as we know , water is very important to man, we can’t live without water. the amount of water which is suitable to drink is less and less. but some people don’t care about it .they waste a lot of water in their daily life. even worse, they pour dirty water in to rivers. they throw rubbish into rivers , too. many rivers and lakes are seriously polluted.something must be done to stop the pollution. only in this way can we live happily. if we don’t save water, the last drop of water will be a tear-drop of us.
we know that despite the fact that seventy percent of the earth's surface is covered with water, only a little part of it is fresh water. yet the demand for fresh water in our daily life and in industry seems great. moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. it is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. what is worse, more and more water resources are being polluted, making the water unfit to use.
in addition,we must warn the people of the importance of water and the danger we are facing.for example, in most asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet. furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.
一走进冰雪大世界,各种风格的冰雕建筑,各种卡通的冰雕人物……映入我们的.眼帘。看,那一座座小塔,五彩斑斓,形状各异;那一座座大宫殿,巍峨壮观,光彩夺目;那一个个栩栩如生的卡通人物也来参加了晚会。我最喜欢的是那座78米高的大白塔。他外面是一层冰。里层是空心的并且布满了蓝色的灯管,真雄伟。塔顶有一台高功率的激光灯,射出一束束醒目的白光。塔下还有一座冰灯广场。十几座小塔围绕一圈,往外是一层层散发出不同颜色的台阶,真美!
冰雪大世界不但有魅力的冰灯建筑物,而且还有很多冰上游戏。城堡滑梯就是最刺激好玩的。又高又陡的滑道,一开始我有点害怕,可是后面排了很多人,我又不能不滑下去,所以咬咬牙,小心地坐下来,两脚劈开,用脚抵着冰护栏,想着可以刹车。可是,冰太滑了,没等坐稳,我就四脚朝天躺着溜了出去,我情不自禁地喊到:“啊――”滑下去后,感觉自己的小心脏都要跳出来了,真刺激!
这次东北之行,我看到了最美的雪景,玩了很多不一样的游戏,也了解了东北三宝、东北八大怪等民俗文化,这次旅游就像妈妈说得:很值得!
7月27日告别南方炎炎夏日,我们一家三口和朋友搭上海南航空飞机来到素有“冰城”、“天鹅项下的珍珠”以及“东方小巴黎”之美称、具有异国情调的美丽城市——哈尔滨。在清风细细雨中我们游览了哈尔滨市著名的太阳岛和圣·索菲亚教堂。
先让我为你们介绍一下圣·索菲亚教堂吧:圣·索菲亚教堂于哈尔滨市内,是远东地区最大的东正教堂,通高53。35米,占地面积721平方米,是拜占庭式建筑的典型代表。墙体是全部采用清水红,红上冠世大饱满的洋葱头穹顶,统率着四翼大小不同的帐蓬顶,形成主从式的布局。在教堂的入口的右边,有群鸽子,分别有灰鸽、白鸽、黑鸽,它们不时在教堂的上方不停盘旋,游客忍不住停下脚步,拿着食品喂养鸽子并与它们合影留念。
进入圣·索菲亚教堂,入口处的堂边有卖特色商品的:有可爱的套娃;有小巧玲珑的乐器模型;也有边镶小钻石的镜子;各种商品都琳琅满目,数不胜数。教堂中有清代风格的文庙模型,也有拜占庭风格的圣·伊维尔教堂模型,都十分吸引游客的注意。教堂深处还有哈尔滨的历史概述,使游客不仅能了解哈尔滨的历史文化还能领略到各种欧式建筑模型。
接着,我们来到了太阳岛岛上映入眼帘的是一条不长的“列车”,这个“列车”是太阳岛的食品服务区,样子十分独特。太阳岛上有一个花园,花园中的花可多了:有紫色的熏衣草、有金色的向日葵、有红色的蝴蝶兰,也有黄色的郁金香……美不胜收,使游客朋友们应接不暇。在花园的后面有一个“冰雪大世界”,“冰雪大世界”是一个冰雕馆,我和几个朋友早已迫不及待地想去这个“冰雪大世界”里看看只有冬天才能见得着的冰雕。
当我和朋友们穿着棉大袍走进“冰雪大世界”时,突然发现膝盖下有一层层像雾似的白色气体,这时,你会感觉一种冰凉凉的东西像尖刀似的刺入你的骨头。这其实是冰雕馆的冷气,有了冷气,才可以使冰雕完好无损地保存下来。冰雕馆中有许许多多的冰雕,让人留连忘返,正当你在欣赏穿着大袍的龙王时,美丽的美人鱼,又吸引起了你的注意,正当你在和唐老鸭合影时,调皮的马小跳又进入你的眼帘,当你在欣赏雪白的羊群时,它们,会让你不禁想起美丽的大草原……站在群雕之间,仿佛身入仙境一般,栩栩如生。
走出“冰雪大世界”,你会依然沉浸在刚刚的“冰世界”中,久久不能忘怀;这时,又回想起圣·索菲亚教堂的美景,情不自禁地会赞叹起我国的美丽风景。
今年暑假,我和两个姐姐去了哈尔滨,哈尔滨是黑龙江的省会。
我们首先去了中央大街,这条街大多是俄罗斯风情建筑,纪念品商铺里卖各种各样的俄罗斯套娃,还有镜子木梳一类的小玩意。来店购买的人真是络绎不绝。当夜幕降临时,这里灯火阑珊,如同置身国外。这条街有很多富有俄式特色的小吃,奶香浓郁的马迭尔冰棍,"坚硬无比"的俄式大列巴,还有面包发酵的格瓦斯,这些都是我的`最爱。
在品尝过了这里的美食后,我们来到了索非亚大教堂,索非亚大教堂是一个欧式风格的建筑。看上去庄重典雅。广场上有好的鸽子,那些鸽子被训练的不怕人。人们把手里的面包屑喂给它们吃,鸽子的步伐怡然自得。我和姐姐买了面包喂鸽子,起初我一伸手,鸽子们呼啦一下飞过来,吓得我直往后躲。后来我不怕了,蹲在鸽群中间,与它们尽情玩耍。一旁的姐姐帮我用相机定格了这美好de时光。
这次哈尔滨之游让我不虚此行。
水是一切有机体的主要组成部分,全球动植物和40亿人体内含有约11200亿吨水。人类社会依赖水而生存发展。古代,人类对水取利避害,适应水而生存;近代,人类对水兴利除害,兴建工程,开发水利,控制水害;现代,随着社会和生产的发展,地球上可资利用的水日趋短缺,水体受到污染,严重影响人类生存的环境,人类逐渐认识到水是一种重要资源和环境因素,从而在更高的水平上开始对水开展了新的兴利避害活动。
世界气象组织1996年初指出:缺水是全世界城市面临的首要问题,估计到2050年,世界2/3以上的人口将生活在城市,而全球有46%的城市人口缺水,必须平衡社会经济发展和城市淡水供应管理二者之间的关系,进行水资源的储存、输送和管理的大规模工程建设。
