【解析】本文主要谈论食物链的问题。陆地上的食物链最高段是狮子。海洋里的食物链最高段之一是鲨鱼。人类是所有食物链的最高端。人们发明了工厂，他们污染了空气和河流。脏的河流杀死了鱼。熊不能吃到鱼而死亡。如果我们杀死了食物链一部分，其他的部分也会死亡。我们人类也危险了。我们应该而且我们也能为世界做些什么。

1.句意： 它比许多动物跑的都快，而且它能捕食到最好的食物。根据上文We sometimes call the lion “the king of the jungle” Because it is stronger and more dangerous than other animals.（我们有时称呼狮子“丛林之王”因为它比其他的动物更强壮和更危险。）和下文It is the highest animal in the land food chain.（它是陆地食物链最高级的动物。）结合句意和语境可知选E。

2.句意：它用它的大牙吃他们。根据上文In the sea, the shark is one of the animals at the top of the food chain. It can swim faster than most other sea animals.（在海洋里，鲨鱼是食物链最顶端的动物之一。它能比大多数其他海洋动物游的都快。）结合句意和语境可知选B。
