问答题The prospect of war with Iran is beginning to look real. The hardening of positions in both Tehran and Washington over the past week has brought relations to their lowest point since the Iran hostage crisis that began in 1979.
问答题The importance of agriculture cannot be overstated. More than 50 percent of the world's labor force is employed in agriculture. The distribution in the early 1980s ranged from 67 percent of those employed in Africa to less than 5 percent in North America. In Western Europe, the figure was about 16 percent; in Eastern Europe and the Soviet Union, about 32 percent; and in Asia, about 68 percent.
Farm size varies widely from region to region. Recently the average for Canadian farms was about 186 ha (about 460 acres) per farm, and for U.S. farms, about 175 ha (about 432 acres). The average size of a single landholding in the Philippines, however, may be somewhat less than 3.6 ha (less than 9 acres), and in Indonesia, a little less than 1.2 ha (less than 3 acres).
Size also depends on the purpose of the farm. Commercial fanning, or production for cash, is usually done on large holdings. The plantations of Latin America are large, privately owned estates worked by tenant labor. Single-crop plantations produce tea, robber, cocoa. Wheat farms are most efficient when they comprise some thousands of hectares and can be worked by teams of people and machines. Australian sheep stations and other livestock farms must be large to provide grazing for thousands of animals.
Individual subsistence farms or small-family mixed-farm operations are decreasing in number in developed countries but are still numerous in the developing countries of Africa and Asia. A "back-to-the-land" movement in the U.S. reversed the decline of small farms in New England and Alaska in the decade from 1970 to 1980.
The conditions that determine what will be raised in an area include climate, water supply, and terrain.
Over the 10,000 years since agriculture began to be developed, peoples everywhere have discovered the food value of wild plants and animals and domesticated and bred them. The most important are cereals such as wheat, rice, barley, com and rye.
Agricultural income is also derived from non-food crops such as robber, fiber plants, tobacco, and oilseeds used in synthetic chemical compounds. Money is also derived from raising animals for pelt.
Much of the foreign exchange earned by a country may be derived from a single commodity; for example. Sri Lanka depends on tea. Denmark specializes in dairy products. Australia in wool. and New Zealand and Argentina in meat products. In the U.S., wheat has become a major foreign exchange commodity in recent years.
The importance of an individual country as an exporter of agricultural products depends on many variables. Among them is the possibility that the country is too little developed industrially to produce manufactured goods in sufficient quantity or technical sophistication. Such agricultural exporters include Ghana with cocoa, and Myanmar with rice. On the other hand. an excep-tionally well-developed country may produce surpluses not needed by its own population; this has been true of the U.S., Canada, and some of the West European countries.

问答题美国公司常常谈论他们在培训员工上所花费的大量资金，事实上与日本或德国的公司相比，他们在员工技能上的投入却少得多。他们所投入的资金更多地集中在专业和管理层员工身上。用于培训工人的有限投入也更加局限于进行下一项工作所必须的具体技能，而不是用于可能吸收新技术的一些基础的背景技术。

2．就像其他每个消费电子产品公司做的那样，索尼公司在最近的消费类电子产品展会上推出大量产品，这些产品是用来把网络视频放到电视上。在同时举行的Macworld展会上，苹果公司总裁史蒂夫·乔布斯推出具有同样功能的苹果电视。

问答题国际金融危机给中国带来了前所未有的困难和挑战。主要表现在：经济下行压力明显加大，进出口继续下滑，工业生产明显放缓，部分企业生产经营困难，就业难度加大。这场国际金融危机与中国发展方式转变、经济结构调整的关键时期不期而遇，新的挑战与既有矛盾相互交织，加大了我们解决问题的难度。
为应对国际金融危机冲击、保持经济平稳较快发展，中国及时调整宏观经济政策，果断实施积极的财政政策和适度宽松的货币政策，形成了进一步扩大内需、促进经济增长的一揽子计划。我们大规模增加政府支出，实施总额4万亿元人民币的两年投资计划，实行结构性减税政策，多次降息和增加银行体系流动性，大范围实施产业调整振兴规划，大力推进科技创新和技术改造，大力加强节能减排和生态环境保护，继续调整国民收入分配格局，大力拓展国内市场特别是农村市场，大幅度提高社会保障水平。
现在，这些措施已取得初步成效、呈现出积极迹象，国内消费需求比较旺盛，投资需求稳步提高，社会大局保持稳定。这表明中国的应对思路是符合实际的，政策是积极有效的。中国为应对国际金融危机冲击采取的一系列举措不仅对本国经济、而且对区域经济乃至世界经济都将产生积极影响。

