问答题Practice 11 If you ask an Englishman about the Press in his country, he will almost certainly begin talking about the morning daily and Sunday “national newspapers”, all of which now have their head offices in London. Later, almost as an afterthought, he may go to talk about the provincial morning dailies, the London and provincial evening papers, and finally the weekly local papers. The dominating position of the national daily morning papers is due to the smallness of the country, with every large town in England and Wales able to be reached by train in less than five hours from London. A paper printed in London around midnight can be at any breakfast table in England the next morning, except in remote country districts. All over the country, most people read the same newspapers and the dominant position of the London papers may reflect a lack of regional identity. The national dailies are generally classed as either “quality” (The Times, the Guardian and the Daily Telegraph) or “popular”.
