Scientists have found that plants can make sounds.
A scientist, Lily Hadany, and her team recorded(录制) tomato plants at different times. It showed that the plants made ultrasonic(超声波) sounds. People could only hear them with the help of a computer. They were noises like clicking(发出咔嗒声) sounds.
As scientists studied the sounds, they began to find some interesting facts. Plants made different sounds at different time. They seldom clicked when they had enough water, but when they needed water, they clicked more and more. Scientists also found that plants made sounds when they got hurt. When scientists cut off a leaf from the plants, the plants also clicked more. But this kind of clicking wasn't the same as when the plants needed water.
Some scientists designed a computer AI system to tell the different kinds of clicking sounds. It was able to find the difference between plants that needed water and plants with cuts. It means that one day we may be able to use these sounds to figure out when it is in difficult time, and what problem it is having. That could be very helpful to farmers.
The team's finding changes our ideas about plants. As Dr Hadany says, "Even in a quiet field, there are sounds made by plants, and those sounds carry information and may help us a lot. "
When my daughter was in primary school, she brought home four small twigs(细枝) from school to plant. None of them looked very strong and lively. But with hope for the future, I planted them somewhere in our backyard which could give them enough sunlight. Over the years, because of the poor soil(土壤), three of them died. Only one lived at last.
It grew crooked(不直的) and very slowly. In fact, it looked more like a fat bush than a tree. Later, I noticed that it was starting to die. The branches(树枝) were becoming bare. Only the top third of the tree was still green. I did my best to save it by feeding it a lot of fertilizer, but it didn't work.
Later one morning, I went out and looked at it again. I was thinking if it would be better to just cut it down. It would make the yard look cleaner. As I walked over to take a closer look at it, however, I noticed something moving within the leaves. It was a bird patiently building a nest in the topmost branches. I smiled when I looked at it. I thought maybe this old tree was still useful. It might not be healthy or pretty, but it was still giving a bird a home.
This tree let me know that all of our lives have a purpose. It doesn't matter if we are young and strong or old and sickly. Until our last breath, we have things to do, love to give, and joy to share. We can help to make this world a better and more beautiful place.
