Human beings, as biologists have suggested, possess an inborn desire to connect with and understand other life forms. However, people, especially in big cities, often lead rather isolated lives. In a study of British schoolchildren, it was found that children by age eight were much more familiar with characters from television shows and video games than with common wildlife. Without modern technology, a small pond could be an amazing world filled with strange and beautiful plants, insects, birds, and animals. When we lack meaningful interaction(交互) with the world around us, and sometimes even with our families and friends, we seek to understand and communicate with things that exist only in our imaginations or on a computer screen.

The world of make-believe is not necessarily bad. But when the world of fantasy becomes the only outlet(出路) for our sense of wonder, then we are really missing something. We are missing a connection with the living world. Other wonderful worlds exist all around us. But even more interesting is that if we look closely enough, we can see that these worlds, in a broad sense, are really part of our own.

52. The popularity of The Lord of the Rings proves

A. the close connection between man and the fantasy world

B. the wonderful achievements of fantasy literature

C. the fine taste of moviegoers around the world

D. the general existence of the sense of curiosity

53. What can we infer from the underlined sentence in Paragraph 3?

A. People are far less familiar with the world of fantasy.

B. The world around us could serve as a source of wonder.

C. The world of fantasy can be mirrored by a small and lively pond.

D. Modern technology prevents us from developing our sense of wonder.

54. If our sense of wonder relies totally on the world of make-believe, we will

A. fail to appreciate the joy in our lives

B. be confused by the world of make-believe

C. miss the chance to recognize the fantasy world

D. be trapped by other worlds existing all around us

55. What is the main purpose of the passage?

A. To show us the hidden beauty in our world.

B. To warn us not to get lost in the fantasy world.

C. To argue against the misuse of the sense of wonder.

D. To discuss the influence of the world of make-believe.

四:任务型阅读(共10小题;每小题1分,满分10分)

请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。

For more than twenty years scientists have been seeking to understand the mystery of the‘‘sixth sense"of direction.By trying out ideas and solving problems one by one,they are now getting closer to one answer.

One funny idea is that animals might have a built-in compass(指南针).

Our earth itself is a big magnet(磁体).So a little magnetic needle that swings freely lines itself with the big earth magnet to point north and south.When people discovered that idea about athousand years ago and invented the compass,it allowed sailors to navigate (航海)on oceanvoyages, even under cloudy skies.

Actuallly the idea of the living compass came just from observing animals in nature.

Many birds migrate twice a year between their summer homes and winter homes.Some of them fly for thousands of kilometers and mostly at night.Experiments have shown that some birds can recognize star patterns.But they can keep on course even under cloudy skies.How can they do that?

A common bird that does not migrate but is great at finding its way home is the homing pigeon.Not all pigeons can find their way home.Those that can are very good at it,and they have been widely studied.One interesting experiment was to attach little magnets to the birds’ heads to block their magnetic sense—just as a loud radio can keep you from hearing a call to dinner.On sunny days, that did not fool the pigeons.Evidently they can use the sun to tell which way they are going.But on cloudy days,the pigeons with magnets could not find their way.It was as if the magnets had blocked their magnetic sense.

Similar experiments with the same kind of results were done with honeybees.These insects also seem to have a special sense ot direction.

In spite of the experiments,the idea of an animal compass seemed pretty extraordinary.How would an animal get the magnetic stuff for a compass?

An answer came from an unexpected source.A scientist was studying bacteria that live in the mud of ponds and marshes.He found accidentally little rod-like bacteria that all swam together in one direction—north.

Further study showed that each little bacterium had a chain of dense particles inside,which proved magnetic.The bacteria had made themselves into little magnets that could line up with the earth’s magnet.

The big news was that a living thing,even a simple bacterium,can make magnetite.That led to a search to see whether animals might have it.. By using a special instrument called magnetometer,scientists were able to find magnetite in bees and birds,and even in fish.In each animal,except for the bee.the magnetic stuff was always in or closer to the brain.
