8 完形填空。 I have two friends who are eager for travel, There is a part of New York"s Adirondack Mountains that is called the High Peaks. It consists of 46 mountains with the height of over 4 000 feet. The Adirondack Mountain Club gives a small piece of land to anyone who 1 all the 46 mountains. My two friends decided to go for this 2 . It took them several years to accomplish it; it was hard to achieve. Many of the 46 mountains have 3 and well-used walkways to their tops. However, others are not marked at all. These mountains are really hard to climb 4 travelers have to bushwhack (在丛林中开道) them using a compass and a map. My 5 had climbed 45 of the mountains. They had one left that was the highest, requiring bushwhacking. They left their camp site early one 6 and walked to the foot of the mountains. When they reached the foot they found that they had 7 their compass and the map in the camp. Rather than returning to the camp, they decided to bushwhack without the compass and map. For nearly ten hours they walked uphill 8 heat, thick bushes and black flies. Finally, late in the afternoon they found themselves at the top of a mountain. They were exhausted but excited.
