High mountains? White snow? Both answers are right, but in the mountains there is a place called the Valley of Flowers(花谷)and you can see a very different scene there. It is home to pretty flowers, wild plants and endangered animals. The Valley of Flowers is in Uttarakhand, one state in the north of India. It is more than 87.5 square kilometres. There are flowers everywhere. However, these flowers are not quite the same as what we often see. They grow in high places in the mountains. There are hundreds of different kinds of flowers in this valley. They bloom(开花)between June and September. When the flowers bloom, the valley looks like a magical world with different colours. There are also a lot of wild plants, such as trees and grass, in the Valley of Flowers. They are special. Some of them are hard to find anywhere else in the world! What's more, some endangered animals live in the valley, like snow leopards(雪豹). Now people have turned the Valley of Flowers into a national park. Visitors can't build anything or live there. They can't even stay there for too long at a time. They can only stay there for one day. It's probably not long enough for visitors to see all the real beauty there. 根据短文内容，选择正确答案。 (A)36.How does the writer start the text? A．By asking questions. B．By telling a story.
