Questions 81-90 are based on the following passage. It sounds like a science fiction, but researchers say it’s a scientific fact: Microscopic organisms dubbed "killer algae" are paralyzing fish with unknown toxins and then eating away at their flesh. They might be making people sick, too. The name given to this single-cell organism, or dinoflagellate, is Pfiesteria piscimorte- literally, "fish killer. " It was discovered at North Carolina State University in 1988, but at the same time, few scientists believed in its existence, much less in its highly unusual predatory nature. But ongoing research has led to international acknowledgment of the phenomenon and, recently, research funding. Seemingly prompted by an unknown substance secreted by fish, the aggressive creature swims into action. It sends neurotoxins into the water and air, paralyzing a fish’s nervous system, and causing it to gasp for air at the surface. Eventually the fish suffocates. The killer dinoflagellate then attaches itself to the fish and begins sucking away at its flesh. This macabre scenario may help solve several sea mysteries, such as why fishermen report seeing "fish walks" (fish trying to leave the water) and pools of dead fish with holes eaten through them. Whether humans are affected by the dinoflagellate’s toxin remains to be seen. Researchers think it’s unlikely eating fresh fish are in danger, but anyone with frequent exposure to the creature could be in peril. Several researchers working with the algae have reported bouts of memory loss and disorientation. To understand the killer algae further, scientists must fully characterize their toxin and determine what stimulates them to attack. They also need to know if the algae are hurting fish populations, and whether pollutants make them more likely to attack. The word "they" underlined in Paragraph 1 refers to ______.
A. organisms
B. fish
C. toxins
D. flesh
200×年×月×日13时26分,某市某化学危险品仓库发生特大爆炸事故。爆炸引起大火,1小时后着火区发生第二次强烈爆炸,造成更大范围的火灾。直到6日凌晨5时,才扑灭这场大火。这起事故造成15人死亡,200多人受伤(其中重伤25人),直接经济损失超过2.5亿元,已经威胁到某市的安全。 经事故调查,专家组认定将干杂仓库违章改作化学危险品仓库以及仓库内化学危险品违章存放是事故的主要原因;干杂仓库4#仓内混存的氧化剂和还原剂接触是事故的直接原因。“8.5”特大爆炸火灾事故是一起严重的责任事故。 事故的间接原因是: (1)某市城市规划忽视安全要求。市政府某些工作人员安全意识薄弱,对该仓库区的总体布置未按国家规定进行审查,造成易燃、易爆、剧毒化学危险品仓库、牲畜和食品仓库以及液化石油气储罐等设施集中设置,并且其与居民区和交通道路之间均不符合安全距离的规定要求。 (2)不按国家有关安全规定对该危险物品储运公司的申办报告进行严格审查,就批准成立某危险物品储运公司,属失察失职。 (3)作为民用爆炸物品发放许可证的政府主管部门,某市公安局执法不严,监督不力。未按规定严格审查,便向该公司颁发许可证,使其在不具备国家规定安全条件情况下,经营民用爆炸物品合法化。 (4)该危险物品储运公司是中国对外贸易开发集团下属的储运公司与市公安局派出的爆炸危险物品服务公司联合投资建立的,对消防及化学危险品负有监督职能的市公安局未能严格执行双重性监督职能,为其下属单位经营开方便之门。 (5)该公司凭借与公安局的特殊关系,长期违反化学危险品的安全管理规定,冒险蛮干,违章混存化学危险品,埋下祸根。 此外,该公司为获得经营化学危险品的许可,还弄虚做假,欺骗上级机关。 根据以上内容回答下列问题。 1.简述重大危险源的概念。 2.试分析该仓库存在的危险危害因素有哪些应采取哪些措施来控制危险危害因素转化为事故 3.直接经济损失的统计范围是什么间接经济损失的统计范围是什么 4.这起事故是否构成特别重大事故 5.试给出这起事故的经验教训。
