The Secret Language of Plants
Talking plants have long been a thing of myths and legends. Many cultures have stories of talking trees that give advice as well as warnings 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 people.

会说话的植物长久以来都是神话和传说里的事情。许多文化里都有会说话的树给人们警告和建议的故事。据说，亚历山大大帝和马可·波罗曾在印度见过这样一棵树。而且在一些现代故事中，像电影《阿凡达》，树木可以与动物和人交流。
Communicate with sb. 和某人交流
as well as 和，也

With us long believing that talking plants are fantasy， new research has revealed something amazing: it appears that plants can communicate after all．
我们一直认为会说话的植物只存在于幻想之中，但新的研究有了惊人的发现：植物间似乎确实可以交流。
reveal v. 揭露，表明，展示，显示
after all 毕竟，终究

With the College Entrance Examination drawing near
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 by insects. The plant releases tiny amounts of chemicals from the leaves that are being eaten. This is like a warning, or a call for help: “I'm being attacked！” When another bean plant detects the chemicals from its injured neighbour, it starts to release its own, different chemicals.
人们知道植物使用化学物质相互交流已经有一段时间了。当某种植物(比如豆类植物)受到昆虫侵害的时候就会这样做。(受侵害的)植株从正被啃食的叶子中释放出微量的化学物质，就像是发出警告或者呼救：“我被攻击了！”另一株豆类植物察觉到附近受伤植株释放出的化学物质时，它便开始释放自身不同的化学物质。
release v. 释放，发行，上映
detect v. 查明，检测出，侦察
tiny mounts of 微量的
Some of these chemicals drive insects away. 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, so that we can use it to grow crops without pesticides.
其中一些化学物质把昆虫驱走，另一些则会吸引昆虫——黄蜂！黄蜂会杀死正啃食豆类植株的昆虫。科学家希望能进一步了解这种植物警报系统，这样我们就可以利用其种植农作物，而不使用农药。
drive...away　 把……赶走
More surprisingly， plants also use sound to communicate. People can't hear these sounds, but plants are making them. Some plants make noises with their roots. Corn and chili plants do this. They also “listen” to the noises from other plants. A chilli plant can tell if a neighboring plant is helpful, or unfriendly. Some trees make clicking noises 1.when there is not enough water, indicating drought is arriving．
更令人惊讶的是，植物也会用声音交流。虽然人类无法听到，但是植物确实在发出声音。有些植物用根部发出响声，玉米和辣椒就是如此。它们还会“倾听”其他植物发出的声音。辣椒可以分辨出邻近的植物是敌是友。一些树在没有足够的水分时，会发出咔嗒声以示干旱即将来临。
indicate v.表明，指示
此处when引导时间状语从句，意为“当……时”；indicating...arriving是现在分词短语作伴随状语。
Most surprisingly of all, plants have an amazing system of communication 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. While the Internet is a worldwide network of computers 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.
最令人惊讶的是，植物之间有一个惊人的交流系统，该交流系统可以把森林里几乎每一株植物联系起来。科学家称该系统为“植物万维网”。它在某种程度上与我们使用的互联网相似。互联网是由电缆和卫星连接起来的全球计算机网络，而植物万维网是由真菌在地下连接而成的。这个真菌网络将不同植物的根系相互连接了起来。
link v./n. 联系
in some ways 在某种程度上
be similar to 与……相似
Using the wood wide web, plants can share information and even food with each other. For example, some pine trees can send food to 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 how to create a “firewall” to help prevent these attacks within the wood wide web.
通过植物万维网，植物可以相互分享信息甚至食物。例如，一些松树能够给松树幼苗输送养分，帮助它们生长。不过就像我们的互联网一样，植物万维网也有自己版本的“网络犯罪”。植物间会互相窃取食物，或者传播毒素以攻击其他植物。也许有一天，科学家将学会如何建造“防火墙”来帮助阻止植物万维网内部的攻击。
share sth. With sb.和某人分享某物
spread v. 传播，蔓延，展开
Version n. 形式、样式、版本
此处是现在分词短语作方式状语。
Scientists are learning more every day about the secret ways 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.
此处为“介词＋关系代词”引导的定语从句，其中介词in由先行词ways的搭配决定。
科学家对于植物互相交流的秘密方式的认识与日俱增。谁知道呢？也许有一天，我们对植物交流有了足够的了解，便能够亲自与它们“交谈”。
