组织一次旅游。简要叙述过程。
参考答案：这道题考的是你的组织协调能力。首先通过一定的方式比如民主方式确定本次旅程的目的地、资金来源、行程安排。最好考察当地的自然环境，看看是否存在某些隐患或突发性的安全问题。这些准备工作即使不需要很确切，也要有个大概的计划以供讨论和修改。如果上述计划基本确定，资金到位，可以开始确定某项工作具体有谁负责，比如交通、安全、食宿，将工作分解成几部分，各有专人负责。上述准备工作基本就绪之后，可以启程。
People who are outdoors in cold weather should avoid actions like suddenly lifting a heavy basket full of snow. Even walking through heavy, wet snow can strain a person’s heart. Many people aren’t conditioned to the physical stress of outdoor activities and don’t know the dangers of being outdoors in cold weather. Those who like winter sports can suffer accidental hypothermia if they don’t make certain preparations. Hypothermia means the body temperature has fallen below normal. It occurs when your body can’t produce enough energy to keep the internal (内部的) body temperature warm enough. It can kill you. Heart failure causes most deaths in hypothermia. Children, the elderly and those with heart disease are at special risk. As people age, their ability to keep a normal internal body temperature often decreases. Elderly people can suffer hypothermia without knowing they’re in danger because they can’t notice the cold conditions as quickly as the young. Besides cold temperatures, high winds, snow and rain can also steal body heat. Wind is especially dangerous because it removes the layer of heated air from around your body. At 30 degrees Fahrenheit in a 20-mile-per-hour wind, the cooling effect is equal to calm air at four degrees. Similarly dampness (湿气) causes the body to lose heat faster than it would at the same temperature in drier conditions. To keep warm, wear more clothes. This traps air between layers. Also, wear a hat or head scarf. Much of your body’s heat can be lost through your head. Keep your hands and feet warm, too, as they tend to lose heat rapidly. Don’t drink alcohol before going outdoors or when outside. Alcohol makes you feel warm at first because blood vessels in the skin expand. But heat is then drawn away from the body’s important organs. 1. The underlined word “strain” in Paragraph 1 means ________. A. injure B. warm C. control D. burn 2. What is implied in the passage about hypothermia?
