It appears that plants can communicate after all.
It has been known for some time that plants use chemicals to communicate with each other.
More surprisingly, plants also use sound tocommunicate.
Most surprisingly of all, plants have an amazing system of communication that link nearly every plant in a forest.
Maybe one day we will know enough about plant communication to be able to talk with them ourselves.

An observational journal about the sunflower
1 June
Germination （使发芽）
Covered with 1/2 cm of moist soil, the sunflower seed takes five to 12 days to come up after being planted. Water has been added regularly and the hard seed coat softens in the damp soil to allow the first root to pierce downwards and the first leaves to push to the soil surface.
6 July
Growth
The root continues to grow downward. The single stem grows hollow and smooth, revealing large spade-shaped leaves from the growing tip. Gradually, the plant‘s growing tip reveals the first hints of development of the flower bud. The plant stem becomes more woody.
26 July
Flowering
About three weeks after the flower bud first becomes visible at the tip of the sunflower stem, it enlarges and begins to reveal a flattened disk. Over the course of one week, the yellow ray florets, the disk florets bloom across the core of the sunflower blossom. It is yellow, looking beautiful.
1. Talking plants have long been a thing of myths and legends.Many cultures have stories of talkingtrees that give advice as well as warnings to people.Alexander the Great and Marco Polo were saidto have visited such a tree in India.And in somemodern stories, such as the film Avatar, trees cancommunicate with animals and people.
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―一例如电影《阿凡达》—一中，树可以与人类和动物沟通交流。
课文
2. With us long believing that talking plants arefantasy, new research has revealed somethingamazing: it appears that plants can communicateafter all.
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。
3. It has been known for some time that plantsuse chemicals to communicate with each other.This happens when a plant, say a bean plant, getsattacked by insects.The plant relcases tiny amountsof chemicals from the leaves that are being eaten.This is like a warning, or a call for help: "Tm beingattacked! "When another bean plant detects thechemicals from its injured neighbour, it starts torelease its own, different chemic-als.Some of thesechemicals drive insects away.Others attract insects -the wasps! The wasps kill the insects that are eatingthe bean plants.Scientists hope to learn more aboutthis plant warning system, so that we can use it togrow crops without pesticides.
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一—黄蜂!黄蜂会杀死那些啃食豆类植物的昆虫。科学家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。
4. More surprisingly, plants also use sound to communicate.People can't hear these souncls, butplants are making them. Some plants make noiseswith 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 ishelpful, or unfriendly. Some trees make clickingnoises when there is not enough water, indicatingdrought is arriving.
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。
5. Most surprisingly of all, plants have an amazingsystem of communication that can link nearlyevery plant in a forest. Scientists call this systemthe "wood wide web”.It is in some ways similarto the Interner we use. While the Internet is aworldwide network of computers linked by cables and satellites, the wood wide web is linked underground by fungi.
然而最令人惊奇的是,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。
This fungal network links the roots of different plants to each other.Using the wood wide web, plants can shareinformation and even food with each other.For example, some pine trees can send foodto smaller pine trees to help them grow. Butjust like our own Internet, the wood wideweb has its own version of “cybercrime”. Plants can steal food from each other, orspread poisons to attack other plants.Perhaps one day scientists will learn how to create a “firewall”to help prevent these attacks within the woodwide web.
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。
6. Scientists are learning more every day aboutthe secret ways in which plants talk to each other. Who knows Maybe one day we will know enough about plant comunication to be able to“talk” with themourselves.
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。

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一—黄蜂!黄蜂会杀死那些啃食豆类植物的昆虫。科学家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。

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。
