　　The Mysteries of Nazca

　　In the desert of Peru, 300 kilometers from Lima, one of the most unusual artworks in the world has mystified (迷惑) people for decades. 46 But from high above, these marks are huge images of birds, fish, seashells, all beautifully carved into the earth.

　　The Nazca lines are so difficult to see from the ground that they weren't discovered until the 1930s, when pilots spotted them while flying over the area. In all, there are about 70 different human and animal figures on the plain, along with 900 triangles, circles, and lines.

　　Researchers have figured out that the lines are at least 1,500 years old, but their purpose is still a mystery.47 However, it would probably be very tricky to land a spaceship in the middle of pictures of dogs and monkeys.

　　In the 1940s, an America

n explorer named Paul Kosok suggested that the drawings are a chronicle (记录) of the movement of the stars and planets.48 Later, an astronomer tested his theory with a computer, but he couldn't find any relation between the lines and movements in space.

　　Another explanation is that the lines may have been made for religious reasons. British researcher Tony Morrison investigated the customs of people in the Andes Mountain and learned that they sometimes pray by the side of the road. It's possible that in the past, the lines of Nazca were created for a similar purpose.49 But the local people have never constructed anything this big.

　　Recently, two other scientists, David Johnson and Steve Mabee, have speculated that lines could have been related to water. Nazca is one of the driest places in the world and receives only 2cm of rain every year. While Johnson was searching for ancient water sources in the area, he noticed that some waterways built by ancient people were connected with the lines. Johnson believes that the Nazca lines are a giant map of the underground water in the area. 50

　　A. Scholars differ in interpreting the purpose of the designs.

　　B. The largest picture may have been the sites for special ceremonies.

　　C. He called Nazca "the largest astronomy book in the world".

　　D. A Swiss writer named Erich von Daniken wrote that the Nazca lines were designed as a landing place for UFOs.

　　E. Other scientists are now searching for evidence to prove this.

　　F. Seen from the ground, it looks like lines scratched into the earth.

　　答案解析

　　46.F。空格后句子讲到从高处看时这些艺术品的外观。通过句首的转折词but可知，空格处应该填入“与地面上”观察的反义词，因此F(从地面上看)是符合上下文语义的选项。

　　47.D。空格前讲道研究者得知这些线条已有1500年的历史，但其存在的目的还不得而知。空格处应该进一步说明这种情况。因此，D选项(一个瑞士作家写到Nazca lines被设计成一个UF0的着陆场所)正是对目的的一种猜测。空格后的转折词(however)表示对这种猜测的否定。因此D为最佳选项。

　　48.C。空格前讲的是“一个美国人认为这是星球和行星的运动记录”，符合上下文语义走向的是他把Nazca叫做“世界上最大的太空书籍”。因此C是最佳答案。

　　49.B。本段大意是“这些线条可能是因为宗教目的而设置的”。B是最符合上下文语义走向的：最大的图片是在特殊仪式上才用的。故B为正确选项。

　　50.E。最后一段讲某些科学家对Nazca的推测。空格前讲某些科学家的研究，空格处填入其他科学家的做法是比较符合上下文含义的。故E是正确答案。
