答案與解析：
46.E。本文的標題是Heat Is Killer，通篇文章說的是heat的危害性及預防方法。空格前面的句子說，“Floods，storms，volcano eruptions and other natural events kill thousands of people every year”，空格後面的句子說，“…heat may be nature’S deadliest killer”。將兩個句子所表達的`意思彙總來看，floods，storms，volcano eruptions和高溫都是殺手，而高溫更甚。空格的句子一定與“殺手”有關。五個選項中只有E符合這個條件，所以E是答案。
47.D。空格後面的句子提到heat waves，而選項D的句子中也出現heat wave，說明這兩個句子在意義上有聯絡。空格中的句子應該是對heat wave下的定義，以便為下一句的展開做鋪墊。故D是答案。
48.F。第一段末尾說：當黑夜與白天溫差不大時，熱浪對人體傷害很大。第二段就列舉了許多保護自己免受高溫傷害的方法。空格中的句子應該是位於段首的概括句。選項F說人們有多種辦法保護自己，完全符合要求，因此F是答案。
49.C。緊跟該空格後面的句子中有特指的the pain，說明前文一定出現過pain這個詞。選項C的句子中有pain，且C的句子填入後，上下文意思連貫，所以C是答案。
50.A。空格前面的句子說：某些人在熱浪期間特別危險。讀者或許會問，是哪些人呢?選項A回答了這個問題，所以A是答案。
