二、閱讀理解

• 5．Do plants listen to music？How can a plant possibly respond to music？Well，plants breathe through their many mouths，which are also known as stomata and it has been discovered that plant stomata respond to music!
     A few years ago，scientists at the University of California，San Diego discovered what controls a plant's stomata.The two cells that form the stoma consist of specialized cells adjusted to the resonant（共鳴的）frequency of calcium（鈣）．When exposed to this frequency the stomata close.However，if the frequency isn't exactly right the cells will open again within an hour.This happens even if the concentration of calcium is high enough that the stomata would normally close.
     When specific music or bird songs cause the plant to vibrate（顫動(dòng)），but not at the exact frequency for calcium resonance，the stomata will open after a misjudgment of time，even though the plant would keep them closed under normal circumstances.
     Testing has shown that a leaf fertilizer（肥料）applied to the plant will have more effect on the development and growth of the plant if its stomata are wide open.This is quite logical，because plants absorb the leaf fertilizer through their stomata.Combinations of frequency and leaf fertilizer are available for many different crops.However，if the stomata are forced to remain open，the plant won't be able to control the amount of water lost and so it risks dehydration（脫水）．As a result，exposing plants to music for over 3 hours a day could endanger their health.There could also be bad effects on plants if the volume or frequency is too high.
     It isn't exactly clear how music influences the development and growth of plants，but more and more is being discovered about resonance physics and we're closer than ever to solid scientific proof and theories in this area.Maybe，in twenty years' time people will laugh if you say plants don't have ears!
