(单选题)
From the first 2 paragraphs, we can learn that ______.
A.plants can do nothing against their enemies
B.chemicals are quite useful for plants to survive
C.an antelope can always run away from a strong lion
D.leaves, roots, flowers and fruits of plants are poisonous
参考答案:B
参考解析:
推理判断题。根据第一段最后一句“Even plants have their own ways of fighting off enemies”可知,植物拥有自己的方式对抗敌人,所以A项错误;根据第二段第二句“Chemicals are widely used for survival”可知,化学物质对于植物的生存来说非常重要。所以B项正确;根据第一段第一句“it is surprising to see how an antelope can escape a lion’s attack”可知,当我们看到一只羚羊逃过狮子的袭击会非常意外,但是未强调羚羊总是会逃过狮子的袭击,所以C项错误;根据第二段最后一句“By making their leaves, flowers, roots and fruits distasteful or poisonous(有毒的)to enemies, plants can fight back”可知,植物会通过使自己的叶子、花、根、果实有毒来对抗敌人,但是不代表所有植物的这些部位都有毒。所以D项错误。故选B。
