{{B}}Water{{/B}} The second most important constituent(构成成份)of the biosphere(生物圈)is liquid water. This can only exist in a very narrow range of temperatures, since water freezes at 0℃ and boils at 100℃. Life as we know it would only be possible on the surface of a planet which had temperatures somewhere within this narrow range. The earth’s supply of water probably remains fairly constant in quantity. The total quantity of water is not known very accurately,but it is about enough to cover the surface of the globe to a depth of about two and three-quarter kilometers. Most of it is in the form of the salt water of the oceans -- about 97 percent. The rest is fresh,but three-quarters of this is in the form of ice at the Poles and on mountains, and cannot be used by living systems until melted. Of the remai A. a very small amount B. a large area C. an important system D. a major source of information [简答题]
某供水公司投资一供水水源项目。为了避免售水的市场风险,在项目建设初期,与甲用户依照法定程序以价格0.35元/m3依法签订了供水合同。考虑到该供水工程建设难度较大,合同约定:若供水工程建成,则供水公司应按照合同约定价格给甲用户供水;若供水工程项目取消,则所签合同不发生任何效力。
在项目建设过程中,随着供水市场水资源紧缺,同时,又不涉及到供水线路改造,该供水公司又以0.5元/m3的价格将水全部售于乙用户。签订合同时,乙用户并不知道供水公司已与甲用户签订了供水合同。
若甲用户坚持要求供水的主张,法院是否应予以支持?
