Soon after his appointment as secretary-general of the United Nations in 1997, Kofi Annan lamented that he was being accused of failing to reform. the world body in six weeks. "But what are you complaining about？" asked the Russian ambassador: "You've had more time than God." Ah, Mr. Annan quipped back, "but God had one big advantage. He worked alone without a General Assembly, a Security Council and [all] the committees."
Recounting that anecdote to journalists in New York this week, Mr. Annan sought to explain why a draft declaration on UN reform. and tackling world poverty, due to be endorsed by some 150 heads of state and government at a world summit in the city on September 14th16th, had turned into such a pale shadow of the proposals that he himself had put forward in March. "With 191 member states", he sighed, "it's not easy to get an agreement."
Most countries put the blame on the United States, in the form. of its abrasive new ambassador, John Bolton, for insisting at the end of August on hundreds of last minute amendments and a line-by-line renegotiation of a text most others had thought was almost settled. But a group of middle-income developing nations, including Pakistan, Cuba, Iran, Egypt, Syria and Venezuela, also came up with plenty of last-minute changes of their own. The risk of having no document at all, and thus nothing for the world's leaders to come to New York for, was averted only by marathon all-night and all-weekend talks.
The 35-page final document is not wholly devoid of substance. It calls for the creation of a Peacebuilding Commission to supervise the reconstruction of countries after wars; the replacement of the discredited UN Commission on Human Rights by a supposedly tougher Human Rights Council; the recognition of a new "responsibility to protect" peoples from genocide and other atrocities when national authorities fail to take action, including, if necessary, by force; and an "early" reform. of the Security Council. Although much pared down, all these proposals have at least survived.
Others have not. Either they proved so contentious that they were omitted altogether, such as the sections on disarmament and non-proliferation and the International Criminal Court, or they were watered down to little more than empty platitudes. The important section on collective security and the use of force no longer even mentions the vexed issue of pre-emptive strikes; meanwhile the section on terrorism condemns it "in all its forms and manifestations, committed by whomever, wherever and for whatever purposes", but fails to provide the clear definition the Americans wanted.
Both Mr. Annan and, more surprisingly, George Bush have nevertheless sought to put a good face on things, with Mr. Annan describing the summit document as "an important step forward" and Mr. Bush saying the UN had taken "the first steps" towards reform. Mr. Annan and Mr. Bolton are determined to go a lot further. It is now up to the General Assembly to flesh out the document's skeleton proposals and propose new ones. But its chances of success appear slim.
Who have recently listened to the story in the first paragraph of the text？
A．Ambassadors.
B．UN officials.
C．The world's leaders.
D．Reporters.

In any country the wages commanded by laborers who have comparable skills but who work in various industries are determined by the productivity of the least productive unit of labor, i.e., that unit of labor which works in the industry which has the greatest economic disadvantage. We will represent the various opportunities of employment in a country like the United States by symbols: A, standing for a group of industries in which we have exceptional, economic advantages over foreign countries; B, for a group in which our advantages are less; C, one in which they are still less; D, the group of industries in which they are least of all.
When our population is so small that all our labor can be engaged in the group represented by A, productivity of labor (and therefore wages) will be at their maximum. When our population increases so that some of the labor will have to be set to work in group B, the wages of all labor must decline to the level of the productivity in that group. But no employer, without government aid, will yet be able to afford to hire labor to exploit the opportunities represented by C and D, unless there is a further increase in population.
But suppose that the political party in power holds the belief that we should produce every thing that we consume, that the opportunities represented by C and D should be exploited. The commodities that the industries composing C and D will produce have been hitherto obtained from abroad in exchange for commodities produced by A and B. The government now renders this difficulty by placing high duties upon the former class of commodities. This meads that workers in A and B must pay higher prices for what they buy, but do not receive higher prices for what they sell.
After the duty has gone into effect and the prices of commodities that can be produced by C and D have risen sufficiently, enterprisers will be able to hire labor at the wages prevailing in A and B, and establish industries in C and D. So far as the remaining laborers in A and B buy the products of C and D, the difference between the price which they pay for those products and the price that they would pay if they were permitted to import those products duty-free is a tax paid not to the government, but to the producers in C and D, to enable the latter to remain in business. It is an uncompensated deduction from the natural earnings of the laborers in A and B. Nor are the workers in C and D paid as much, estimated in purchasing power, as they would have received if they had been allowed to remain in A and B under the earlier conditions.
When C and D are established, workers in these industries______.
A．receive higher wages than do the workers in A and B
B．receive lower wages than do the workers in A and B
C．are not affected so adversely by the levying of duties as are workers in A and B
D．receive wages equal to those workers in A and B
