Qomolangma—the Most Dangerous Mountain in the World
One of the world's most dangerous sports is mountain climbing, and one of the most popular places for this is the Himalayas. The Himalayas run along the southwestern part of China. Of all the mountains, Qomolangma rises the highest and is the most famous. It is 8,844.43 meters high and so is very dangerous to climb.
adj. 西南的；西南方向的
one of the+形容词最高级+可数名词复数 “最……的……之一。”
该结构作主语时，谓语动词要用第三人称单数形式。
珠穆朗玛峰——世界上最危险的山
世界上最危险的运动之一是登山运动,适合登山运动的最受欢迎的地方之一是喜马拉雅山脉。喜马拉雅山脉蜿蜒于中国的西南部。在所有的山当中,珠穆朗玛峰最高且最著名。它高达8844.43米,所以爬起来非常危险。
Thick clouds cover the top and snow can fall very hard. Even more serious difficulties include freezing weather conditions and heavy storms. It is also very hard to take in air as you get near the top. The first people to reach the top were Tenzing Norgay and Edmund Hillary on May 29, 1953. The first Chinese team did so in 1960, while the first woman to succeed was Junko Tabei from Japan in 1975.
v. 包括；包含
厚的；浓的 【反义词：thin（瘦的；薄的）】
= heavily
It is +adj. + to do sth. it为形式主语，动词不定式短语为真正的主语
浓云覆盖着峰顶并且雪有可能会下得非常大。更加严峻的困难包括极冷的天气条件和巨大的风暴。当你快要到达峰顶时呼吸也很困难。
在1953年5月29日，丹增·诺尔盖和埃德蒙·希拉里是第一批到达峰顶的人。第一支中国队在1960年到达峰顶，而1975年第一位成功到达峰顶的女性是来自日本的田部井淳子。
Why do so many climbers risk their lives One of the main reasons is that people want to challenge themselves in the face of difficulties. The spirit of these climbers shows us that we should never give up trying to achieve our dreams. It also shows that humans can sometimes be stronger than the forces of nature.
v. & n. 挑战；考验
v. 达成；完成；成功
n. 力；力量
n. 自然界；大自然
面对（问题、困难等）
the force of… ……的力量/力
为什么如此多的登山者冒着生命危险去攀登珠穆朗玛峰呢 主要原因之一是人们想要在面对困难时挑战自我。这些登山者的精神向我们表明:我们决不应该放弃实现梦想的尝试。这也表明人类有时比大自然的力量更强大。
