Ⅲ. Read and answer the questions.
Do you know that trees can talk? They don't use words like we do, but they have their own secret ways of communicating. Scientists have made amazing discoveries in understanding this "Wood Wide Web".
Most of the conversation happens underground. A network of tiny fungi (真菌) connects the roots of different trees. Through this network, trees can share food and water. A strong and old tree can help a young and weak tree by sending nutrients (养分). They can also send warning messages. If a tree is being attacked by insects, it can give out chemicals through its leaves and roots. Nearby trees then receive the messages and start producing their own chemicals to protect themselves.
This exploration into the forest shows us that a forest is more than just a collection of trees. It is a community where plants help each other. Looking into forests in this way helps us enjoy the complex and wonderful world of nature.
(
A. By using words and sounds.
B. By touching their roots and leaves.
C. Through a network of fungi connecting their roots.
D. Through the food and water they get from humans.
(
A. To help young trees grow stronger.
B. To help old trees to find more water.
C. To invite other trees to share nutrients in food.
D. To tell other trees to make protective chemicals.

A. Trees can communicate and help each other.
B. Fungi are the most important part of the forest.
C. Scientists have discovered new insects in the forest.
D. Young and weak trees help scientists look into nature.

解析
【分析】
1. 第1题：要确定树木主要的交流方式，需定位到文章第二段的关键内容，文中明确提到树木的交流大多在地下进行，是依靠连接树根的真菌网络实现的，据此可对应正确选项。
2. 第2题：关于警告信息的目的，需查看第二段中树木遇虫害时的行为描述，受攻击的树木发出信号后，附近树木会做出制造防护化学物质的反应，由此可判断警告信息的作用。
3. 第3题：主旨大意题需梳理全文脉络，文章开篇点明树木有独特的交流方式，接着介绍树木通过真菌网络分享养分、传递警告，最后总结森林是植物互助的社区，核心是树木能交流且互相帮助，以此确定主旨选项。
【解析】
1. 第1题：根据文章第二段“Most of the conversation happens underground. A network of tiny fungi (真菌) connects the roots of different trees.”可知，树木主要通过连接树根的真菌网络进行交流，故选C。
2. 第2题：由第二段“If a tree is being attacked by insects, it can give out chemicals through its leaves and roots. Nearby trees then receive the messages and start producing their own chemicals to protect themselves.”可知，警告信息的作用是告知其他树木制造防护化学物质来保护自己，故选D。
3. 第3题：通读全文，文章围绕树木的交流方式以及树木之间互相帮助的行为展开，核心主旨是树木能够交流且彼此互助，故选A。
【答案】
Ⅲ. 1. C 2. D 3. A
