Online services are managed by a host system that maintains a base of information available to satellite users. Users of so-called “dumb“ terminals (i.e.those without processing capability) simply access the information base via programs stored on the system. Personal computer (PC) users typically access the host through a modem(调制解调器). A PC software program serves as an interface (接口) between the server and a PC, allowing the user to operate through the online system and select different databases using a keyboard or a mouse. National and regional online systems usually have local telephone numbers that PC modems can call to access either a local information base or an indirect long-distance connection, thus reducing long-distance telephone fees. Some online systems allow users to copy large volumes of information onto a local memory storage device, which also reduces the time the user is connected to the online system. Besides offering a great number of different information bases, ranging from full-text journal libraries to reports of missing children, online services allow users to, for example, reserve airline tickets, buy stocks, purchase goods, and communicate with other users. In exchange for the service, users usually pay a monthly membership fee. They may also pay to connect to various databases on the service or to download information.Online services work by providing users with ______. a base of information dumb terminals a host system a satellite

In many countries in the process of industrialization, overcrowded cities present a major problem. Poor conditions in these cities, such as lack of housing, inadequate sanitation(卫生) and lack of employment, bring about an increase in poverty, disease and crime. The over-population of towns is mainly caused by the drift of large numbers of people from the rural areas. These people have become dissatisfied with the traditional life of farming, and have come to the towns hoping for better work and pay. One possible solution to the problem would be to impose registration on town residents. Only officially registered residents would be allowed to live in the towns and the urban population would thus be limited. In practice, however, registration would be very difficult to enforce(推行); it would cause a great deal of resentment(不满), which would ultimately lead to violence. The only long-term solution is to make life in the rural areas more attractive, which would encourage people to stay there. This could be achieved by providing encouragement for people to go and work in the villages. Facilities in the rural areas, such as transport, health and education services should be improved. Education should include training in improved methods of farming and other rural industries, so as to develop a more positive attitude towards rural life. The improvement of life in the villages is very important, because the towns themselves cannot be developed without the simultaneous or previous development of the rural area.What does the word “urban“ (Line 2, Para. 3) mean? Of the city. Out of work. In a bad condition. Of enormous size.
