1、Passage 2 Do Plants Talk to Each Other? 1 When a leafy plant is under attack, it doesnt sit quietly. 2 Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. 3 These chemicals
2、come from the injured parts of the plant and seem to be an alarm. 4 What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short. 5 Scientists have found that all kinds of plants give out VOCs when being attacked. 6 Its a plants way of crying out
3、. 7 But is anyone listening？Apparently. 8 Because we can watch the neighbors react.9 Some plants pump out smelly chemicals to keep insects away. 10 But others do double duty. 11 They pump out perfumes designed to attract different insects who are natural enemies to the attackers. 12 Once they arrive
4、, the tables are turned. 13 The attacker who was lunching now becomes lunch.14 In study after study, it appears that these chemical conversations help the neighbors. 15 The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the al
5、arm and knew what to do.16 Does this mean that plants talk to each other？ Scientists dont know. 17 Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. 18 Perhaps the neighbors just happened to “overhear” the cry. 19 So
6、 information was exchanged, but it wasnt a true, intentional back and forth.20 Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate than the world we can see and hear. 21 Our senses are weak. 22 Theres a whole lot going on.一 单词和短语Words and expressions* leafy /li

8、.包德恩两位科学家就曾在报道中指出，被昆虫咬伤的小枫树会散发出邻近植物可以感知到的特殊气味。3 这些化学物质来自植物受伤的部位，似乎是一种警报。4植物在空气中发散出的是一种被称为挥发性有机化合物的化学混合物，简称VOCs。5科学家发现，所有植物在受到攻击时都会释放出挥发性有机化合物。6这是植物的一种哭泣。7但有人在听吗？显然是的。8因为我们可以观察到周边植物作出了反应。9一些植物发出难闻的化学物质以阻止昆虫靠近。10但另有一些植物却能执行双重任务。11它们发出一些香气，旨在吸引各种攻击者的天敌。12 它们一到达，形势就会发生扭转。13本来想饱餐一顿的攻击者反倒变成了美味的午餐。14 一次次的研
9、究表明，利用化学物质的交流能够帮助周边的植物。15第一个被攻击的植物遭受的伤害往往更严重，但是周边的植物，通常说来，会更安全，因为它们能 “听”到警告并且知道该怎么做。 16这就意味着植物之间会相互交流吗？科学家们也不知道。17也许第一株受攻击的植物只是由于疼痛而大声呼喊或者是给自己的分枝发出信息。因此，实际上，这是自言自语。18也许周边植物无意中听到了呼喊声。19所以信息自此交流，但这并不是真正有意识的信息互通。20 150多年前，查尔斯达尔文想象出一个比我们所能看到和听到的世界更加复杂和亲密的世界。21 我们的器官无法感知这些事情。22有很多事情正在发生。三 理解Comprehension

15、ate with each other 17 conveying a message, in fact 19 intended, interaction/communication五Scientists find that plants under attack produce volatile organic compounds to drive bugs away or even chemicals that attract the bugs natural enemies. Besides, they also find that the neighbors usually suffer less damage than the first plant thanks to the chemical warning. Scientists still dont know whether the communication among plants is intentional.
