问题     If you fly over the Nazca Desert along the southern coast of Peru, you will see huge drawings in the sand; a monkey, a spider, flowers, triangles, rectangles, zigzags, spirals, even human forms with crowned heads. Also, straight lines can be seen spreading out from a circle, like spokes in a wheel. Some drawings are more than six hundred feet from end to end, longer than two football fields. Some continue for miles, up hills and down valleys. In all, the markings cover 250 square miles of desert.  Some drawings are so large that you can tell what they are only by looking at them from the air.   But no one knows how they got there, or why.

    We do know they were made about two thousand years ago by South American Indians called the Nazcas. The Nazca people lived in a green valley just below a huge stretch of desert called the pampas, meaning "flat place". The air around the pampas is hot and dry, and the pampas gets only about half an inch of rain each year. So the markings made long ago on its sandy, stony surface have not been worn away by the weather even after two thousand years.
    To find some clues about why the drawings were made, we can turn to history and anthropology. We know that Spain conquered Peru in 1532. The Spaniards destroyed much of the Peruvian way of life, except in remote regions of the Andes Mountains. Today, descendants of the Peruvian natives who survived live in villages along the mountainsides. Farmers there have to hike thousands of feet each day to reach their fields. On their way, many of them perform religious ceremonies. Those ceremonies offer clues to the meaning of the Nazca lines.

    When you look at the drawings from the ground, the lines look like pathways. Along the pathways are stone mounds, littered with scraps of broken pottery. The pathways resemble the mountain paths where today’ s farmers make their religious processions. The farmers leave offerings at stone mounds, which they call wa’ kas, meaning shrines. The offerings include pieces of pottery, seashells, coca leaves, and food.
    In these sacred ceremonies, farmers ask the mountain gods and animal spirits of the Andes to send them water. Since similar offerings are found on the lines and mounds of the pampas, it is likely that the ancient Nazcas had similar beliefs. Since the pampas is one of the driest deserts on earth, it makes sense that the Nazcas would worship gods to bring them water. Perhaps the drawings were meant to be viewed by the gods.
    Perhaps we will never know the real meaning of the Nazca lines. But we do know that even though the Nazcas had none of our modern technology and few of the comforts of our modern society, they did extraordinary things. They made pottery and cloth with so much detail and colour that it is believed to be some of the best ever made. They developed superior irrigation canals for watering their fields. Then, too, they left us those mysterious drawings in the sand, leaving us wondering still about the people who made them. [br] Why do the Nazca drawings still exist after two thousand years?

选项

答案 Because the air around the pampas is so hot and dry that the sandy, stony surface  have not been worn away by the weather even after two thousand years.

解析 题目问的是为什么纳斯卡画在两千年后仍然存在。文章第二段最后两句提到潘帕斯草原周围的空气又热又干,而潘帕斯草原每年的降雨量大约只有半英寸。因此,即使经过了两千年,很久以前在沙石表面留下的印记也没有被气候所侵蚀。所以这些画在两千年后依然存在。
