I believe that animals possess greater intelligence than most people think. But plants? I've never considered the possibility of plant intelligence. The idea seems absurd.

Yet I've had friends argue that plant intelligence might exist. "What are the differences between plants and animals?" they ask, and then they argue about certain species that seem to share the intelligence of both plants and animals.

New research suggests that plants communicate via "networks". Plant communication is not idea, and cannot indicate that its is a kind of intelligence, but it is still interesting.

Recent research from Vidi researcher Josef Stuefer at the Radboud University Nijmegen shows that plants have their own chat systems that they can use to warn each other. Therefore plants are not boring and passive organisms that just stand there waiting to be cut down or eaten up. Many plants form internal communication networks and are able to exchange information networks and are able to exchange information efficiently.

Many herbal plants such as strawberries and clovers (三叶草)naturally form networks.

Individual plants remain connected with each other for a certain period of time by means of runners (plant stems that grow along the ground and put down roots to form new plants). These connections enable the plants to share information with each other via internal channels. They are therefore very similar to computer networks. But what do plants chat to each other about?

Recently Stuefer and his colleagues were the first to prove that clover plants warn each other via the network links if danger is nearby . If one of the plants is attacked by caterpillars (毛虫)，the other members of the network are warned via an internal signal. Once warned the intact (完好无损的)plants strengthen their chemical and mechanical (机体的)resistance so that they are less attractive to advancing caterpillars. Thanks to this early warning system, the plants can stay one step ahead of their attackers. The research has shown that this significantly limits the damage to the plants.

Again, I don't believe this reflects intelligence, but it's is certainly fascinating.

阅读下文，完成第下面的题。

　　人君之欲平治天下而垂荣名者，必尊贤而下士。夫朝无贤人，犹鸿鹄之无羽翼也，虽有千里之望，犹不能致其意之所欲至矣；故绝江海者托于船，致远道者托于乘，欲霸王者托于贤。是故吕尚聘，而天下知商将亡，而周之王也；管夷吾、百里奚任，而天下知齐、秦之必霸也。纣用恶来，齐用苏秦，秦用赵高，而天下知其亡也。

　　齐景公伐宋，至于岐堤之上，登高以望，太息而叹曰：“昔我先君桓公，长毂八百乘以霸诸侯，今我长毂三千乘，而不敢久处于此者，岂其无管仲欤!”弦章对曰：“臣闻之，水广则鱼大，君明则臣忠；昔有桓公，故有管仲；今桓公在此，则车下之臣尽管仲也。”

　　杨因见赵简主曰：“臣居乡三逐，事君五去，闻君好士，故走来见。”简主闻之，绝食而叹，跽而行，左右进谏曰：“居乡三逐，是不容众也；事君五去，是不忠上也。今君有士，见过八矣。”简主曰：“子不知也。夫美女者，丑妇之仇也；盛德之士，乱世所疏也；正直之行，邪枉所憎也。”遂出见之，因授以为相，发而国大治。

　　子路问于孔子曰：“治国何如?”孔子曰：“在于尊贤而贱不肖。”子路曰：“中行氏尊贤而贱不肖，其亡何也?”曰：“中行氏尊贤而不能用也，贱不肖而不能去也；贤者知其不己用而怨之，不肖者知其贱己而雠之。贤者怨之，不肖者雠之；怨雠并前，中行氏虽欲无亡，得乎?”

　　无常安之国，无恒治之民；得贤者则安昌，失之者则危亡，自古及今，未有不然者也。明镜所以昭形也，往古所以知今也。夫知恶往古之所以危亡，而不务袭迹于其所以安昌，则未有异乎却走而求逮前人也。（节选自刘向《说苑·卷八·尊贤》，有改动）

①致远道者托于乘，欲霸王者托于贤

②管夷吾、百里奚任，而天下知齐、秦之必霸也

D．③④⑥

A．作者认为人君树立功名、成就霸业抑或破家亡国、身败名裂，根本的原因在于能否尊贤而下士。

B．齐景公感慨自己有三千辆兵车却不敢在宋国久留，弦章告诉他，要多有几个管仲一样的贤臣就好了。

C．杨因是一个有争议的人，而赵简主用鞭辟入里的分析力排众议，委以重任，表明赵简主能够尊贤用贤。

D．孔子认为尊贤与贱不肖是治国的重要方略，中行氏因为“尊贤而不能用”“贱不肖而不能去”而导致灭亡。
