Some people have power over plants. There is a saying in England that some people have “green fingers.” It means that they are very good 41 making plants grow. Others believe that if they talk to their plants 42 kind words and a soft voice, they will help them to grow better. But if they shout at them, the plants may stop growing. It’s rather difficult to prove 43 or not this is true. 44 , some studies have shown that music can affect plants. AnAmerican woman student 45 different kinds of music to plants. When she played classical music (Bach orBeethoven), she found that the plants grew towards and around the loud-speakers; but when she played pop music, the
plants grow in the opposite direction as if they were trying to escape from it. Plants apparently like soft music and not loud music, perhaps they also like the sound of soft voices.
