①Many cultures have stories of talking trees that give advice as well as warnings to people. Alexander the Great and Marco Polo were said to have visited such a tree in India.New research has found something amazing: it seems that plants can communicate after all.
②It has been known for some time that plants use chemicals(化学物质)to communicate with each other. This happens when a plant gets attacked by insects. The plant gives out chemicals from the leaves that are being eaten. This is like a warning, or a call for help. When another plant gets the chemicals, it starts to give out its own, different chemicals. Scientists hope to learn more about this plant warning system, so that we can use it to grow more crops.
③More surprisingly, plants also use sound to communicate. People can't hear these sounds, but plants are making them. Some plants make noises with their roots. Some trees make clicking noises when there is not enough water.
④Most surprisingly of all, plants have an amazing system of communication that can link nearly every plant in a forest. Scientists call this system the “wood wide web”, which is linked underground by fungi(菌类). It links the roots of different plants to each other. It is in some ways similar to the Internet we use. Using the wood wide web, plants can share information and even food with each other. However, it may lead to bad effects. Plants may use it to steal food from each other, or spread chemicals to attack other plants.
⑤Scientists are learning more every day about the secret ways in which plants talk to each other. Who knows Maybe one day we will know enough about plant communication to be able to “talk” with them ourselves.

12.(9分)小明想利用多用电表和一粗细均匀的铅笔芯测一节干电池的电动势和内电阻,实验步骤如下:
(1)将多用电表调至“欧姆×1”挡,调零后,测量该铅笔芯的电阻,指针指示如图甲所示,则该铅笔芯的电阻R为 (1分)Ω;
(2)将多用电表调至合适的直流电流挡(该挡内阻较小),按如图乙连接电路;
(3)用刻度尺测得铅笔芯连入电路的总长度为L;
(4)多次改变铅笔芯接入电路中PN的长度x,并记录相对应的电表读数;
(5)在坐标纸上画出-x图像如图丙所示,已知该图像的斜率为k,纵轴截距为b,由图像可知,该电池的电动势E= ,内电阻r= (本问结果均用题中所给字母表示);
(6)若不考虑测量中的偶然误差,从实验原理上看,该方法测得的电池的电动势
