The shots echo through a forest of twisted holly trees, zigzagging up through the ravines to the granite peaks, as if searching for a reply. But there is no response, only the wind.
枪声枝桠环绕的冬青林中回荡，飘过山谷，盘旋在花岗岩的上空，好像在寻求一个答复，但他听到的只有风的呼啸。
If no echo reply is received, then one or more of the conditions described above hasn't been met and the ping fails (see Listing 2).
如果没有收到回显回复，就说明不满足上述一个或多个条件，ping失败了(见清单2)。
