第45至48題爲題組From 1986 on, some of the world's most daring runners have gathered in the desert of Morocco every year to take part in one of the most difficult races in the world. The Marathon of the Sands, as it is called, covers over 125 miles of desert and mountain wilderness. The runners, paying roughly $5000 for their participation, are supposed to complete the course in fewer than seven days, running with all their personal belongings and food in their backpack.The Marathon of the Sands was founded in 1986, meant to give the runners an unforgettable adventure. For most of the runners, the challenge of the race is indeed the main reason for coming. On the first day，for example, they run fifteen miles across a desert of sand, rocks, and thorny bushes. Few runners finish the day without blistered and raw feet. When they arrive at the campsite for the night, they are completely exhausted. The second day，the runners are up at 6:00 am. Within a few hours，it is 100 degrees F, but the runners must cover eighteen miles that day. On the third day, the runners must climb giant sand dunes. Dust and sand mix with the runners' sweat and soon their faces are caked with mud. After fifteen miles of these conditions, the runners finally reach their next camp.The race continues like this for four more days. The fourth and fifth days are the worst. On the fourth day, the runners pass through a level stretch and a beautiful, tree-filled oasis, but then, on this and on the next day，they cross more than twenty-one miles of rocks and sand dunes. The temperature soars to 125 degrees F, and many runners cannot make it. Helicopters rush fallen runners to medical help. Runners who make it to the end of the fifth day know the worst is over.On the sixth day, heat and rocks punish the racers terribly. The desert wind picks up and, as the heat is thrust against them with great force，they grow more and more exhausted. The seventh day is the last, with only twelve miles to be covered. The dusty, tired, blistered runners set out at daybreak. Near the finish line, children race along with the runners, for everybody has caught the excitement The ones who have run the whole marathon know they have accomplished what most people could not even dream of. "During the hard moments," says one contestant who has raced here twice, "I'd think, 'Why am I here?' Then I'd realize I was there to find my limits."
