Most young people 21 some form of 22    activity.  It may be walking, cycling,or swimming, or in winter, skating, or skiing. It may be a game of some kind—football, hockey, golf or tennis. It may be mountaineering. (登山运动) Those who have a 23 for climbing high and difficult mountains are often 24 with astonishment. Why are men and women willing to 25 cold and hardship, and to take 26 on high mountains? This astonishment is caused, probably, by the 27 between mountaineering and other forms of activity 28 which men 29 their leisure (空闲的) time. Mountaineering is a sport and not a game. There are no manmade rules, 30 there are for such games as golf and football. There are, 31 rules of a different kind which would be dangerous to ignore, but it is this freedom from manmade rules 32 makes mountaineering 33 to many people. Those who climb mountains are 34 to use their own methods. If we compare mountaineering and other more familiar sports we might think that one big difference is that mountaineering is not a “team game” .We should be mistaken in this. There are , it is true, no “matches” between “teams” of climbers but when climbers are on a rock face 35 by a rope 36 which their lives may depend, there is obviously teamwork. The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical 37. A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis 38 are in their early twenties. 39 it is not unusual 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 skills and less waste of effort, and they certainly 40 equal enjoyment. 小题1: A．please B．play C．get D．enjoy 小题2: A．physical B．mental C．joy D．pleasant 小题3: A．feeling B．thirst C．possession D．position 小题4: A．looked down B．looked out C．looked upon D．looked round 小题5: A．suffer B．observe C．enjoy D．stare at 小题6: A．danger B．pains C．risks D．efforts 小题7: A．difference B．distance C．similarity D．relationship 小题8: A．into B．at C．for D．to 小题9: A．draw B．spend C．devote D．spare 小题10: A．as B．and C．or D．so 小题11: A．sometimes B．however C．of course D．therefore 小题12: A．which B．that C．what D．whatever 小题13: A．satisfying B．tiresome C．terrifying D．attractive 小题14: A．urged B．forced C．limited D．free 小题15: A．fixed B．hung C．linked D．winded 小题16: A．at B．in C．over D．on 小题17: A．efforts B．spirits C．techniques D．qualities 小题18: A．athletes B．observers C．champions D．sportsmen 小题19: A．But B．Therefore C．So D．Thus 小题20: A．experience B．give C．receive D．want
