问题 单项选择题

In meditation (冥想), people sit quietly and focus their attention on their breath. As they breathe in and out, they attend to their feelings. As thoughts go through their minds, they let them go. Breathe. Let go. Breathe. Let go.
According to a recent study at the Insight Meditation Society in Barre, Massachusetts, three months of training in this kind of meditation causes a marked change in how the brain allocates (分配) attention. It appears that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly changing things and events in the outside world. Expert mediators are better than other people at catching such fast-changing stimuli(刺激), like facial-expressions.
The study provides evidence for changes in the workings of the brain with mental training. People can learn and improve abilities of all sorts with practice, everything from driving to playing the piano. The study has shown that meditation is good for the brain. It appears to reduce pressure and promote a sense of well-being.
In an experiment, 17 volunteers with no meditation experience in the experimental group spent three months meditating 10 to 12 hours a day. A control group also with no meditation experience meditated for 20 minutes a day over the same period. Both groups were then given the tests with two numbers in a group of letters. As both groups looked for the numbers, their brain activity was recorded.
Everyone could catch the first number. But the brain recordings showed that the less experienced mediators tended to grasp the first number and hang onto it, so they missed the second number. Those with more experience gave less attention to the first number, as if letting it go, which led to an increased ability to grasp the second number. This shows that attention can change with practice.
Just ask Daniel Levision, who meditated for three months as part of the study. "I am a much better listener," he said, "I do not get lost in my own personal reaction to what people are saying. \

问答题

阅读下列材料
材料1
中国工程院进行的一个咨询项目显示:在中国西北,生活在水环境严重污染地区和中度污染地区的人口数量,已占西北地区总人口的79.1%。严重污染的地区包括黄河干流、渭河干流、疏勒河流域以及伊犁河流域21个城市(地区)所在的主要河段,水质已不能满足农业灌溉用水的标准,有的已成为黑臭河段。 中度污染地区主要有新疆的乌鲁木齐市、甘肃的白银市以及陕西的铜川市等14个城市(地区),水质目前尚可满足工农业生产要求,但已不能作为饮用水源,而且基本已无环境容量,若不能控制排污很快将成为严重污染区。尚未明显污染的地区有27个地市,虽然这些水质良好区域的面积占西北地区总面积的59.8%,但大部分处于荒漠地带,其人口只占西北地区总人口的20.9%。
材料2
“必须清醒地看到,我国人口多、资源人均占有量少的国情不会改变,非再生性资源储量和可用量不断减少的趋势不会改变,资源环境对经济增长制约作用越来越大,人民群众对生态环境质量的要求也必然越来越高。从长远看,经济发展和人口资源环境的矛盾会越来越突出,可持续发展的压力会越来越大。对这些突出矛盾和问题,我们务必高度重视,按照树立和落实科学发展观的要求,始终把控制人口、节约资源、保护环境放在重要战略位置,把工作抓得紧而又紧、做得实而又实。”
——胡 * * 在中央人口资源环境工作座谈会上的讲话(2004年4月4日)
请回答:
(1)根据材料1说明什么是可持续发展
(2)根据材料2,结合环境的现状,说明保护环境和可持续发展的关系。
(3)谈谈如何坚持可持续发展战略
