阅读理解。
Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the

existence of creatures and even whole societies beyond our everyday lives.

This sense of wonder is universal. Look at the efforts that scientists have made to find out whether life of

some kind exists on Mars, and the popularity of fantasy (幻想) literature or movies like The Lord of the Rings.

This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But

have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already

exist all around us?

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.

1. 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

2. 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.

3. 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

4. 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.

第2题
The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer,and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.

Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion (拥挤). One proposed solution to this problem is the automated highway system.

When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail,the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car&39;s movements.

The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.

Choose correct answers to the question:

One significant improvement in the future car will probably be ________.

A.its power source

B.its driving system

C.its monitoring system

D.its seating capacity

What is the author’s main concern?A.How to render automobiles pollution-free.

B.How to make smaller and safer automobiles.

C.How to solve the problem of traffic jams.

D.How to develop an automated subway system.

What provides autos with electric power in an automated highway system?A.A rail.

B.An engine.

C.A retractable arm.

D.A computer controller.

In an automated highway system, all the driver needs to do is ________.A.keep in the right lane

B.wait to arrive at his destination

C.keep in constant touch with the computer center

D.inform the system of his destination by phone

What is the author’s attitude toward the future of autos?A.Enthusiastic.

B.Pessimistic.

C.Optimistic.

D.Cautious.

Sports and games make our bodies strong, prevent us from getting too fat, and keep us healthy. But these are not their only use. They give us valuable practice in making eyes, brain and muscles work together. In tennis, our eyes see the ball coming, judge its speed and direction and pass this information on to the brain~ The brain then has to decide what to do, and to send its orders to the muscles of the arms, legs, and so on, so that the ball is met and hit back where it ought to go. All this must happen with very great speed, and only those who have had a lot of practice at tennis can carry out this complicated chain of events successfully. For those who work with their brains most of the day, the practice of such skills is especially useful.

Sports and games are also very useful for character-training. In their lessons at school, boys and girls may learn about such virtues as unselfishness, courage, discipline and love of one's country; but what is learned in books cannot have the same deep effect on a child's character as what is learned by experience~ The ordinary day-school cannot give much practical training in living, because most of the pupils' time is spent in classrooms, studying lessons. So it is what the pupils do in their spare time that really prepares them to take their place in society as citizens when they grow up. (16) If each of them learns to work for his team and not for himself on the football field, he will later find it natural to work for the good of his country instead of only for his own benefit.

When we play tennis we have to______.

A.use, first, our eyes, then the brain and finally the muscles

B.make our eyes, brain and muscles work almost at the same time

C.use mainly the arms and legs to hit

D.use mainly the muscles so that the ball is met and hit back

In the United States elementary education begins at the age of six. At this stage nearly all the teachers are women, mostly married. The atmosphere is usually very friendly, and the teachers have now accepted the idea that the important thing is to make the chil-dren happy and interested. The old authoritarian (要绝对服从的) methods of education were discredited (不被认可) rather a long time ago-so much so that many people now think that they have gone too far in the direction of trying to make children happy and interestedrather than giving them actual instruction.

The social education of young children tries to make them accept the idea that human beings in a society need to work together for their common good. So the emphasis is on co- operation rather than competition throughout most of this process. This may seem curious, in view of the fact that American society is highly competitive; however, the need for mak-ing people sociable in this sense has come to be regarded as one of the functions of educa-tion. Most Americans do grow up with competitive ideas, and obviously quite a few as criminals, but it is not fair to say that the educational system fails. It probably does succeed in making most people sociable and ready to help one another both in material ways and through kindness and friendliness.

According to the passage, the American elementary education is supposed to make children______.

A.sensible and sensitive

B.competitive and interested

C.curious and friendly

D.happy and co-operative

Advertisement can be thought of "as the means of making known in order to buy or sell goods or services". Advertisement aims to increase people's awareness and arouse interest. It tries to inform. and to persuade. The media are all used to spread the message. The press offers a fairly cheap method, and magazines are used to reach special sections of the market. The cinema and commercial radio are useful for local market. Television, although more expensive, can be very effective. Public notices are fairly cheap and more permanent in their power of attraction. (78) Other ways of in creasing consumer interest are through exhibitions and trade fairs as well as direct mail advertisement.

(79) There can be no doubt that the growth in advertisement is one of the most striking features of the western world in this century. Many businesses such as those handling frozen foods, liquor, tobacco and medicines have been built up largely by advertisement. We might ask whether the cost of advertisement is paid for by the producer or by the customer. Since advertisement forms part of the cost of production, which has to be covered by the selling price, it is clear that it is the customer who pays for the advertisement. How ever, if large—scale advertisement leads to increased demand, production costs are reduced, and the customer pays less.

It is difficult to measure exactly the influence of advertisement on sales. When the market is growing, advertisement helps to in crease demand. When the market is shrinking, advertisement may prevent a bigger fall in sales than would occur without its support. (80) What is clear is that businesses would not pay large sums for advertisement if they were not convinced of its value to them.

Advertisement is often used to ______.

A.deceive customers

B.increase production

C.arouse suspicion

D.push the sale
