【创新运用】
阅读理解
Plants are rooted(扎根) in one place.They can't run away from danger or walk over the sunny side of the garden.So they have to develop some special ways to protect themselves and grow in the nature.
Some scientists found that plants can sense their surroundings(环境).You've all seen plants grow towards light which is called phototropism.Even if the top of them are cut off,the plants don't change the direction.They sense the light and tell the rest of the plants how to grow then.
Some plants “talk” with each other by using “airmail” to warn each other of danger.Researchers in England cut the leaves of cabbages.The cabbages then produce a tiny number of chemicals(化学物质) that protect themselves from some insects.Strangely,the cabbages which aren't cut nearby also begin to give off their own different chemicals.That means they seem to receive a warning from their cabbage neighbours.
Most amazingly,plants have a great system of communication that can connect nearly every plant in a forest by fungi(真菌).It connects the roots of different plants to each other.Scientists call the system the “wood wide web”,similar to the internet we use.Using the network,plants can communicate and share information and even food with each other.
Whatever the case,plants are stranger and more wonderful than we can imagine.
