单选题 Why can some pyramids built thousands of years ago remain well preserved?
【正确答案】 C
【答案解析】[听力原文] 14-16
The oldest stone buildings in the world are the pyramids. Some of the pyramids still look much as they must have done when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modern buildings. Both the dry climate of Egypt and the very shape of the pyramids have contributed to the preservation of these old buildings, and months of pre-construction planning cannot be forgotten. The first thing taken into consideration by the Egyptians was to choose west side of the Nile; the side on which is the sunset. This was for religious reasons. It also had to stand well above the level of the river to protect against the regular floods. It could not be too far from the Nile, however, as the stones to build it needed to be carried in boats down the river to the nearest point, water transport was, of course, much easier than land transport. The builders also had to find a rock base, which was not likely to crack under the great weight of the pyramid. Finally, it had to be near the capital or better still, near the King's palace so that he could visit it easily and personally check the progress being made on the final resting place for his body.
