Unit 4 The Wonders of Nature Section B 1a-1e 攀登新高 对大多数人来说，珠穆朗玛峰是世界上最伟大的奇观之一。在地球上最高的地方，你会感觉自己仿佛能够触摸到天空。但只有最优秀的登山者才能登顶，而且前提是他们必须先在那可怕的环境中存活下来。在山峰上，气温可降至零下30度。登山者还必须应对稀薄的空气、高耸的悬崖和多变的天气。 1960年之前，没有人能够从北坡登顶珠穆朗玛峰。登山者甚至把那一条路叫做“死亡之路”，但一支中国登山队下定决心要完成这次攀登。 1960年5月24日，登山者刘连满、王富洲、屈银华和贡布抵达了“第二台阶”。那里海拔8600米。人们说那里高得连鸟儿都飞不到。刘连满让队友踩在他的肩膀上。一点一点地，登山者们向上攀爬，他们成功越过了第二台阶。1960年5月25日凌晨4点20分，五星红旗第一次在世界最高峰的上空飘扬。 1975年，另一支中国登山队登顶珠穆朗玛峰进行科学研究。这一次，他们把一架梯子带到了第二台阶。直到2007年，几乎所有从北坡攀登的登山者都使用这架“中国梯”更快地登顶。2020年，第三支队伍重返珠穆朗玛峰，测量了它的高度——8848.86米。 攀登珠穆朗玛峰是危险的。有些登山者成功登顶，但很多人失败了。为什么人们仍然冒着生命危险去攀登世界最高峰？这是因为人类的好奇心和雄心无法被阻止。或者，正如英国探险家乔治·马洛里所说，仅仅“因为它就在那里”！ high cliffs fall to -30 degrees changeable weather thin air Determination Reaching New Heights What do you want to know about the passage?
