[单项选择]The United States is the United Nations’ biggest deadbeat. Conservatives in Congress, led by Senator Jessie Helms, stopped Washington from paying its dues until the UN reduced its assessment and made other changes. Now, thanks to the hard work of Richard Holbrooke, America’s UN representative, and his staff, the UN has agreed to trim the U. S. share of financial burdens for the UN general budget and for peacekeeping. Mr. Helms, who has praised the deal, should release the dues he has been holding hostage— $582 million of the $1.3 billion the UN says it is owed.
The new formula would reduce the U. S. contribution to the general UN budget to 22% from the current level of 25%—a symbolic difference of only $34 million a year. Washington, which has been paying just over 30% of the peacekeeping budget, would now pay 27%—a difference of $80 million to $120 million a year—and that percentage will drop further. While poor countries would not pay more, the dues of other wealthy nations woul

The United States government publishes guidelines for appropriate nutrient intakes. These are known as the Recommended Dietary Allowances (RDAs) and are updated regularly based on new research in nutrition. RDAs are suggested amounts of calories, protein, and some minerals and vitamins for an adequate diet. For other dietary substances, specific goals must await further research. However, for the U.S. population as a whole, increasing starch and fiber in one’’s diet and reducing calories (primarily from fats, sugar, and alcohol) is sensible. These suggestions are especially appropriate for people who have other factors for chronic diseases due to family history of obesity, premature heart disease, diabetes, high blood pressure, and high blood cholesterol, or for those who use tobacco. Snacks can furnish about one-fourth of the calorie requirements among teenagers. Those snacks should also provide much of the day’’s allowances for protein, minerals, and vit
