For years scientist have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more    41    than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired, to    42     eye-pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists    43    that every modern house has some kind of indoor pollution. People began to    44    the problem in the early 1970s, when it was that builders began making houses and offices which did not waste energy. To do this they built buildings that    45    the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to    46    harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control    47    for building green plants. Scientist do not really know how plants control air pollution. They believe that a plant’s leaves take in the pollutants. In exchange the plant produces oxygen    48    its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each    49    different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.

  Comparisons were drawn between the development of television in the 20^th century and the spread of printing in the 15th and 16th centuries. Yet much had happened __47__. As was discussed before, it was not until the 19th century that the newspaper became the dominant pre-electronic medium, following in the wake of the pamphlet and the book and in the __48__ of the periodical. It was during the same time that the communications revolution __49__ up, beginning with transport, the railway, and leading on through the telegraph, the telephone, radio, and motion pictures into the 20th-century world of the motor car and the airplane. Not everyone sees that process in perspective. It is important to do so. It is generally recognized, however, that the __50__ of the computer in the early 20th century, followed by the invention of the integrated circuit during the 1960s, radically changed the process, although its impact on the media was not immediately __51__. As time went by, computers became smaller and more powerful, and they became “personal” too, as well as __52__, with display becoming sharper and storage capacity increasing. It was within the computer age that the term “information society” began to be widely used to describe the __53__ within which we now live. The communications revolution has __54__ both work and leisure and how we think and feel both about place and time, but there have been controversial views about its economic, political, social and cultural implications. “Benefits” have been weighed __55__ “harmful” outcomes. And generalizations have proved difficult.
