单选题
Most young people enjoy some form of physical
activity. It may be a game of some{{U}} {{U}} 1 {{/U}}
{{/U}}-football, hockey, golf, or tennis. It may be mountaineering. Those who have
a(n){{U}} {{U}} 2 {{/U}} {{/U}}for climbing mountains are often
{{U}} {{U}} 3 {{/U}} {{/U}}with astonishment. Why are men and
women willing to {{U}} {{U}} 4 {{/U}} {{/U}}cold and hardship,
and to take risks in high mountains? This astonishment is caused, {{U}}
{{U}} 5 {{/U}} {{/U}}, by the difference between mountaineering and
other forms of activity. Mountaineering is a sport and not a
game. There are no man-made rules, {{U}} {{U}} 6 {{/U}}
{{/U}}there are for such games as golf and football. There are, {{U}}
{{U}} 7 {{/U}} {{/U}}, rules of a different kind which it would be
dangerous to {{U}} {{U}} 8 {{/U}} {{/U}}, but it is this freedom
from man-made rules that makes mountaineering {{U}} {{U}} 9
{{/U}} {{/U}}to many people. Those who climb mountains are {{U}} {{U}}
10 {{/U}} {{/U}}to use their own methods. If we compare
mountaineering and other more {{U}} {{U}} 11 {{/U}}
{{/U}}sports, we might think that one big {{U}} {{U}} 12 {{/U}}
{{/U}}is that mountaineering is not a "team game". We should be mistaken
{{U}} {{U}} 13 {{/U}} {{/U}}this. There are, it is true, no
"matches" between "teams" of climbers, but when climbers are on a rock
face {{U}} {{U}} 14 {{/U}} {{/U}}by a rope on which their lives
may depend, there is {{U}} {{U}} 15 {{/U}}
{{/U}}teamwork. The mountain climber knows that he may have to
{{U}} {{U}} 16 {{/U}} {{/U}}forces that are stronger and more
powerful than man. His sport requires high mental and physical {{U}}
{{U}} 17 {{/U}} {{/U}}. A skier is probably past
his {{U}} {{U}} 18 {{/U}} {{/U}}by the age of thirty, and most
international tennis champions are in their early twenties. But it is not
{{U}} {{U}} 19 {{/U}} {{/U}}for men of fifty or sixty to climb
the highest mountains in the Alps. They may take more time than younger men, but
they probably climb with more skill and less {{U}} {{U}} 20
{{/U}} {{/U}}of effort, and they certainly experience equal enjoyment.
【答案解析】语义逻辑题，考查词义辨析。“登山运动的规则有异于其他运动，如果______这些规则，就会出危险”，会出危险通常是因为违反或忽视规则，B项符合句子逻辑。
在which引导的定语从句中，which指代先行词rules of different kind，因而填入的动词修饰的内容也应为rules of different kind，其他三项与其搭配句意不通，故排除。
【答案解析】语义逻辑题，考查词义辨析。转折词but表明五六十岁的登山运动员与年轻人不一样，他们攀登的技术可能更高，“力气的______可能更少”。技术高一点，那么耗费的力气就会少一点，所以本题选D项“耗费”。
