第2题
Television, although not essential, has become an important part of most people’s lives. It alters people's ways of seeing the world; in many ways, it supports and sustains (维持) modern life. Television has become a baby-sitter, an introducer of conversations, the major transmitter of culture, a keeper of tradition. Yet when what can be seen on TV in one day is critically analyzed, it becomes evident that television is not a teacher but a sustainer; the poor quality of programming does not elevate (提高)people into greater understanding, but rather maintains and encourages the life as it exists.
The primary reason for the lack of quality in American television is related to both the history of TV programming development and the economics of TV. Television in America began with the radio. Radio companies and their sponsors first experimented with television. Therefore, the close relationship which the advertisers had with radio programs became the system for American TV. Sponsors not only paid money for time within programs, but many actually produced the programs. Thus, in American society, television is primarily concerned with reflecting and attracting society rather than experimenting with new ideas. Advertisers want to attract the largest viewing audience possible. To do so requires that the programs be entertaining rather than educational, attractive rather than challenging.
Television in America today remains, to a large extent, with the same organization and standards as it had thirty years ago. The hope for further development and true achievement toward improving society will require a change in the entire system.
According to the author American television is poor in quality because ______.
A．advertisers are interested in experimenting with new ideas
B．it is still at an early stage of development, compared with the radio
C．the programs have to be developed in the interests of the sponsors for economic reasons
D．it is controlled by radio companies

第5题
Recent research had claimed that an excess of positive ions (离子) in the air can have an ill-effect on people's physical or psychological health. What are positive ions？ Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charges. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorms, earthquakes or when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing made of man-made fibers, or from TV sets, duplicators or computer display screens.
When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suffer nausea (恶心) or even mental disturbance. Animals are also found to be affected, particularly before earthquakes; snakes have been observed to come out of hibernation(冬眠), rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in all effort to foresee such disasters before they hit vulnerable areas such as California.
Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with tumbling streams or waterfalls.
To increase the supply of negative ions indoors, some scientists recommend the use of ionizers : small portable machines which generate negative ions. They claim that ionizers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment.
After all, it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.
According to the passage, static electricity can be caused by
A．using home-made electrical goods.
B．wearing clothes made of natural materials.
C．walking on artificial floor coverings.
D．copying TV programs on a computer.
