答案: 1. E 2. D 3. F 4. C 5. A
1.E 本文的標題是Heat is Killer，通篇文章說的是高溫危害性和預防辦法。根據(jù)“空1”前面的句子，可以知道，“每年數(shù)以萬計的人死于洪水、風暴、火山噴發(fā)和其它自然災害。”由此可以順理成章地推理出來，“極熱天氣也是如此�！彼赃x擇E。
2.D “空2”后面的句子說到“heat waves”(熱浪)，而選項D的句子中也出現(xiàn)“heat wave”，說明這兩句話意思有聯(lián)系�！翱�2”的句子對“heat wave”下定義，是下一句的展開鋪墊。所以，選擇D。
3.F 第一段末尾說，白天的熱浪，如果到夜晚沒有一定幅度的下降，那會給身體帶來巨大壓力，這是很危險的。第二句話就列舉了許多保護自己免受高溫傷害的方法�！翱�3”的句子應該是位于段首的概括句(或者說是“主體句”)。選項F說人們有很多方法保護自己，完全符合要求，因此是正確答案。
4.C 緊跟“空4”后面的句子中有特指的“the pain”，說明前文一定出現(xiàn)過“pain”這個詞。選項C的句子中有“pain”這個詞，而且C句子填入后，上下文意思連貫，所以是答案。
5.A “空5”前面的句子意思是：某些人在熱浪期間健康可能會面臨很大的危險。A選項明確回答了這個問題，即“那些人在熱浪期間健康會面臨危險。”
