Pre-reading
This picture shows an automatic meteorological monitoring station(自动气象观测站) on Qomolangma. What it is used for? How did scientists get it there?

While reading
With heavy winds, low oxygen (氧气) and -25 C temperatures, Qomolangma is one of the hardest mountains to climb. Despite the difficulty, Chinese researchers successfully reached the top of the mountain on May 4. They also set up the world’s highest automatic meteorological monitoring station (自动气象观测站), at an altitude (海拔) of 8,830 meters.
climb [klaɪm] : v .  攀登; 爬; 攀岩; 攀缘生长;
翻译：在大风、低氧和零下25摄氏度的温度下，珠穆朗玛峰是最难攀登的山峰之一。
练习：他深吸了一口气，然后开始爬楼梯。
He took a deep breath and began to climb the stairs.  

“The new station is the highlight (亮点) of this scientific trip,” noted Guangming Daily. It replaces Balcony Station, set up by United States and British scientists, as the highest weather station on Earth. Balcony Station, set up on Qomolangma in 2019, sits at about 8,430 meters above sea level.
replace   [rɪˈpleɪs] ：v.  替换; 以…取代; 更新;
翻译：它取代了美国和英国科学家建立的Balcony Station，成为地球上最高的气象站。
练习：你觉得谁会代替她参加这场演出？
Who do you suppose will replace her on the show?   

Powered by solar panels (太阳能板), the new station can last for two years in bad weather. It has a satellite (卫星) communication system that can transmit data every 12 minutes. For the first time, Chinese scientists can collect data from the summit (山顶) of the world’s highest mountain.
power   [ˈpaʊə(r)] ： v.  驱动; 快速前进;
翻译：新的观测站由太阳能电池板供电，在恶劣天气下可以使用两年。
练习：这架飞机由喷气发动机驱动。
The aircraft is powered by a jet engine.
transmit [trænzˈmɪt] : v.  传输; 传送,传递; 发射; 传染;发送信号
翻译：它有一个卫星通讯系统，每12分钟传输一次数据。
练习：该设备是为向卫星发送信号而设计的。
The device is designed to transmit to satellites.  

Studying data from Qomolangma will help scientists answer important questions. For example, will the ice cap above 8,000 meters melt due to global warming? Will that affect the 10 big rivers in Asia that provide water to more than 2.5 billion people? What effect (影响) does air pollution have on the mountain? What is the ecosystem (生态系统) like 8,000 meters above sea level?
due to :由于；因为;
翻译：8000米以上的冰盖会因为全球变暖而融化吗？
练习：因为信仰，他拒绝剪去头发。
He refused to cut his hair due to his beliefs.  

During this science trip, the researchers also measured (测量) the thickness of ice and snow at the summit with a high-precision radar (高精度雷达). Then, they collected ice and snow samples. They will examine the changing environments and ecosystems on the mountain, as well as study the effects of human activity on the area, Xinhua reported. 
summit [ˈsʌmɪt] ：n.  顶点; 高层会议; 最高阶层;
翻译：在这次科学之旅中，研究人员还用高精度雷达测量了山顶上的冰和雪的厚度。
练习：中午时分我们抵达峰顶。
We reached the summit at noon.
examine [ɪɡˈzæmɪn] ：v.  仔细检查; 检查身体; 审查; 考核;
翻译：他们将研究山上不断变化的环境和生态系统，同时研究人类活动对该地区的影响。
练习：老师将测验学生们的音乐知识。
The teacher will examine the students in music.

参考答案
1. 本题为细节理解题。由With heavy winds, low oxygen and -25 C temperatures, Qomolangma is one of the hardest mountains to climb可知，多种恶劣自然条件使得珠穆朗玛成为了世界上最难以攀爬的山峰之一，只有C选项为其中之一，故选C。

2. 本题为细节判断题。由本段可知Balcony Station由英美科学家建于2019年，坐落在海拔大约8430米的地方，中国的自动气象观测站取代它成为了世界上海拔最高的观测站，因此在此之前Balcony Station为最高气象站 ，所以正确答案为C。

3. 本题为细节信息题。由It has a satellite communication system that can transmit data every 12 minutes可知，它传送数据的周期为12分钟，因此正确答案为A选项。

4. 本题为主旨归纳题。由文意所给的实例可知观测站提供了各项有价值的研究数据，这些能够帮助科学家们解答问题，因此正确答案为C选项。
