Prfessr Hadany and her team set up micrphnes t recrd tmat plants under different situatins. The result shwed that the plants made ultrasnic sunds（超声波）. 1
As the scientists studied the sunds, they ntice the regularity（规律性）. Plants hardly clicked（发出咔哒声） when they had enugh water. 2
When scientists cut ff a stem frm the plants, the plants als clicked mre . 3 The result suggests that researchers may ne day be able t use a plant's sunds t find ut when it is having truble, and what truble it is having. That culd be very helpful t farmers.
The ther research has shwn that plants als make sunds t cmmunicate in sme ways. When small animals n the plant attack（攻击） a plant, it will give a warning t its neighbrs. 4 It's a useful way fr plants t prtect themselves.
Then here is a questin: Is anything listening t the plants? Dr. Hadany pint s ut that mice wh live n plants can hear the sunds. The clicks may tell them whether a plant has prblems. 5
