W: Almost five million people are married each year in the United States. About one in every eight of these weddings takes place in June, the traditional month for weddings. Getting married can be as simple as a five-minute ceremony performed by a judge in a law office. Or it can be a traditional religious ceremony at home, or in a church. The average age of an American woman being married for the first time is about twenty-four years. The average age for a man is twenty-five. Most young men and women get engaged about a year before the wedding. In the Nineteen-Sixties and Seventies, many young Americans decided not to have traditional, formal weddings. Many brides and grooms wrote their own wedding ceremonies. These often included poetry and personal statements about their goals in marriage. Some grooms wore old blue jeans to their weddings. More than a few brides were married in their bare feet. It was not unusual to be married on a sandy beach or on a mountainside. In the last ten years, however, big formal weddings have become popular again. Experts say the average size of formal weddings now is two-hundred guests. Most formal wedding patties are held at hotels or high-priced eating places. There are fresh flowers and paid photographers. Musicians play for dancing, and hired servants present the wedding dinner. A big wedding takes months to plan, and it can cost thousands of dollars. How many people get married in June each year in the United States()

M: Welcome to Yellow Stone National Park. Before we begin our nature walk today, I’d like to give you a short history of our national park service. The national park service began in the late 1800s. A small group of explorers had just completed a month long exploration of the region that is now Yellow Stone. They gathered around the campfire and after hours of discussion, they decided that they should not claim this land for themselves. They felt it should be accessible to everyone so they began a campaign to preserve this land for everyone’s enjoyment. Two years later, in die late 19th century, an Act of Congress signed by President Ulysses S. Grant proclaimed the Yellow Stone region a public park. It was the first national park in the world. After Yellow Stone became a public park, many other areas of great scenic importance were set aside. And in 1916 the national park service was established to manage these parks. As a park ranger, I am an employee of the national park service. In the national park, park rangers are on duty at all times to answer questions and help visitors in any difficulty. Nature walks, guided tours and campfires talks axe offered by specially trained staff members. The park service also protects the animals and plants within the park.
