12、 Yulei began to melt as the weather warmed.The simplest fix was to build a dam, but this would have ruined the Minjiang River.

19、ack, 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 particular smell that neighboring plants can get.

20、lants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.Scientists have found that all kinds of plants give out VOCs when being attacked.Its a plant，s way of crying out. But is anyone listening? Apparently. Because we can watch the neighbors react.Som

21、e plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.In study after study, it

22、 appears that these chemical conversations help the neighbors. The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.Does this mean that plants talk to each other? Scientists don，t know. Maybe the fi
