【题目】

When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a special smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be a warning. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds（VOCs）.

Scientists have found that all kinds of plants give out VOCs when being attacked. It’s a plant’s way of crying out. But is anyone listening? Obviously. Because we can watch the neighbors’ react.

Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes to attract different insects who are their natural enemies. Once the insects arrive, the tables are turned. The attacker who was lunching now becomes lunch.

In study after study, it appears that these chemical conversations help the neighbors. The damage is usually more serious on the first plant, but the neighbors stay safer because they heard the warning and knew what to do.

Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in fact, was talking to itself. Perhaps the neighbors just happened to hear the cry by accident and so wrong information was exchanged.

Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate than the world we can see and hear, our senses are weak. There’s a whole lot going on.
