Mountain climbing is becoming a popular sport, but it is also a potentially dangerous one. People can fall. They may also become ill.
登山成了一項受歡迎的運動，但是它也是一項具有潛在危險的運動。人們可能會跌落或生病。
One of the most common dangers to climbers is altitude sickness, which can affect even very experienced climbers. Altitude sickness usually begins when a climber goes above 8,000 to 9,000 feet. The higher one climbs, the less oxygen there is in the air.
其中最常見的危險是高原病，即使是很有經驗的登山者也會受影響。高原病通常在登山者爬到八千到九千英尺以上的時候出現。一個人爬得越高，空氣中的氧氣就越少。
When people don't get enough oxygen, they often begin to gasp for air. They may also feel dizzy and light-headed. Besides these symptoms of altitude sickness, others such as headache and fatigue may also occur.
當人們沒有足夠的氧氣時，他們經常會變得氣喘吁吁，或頭暈目眩。除了這些高原病反應外，頭痛、疲勞的狀況也可能發生。
At heights of over 18,000 feet, people may be climbing in a constant daze. Their state of mind can have adverse affect on their judgment.
在18,000英尺以上的高度，人們可能會在攀登中感到陣陣暈眩。他們的精神狀態會影響他們的判斷力。
A few precautions can help most climbers avoid altitude sickness. The first is not to go too high, too fast. If you climb to 10,000 feet, stay at that height for a day or two. Your body needs to get used to a high altitude before you climb to a even higher one.
一些預防措施可以幫助多數攀登者抵抗高原病。首先是不要攀登的過高、過快。如果你爬到10,000英尺了，在那個高度休息一、兩天。在你攀登更高的高度之前，你的身體需要適應。
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.
或者如果你很快爬到了更高的山峰，睡覺的時候爬到下面低點的高度休息。另外，多喝液體，避免抽煙、喝酒。
When you reach your top height, do like activities rather than sleep too much. You breathe less when you sleep, so you get less oxygen.
當你抵達你的預期高度時，多做運動，不要總睡覺。睡覺的時候，你的呼吸會變緩，吸入的氧氣也隨之減少。
The most important warning is this: if you have severe symptoms, then don't go away, go down. Don't risk injury or death because of over-confidence or lack of knowledge.
最重要的警告是：如果你有嚴重的癥狀出現，不要再走了，往下爬。不要因為過于自信或缺少知識而冒生命危險。
