Question

【題目】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(毛蟲) 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】本篇科普文章講述了柳樹通過發(fā)出一種特別的氣味來同鄰居進行交流。作者認為就像人類微笑，鳥兒唱歌，蜜蜂跳舞一樣，樹也有傳送信息的方式。

【1】with考查固定搭配�？茖W家們有理由相信樹木確實互相交流。communicate with…與……交流。

【2】learned考查謂語動詞。研究人員了解到了一些令人驚訝的東西。根據(jù)前面的Not long ago可知，要用一般過去時。

【3】attacked考查過去分詞作定語。被毛毛蟲攻擊的柳樹改變自己樹葉的化學成分，讓蟲子不再吃了。a willow tree ___3___(attack) in the woods by caterpillars(毛蟲) changed the chemistry of its leaves，本句中tree是主語。謂語動詞是changed，attacked …by caterpillars是過去分詞，修飾主語tree。Tree與attack是邏輯上的被動關(guān)系。樹是被攻擊。

【4】gradually考查副詞。柳樹改變了自己樹葉的化學成分，它們的味道變得非常糟糕，所以漸漸地（gradually）毛蟲厭倦了樹葉，不再吃它們。副詞修飾句子故用gradually。

【5】astonishing考查形容詞作狀語。句意：更令人驚訝的（astonishing）是，樹散發(fā)出一種特殊的氣味。有些形容詞在某些固定結(jié)構(gòu)中可用作獨立成分，起承上啟下的作用（也可視為一種狀語）。如：More important, he’s got a steady job. 更重要的是他得到了一個穩(wěn)定的工作。
