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?
From the passage, we know that bees communicate with each other by______.
选项 A、touching the partners’ bodies
B、making certain patterns of movements
C、using eye signals
D、making some strange sounds
答案B
解析 细节辨认题.文章的倒数第二句指明了蜜蜂的交流方式一通过某种形式的飞行来传递信息。据此可推断B)“做某种形式的活动”为正确答案。
