The man was on his way to a camp near Henderson Creek. His friends were already there. He expected to reach Henderson Creek by six o’clock that evening. It would be dark by then. His friends would have a fire and hot food ready for him. A dog walked behind the man. It was a big gray animal, half dog and half wolf. The dog did not like the extreme cold. It knew the weather was too cold to travel. The man continued to walk down the trail. He came to a frozen stream called Indian Creek. He began to walk on the snowcovered ice. It was a trail that would lead him straight to Henderson Creek and his friends. As he walked, he lookedcharilyat the ice in front of him. Once, he stopped suddenly, and then walked around a part of the frozen stream. He saw that an underground spring flowed under the ice at that spot. It made the ice thin. If he stepped there, he might break through the ice into a pool of water. To get his boots wet in such cold weather might kill him. His feet would turn to ice quickly. He could freeze to death. At about twelve o’clock, the man decided to stop to eat his lunch. He took off the glove on his right hand, opened his jacket and shirt, and pulled out his bread and meat. This took less than twenty seconds. Yet, his fingers began to freeze. He hit his hand against his leg several times until he felt a sharp pain. Then he quickly put his glove on his hand. He made a fire, beginning with small pieces of wood and adding larger ones. He sat on a snowcovered log and ate his lunch. He enjoyed the warm fire for a few minutes. Then he stood up and started walking on the frozen stream again. A half hour later, at a place where the snow seemed very solid, the ice broke. The man’s feet sank into the water. It was not deep, but his legs got wet to the knees. The man was angry. The accident would delay his arrival at the camp. He would have to build a fire now to dry his clothes and boots. He walked over to some small trees. They were covered with snow. In their branches were pieces of dry grass and wood left by flood waters earlier in the year. He put several large pieces of wood on the snow, under one of the trees. On top of the wood, he put some grass and dry branches. He pulled off his gloves, took out his matches, and lighted the fire. He fed the young flame with more wood. As the fire grew stronger, he gave it larger pieces of wood. He worked slowly and carefully. At sixty degrees below zero, a man with wet feet must not fail in his first attempt to build a fire. Fortunately, his fire was beginning to burn more strongly. He sat under the tree and thought of the old men in Fairbanks. The old men had told him that no man should travel alone in the Yukon when the temperature is sixty degrees below zero. Yet here he was. He had had an accident. He was alone. And he had saved himself. He had built a fire. Those old men were weak, he thought. A real man could travel alone. If a man stayed calm, he would be all right. 21． The man made his way to Henderson Creek to . an unfettable trip with his friends as planned the hard life there in person the first person to travel alone in the Yukon 22． Why did the man choose to walk on a trail with snowcovered ice? it was the shortest route. the scenery around was wonderful. it was a path advised by his friends. it was the only way to his destination. 23． After his feet sank into the water the man had to stop for a while in that . had to get some food for physical strength had to reevaluate the safety of the path was too cold to go any further had to dry his clothes and boots can we infer from the last paragraph? a fire in such an extreme condition was not as difficult as expected. fire successfully guaranteed the man’s safety to his destination at last. man was proud of his ability to survive in such an extreme condition. man’s experience proved that the old men in Fairbanks were reliable. B New Zealand will create one of the largest marine protected areas in the world, spanning an area of 620,000 sq km. The Kermadec Ocean Sanctuary (保護(hù)區(qū) ) will be one of the world’s most significant fully protected ecosystems, the prime minister of New Zealand, John Key, told the UN General Assembly in New York. The sanctuary is in the South Pacific Ocean, about 1,000 km northeast of New Zealand, and expands a marine reserve that surrounds some small islands. The area is considered important in terms of biodiversity, featuring nearly 35 species of whales and dolphins, 150 types of fish and three of the world’s seven sea turtle species. It is also geologically significant, including the world’s longest chain of underwater volcanoes and the second deepest ocean trench, into 10 km underwater — deeper than Mount Everest’s height. The scale of the sanctuary will dwarf (矮化 ) any previous New Zealand’s protected area, spanning twice the size of the country’s mainland. It will cover 15% of New Zealand’s economic zone. Commercial and recreational fishing will be pletely banned, as will oil, gas and mineral prospecting (勘探 ), exploration and mining. Key’s government aims to pass legislation establishing the sanctuary next year. The sanctuary is a worldclass, unspoiled marine environment and New Zealand is proud to protect it for future generations,Key said.New Zealanders value our coasts and oceans, which are an important part of our culture, economy and environment and we are mitted to managing them sustainably. Creating protected areas will support not only our own fisherie
