Question

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(柳樹) attacked in the woods by caterpillars(毛毛蟲) 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?

2. 2.
   According to the passage, how do bees communicate with each other? (No more than 5 words)
3. 3.
   What is the main idea of this passage? (No more than 5 words)

Answer 1

1. Because the leaves of the willow tree tasted terrible
2. By dancing their signals/flying in certain patterns
3. Trees and animals can talk/communicate
文章講述的是樹和樹之間，動物和動物之間也是群在溝通交流的。
1.Because the leaves of the willow tree tasted terrible.  根據(jù)willow tree(柳樹) attacked in the woods by caterpillars(毛毛蟲) 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
2.By dancing their signals/flying in certain patterns 根據(jù)Bees dance their signals, flying in certain patterns that tell other bees where to find nectar(花蜜) for honey.可知
3.Trees and animals can talk/communicate. 通過文章可知文章主要講的是樹和樹之間，動物和動物之間也是群在溝通交流的�？梢愿鶕�(jù)開頭的問句得知。
