Question

阅读下列短文 从所给的四个选项中 选出最佳答案。

    Can trees talk? Yes—but not in words. Scientists have　　 reason to believe that trees do communicate (互通信息)with each other. Not long ago researchers learned some surprising things. First a willow tree (柳树) attacked in　　 the woods by caterpillars (毛毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing the tree sent out a special vapours—a signal causing its neighbours to change the chemistry of their own leaves and make them less tasty.　　

    Communication of course doesn't need to be in words. We can talk to　　 each other by smiling raising our shoulders and moving our hands. We　　 know that birds and animals use a whole vocabulary of songs and movements. Bees dance their signals flying in certain patterns that tell other bees where to find nectar (花蜜) for honey.

　　     So why shouldn't trees have ways of sending messages?
