Imagine a world in which children would be the rulers and could decide not only the outcom

e of each and every occurrence, but also dictate the very structure and form. of the environment. In this world, a child's wildest thoughts would become reality, limited only by the extent of his or her imagination. While such a world might sound both fantastic and frightening, at least from a logical, adult perspective, it does exist. What's more, it has been in existence for some time and is populated by hundreds of thousands of children who spend hours within its boundaries experimenting and learning. This world is not real, at least not in the traditional sense, but exists within a computer and is generated by an educational programming language called LOGO. Unlike other computer languages and programs that are designed to test children and provide applications that formally dispense information, LOGO allows children, even preschool children, to be in total control. Children teach the computer to think and as a result develop and sharpen their own reasoning abilities.In the imagined world ______ would restrict children's wildest thoughts.A.the limits of their imaginationB.the structure and form. of the environmentC.the reality of lifeD.the roles of the society

第5题

Man's first roan invention, and one of the most important inventions in history, was the w

heel. All transportation and every machine in the world depend on it. The wheel is the simplest yet perhaps the most remarkable of an] inventions, because there are no wheels in nature no living thing was ever created with wheels. How, then, did man come to invent the wheel？ Perhaps some early hunters found that they could carry it. However, the logs themselves weighed a lot.

It must have taken a great prehistoric thinker to imagine two thin slices of log connected, at their centers by a string stick, this would roll along just as the logs did, yet be much lighter and easier to handle, thus the wheel and axle came into being and with them the first cart.

The wheel is important because ______ .

A．it was man' s first real invention

B．all transportation depends on it

C．every machine depends on it

D．both B and C

No one knows exactly how many disabled （残废的) people there are in the world, but estimat

No one knows exactly how many disabled (残废的) people there are in the world, but estimates suggest the figure is over 450 million. The number of disabled people in India alone is probably more than double the total population of Canada.

In the United Kingdom, about one in ten people have some disability. Disability is not just something that happens to other people. As we get older, many of us will become less mobile (可动的), hard of hearing or have failing eyesight.

Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many progressive disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form. of a mental illness. All are affected by people's attitude towards them.

Disabled people face many physical barriers. Next time you go shopping or to work or visit friends, imagine how you would manage if you could not get up steps, or on to buses and trains. How would you cope if you could not see where you were going or could not hear the traffic？ But there are other barriers: prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through, so it is important to draw attention to these barriers and show that it is the individual person and their ability, not their disability, which counts.

The first paragraph points out that ______.

A．it is possible to get an exact figure of the world's disabled people

B．there are many disabled people in the world

C．the number of disabled people in India is the greatest

D．India has not much more disabled people than Canada

第10题

For me, scientific knowledge is divided into mathematical sciences, natural sciences or sc

iences dealing with the natural world (physical and biological sciences), and sciences dealing with mankind (psychology, sociology, all the sciences of cultural achievements, every kind of historical knowledge).

Apart from these sciences is philosophy, about which we will talk later. In the first place, all this is pure or theoretical knowledge, sought only for the purpose of understanding, in order to fulfill the need to understand that is intrinsic and con-substantial to man. What distinguishes man from animals is that he knows and needs to know. If man did not know that the world existed, and that the world was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldn't be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance, because they also contribute to defining him as man and permit him to pursue a life increasingly more truly human.

But even while enjoying the results of technical progress, man must defend the primacy and autonomy of pure knowledge. Knowledge sought directly for its practical applications will have immediate and foreseeable success, but not the kind of important result whose revolutionary scope is for the most part unforeseen, except by the imagination of the Utopians. Let me recall a well-known example. If the Greek mathematicians had not applied themselves to the investigation of conic section zealously and without the least suspicion that it might someday be useful, it would not have been possible centuries later to navigate far from shore. The first men to study the nature of electricity could not imagine that their experiments, carried on because of mere intellectual curiosity, 'would eventually lead to modern electrical technology, without which we can scarcely conceive of contemporary life.

Pure knowledge is valuable for its own sake, because the human spirit cannot resign itself to ignorance. But, in addition, it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly.

The author does not include among the sciences the study of

A．literature.

B．chemistry.

C．astronomy.

D．anthropology.
