解题思路：（1）天然纤维是自然界原有的或经人工培植的植物上、人工饲养的动物上直接取得的纺织纤维，是纺织工业的重要材料来源；合成纤维是由人工合成方法制得的，生产不受自然条件的限制；据此进行分析解答．
（2）①食品、药品、营养品、矿泉水等物质中的“钾、钙、镁、氟、硅”等不是以单质、分子、原子等形式存在，而是指元素，通常用元素及其所占质量（质量分数）来描述．
②当溶液的pH等于7时，呈中性；当溶液的pH小于7时，呈酸性；当溶液的pH大于7时，呈碱性．

（1）苎麻是一种草本植物，它的纤维可织布，苎麻布料属于
（2）①温泉水富含钾、钙、镁、氟、硅等，这里的“钾、钙、镁、氟、硅”不是以单质、分子、原子等形式存在，这里所指的“钾、钙、镁、氟、硅”是强调存在的元素，与具体形态无关．
②温泉水的pH在7.5～8.9之间，大于7，该温泉水显碱性．
故答案为：（1）天然纤维；（2）①C；②碱性．

点评：
本题考点： 有机高分子材料的分类及鉴别；溶液的酸碱性与pH值的关系；元素的概念．

考点点评： 本题难度不大，掌握天然纤维与合成纤维的特征、元素的概念、溶液的酸碱性和溶液pH大小之间的关系是正确解题的关键．
