中国再次测量珠峰“身高”
During May, most places in China are warm. But Mount Qomolangma is still cold and covered with snow. At this time, 35 Chinese climbers are climbing the world’s tallest mountain. They are going to measure (测量) the height (高度) of the mountain.
In fact, China already measured the height of the mountain in 1975 (8,848.13 meters) and 2005 (8,844.43 meters). But the height can change as Earth’s plates (板块) move. As technology improves, people want to get more exact figures (数字).

1. The climbing team takes their instruments to the top of the mountain.
2. They collect (收集) data (数据) there.
3. Scientists study the data and calculate (计算) the height of the mountain.
How do climbers live?
Where to sleep: four team members sleep in a tent (帐篷).
What to eat: three dishes and soup for each meal. Temperatures are low on the mountain, so it’s easy to keep meat fresh.
