Mom, I think Im going to take a walk.Lara: All right.Narrator: Plants and animals are protected here; first, because the Tsingy is a nat
43、ional park, but more importantly because its almost impossible for people to go there. The name of the park means, “place where one cannot walk barefoot”, and in fact, you need more than a good pair of shoes to enter the Tsingy. The stone peaks at the top are almost as sharp as knives. Down below in
44、 the deep canyons, there are caves and water to deal with. This is no place for the casual tourist. On the other hand, this dramatic landscape is an advantage for the plants and animals that live in the Tsingy.

46、siting the Tsingy is a problem. Tourism was once a very important part of Madagascars economy, but political violence and other problems now keep many tourists away, and in the Tsingy, the rock formations are simply too difficult for most tourists to reach. Without tourists, there is a lack of money
47、 coming into the region. That means little money for research, so scientists arent sure how climate change, for example, is affecting the Tsingy .

128、as happy there. One day, there was a terrible earthquake.

129、rmed thousands of years ago. Thats when a princess had a dream about the most beautiful place she had ever seen. She described the dream to her father, who was king of all the land.

130、rincess was very happy.After Viewing To be continued V Viewing the Worldiewing the WorldExample Answer 3 According to our legend, the limestone peaks and caves in the Tsingy de Bemaraha used to be flat land. One day, the rocks started to grow like grass. They got taller and taller, and they were sha

132、 every year. Tourists come here to see the beautiful scenery, as well as one very interesting place near the sea. Its Northern Irelands first World Heritage site, and its called the Giants Causeway. Its an unusual formation of 40,000 pieces of basalt. The formation looks like stone columns and part
133、of walkway. But why do the stones look like this? Hill Dick used to be a tour guide here. He talks about the legend of Finn McCool.Hill Dick, Former Tour Guide: Finn was one of the great characters in Irish mythology or, if you like, Irish fact.Narrator: According to the legend, Finn was angry with
134、another giant who lived in Scotland25 miles across the sea. Finn decided to go to Scotland, but he wasnt a very good swimmer.To be continued V Viewing the Worldiewing the WorldNarrator: Therefore, in order to get across, he built a road using stones from a volcano, and he called it the Giants Causew
135、ay. People wonder if this story is true. And if you use your imagination, you might begin to believe it yourself. But scientists such as geologist Patrick McKeever have a different explanation for the unusual basalt formation. According to scientists, the Giants Causeway formed around 60 million yea
136、rs ago. That was long before human beings arrived. Dr. McKeever tells us how scientists think the causeway formed.Dr. Patrick McKeever, Geologist: The lava that was erupted was erupted very, very quickly and the flows were very, very thick.To be continued V Viewing the Worldiewing the WorldNarrator:
137、 To imagine what happened next, think about mud on a hot day. As the mud dries out, it shrinks, or becomes smaller, and cracks form on the surface. Dr. McKeever says something similar happened with the lava. The many-sided columns of basalt that make up the causeway are the result. People love to vi
138、sit this interesting place. Visitors have been coming here since the 1800s, and they dont need to believe either the legend or the scientific explanation in order to enjoy it.Hill Dick, Former Tour Guide: You can weave your own story around it. You can look at a rock and say, “That reminds me of som
139、ething or that looks like something ”Narrator: Many tourists and children visit the Giants Causeway each year and listen to the stories.

170、 and plants. Some of these are a threat to native species. For example, cats kill and eat native birds, and heather and pine species compete with native plants. Invasive foreign species are being killed to ensure the survival of native plants and animals. The most popular ski area on North Island is
171、 in the national park. The development of ski facilities would not be allowed today but people have been skiing there since 1913.

From the air, the parks white sand dunes do look like sheets drying in the wind, and its the wind that gives the dunes
184、their half-moon shapes. However, this park features a lot more than sand. Green and blue pools of water are left behind by the rain, fishermen go out to sea in their boats, and local people take care of herds of goats.So is the Lenis a desert, or a seascape? Is it a park, or a place where people liv

In fact, its not a true desert because it receives around 42 inches (120 centimeters) of rain each year.Listening 3To be continued F Further Listeningurther ListeningYet sand dunes as far as the eye can see, along with a lack of trees and other plants, suggest a desert.
