【英语时差8,16】震动更易捕蠕虫

（单词翻译）

You've never heard of worm grunting¹? Well,it's a practice of driving a wooden stake into the ground and vibrating it with a flat piece of iron. The vibrations² run through the soil and cause nearby earthworms to burrow³ up to the surface, where they can easily be collected. In fact there are many people in the southeastern United States who do this for a living. A researcher at Vanderbilt University demonstrated that the process of worm grunting produces vibrations that mimic⁴ the vibrations produced by moles⁶ while they are digging through soil. Moles are a subterranean⁷ predator⁸ of earthworms. In order to avoid becoming mole⁵ food, the earthworms flee to the top of the soil when they sense the vibrations of a mole that is digging nearby. You should try worm grunting. It might open up a whole new career for you.
