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

It is curious how often sympathy for the old and infirm takes a form. which actually humiliates them. Their friends, with good will, sometimes lean forward to
rearrange their neckwear, touching their hair or patting their faces--things they would never presume to do, unasked, to one of their contemporaries. An equally
humiliating habit is to talk about old people in front of them as if they were not there, discussing their health. It is now universally accepted that children should be encouraged to do as much as they can for themselves in order to develop their brains and muscles, but so few
people today seem to have time to allow the elderly the same means of keeping their minds and muscles active. They perform. innumerable services for the old that they
would be much better left to do, even with a struggle, for themselves. Convenient flats, "motherly" visitors, or organized entertainments cannot make up for the fundamental need which must be satisfied--the need to retain to the end
of life human dignity and the respect of one's fellows.Many people are not aware that it is rather rude to ______.A.talk casually about old people in front of them as if they were not thereB.show sympathy for the oldC.take care of the old when they are not illD.pat the faces of the contemporaries
