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。Communicatewithsb.和某人交流aswellas和，也IntensivereadingWithuslongbelievingthattalkingplantsarefantasy，newresearchhasrevealedsomethingamazing:itappearsthatplantscancommunicateafterall．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。revealv.揭露，表明，展示，显示afterall毕竟，终究

“with复合结构”在句中多作状语，也可以作定语。常见的结构有：(1)with＋宾语＋doing(4)with＋宾语＋adv.(2)with＋宾语＋done(5)with＋宾语＋todo(3)with＋宾语＋adj.(6)with＋宾语＋介词短语[练通]——单句语法填空(1)Withwinter__________(come)on，it'stimetobuywarmclothes.(2)Withallthethingssheneeded____________(buy)，shewenthomehappily.(3)Withnothing______(do)，Tomsleepsathome.(4)Themancamein，withabottle______hishand.comingboughttodoin[写美]——句式升级(5)(普通表达)TheCollegeEntranceExaminationisdrawingnear,sothestudentsfeelgreatpressure.(高级表达)________________________________________________,thestudentsfeelgreatpressure.(with复合结构)WiththeCollegeEntranceExaminationdrawingnearIthasbeenknownforsometimethatplantsusechemicalstocommunicatewitheachother.Thishappenswhenaplant,sayabeanplant,getsattackedbyinsects.Theplantreleases
