user: Ques: Read the article and select the best answer. Article: Ed Viesturs grew up in Rockford, Illinois, where the tallest thing on the horizon was the water tower. But on Thursday, Viesturs became the only American to climb to the top of the world's 14 highest mountains. His last hike was up Mount Annapurna, in Asia's snowcapped Himalayas. At 26,545 feet, its peak is the 10th highest in the world. It is the mountain that inspired him to start climbing. "It tends to be the trickiest, the most dangerous," said Viesturs. "There's no simple way to climb it. There are threatening avalanches   and ice falls that protect the mountain." In high school, Viesturs read French climber Maurice Herzog's tale of climbing the icy Annapurna. Herzog's story was of frostbite   and difficulty and near-death experiences. Viesturs was right away. Viesturs got his start on Washington's Mount Rainier in 1977, guiding hikes in the summer. Fifteen years ago, he set out to walk up to the world's highest peaks. Finally, he's done. The pioneering climber talks about mountains as if they were living creatures that should be treated with respect. "You have to use all of your senses, all of your abilities to see if the mountain will let you climb it," said Viesturs. "If we have the patience and the respect, and if we're here at the right time, under the right circumstances, they allow us to go up, and allow us to come down." What's next for a man who can't stop climbing? "I'm going to hug my wife and kids and kind of kick back and enjoy the summer," says Viesturs. But for a man who's climbed the world's 14 tallest mountains, he will probably soon set off on yet another adventure. Question: What's the next probably plan of Viestures? Options: A: Stopping climbing and staying with his family. B: Climbing to the top of the world's 14 tallest mountains again. C: Climbing another one of the highest mountains. D: Writing down the experiences about his adventure.
Ans: C

Ques: Read the article and select the best answer. Article: A man walked down the trail on a cold, gray day. He was wearing heavy clothes and fur boots. But he still felt cold and uncomfortable. 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 snow-covered ice. It was a trail that would lead him straight to Henderson Creek and his friends. As he walked, he looked charily at 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 snow-covered 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... Question: After his feet sank into the water the man had to stop for a while in that   _  . Options: A: he had to get some food for physical strength B: he had to reevaluate the safety of the path C: it was too cold to go any further D: he had to dry his clothes and boots
Ans: D

Ques: Read the article and select the best answer. Article: There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do. In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly  determined, boys pattern their play after the activities of their fathers and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world. What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality  of toys with regard to their development in all parts of the world and their persistence to the present that is amazing. In Egypt, America, China, Japan and among the Arctic people, generally the same kinds of toys appeared. Differences depended on local customs and way of life because toys imitate their surrounding. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles. Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize(...) inventions for adult use. The progress from the wheel to the cart to the automobile is a direct line of ways up. The progress from a rattle  used by a baby in 3,000 BC to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the time and subject to the limitations of available materials. Question: The author uses the example of a rattle to show that  _  . Options: A: it often takes a long time to introduce new technology into toy-making B: even the simplest toys can reflect the progress of technology C: even a simple toy can mirror the artistic tastes of the time D: in toy-making there is a continuity in the use of materials
