（4分）三十年改革开放的实践成果，六十年国家的沧桑巨变，九十年党的辉煌历程……我们正处在一个从未有过的幸福时代。在建党90周年之际，我们每一个人都怀着感慨、感激和幸福之情。

请以“晒晒咱的好日子”为主题，自拟标题，写一段60字左右的文段，讴歌时代变化，见证幸福生活。内容可从生活细节入笔，记述自己的幸福感受，憧憬生活的美好未来，以此反映老百姓的生活质量、生活方式以及思想观念等方面的变化，从不同侧面、不同角度折射伟大祖国与百姓生活的变迁。总之，通过日常生活中的美好片段、激荡奋进以及幸福收获，以小见大，见微知著，从生活的点点滴滴，晒晒咱的好日子。

患者女，20岁。因多饮、多尿16年，生长发育迟缓10年入院。患者于4岁无明显诱因开始出现多饮多尿，当时未予重视，后因症状加重遂于当地医院就诊，诊断为“1型糖尿病，糖尿病酮症酸中毒”。出院后不规律使用短效动物胰岛素（每天1～3次）治疗，每月或每年查空腹血糖（具体数值不详）和尿糖（尿糖2+～3+之间波动）。病程中曾反复出现“呕吐及晕倒”（每年发作2～3次），自行将胰岛素加量治疗后可逐渐缓解。从10岁开始，患者生长发育较迟缓，每年身高增长不明显，10岁至20岁长高约10cm，每年体重约增加1.5kg， * * 一直未发育，阴毛、腋毛未出现，月经一直未来潮。在我院门诊就诊，检查血常规示血小板331×10⁹／L，尿常规示尿糖3+、尿酮体2+，肝肾功能示丙氨酸转氨酶41.5U／L，总蛋白84.7g／L，球蛋白32.7g／L，尿酸597μmol／L，肌酐121.5μmol／L，血糖21.36mmol／L，C肽＜5.5pmol／L，门诊拟“糖尿病，生长发育迟缓查因”收住院。

（提示低血糖兴奋试验显示GH27.4μg／L；骨龄：延迟，约11岁；皮质醇水平正常。基因检测：无异常发现。）该患者的最可能的诊断考虑（）

A.1型糖尿病合并继发性生长发育迟缓

B.继发性糖尿病

C.自身免疫性多内分泌腺病综合征（APS）

D.1型糖尿病合并GH缺乏

E.1型糖尿病合并垂体功能低下

     The need to feed a growing population is putting much pressure on the world's supply of water.With

97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water

needs careful management, especially in agriculture.Although the idea of a water shortage(短缺)seems

strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural

industries experience constant water shortages.

      Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs

of water redistribution(重新分配)are very high.Not only is there the cost of the engineering itself, but

there is also an environmental cost to be considered.Where valleys(山谷)are flooded to create dams,

houses are lost and wildlife homes destroyed.Besides, water may flow easily through pipes to fields, but

it cannot be transported from one side of the world to the other.Each country must therefore rely on the

management of its own water to supply its farming requirements.

      This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores.

In the Central Valley area of southwestern USA, a huge water engineering project provided water for

farming in dry valleys, but much of the water use has been poorly managed.

      Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of

irrigation water from underground reserves.Because there is no rainfall in these areas, such reserves can

only decrease, and it is believed that fifty years of pumping will see them run dry.
