三、完形填空
During May, most places in China are warm. But Mount Qomolangma is still  1  and covered with snow. At this time, a group of Chinese climbers are climbing the highest mountain in the world. They are going to measure(测量) the  2  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 plats (板块) move. As technology  3 , people want to get more exact numbers.
However, measuring its height is not easy. The temperature there is -29 ℃, four degrees lower than that in Antarctica (南极). The snow there is 4 to 5 meters  4  and strong winds blow all the time. Climbers have to carry scientific instruments to the world's rooftop (屋脊). They collect data (数据) on the  5  of the mountain. After that scientists study the data and calculate (计算) the height of the mountain.
To deal with the  6  conditions, team members started training in January. They have to sleep in their tents to keep warm. To  7  fresh water, climbers seldom (很少) 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 in such a  8  temperature.
Though there are also some other  9  that we can't think of, the mountain is still worth (值得) measuring. An exact measurement can help to study the plate movement  10  scientists can warn (警告) people the coming of the earthquakes.
