查询词典 circular arc

The placer gold under the lake has high purity,so we called it Golden Lake.the area of the Golden lake is about 136 square kilometers among which the water area is about 26 square kilometers.it's 62 kilometers long,so we also called it "vast Golden lake".the shape of the lake is circular arc,it looks like a crescent.so people feel it is not very big.but at the lower reaches of lake ,it's 2 kilometers wide 5 kilometers long, so-called "ten mile slack water".and we will go there later.

这个湖底下沙金的含量非常高，因为湖底有黄金而取名为大金湖。大金湖的面积有136平方公里，其中水域面积有26平方公里。全长62公里，所以今天我们游览的金湖又有"百里金湖"之称。金湖整个形状呈一个圆弧形，看起来像一轮新月。所以大家觉得这个大金湖看起来不是很大。湖面最宽处是在下游，东西宽2公里，南北长5公里，号称"十里平湖"。呆会儿我们就会到那转一转。
