如何使用大腦 How to Use Our Brain
Human brain is the most complex and intelligent mechanism inthe world. It is the major factor that distinguishes man from animals. With our brain we get to know the world and make agood use of the world to our benefit.
Our brain is aproduct of constant use through millions of years. Other things can be used up, but used properly, our brain can never beexhausted. In fact, the more we use it, the more capable and efficient it will become. Excessive use of the brain, however,will causea lot of problems. So it is useful to know how to use our brain wisely.
First, handwork or physical labor is good exercise as wellas rest for our brain. Doing handwork and brain work alternatively can help develop both our brain and hands. Secondly, weshould avoid doing brainwork for long hours on end. The brain, though 3% of the body weight, when at work, consumes 20% ofthe oxygen carried by 16% of the blood in circulation. A long period of brainwork may cause, through lack of bodily activity,slow blood circulation and inadequate oxygen supply to the brain, resulting in inefficiency and possible damage to the brain.
如何使用我們的大腦（用腦之道）1。人腦的重要性及作用。2。如何科學用腦。[寫作導航]先寫大腦的特性和作用（複雜，智能的器官，使人區別於動物等）;再寫大腦越用越靈，但過度使用也會出問題，爲第三段作鋪墊;第三段從兩方面說明如何合理用腦：一是勞逸結合，手腦交替;二是從科學的角度，利用數據，說明過度用腦可能給大腦帶來的傷害。[範文]人腦是世界上最複雜和最聰明的機制。這是主要因素區別於動物的人。隨着我們的大腦，我們去認識世界，作出了有利於世界對我們很好地利用。我們的大腦是通過數百萬年經常使用的產品。其他的東西可以使用，但是使用得當，我們的大腦不能被耗盡。事實上，我們越使用它，就越能有效將成爲。過度使用大腦，但是，將causea很多問題。因此，有必要了解如何明智地使用我們的大腦。首先，手工或體力勞動是很好的運動，以及對我們的大腦休息。做手工和腦力勞動交替發展既可以幫助我們的大腦和雙手。第二，我們應該避免這樣做就結束長時間腦力勞動。大腦，雖然3％的體重，在工作時，消耗的20氧氣16％，流通進行血液％。阿長期的腦力工作可能造成的通過身體缺乏活動，血液循環緩慢，氧氣供應不足，大腦，造成效率低下和可能損害大腦。
