题目内容
某储运公司仓储区占地300 m×300 m，共有8个库房，原用于存放一般货物。3年前，该储运公司未经任何技术改造和审批，擅自将1号、4号和6号库房改存危险化学品。2008年3月14日12时18分，仓储区4号库房内首先发生爆炸，12分钟后，6号库房也发生了爆炸，爆炸引发了火灾，火势越来越大，之后相继发生了几次小规模爆炸。消防队到达现场后，发现消火栓不出水，消防蓄水池没水，随后在1公里外找到取水点，并立即展开灭火抢险救援行动。事故发生前，1号库房存放双氧水5 t；4号库房存放硫化钠10 t、过硫酸铵40 t、高锰酸钾10 t、硝酸铵130 t、洗衣粉50 t；6号库房存放硫磺15 t、甲苯4 t、甲酸乙酯10 t。事故导致15人死亡、36人重伤、近万人疏散，烧损、炸毁建筑物39000 m2和大量化学物品等，直接经济损失1.2亿元。 根据以上场景，回答下列问题(1～3题为单选题，4～7题为多选题) 本案中，第一次爆炸最可能的直接原因是( )。

Not so fast, some researchers say. Additional warming would be certain (6) nothing else in the climate system changes. And the climate system is (7) static. Some combinations of changes could reinforce the heating; others could (8) it.

某企业有玻璃器皿生产车间。该企业的玻璃器皿制造分为烧制玻璃熔液、吹制成型和退火处理三道主要工序，烧制玻璃溶液的主要装置是玻璃熔化池炉。烧制时，从炉顶部侧面人工加入石英砂(二氧化硅)、纯碱(氢氧化钠)、三氧化二砷等原料，用重油和煤气作燃料烧至1300～1700℃，从炉底侧面排出玻璃熔液。玻璃器皿的生产车间厂房为钢筋混凝土框架结构，房顶是水泥预制板。厂房内有46t玻璃熔化池炉1座，炉高6 m，炉顶距厂房钢制房梁1.7 m，炉底高出地面15 m。距炉出料口3 m处是玻璃器皿自动吹制成型机和退火炉。煤气调压站距厂房直线距离15 m，重油储罐距厂房直线距离15 m。车间内有员工20人正在工作。由于熔化池炉超期服役，造成炉顶内拱耐火砖损坏，烈焰冲出炉顶近1 m，炉两侧的耐火砖也已变形，随时有发生溃炉的可能。2008年6月11日，当地政府安全生产监督管理部门在进行监督检查时；发现该炉存在重大事故隐患；当即向企业发出暂时停炉、停产的指令。 根据以上场景，回答下列问题 针对该企业现状，提出防范生产安全事故的建议。

Text 4 In a paper just published in Science, Peter Gordon of Columbia University uses his study of the Piraha and their counting system to try to answer a tricky linguistic question. The Piraha, a group of hunter-gatherers who live along the banks of the Maiei River in Brazil, use a system of counting called "one-two-many". In this, the word for "one" translates to "roughly one" (similar to "one or two" in English), the word for "two" means "a slightly larger amount than one" (similar to "a few" in English), and the word for "many" means "a much larger amount". This question was posed by Benjamin Lee Whorl in the 1930s. Whorl studied Hopi, an Amerindian language very different from tile Eurasian languages that had hitherto been the subject of academic linguistics. His work led him to suggest that language not only influences thought but, more strongly, that it determines thought. While there is no dispute that language influences what people think about, evidence suggesting it determines thought is inconclusive. For example, in 1972, Eleanor Rosch and Karl Heider investigated the colour-naming abilities of the Dani people of Indonesia. The Dani have words for only two colours.- black and white. But Dr. Rosch and Dr. Heider found that, even so, Dani could distinguish and comprehend other colours. That does not support the deterministic version of the Whorl hypothesis. While recognising that there are such things as colours for which you have no name is certainly a cognitive leap, it may not be a good test of Whorf’s ideas. Colours, after all, are out there everywhere. Numbers, by contrast, are abstract, so may be a better test. Dr. Gordon therefore spent a month with the Piraha and elicited the help of seven of them to see how far their grasp of numbers extended. The tests began simply, with a row of, say, seven evenly spaced batteries. Gradually, they got more complicated. The more complicated tests included tasks such as matching numbers of unevenly spaced objects, replicating the number of objects from memory, and copying a number of straight lines from a drawing. In the tests that involved matching the number and layout of objects they could see, participants were pretty good when faced with two or three items, but found it harder to cope as the number of items rose. Things were worse when the participants had to remember the number of objects in a layout and replicate it "blind", rather than matching a layout they could see. In this case the success rate dropped to zero when the number of items became, in terms of their language, "many". And line drawing produced the worst results of all--though that could have had as much to do with the fact that drawing is not part of Piraha culture as it did with the difficulties of numerical abstraction. Indeed, Dr. Gordon described the task of reproducing straight lines as being accomplished only with "heavy sighs and groans". It is suggested in the third paragraph that
