With 35 watchtowers over a stretch of only 5 ½ kilometers, the Simatai section of the Great Wall has probably the greatest number of watchtowers per kilometer than any other section of the Great Wall. Simatai Great Wall is divided into two subsections that lie on either side of a lake, Yuanyang Hu ("Mandarin Duck Lake"), which is fed by two springs, one hot and the other cold, with the result that the lake never freezes over even during the severest of winters. The subsection of the Simatai section that lies west of Mandarin Duck Lake snakes up a gently rounded mountain ridge. Here there are 20 watchtowers spread out at varying distances, in keeping with the dictates of the terrain and the need for supply depots/ added fortifications (which is the role played by the watchtowers).
To the east of the lake, the terrain changes character entirely, with a rugged mountain ridge that resembles the “razor” back of a wild boar. Here there are 15 watchtowers, most of them located on sheer precipices, and most of them situated at an altitude of above 1000 meters above sea level. The terrain to the east of the lake descends sharply, right down to the water's edge, with no shoreline to speak of.
Since both subsections of the Simatai section of the Great Wall descend from either side into the depression in which Mandarin Duck Lake is nestled, and since the snaking mountain ridges on either side of the lake are visible from the far end of the oblong lake, the macro view of the landscape, according to the vividly imaginative Chinese imagination, is one of two dragons leaping out of the lake, each in opposite directions.

答案

.全长5.4公里的司马台长城有35座敌楼,大概是长城中平均每公里拥有敌楼最多的部分.
.司马台长城被鸳鸯湖分成两部分,鸳鸯湖湖水由两股泉水汇合而成,湖水冷暖参半,致使湖水在严寒的冬天也从不结冰.
司马台长城西线,长城蜿蜒曲折地围绕着山脊.在这里在不同的距离分布了20个敌台,紧密的结合了地形,提供军库补给和防御敌人(这就是敌台的作用)
在司马台的东线上,地形完全改变了,粗狂崎岖的山脊像被刀削神斧头过,在这里有15座敌台,它们大部分坐落在陡峭的悬崖上,海拔多高于海平面1000米.值得一提的是这里的地形突然的下降,直至湖的边缘,没有一点湖岸.
从方形的湖边能看到司马台长城的两部分蜿蜒曲折地沿着鸳鸯湖下降,在中国人丰富的想象之下,巨大的风景犹如两条龙在湖面上向不同的方向腾空而起.
