intelligent dolphin

Some animals are smarter than humans. Take the intelligent dolphin as an example. After just a few weeks in captivity, it can train humans to throw it fish.

Notes:

1. Some animals are smarter than humans.

有一些动物比人类还聪明。

“human”和“human being"都是指“人类”。但前者通常是相对于动物而言的;后者更强调有血有肉有感情的人类，因为being是表示生命的存在。

2. Take the intelligent dolphin as an example.

以聪明的海豚为例。

句中的“as an example”也可以写成for example。

3. After just a few weeks in captivity, it can train humans to throw it fish.

只要几个星期的囚禁之后，它就可以训练人类扔鱼给它。

在海豚看来，也许它们觉得是它们在训练人类，只要他们转圈、跳高，人类就会喂它们鱼。
