1 . Yellowstone National Park became America's first national park in 1872. The National Park Service was formed 44 years later in 1916.Yellowstone, which is mostly in the state of Wyoming, is considered an example of the success of the National Park System.Humans have been present in Yellowstone for more than 11,000 years.

Yellowstone contains beautiful mountains, deep canyons(峡谷), lakes and rivers.The name Yellowstone comes from the river running through the area. At first known as Rock Yellow River, it became known as the Yellowstone River.

Yellowstone is host to many different species of plants. However, the park is most distinctive because of what lies underneath it. It sits on top of an ancient super volcano, known as The Yellowstone Caldera. The caldera is 48 by 72 kilometers. And it remains an active volcano.

It is believed that the last time the volcano erupted was one half million years ago. The area has had three major eruptions in the last three million years.Experts say it may erupt again in another 1,000 to 10,000 years. But each year, there are thousands of earthquakes at Yellowstone. Most are too small to be felt by people visiting the park.

Yellowstone is filled with the beauty of many hot water springs. hot water and gasses are trapped under the earth. they rush to the surface in the form of hot water and steam. Old Faithful is The most famous one . It erupts about every hour or hour and a half. The eruption can last from one and a half minutes up to 5 minutes. The amount of hot water it expels（排出） in that time can be as much as 31,000 liters or more.

In addition to its beauty and wonder, Yellowstone is an animal sanctuary（保护区）. It is home to the largest group of wild animals in the United States. As you travel through the park, you can sometimes see them in their natural habitat and hear their calls .

2 . The island of Port Cros is in the south of France. I first visited it about ten years ago with my wife. I had read that it was a magical place and it seemed fascinating (迷人的), but I couldn’t believe that it was true. In fact, it was much more magical than the tourist brochures (指南) had said.
The island is mountainous and covered in trees. The water around the island is transparent like glass. When I first visited it, there was mist rising from the trees. The little harbor looked mysterious and remote: tall palm trees, a few shops and restaurants, no cars, motorcycles or bikes.
It is not by chance that the island has kept its natural beauty. Once, it was privately owned and the owners always wanted to keep it in its natural state. In 1963, Port Cros became a national park. The park directors made some rules to protect the island. They didn’t allow any new building projects. There is only one hotel and no camping is allowed. Visitors can’t use mountain bikes or smoke on the island. Sailing boats that visit the island mustn’t damage the bottom of the sea or pollute the water around it.
When we arrived, we started walking to the beach of Port-Man, which was the furthest beach from the port. It took us two hours and when we arrived, the beach was deserted. It seemed that we were the only people on the island. Time seemed to stop. It was so beautiful that we stayed there all day. I visited there again last summer. Nothing had changed. The island still looked magical and mysterious, still with few tourists. It must be wonderful to stay the night on the island, I thought. After all the visitors have gone, the island must be so quiet—a real paradise (天堂)!
