In recent speeches at Republican fundraisers, President Bush has taken to criticizing the press for baring government secrets. The outgoing secretary of the Treasury, John Snow, in what may have been his last official act, wrote to The New York Times that in exposing the monitoring of bank transfers, it had undermined a successful counterterrorism program. A house resolution, passed by a party line vote, called on the media to safeguard classified programs. The government has discovered what governments have discovered before, that an undercurrent of hostility towards the news media runs through the country and that there could be political advantage in campaigning against the press in general. The champion press hater, of course, was President Nixon, who told his staff that the press is the enemy, and he proceeded to declare his own private war against the media. In 1969, he had a speech written by speechwriter Pat Buchanan denouncing the media as a "tiny and closed fraternity of privileged men". And he gave it to Vice President Spiro Agnew to deliver. That speech is best remembered today for the line contributed by another speechwriter, William Safire, about "nattering nabobs of negativism". It is not clear that the public hates the press as much as officialdom would like to think. A recent Pew Research report found that public attitudes towards the press have been on a downward track for years. Growing numbers of people questioned the news media’s patriotism and fairness. And yet most Americans continue to say they like mainstream news outlets. And so, as The Christian Science Monitor headlined the other day: "Amid war on terror, a war with the press." You would not expect that I, as a journalist, would exhibit total neutrality in such a war. And so let me quote Justice Potter Stewart in his opinion in the Pentagon Papers ease in 1971: "In the absence of governmental checks and balances present in other areas of our national life, the only effective restraint upon executive policy and power in the area of national defense and international affairs may lie in an enlightened citizenry... Without an informed and free press, there cannot be an enlightened people;" That remains true, even when Mr. Bush proclaims a state of war with the terrorists. We can infer from the passage that ______.

The appeal of the world of work is first its freedom. The child is compelled to go to school; he is under the 1 of authority. Even what he 2 to school may be decided for him. As he grows up,he sees 3 it is to be free 4 school and to be able to choose his job and change it if he doesn’’t like it,to have money in his pocket and 5 to come and go as he wishes in the world. The boys and girls, a year or two older than he is, whom he has long observed, revisit school utterly 6 and apparently mature. Suddenly masters and mistresses seem 7 out of date as his parents and the authority of school a 8 thing. At the moment the adult world may appear so much more real than the school world 9 the hunger to enter it cannot be appeased by exercises in school books, or talk of 10 examinations necessary for entry into professions or the more attractive occupations. This may not be the wisest 11 but it is a necessary part of growing up, for everyone must come sooner or later to the 12 of saying" Really, I’’ve had enough of being taught; I must do a proper job. "Some youths, maturing rapidly because of outside influences,come to this decision 13 than they ought. Yet in a way this is not a bad frame of mind to be in 14 leaving school. At work, the young man makes one of the first great acceptances of life-he accepts the 15 of the material or the process he is working with. The job must be done in accord with some rigid process he cannot 16 . He sees the point of it and in doing so comes to 17 with life. Nothing done in school 18 its will in quite the same way;if it is wet games can be cancelled;if the math master is ill one can 19 with something else. But even the boy delivering papers, like the driver taking out his bus, discovers that one cannot 20 because there is snow on the ground, or the foreman is irritable, or he himself is in a bad mood that morning.
