Scientific experiments have shown again and again that octopuses(章鱼) are pretty smart.They learn quickly，can solve puzzles and remember solutions.

But the big question is why？There are several reasons why

octopus intelligence is a mystery to many biologists.Firstly，biologists believe that intelligent animals such as chimpanzees(黑猩猩) and dolphins develop large complex brains because they live in complex social groups and need to understand each other.Octopuses live alone.Secondly，other intelligent animals have long childhoods when they can learn from their parents.Such animals also generally live for quite a long time，so having a big brain is a good investment.Baby octopuses lose touch with their parents almost immediately after birth and then they only live for six months to a year.Why does this animal need such a large brain？Finally，octopuses are cousins to snails，oysters and mussels—quite primitive(原始的) animals，which appeared on Earth millions of years before mammals did.Generally，biologists believe that intelligence increases as you go higher up the tree of evolution(进化)．With their big brains，octopuses don’t seem to fit this theory at all.They almost seem to be aliens，a strange mystery of the animal world.It’s easy to understand why in Hawaiian folklore，people thought that the octopus was actually the last survivor of a lost universe.

One theory suggests that octopuses and humans perhaps have a lot in common.Like early humans，octopuses are physically much weaker than their predators．They have soft，naked(裸露的) bodies and they can’t swim as fast as many fish and sharks which hunt them.This is why octopuses spend much of their time hiding between rocks or in holes，just as humans learned to make their homes in caves.Octopuses have also learned some very effective techniques for hunting for food and this means that an octopus spends very little of its time(on average just seven percent) looking for food.But what do they think about as they hide away in their holes？Perhaps the cruel turns of evolution，which have left them with large，playful brains but living alone in the dark at the bottom of the ocean...

【解题导语】 本文是一篇议论文。文章对章鱼为何如此聪明进行了探讨。 1．Which of the following about octopuses has been confirmed? A．They have a poor memory. B．They prefer living in groups. C．They usually have a short life. D．They learn a lot from their parents.

C 解析：细节理解题。由第二段中的Baby octopuses lose touch with their parents almost immediately after birth and then they only live for six months to a year.可知，章鱼的寿命不长，只能活半年到一年的时间。

2．Why are octopuses like aliens? A．They come from a different universe. B．They have a very strange appearance.

C．They are the most intelligent creatures under the sea. D．They don’t clearly belong in the pattern of evolution.

D 解析：推理判断题。由第二段中的octopuses are...primitive(原始的) animals，which appeared on Earth millions of years before mammals did...intelligence increases as you go higher up the tree of evolution(进化)可知，章鱼作为一种比哺乳动物出现早几百万年的原始生物，拥有大的脑容量并如此聪明，这很明显不符合生命演化的过程，因此被看作是外来生物。

3．What does the underlined word “predators” in the last paragraph probably refer to?

A．Cousins. C．Partners.

B．Enemies. D．Parents.

B 解析：词义猜测题。由最后一段中的They have soft，naked(裸露的) bodies and they can’t swim as fast as many fish and sharks which hunt them.可知，章鱼是一种软体动物，体力弱，没有捕杀它们的天敌游得快。
