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] We can know from the passage the willow trees get protection by______.
选项
A、becoming thicker and thicker

D、shaking the insects off themselves
答案

解析
细节辨认题。根据文章首段第五句可知,柳树被毛虫侵袭之后就会改变树叶的化学成分,让毛虫厌恶树叶的味道。由此可知。柳树保护自己免受毛虫侵袭的方式就是改变树叶中的化学成分。
