总之，就像我刚才讲的，通过分析这些回声，蝙蝠可以确定，比如说，洞穴里是否有需要避开的墙壁，以及它的距离有多远。

Anyway, as I were saying, by analyzing these echoes, the bat can determine, say, if there is wall in a cave that it needs to avoid, and how far away it is.

事实上，有一些品种的蝙蝠不使用回声定位，而是依靠视觉来导航，但对很多蝙蝠来说，它们的视觉太弱了，确实不能依靠。

Actually, there are some species of bats, the ones that don't use echolocation that do rely on their vision for navigation, but it is true that for many bats, their vision is too weak to count on.

靠近村子正中的地方，她的脚步的回声掺杂了一些其它的声音；她看见路边不远处有一个麦仓，就猜想那些声音是讲道人的声音了。
