Professor Martin's report says that children who attend a number of different schools, because their parents have to move around the country, probably make slow progress in their studies. There are also signs, says Professor Martin, that an unusually large number of such children are mentally affected.

　　The professor says, "It's true, my personal feeling is that children should stay in one school. However, our findings are based on research and not on any personal feelings that I or my assistants may have on the subject."

　　Captain Thomas James, an Army lecturer for the past 20 years and him self a father of two, said," I've never heard such rubbish. Taking me for ex ample, no harm is done to the education of my children who change schools regularly－if they keep to the same system, as in our army schools. In my experience, I've known quite a few of them－Army children are as well－adjusted（调整）as any others, if not more so. What the professor doesn't appear to appreciate is the fact that in such situations children will adapt（适应）much better than grown-ups."

　　When this was put to Professor Martin, he said that at no time had his team suggested that all such children were backward or mentally affected in some way, but simply that in their experience there was a clear tendency（倾向）.

　　"Our findings show that while the very bright child can deal with regular changes without harming his or her general progress in studies, the majority of children suffer from constantly having to enter a new learning situation."

No country in the world has more daily newspapers than the USA.　There are almost 2000 of them，as compared with 180 in Japan，164 in Argentina and 111 in Britain.　The quality（质量） of some American papers is quite high and their views are used all over the world.　Excellent newspapers like the Washington Post or the New York Times　have a powerful influence（影响） all over　the country.　However，the Post　and the New York Times　are not national newspapers in the sense that The Times is in Britain of Le Monde is in France，since each American city has its own daily newspaper.　The best of these give detailed（详细的）accounts of national and international news，but many tend to limit themselves to state or city news.?

Like the press（报刊） in most other countries，American newspapers report news from the “exciting” and “relaxing” to the serious.　They try to entertain people as well as give information，for they have to compete with the attraction of television.

Just as American newspapers try to satisfy all tastes，they also try to attract readers of all political parties.　A few news papers support extremist（极端主义者） groups on the far right and on the far left，but most daily newspapers try their best to attract middle-of-the-road Americans who are mainly moderate（温和的）.Many of these papers print materials by well?known journalists of different political and social views，in order to give a balanced picture.?

As in other countries American newspapers can be either responsible（负责任的） or irresponsible，but it is generally accepted that the American press serves its country well and that it has more than once exposed political scandals（丑闻），for example，the Watergate Affair（水门事件）.?
