单选题{{B}}Directions:{{/B}} Read the following passage. For each numbered blank there are four choices marked A, B, C and D. Choose the best one and mark your answers on ANSWER SHEET 1. The role of governments in environmental management is difficult but inescapable. Sometimes, the state tries to manage the resources it owns, and does so badly. Often, {{U}}(21) {{/U}}, governments act in an even more harmful way. They actually subsidize the exploitation and {{U}}(22) {{/U}} of natural resources. A whole {{U}}(23) {{/U}} of policies, from farm-price support to protection for coal-mining, do environmental damage and (often) {{U}}(24) {{/U}} no economic sense. Scrapping them offers a two-fold {{U}}(25) {{/U}}: a cleane r environment and a more efficient economy. Growth and environmentalism can actually go hand in hand, if politicians have the courage to {{U}}(26) {{/U}} the vested interest that subsidies create. No activity affects more of the earth's surface than farming. It shapes a third of the planet's land area, not {{U}}(27) {{/U}} Antarctica, and the proportion is rising. World food output per head has risen by 4 per cent between the 1970s and 1980s mainly as a result of increases in {{U}}(28) {{/U}} from land already in {{U}}(29) {{/U}}, but also because more land has been brought under the plough. Higher yields have been achieved by increased irrigation, better crop breeding, and a {{U}}(30) {{/U}} in the use of pesticides and chemical fertilizers in the 1970s and 1980s. All these activities may have {{U}}(31) {{/U}} environmental impacts. For example, land clearing for agriculture is the largest single {{U}}(32) {{/U}} of deforestation; chemical fertilizers and pesticides may {{U}}(33) {{/U}} water supplies; more intensive farming and the abandonment of fallow periods {{U}}(34) {{/U}} exacerbate soil erosion; and the spread of monoculture and use of high-yielding varieties of crops have been accompanied by the {{U}}(35) {{/U}} of old varieties of food plants which {{U}}(36) {{/U}} some insurance against pests or diseases in future. Soil erosion threatens the productivity of land in both rich and poor countries. The United States, {{U}}(37) {{/U}} the most careful measurements have been done, discovered in 1982 that about one-fifth of its farmland was losing topsoil at a rate {{U}}(38) {{/U}} to diminish the soil's productivity. The country subsequently {{U}}(39) {{/U}} a program to convert 11 per cent of its cropped land to meadow or forest. Topsoil in India and China is {{U}}(40) {{/U}} much faster than in America.

单选题It"s true that high-school coding classes aren"t essential for learning computer science in college. Students without experience can catch up after a few introductory courses, said Tom Cortina, the assistant dean at Carnegie Mellon"s School of Computer Science. However, Cortina said, early exposure is beneficial. When younger kids learn computer science, they learn that it"s not just a confusing, endless string of letters and numbers—but a tool to build apps, or create artwork, or test hypotheses. It"s not as hard for them to transform their thought processes as it is for older students. Breaking down problems into bite-sized chunks and using code to solve them becomes normal. Giving more children this training could increase the number of people interested in the field and help fill the jobs gap, Cortina said. Students also benefit from learning something about coding before they get to college, where introductory computer-science classes are packed to the brim, which can drive the less-experienced or -determined students away. The Flatiron School, where people pay to learn programming, started as one of the many coding bootcamps that"s become popular for adults looking for a career change. The high-schoolers get the same curriculum, but "we try to gear lessons toward things they"re interested in," said Victoria Friedman, an instructor. For instance, one of the apps the students are developing suggests movies based on your mood. The students in the Flatiron class probably won"t drop out of high school and build the next Facebook. Programming languages have a quick turnover, so the "Ruby on Rails" language they learned may not even be relevant by the time they enter the job market. But the skills they learn—how to think logically through a problem and organize the results—apply to any coding language, said Deborah Seehorn, an education consultant for the state of North Carolina. Indeed, the Flatiron students might not go into IT at all. But creating a future army of coders is not the sole purpose of the classes. These kids are going to be surrounded by computers—in their pockets, in their offices, in their homes—for the rest of their lives. The younger they learn how computers think, how to coax the machine into producing what they want—the earlier they learn that they have the power to do that—the better.

单选题 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.
