Can trees talk?

人與人之間有著溝通與交流的方式，各種動物、鳥類也都用各種聲音、動作來傳遞信息，蜜蜂也通過跳舞來傳播信息。那么大自然中樹木有沒有自己交流的方式呢？

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 vapour — a signal causing its neighbours 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(密) for honey. So why shouldn’t trees have  ways of sending messages?

【答案與解析】樹同動物們一樣也可以用自己的方式交流。

1. A。判斷題。正因為毛毛蟲覺得柳樹葉可口，它們才吃柳樹葉的。

2. A。語義理解題。從第 1 段第 4 句話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 可以做出正確選擇。

3. D。語義理解題。從第 2 段倒數第 2 句話 …flying in certain patterns that tell other bees where to find nectar(花蜜) for honey 可以知道bees交流的方式。
