给定资料1中谈到“大量侵害公共利益的水污染事故引起的纠纷没有进入司法程序”，请依据给定资料，分析造成这种现象的原因。
要求：分析合理，条理清晰，语言简练。字数在250宁左右。
参考答案：首先，对侵害公共利益的水污染事故提起公益诉讼，面临缺乏明确法律规定的障碍。目前缺少对水污染公益诉讼的诉权进行规范的专门条款。
其次，水污染具有流域性特点，污染与损害分散在多个行政区域。大量的水污染事故涉及级别管辖与地域管辖问题，司法保护的实际操作存在诸多难题。
第三，水污染事故存在着调查取证难度大、不易操作、损害程度认定和评估制度不健全等问题，目前又缺少能胜任举证责任和鉴定技术的独立中介组织和环保机构，很多水污染直接受害人不愿意也很难诉诸司法程序。
阅读下列短文，根据短文中的信息完成文后表格。（每空一词） Hi, Daming, You ask me about how to improve（提高） your English listening. Here are some advice(建议). I hope they can help you. ◆Relax(放松) yourself. Before you start listening to something, don’t get excited or nervous（紧张的）.You need to relax．This will help you with your listening. ◆Listen carefully to the first sentence. The first sentence tells a lot about the whole passage．For example，if，at the beginning，you hear “Our reporter says…”,you know you will hear a piece of news，not a children’s story, or a science report. ◆ Think when you’re listening. When you’re listening, try to do some thinking．For example, you can think of the following questions: When, where and how? What does the speaker want to tell us? In this way, you may understand the passage better. ◆Listen to important facts. It’s important for you to remember some important facts. For example, if the passage is a science report, you should try to remember its findings, and how the scientists get their results. This is also very helpful to your listening． Yours, Tom
