What do you know about the Mount Qomolangma? During May, most places in China are warm. But Mount Qomolangma is still cold and (cover) with snow. At this time, a group of Chinese climbers are climbing (high) mountain in the world. They are going to measure(测量)the height 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). the height can change as Earth's plats (板块) move. As technology improves, people want to get (many) exact numbers.
However, measuring its height is not easy. temperature there is -29℃, four degrees lower than that in Antarctica(南极). The snow there is 4—5 meters thick and strong winds blow all the time. Climbers have to carry scientific machines to the (world) rooftop (屋脊). They collect data(数据)on the top of the mountain.
To deal with the difficult conditions, team members started training in January. They have to sleep in their tents (keep) warm. To save fresh water, climbers seldom take a shower or wash faces. As for food, they have three dishes and soup for each meal. It is easy to keep meat fresh such a low temperature.
Though there are also some other (difficult) that we can not think of, the mountain is still worth measuring. An exact measurement can help to study the plate movement so that scientists can warn people the (come) of the earthquakes.
