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

Today, moving and changing are as much a part of a modern business way of life as they are
a part of the native American's or the early pioneer's way of life. And the trend is toward even greater mobility, particularly within the management sector of American business.

In the early fifties, only eight or nine out of a hundred young men changed their jobs within the first three years with the company. In the past few years, almost thirty-five percent of the college-graduated work force changed jobs within the same period. These people want to intensify their management training. Since most jobs take only a year to a year and a half to master, in order to continue learning, they have to make a job change. Even company presidents tend to be seen as mobile specialists, staying with one company an average of only five years.

Company presidents in the United States today tend to be young men who begin their careers with educational backgrounds in engineering science, or business management. They have worked for a few years as technical specialists and quickly moved into higher management positions. Most of them were making $ 30 000 per year by the time they reached thirty. On an average, these men have only twenty years working experience at management level when they become company presidents. On the way to the top, they have an average of eleven promotions and seven city transfers.

Friendships remain casual and are usually derived from business contracts. Families of these career men have little time to put down roots in and become part of a community.

In the past, a few men attained high positions through family and social connections; today, high positions go to men who are mobile, and have good educational, backgrounds.

According to the passage, an increasing number of future company presidents might be ______.

A.people who have spent a number of years with one company

B.young people who do not want to move often, but are steady and dependable

C.people who have spent a long time concerned with community affairs

D.young people who have good education and are willing to move around

第6题

Acting is such an over-crowded profession that the only advice that should be given to a y
oung person thinking of going on the stage is " Don't " ! But it is useless to try to discourage someone who feels that he must act, although the chances of his becoming famous are slim. The normal way to begin is to go to a drama school. Then the young actor or actress takes up work with a theatrical company, usually as an assistant stage manager. This means doing everything that there is to do in the theatre:painting scenery, publicity (宣传) , taking care of the costumes (舞台服装) , and even acting in very small parts. It is very hard work indeed. The hours are long and the salary is tiny.

Of course, some people have remarkable chances which lead to fame and success without this long and hard training. Connie Pratt, for example, was just an ordinary girl working in a bicycle factory. A film producer happened to catch sight of her one morning waiting at a bus stop, as he drove past in his car. He stopped and asked if she would like to go to the film studio to do a test, and she thought he was joking. It took the producer twenty minutes to convince Connie that he was serious. The test was successful. And within a few weeks she was playing the leading part opposite one of the most famous actors of the day. But chances like this happen once in a blue moon!

From the very beginning, the author puts it clearly that acting is a profession______.

A.for ambitious people only

B.for young people only

C.too difficult for young people

D.sought after by too many people

It used to take Redwood City, California police hours to locate gunfire. Now, they have a
new tool that helps them find the gunfire quickly. This new tool is called the ShotSpotter. The police began using the ShotSpotter in 1995. They wanted to cut down on gunfire in their city.

One ShotSpotter covers a square mile. Eight microphones are put on the roofs of buildings. These microphones pick up gunfire noise. It only takes seven seconds to report the gunfire to the police. Then a red dot on the police map shows where the action is.

The ShotSpotter really works well. It locates the gunfire within 20 to 40 feet plus or minus. Redwood City police are very happy with the ShotSpotter. They think it might have helped catch the D.C. sniper.

ShotSpotters cost a lot of money. One of them sells for $200,000. Despite the cost, ShotSpotters can be a big help in fighting crime.

Eight microphones placed on rooftops ______.

A.talk to police

B.warn the public

C.listen for gunfire

D.play rap music

第9题

There is a popular belief among parents that schools are no longer interested in spelling.
No school I have taught in has ever ignored spelling or considered it unimportant as a basic skill.

There are, however, vastly different ideas about how to teach it, or how much priority it must be given over general language development and writing ability. The problem is how to encourage a child to express himself freely and confidently in writing without holding him back with the complexities of spelling?

If spelling became the only focal point of his teacher's interest, clearly a bright child will be likely to "play safe". He will tend to write only words within his spelling range, choosing to avoid adventurous language. That's teachers often en courage the early use of dictionaries and pay attention to content rather than technical ability.

I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling errors and technical abilities in writing". But it was also a sad reflection on the teacher who had such feelings. The teacher was not wrong to draw attention to the errors, but if his priorities had centered on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more motivation(动力) to seek improvement.

Teachers are different in their opinions about ______.

A.the necessity of teaching spelling

B.the role of spelling in general language development

C.the way of teaching spelling

D.the complexities of the basic writing skills
