Let's set off on an exciting journey to discover our country's four major plateaus(高原).
The Qinghai-Xizang Plateau in southwest China is the largest of the four plateaus. 1 With an average altitude(海拔) of over 4,000 meters，it is the highest plateau in the world and is known as the "roof of the world". This plateau is the birthplace of many Chinese rivers and has over 1,000 lakes，with Qinghai Lake being the largest saltwater lake.
In the north of China，we can find the Inner Mongolian Plateau. As the second largest plateau，it's about 700,000 square kilometers. It lies mostly between 1,000 and 1,200 meters above sea level. The plateau is mostly flat and has wide grassland. 2 The Loess Plateau is the third largest plateau in our country. It rises between 1,000 and 2,000 meters above sea level. The plateau was named after the yellowish soil(土壤) that covers the area. 3 Through many studies，some Chinese scientists hold that it was carried by the north wind from the Inner Mongolian Plateau and the Mongolian inland areas over thousands of years.
The Yunnan-Kweichow Plateau is the smallest among the four major plateaus. It mainly spreads over the provinces of Yunnan and Guizhou. The plateau has a great difference in altitude，from 400 to 3,500 meters above sea level，and it goes down from the northwest to the southeast. 4 It has many mountains and valleys.
5 Together，they make up the wonderful plateau sight of China.
A. The plateau is not flat.
B. Which of the four major plateaus is the largest?
C. These four plateaus each have their own beauty.
D. It covers nearly a quarter of the national land area.
E. You may wonder where the yellowish soil came from.
F. However，you'll also find some areas of the Gobi desert there.
G. The Loess Plateau soil loss is very serious because there are fewer and fewer plants.

答案
三、【语篇解读】本文是一篇说明文。文章主要介绍了中国的四大高原：青藏高原、内蒙古高原、黄土高原和云贵高原。
1. D 根据上文“The Qinghai-Xizang Plateau in southwest China is the largest of the four plateaus.”可知此处应介绍青藏高原的面积；D 项“它覆盖了全国近四分之一的土地面积。”符合语境。故选 D。
2. F 根据上文“The plateau is mostly flat and has wide grassland.”可知此处应进一步介绍内蒙古高原的其他特征；F 项“然而，你也会在那里发现一些戈壁沙漠地区。”符合语境。故选 F。
3. E 根据上文“The plateau was named after the yellowish soil that covers the area.”和下文“Through many studies... over thousands of years.”可知此处应引出黄土高原的黄土来源问题；E 项“你可能会好奇这些淡黄色的土壤从哪里来。”符合语境。故选 E。
4. A 根据下文“It has many mountains and valleys.”可知云贵高原的地貌有山和峡谷，并不平坦。故选 A。
5. C 根据上文对四大高原的介绍和下文“Together, they make up the wonderful plateau sight of China.”可知此处总结四大高原；C 项“这四大高原各有其美。”符合语境。故选 C。
