it is well-known that water is indispensable in existing, in producing and in living. and we should
not waste of a drop of water.
众所周知,在生产和生活中水是必不可少的。我们不应该浪费一滴水。
first, water is definitely important for life. as is known to us all, water is necessary to sup
port life. without water, human beings, animals and plants cannot exist at all.
首先,水对生命是非常重要的。众所周知,水是维持生命所必需的。没有水,人类,动物和植物都不复存在。 second, water is also significant for producing. for one thing, industrial production needs a lot of water, such as using water to generate electricity. for another, agricultural production is also in need of water, especially in irrigation.
Up a slightly-left-of-center masterpiece. The emotional impact of the beautiful, wordless summation of Carls life that opens the movie the bass note that resonates through the whole film and at least as affecting as the scene in Wall-E when he holds h own hands while watching Hello Dolly. The rest of the movie, of course, breathtaking on just about every level, especially the tactile quality of all the characters and textures and the completely realized weather effects and action scenes. With no "new" technical milestones (fur in Monsters, Inc., water in Finding Nemo, realtic camera effects in Wall- E, the design the main focus, from the hilariously stylized characters to the amazing setting of the tepui.
I know----thats a interesting trip!
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。

我原本对邮票不感兴趣,但自从我妈妈给我看了她的集邮册后,我对邮票顿时产生了浓厚的兴趣。渐渐地,我也集了好几张邮票呢!有人物的,有风景的,有生肖……然而我最喜欢的,是一张以竹子为主题的邮票。
这是我七岁时得到的邮票,我用一辆汽车模型和一个大哥哥换来的。邮票是长方形,但是外边有像波浪一样的锯齿。图中右上角印着小小的“CHINA”,左下角有“中国邮政”四个字,“中国邮政”旁边有一个大大的“30分”,左上角是一个淡淡的印章。图画正中下面有着很小很小的“金镶玉竹”的字,左边是“1993-7”的数字。一说,似乎占了很多的空间。但这些字与图“水火不相容”,谁都没有阻碍到谁。
瞧,邮票的正中间是两根竹子相互交错,一节一节挺拔的竹竿,又有一点曲折,真像一幅美丽的风景图。而竹叶画得栩栩如生,绿油油的,似乎风一吹,竹叶就会随风飘动。后面还有淡淡的黑色的影子,与真体没什么差别,但方位不同。印的这么真,正是因为这点吸引了我。
说到竹子,我不禁想到了它的用途和品质。
竹子全身上下都是宝。竹叶可以当药,让生病的人慢慢恢复;竹笋可以吃,美味、健康;竹竿切成条可以做竹席,还可以做竹桶、笛子、竹扫帚和竹篱笆……总之,竹子是个宝。这张邮票选竹子,肯定因为它对人类的贡献。
“岁寒三友”、“四君子”之中就有讲到竹。中国传统中,竹子象征着生命的弹力、长寿、幸福和精神真理。“门对千棵竹,胸装万卷书”竹子空心,象征谦虚,虚心能自持;“千磨万击还坚劲,任尔东西南北风”竹的特质宁折不弯,不畏风雪;竹节必露,竹梢拔高,比喻高风亮节。它文静、高雅;虚心、气节;无私奉献、与世无仇。邮票上的竹子,两根竹子,一根挺拔地生长,一根竹节略显曲折。竹子虽然曲折了,但它还是依然竖立在山中,不放弃、不气馁。竹子无私地把它的所有东西奉献给了人类,自己却不索取回报;多么谦虚的竹啊!这就是竹子它的品格。
竹,它的品格好,它的用途广,它的模样美。我想,这张邮票印竹,是有它的原因吧。
如果一座没有历史文化底蕴的城市,新盖的建筑物再多,也是苍白的。上海的老房子是城市深厚历史文化底蕴的组成部分。作为世界历史文化名城之一的上海,不能没有老房子,就如不能没有历史文化那样。上海老房子随着城市的辟路、建地铁、造桥、盖新楼、造各种商场等一批批消失了,存下的老房子越来越少了。
一个老房子里可以有什么?一段往事,一段童年的回忆?还是长大的无奈?
走进富有上海气息的弄堂里,眼前的小路使我不经意间产生几许凄凉之感。四处湿嗒嗒的,墙角长了不少的青苔,斑驳,剥落的墙面透露出时光流逝的沧桑感。我也曾想过,如果老房子知道它现在已经被人遗忘了,会不会也躲在黑暗里默默地哭泣呢?好在现在老房子里住的人还不少,更多的是一些老人不愿意搬出来,毕竟这里有几代人留下的回忆。
走过略微阴暗的弄堂,再来就进入人们住的老房子了。给我印象最深刻的还是它的结构。
首先是石库门和天井最先映入眼帘,然后便是客堂间,旁边是厢房。跨过窄小的过道就是楼梯间。底楼的房子后面会设置一个灶间,年代久远点的时候里面会有很多只灯泡用来照明。每户人家备一只灯泡,这么多家住户把灯泡放在一起,像极了一串会发光的葡萄。灶间的旁边还有个大水槽,是水泥砌成的,大约有半腰高,大家都依靠它来做最基本的洗漱。伴随人居增多,水龙头密布。
灶间往上就是亭子间了,亭子间设在底楼与二楼或二楼与三楼之间,大多处在厨房上面和楼梯转折处,也有在顶层,室内低矮局促。所谓“亭子间”,原意是储藏室,近乎阁楼的性质,大多为佣人仆人的栖身之处,冬受风欺,夏为日,只有一边墙上开窗,面积绝对小于十平方米。这种狭小的环境换了现代人更本就住不下去!很多作家都写过关于亭子间的小说,把它描绘的如梦幻场景一样。但在我看来即使狭小凌乱这也是它最真实的样子。
沿着亭子间旁的楼梯往上走,就是为数不多的正房,那是一栋石库门中最好的居住环境了。随后要说到阁楼。随着人口的增加,有许多孩子睡觉其实是在阁楼上的,相比之下阁楼的空间也不大,但是不得不提的还是老虎天窗。在夏日炎热的晚上,睡不着的孩子们是有多无聊多难耐啊,他们掰着手指头望着深蓝色的夜空数着星星,那份少年时纯真的情感多让人动容!
顶楼的后面还有晒台,夏天的傍晚时这绝对是个纳凉聊天的好去处!老老少少,在夏日余晖中的那点光亮里,老人摇着蒲扇讲故事,孩子托着腮帮听故事,不远处甚至还传来老式收音机里那悠悠的戏曲唱腔和说词对白。这份惬意这段画面,实在是永生难忘!
老房子的历史悠久,建筑结构独特。承载了一代又代人的童年和美好的记忆。总而言之,那些有着自己独特风格而非现代化钢架混凝土工艺,无论怎样都有无法比拟的意义不是么?我觉得老房子不该拆,它应该切实的存在着……它是城市的一部分也是历史的一部分。
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.
