"He is not an ordinary child. I have seen abilities in him. That's why I have appointed special teachers for him," Safi's father, Abdul Rehman Khan, said, "I want him to become a special leader. I'm very proud... For his abilities, for his intelligence."

　　　Abdul's description may seem exaggerated (夸张的）- he is Hammad's father after all - but the boy is indeed capable beyond his years. How many 11-year-old children do you know that can command the attention of thousands of adults while speaking on serious topics like success, life challenges or responsibility? Hammad can, and he does it with ease, relying on his great charm, practiced hand gestures and a confidence that attracts his audiences greatly.

　　　"A few months ago I was really disappointed with life...I was thinking about suicide, because there are no jobs and no success in life," a student said, "Then I saw a movie of Hammad Safi. I thought if an 11-year-old child can do anything, why can't I?"

　　　That is what makes Safi so special, his power to get his message across and inspire people much older than him.

　　　Many in Pakistan are astonished by Hammad's self-confidence and his ability to lecture on important subjects, but there are also those who believe that this role is depriving the boy of his childhood.

　　　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 particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants 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 .It's a plant's way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.

　　　Some 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 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 first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to "overhear" the cry. So information was exchanged, but it wasn't a true, intentional back and forth. Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. There's a whole lot going on.
