Even without taking the technology to its limits, the idea of education as a lifelong process is catching on throughout the industrialized world. Already, working adults who pursue their studies part-time make up roughly half of students taking college courses in the United States.
However, there is debate in scholar circles about how far new technology should be used for teaching academic subjects in which personal contacts between teacher and student are still vital. Britain's Open University, for example, a world leader in distance education, has embraced information technology cautiously, believing it to be no substitute for books and the exchange of ideas at live tutorials and summer schools.
But the Open University is also moving with the tide. It has set up a "knowledge media institute" to explore ways of adopting information technology. Some teachers are concerned about this trend, arguing that the heavy investment that students are expected to make in computer and communications equipment contradicts the concept of "open" cost, of course, is and important factor in many developing countries, where few people have computers or even phones. Rather than uniting the world, the new technologies could lead to societies of information haves and have-nots.

In Africa, people learned to send messages by beating on a series of large drums (鼓). Each drum was kept within hearing distance of the next one. The drum beats were sent out in a special way that all the drummers understood. Though the messages were simple, they could be sent at great speed for hundreds of miles.
In the eighteenth century, a French engineer found a new way to send short messages. In this way, a person held a flag in each hand and the arms were moved to various positions representing different letters of the alphabet (字母表). It was like spelling out words with flags and arms.
Over a long period of time, people sent messages by all these different ways. However, not until the telephone was invented in America in the nineteenth century could people send speech sounds over a great distance in just a few seconds.

Perhaps the warmest part of the country is the southwest, which consists of the counties of Devon and Cornwall. The warm Gulf Stream flows across the North Atlantic Ocean from the Gulf of Mexico and makes the coastal regions of the southwest quite warm. Palm trees, bamboo (竹) and many semi-tropical (亚热带的) plants grow well in the southwest of England.Flowers and vegetables ripen(成熟) as much as a month earlier than those elsewhere. Farmers in the area obtain a higher price for their vegetables and flowers because they are ready earlier. (77) In winter there may be several feet of snow in other parts of England but there will probably be no snow at all in the southwest. This may be one of the reasons why the southwest is one of England's most popular holiday areas.

A.one hundred miles
B.three hundred miles
C.one hundred and fifty miles

The high point in railroad building came with the construction of the first transcontinental sys tem. In 1862 congress authorized two western railroad companies to build lines from Nebraska west ward and from California eastward to a meeting point, so as to complete a transcontinental crossing linking the Atlantic seaboard with the Pacific. The Government helped the railroads generously with money and land. Actual work on this project began four years later. The Central Pacific Company, starting from California, used Chinese labor, while the Union Pacific employed crews of Irish labourers. The two groups worked at remarkable speed, each trying to cover a greater distance than the other. In 1869 they met at a place called Promontory in what is now the state of Utah. Many visitors came there for the great occasion. There were joyous celebrations all over the country, with parades and the ringing of church bells to honour the great achievement.
The railroad was very important in encouraging westward movement. It also helped build up industry and farming by moving raw materials and by distributing products rapidly to distant markets. In linking towns and people to one another it helped unify the United States.
The major problems with America' s railroad system in the mid-19th century lay in ______.
A.poor quality rails and unreliable stopping systems
