①Scientists found that plants can make sounds.
②A scientist Lily Hadany and her team recorded(录制)tomato plants at different times. It showed that the plants made ultrasound(超声波). Humans could only hear them with the help of a computer.
③As the scientists studied the sounds, they began to find some interesting facts. Plants made different sounds at different times. They hardly made sounds when they had enough water, but as the earth got drier, they made more sounds. Scientists also found that plants made sounds when they got hurt. When scientists cut a part of stem from the plants, the plants also made sounds. But the sounds weren't the same as when the plants needed water.
④Some scientists trained a computer AI system to identify(识别) the different kinds of sounds. It could find the difference between plants that needed water and plants with cuts. It means that one day we may use these sounds to find out what problem it is having. That could be very helpful to farmers.
