听力原文：The United States has the largest my in the world. The size of an economy is usually described in terms of the Gross Domestic Product, The Gross Domestic Product, or G. D. P., is the value of all goods and services produced in a country in a year. In 2004, the United States had a G. D.P. estimated at close to 12 million million dollars. What percentage of that was agriculture？ The government says just 9/10 of one percent, Farm workers make up an even smaller percentage of American labor: 7/10 of one percent.
In 2004, almost 20 percent came from industry -- and almost 80 percent came from services. The number of farms continues to decrease in America, whereas farm earnings have risen to record levels in recent years. Agricultural productivity continues to increase because of new technology and methods. But the Agriculture Department estimates that 9 percent of farm income last year came from government payments. That number is expected to decrease in the future.
Exports have provided American farmers with an average of about 25 percent of their money for the last fifteen years. Canada and Mexico are two of the three biggest markets for American farmers. In fact, in 2002, Canada replaced Japan for the first time as the top buyer of American agricultural exports. The Department of Agriculture says exports to the European Union are slowing. But exports to other countries within the Americas and to Asia are growing.

听力原文：A new report from the United Nations says the world must do much more to reduce the number of underweight children. It says one in four children under the age of five is seriously underweight.
Poor nutrition is linked to more than half of all child deaths. Experts say it is a cause in more than 5.5 million deaths each year in children under five years old. The United Nations Children's Fund, UNICEF, published the report last week. The report measures progress toward reaching the first Development Goal of this century: reducing extreme poverty and hunger. In 2000, world leaders approved a list of eight goals to reach within 15 years. The aim is to improve the lives of the world's poor.
UNICEF says China has already met the target of a 50 percent reduction in the number of underweight children. It says China has cut the rate from 19 percent to 8 percent. A growing economy and government efforts to reduce poverty and improve nutrition are given credit. But UNICEF says at current rates, the goal of cutting poor nutrition in half world- wide will not be met. It says rates of underweight children in developing countries have dropped by just 5 percentage points since 1990.
The head of UNICEF, Ann Veneman, says nutrition affects life at every point of development, starting before a child is even born. But she says too many people do not know about its importance, and how serious a problem there is around the world.
Why does the UN call for the reduction of the number of underweight children？
