外刊例句
Many bats use a system similar to sonar to navigate in the dark. They send out high frequency sound, sometimes as clicks, and get information about their surroundings by the timing and quality of the sound that bounces back. And just as turning up the light in a darkened room helps to illuminate the objects there, bats are known to turn up the intensity of their clicks when they have trouble detecting a target.
许多蝙蝠使用类似于声纳的系统在黑暗中飞行。它们会发出高频率声音,有时像“咔哒声”,并利用声音返回的时间和质量来获取周围环境的信息。就像在黑暗房间里开灯有助于照亮物体一样,人们了解到蝙蝠在探测目标遇到困难时,也会提高“咔哒声”的强度。
