单选题
Most young people enjoy physical activities, walking, cycling, football, or mountaineering.
These who have a passion{{U}} (26) {{/U}}climbing high and difficult mountains are often{{U}} (27) {{/U}}with astonishment. Why are men and women{{U}} (28) {{/U}}to suffer cold and hardship, and to{{U}} (29) {{/U}}on high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activities{{U}} (30) {{/U}}which men give their leisure.

A mountain climber knows that he may have to fight with natural{{U}} (39) {{/U}}that are stronger and more powerful than man. His sport requires high mental and{{U}} (40) {{/U}}qualities.
A mountain climber{{U}} (41) {{/U}}to improve on skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions{{U}} (42) {{/U}}in their early twenties. But it is not{{U}} (43) {{/U}}for men of fifty or sixty to climb the highest mountains in the Alps. They may take more{{U}} (44) {{/U}}than younger men, but they probably climb with more skill and less{{U}} (45) {{/U}}of effort, and they certainly experience equal enjoyment.
