Heat Is Killer
Extremely hot weather is common in many parts of the world. Although hot weather just makes most people feel hot, it can cause serious medical problems -- even death. Floods, storms, volcano eruptions and other natural disasters kill thousands of people every year. 1 Experts say heat may be nature's deadliest killer. Recently, extreme heat was blamed for killing more than one hundred people in India. It is reported that the total heat of a hot day or several days can affect health. 2 Experts say heat waves often become dangerous when the nighttime temperature does not drop much from the highest daytime temperature. This causes great stress on the human body.

synthetic adj. 合成的
注釋：
1．Make sure the clothing is loose．permitting freedom of movement：衣服一定要寬松，以便活動自如。make sure意為“確信，保證”，其后面從旬的謂語要用一般現(xiàn)在時1。如：Make sure the door is locked before you leave。permitting freedom of movement是分詞短語，用作目的狀語。
2．The pain is a warning that the body is becoming too hot：疼痛是一個警告，說明你的身體過熱。that the body is becoming too hot是同位語從句，與warnin9同位，說明warnin9的內容。
3．physical activity：體力活動
4．Hot weather also increases dangers for people who must take medicine for high blood pressure…：炎熱天氣對于那些必須服藥以控制血壓的人……也增力n-J"危險性。

答案與題解：
1．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l”前面的句子說，“Floods，storms，volcano eruptions and other natural events kill thousands of people every year”，“空l”后面的句子說，“…heat may be nature’s deadliest killer”。將兩個句子所表達的意思匯總來看，floods，storms，volcano eruptions和高溫都是殺手，而以高溫更烈。“空l”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。
2．D“空2”后面的句子說到heat waves，而選項D的句子中也出現(xiàn)heat wave，說明這兩個句子意思上有聯(lián)系。“空2”的句子是對“heat wave”下定義，為下一句的展開作了鋪墊。D是答案。
3．F第一段末尾說，熱浪期間，當黑夜與白天溫差不大，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3”的句子應該是位于段首的概括句。選項F說人們有多種辦法保護自己，完全符合要求，因此是答案。
4．C緊跟“空4”后面句子中有特指的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，且C的句子填人后，上下文意思連貫，所以是答案。
5．A“空5”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，所以是答案。
