apparently. because we can watch the neighbours react.some plants pump out smelly chemicals to keep insects away. but others do double duty. they pump out perfumes designed to attract different insects who are natural enemies to the attackers. once they arrive, the_tables_are_turned. the attacker who was lunching now becomes lunch.in study after study, it appears that these chemical conversations help the neighbors.the damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.does this mean that plants talk to each other? scientists dont know. 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. perhaps the neighbors just happened to “overhear” the cry. so information was exchanged, but it wasnt a true, intentional back and forth. charles darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. our senses are weak. theres a whole lot going on.5what does a plant do when it is under attack?ait makes noises.bit gets help from other plants.cit stands quietly.dit sends out certain chemicals.6what does the author mean by “the tables are turned” in paragraph 3?athe attackers get attacked.bthe insects gather under the table.cthe plants get ready to fight back.dthe perfumes attract natural enemies.7scientists find from their studies that plants can_apredict natural disastersbprotect themselves against insectsctalk to one another intentionallydhelp their neighbors when necessary8what can we infer from the last paragraph?athe world is changing faster than ever.bpeople have stronger senses than before.cthe world is more complex than it seems.dpeople in darwins time were imaginative.答案与解析语篇导读：本文是一篇说明文。研究发现，当多叶植物受到攻击时，它们不会坐以待毙，会发出vocs，以此来保护自己或者与周围的植物通过化学物质进行交流。5d细节理解题。根据“reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get.these chemicals come from the injured parts of the plant and seem to be an alarm”可知，当植物受到伤害时，会分泌一种特殊的化学物质。故选d。6a词义推测题。根据“once they arrive，the tables are turned.the attacker who was lunching now becomes lunch”，一旦它们到达这里然后这些攻击者就会成为植物的午餐，根据语境，故选a。7b细节理解题。根据“ in study after study, it appears that these chemical conversations help the neighbors.the damage is usually more serious on the first plant, but the neighbors，relatively speaking，stay safer because they heard the alarm and knew what to do”可知，植物在必要的时候会通过分泌化学物质，通知周围的植物保持警惕。故选b。8c推理判断题。根据“imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear.our senses are weak.theres a whole lot going on”可知，这个世界远比我们看到或听到的更热闹、更亲密，我们认知能力有限，有很多事仍在继续发生，远比我们想象的要复杂。故选c。con her first morning in america last summer, my daughter went out to explore her new neighborhood alone, without even telling my wife or me. of course we were worried; we had just moved from berlin, and she was just 8. but when she came home, we realized we had no reason to panic. beaming with pride, she told us how she had discovered the little park around the corner, and had made friends with a few local dog owners. when this story comes up in conversations with american friends, we usually meet with polite disbelief. most are horrified by the idea that their children might roam(闲逛) around without adult supervision(监管). a study by the university of california has found that american kids spend 90 percent of their free time at home, often in front of the tv or playing video games. such narrowing of childrens world has happened across the developed world. but german parents are generally much more accepting of letting children take some risks. “we are depriving(剥夺) them of opportunities to learn how to take control of their own lives，” writes peter gray, a research professor at boston college. he argues that this increases the chance that they will suffer from anxiety, depression, and various other mental disorders, which have gone up dramatically in recent decades. i am no psychologist like professor gray, but i know i wont be around forever to protect my girls from the challenges life holds in store for them. and by giving kids more control over their lives, they learn to have more confidence in their own abilities.9hearing the authors daughter exploring the new neighborhood alone, his american friends feel_aworried bproudcdoubtful dterrified10we can conclude from paragraph 3 that _aamerican kids enjoy playing at homebgerman parents are less protective than american parentscgerman kids like taking risks more than american kidsdamerican parents dont limit their childrens activities in their leisure time11its implied from professor grays words that _aparents should always be around their children to protect them from risksbmore and more parents suffer from mental problemscchildren are having more opportunities to take control of their livesdgiving children more freedom is beneficial to their mental development12which of the following words can best describe the authors parenting?aop
