With over 300,000 plants species on Earth,theres no doubt that they have highly developed senses to stay alive and thrive.But while some of their features may be compared to taste,sight,touch and smell in humans,have you ever wondered-can plants think?世界上共有三十多万种植物,毫无疑问,为了繁荣昌盛 它们的感官都已高度进化。不过,尽管一些特征可以与人类的味觉 视觉 触觉和嗅觉做比,你是否曾想过 植物会思考吗?On land,the cumulative mass of plants is 1000 times highter than that of animals.But these plants are immobile and cant move around in their environment;which is,seemingly,a pretty big evolutionary disadvantage.This has forced plants to adapt in amazing ways that often go unnoticed by the naked eye.陆地上,植物总重量比动物高1000倍。但这些植物都是固定不动的,似乎在进化中这也很不利。这点迫使植物采取些容易被眼睛忽略的奇特方式。Smell something funny?Plants do too-and they react to these chemicals in the air.For example,when fruits start to ripen,they release a chemical called ethylene.And when neighbouring fruits sense this pheromone,they ripen faster,so that all fruits mature at the same time.Plants also give off scents which attract insects to sp their pollen.味道怪味了?植物也能闻,并会对空气中的化学物质做出反应。比如,水果在成熟时会释放出一种叫乙烯的物质。当周围植物感测到这种信息素时,它们会更快成熟,而所有的水果就能同时成熟了。植物也会释放出吸引昆虫传粉的气味。In particular,the amazing carrion flowers grow tiny hairs,feel warm and smell like rotting flesh in an attempt to mimic a dead corpse.This is to attract flies and beetles as pollinators.On the other hand,when a plant is attacked by an insect,animal or pathogen,it knows.When acacia trees are grazed by animals,they quickly react by producing chemicals called tannins,which make their leaves unappetizing and tough to digest.特别地 大王花会长出腐肉味的绒毛 籍此模仿死尸。这是为了吸引传粉者 苍蝇和甲虫。另一方面 当植物受到昆虫 植物或病菌的侵害时 它也知道。当金合欢树被动物盯上时 它也会立即产生单宁酸,这让它们的叶子更难吃 难以消化。Some even produce enough toxin to kill the animal.Perhaps more impressive are some corn and cotton plants,which when eaten by caterpillars,release chemicals in the air that attract parasitic wasps,who fly in and ultimately kill the insects.有些甚至会产生足以杀死动物的毒素。更惊人的是一些玉米类和棉类植物 在被毛虫啃咬时,它们会释放化学物质 吸引寄生蜂,后者受吸引而来 杀死昆虫。On some level,they communicate with the wasps.Crazy as it seems,even sound recordings of caterpillars chewing leaves,trigger this response.Without any from of touch,the plants react,as if they can hear.On a large scale,plants also work together.A web of underground fungi can connect tree roots in forests,allowing them to exchange nutrients and information.一定程度上说,它们能与黄蜂交流。让人诧异的是,毛虫啃咬叶子的录音也会引起这种反应。没有任何形式的触碰,植物也像有听觉一样做出反应。多数情况下,植物也会齐心协力。地下的真菌网会将森林里的树根相连,让它们交换养分和信息。Using radioactive isotopes,scientists discovered that trees share water and nutrients with others in need.Large trees nourish smaller shaded ones until they are tall enough to reach sunlight,And trees that stay green all year round share nutrients with trees that lose their leaves in winter,helping them through the season.Which is then repaid in the summer months,like a transactional exchange.Some scientist refer to this as the ;wood-wide web;.科学家通过同位素观测发现 树木会与有需求者分享水和养料。大树会与受遮蔽的小树分享养分 直到它们能受到日照。四季常青的树木会与冬季落叶的树木分享养分 帮助它们过冬。在夏天它们得到偿还的养分 像是生物交换。一些科学家称此为“树联网”。Perhaps the most shocking fact,is that some plants seem to have memory.Mimosa pudica plants,are those leafy plants that close up when touched.This reflex is meant to scare away insects that land on them.In an experiment on these reflexes,scientists notice that when dropped from 15cm.they would close when they hit the groud,Not so surprising.But after repeating the drop 4 or 5 times,some of the plants stopped closing.as though they had realized the stimulus wasnt harmful.If they were shaken istead,they would close,but any time they were dropped from this same height,they stayed open.this effect lasted for weeks-the plants had memories.