In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight against enemies. Over millions of years, plants have developed their own defense system(防卫系统). Chemicals are used by plants to survive(幸存). By 3 / 8 B．if C．while D．since making their leaves, flowers, roots and fruits poisonous(有毒的) to enemies, plants can fight back. One such plant is the Golden Wattle(金合欢花) tree. The British scientist David Cameron has found when an animal eats the tree's leaves, the amount(数量) of poison increases in the other leaves. “It's like the injured leaves telephoning the others to fight together against the enemy，” he said. The tree also sends defense messages to its neighboring plants by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees' leaves, he will die. Every kind of plant or tree is good at producing a special set of chemicals. Herbivores(食草动物), like rabbits, can safely eat the leaves of one tree, but they may be poisoned by its neighbor. In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest. 根据短文内容，判断下列句子正误，正确的用“A”表示，不正确的用“B”表示.。 11．Plants can fight against enemies by using chemicals. 12．American scientist David Cameron has found how the Golden Wattle tree fights together against the enemy. 13．Golden Wattle trees in the nearby 10 meters produce more poison within 45 minutes. 14．Rabbits may be poisoned by its neighbor. 15．An animal can be protected easily by even a small area of forest. 4 / 8