问答题1．“技术转让”的基本设想是：发达国家利用新发现开发技术会给发展中国家带来适用的成果。

问答题Because the aircraft industry needs ever-increasing quantities of aluminium plate, new equipment has been designed to automate the making of it. It includes a huge heat-treatment furnace, a crane that lifts hot metal plates without damaging them, and a computer system that can manage the complete flow of work.
Five years ago, Europe's aircraft industry needed only 8,000 tonnes of aluminium plate a year for its products. Last year the figure reached 21,800 tonnes. By 2004 it should total 30,000 tonnes. Each airliner contains 180 tonnes of it. That is why the plant is being rebuilt to increase both the quality and the amount of its product.
Aluminium is alloyed with other metals and cast into ingots, and the surface of the ingots is smoothed off. After pre-heating, it is rolled in a mill that can take 3.75-m-wide slabs. The new equipment can make the process more efficient and can produce a better product. For example, computers control the temperature of the hot plates, the rate at which they pass through the mill, the speed of cooling it with water, and so on.
The new plant can handle twice the throughput of the one that it is replacing, thanks to the completely automated and computerized process.
问答题There is an ever-widening gap between black male college enrollees and their female and white counterparts, says the American Council on Education (ACE).
Twenty years ago, according to ACE's "Annual Status Report on Minorities in Higher Education," 30 percent of African American male high school graduates (ages 18 to 24) were enrolled in college, compared with 28 percent of same-age black females and 41 percent of white males.
Now, some 37 percent of black men are enrolled, compared with 42 percent of African American women and 44.5 percent of white males. So while there are more black males enrolling in college today than 20 years ago, other groups have outstripped them in enrolling and, even more importantly, in retention rates.
The graduation rate of black men is lower than that of any group. Only 35 percent of black males enrollees graduated within six years from colleges in 1996, compared with 59 percent of white males, 46 percent of Hispanic men, 41 percent of American Indian males and 45 percent of the black women who entered the same year.
Surveys and reports are hinting that the country's educational apparatus is stacked against the black male. Fewer than one in five students of color have graduated from high school, have a set of college-prep courses on their high school transcripts and "demonstrate basic literacy" -- the necessities for being "college ready."
Another glaring problem is that black males are disproportionately labeled as discipline and behavioral problems and fast tracked out of high schools through expulsions and suspensions.
As if that's not enough, says ACE's William Harvey, there's a virtual drying up of federal aid-to-education grant money coupled with jacked-up tuitions, which make it necessary for low-income students to assume an average ＄ 20,000 debt to finish a four-year curriculum.
"For those in the lower economic category, the availability of financial aid determines who gets to go to college and who doesn't," observes Harvey.
Harvey points out that, over the years, federal funding has undergone a "complete reversal," from "a 70 percent to 30 percent grant-to-loan ratio 20 years ago" to the exact opposite today.
"An 18-year-old male will be more inclined to say, 'I want money in my pocket now' and attempt to get a job," adds Harvey. "But many take on the debt, become part-time students, work 20-plus hours a week and become five-year students at a four-year college."
The inequity of that educational apparatus is especially clear when you look at the black males who persevere -- those who go on to finish high school, earn a bachelor's degree and even finish grad school.
A recently released Census report shows that, whether they have a high school diploma or a master's degree, black men will earn roughly 25 percent less than Whites.
