temporarily maintained, but have reduced skeletal calcium in. Milk of calcium rich, therefore before bedtime drink a cup of milk, can compensate for human body needs calcium at night.
3 milk should not be adding sugar boiling. Milk is rich in amino acids, in the condition of high temperature in the milk of lysine with sugars occurring Maillard reaction, generate a new compounds - fructosyl amino acid. This substance can not only for human digestion and absorption, but affect human health, the best milk fresh drinking, such as cold a little heating can.
4 do not like milk can drink yoghurt. The milk has a" repulsive " most people with lactose intolerance, these people can try drinking yoghurt. In the yogurt lactose content significantly reduced, but almost all retain the milk nutrition, wherein the lactic acid bacteria in the human body can survive and reproduction, conducive to nutrient absorption and utilization and improve immunity. Yogurt not containing antibiotics, easy to digest the absorption to fasting drinking.
5 can not be heated drinking yoghurt. Drink sour milk feeds mainly on its nutrition and live bacteria, such as yogurt heating, the body can only drink nutrition to lose biological activity of lactic acid bacteria, so don't heating after drinking.

Crane, stork, heron, long-legged bird always stand on one leg and sleep, tired to change the other foot rest, is a model.
Partridge rest like swarms around in a circle, and then as head outwards inward end. In this way, regardless of the enemy from which direction the hit, they can find and run away.
Thrush, Braun and other sounds melodious birds, sleep usually bent legs, claws bent up firmly grasp branches, so don't worry they will fell down from the tree.

Fish have gills, can breathe water, fishes have a swim bladder, can be in the water freely ups and downs. However, some people say the fish that lives in the water will drown, is this true?
Although it sounds ridiculous, but it is true. Fish is fish swimming" buoy", which can be inflated and deflated to adjust the proportion of fish body. In this way, the fish in the swimming requires only minimal muscle activity, will be in the light of floating stability. However, when the fish sink to a certain depth ( i.e." depth" ), the outside huge pressure will cause it to wither section bladder volume. At this time, it 's buoyancy less than its own gravity, so he can't help to submerged to, also do not float, and was ultimately unable to breathe and drowned. Although, the fish also can swing through fins and tail upwards, but if the sink too deep, do also be of no avail.
On the other hand, living in the deep sea fish, because their bones can bear great pressure, so they can live a free life in deep water. If we live in the deep sea fish fast to get the" depth" of above, because it is the inner pressure of the body not with the outside world smaller pressure equilibrium is reached, it will constantly" expansion" to float to the surface. Sometimes, it even took out," burst".

