During a state of deep relaxation, several physiological changes take place in the body: the body's oxygen

consumption is reduced; the heart beat decreases; muscle tension and sweating ease, and there is decreased

sympathetic nervous system (交感神经系统) activity. This restful state not only allows the body to repair

and restore itself, but it has a calming effect on the consciousness.

How to achieve this state of relaxation, however, is a matter of opinion, and in some medical circles, a

matter of controversy. A recent report by Dr. David Holmes of the University of Kansas in the journal

"American psychologist" said that simply sitting in an armchair has just as many beneficial characteristics for

the body as meditation (冥想) does. Researchers of other relaxation techniques disagree. These experts believe

that more structured techniques, such as meditation, lead to a condition of deep relaxation.

The debate goes on, but one thing appears to be clear: the relaxation response can be reached by a number

of methods, and the methods themselves are not as important as getting there. One day, one method may work

best; on another day, an alternative method may be more appropriate. Once you are aware of all the methods,

you can find the one that works best on you.

Some of the relaxation techniques are meditation, auto analysis and progressive muscle relaxation response.

More than just sitting quietly in a chair, they have the added benefit of structure and discipline, and for these

reasons appear to be more effective for most individuals.

健康环保类阅读的知识点拨

健康环保类文章阅读技巧：

健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：

第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；

第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；

第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。

从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。