更惊人的是 一些植物似乎有记忆能力。含羞草 一种受触碰时叶子会合拢的植物。这种反射是为了吓唬落在它们身上的植物。在一项关于这种反射的实验中 研究者发现从15厘米高出落下 它们的叶子会在落地时合拢 没什么奇怪的。但重复四五次后 一些植物不再合拢(叶子)了,似乎它们也发现这种刺激不会伤害它们。受到摇晃时 叶子就会合拢,但无论何时 从同样的高度掉下 叶子仍然张开。这种效果会持续数星期,植物也有。Of course,plants dont have brains or other cells and organs that we deem necessary for intelligence.Brains and neurons are irreplaceable,but plants are immobile and often attacked,so they must be able to survive after part of them is eaten,or destroyed.A brain just wouldnt work.But if you measure intelligence or thought as the ability to solve problems,interact with an environment,and even work in groups,then plants are incredibly smart.当然 植物没有大脑或者其他“智力”不可或缺的器官或细胞。大脑和神经无可替代,但植物无法移动,也常受攻击,在部分被吃掉或毁坏后 它们还得能活下去。大脑没什么用。但如果你将智力或思维视作解决问题的能力,与周围环境的交互 甚至团队合作力,那么植物相当聪明。Its something to think about next time youre munching down on a piece of broccoli!下次嚼西兰花时,好好想想这点吧!201503/361976。

Getting kids to behave isnt always easy. The key is to start looking at discipline as teaching, not punishment.让孩子们行为端正并不容易。关键是通过教育,而不是惩罚的方式来管教。You Will Need你需要Rules规矩Consequences for breaking them违反规矩要承担的后果Self-control自我控制Leading by example以身作则ed front统一战线Positive reinforcement正面的心理强化Steps步骤STEP 1 Establish consequences1.设立规定和违反规定的后果Establish rules and consequences for breaking them, then enforce the consequence as close to the bad behavior as possible. You want the child to connect their misbehaving with its repercussions. And be consistent: If you punish children for something one day and let it slide the next, theyll keep testing how much they can get away with.设立规定和违反规定的后果,然后以尽可能接近孩子不良行为的方式来执行。你希望孩子把不良行为和后果联系起来。始终如一地执行:如果某一天因为他的错误作出惩罚,另一天却原谅他们,他们会不断挑战尝试你可以放过他们多少次。Never negotiate with a child; it gives them the power.不要和孩子谈判,这会给他们更大的能量。STEP 2 Try not to spank them2.不要用巴掌打他们Resist the urge to spank them; studies show that children who are spanked regularly are more likely to become physically abusive themselves,as well as take part in risky or violent sexual behavior as teens and young adults.克制用巴掌打他们的冲动。研究发现,经常被巴掌打的孩子更有可能虐待自己,青少年和成年时期更可能参加冒险活动或出现暴力性行为。STEP 3 Use your indoor voice3.保持声音冷静Keep your voice calm and level when correcting your childs behavior or explaining why theyre being punished. Save the screaming for serious situations, like when theyre about to do something dangerous.纠正孩子的行为或者解释他们为何受到惩罚时,声音保持冷静。只有严重的情况下才大喊大叫,比如当他们正要做危险的事情的时候。If theyre not doing anything destructive or hazardous, try ignoring them. Children often act up simply to get attention.如果他们没有做毁灭性的或危险的事情,试着忽略他们。孩子们行为过火通常是为了吸引注意力。STEP 4 Lead by example4.树立榜样Lead by example. Dont punish your children for something you do or your partner does.树立榜样。不要因为你和你的伴侣同样做的事情惩罚孩子。STEP 5 Present a united front5.建立统一战线Always back up your partners disciplinary decisions, and make sure they back yours. Its easier to keep kids in line if parents present a united front.一定要持伴侣的约束决定,确保他们也持你的。如果家长表现出统一战线,要约束孩子就更加容易。STEP 6 Reinforce good behavior6.强化好的行为Reinforce good behavior. Parenting experts say its more effective to compliment or reward a child after theyve been good than to bribe them to behave.强化好的行为。育儿专家表示,孩子做出好的行为后赞扬或奖励他们比贿赂他们做出好的行为更加有效。Forty-five percent of American and Canadian parents interviewed say they use time-outs to discipline their children.45%接受采访的美国和加拿大父母表示,他们利用休息时间来管教孩子。视频听力译文由。201503/364776。
