答案与题解：
1.E本文&标题是Heat Is Killer,通篇文章说的是heat的危害性及预防方法。“空1”前面的 句子是，"Floods，storms,volcano eruptions and other natural events kill thousands of people every year"，“空 1”后面的句子是，“…heat may be nature's deadliest killer”。所以这里应将最致命的杀手E提出。
2.D “空2”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2”的句子是对“heatwave”下定义，为下一句的展开作了铺垫。D是答案。
3.F第一段末尾说，白天的热浪，如果到夜晚没有降温，会给身体带来巨大压力，这是很危险 的。第二段就列举了许多保护自己免受高温伤害的方法。“空3”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，因此是答案。
4.C紧跟“空4”后面句子中有特指的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，所以是答案。
5.A “空5”前面的句子意思为：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，所以是答案。
