4 . Ask people to name the worlds tallest peak and anybody with general knowledge will name Mount Qomolangma. But quiz them on its exact________and many will be not sure.

In 1975, Chinese surveyors________that Mount Qomolangma was 8848. 13 metres high. As________was improved, satellites, photoelectricity, radar and gravity measurement technologies were________to get more exact figures. Of course, surveyors still had to carry________to what is the world's rooftop.

In 2005 , a Chinese team scaled Qomolangma and found that it was not as high as 8848. 13 metres, as they________the height to be 8844. 43 metres. Scaling Qomolangma is no________task. The average air temperature there is - 29℃ , even four degrees________than that in Antarctica. The snow there is 4—5 metres thick and hurricane-like________blow all the time.
