Mountain climbing is becoming a popular sport, but it is also a【B1】_____ dangerous one. People can fall; they may also become ill. One of the most common dangers to climbers is altitude sickness, which can affect even very【B2】_____ climbers.
Altitude sickness usually begins when a climber goes above 8,000 or 9,000 feet. The higher one climbs, the less oxygen there is in the air. When people don’t get enough oxygen, they often begin to【B3】_____ for air. They may also feel【B4】_____ and light-headed. Besides these symptoms of altitude sickness, others such as headache and【B5】_____ may also occur. At heights of over 18,000 feet, people may be climbing in a【B6】_____daze (恍惚). This state of mind can have an【B7】_____ effect on their judgment.
A few【B8】_____ can help most climbers avoid altitude sickness. The first is not to go too high too fast. If you climb to 1 0,000 feet, stay at that height for a day or two. 【B9】______. Or if you do climb higher sooner, come back down to a lower height when you sleep. Also, drink plenty of liquids and avoid tobacco and alcohol. 【B10】______. You breathe less when you sleep, so you get less oxygen.
The most important warning is this: if you have severe symptoms and they don’t go away, go down! 【B11】______.
【B7】
