Heat is Killer

Extremely hot weather is common in many parts of the world. Although not 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.

3 . Stay out of the sun, if possible. Drink lots of cool water. Wear ligh colored clothing made of natural materials; avoid wearing synthetic clothing. Make sure the clothing is loose, permitting freedom of movement. And learn the danger signs of the medical problems, such as headache and vomiting, that are linked to heat.

4 . The pain is a warning that the body is becoming too hot. Doctors say those suffering headache or musle pain should stop all activity and rest in a cool place and drink cool liquids. Do not return to physical activity for a few hours because more serious conditions could develop.

Doctors say some people face an increased danger from heat stress. 5 .

Hot weather also increases dangers for people who must take medicine for high blood pressure, poor blood flow, nervousness or depression.

答案: 1. E 2. D 3. F 4. C 5. A

1.E 本文的标题是Heat is Killer，通篇文章说的是高温危害性和预防办法。根据“空1”前面的句子，可以知道，“每年数以万计的人死于洪水、风暴、火山喷发和其它自然灾害。”由此可以顺理成章地推理出来，“极热天气也是如此。”所以选择E。

2.D “空2”后面的句子说到“heat waves”(热浪)，而选项D的句子中也出现“heat wave”，说明这两句话意思有联系。“空2”的句子对“heat wave”下定义，是下一句的展开铺垫。所以，选择D。

3.F 第一段末尾说，白天的热浪，如果到夜晚没有一定幅度的下降，那会给身体带来巨大压力，这是很危险的。第二句话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(或者说是“主体句”)。选项F说人们有很多方法保护自己，完全符合要求，因此是正确答案。

4.C 紧跟“空4”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”这个词，而且C句子填入后，上下文意思连贯，所以是答案。

5.A “空5”前面的句子意思是：某些人在热浪期间健康可能会面临很大的危险。A选项明确回答了这个问题，即“那些人在热浪期间健康会面临危险。”
