If someone asks you if trees can talk to each other, you may say no. But scientists are listening to trees in whole new ways. Now they think the answer to that question is yes.
Trees don’t talk to each other on the wind. They talk with the help of fungi(真菌) deep underground. Scientists sometimes call this the “web”(网), because it’s a bit like an internet for trees.
How does it work? Tree roots are covered in fine white hyphae(菌丝), the underground part of mushrooms. The hyphae’s job is to take in minerals(矿物质) and water from the soil. The fungi use some of themselves and pass some to the trees they stick to. In exchange, they get some of the sugar the trees make. These thin fungi can connect many trees for miles underground. And trees can use the fungi network to exchange food and compounds(化合物) with each other.
Scientists discovered this when they were studying how carbon(碳) travels through a tree. They fed one tree a special kind of carbon, and checked where it went in the roots and leaves. To their surprise, they also found the special carbon in the roots of nearby trees. The trees were sharing!
Trees in a forest can use the underground fungi network to help each other. They send sugar to neighbours who are sick or don’t get enough sun. They can also use the network to warn each other of danger. If a tree is being bitten by insects, it makes a special thing. Then, other trees get this through the fungi network and their neighbours also start making this compound, before the insects arrive. That way, all the trees do better.
So, although trees may be quiet, they can say a lot to you if you know how to listen.

解析
【分析】
这是一篇科普类阅读理解，围绕“树木能否通过地下真菌网络交流”展开，设置4道题，分别考查细节理解、指代猜测、主旨大意。解题思路为：先通读全文把握核心内容，再针对每道题，定位原文对应信息，逐一分析选项，排除不符合原文的干扰项，确定正确答案。
【解析】
19题：根据文章第二段“Trees talk with the help of fungi deep underground”可知，树木通过地下真菌交流。观察选项，A图是树上的鸟、B图是风吹树叶、C图是地下的蘑菇、真菌与树根、D图是树上的虫子，只有C符合树木交流的方式，故选C。
20题：根据第四段内容，科学家给一棵树喂特殊碳，追踪发现附近树木的根中也有该特殊碳，从而发现树木能共享物质，对应选项C；A选项研究昆虫、B选项用真菌网络（是交流方式而非发现方法）、D选项观察蘑菇生长均不符合原文，故选C。
21题：第五段第一句主语是“Trees”，划线“They”指代前文的主语，即树木，故选A。
22题：文章开头提出“树木能否交流”的问题，中间阐述树木交流的方式与证据，结尾呼应主题，核心围绕“树木是否能交流”展开，对应选项C；A、B、D选项均偏离文章核心，故选C。
【答案】
