We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we will let others know soon. But do you know that a tree can talk and share news? It sounds strange, but it’s true that some trees can also communicate with each other. Of course, no tree moves lips and says words just as people do.
Willow trees (柳树) are the best-known of these trees. When insects (昆虫) begin eating a willow tree, the tree gives out a special smell at once. This smell tells the other willow trees that insects are coming near. All of them quickly make a chemical (化学物质) in their leaves. This chemical is bad for the insects. The insects do not like it and they fly away soon. In this way, the willow trees keep themselves away from the insect.
Next time when you take a walk near the trees, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees can “talk” to each other, too.
