7 完形填空。 Lie Yu Kou (Lie Zi) was showing Bo Hun Wu Ren his archery(射箭) skill. He 1 the bow to its full extent, had a cup of water 2 on his elbow, and released the arrow. As soon as the first arrow flew off, a second one was wound up. The moment the second one was winged, a third was ready, and all of them lodged in the same place. During all this time, his 3 was as still as a statue. After his performance, Lie Zi asked Bo Hun Wu Ren: "What do you think of my archery skill?" Bo Hun Wu Ren laughed: "This is still only a(an) 4 shot, not quite the perfect shot yet. Let"s climb up the mountain and stand on the 5 overhanging the abyss(深渊). We"ll see if you can 6 an arrow." Wu Ren then led Lie Zi up to a place eight hundred feet above a deep valley. Wu Ren turned his 7 to the edge of the cliff, 8 moving his feet until he was standing with his heels extending over the edge, and 9 Lie Zi to join him. Lie Zi was so 10 that he threw himself down on the ground, sweating from head to toe. Bo Hun Wu Ren raised the bow and shot the arrows from his bow, with no 11 missed.
