Questions 6 to 10 are based on the same passage or dialog. For any tourist visiting Egypt, there are two things that everyone must see. The first is the 137-meter-high Great Pyramid of Giza (吉萨大金字塔), the largest of all the pyramids in Egypt. The second is the Great Sphinx of Giza (吉萨大狮身人面像), a sculpture with the body of lion and the head of a man, which stands 20 meters tall and 73 meters long.
The origin of the Great Sphinx of Giza goes back 5,000 years. Although many sphinx sculptures have been found over the years, researchers believe that the Great Sphinx which guards the pyramids in Giza was actually the first one to be made (around 2600-2500 B.C.). The head of the Sphinx represents the king of Egypt at that time. About 2,000 years later, around 570 B.C., sand had covered all but the head of the Great Sphinx. The people living in the area had forgotten the history of the statue, so they imagined that the head represented the sun god and began to worship it. For hundreds of years, the Sphinx attracted people both as a religious monument and as a work of art. But eventually, the desert sand once again covered the Sphinx, leaving only the head visible. It was not until the 1800s that archaeologists (考古学家) began clearing the sand from the statue and began researching the long history of the Sphinx. At last, in the 1920s, all of the sand was finally cleared away and restoration work, which continues to this day, was begun.
