听力原文： The Unite Nations (UN) is the largest organization on the earth because it involves most of the countries in the world. The UN has the most important goal in the world z peace. Although all people and countries want peace, it is often forgotten because of anger, power, and many other complex human emotions. Because peace is not as strong as war, because peace is not as loud as war, because peace is not as active as war, it is often lost in the fast pace of life. After the two major world wars of the last century, the people of the world formed the UN in order to work cooperatively toward peace and better lives for all.

The UN has not been as successful toward this goal as many hoped. Yet it is the best organized group working toward peace. With more than 130 members, nearly all the countries in the world, the UN has a good chance of achieving its goals. With more money and more of a commitment from some of the most powerful members, the UN could surely be more effective than it is today. However, disagreements and power struggles among the members have so far prevented the achievement of peace.
