Question

【题目】Can trees talk? Yes, not in words. Scientists have reasons to believe that trees do communicate 【1】 each other.

Not long ago, researchers 【2】(learn) some surprising things. First a willow tree 【3】(attack) in the woods by caterpillars(毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves 【4】(gradual) and stopped eating them. Then even more 【5】(astonish), the tree sent out a special smell—a signal causing 【6】 neighbors to change the chemistry of their own leaves and make them less tasty.

Communication, of course, doesn’t need to be in words. We can talk to each other by smiling, raiding our shoulders and moving our hands. 【7】 we know is that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals. 【8】(fly) in certain patterns that tell other bees where 【9】 (find) nectar(花蜜) for honey. So why shouldn’t trees have 【10】(way) of sending messages?

【解析】本篇科普文章讲述了柳树通过发出一种特别的气味来同邻居进行交流。作者认为就像人类微笑，鸟儿唱歌，蜜蜂跳舞一样，树也有传送信息的方式。

【1】with考查固定搭配。科学家们有理由相信树木确实互相交流。communicate with…与……交流。

【2】learned考查谓语动词。研究人员了解到了一些令人惊讶的东西。根据前面的Not long ago可知，要用一般过去时。

【3】attacked考查过去分词作定语。被毛毛虫攻击的柳树改变自己树叶的化学成分，让虫子不再吃了。a willow tree ___3___(attack) in the woods by caterpillars(毛虫) changed the chemistry of its leaves，本句中tree是主语。谓语动词是changed，attacked …by caterpillars是过去分词，修饰主语tree。Tree与attack是逻辑上的被动关系。树是被攻击。

【4】gradually考查副词。柳树改变了自己树叶的化学成分，它们的味道变得非常糟糕，所以渐渐地（gradually）毛虫厌倦了树叶，不再吃它们。副词修饰句子故用gradually。

【5】astonishing考查形容词作状语。句意：更令人惊讶的（astonishing）是，树散发出一种特殊的气味。有些形容词在某些固定结构中可用作独立成分，起承上启下的作用（也可视为一种状语）。如：More important, he’s got a steady job. 更重要的是他得到了一个稳定的工作。
