答案与解析：
46.E。本文的标题是Heat Is Killer，通篇文章说的是heat的危害性及预防方法。空白处前面的句子说“Floods，storms，volcano eruptions and other natural events kill thousands of people every year”，空白处后面的句子说“…heat may be nature’S deadliest killer”。将两个句子所表达的意思汇总来看，floods，storms，volcano eruptions和高温都是杀手，而以高温更甚。空白处的句子一定与“杀手”有关。六个选项中只有E符合这个条件，所以E是答案。
47.D。空白处后面的句子说到heat waves，而选项D的句子中也出现heat wave，说明这两个句子意思上有联系。空白处中的句子应该是对“heatwave”下的'定义，以便为下一句的展开作铺垫。故D是答案。
48.F。第一段末尾说：热浪期间，当黑夜与白天温差不大时，对人体伤害很大。第二段就列举了许多保护自己免受高温伤害的方法。空白处的句子应该是位于段首的概括句。选项F说人们有多种办法保护自己，完全符合要求，因此F是答案。
49.C。紧跟该空白处后面的句子中有特指的the pain，说明前文一定出现过pain这个词。选项C的句子中有pain，且C的句子填入后，上下文意思连贯，所以c是答案。
50.A。空白处前面的句子说：某些人在热浪期间特别危险。读者或许会问，是哪些人呢?选项A回答了这个问题，所以A是答案。
