问题     Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars (毛虫) changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special smell—a signal causing its neighbours to change the chemistry of their own leaves and make them less tasty.
    Communication, of course, does not need to be in words. We can talk to each other by smiling, shrugging our shoulders or making gestures. We know that birds and animals use a whole vocabulary of songs, sounds 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 their own ways of sending message? [br] Which of the following is mentioned as a way of human being’s communication?
选项 A、Flying in certain patterns.
B、Smiling.
C、Sending out a special smell.
D、Singing songs.
答案 B
