       Can trees talk? Yes,but not in words. Scientists have reasons to believe that trees can communicate with each other. Not long ago,researchers learned some surprising things. Some caterpillars (毛毛虫) attacked a willow tree (柳树) in the woods. The tree changed the chemistry of its leaves and the leaves tasted so terrible that the caterpillars stopped eating them. The even more surprising thing is that the tree sent out a special vapour (蒸气) 一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?

    31. From the passage we know that caterpillars       .

        A .like willow tree’s leaves

       B. enjoy eating fallen leaves

       C. can talk to other caterpillars

       D. can send out a special vapour

    32. Caterpillars will stop eating willow tree’s leaves which       .

       A. have a chemical change and become tasteless

       B. have a pleasant taste

       C. are being attacked

       D. are communicating

    33. What makes the writer more surprised is that       .

       A. caterpillars slop eating willow tree’s leaves

       B. the willow tree can send out a special vapour

       C. trees can talk to each other by their words

        D. birds and animals all use vocabularies

    34. According to the passage,bees communicate with each other by       .

       A. talking   B. making unusual sounds

       C. flying certain patterns   D. singing songs

    35. Which of the following is WRONG according to the passage?

       A. Scientists believe that trees can talk with each other.

       B. The special vapour sent out by a willow tree is a signal.

       C. Trees should have their own ways to send messages.

       D. The writer thinks everything must use words to communicate.
