Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and the throat and is believed to be related to cancer of the bladder(膀胱) and the oral cavity(口腔). Male cigarette smokers have a higher death rate from heart disease than non-smoking males.
Female smokers are thought to be less affected be cause they do not breathe in the smoke so deeply. The majority of physicians and researchers consider these relationships proved to their satisfaction and say. "Give up smoking. If you don't smoke, don't start". Some competent physicians and research workers - though their small number is dwindling(减小) even further-are less sure of the effect of cigarette smoking on health. They consider the increase in respiratory (呼吸的) diseases and various forms of cancer may possibly be explained by other factors in the complex human environment - atmospheric pollution, increased nervous stress, chemical substances in processed food, or Chemical pesticides that are now being used by farmers in vast Quantities to destroy insects and small animals. Smokers who develop cancer or lung diseases, they say, may also, by coincidence, live in industrial areas, or eat more canned food. Gradually, however, research is isolating all other possible factors and proving them to be statistically irrelevant. While all tobacco smoking affects life expectancy and health, cigarette smoking appears to have a much greater effect than cigar or pipe smoking. However, nicotine(尼古丁)consumption is not diminished by the latter forms, and current research Indicates relationship between all forms of smoking and cancer of the mouth and throat. Filters and low tar(焦油) tobacco are claimed to made smoking to some extent safer, but they can only marginally reduce ,not eliminate, the hazards.

Representatives of Callahan Media Associates (CM [A] announced today that the news agency would attempt to buy the National Broadcasting System (NBS), the second largest television and radio network in the United States. Ronald Callahan, son of Jessica Callahan, who started CMA, told reporters that he expects his company's offering price to be high enough to win out over other offers. He indicated that NBS executives had already discussed reorganization plans that might result from a CMA takeover.
A native of the United Kingdom, Jessica Callahan began to buy newspapers, magazines, and radio stations in the United States eight years ago, and CMA now owns or controls more than fifteen news organizations here. Before she became a leader in media in this country, she had established her family-owned company as one of the most important forces in British TV and newspapers. Callahan started her news career more than twenty-five years ago, and she had worked as a reporter on three different papers when she took the job of editor of England's Birmingham Herald(伯明汉先驱报), a newspaper that had been experiencing financial difficulties for several years. Her success in raising the news reporting standards as well as making the Herald into a profitable business gained Callahan the attention and respect of the British news establishment. By the time she was 35, she had become a publisher and started CMA, which is now one of the largest media organizations in the world.
Callahan had never visited the United States before she came to Miami and became the publisher of the Miami Journal almost eight years ago, but she had been reading the newspaper for several years, and she said that she liked the paper's style. After she had owned the Journal for just over a year, she bought a small radio station in Georgia, and in the next five years she went on to acquire news organizations in several different parts of the country.
If CMA becomes the owner of NBS, for the first time it will have control over a nationwide TV network. In an interview last week, Philip Rosen, the president of NBS, said that he was not very happy about the purchase. He agreed that Callahan and CMA had done a lot to help American newspapers become more financially secure, but he expressed fears that the new management was going to make news coverage on NBS irresponsible. He stated that he hoped he could remain with NBS but said that this might not be possible.
