Construction technology requirements are as follows: template template Panel selection and processing require plate high strength, good toughness and P76 活动 1.答:根据P75图3.16数据，了解到地球的淡水只占全球水的2.5%，说明淡水资源少;而目前人类利用的淡水资源仅占全球淡水资源的0.3%，说明人们现在能利用的淡水资源更少。 原因:近几十年来，随着全球人口增长，经济发展，以及人们生活水平的提高，对水资源的需求与日俱增，不少国家和地区出现了水资源不足的问题;同时，人类对水资源的污染和浪费，进一步加剧了水资源危机。 活动 2.答:有全球性水危机、我国的水危机。主要谈谈水资源危机的原因(与上题同);让学生平时通过阅读报刊、电视新闻等手段，收集包括土地日、水日、气象日等每年的活动主题。 对策:兴建水库，跨流域调水，节约用水，保护水资源。 -------------------------------------------------------------------------------------------------------------------- P80 活动 1.答:我国水资源的时空分布不匀，与我国的季风气候及河流分布密切相关。从全国范围看，季风区内水资源多，非季风区水资源少。 而季风区内:(1)从时间分配看，时间分布不均，因为降水夏秋多，冬春少。(夏季，风从海上吹来，降水集中，汛期河水暴涨，水资源丰富;冬春季风从大陆吹来，降水少，河流进入枯水期，严重缺水。)(2)从空间分布来看，空间分布不均，因为降水南方多北方少，河湖分布南方稠密北方稀疏。(由于南方雨季开始早，结束晚，雨季长，河流汛期长，水资源丰富，北方雨季开始晚，结束早，雨季短，河流汛期短，水资源不足。) 1)(2)见课本，补充(3)我国水资源年际变化大，导致旱涝不均，需要修建水利影响:( 工程。 活动 2. 答:水利工程的建设，可以缓解我国水资源的时空分布不均带来的矛盾。(1)修建水库，可以解决水资源季节变化大的问题;(2)跨流域调水，可以解决水资源空间分布不均的问题。例如我们济南:水库有卧虎山、锦绣川、鹊山等，解决水资源季节分布不均和年际变化大问题，保障城市供水。(黄河堤坝，可以防洪。) 活动 3. 答:提示:三峡工程将可以调节长江水量的季节变化，解决长江水季节分配不均的 问题，同时还兼有防洪、航运、灌溉、养殖、旅游等功能。南水北调工程将可以缓 解我国水资源南多北少的矛盾。参见课本P79。 -------------------------------------------------------------------------------------------------------------------- P82 活动 1. 答:提示:我国的水资源从总体上看，一方面水资源的供应相当紧张，缺水状况在继续加重;另一方面却是水资源的利用率低，浪费惊人;此外，水污染也严重影响了水资源的可利用价值，进一步加剧了我国的缺水程度。所以，节约用水、保护水资源是解决我国缺水问题的重要途径之一。 水价上涨是“节约用水”的政府措施，原因是:水价偏低，是造成水资源浪费的原因之一，水价应该体现水资源的价值。影响是:水价上涨，增加了居民的生活开支。 活动 2.答: 略。培养节水意识。 活动3: 了解课本提供的资料，熟悉家庭节约用水的主要措施，知道什么情况或问题下使用这些资料。 -------------------------------------------------------------------------------------------------------------------- 第四章 中国的经济发展 第一节 逐步完善的交通运输网 should be tightened, no loose, Terminal Board wiring should be one on each side, no more than two.
