Chaka Salt Lake is a salt lake in Qinghai Province. It is about 3,100 meters high and covers about 105 square kilometers. It is rich in salt, with a thick salt bed close to the lake surface. That makes the lake a main source (来源) of salt in our country. On a clear day, the lake offers the beautiful reflection (映像) of the blue sky. That is why people call it “Sky Mirror.” Because of its wonderful views, people see the lake as one of the “must-go” places in China. The beautiful sunrise and sunset are the most beautiful. Every July, many visitors come to Chaka Salt Lake. They stay until the end of August, because they don’t want to miss the best time to visit. If you want to go on a trip to the lake, the following tips may be helpful. ◆ Do not eat the salt in the lake directly. ◆ Wear sunglasses and a hat because of the strong sunshine. ◆ Prepare some medicine for the weak and old people to deal with altitude sickness (高原病). When you travel to such a beautiful world of salt with snowy mountains and green grass around, you will feel like you are in a fairyland. 6．The writer introduces the topic by ________.

C．Travellers should wear a hat because of the strong sunshine B Nature is full of amazing things. 9 There are high mountains, long rivers, beautiful forests and deep oceans. Each part of nature has its own special beauty. Mountains are one of the most wonderful natural features. 10 Some mountains are covered with snow all year round, like the Himalayas. Climbing mountains can be a challenging but exciting experience. Rivers are also important parts of nature. 11 They provide water for people and animals. Many great civilizations grew up along big rivers, like the Yangtze River in China. 12 They are home to millions of different kinds of plants and animals. The Amazon Rainforest is the largest rainforest in the world. It is called the “lungs of the Earth” because it produces so much oxygen. 13 We should protect nature and enjoy its beauty.
