The Secret Language of Plants
Talking plants have long been a thing of myths and legends①.Many cultures have stories of talking trees [1]that give advice as well as warnings② to people. Alexander the Great and Marco Polo were said to have visited such a tree in India.And in some modern stories, such as the film Avatar, trees can communicate with animals and people③.
[2]With us long believing that talking plants are fantasy, new research has revealed something amazing④: it appears that plants can communicate after all⑤.
【释疑难】 [1]that引导定语从句,修饰先行词talking trees。
【赏靓点】 [2]句使用了“with+宾语+宾语补足语(doing)”的复合结构作状语,简洁地概括了人们长久以来的既定观念。冒号后的内容揭示了新的科学发现,与前半句形成鲜明对比,引出文章主题。
[3]It has been known for some time that plants use chemicals to communicate with each other.This happens when a plant, say a bean plant, gets attacked by⑥ insects.The plant releases tiny amounts of⑦ chemicals from the leaves that are being eaten.[4]This is like a warning, or a call for help: “I’m being attacked!” When another bean plant detects the chemicals⑧ from its injured neighbour, it starts to release its own, different chemicals.Some of these chemicals drive insects away⑨.Others attract insects — the wasps! The wasps kill the insects that are eating the bean plants.Scientists hope to learn more about this plant warning system, [5]so that we can use it to grow crops without pesticides.
More surprisingly, plants also use sound to communicate.People can’t hear these sounds, but plants are making them.Some plants make noises⑩ with their roots.Corn and chilli plants do this.They also “listen” to the noises from other plants.A chilli plant can tell if a neighbouring plant is helpful, or unfriendly.Some trees make clicking noises when there is not enough water, [6]indicating drought is arriving.
【释疑难】 [3]It作形式主语,真正的主语是that引导的从句。
[5]so that引导目的状语从句,意为“以便,为了”。
[6]indicating ...为动词-ing形式作伴随状语。
【赏靓点】 [4]句运用了明喻和拟人的修辞手法,将植物释放化学物质这一生物反应比作人类发出的“警告”或“求救信号”,并直接引用了拟人化的台词,使枯燥的科学现象变得生动有趣,通俗易懂。
Most surprisingly of all, plants have an amazing system of communication⑪ [7]that can link nearly every plant in a forest.Scientists call this system the “wood wide web”.It is in some ways similar to the Internet we use.[8]While the Internet is a worldwide network of computers⑫ linked by cables and satellites, the wood wide web is linked underground by fungi.This fungal network links the roots of different plants to each other.Using the wood wide web, plants can share information⑬ and even food with each other.For example, some pine trees can send food to⑭ smaller pine trees to help them grow.But just like our own Internet, the wood wide web has its own version of “cybercrime”.Plants can steal food from each other, or spread poisons to attack other plants.Perhaps one day scientists will learn [9]how to create a “firewall” to help prevent these attacks⑮ within the wood wide web.
Scientists are learning more every day about the secret ways [10]in which plants talk to each other.Who knows? Maybe one day we will know enough about plant communication to be able to “talk” with them ourselves.
【释疑难】 [7]that引导定语从句,修饰先行词communication。
[8]linked by ...为过去分词短语作后置定语,修饰名词computers。
[9]“疑问词+动词不定式”结构作learn的宾语。
[10]in which引导定语从句,修饰先行词ways。
【赏靓点】 [8]句作者将人类的互联网(由电缆和卫星连接)与植物的“万维网”(由地下真菌连接)进行类比,突出了两者在结构上的相似性,解释了“wood wide web”这一概念的由来。

赏析:firewall使用了隐喻。防火墙本指电脑网络的安全系统,这里用来指代未来可能研发出的保护植物免受真菌网络攻击的科学手段,用词新颖且贴切。
参考译文
植物密语
会说话的植物一直是神话传说中的一大元素。在许多种文化中流传下来的故事里,会说话的树给予人们忠告和警示。据说亚历山大大帝和马可•波罗曾在印度见过一棵会说话的树。在一些现代故事——例如电影《阿凡达》中,树可以与人类和动物沟通交流。
我们一直认为会说话的植物只存在于幻想之中,但新研究有了令人惊奇的发现:植物间似乎确实可以交流。
人们早就知道植物可以利用化学物质进行交流。当一株植物——比如豆科植物——被昆虫袭击时,就会发生这种情况。正遭受啃食的叶子会释放出微量的化学物质,这像是警示,抑或求救:“我被攻击了!”当另一株豆类植物察觉到附近受伤同伴释放的化学物质时,它自身便开始释放不同的化学物质,其中一些能驱赶昆虫,而另一些则会吸引另一种昆虫——黄蜂!黄蜂会杀死那些啃食豆类植物的昆虫。科学家们希望能进一步了解这种植物警报系统,从而将其应用于不用使用农药的农作物的种植。
更不可思议的是,植物也能用声音交流。虽然人类听不到,但植物确实正在发出声音。有些植物通过根部发出声响,比如玉米和辣椒。它们还能“听见”其他植物发出的声响。由此,辣椒可以知道自己附近的植物是敌是友。还有些树木在水分不足时会发出咔嗒声,以示干旱就要来了。
最令人惊奇的是,植物拥有一套神奇的信息交流系统,几乎可以连接起森林中所有的植物。科学家们称之为“植物万维网”。在某种程度上,它很像人类使用的互联网。互联网是通过电缆和卫星连接的全球计算机网络,而植物万维网则是在地下通过真菌连接而成的。这个真菌网络将不同植物的根彼此连接,通过它,植物
可以互相分享信息甚至是食物。比如,某些松树会通过真菌网络向松树幼苗输送养分,帮助它们生长。但是,像互联网一样,植物万维网也会发生“网络犯罪”。植物会偷取同伴的养分,或散播有毒物质攻击其他植物。也许未来某一天,科学家会研究出建造“防火墙”的方法来阻止植物万维网中的这些攻击。
科学家们每天都在增进对植物间相互沟通的秘密方式的了解。谁知道呢?说不定哪一天,我们就能足够了解植物沟通的知识,从而亲自和植物“聊天”了。
