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 (柳树) attacked in the woods by caterpillars (毛毛虫) changed the chemistry of its leaves and made them tasteless so 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 themselves taste also terrible, too.
Talking, 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 shy shouldn’t trees have ways of sending messages?(173 words) 51.From the passage, which kind of leaves don’t caterpillars eat?
A. leaves lying on the ground. B. leaves having an unpleasant taste. C. leaves bees don’t like. D.leaves having an unfamiliar shape. 52、The willow tree described in the passage protected itself by _________. A. growing more branches B. talking with birds and bees. C. changing its leaf chemistry D. shaking caterpillars off
53、According to the passage, the willow tree was able to talk with other trees by ___________. A. Waving its branches B. giving off a special smell
C.dropping its leaves D.changing the colour of its trunk 54、According to the passage, bees talk by _________.
A.making special movements B.touching one another C.smelling one another D.making unusual sounds 55、What does the author think about the idea that trees can talk? A.it is not true at all. B.only a few people believe it.
C The scientists made some mistakes D. It seems very reasonable.
