Qomolangma is the world's highest mountain. You may have learned from your textbooks that its height is 8,848.86 metres. But not all sides are in agreement on this. Different researchers have given different results. In addition, the height of the mountain can change over time.
That's why a Chinese survey team with over 30 members set out to reach the peak of Qomolangma to remeasure its height on 6th May 2020. They were equipped(配备)with the latest technology.
It is not an easy task. The average air temperature on the mountain is —29℃, and powerful winds blow all the time. In such bad conditions, surveying drones(无人机)cannot work at the peak of the mountain. That's why it's still necessary to send human experts to the peak to get exact results.
But does a difference of a few metres really matter when it comes to a high mountain?
In fact, measuring the height of Qomolangma is about more than just getting one exact number. Mount Qomolangma is at the point where the Eurasian plate(欧亚板块)meets the Indian plate. It formed 38 million years ago as the two plates hit each other. Changes in the peak's height can show whether the two plates are heading toward or away from each other. This can help us understand the movement of the earth's crust(地壳).
The survey team will also get first-hand information about environmental conditions at the top of the mountain. This will help us understand the climate change.
()1. How many members were there in the Chinese survey team in 2020?
A. Over eighty. B. Over sixty. C. Over forty. D. Over thirty.
()2. What challenge did the Chinese survey team face?
A. A lack of water. B. Dangerous animals.
C. Bad weather conditions. D. The movement of the earth's crust.
()3. What is the main idea of the last two paragraphs?
A. Why measuring the height of Qomolangma is important.
B. What the changes in the height of Qomolangma's peak can tell us.
C. How Qomolangma became the highest mountain.
D. How plate movements affected the height of Qomolangma.

珠穆朗玛峰是世界上最高的山。你可能从课本上知道它的高度是8848.86米。但并非所有各方都同意这一点。不同的研究人员给出了不同的结果。此外，这座山的高度会随着时间而变化。
这就是为什么一个由30多名成员组成的中国考察队于2020年5月6日出发前往珠穆朗玛峰重新测量其高度的原因。他们配备了最新的技术。
这不是一件容易的事。山上的平均气温是-29℃，而且一直刮着大风。在这样恶劣的条件下，勘测无人机无法在山顶工作。这就是为什么仍然有必要派遣人类专家到顶峰以获得确切的结果。
但是对于一座高山来说，几米的差距真的重要吗？
事实上，测量珠穆朗玛峰的高度不仅仅是得到一个精确的数字。珠穆朗玛峰位于欧亚板块和印度板块的交汇处。它形成于3800万年前，两个板块相互碰撞。峰顶高度的变化可以显示两个板块是朝向对方还是远离对方。这可以帮助我们了解地壳的运动。
考察队还将获得有关山顶环境状况的第一手资料。这将有助于我们了解气候变化。
