We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we will let others know soon. But do you know that a tree can talk and share news? It sounds strange, but it's true that some trees can also communicate with each other. Of course, no tree moves lips and says words just as people do.
Willow trees(柳树）are the best-known of these trees. When insects(昆虫）begin eating a willow tree, the tree gives out a special smell at once. This smell tells the other willow trees that insects are coming near. All of them quickly make a chemical（化学物质）in their leaves. This chemical is bad for the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.
Next time when you take a walk near the trees, maybe the trees are "talking" to each other quietly. And when someone says that trees cannot "talk", please tell them that even trees can "talk" to each other, too.

A. words B. winds

A. parts of a tree B. parts of a mouth
C. roots D. stems

解析
【分析】
本题为自然生态主题的植物科普类阅读理解题，共3道选择题，分别考查细节理解和词义猜测能力。解题思路：1. 第1题需定位原文中柳树交流的方式，匹配对应描述；2. 第2题结合上下文语境（树木不会像人一样动lips说话）和常识猜测词义；3. 第3题定位昆虫飞走的原因，找到原文对应内容。
【解析】
1. 细节理解题：根据第二段“When insects begin eating a willow tree, the tree gives out a special smell at once. This smell tells the other willow trees that insects are coming near.”可知柳树通过气味交流，故选C。
2. 词义猜测题：根据第一段“no tree moves lips and says words just as people do”，人说话需要动嘴唇，lips是嘴的一部分，故选B。
3. 细节理解题：根据第二段“All of them quickly make a chemical in their leaves. This chemical is bad for the insects. The insects do not like it and they fly away soon.”可知是柳树叶子里的化学物质让昆虫飞走，故选D。
