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 American explorer named Paul Kosok suggested that the drawings are a chronicle (記錄) 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.
答案與解析：
46.F。空格後句子講到從高處看時這些藝術品的外觀。通過句首的轉折詞but可知，空格處應該填入“與地面上”觀察的反義詞，因此F(從地面上看)是符合上下文語義的選項。
47.D。空格前講道研究者得知這些線條已有1500年的歷史，但其存在的目的還不得而知。空格處應該進一步說明這種情況。因此，D選項(一個瑞士作家寫到Nazca lines被設計成一個UF0的著陸場所)正是對目的的一種猜測。空格後的轉折詞(however)表示對這種猜測的否定。因此D為最佳選項。
48.C。空格前講的是“一個美國人認為這是星球和行星的運動記錄”，符合上下文語義走向的是他把Nazca叫做“世界上最大的太空書籍”。因此C是最佳答案。
49.B。本段大意是“這些線條可能是因為宗教目的而設定的.”。B是最符合上下文語義走向的：最大的圖片是在特殊儀式上才用的。故B為正確選項。
50.E。最後一段講某些科學家對Nazca的推測。空格前講某些科學家的研究，空格處填入其他科學家的做法是比較符合上下文含義的。故E是正確答案。
