(单选题)

If animals eat one Golden Wattle tree’s leaves, the tree can ______.

A.kill the animals with a special smell

B.tell other trees to come to protect it

C.warn other trees against the animals on the phone

D.send defense messages to the neighboring plants

参考答案：D

参考解析：

细节理解题。根据第三段中的“when an animal eats the tree’s leaves, the amount(数量)of poison increase in the other leaves... It’s like the injured leaves telephoning the others telling them to fight together against the enemy”和第四段的第一句“The tree also sends defense messages to neighboring plants by giving out a special smell”可知，当有动物吃合欢树的叶子时，其他叶子的毒性会加重，就好像是受伤的叶子通过电话告知其他叶子一起对抗敌人一样，但是并非是真的打电话。而且它还会通过分泌一种特殊气味给其他的植物发送防御信息，而不是自己用特殊气味杀死敌人，所以A项、B项、C项错误。故选D。
