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)。
The output from a successful ping can also be useful in helping to determine network latency, as it reports on the time taken to receive the echo reply.
成功的ping的输出还有助于判断网络延迟，因为它会报告收到回显回复花费的时间。
The echo process will consist of two primitive tasks — receiving a message via the receive activity and replying to the sender via a reply activity.
回送流程将包括两个基本任务—通过receive活动接收一条消息以及通过reply活动向发送方作出应答。
For the echo process, you need some steps to be taken in a certain sequence, so you add a sequence as the top-level activity activity and then populate it with a receive and reply later.
对于这个回送流程，您需要让有些步骤按照一定的顺序执行，所以，您添加一个sequence作为顶层活动，然后再将receive和reply植入sequence。
"In despair, he screamed his beloved's name - Yi-Pei - to the heavens," Chang writes. "Then, like an echo from far away, he heard a reply."
“绝望中，他仰天尖叫着爱人的名字——‘依培’，”张写道，“随后，象是从远方传来了回声一样，他听到了一声应答。”
