Plant lovers believe that talking to plants helps them grow. Scientists havediscovered there could be some truth to it. Researchers have discovered that plants emit1 sounds when they are stressed. The noises are similar to a human cry orscream. The scientists believe the sounds are specific2 enough for us to be able tointerpret3 them and to attend to their needs. Unfortunately， plant sounds are at toohigh a frequency4 for the human ear to pick up.

Each plant and each type of stress is associated with a specific sound. Whilethe human ear cannot pick them up， the sounds emitted by plants can be heard bybats， mice， and insects. Interpreting these sounds could help us understand whencrops are dehydrated5. Farmers could water their crops more efficiently， and thussave water.

植物爱好者相信与植物交谈有助于它们的生长。科学家们发现，这可能有一定的道理。研究人员发现，植物在有压力时会发出声音。这种声音类似于人类的哭喊或尖叫。科学家们相信这些声音足够独特，我们能够解读它们并关注它们的需求。不幸的是，植物的声音频率太高，人耳无法捕捉。

每种植物和每种类型的压力都与一种特定的声音有关。虽然人耳听不到，但蝙蝠、老鼠和昆虫都能听到植物发出的声音。解读这些声音可以帮助我们了解作物何时脱水了。农民可以更有效地浇灌作物，从而节约用水。
