Can trees talk? Yes—but not in words. Scientists have reasons to believe that trees do communicate 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 the caterpillars got tired of the leaves and stopped eating them. The even more astonishing, the tree sent out a special vapor — a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn’t need to be always 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, 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 ways of sending messages?
【小题1】Why did Caterpillars stop eating the leaves of a willow tree? (No more than 15 words)
【小题2】According to the passage, how do bees communicate with each other? (No more than 5 words)
【小题3】What is the main idea of this passage? (No more than 5 words)Because the leaves of the willow tree tasted terrible.

(答案→)Because the leaves of the willow tree tasted terrible. 解析：文章讲述的是树和树之间，动物和动物之间也是群在沟通交流的。【小题1】Because the leaves of the willow tree tasted terrible. 根据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 the caterpillars got tired of the leaves and stopped eating them.可知【小题2】By dancing their signals/flying in certain patterns 根据Bees dance their signals, flying in certain patterns that tell other bees where to find nectar(花蜜) for honey.可知【小题3】Trees and animals can talk/communicate. 通过文章可知文章主要讲的是树和树之间，动物和动物之间也是群在沟通交流的。可以根据开头的问句得知。