A dull boy
Greedy will decrease cerebral blood flow
If an excessive eating or stop a moment to eat, the body volume of blood, including brain blood mobilization to the gastrointestinal tract. While adequate blood supply is the development premise, if often in ischemic state, its development must be affected.
Greedy will cause obesity brain""
Over-eating, especially the intake of nourishing food, food into energy will greatly exceed the consumption quantity of heat, the heat energy into fat accumulation in the body. If the brain too much fat, obesity can cause brain"". Research confirms, human intelligence and cerebral sulci folds much about, cerebral sulcus and more obvious, more folds, the higher the level of intelligence. While obesity brain make groove back tightly abutted together, folds disappeared, the cerebral cortex was smooth, and the neural network development difference, so, intellectual level can be reduced.
Greedy will inhibit brain intelligent regional physiological function
The human brain activity patterns of excitation and inhibition is mutually induced in certain parts of the brain, is excited, its adjacent to the site of some areas in the inhibited state, excited more strengthen, peripheral site inhibition is more deepen, and vice versa. Therefore, if the head of the gastrointestinal tract to digest plant nerve center for gluttonous excess food and long time excited, it is bound to cause adjacent language, thinking, memory, imagination and intelligence of brain regional inhibition. These areas such as often is in the state of suppression, intelligence will be worse.
Greedy for constipation and brain damage
Children's snack mostly with high nutrition fine food, eat easy constipation. Constipation, metabolite accumulation in the digestive tract for a long time, the role of intestinal bacteria produce a large quantity of harmful substances, easily treated by intestinal absorption, into the blood circulation, stimulate the brain, the brain nerve cells of chronic poisoning, affecting the normal development of the brain.
Greedy will induce brain failure
Scientists found in a study, one can induce brain senescence substances -- fibroblast growth factor, due to increased satiety of food after tens of thousands of times, this is a kind of arteriosclerosis substance, so from long-term sense, greedy will cause premature aging of the brain.
科学饮乳小常识5则
喝牛奶有益健康，但不少人在喝奶方面还存在一些观念上的误区，现介绍一些科学饮乳的小常识。
1.晨起空腹喝奶不宜。因为人体空腹时胃肠蠕动快，牛奶中营养物质往往来不及被吸收就匆匆进入大肠。此外，大口喝奶的方法也不足取，因为这样会减少在口腔中和唾液混合的机会，不利于消化吸收。喝牛奶前最好先吃些饼干、糕点等，或边吃点心边喝牛奶。
2.晚上喝奶更有利。科学研究发现，人体中的钙代谢会有一个特殊的规律：晚间尤其是午夜之际，血浆钙含量会出现一个"低谷"，迫使机体通过调节机制调运一部分骨骼中的钙来补充。这样，血液中的钙虽暂时得到维持，但骨骼中钙却有减少。牛奶中含钙丰富，因此临睡前喝杯牛奶，可补偿人体夜间对钙的需求。
3.牛奶不宜加糖煮沸。牛奶中含有丰富的氨基酸，在高温条件下牛奶中的赖氨酸与糖发生梅拉德反应，生成一种新化合物--果糖基氨基酸。这种物质非但不能为人体消化吸收，反而影响人体健康，牛奶最好新鲜饮用，如太冷稍稍加热即可。
4.不喜牛奶可饮酸奶。对牛奶有"反感"的人大多患乳糖不耐症，这些人可尝试饮用酸奶。酸奶中的乳糖含量大大降低，但几乎保留了牛奶所有的营养，其中的乳酸菌在人体内能存活繁殖，有利于营养物质的吸收利用并提高免疫力。酸奶中不含抗菌素，易消化吸收所以能空腹饮用。
5.酸奶不能加热饮用。喝酸奶主要吃它的营养和活菌，如酸奶加热，人体只能喝到营养却失去了有生物活性的乳酸菌，因此不要加热后饮用。
鸟怎样睡觉的
白天，鸟儿们在枝头穿梭呜叫，在蓝天下自由飞翔，到了晚上，它们和我们人一样也要休息、睡觉，恢复体力，不过它们睡觉的姿势可是各不相同哦!
美丽的绿头鸭和天鹅们，白天在水中捕食、戏耍，夜晚休息时也离不开它们最爱的水面。它们把优美的长脖子弯曲着，将头埋在翅膀里，然后让自己漂浮在水面上，一边做着美梦，一边随波逐流，好不悠闲。
鹤、鹳、鹭等长腿鸟总是单脚独立而睡，累了再换另一只脚，是劳逸结合的典范。
鹧鸪休息时喜欢成群围成一个大圈，然后一律头朝外尾向内。这样，不管敌人从哪个方向袭来，它们都能及时发现并逃走。
画眉、百灵等叫声悦耳的小鸟，睡觉时通常弯下两腿，爪子则弯曲起来牢牢地抓住枝条，所以不用担心它们会从树上摔下来。
而猫头鹰这种“值夜班”的猛禽，你总能在白天看见它睁一只眼，闭一只眼，站立在浓密的树枝上，其实这时它正在睡觉呢。猫头鹰的睡觉姿势是不是很另类啊，它这样可是为了时刻监视周围环境防备着敌人的袭击哦!
=================================
鱼也会溺死吗
鱼有鳃，可以在水中呼吸，鱼有鳔，可以在水中自由地沉浮。可是，有人说生活在水中的鱼也会溺死，这是真的吗?
虽然这听起来很荒谬，但却是事实。鱼鳔是鱼游泳时的“救生圈”，它可以通过充气和放气来调节鱼体的比重。这样，鱼在游动时只需要最小的肌肉活动，便能在水中保持不沉不浮的稳定状态。不过，当鱼下沉到一定水深(即“临界深度”)后，外界巨大的压力会使它无法再凋节鳔的体积。这时，它受到的浮力小于自身的重力，于是就不由自主地向水底沉去，再也浮不起来了，并最终因无法呼吸而溺死。虽然，鱼还可以通过摆动鳍和尾往上浮，可是如果沉得太深的话，这样做也无济于事。
另一方面，生活在深海的鱼类，由于它们的骨骼能承受很大的压力，所以它们可以在深水中自由地生活。如果我们把生活在深海中的鱼快速弄到“临界深度”以上，由于它身体内部的压力无法与外界较小的压力达到平衡，因此它就会不断地“膨胀”直至浮到水面上。有时，它甚至会把内脏吐出来，“炸裂”而死。

贪吃孩子变笨
贪吃会降低大脑的血流量
若一次进食过量或一刻不停地进食，会把人体里的大量血液，包括大脑的血液调集到胃肠道来。而充足的血供应是发育前提，如果经常处于缺血状态，其发育必然会受到影响。
贪吃会造成“肥胖脑”
吃得过饱，尤其是进食过量高营养食品，食入的热量就会大大超过消耗的热量，使热能转变成脂肪在体内蓄积。若脑组织的脂肪过多，就会引起“肥胖脑”。研究证实，人的智力与大脑沟回皱褶多少有关，大脑的沟回越明显，皱褶越多，智力水平越高。而肥胖脑使沟回紧紧靠在一起，皱褶消失，大脑皮层呈平滑样，而且神经网络的发育也差，所以，智力水平就会降低。
贪吃会抑制大脑智能区域的生理功能
人的大脑活动方式是兴奋和抑制相互诱导的，即大脑某些部位兴奋了，其相邻部位的一些区域就处于抑制状态，兴奋越加强，周围部位的抑制就越加深，反之亦然。因此，若主管胃肠道消化的植物神经中枢因贪吃过量食物而长时间兴奋，这就必然引起邻近的语言、思维、记忆、想象等大脑智能区域的抑制。这些区域如经常处于抑制状态，智力会越来越差。
贪吃会因便秘而伤害大脑
孩子的零食大多以高营养的精细食品为主，吃了容易发生便秘。便秘时，代谢产物久积于消化道，经肠道细菌作用后产生大量有害物质，容易经肠吸收，进入血液循环，刺激大脑，使脑神经细胞慢性中毒，影响脑的正常发育。
贪吃还会促使大脑早衰
科学家在一项研究中发现，一种能促使大脑早衰的物质——纤维芽细胞生长因子，会因过饱食物而于饭后增加数万倍，这是一种能促使动脉硬化的物质，因而从长远意义上讲，贪吃会使大脑过早衰老。
