Some places are so beautiful or so important in the history of the United States that the na?tional government has set them aside to protect them. They are cared for so that everyone now and in the years to come can enjoy them.

 Ranking at the top of these places are the national parks. There are also historical parks and sites, national monuments, military parks, battlefield sites, national, cemeteries, memorials, parkways, and state parks. All together they make up the national park system of the United States. They are managed by the national park service.

 The oldest of the national parks is Yellowstone. It was made a park in 1872. Now the Unit?ed States has more than 30 national parks. But Yellowstone is still the largest with over two mil?lion acres.

 The government hires many workers to take care of the parks. There are scientists who know a great deal about wildlife. They see to it that the animals of the parks can roam around arid live as they naturally would. There are scientists who know a lot about insects and diseases that might harm the trees and wild flowers. There are scientists who know a great deal about the rocks of the region. There are rangers who see to it that the visitors follow the park rules.

 The national parks are wonderful playgrounds. There are places for campers. And there are cabins to rent and lodges with dining rooms where visitors may stay as they do in a hotel. In ad?dition,there are wonderful opportunities for hiking, taking boat trips, fishing, swimming, ex?ploring the wilderness, and even climbing mountains.

 The parks,however, are more than just interesting and beautiful. They have been called the biggest summer schools in the world. In each park there are scientist guides to explain to the visitors what they are seeing. There are museums, too,with exhibits to show visitors how the regions came to be as they are. Every year millions of visitors go to the national parks.

  Hawaii volcanoes are known as "shield" volcanoes, gently sloping mountains produced from a lot of very wet,fast-moving lava flows(溶岩流"Each Hawaiian island is made up of at least one primary volcano.

  When you move along the island chain from the south,where volcanoes are active,to the northwest part of the chain, the volcanoes become older―and less active. The active volcanoes erupt,then a type of rock known as basalt(玄武岩) was formed. When in a "molten" state, ba?salt produces the fluid lava that you see running down mountains and valleys.

  The Big island of Hawaii is home to five major volcanoes:Kilauca, Mauna Loa,Mauna Kea,Hualalai and Kohala. Mauna Loa is considered the largest active volcano on earth,even though it has not erupted since 1984. But Kilauea, home of the Hawaii Volcanoes National Park,is the most active volcano in terms of how much lava erupts each year,and the place most visitors come to see volcanic action.

  Ancient hawaiians believed that Kilauea was the physical manifestation(物理表现) of the fu?ry(猛 烈) of the mountain goddess, Pele. Kilauea has added 550 acres of coastal land since erup?tions began in 1983. Hot rivers of molten orange lava,flowing downhill, can be seen most any evening of the year.

  Hawaii Volcanoes National Park,two hours' drive from Kona and five hours' from Kohala on the Big Island, can be the highlight of any vacation. Open year-round, one can explore the many aspects of Kilauea volcano. Much of the best hiking on the Big Island is found within this park. And a visit to the park will give you an up-close view of a volcano.

  The Park,open 24 hours a day,is sometimes referred to as the "drive-in" volcano since it can be easily viewed by car. Even if you don't experience lava flows when you visit there is

much to see.

 You may know your mother, but how well do you really know Mother's Day? Cards,flowers,sales,TV specials,and a day off for someone who really deserves it―those are what probably come to mind for many people when they think of Mother's Day. But there's more to the story.

The earliest Mother's Day celebrations were held during spring in ancient Greece. The cele?brations honored Rhea,the Mother of the gods. During the 1600's,England celebrated a day called Mothering Sunday. On this day even servants(仆人) were given the day off to spend with their families. A mothering cake was even served with the family meal.

In the US,Mother's Day began in 1872 when Julia Ward Howe,who wrote the words to the famous song The Battle Hymn of the Republic, suggested it as a day devoted to peace. But it didn't really become popular until 1907 when Anna Jarvis started a campaign to honor mothers. She believed that mothers could help people get over the pain they experienced during the Civil War. The US isn't alone in devoting a day to mothers. Many other countries including Denmark,Finland, Italy,Turkey, Australia, Japan, and Belgium also honor their mothers in May. Other countries honor their mothers at different times of the year.

Learning more about Mother's Day and celebrating Mother's Day are important,but probably not as important as understanding what your own mother,or grandmother,or aunt has really done for you. And that will certainly be appreciated more than one day in a year.
