As darkness fell, hundreds of people in the Swiss village left their houses. They were staring(凝视)1 at the mountain top in the distance. It was covered with 2一beautiful and dangerous.

    The huge mountain is called Matterhorn Mountain climbers had 3 the top, using the southern route. But no one had ever dared(敢)to try a winter climbing up the 4 side. But now one man was daring to try the 5 route. He was Walter Bonatti, a great mountain climber from Italy.

    For two days he had climbed. The village people had watched him anxiously(焦急地). Now they were waiting to see his signal(信号). If he planned to 6 the next day, he would light a green signal. A red light would mean that he was turning back.

    A tiny green light 7 high on the mountain side. Bonatti was not giving up! The people 8.

    The next day he continued his way upward. He was so lonely and so9! But he would not give up. Again that night he lit the 10light.

    In the morning, Bonatti 11. He couldn't see the top, but he knew he was 12 there. Though the climb was painful, he moved up.

    Bonatti had spent months 13 for the climb. Was the training enough? Did he have the strength and skill to climb to the top?

    He was finally at the top! News about his 14 was radioed to the world.

    The trip down the southern route was easy. He was warmly welcomed in the village. He had done the “15” and would be well remembered as a climber of all time.
